Cutting Operation - Makita HS012G Instruction Manual

WARNING:
BE SURE TO TIGHTEN THE HEX
BOLT SECURELY. Also be careful not to tighten
the bolt forcibly. Slipping your hand from the hex
wrench can cause a personal injury.
WARNING:
Make sure that the protrusion "a"
on the inner flange that is positioned outside fits
into the saw blade hole "a" perfectly. Mounting the
blade on the wrong side can result in the dangerous
vibration.
For tool with the inner flange for a
15.88 mm hole-diameter saw blade
(country specific)
Mount the inner flange with its recessed side facing
outward onto the mounting shaft and then place circu-
lar saw blade (with the ring attached if needed), outer
flange and hex bolt.

WARNING:
BE SURE TO TIGHTEN THE HEX
BOLT SECURELY. Also be careful not to tighten
the bolt forcibly. Slipping your hand from the hex
wrench can cause a personal injury.
WARNING:
If the ring is needed to mount the
blade onto the spindle, always be sure that the
correct ring for the blade's arbor hole you intend
to use is installed between the inner and the outer
flanges. Use of the incorrect arbor hole ring may
result in the improper mounting of the blade causing
blade movement and severe vibration resulting in
possible loss of control during operation and in seri-
ous personal injury.
Removing circular saw blade
1. Loosen the lever on the depth guide and move the
base down.
2. Press the shaft lock fully so that the mounting
shaft cannot revolve and use the hex wrench to loosen
the hex bolt. Then remove the hex bolt, outer flange,
circular saw blade and ring (country specific).
3. Install outer flange and hex bolt again. Press the
shaft lock and tighten the hex bolt.
Blade guard cleaning
When changing the circular saw blade, make sure to
also clean the upper and lower blade guards of accu-
mulated sawdust as discussed in the Maintenance
section. Such efforts do not replace the need to check
lower guard operation before each use.
Connecting a vacuum cleaner
When you wish to perform clean cutting operation,
connect a Makita vacuum cleaner to your tool.
Install the dust nozzle on the tool using the screw.

Connect a hose of the vacuum cleaner to the dust noz-
zle using the front cuff 24 (optional accessory).

OPERATION
This tool is intended to cut wood products. With appro-
priate Makita genuine circular saw blades, following
materials can also be sawed:
• Aluminum products
Refer to our website or contact your local Makita dealer for the
correct circular saw blades to be used for the material to be cut.
Checking blade guard function
Remove the battery cartridge.
Set the bevel angle to 0°, and then retract the lower
guard manually to the end and release it. The lower
guard is properly functioning if;
— it is retracted above the base without any hin-
drance and;
— it automatically returns and contacts with the stopper.

If the lower guard is not functioning properly, check if saw
dust is accumulated inside of the upper and lower guards. If
the lower guard is not functioning properly even after remov-
ing dust, have your tool serviced at a Makita service center.

Cutting operation

CAUTION:
Wear dust mask when performing
cutting operation.
CAUTION:
Be sure to move the tool forward
in a straight line gently. Forcing or twisting the tool
will result in overheating the motor and dangerous
kickback, possibly causing severe injury.
NOTE: When the battery cartridge temperature is
low, the tool may not work to its full capacity. At this
time, for example, use the tool for a light-duty cut for
a while until the battery cartridge warms up as high
as room temperature. Then, the tool can work to its
full capacity.
► Fig.27
Hold the tool firmly. The tool is provided with both a front
grip and rear handle. Use both to best grasp the tool.
If both hands are holding saw, they cannot be cut by
the circular saw blade. Set the base on the workpiece
to be cut without the circular saw blade making any
contact. Then turn the tool on and wait until the circular
saw blade attains full speed. Now simply move the tool
forward over the workpiece surface, keeping it flat and
advancing smoothly until the sawing is completed.
