Cutting Operation - Makita DHS901 Betriebsanleitung

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 CLOCKWISE 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.
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
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.
CAUTION:
When cutting plastic materials,
avoid melting it by overheating of the blade tip.
Checking blade guard function
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 hindrance 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 tem-
perature. 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.
