[2] Performance Comparison
Note: 1. With 2.6Ah Ni-MH battery, Makita models were tested. 2. The test results depend to a great extent on the hardness of materials, etc. 3. The numbers in the bar graphs are relative values when the capacity of the predecessor model (6317D/6337D/6347D) is indexed at 100. 4. The 3rd speed of the new models is designed for faster drilling/fastening with rotational speed higher than that of the predecessor models. Therefore, in some applications, the energy consumption may get higher, resulting in work volume smaller than the predecessor models.

Repair
[1] DISASSEMBLY/ ASSEMBLY [1] -1. Drill Chuck

REMOVAL

When replacing Gear assembly, remove Drill chuck first as described below. (When replacing only Housing, you need not remove Drill chuck.) 1) After opening the chuck jaws to the full, remove the chuck screw (M6x22 (-) Flat head screw) by turning it clockwise. Use impact driver drill if it is difficult to remove the screw. 2) Slide Speed change lever to the position of "1" (1st speed), and slide Action mode change lever to the drill mode as illustrated in Fig. 1. Secure the short arm of a hex wrench with the chuck jaws. Hold the machine firmly, and then remove Drill chuck by hitting the long arm of the hex wrench using plastic hammer to turn Drill chuck counterclockwise. (Fig. 2) Fig. 1 Fig. 2

Note: Fig. 3 This product has "Spindle Lock system". [WRONG] After hex wrench is secured in Drill chuck, it is impossible to turn the wrench in order to adjust the position of its long arm. (Fig. 3) Therefore, make sure that the hex wrench is positioned as illustrated in Fig. 2 before securing it in drill chuck.

Caution: Place the tool on a work table so that Drill chuck touches the surface of the work table as illustrated to left in Fig. 4. Failure to follow this instruction can result in deformation of Spindle. Fig. 4 [CORRECT] Drill chuck [WRONG] Spindle can be deformed by the shock to hex wrench.

INSTALLATION

1) Make sure that Flat washer 13 is mounted to Spindle before installing Drill chuck. (Fig. 5) 2) Slide Speed change lever to the position of "1" (1st speed), and slide Action mode change lever to the drill mode as illustrated in Fig. 1. Push in F/R change lever for the forward rotation mode. (Fig. 6) Secure the short arm of a hex wrench in the chuck jaws, and the long arm in vise. Hold the grip of the machine firmly so that your hand cannot be pulled away by reaction torque. And then tighten Spindle into Drill chuck by pulling the trigger of Switch until Spindle is locked. (Fig. 6) Note: Release the trigger of Switch just after Spindle is locked. Do not keep on pulling the trigger for longer than one second. 3) Fasten Drill chuck to Spindle with the chuck screw (M6x22 (-) Flat head screw) by turning it counterclockwise. If you reuse a screw removed from Drill chuck, apply an appropriate amount of adhesive (ThreeBond 1321B/ 1342 or Loctite 242) to the screw for secure fastening. Fig. 5 Fig. 6 Hex wrench

1) Before installing Speed change lever on Gear assembly, make sure that; a. Two Leaf springs are installed to Speed change lever as illustrated to left in Fig. 7. b. Two compression springs are installed to speed change lever as illustrated to right in Fig. 7. 2) Assemble Speed change lever to the projection on Gear assembly. (Fig. 8)
