How to use the demolition hammer*
Replacing carbon brushes
Selecting accessories
* Operate this Demolition Hammer by utilizing its empty
weight. The performance will not be better even if it is
pressed or thrust forcibly against the work surface.
Hold this Demolition Hammer with a force just suffi cient
to counteract the reaction.
Warming up (Fig. 9)
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.
GREASE REPLACEMENT
This Demolition Hammer is of full air-tight construction to
protect against dust and to prevent lubricant leakage.
Therefore, this Demolition 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
CAUTION
Be sure to switch OFF and disconnect the attachment
plug from the receptacle to avoid a serious accident.
1. Inspecting accessories
Since use of a dull accessory, such as a bull point, a
cutter, etc. will degrade effi ciency and cause possible
motor malfunction, sharpen or replace with a new one as
soon as 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.
3. Maintenance of the motor
The motor unit winding is the very "heart" of the power
tool. Exercise due care to ensure the winding does not
become damaged and/or wet with oil or water.
4. Inspecting the carbon brushes (Fig. 10)
The Motor employs carbon brushes which are
consumable parts. When they become worn to or near
the "wear limit" ⓐ, it results in motor trouble.
When an auto-stop carbon brush is equipped, the motor
will stop automatically. At that time, replace both carbon
brushes with new ones which have the same carbon
brush Numbers ⓑ shown in the Fig. 10. In addition,
always keep carbon brushes clean and ensure that they

slide freely within the brush holders.
