Operation; Maintenance - Makita DCE090 Instruction Manual

NOTE: The fitting depends on the shape of the faucet
to which you connect. Prepare a suitable commercial-
ly-bought fitting.
NOTE: If you use a water tap joint, prepare another
coupling sleeve and attach it to the other end of the
hose.
NOTE: When using a water pump, follow the instruc-
tions of your water pump to connect the water hose.
4. Push the coupling sleeve into the water inlet until it
locks with a click.

NOTICE:
Keep the cock closed until you start the
cutting operation with water feeding. For how to
feed water, refer to the section for the operation.

OPERATION

CAUTION:
Be sure to lock the cover for bat-
tery compartment before operating.
CAUTION:
Be sure to hold the workpiece
firmly down on a stable bench or table during
operation.
CAUTION:
Do not twist or force the tool in the
cut, or the motor may be overloaded or the work-
piece may break.
Cutting
CAUTION:
During operation, do not bring the
tool higher than your shoulder height.
► Fig.15
Hold the tool firmly. Grasp the handle with your right
hand and the grip with your left hand. To prevent electric
shock by accidental cutting of an electric cable, always
hold the grip by the designated portion as shown in the
figure.
► Fig.16: 1. Part to hold
Move the tool over the workpiece surface, keeping it
flat and advancing smoothly until the cutting is com-
pleted. Keep your cutting line straight and your speed of
advance uniform.
NOTE: When the battery cartridge temperature is
low, the tool may not work to its full capacity. At this
time, for example, use the tool for a light-duty cut for
a while until the battery cartridge warms up as high
as room temperature. Then, the tool can work to its
full capacity.
NOTE: If the cutting action of the diamond wheel
begins to diminish, dress the cutting edge of the
wheel using an old discarded coarse grit bench
grinder wheel or concrete block. Dress by pressing
lightly on the outer edge of the diamond wheel.
When feeding water during cutting
CAUTION:
When using a wet-type diamond
wheel, always feed water during cutting.
Connect the tool to the water supply and turn the cock
in the direction of the arrow as illustrated. Adjust the
position of the cock to obtain a gentle flow of water.
► Fig.17: 1. Cock
CAUTION:
When feeding water, always keep
the tool head lower than the tool body to prevent
water entering into the tool mechanism. Failure to
do so may cause electric shock.
► Fig.18

MAINTENANCE

CAUTION:
Always be sure that the tool is
switched off and the battery cartridge is removed before
attempting to perform inspection or maintenance.
NOTICE:
Never use gasoline, benzine, thinner, alcohol
or the like. Discoloration, deformation or cracks may result.
To maintain product SAFETY and RELIABILITY,
repairs, any other maintenance or adjustment should
be performed by Makita Authorized or Factory Service
Centers, always using Makita replacement parts.
Cleaning the tool
After each use, remove the battery cartridge and the wheel
and then clean dust, dirt or metal chips accumulated inside the
wheel guard. Clean the tool body by wiping off dust, dirt with a
dry cloth or one dipped in soapy water and wrung out. Use a
dry cloth to wipe the dirt off the lens of the lamp. Be careful not
to scratch the lens of lamp, or it may lower the illumination.

Cleaning the air vent
Regularly clean the tool's air vents or whenever the
vents start to become obstructed.

Changing the V-belt
1. Remove the battery cartridge and the wheel.
2.
Loosen the hex socket bolts using the hex wrench
and then remove the cover .

3. While twisting the V-belt inside, turn the bolt on the
pulley (large) clockwise using the box wrench.
The V-belt will deviate from the track and come off as
you turn the bolt.

NOTICE:
Never turn the box wrench counter-
clockwise. Doing so loosen the bolt on the pulley
(large) and result in poor performance.
