Maintenance; Optional Accessories; Adjusting The Depth Guide - Makita DHS900 Instruction Manual

MAINTENANCE

CAUTION:
Always be sure that the tool is
switched off and the battery cartridge is removed
before attempting to perform inspection or
maintenance.
CAUTION:
Clean out the upper and lower
guards to ensure there is no accumulated saw-
dust which may impede the operation of the lower
guarding system. A dirty guarding system may limit
the proper operation which could result in serious
personal injury. The most effective way to accomplish
this cleaning is with compressed air. If the dust is
being blown out of the guards, be sure the proper
eye and breathing protection is used.
CAUTION:
After each use, wipe off the saw
dust on the tool. Fine saw dust may come inside the
tool and cause malfunction or a fire.
NOTICE:
Never use gasoline, benzine, thinner,
alcohol or the like. Discoloration, deformation or
cracks may result.
To maintain product SAFETY and RELIABILITY,
repairs, any other maintenance or adjustment should
be performed by Makita Authorized or Factory Service
Centers, always using Makita replacement parts.
Adjusting 0°-cut or 45°-cut accuracy
NOTICE:
Do not engage the levers for -1° bevel
angle when adjusting 0°-cut accuracy.
NOTICE:
Do not engage the positive stopper for 22.5°
or 60° bevel angle when adjusting 45°-cut accuracy.
This adjustment has been made at the factory. But if it is
off, you can adjust it as the following procedure.
1.
Loosen the clamping screws on the front and rear
of the tool so that the bevel angle can be changed. Set
the positive stopper to 45° bevel angle position if you
are going to adjust 45°-cut accuracy.

2. Make the base perpendicular or 45° to the circular
saw blade using a triangular rule by turning the adjust-
ing screw with a hex wrench. You can also use a square
rule to adjust 0° angle.

3. Tighten the clamping screws and then make a test
cut to check if desired angle is obtained.

Adjusting the depth guide

If the base does not slide up or down smoothly, the
depth guide may have been tilted. You can adjust the
depth guide as follows:
1. Make the base perpendicular, and set the depth of
cut to the deepest.
2. Loosen the adjusting screws for the depth guide
with a hex wrench.
The depth guide automatically adjusts its position.
3. Tighten the adjusting screws for the depth guide.
4. Adjust the parallelism by referring to the section
for parallelism.

Adjusting the parallelism
CAUTION:
Keep the parallelism accurate.
Otherwise the circular saw blade may bite into the
guide rail and the damaged guide rail may cause an
injury.
This adjustment has been made at the factory. But if it is
off, you can adjust it as the following procedure.
1.
Set the tool to the maximum cutting depth.
2.
Make sure all levers and screws are tightened.
3. Loosen the screws shown in the figure.
4. While opening the lower guard, move the rear of
the base so that the distance A and B becomes equal.

5. Tighten the screws and make a test cut to check
the parallelism.
