Oil feeding
Caution.
Prior to oil feeding, always
disconnect the plug from the power supply
receptacle. Since an oil chamber is built in
this Demolition hammer, it can be used for
approximately 20 days without supplying
lubrication oil, assuming that the chisel is
used continuously 3
–4 hours daily.
Feed oil into the oil tank as described below
before using the tool. (See Fig 6 - 7)
(1) When the tool is held upright look through
the oil gauge window to see if oil is visible, if
no oil shows oil must be installed before
operating.
If chisel is used without oil this could
seriously damaged the tool and forfeit any
warranty given.
(2) Before feeding oil, use the provided
wrench to remove the oil gauge (4). Be
careful not to lose the rubber packing
attached below the oil gauge.
(3) Check the oil level once daily, confirming
that oil is filled.
(4) After feeding oil, securely clamp the oil
gauge.
Note : Oil for the Demolition hammer is sold
separately, use Shell oil ROTELLA 40
(engine oil) or equivalent, this is sold at most
shops or filling stations anywhere.

Maintenance and inspection
1.
Inspecting the tool
When using dull tool bits this can cause
motor malfunction and degraded efficiency.
Always replace dull bits with new ones
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 injury.
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.
The motor employs carbon brushes that are
consumable parts; since an excessively worn
carbon brush could result in motor trouble,
replace the carbon brush. Wear limiter (6)
No of carbon brush (7). (See Fig 8)
