6. HAMMER to ROTATION changeover
(Fig. 9)
The Hammer Drill can be switched from
HAMMER (hammer plus rotation) to ROTA-
TION (rotation only) by turning the change
lever. When boring concrete, stone, tile or
similar hard materials, turning the change
lever to HAMMER side. The drill head ham-
mers against the material while continuing
to rotate.
When boring metal, wood or plastic, turning
the change lever to ROTATION side. The
hammer drill can be used as an ordinary
electric drill.
CAUTION:
Do not use the Hammer Drill in the HAMMER function if the material can be bored by
rotation only. Such action will not only reduce drill efficiency, but may also damage the
drill tip.
NOTE
The change lever may not turn smoothly when changing from hammer drill mode to drill
mode. (Fig. 9)
In this case, operate the machine for few seconds.
The spindle shaft will then be pushed forward, and the change lever can be moved
smoothly.
7. High-speed/Low-speed changeover (Fig.
10)
Prior to changing speed, ensure that the
hammer drill has come to a complete stop.
To change speed, depress the shift lock and
slide in to the appropriate direction, as indi-
cated by the arrow in Fig. 10. The numeral "1"
engraved in the hammer drill body denotes
low speed, the numeral "2" denotes high
speed.
CAUTION:
When changing the rotational speed with the shift lock, confirm that the switch is off.
Changing the speed while the motor is rotating will damage the gears.
