grease replacement when any grease is leaking form
loosened screw.
Further use of the rotary hammer despite the grease
shortage causes damage to reduce the service life.
CAUTION:
A specific grease (FG-6A) is used with this machine,
therefore, the normal performance of the machine may
be badly affected by use of different grease. Please be
sure to let one of our service centers to undertake
replacement of the grease.
MAINTENANCE AND INSPECTION
1. Inspecting the tool
Since use of a dull tool will degrade efficiency and
cause possible motor malfunction, sharpen or
replace the tool 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. Cleaning on the outside
When the power tool is stained, wipe with a soft
dry cloth or a cloth moistened with soapy water.
Do not use chloric solvents, gasoline or paint thinner,
as they melt plastics.
5. Storage
Store the power tool in a place in which the
temperature is less than 40°C and out of reach of
children.
