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).

3.2.1. 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 turns on and off each time the LED light on/off button is depressed.
• Check whether the tool speed increases continuously as the trigger is gradually engaged.
• Check whether the tool speed is normal after repair and reassembly.
High mode: 0 to 2,500 rpm
Medium mode: 0 to 1,400 rpm
Low mode: 0 to 1,000 rpm
• Check whether the bit holder slides properly. Insert a bit and verify that it cannot be removed by lightly pulling on it.
• Check whether impact operation functions properly.
For an easy test of impact operation, check whether you can drill a universal screw (φ4.5X75mm) into a substrate Douglas fir
within about 5 seconds.
3.2.3. Integrity
• With the switch activated, shake the tool back and forth and up and down and verify that its sound does not change excessively.
