FUNCTIONAL DESCRIPTION

CAUTION:
Always be sure that the tool is switched off and
•
unplugged before adjusting or checking function
on the tool.
Blade guard
Fig.6
CAUTION:
Make sure that the handle cannot be lowered
•
without pushing the lever nearby the handle to the
left.
Make sure that the lower blade guards A and B
•
dose not open unless the lever near the handle is
pushed at the topmost position of the handle.
When lowering the handle while pushing the lever to the
left, the lower blade guard A rises automatically. The
lower blade guard B rises as it contacts a workpiece.
The lower blade guards are spring loaded so it returns
to its original position when the cut is completed and the
handle is raised. The top blade guard falls flat on the top
surface after workpiece has passed under it. NEVER
DEFEAT OR REMOVE THE LOWER BLADE GUARDS,
THE SPRING WHICH ATTACHES TO THE LOWER
BLADE GUARD, OR THE TOP BLADE GUARD .
In the interest of your personal safety, always maintain
each blade guard in good condition. Any irregular
operation of the guards should be corrected immediately.
Check to assure spring loaded return action of the lower
blade guards. NEVER USE THE TOOL IF THE LOWER
BLADE GUARD, SPRING OR THE TOP BLADE
GUARD ARE DAMAGED, FAULTY OR REMOVED.
DOING SO IS HIGHLY DANGEROUS AND CAN
CAUSE SERIOUS PERSONAL INJURY.
If any of these see-through blade guards becomes dirty,
or sawdust adheres to it in such a way that the blade is
no longer easily visible, unplug the saw and clean the
guards carefully with a damp cloth. Do not use solvents
or any petroleum-based cleaners on the plastic guard.
If the lower blade guard A is especially dirty and vision
through the guard is impaired, proceed as follows. Fix
the top table at the fully elevated position, raise the
handle fully, push in fully the stopper pin with the handle
fully raised, and use the supplied socket wrench to
loosen the hex bolt holding the center cover. Loosen the
hex bolt by turning it counterclockwise and raise the
lower blade guard A and center cover while pushing the
lever to the left. With the lower blade guard A so
positioned, cleaning can be more completely and
efficiently accomplished. When cleaning is complete,
reverse procedure above and secure bolt.
In the same case for the top blade guard as above
stated, loosen the screw holding it with a screwdriver
and remove the top blade guard. After cleaning, always
reinstall it securely by tightening the screw to the extent
that the top blade guard moves smoothly up or down.
If any of these blade guards becomes discolored
through age or UV light exposure, contact a Makita
service center for a new guard. DO NOT DEFEAT OR
REMOVE GUARDS.

Maintaining maximum cutting capacity
Fig.8
Fig.9
This tool is factory adjusted to provide the maximum
cutting capacity for a 260 mm saw blade.
When installing a new blade, always check the lower
limit position of the blade and if necessary, adjust it as
follows:
CAUTION:
When making this adjustment, position the top
•
table at the lowest position after unplugging the
tool.
First, unplug the tool. Position the top table at the lowest
position. Lower the handle completely. Use the socket
wrench to turn the adjusting bolt that you can find below
in the biggest hole in the top table, until the periphery of
the blade extends slightly below the top surface of the
turn base at the point where the front face of the guide
fence meets the top surface of the turn base.
With the tool unplugged, rotate the blade by hand while
holding the handle all the way down to be sure that the
blade does not contact any part of the lower base. Re-
adjust slightly, if necessary.
CAUTION:
After installing a new blade, always be sure that
•
the blade does not contact any part of the lower
base when the handle is lowered completely.
Always do this with the tool unplugged.
Adjusting the miter angle
Fig.10
Loosen the grip by turning counterclockwise. Turn the
turn base while pressing down the lock lever. When you
have moved the grip to the position where the pointer
points to the desired angle on the miter scale, securely
tighten the grip clockwise.
CAUTION:
When turning the turn base, be sure to raise the
•
handle fully.
After changing the miter angle, always secure the
•
turn base by tightening the grip firmly.
Adjusting the bevel angle
