flange (especially the installing surface) or the
lock nut. Damage to these parts could result in
wheel breakage.
18. Make sure the wheel is not contacting the
workpiece before the switch is turned on.
19. Before using the tool on an actual workpiece,
let it run for a while. Watch for vibration or
wobbling that could indicate poor installation

short-circuit breaker (30 mA) to assure
operator safety.
30. Do not use the tool on any materials
containing asbestos.
31. Do not use water or grinding lubricant.
32. Ensure that ventilation openings are kept clear
when working in dusty conditions. If it should

Never actuate the shaft lock when the spindle is
•
moving. The tool may be damaged.
Press the shaft lock to prevent spindle rotation when
installing or removing accessories.
Sighting
Fig.2
There are notches on the front and rear of the base. This
is helpful for an operator to follow a straight cutting line.
Adjusting the grooving or cutting depth
Fig.3
The depth of grooving or cutting can be adjusted in the
range of 0 through 30 mm.
Loosen and move the clamping screw so that the pointer
points to your desired depth graduation on the scale.
Then tighten the clamping screw firmly.
Switch action
properly Fig.4
CAUTION:
Before plugging in the tool, always check to see
•
that the slide switch actuates properly and returns
to the "OFF" position when the rear of the slide
switch is depressed.
To start the tool, slide the slide switch toward the "I (ON)"
position. For continuous operation, press the front of the
slide switch to lock it.
To stop the tool, press the rear of the slide switch, then
slide it toward the "O (OFF)" position.
Electronic function
The tools equipped with electronic function are easy to
first
operate because of the following features.
Constant speed control
Electronic speed control for obtaining constant speed.
Possible to get fine finish, because the rotating speed is
kept constant even under load condition.
Soft start
Soft-start feature minimizes start-up shock, and makes
the tool start smoothly.
Overload protector
When the tool would be employed over the admissible
load, it will stop automatically to protect the motor and
wheel. When the load will come to the admissible level
again, the tool can be started automatically.
