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 pre-
cise cutting. Do not tamper with it. Should looseness develop at the gear hous-
ing and arm connection, perform the following adjustment. Work the handle up
and down while tightening 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.
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.
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 Blade guard. Lubricate the sliding portions with tool
oil to prevent rust.
To maintain product SAFETY and RELIABILITY, repairs, any other mainte-
nance or adjustment should be performed by Makita Authorized Service Cent-
ers, always using Makita replacement parts.
