HOW TO USE

CAUTION:
To prevent accidents, make sure to turn the
switch off and disconnect the plug from the
receptacle when the drill pits and other
various parts are installed or removed. The
power switch should also be turned off during
a work break and after work.
1. Switch operation
The rotation speed of the drill bit can be
controlled steplessly by varying the amount
that the trigger switch is pulled. Speed is low
when the trigger switch is pulled slightly and
increases as the switch is pulled more.
2. Rotation + Striking
This rotary hammer can be set to rotation and
striking mode by turning the change lever fully
counterclockwise to
(1) Mount the drill bit.
(2) Pull the trigger switch after applying the drill
bit tip to the drilling position (Fig. 6)
(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. 6.
3. Rotation only
This rotary hammer can be set to rotation only
mode by turning the change lever fully
clockwise to mark. (Fig. 7)
To drill a wood or metal material using the
separately sold drill chuck and chuck adaptor,
proceed as follows. Installing drill chuck and
chuck adaptor (Fig. 8):
(1) Mount the drill chuck to the chuck
adaptor.
(2) The part of the SDS-plus shank is the same as
the drill bit. Therefore, refer to the item of
"Mounting the drill bit" for attaching it.
