Tips for maintaining maximum battery life
1. Charge the battery cartridge before completely
discharged.
Always stop tool operation and charge the bat-
tery cartridge when you notice less tool power.
2. Never recharge a fully charged battery cartridge.
Overcharging shortens the battery service life.
3. Charge the battery cartridge with room tempera-
ture at 10°C – 40°C (50°F – 104°F). Let a hot bat-
tery cartridge cool down before charging it.
4.
Charge the Nickel Metal Hydride battery car-
tridge when you do not use it for more than six
months.

FUNCTIONAL DESCRIPTION

CAUTION:
• Always be sure that the tool is switched off and the bat-
tery cartridge is removed before adjusting or checking
function on the tool.
Installing or removing battery cartridge (Fig. 1)
• Always switch off the tool before installation or removal
of the battery cartridge.
• To remove the battery cartridge, withdraw it from the
tool while pushing the buttons on sides of the cartridge.
• To insert the battery cartridge, align the tongue on the
battery cartridge with the groove in the housing and slip
it into place. Always insert it all the way until it locks in
place with a little click. If not, it may accidentally fall out
of the tool, causing injury to you or someone around
you.
• Do not use force when inserting the battery cartridge. If
the cartridge does not slide in easily, it is not being
inserted correctly.
Adjusting the depth of cut (Fig. 2 & 3)
Loosen the clamp screw on the depth guide and move
the base up and down.
You can read the depth of cut by aligning the top of the
notch in the depth guide with the graduations on its right
side. (Note: This can be done for 0° bevel cutting only.)
At the desired depth of cut, secure the base by tightening
the clamping screw.
CAUTION:
• Use a shallow depth of cut when cutting thin workpiece
for cleaner, safer cuts.
• After adjusting the depth of cut, always tighten the
clamping screw securely.
Bevel cutting (Fig. 4)
Loosen the clamping screw on the bevel scale plate on
the front of the base. Set for the desired angle (0° – 45°)
by tilting accordingly, then tighten the clamping screw
securely.
CAUTION:
• After adjusting the depth of cut and bevel cutting angle,
be sure to tighten the clamping screw.
Sighting (Fig. 5)
For straight cuts, align the "A" position on the front of the
base with your cutting line. For 45° bevel cuts, align the
"B" position with it.

Switch action (Fig. 6)
CAUTION:
• Before inserting the battery cartridge into the tool,
always check to see that the switch trigger actuates
properly and returns to the "OFF" position when
released.
To prevent the switch trigger from being accidentally
pulled, a lock-off lever is provided.
To start the tool, slide the lock-off lever in the direction of
the arrow and pull the switch trigger. Release the switch
trigger to stop.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and the bat-
tery cartridge is removed before carrying out any work
on the tool.
Installing or removing diamond wheel (Fig. 7)
To install the wheel, first loosen the bolt with the hex
wrench and remove the bolt and the flange. Then mount
the wheel, the flange and the bolt. The wheel should be
mounted with the Makita name on the flange side.
Press the shaft lock so that the wheel cannot revolve.
Use the hex wrench to tighten the bolt securely.
To remove the wheel, follow the installation procedure in
reverse. (Fig. 8)
CAUTION:
• When installing the wheel, be sure to tighten the bolt
securely.
• Use only the Makita wrench to install or remove the
wheel.
Hex wrench storage (Fig. 9)
When not in use, store the hex wrench as shown in the
figure to keep it from being lost.
Installing water supply (Fig. 10)
Attach the tank holder on the tank. The tank holder
should be attached around the portion shown with the
dotted line. Tighten the screw (A) to the extent that the
tank can still turn within the tank holder.
Attach the tank holder onto the motor housing. Tighten
the screw (B) securely. (Fig. 11)
Connect the cap on the end of the polyvinyl tube to the
mouth of the tank. Turn the tank clockwise when making
the connection. Then tighten the screw (A) securely to
secure the tank. (Fig. 12)
CAUTION:
• If you find the polyvinyl tube is bent like a "V" or has
been strained excessively after installing the water sup-
ply, loosen the screw (B) and adjust the position of the
tank to alleviate the bent, pinched or strained condition.
Water supply (Fig. 13)
Remove the cap on the tank and fill through the hole.
Recap the tank. Be sure that the water cock is turned off
when filling the tank with water.
CAUTION:
• When filling the tank with water, be careful not to let the
tool get wet.
