Control Features

Engine Stop Switch

The stop

Throttle lever

switch is a red colored rocker switch located on the left-hand handle bar. To start and run the engine, this switch must be placed in the on, O, position. The vehicle is also equipped with a safety brake switch which will prevent the engine from starting until the parking brake is engaged. To stop your engine, place the switch to the stop, X, position. In the stop, X, position the ignition system is grounded preventing the spark plug from firing. This switch can also be used as a safety or emergency stop switch.
The throttle lever is located on the right-hand handle bar below the grip. To operate the throttle lever, place your right thumb on the lever and press forward to increase your speed. To decrease your speed, reduce your pressure on the lever and the spring tension will automatically reduce your speed.

Manual choke lever (9)

All Viper models are equipped with a manually operated carburetor choke system. This choke is operated by the lever at the bottom of the left hand control switch. When first starting the engine,(cold start), place the lever in the full left position, (Choke closed or on) As the engine warms return the lever to the full right position. (Choke open or off).

The travel of the throttle lever is controlled by the throttle stop bolt. As your operator gains more experience, you can increase the throttle travel to allow for additional speed to be obtained. To increase the throttles travel, thus increasing the maximum speed, turn the throttle stop bolt counter clockwise. To decrease the throttles travel, thus decreasing the maximum speed, turn the throttle stop bolt clockwise. The throttle cable should be adjusted so there is 2mm, (1/8) free travel at the lever before the throttle starts to open.

Front and Rear Brakes
This vehicle is equipped with dual front mechanical drum brakes and a rear hydraulic disc brake. (Viper 70 Viper 90 & Viper 90R) (Viper 50M is equipped with rear hydraulic disc brake only) The front brakes are controlled by the long brake lever on the right-handle bar. The rear brake is controlled by the long lever on the left-handle bar. The rear brake is the primary stopping brake on your vehicle. Using the rear brake to stop your vehicle will prevent steering control loss. Use your front and rear brakes in combination to control your speed while descending a grade. Use caution not to apply too much pressure to your front brakes so that the wheels lock up, stop turning, and causing a loss of steering control. If the front wheels lock up, and stop turning, lightly reduce the pressure on the front brake lever until they unlock and start to turn.
If your engine fails to start, ensure that the engine stop switch is in the on, O, position and that the parking brake is engaged.

Safety Tether Switch

The Viper 50M and Viper 70 models are equipped with a safety tether switch (optional on Viper 90R). The switch is located on the left hand side of the handlebars. The switch cap must be fully engaged for the vehicle to start and run. The cap is tied to a tether that should be worn around the rider wrist. In case of an emergency a simple pull on the tether will disengage the switch and stop the engine.

Parking Brake

The front brake lever has a button located at the pivot point to lock the brake in the, O, on position. This should be engaged as a parking brake whenever the vehicle is not in operation.

Remote Stop/Start Switch

This feature must be engaged in order to start the engine. The brake lever has a safety switch built in to prevent the engine from starting while the brake is disengaged.
The Viper 50M come equipped with a remote Stop/Start key ring switch. (This feature is an optional kit for the Viper 70 & Viper 90. A remote Stop Only kit is optional for the Viper 90R). The remote switch has two buttons, a Stop button which will stop the engine when pressed. The effective range of the switch is 30 feet unobstructed.

Page 9

Once the unit has been stopped with the remote switch you must press the run button in order for the unit to be restarted. This action resets the remote receiver on the unit. The unit may also be started remotely by pressing both the Stop & Run buttons together.
Replace the cap if damaged or if it will not seal to the tank. Tighten the cap snugly, being careful not to over tighten. Over tightening the cap can cause damage to the cap or seal. The fuel tank capacity is 4.5 liters, 1.2 gal, including a reserve of 0.8 liters, 0.2 gal. Use unleaded automobile gasoline with an octane level of 91 or higher.
Safety Note: Always test the remote
switch before beginning a riding session. The remote switch is operated by a battery which should be replace one a year. You can obtain a replacement battery at your local department store.
NEVER REFUEL YOUR ATV when the engine is HOT. Wait 30 minutes after turning
off the unit before refueling. Spilling fuel on a HOT engine could cause a fire. Wipe up any fuel spills before re-starting.

