(gained from repeated use) replace strict adherence
to safety rules for the subject product.
MISUSE or failure to follow the safety rules stated in
this instruction manual may cause serious personal
injury.
FUNCTIONAL DESCRIPTION
CAUTION:
• Always be sure that the tool is switched off and
unplugged before adjusting or checking function on
the tool.
Switch action (Fig. 1)
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.
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
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. 7)
Use a screwdriver to remove the rear cover.
(Fig. 8)
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.
(Fig. 9)
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.
