Cutting Operation - Makita HS009G Instruction Manual

Connecting a vacuum cleaner
Optional accessory
When you wish to perform clean cutting operation,
connect a Makita vacuum cleaner to your tool. Connect
a hose of the vacuum cleaner to the dust nozzle using
the front cuff 24.

Adjusting angle of dust nozzle
The angle of the dust nozzle can be adjusted by rotating
the dust nozzle.
When operating the tool without connecting a vacuum
cleaner, bring the dust nozzle downward to prevent the
operator from being exposed to sawdust.
When operating the tool with connecting a vacuum
cleaner, bring the dust nozzle upward to keep the hose
of the vacuum cleaner from getting caught in the work-
piece or the guide rail.

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
• Mineral contained plastic
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.
Do not use the tool without the sub base unless when
using the guide rail.
CAUTION:
When cutting plastic materials,
avoid melting it by overheating of the blade tip.
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 removing 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.28
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.
To get clean cuts, keep your sawing line straight and
your speed of advance uniform. If the cut fails to prop-
erly follow your intended cut line, do not attempt to turn
or force the tool back to the cut line. Doing so may bind
the circular saw blade and lead to dangerous kickback
and possible serious injury. Release switch, wait for cir-
cular saw blade to stop and then withdraw tool. Realign
tool on new cut line, and start cut again. Attempt to
avoid positioning which exposes operator to chips and
wood dust being ejected from saw. Use eye protection
to help avoid injury.
NOTE: When making a miter cuts etc., sometimes
the lower guard does not move easily. At that time,
use the retracting lever to raise the lower guard for
starting cut and as soon as blade enters the material,
release the retracting lever.

Sub base (Guide rule)
CAUTION:
Make sure that the sub base (guide
rule) is securely installed in the correct position
before use. Improper attachment may cause danger-
ous kickback.
By using the sub base as a guide rule, you can perform
extra-accurate straight cuts. Loosen the clamping
screws and slide the sub base out from the tool then
insert it upside down.
► Fig.30: 1. Clamping screw 2. Sub base
Simply slide the fence of the sub base snugly against
the side of the workpiece and secure it in position with
the clamping screws. It also makes repeated cuts of
uniform width possible.