Fuel Tank

The fuel tank fill cap is located on top of the

Fuel Valve

The unit is equipped with a three way fuel valve located on the left side of the unit just below the
unit just ahead of the seat. The cap contains a vent to prevent a vacuum from forming in the tank as fuel is used. The vent tube must be attached to the cap and inserted in the vent tube holder hole while operating the unit. The fuel cap vent and vent tube must be clean and clear of obstructions for the unit to operate normally. You can check the vent and vent tube by blowing air through the tube. If you can not blow through the vent tube and cap you must clean the vent and tube or replace them. Every time you refuel your unit, check the rubber seal inside the cap for cuts, tears and dirt. Clean or replace the seal if it becomes worn or torn. The seal must be in good condition to insure a proper seal of the cap to the tank to prevent fuel spills. DO NOT allow dirt or other debris to enter the tank when refueling.

seat. The valve has three settings; OFF, ON and RES. With the valve in the OFF position fuel is held in the tank and is prevented from flowing to the carburetor. The valve should be placed in the OFF position whenever the unit is not being operated. Place the valve in the ON position for normal operation of the unit. This allows fuel to flow to the carburetor for normal operating. The RES position allows fuel to flow from the small reserve in the tank to allow the unit to be taken to a refueling location.

Page 10

When you have to switch to the RES position you must refuel the unit as soon as possible. ALWAYS CHECK YOUR Fuel level before you start riding your ATV. Remember: You can drive further in one hour on your ATV than you can walk in one day.
DO NOT start or operate the engine if the fuel filter or lines are leaking. Leaking fuel can cause a fire.

Engine Oil Tank

2 Cycle Engine

Inline Fuel Filter

Your ATV is equipped with an inline fuel filter to prevent dirt and debris from entering the carburetor and engine.
Your ATV uses 2 cycle oil to lubricate the engine. The oil tank is located under the seat at the front of the unit. Oil is drawn from this tank by an oil injector pump when the engine is operating. Check the filter for dirt or damage before each ride and at each refueling. Replace the filter if dirty or damaged. The filter should be replaced every 600 hours of operation and at the start of each season. To replace the filter, first turn the fuel valve to the OFF position. Then carefully compress the wire clamp rings until the clamp is free of the fuel line. Slide each clamp away from the filter about. Remove the filter from the fuel line by holding the line and pulling the filter. Install the new filter by inserting the filter into the fuel line and returning the clamps to the original position. Turn the fuel valve to the ON position and check for leaks. Inspect the fuel lines for cuts, abrasions and deterioration. Replace fuel lines as needed.

Oil Level Warning Light

The unit is also equipped with an oil level indicator lamp. The lamp will light when the oil level in the tank is low. When the lamp is lit you MUST refill the oil tank.

To bleed the air will require two people to perform the following procedure.
Caution: DO NOT allow dirt to fall into the reservoir.
Refold the cover gasket as shown in picture and replace cover and bolts
1. Place a drain pan under the brake caliper to catch the fluid. 2. Open the bleeder valve turn counter clockwise. 3. Squeeze the brake lever to expel air from the system. 4. While holding the brake lever, close the bleeder valve. 5. Repeat steps 2 through 4 until the brake fluid coming from the bleeder valve is a solid stream without any air, then close the valve and replace rubber protection cap. 6. Test the brake system by squeezing the lever, the lever should feel firm and stop without fading.

Purging Brake Lines

For the hydraulic brake system to operate safely, the brake system must be purged of air in the lines and reservoir.

Engine serial number is located on the left-hand side of the engine on the crankcase housing.

