CAUTION:
• Before plugging in the tool, always check to see that
the switch trigger actuates properly and returns to the
"OFF" position when released.
To start the tool, simply pull the switch trigger. Tool speed
is increased by increasing pressure on the switch trigger.
Release the switch trigger to stop.
For continuous operation, pull the switch trigger and then
push in the lock button.
To stop the tool from the locked position, pull the switch
trigger fully, then release it.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Installing casters (Fig. 2)
Install the casters securely with the bolts using the hex
wrench.
Installing or removing the bit (Fig. 3)
Clean the bit shank before installing the bit.
Insert the bit into the tool. Turn the bit and push it in until
it engages. (Fig. 4)
If the bit cannot be pushed in, remove the bit. Pull the
chuck cover down a couple of times. Then insert the bit
again. Turn the bit and push it in until it engages.
After installing, always make sure that the bit is securely
held in place by trying to pull it out.
To remove the bit, pull the chuck cover down all the way
and pull the bit out. (Fig. 5)
Bit angle (Fig. 6 & 7)
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.
OPERATION
CAUTION:
• Always use the grip and firmly hold the tool by both grip
and switch handle during operations. (Fig. 8)
Position the bit at the location to be chipped, then pull the
switch trigger. 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. (Fig. 9)
NOTE:
• When removing tiles with a scaling chisel, apply the
chisel to the bottom of tiles as shown in the figure. If
you operate the tool with the chisel applied to the top
surface of tiles, the service life of the chisel will be
shortened.
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.
To maintain product SAFETY and RELIABILITY, repairs,
carbon brush inspection and replacement, any other
maintenance or adjustment should be performed 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
Sound power level (L
Uncertainty (K): 3 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): 1.5 m/s
• The declared vibration emission value has been
measured 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
operator 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).
