FUNCTIONAL DESCRIPTION

CAUTION:
Always be sure that the tool is switched off and
•
unplugged before adjusting or checking function
on the tool.
Switch action
CAUTION:
Before plugging in the tool, always check to see
•
that the switch trigger actuates properly and
returns to the "OFF" position when released.
Switch can be locked in "ON" position for ease of
•
operator comfort during extended use. Apply
caution when locking tool in "ON" position and
maintain firm grasp on tool.
Fig.1
To start the tool, simply pull 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 side grip (auxiliary handle)
Fig.2
The side grip swings around to either side, allowing
easy handling of the tool in any position. Loosen the
side grip by turning it counterclockwise, swing it to the
desired position and then tighten it by turning clockwise.
Bit grease (optional accessory)
Fig.3
Coat the bit shank head beforehand with a small
amount of bit grease (about 0.5 - 1 g; 0.02 - 0.04 oz.).
This chuck lubrication assures smooth action and longer
service life.
Installing or removing the bit
Fig.4
Fig.5
Pull the change ring down all the way and insert the bit
into the tool holder as far as it will go. Release the
change ring and it will return automatically to its original
position to secure the bit. 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 change ring down all
the way and pull the bit out.

OPERATION

CAUTION:
Make sure the work material is secured and not
•
unstable. Flown object may cause personal injury.
Do not pull the tool out forcibly even the bit gets
•
stuck. Loss of control may cause injury.
Always use the side grip (auxiliary handle) and
•
firmly hold the tool by both side grip and switch
handle during operations.
Fig.6
Chipping/Scaling/Demolition
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.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.
Fig.8
Use a screwdriver to remove the rear cover.
Fig.9
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.
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be
performed by Makita Authorized Service Centers,
always using Makita replacement parts.