Fuel Tank

NEVER REFUEL YOUR ATV when the engine is HOT. Wait 30 minutes after turning
off the unit before refueling. Spilling fuel on a HOT engine could cause a fire. Wipe up any fuel spills before re-starting.

Fuel Valve

The fuel tank fill cap is located on top of the unit just ahead of the seat. The cap contains a vent to prevent a vacuum from forming in the tank as fuel is used. The vent tube must be attached to the cap and inserted in the vent tube holder hole while operating the unit. The fuel cap vent and vent tube must be clean and clear of obstructions for the unit to operate normally. You can check the vent and vent tube by blowing air through the tube. If you can not blow through the vent tube and cap you must clean the vent and tube or replace them. Every time you refuel your unit, check the rubber seal inside the cap for cuts, tears and dirt. Clean or replace the seal if it becomes worn or torn. The seal must be in good condition to insure a proper seal of the cap to
The unit is equipped with a three way fuel valve located on the left side of the unit just below the seat. The valve has three settings; OFF, ON and RES. With the valve in the OFF position fuel is held in the tank and is prevented from flowing to the carburetor. The valve should be placed in the OFF position whenever the unit is not being operated. Place the valve in the ON position for

Page 10

normal operation of the unit. This allows fuel to flow to the carburetor for normal operating. The RES position allows fuel to flow from the small reserve in the tank to allow the unit to be taken to a refueling location. When you have to switch to the RES position you must refuel the unit as soon as possible. ALWAYS CHECK YOUR Fuel level before you start riding your ATV. Remember: You can drive further in one hour on your ATV than you can walk in one day.
returning the clamps to the original position. Turn the fuel valve to the ON position and check for leaks. Inspect the fuel lines for cuts, abrasions and deterioration. Replace fuel lines as needed. DO NOT start or operate the engine if the fuel filter or lines are leaking. Leaking fuel can cause a fire.

Engine Oil

Your ATV uses an automotive type engine oil to lubricate and cool the engine. The engine oil dip stick is located on the right hand side of the engine just forward of the front chain guard.

Inline Fuel Filter

Your ATV is equipped with an inline fuel filter to prevent dirt and debris from entering the carburetor and engine. Check the filter for dirt or damage before each ride and at each refueling. Replace the filter if dirty or damaged. The filter should be replaced every 600 hours of operation and at the start of each season. To replace the filter, first turn the fuel valve to the OFF position. Then carefully compress the wire clamp rings until the clamp is free of the fuel line. Slide each clamp away from the filter about. Remove the filter from the fuel line by holding the line and pulling the filter. Install the new filter by inserting the filter into the fuel line and
DO NOT allow the engine to operate with a low oil level. Doing so will result in extensive damage to your engine. This damage is not covered under the warranty.
Checking the engine oil level
To check your engine oil level, park the unit on level area. Always check the oil level with the engine off and cold. Checking the oil level in a hot engine can give you a false reading. CAUTION: Removing the oil dipstick while the engine is running can cause hot oil to splash out of the crankcase and cause burns.

Page 11

Remove the dip stick by turning counter clockwise until the threads are fully disengaged. Pull the dip stick from the crankcase and check the oil level as indicated on the stick. The oil level should fall between the upper and lower limit line on the stick. If the engine oil is low add oil thought the dipstick hole until the dip stick read full or has reached the upper limit line. DO NOT over fill the crankcase as this can result in sever engine damage. Your E-TON engine requires SAE 20W-40 engine oil, and has a crankcase capacity of
70cc Engine = 100cc / 3.4oz 90cc Engine with Reverse = 300cc / 10.2oz
Always check the engine oil level before each riding session.

Changing the engine oil

The engine oil should be change at the beginning of each riding season and at every 100 hours of operation. When operating in dusty our humid conditions the oil should be change more frequently.
To change the engine oil in your E-TON engine follow these steps: 1. Place an oil catch pan directly below the engine crankcase. 2. Remove the crankcase drain plug located on the bottom of the crankcase on the underside of the unit. 3. Remove the engine oil dipstick located on the right hand side of the crankcase directly below the transmission shift lever. 4. Allow the oil to drain completely (1530min). 5.

