*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.
GREASE REPLACEMENT
This Rotary Hammer is of full air-tight construction to protect
against dust and to prevent lubricant leakage.
Therefore, this Rotary Hammer can be used without
lubrication for long periods. Replace the grease as described
below.
Grease Replacement Period
After purchase, replace grease after every 6 months of
usage. Ask for grease replacement at the nearest authorized
Service Center.
MAINTENANCE AND INSPECTION
1. Inspecting the tool bits
Since use of a dull tool will cause motor malfunctioning
and degraded effi ciency, replace the tool bit with new
ones or resharpen them without delay when abrasion is
noted.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that
they are properly tightened. Should any of the screws be
loose, retighten them immediately. Failure to do so could
result in serious hazard.
