Blade Guard - Makita LS004G Instruction Manual

Blade guard

WARNING:
Never defeat or remove the blade
guard or the spring which attaches to the guard.
An exposed blade as a result of defeated guarding
may result in serious personal injury during operation.
WARNING:
Never use the tool if the blade
guard or spring are damaged, faulty or removed.
Operation of the tool with a damaged, faulty or
removed guard may result in serious personal injury.
CAUTION:
Always maintain the blade guard
in good condition for safe operation. Stop the
operation immediately if there are any irregularity
of the blade guard. Check to assure spring loaded
return action of guard.
When lowering the handle, the blade guard raises
automatically. The guard is spring loaded so it returns to
its original position when the cut is completed and the
handle is raised.

Cleaning
If the transparent blade guard becomes dirty, or sawdust
adheres to it in such a way that the blade and/or workpiece
is no longer easily visible, remove the battery cartridge and
clean the guard carefully with a damp cloth. Do not use
solvents or any petroleum-based cleaners on the plastic
guard because this may cause damage to the guard.
Follow the step-by-step instructions listed on how to
prepare for cleaning.
1. Make sure that the tool is switched off and the
battery cartridge is removed.
2.
Turn the hex bolt counterclockwise using the
supplied hex wrench while holding the center cover.
3. Raise the blade guard and center cover.
4. When cleaning is complete, return the center
cover and tighten the hex bolt by performing the steps
above in reverse.
5.
Make sure to return the circular saw blade and center
cover to their original positions and tighten the hex bolt.

WARNING:
Do not remove spring holding
blade guard. If guard becomes damaged in course
of time or UV light exposure, contact a Makita ser-
vice center for replacement. DO NOT DEFEAT OR
REMOVE GUARD.
Positioning kerf board
This tool is provided with the kerf boards in the turn
base to minimize tearing on the exit side of a cut. The
kerf boards are factory adjusted so that the circular saw
blade does not contact the kerf boards. Before use,
adjust the kerf boards as follows:
1. Make sure to remove the battery cartridge. Then,
loosen all the screws (two each on left and right) secur-
ing the kerf boards.

NOTE: The rear screws can easily be loosened and
tightened by turning the turn base at an angle. Make
sure to raise the handle fully when turning the turn
base.
2. Re-tighten them only to the extent that the kerf
boards can still be easily moved by hand.
3. Lower the handle fully, then pull and turn the stop-
per pin to lock the handle in the lowered position.
4. Pull and turn the stopper pin on the slide pole to
allow the carriage sliding.

5. Pull the carriage toward you fully.
6. Adjust the kerf boards so that they just contact the
sides of the blade teeth.

NOTICE:
When changing bevel angles, be sure
to reposition the kerf boards appropriately.
NOTICE:
Always remove the upper guide fences
and vertical vise before positioning the kerf
boards for left or right bevel cut.
7.
Tighten the front screws (do not tighten firmly).
8. Push the carriage toward the guide fences fully
and then adjust the kerf boards so that they just contact
the sides of the blade teeth.
9. Tighten the rear screws (do not tighten firmly).
10. After adjusting the kerf boards, release the stop-
per pin for handle lock and raise the handle. Then
tighten all the screws securely.
NOTICE:
After setting the bevel angle, ensure
that the kerf boards are adjusted properly. Correct
adjustment of the kerf boards helps to provide proper
support of the workpiece and minimizing workpiece
tear out.
Maintaining maximum cutting
capacity
This tool is factory adjusted to provide the maximum
cutting capacity for a 260 mm saw blade.
When installing a new circular saw blade, always check
the lower limit position of the circular saw blade, and if
necessary, adjust it as follows:
1.
Remove the battery cartridge. Then turn the stop-
per lever to engaged position.
► Fig.20: 1. Stopper lever
2. Push the carriage toward the guide fences fully
and lower the handle completely.

3.
Use the hex wrench to turn the adjusting bolt until
the circular saw blade comes slightly below the cross
section of the guide fences and the top surface of the
turn base.
