ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Side handle (auxiliary handle) (Fig. 2)
The side handle can be either freely swiveled or secured
at one position for use during tool operation. Just loosen
the nut to swivel the handle freely.
To secure the handle at a fixed position, first loosen the
nut and swing the handle to the desired position for use.
Then tighten the nut firmly. If the set bolt turns together
with the nut when you secure the nut, see that the pro-
jecting portion of the side handle fits into the notch on the
head of the set bolt.
Installing or removing the bit (Fig. 3)
With the notched portion on the shank of the bit facing
toward the tool retainer, insert the bit into the tool holder
as far as it will go. Then pull out and turn the tool retainer
180° to secure the bit. After installing, always make sure
that the bit is securely held in place by trying to pull it out.
OPERATION
Chipping/Scaling/Demolition (Fig. 4)
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 attempting to perform inspection or
maintenance.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.
Replacing carbon brushes (Fig. 5, 6 & 7)
When the resin insulating tip inside the carbon brush is
exposed to contact the commutator, it will automatically
shut off the motor. When this occurs, both carbon
brushes should be replaced. Keep the carbon brushes
clean and free to slip in the holders. Both carbon brushes
should be replaced at the same time. Use only identical
carbon brushes.
Use a screwdriver to remove the holder cap plates.
Use a screwdriver to remove the brush holder caps. Take
out the worn carbon brushes, insert the new ones and
secure the brush holder caps.
Reinstall the holder cap plates firmly.
Lubrication (Fig. 8 & 9)
This tool requires no hourly or daily lubrication because it
has a grease-packed lubrication system. It should be
relubricated after every 6 months of operation. Send the
complete tool to Makita Authorized or Factory Service
Center for this lubrication service. However, if circum-
stances require that you should lubricate it by yourself,
proceed as follows.
Run the tool for several minutes to warm it up. Switch off
and unplug the tool.
Remove the crank cap using a hex wrench, then replen-
ish with fresh grease (60 g). Use only Makita genuine
hammer grease (optional accessory). Filling with more
than the specified amount of grease (approx. 60 g) can
cause faulty hammering action or tool failure. Fill only
with the specified amount of grease.
Reinstall the crank cap securely with the hex wrench.
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be per-
formed by Makita Authorized Service Centers, always
using Makita replacement parts.

Noise
The typical A-weighted noise level determined according
to EN60745:
Sound pressure level (L
Uncertainty (K): 3.13 dB (A)
The noise level under working may exceed 80 dB (A).
Wear ear protection
Vibration
The vibration total value (tri-axial vector sum) determined
according to EN60745:
Work mode: chiseling
Vibration emission (a
Uncertainty (K): 1.3 m/s
• The declared vibration emission value has been mea-
sured in accordance with the standard test method and
may be used for comparing one tool with another.
• The declared vibration emission value may also be
used in a preliminary assessment of exposure.
WARNING:
• The vibration emission during actual use of the power
tool can differ from the declared emission value
depending on the ways in which the tool is used.
• Be sure to identify safety measures to protect the oper-
ator that are based on an estimation of exposure in the
actual conditions of use (taking account of all parts of
the operating cycle such as the times when the tool is
switched off and when it is running idle in addition to
the trigger time).
