Installing Dust Collection Hose; Maintenance And Inspection - HIKOKI CM 5SB Mode D'emploi

4. Checking and installing the diamond wheel
Check the diamond wheel is a specified one and
is not cracked, broken or bent. Check the diamond
wheel is installed securely. For installation, refer to
"Installing/removing diamond wheel".
5. Fitting and adjusting the dust collection cover (Fig. 1)
The dust collection cover is a protective device to
prevent injury should the diamond wheel shatter
during operation. Ensure that the cover is properly
fitted and fastened before commencing cutting
operation. By slightly loosening the setting screw,
the dust collection cover can be turned and set at
any desired angle for maximum operational
effectiveness. Ensure that the setting screw is
thoroughly tightened after adjusting the dust
collection cover.
6. Confirm the spindle lock mechanism
Confirm that the spindle lock is disengaged by
pushing push button two or three times before
switching the power tool on (See Fig. 1).
7. Cutting depth adjustment (Fig. 2)
Lowering the wing nut will loosen and raising it will
tighten.
Loosening the wing nut and moving the slide guide
will allow adjustment of the cutting depth.
CAUTIONS
Leaving the wing nut loosened may result in injury.
Securely tighten the wing nut after adjusting the
cutting depth.

INSTALLING DUST COLLECTION HOSE

When cutting a material which generates cutting dust,
use the dust collection hose as follows:
(1) Remove the rubber cap and install the accessory
adaptor. (Fig. 3)
(2) Install the dust collection hose for the power tool
in the accessory adaptor. (Fig. 3)
CAUTION
Always install a rubber cap on the dust collection
adaptor when the dust collection hose is not used.
INSTALLING/REMOVING DIAMOND WHEEL
1. Installation
(1) Remove the cover (A).
(2) Wipe the cutting dust from the spindle and washers.
(3) Make sure the rotation direction of the diamond
wheel conforms to the direction indicated on the
gear case and install the diamond wheel as shown
in Fig. 1.
(4) Press the lock pin and secure the spindle. Tighten
the wheel nut adequately with the provided wrench.
(Fig. 1)
NOTE
Always use the provided wrench to secure the wheel
nut.
2. Removal
Remove the wheel nut with the provided wrench
and remove the diamond wheel. (Fig. 1)
CUTTING
1. Cutting procedures (Fig. 4)
(1) Place this tool on the material to be cut and align
the cutting line and the diamond wheel.
The cutting can be performed smoothly if you cut
straight ahead on the cutting line in the initial cut.
(2) Turn on the switch when the diamond wheel is not
touching the material to be cut.
2. Precautions immediately after finishing operation
After switching off the machine, do not put it down
until the depressed center wheel has come to a
complete stop. Apart from avoiding serious accidents,
this precaution will reduce the amount of dust and
swarf sucked into the machine.
CAUTION
Always check the diamond wheel before starting
work. Never use a diamond wheel which is cracked,
broken or bent.
Do not apply water or coolant to the diamond
wheel.
Start cutting only when diamond wheel reaches its
maximum speed.
If the diamond wheel seizes or there is any abnormal
noise, immediately turn the power off.
Never use the diamond wheel to cut zigzag or
curved lines. Never use the side surface of the
diamond wheel. Never use to perform inclination
cutting.
If excessive force is applied to the diamond wheel
to make it align with the cutting line during cutting,
this might not only overload the motor and cause
burn damage but may also overheat the diamond
wheel and shorten the service life.
Secure the workpiece. A workpiece clamped with
clamping devices or in a vice is held more securely
than by hand.
Take care not to allow the power cord to come into
contact with the diamond wheel during operation.
When the work is completed, turn the power off
and disconnect the power plug from the receptacle.

MAINTENANCE AND INSPECTION

1. Inspection the diamond wheel
A worn diamond wheel overloads the motor and
reduces working efficiency. Replace with a new one.
2. Diamond wheel clogging
The rate of wear of the diamond layer cutting edge
will vary depending on the type of material being
cut, the cutting speed, etc. In general, materials
which produce granular cutting particles may scrape
the bodying agent and hasten the wear of the
diamond layer. On the other hand, materials which
produce powdery cutting particles may cause
clogging of the diamond layer which will reduce
cutting efficiency. When clogging occurs, additional
force applied in an attempt to increase cutting speed
will sometime cause sparks to appear around the
circumference of the diamond wheel. In such a case,
stop using the cutter and carefully inspect the cutting
edge by rubbing it with your fingers. If the diamond
layer feels smooth (no roughness or abrasiveness),
it is clogged with dust and must be "dressed".