Tires and Wheels
Tire & Wheel Inspection.
It is important to inspect your tires and wheels for damage and wear before each riding session. Inspect each tire for cuts, tears and punctures. Inspect the wheel rim for dents and separation of the wheel from the tire bead. Replace any tire or wheel found to be damaged. Operating your ATV with damaged tires or wheels is dangerous. Damaged tires or wheels can result in a sudden loss of tire pressure and control which could result in injuries. Check your tire pressure before each riding session and at each refueling operation. Always check the pressure when the tires are cool. Use the tire pressure gauge that came with your ATV to check the tire pressure.
2. Clean dirt from around spark plug base with brush or air. 3. Remove spark plug with spark plug wrench. 4. Set the spark plug gap on the new plug to 0.023 5. Install the new plug screwing it in finger tight and then use the plug wrench to screw the plug in another turn. 6. Inspect the spark plug wire for cuts, nicks or other damage. Replace as needed.

Required maintenance and cleaning:

Air Filtration System

Air Filter Maintenance
To maintain the highest performance from your engine and to reduce excessive wear that could cause engine failure, the engine requires a continuous flow of clean air. Air is taken into the engine through air filters to clean the air prior to mixing it with fuel in the carburetor.
1. After every 60 hours of operation the Spark Arrester has to be cleaned by loosening the retaining nut using a 10mm socket. Using pliers turn the sleeve of the Spark Arrester counterclockwise and pull out. Clean the screen with an exhaust cleaning solution and replace, securing it by tightening the retaining nut.

During normal operation the filters accumulate dirt from the air and will need to be cleaned to maintain the proper air flow. The filters should be cleaned every 30 days, more often if you ride in a dusty or dirty environment and the elements should be replaced every year.
2. After every 200 hours of operation the Spark Arrester has to be replaced by loosening the retaining nut using a 10mm socket or wrench. Using pliers turn the sleeve of the Spark Arrester counterclockwise and pull out. Replace a new Spark Arrester and secure it by tightening the retaining nut.
The air filter box is located on top of the engine below the seat. It is a black cylinder about 4 across and is attached to the crankcase with two bolts and the carburetor by a tube.

To clean the filter

1. Remove the air filter box covers, (LH and RH). 2. Remove the filter elements from the air box. 3. Wash the elements in a non-flammable solvent such as Air-Filter cleaner from your local auto parts dealer. 4. Dry the elements completely before continuing.

Page 16

5. Soak the elements in clean engine oil until completely saturated. 6. Squeeze out the excess oil until the element does not drip any oil. 7. Allow the elements to dry. 8. Clean the filter screens using a brush of vacuum 9. Reinstall the Screens, elements and cover.

Starting Procedure

The following procedure must be followed each time you start your unit. Park the unit on a level surface and lock the parking brake.

Page 21

Turning your ATV
Learning to turn your ATV requires you to learn to shift your weight and control the throttle to allow the rear wheels to turn properly. When making a turn, the wheels on the outside of the turn must travel a wider radius and thus a greater distance than the inside wheels of the turn. Since the rear axle does not permit a different rate of rotation, it is not enough to merely steer your ATV into the turn. To turn properly, steer in the direction of the turn and lean your body to the inside of the turn while supporting your weight on the outer footrest. Use the throttle to maintain power throughout the turn. If you do not use this turning technique the unit will have a tendency to continue in a straight line. If this occurs, release the throttle lever to allow the unit to stop. Avoid braking or accelerating until you have regained directional control.

Parking Your ATV

1. Always park your ATV on a level surface. 2. Turn the ignition key to the OFF position to stop the engine. 3. Set the engine stop switch to OFF position. 4. Engage the parking brake locking button. 5. Turn the fuel valve to the OFF position. 6. Remove the ignition key to prevent unauthorized use or theft of your ATV.
