GRINDER OPERATION
1. Switching operation (Fig. 4)
(1) When throwing the switch lever to the ON side, power is applied; when throwing it to
the OFF side, power is switched off.
(2) After installing a new wheel, "test" the condition of the wheel by allowing the grinder to
operate for 180 seconds while the wheel is pointed away from you. Keep your hands
and body away from the wheel at all times.
2. Precautions on operation
(1) Lightly press the wheel to the material to be ground when grinding materials, high-
speed revolution is necessary. Use a hand grinder with high-speed revolution,
minimizing the pressing force.
(2) Dressing the wheel
After attaching a wheel, adjust deflection of the wheel center by using a dresser.
If the wheel center is eccentric, not only precise finishing cannot be achieved but also
grinder vibration increases, lowering grinder accuracy and durability.
A clogged or worn wheel will soil the finishing surface or lower grinding efficiency.
Occasionally dress the wheel by applying the dresser.
MAINTENANCE AND INSPECTION
WARNING:
Be sure to switch power OFF and disconnect the plug during maintenance and
inspection.
Using cracked, deformed or damaged wheels can lead to wheel breakage and resulting
serious inlury.
1. Inspecting the wheel
Ensure that the wheel is free of cracks and surface defects.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that they are properly tightened.
Should any of the screws be loose, retighten them immediately.
WARNING:
Using this portable grinder with loosened screws is extremely
dangerous.
