Carrying tool

Make sure that the tool is unplugged. Secure the turn
base at right miter angle fully by means of the grip. Lower
the handle fully and lock it in the lowered position by turn-
ing the handle latch to the locked position.

(Fig. 27)

Carry the tool by holding both sides of the tool base as
shown in the figure. If you remove the holders, dust bag,
etc., you can carry the tool more easily.

(Fig. 28)

CAUTION:
• Always secure all moving portions before carrying the

tool.

• Handle latch is for carrying and storage purposes only

and not for any cutting operations.

MAINTENANCE

CAUTION:
• Always be sure that the tool is switched off and

unplugged before attempting to perform inspection or
maintenance.

WARNING:
• Always be sure that the blade is sharp and clean for the

best and safest performance.

Adjusting the cutting angle

This tool is carefully adjusted and aligned at the factory,
but rough handling may have affected the alignment. If
your tool is not aligned properly, perform the following:
Loosen the grip which secures the turn base. Turn the
turn base so that the pointer points to 0° on the miter
scale. Then turn the turn base slightly clockwise and
counterclockwise to seat the turn base in the 0° miter
notch. (Leave as it is if the pointer does not point to 0°.)
Loosen the hex bolts securing the guide fence using the
socket wrench.

(Fig. 29)

Lower the handle fully and lock it in the lowered position
by turning the handle latch to the locked position. Square
the side of the blade with the face of the guide fence
using a triangular rule, try-square, etc. Then securely
tighten the hex bolts on the guide fence in the order from
the right side.

(Fig. 30)

Make sure that the pointer on the indication plate points
to 0° on the miter scale. If the pointer does not point to
0°, loosen the screws which secure the indication plate
and adjust it so that the pointer will point to 0°.

(Fig. 31)

Adjusting for smooth handle action

The hex lock nut which holds the gear housing and the
arm has been factory adjusted to assure smooth handle
action up and down and to guarantee precise cutting. Do
not tamper with it. Should looseness develop at the gear
housing and arm connection, perform the following
adjustment. Work the handle up and down while tighten-
ing the hex lock nut; the best position to tighten the hex
lock nut is just before the motor body weight is obvious.
After adjusting the hex lock nut, be sure that the handle
returns automatically to the initial, raised position from
any position. If the hex lock nut is too loose, the cutting
accuracy will be affected; if it is too tight, it will be hard to
work the handle up and down. Note that this is a self
locking nut. It is a special type that does not loosen in
normal use. It should not be overtightened or replaced
with other types of nuts.

Replacing carbon brushes

Remove and check the carbon brushes regularly.
Replace when they wear down to the limit mark. 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. 33)

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. 34)

After replacing brushes, plug in the tool and break in
brushes by running tool with no load for about 10 min-
utes. Then check the tool while running and electric
brake operation when releasing the switch trigger. If elec-
tric brake is not working well, ask your local Makita ser-
vice center for repair.

After use

• After use, wipe off chips and dust adhering to the tool

with a cloth or the like. Keep the blade guard clean
according to the directions in the previously covered
section titled “Blade guard”. Lubricate the sliding por-
tions with machine oil to prevent rust.

To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be per-
formed by Makita Authorized Service Centers, always
using Makita replacement parts.
