and 2,650 BPM just by turning the adjusting dial. This
can be done even while the tool is running. The dial is
marked 1 (lowest speed) to 5 (full speed). Refer to the
table below for the relationship between the number set-

Chipping / Scaling / Demolition (Fig. 7)
Hold the tool firmly with both hands. 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 carrying out any work on the tool.
Replacement of carbon brushes
(Fig. 8 & 9)
Whenever carbon brushes must be replaced, they cut out
the tool automatically. When this occurs, loosen the
screws which secure the rear cover. Pry up the rear
cover with a screwdriver and remove it. Then replace
both carbon brushes at the same time. Use only identical
carbon brushes.
Lubrication (Fig. 10 & 11)
This tool requires no hourly or daily lubrication because it
has a grease-packed lubrication system. Lubricate the
tool every time the carbon brushes are replaced.
Run the tool for several minutes to warm it up. Switch off
and unplug the tool. Remove the crank cap using a
socket wrench. Rest the tool on the table with the bit end
pointing upwards. This will allow the old grease to collect
inside the crank housing. Wipe out the old grease inside
and replace with a fresh grease (30 g). Use only Makita
genuine 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. Reinstall the crank
cap and tighten with the socket wrench. Do not tighten
the crank cap excessively. It is made of resin and is sub-
ject to breakage.
To maintain product safety and reliability, repairs, mainte-
nance or adjustment should be carried out by a Makita
Authorized Service Center.
