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 & 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 & 8)
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 rear cover.
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.
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: chiselling function with side grip
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).
