PRIOR TO OPERATION
1. Power source
Ensure that the power source to be utilized conforms
to the power requirements specified on the product
nameplate.
2. Power switch
Ensure that the power switch is in the OFF position.
If the plug is connected to a power receptacle while
the power switch is in the ON position, the power
tool will start operating immediately, which could
cause a serious accident.
3. Extension cord
When the work area is removed from the power
source, use an extension cord of sufficient thickness
and rated capacity. The extension cord should be
kept as short as practicable.
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,
Fig. 2)
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.
[Installing and adjusting the dust collection cover]
Open the lever and insert the locating pin of dust
collection cover, bringing it into line with the across
flats of packing ground.
Then, turn the dust collection cover to a desired
position (for use).
Close the lever and fix it. If and when required, carry
out adjustments by tightening or loosening the screw.
If the lever does not move smoothly, apply some
lubricating oil to the sliding section between the set
piece and the lever.
Fasten the dust collection cover at the position where
the across flats of the dust collection cover
positioning pin and packing ground are aligned (the
position where the dust collection cover is inserted),
but do not use it.
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. 3)
Lowering the wing nut will loosen and raising it will
tighten.
Loosening the wing nut and moving the base 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. 4)
(2) Install the dust collector hose for the power tool in
the accessory adaptor. (Fig. 4)
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) Loosen the knob nut and remove the cover (B).
(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. 5)
(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. Switch operation
Switch ON: Push the locking button forward and
then press the switch lever.
Switch OFF: Press and release the switch lever.
3. 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.
