1Warning
Caution:
• Pb free solder has a higher melting point that standard solder; Typically the melting point is 50 - 70°F (30 - 40°C) higher. Please
use a soldering iron with temperature control and adjust it to 750 ± 20°F (400 ± 10°C). In case of using high temperature solder-
ing iron, please be careful not to heat too long.
• Pb free solder will tend to splash when heated too high (about 1100°F / 600°C).

3.2. Trial Operation (After Checking Troubleshooting Guide)
3.2.1. Assembly
• Confirm if there is no gap between housing A and B by pinching lead wires.
• There is no dust or deformation on battery terminals.
• Confirm if there is no dirt when repairing.
3.2.2. Operation
• Check whether the tool operates properly in both the forward and reveres directions.
• Check whether the LED light illuminates when the trigger depressed and turns off when the trigger is released.
• Check whether the tool speed increases continuously as the trigger is gradually engaged.
• Check whether the tool speed is normal after repair and reassembly.
1 (Low mode) 110 to 400 rpm
2 (High mode) 320 to 1300 rpm
• Check whether the tool becomes hot in a short period of time under conditions of no load.
• Set the gradation on the clutch handle to “Off,” operate the tool under conditions of no load, and check whether the clutch oper-
ates with the chuck in the locked state.
• Rotate the keyless chuck and check whether the chuck’s three clips move.
• Rotate the clutch handle and check whether the clutch switches properly.
• Check whether the battery level indicator illuminates when the trigger depressed and turns off when the trigger is released.
3.2.3. Integrity
• Confirm if the chuck is assembled firmly and chuck jaws operate normally.
• With the switch activated, shake the tool back and forth and up and down and verify that its sound does not change excessively.

4 Disassembly and Assembly Instructions
* To assemble the tool, start with 4-8 and proceed to 4-1.
4.1. Removing the keyless chuck
4.2. Removing the handle hoop
4.3. Removing the housing

7
4.4. Removing the Motor and switch block
4.5. Removing the driving block and motor

8
4.6. Attaching the driving block
*Because the motor mount is attached to the gear case block (WEY7530L4058) in order to keep internal parts from
falling off, attach it to the motor after removing it from the block. (If there is no motor mount attached to the motor, use
the motor mount on the driving block.)
4.7. Attaching the LED PCB
4.8. Attaching the driving block and motor
