Maintenance; Cleaning The Tool; Changing The V-Belt - Makita DCE090ZX2 Instruction Manual

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.
► Fig.17
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.

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.

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 accu-
mulated 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 strongly twisting the V-belt so that its inner
side faces up as shown in the figure, 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.
4.
Hook the new V-belt to the pulley (small). Put the
other end of the V-belt onto the pulley (large) so that
it is partially hooked on the forefront rail of the pulley.
(You don't have to hook the V-belt to all of the rails on
the pulley at this stage). After that, turn the bolt on the
pulley (large) clockwise using the box wrench.
The V-belt will get on the track as you turn the bolt.

Make sure that all the guides on the internal circle of the
V-belt fit into the rails on the pulleys. All the rails on the
pulley must support the guides on the V-belt. If there is
a rail which does not support the guide, the V-belt is not
properly installed.

5. Place the cover onto the tool and tighten the hex
socket bolts using the hex wrench.

NOTICE:
Make sure that the tube for water feed
is in the positions as shown in the figure before
attaching the cover.
