Bit angle (Fig. 10 & Fig. 11)
The bit can be secured at 12 different angles. To change
the bit angle, slide the change ring forward, then turn the
change ring to change the bit angle. At the desired angle,
slide the change ring back to the original position. The bit
will be secured in place.
NOTE:
• The change ring cannot turn when the bit is not
installed on the tool.

OPERATION

Chipping/Scaling/Demolition (Fig. 12 &
Fig. 13)
Always use the side grip (auxiliary handle) and firmly hold
the tool by both side grip and switch handle during
operations. Turn the tool on and apply slight pressure on
the tool so that the tool will not bounce around,
uncontrolled. Pressing very hard on the tool will not
increase the efficiency.

MAINTENANCE

CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.
Lubrication
CAUTION:
• This servicing should be performed by Makita
Authorized Service Centers only.
This tool requires no hourly or daily lubrication because it
has a grease-packed lubrication system. It should be
lubricated every time the carbon brushes are replaced.
Send the complete tool to Makita Authorized Service
Center for this lubrication service.
Run the tool for several minutes to warm it up. Switch off
and unplug the tool.
Loosen the four screws and remove the handle. Note that
the top screws are different from other screws. (Fig. 14)
Disconnect the connector by pulling them. (Fig. 15)
Loosen the four screws on crank cap and remove the
crank cap cover. (Fig. 16)
Wipe out the old grease inside and replace with a fresh
grease (30 g). Use only Makita genuine hammer grease
(optional accessory). Filling with more than the specified
amount of grease (approx. 30 g) can cause faulty
hammering action or tool failure. Fill only with the
specified amount of grease. (Fig. 17)
CAUTION:
• Be careful not to damage the connector or lead wires
especially when wiping out the old grease.
To reassemble the tool, follow the disassembling
procedure in reverse.
CAUTION:
• Do not tighten the crank cap excessively. It is made of
resin and is subject to breakage.
