BENCH DRILL PTBM 350-13 For drilling in wood, plastic and metal
Please read carefully through the following information concerning safety and proper use. Before reading, fold out the page with the illustrations and make yourself familiar with all the functions of the equipment. Please read the operating instructions below and the accompanying safety advice carefully. Use the equipment only as described and for the indicated purposes. By doing this you will be able to work in complete safety and produce better results. Be careful to keep these advice notes and if necessary pass them on to a third party.

PROPER USE

The bench drill is intended for drilling in wood, plastic and metal using normal drill bits up to a maximum diameter () of 13 mm. Any other use of or modification to the machine shall be considered as improper use and could give rise to serious danger.

SPECIFIC SAFETY ADVICE

In addition, you must also read the advice in the accompanying booklet called "Safety advice" before using the equipment for the first time. When you are using the bench drill always wear ear protectors and protective glasses. We recommend that you wear robust antislip footwear, a working apron or close-fitting clothing, If you have long hair you should wear some sort of hair protection (such as a hair net, cap or headscarf) to ensure that your hair does not become trapped in moving machine parts or twisted about the drill bit or chuck. Do not wear gloves when drilling. Do not remove any mechanical or electrical safety devices. Always check that all safety devices are attached and properly fixed in place. Always check that the workpiece is firmly and securely clamped in place. Never drill a workpiece whilst holding it in your hands. Check that the chuck is properly attached. Never clean or lubricate the bench drill when it is in motion. Before adjusting, maintaining or repairing the drill, always remove the plug from the mains socket. Use a hand brush to remove drilling swarf. Ensure that you work safely by firmly fixing down the machine on to a working surface. Always keep the drive/ belt cover closed to keep hands and fingers out. Always use the key to open or close the drill chuck.

ASSEMBLY

The bench drill is supplied ready to assemble. Remove the parts carefully from the packaging and assemble the bench drill in the following manner: 1. 2. 3. 4. Insert the column into the base plate and tighten the screws (3 column/base fixing screws ). Place the drilling table on to the column and fix it in position using the table clamp screw. Fix the drill vice (4 drill vice screws ) on to the drilling table. Place the pre-assembled motor unit on to the column. The motor unit is attached by two hexagonal socket screws on the right hand side. 5. Attach the three armed handle/spindle control in the rise and fall shaft. 6. Attach the chuck firmly to the drill spindle cone. Attention: Clean the drill spindle cone thoroughly to remove all traces of grease.

SETTING UP THE MACHINE

Set the bench drill down on a firm surface and level it using a spirit level. We recommend that the machine is bolted down on to the supporting surface. Please ensure that the base plate is not subject to any additional forces as a result of being bolted down.

INSTALLATION AND FIRST USE
Check that the supply type, voltage and fuses comply with those specified for the machine. First clean any anti-rust coating carefully from the parts. Then oil the column.
SWITCHING THE MACHINE ON AND OFF
Insert the plug into the mains socket and switch on the machine using the "I button at the on/off switch. To switch off use the 0 button.
CHECKING AND TENSIONING THE V-BELT
Open the drive/belt cover and check the V-belt tension. If it is correctly adjusted the V-belt should be able to be moved approximately 1 cm in the middle between the two drive wheels. Loosen the adjustment screw and press the motor unit backwards before retightening the adjustment screw.

SETTING THE SPEED

The bench drill has 5 different speeds. The speed is set by simply repositioning the V-belt. To do this open the drive/belt cover , loosen the adjustment screw and place the V-belt on the relevant pair of drive wheels. Note: The top pair give the highest speed; the bottom pair the lowest ( =2600, = 1750, = 1250, = 900, = 600, see figure on page 3). Then tension the V-belt as described in the section on Tensioning the V-belt. Note: Inside the drive/belt cover there is a contact which must come together with an opposing contact (see ) on the drive/belt casing base when the drive cover is closed. The motor can only be restarted if the drive/belt cover is properly closed.
SETTING THE DRILLING TABLE
The drilling table can be adjusted by loosening the table clamp screw. Set the table so that there is an adequate distance between the workpiece top surface and the drill bit point. The table can be swung to the side, e.g. when you wish to work on a tall workpiece that can be attached directly to the base plate.
DEPTH STOP / DRILLING TO AN EXACT DEPTH
The depth stop with its scale allows you to drill to an exact depth. First of all press lightly down on to the top of the workpiece surface using the handle and set the drilling depth using the adjustment nut on the scale. Note: Make sure that you take into account the length of the drill bit point (normally approx. 5 mm) when determining the appropriate setting for the cylindrical part of a drilled hole.

INCLINED DRILLING

The drilling table can be rotated to drill angle holes or to accommodate workpieces with inclined ends. Release the hexagonal socket screws on the drilling table swivel joint. Place the table at the required slope and retighten the hexagonal socket screws.
ADVICE ON DRILLING WORKPIECES
The following points should be observed at all times:
always use sharp tools cool the drill bit with a suitable liquid use a special drill bit for drilling into stainless steel for very hard materials use a higher pressure at lower speed setting for soft materials apply light pressure at a higher speed Attention: too high a pressure overloads the motor and reduces the drilling speed small drills require a high drill speed larger drills require a lower drill speed The following table gives further helpful advice:
the correct speed is different for each material the cutting speed is dependent on the diameter of the drill and the rotation speed the table gives the approximate rotation speed please note that an average speed has been calculated for the listed materials and the rotation speeds have been rounded in some cases the calculated cutting speeds (CS) cannot be selected in practice - use the nearest available value
