Replacing Carbon Brushes; After Use; Optional Accessories - Makita LS1440 Instruction Manual

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 follow-
ing 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.
