(c) Does not rotate
HOW TO USE
1. Switch operation
When the switch trigger is depressed, the tool
rotates. When the switch trigger is released, the
tool stops.
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.
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.
