SAW BLADE MOUNTING AND
DISMOUNTING
WARNING
● To prevent an accident or personal injury, always turn off
the trigger switch and disconnect the power plug from
the receptacle before removing or installing a saw blade.
If cutting work is done in a state where the 8 mm bolt is
not suffi ciently tightened, the 8 mm bolt can get loose,
the blade can come off , and the lower guard can get
damaged, resulting in injuries.
Also, check that the 8 mm bolts are properly tightened
before plugging the power plug into the receptacle.
● If the 8 mm bolts are attached or detached using tools
other than the 13 mm wrench (standard accessory),
excessive or improperly tightening occurs, resulting in
injury.
1. Dismounting the blade (Fig. 29-a, Fig. 29-b, Fig. 29-c
and Fig. 29-d)
(1) Unplug the power cord from the outlet.
(2) Raise the cutting head to the upright position and slide
the cutting head completely toward the rear of the unit
and tighten the slide securing knob.
(3) Push slightly on the blade guard locking lever and then
raise the lower guard to the uppermost position.
(4) While holding the lower guard, remove the cover plate
screw with a Phillips screwdriver.
(5) Rotate the cover plate to expose the 8 mm bolt.
(6) Place the blade end spanner over the 8 mm bolt.
(7) Locate the spindle lock on the motor.
(8) Press the spindle lock, holding it in fi rmly while turning
the blade clockwise. The spindle lock will then engage
and lock the arbor. Continue to hold the spindle lock,
while turning the spanner clockwise to loosen the
8 mm bolt.
(9) Remove the 8 mm bolt, washer (B) and the blade. Do not
remove the washer (A).
NOTE
○ If the spindle lock cannot be easily pressed in to lock the
spindle, turn the 8 mm bolt with 13 mm wrench (standard
accessory) while applying pressure on the spindle lock.
The saw blade spindle is locked when the spindle lock is
pressed inward.
○ Pay attention to the pieces removed, noting their position
and direction they face. Wipe the washer (B) clean from
any sawdust before installing a new blade.
WARNING
When mounting the saw blade, confi rm that the rotation
indicator mark on the saw blade and the rotation direction
of the lower guard (see Fig. 1) are properly matched.
CAUTION
● Confi rm that the spindle lock has returned to the retract
position after installing or removing the saw blade.
● Tighten the 8 mm bolt so it does not come loose during
operation.
Confi rm the 8 mm bolt has been properly tightened
before the power tool is started.
2. Mounting the saw blade
WARNING
Unplug the miter saw before changing/installing the
blade.
(1) Install a 216 mm blade with arbor, making sure the
rotation arrow on the blade matches the clockwise
rotation arrow on the lower guard, and the blade teeth
are pointing downward.
(2) Place washer (B) against the blade. Thread the 8 mm
bolt on arbor in a counterclockwise direction.
NOTE
Make sure the fl ats of the washers are engaged with the
fl ats on the arbor shaft. Also, the fl at side of the washer
must be placed against the blade.
(3) Place the blade spanner on the 8 mm bolt.
(4) Press the spindle lock, holding it in fi rmly while turning
the blade counterclockwise. When it engages, continue
to press the spindle lock in, while tightening the 8 mm
bolt securely.
(5) Rotate the cover plate back to its original position until
the slot in the cover plate engages with the hole of cover
plate screw.
While holding the lower guard at the uppermost position,
tighten the cover plate screw with a Phillips screwdriver.
(6) Lower the lower guard and verify that operation of the
guard and blade guard locking lever do not bind or stick.
(7) Be sure the spindle lock is released so the blade turns
freely.
CAUTION
Never attempt to install saw blades larger than 216 mm
in diameter.
Always install saw blades that are 216 mm in diameter or
less.
MAINTENANCE AND INSPECTION
WARNING
To avoid an accident or personal injury, always confi rm
that the trigger switch is turned OFF before performing
any maintenance or inspection of this tool.
Report to qualifi ed person as soon as possible, if you
discover the fault of machine including guards or blade
saw.
1. Inspecting the saw blade
Always replace the saw blade immediately upon the fi rst
sign of deterioration or damage.
A damaged saw blade can cause personal injury and
a worn saw blade can cause ineff ective operation and
possible overload to the motor.
CAUTION
Never use a dull saw blade. When a saw blade is dull,
its resistance to the hand pressure applied by the tool
handle tends to increase, making it unsafe to operate the
power tool.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that
they are properly tightened. Should any of the screws
be loose, re-tighten them immediately. Failure to do so
could result in serious hazard.
3. Inspecting the carbon brushes (Fig. 30)
Replace both carbon brushes when either has less than
6 mm length of carbon remaining, or if the spring or wire
is damaged or burned. To inspect or replace brushes,
fi rst unplug the saw. Then remove the brush cap on the
side of the motor. Remove the cap cautiously, because it
is springloaded. Then pull out the brush and replace.
Replace for the other side. To reassemble reverse the
procedure. The ears on the metal end of the assembly
go in the same hole the carbon part fi ts into. Tighten the
cap snugly, but do not overtighten.
NOTE
To reinstall the same brushes, fi rst make sure the
brushes go back in the way they came out. This will
avoid a break-in period that reduces motor performance
and increases wear.
4. Maintenance of the motor
The motor unit winding is the very "heart" of the power
tool. Exercise due care to ensure the winding does not
become damaged and/or wet with oil or water.
5. Replacing supply cord
If the supply cord of Tool is damaged, the Tool must be
returned to HiKOKI Authorized Service Center for the
cord to be replaced.
