Operation - Makita DHS660 Instruction Manual

Removing or installing circular saw
blade
CAUTION:
Be sure the circular saw blade is
installed with teeth pointing up at the front of the
tool.
CAUTION:
Use only the Makita wrench to
install or remove the circular saw blade.
To remove the circular saw blade, press the shaft lock
fully so that the circular saw blade 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).

To install the circular saw blade, follow the removal
procedure in reverse.
For tool with the inner flange for
other than 15.88 mm hole-diameter
saw blade
The inner flange has a certain diameter protrusion on
one side of it and a different diameter protrusion on the
other side. Choose a correct side on which protrusion
fits into the saw blade hole perfectly. Mount the inner
flange onto the mounting shaft so that the correct side
of protrusion on the inner flange faces outward and then
place saw blade and outer flange.

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:
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:
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
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 as
shown in the figure.

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.30
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
