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).

• 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.
