(a) Forward rotation

HOW TO USE

1. Switch operation

⅜ When the switch trigger is depressed, the tool

rotates. When the switch trigger is released, the
tool stops.

⅜ The rotational speed of the rotary hammer can be

controlled by varying the amount that the switch
trigger is pulled. Speed is low when the switch
trigger is pulled slightly and increases as the
switch trigger is pulled more.

⅜ When releasing the switch trigger, the brake will

be applied for immediate stopping.

2. Rotation + Striking

Align the “ ” mark with the “ ” mark by rotating
the change lever to set the “Rotation + Striking”
mode. (Fig. 12)

(1) Mount the drill bit.
(2) Pull the trigger switch after applying the drill bit

tip to the drilling position. (Fig. 13)

(3) Pushing the rotary hammer forcibly is not

necessary at all. Pushing slightly so that drill dust
comes out gradually is just sufficient.

CAUTION:

● When the drill bit touches an iron reinforcing rod,

the bit will stop immediately and the rotary
hammer will react to revolve. Therefore please
grip the side handle and handle tightly as shown
in Fig. 13.
