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. (Fig. 31)

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. 32)

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. 33)

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.
