Kerf Board; Maintaining Maximum Cutting Capacity; Adjusting Miter Angle; Blade Guard - Makita LS1040 Instruction Manual

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.7
When lowering the handle, the blade guard rises
automatically. The guard is spring loaded so it returns to
its original position when the cut is completed and the
handle is raised. NEVER DEFEAT OR REMOVE THE
BLADE GUARD OR THE SPRING WHICH ATTACHES
TO THE GUARD.
In the interest of your personal safety, always maintain
the blade guard in good condition. Any irregular
operation of the blade guard should be corrected
immediately. Check to assure spring loaded return
action of guard. NEVER USE THE TOOL IF THE
BLADE GUARD OR
FAULTY OR REMOVED. DOING SO IS HIGHLY
DANGEROUS AND
PERSONAL INJURY.
If the see-through blade guard 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
guard carefully with a damp cloth. Do not use solvents
or any petroleum-based cleaners on the plastic guard.
If the blade guard is especially dirty and vision through
the guard is impaired, 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
blade guard and center cover. With the blade guard so
positioned, cleaning can be more completely and
efficiently accomplished. When cleaning is complete,
reverse procedure above and secure bolt. Do not
remove spring holding blade guard. If guard becomes
discolored through age or UV light exposure, contact a
Makita service center for a new guard. DO NOT
DEFEAT OR REMOVE GUARD.

Kerf board

Fig.9
This tool is provided with the kerf board in the turn base
to minimize tearing on the exit side of a cut. If the kerf
groove has not yet been cut in the kerf board by the
factory, you should cut the groove before actually using
the tool to cut a workpiece. Switch on the tool and lower
the blade gently to cut a groove in the kerf board.
SPRING ARE DAMAGED,
CAN CAUSE SERIOUS

Maintaining maximum cutting capacity

Fig.10
Fig.11
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:
First, unplug the tool. Lower the handle completely. Use
the socket wrench to turn the adjusting bolt 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.12
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
Fig.13
Fig.14
To adjust the bevel angle, loosen the lever at the rear of
the tool counterclockwise.
Push the handle to the left to tilt the saw blade until the
pointer points to the desired angle on the bevel scale.
Then tighten the lever clockwise firmly to secure the
arm.
CAUTION:
When tilting the saw blade, be sure to raise the
•
handle fully.
After changing the bevel angle, always secure the
•
arm by tightening the lever clockwise.
