*1 When drilling fragile materials, or when conducting
chipping operations or alignment operations, change
the tool's rotation speed in accordance with the task by
using the rotation speed selector switch.
NOTE
While the tool's motor is operating, rotation speed
cannot be adjusted by pressing the rotation speed
selector switch.
To adjust rotation speed, switch off the tool. Once the
motor has stopped, press the rotation speed selector
switch to adjust the speed.
*2 For detailed information regarding each tool, contact a
HiKOKI authorized service center.
Operate this Rotary Hammer by utilizing its own weight. The
performance will not be better even if it is pressed or thrust
forcibly against the work surface.
Hold this Rotary Hammer with a force just suffi cient to
counteract the reaction.
Warming up (Fig. 14)
The grease lubrication system in this unit may require
warming up in cold regions.
Position the end of the bit so makes contact with the
concrete, turn on the switch and perform the warming
up operation. Make sure that a hitting sound is produced
and then use the unit.
CAUTION
When the warming up operation is performed, hold the
side handle and the main body securely with both hands
to maintain a secure grip and be careful not to twist your
body by the jammed drill bit.
