OPERATION
3
1.
Use specified voltage: The tool should be operated on a power line, the voltage of which will not exceed
that specified voltage on the nameplate more than 10%.
OPERATING INSTRUCTIONS
2.
Inspect the tool before use: The grinding wheel must be inspected before use. After confirming everything
is in working order. After assembling the wheel idle for one minute to confirm everything is working properly.
3.
Avoid overloading the tool, do not apply too much pressure on the tool while cutting in a straight or slanted
line In case the rotational speed drops abnormally, the pressure should be decreased immediately. When the
tool stops abruptly or is blocked, the power supply should be cut off at once.
4.
Replace the carbon brushes in time. Worn out brushes should be replaced in time (both brushes should
be changed at the same time), or imperfect contact between the brushes and the commutator will result in
ring sparks which will damage the commutator or burn the armature.
5.
The tool must not be used in the following circumstances. If any insulation impairment breakage of the
power supply cord or cable guard, cracks or imperfect contact of the switch, plug and socket and faults such
as discontinuous running, heavy sparking etc should occur, stop using the tool and have it repaired at once.
6.
Always keep the tool clean. The ventilation passage of the tool should be kept clean and free from
obstruction and care should be taken to prevent iron chips or other foreign matters from entering passage.
Recondition immediately after use to keep the tool clean and in the best condition.
Make sure when using the tool, you maintain good balance. Wear suitable clothing and safety goggles.
Do not wear gloves or baggy clothes.
Use a specified grinding wheel. The wheel used by the grinder must be reinforced with fiber resin bond
and with a safety liner not lower than 80 meters per second. If the wheel has been kept for more than a
year the rotational strength test should be made before use.
Pay attention to the wheel guard. This wheel guard is an important part to ensure safety. Do not operate
the tool when the wheel guard has been dismantled. If a substitute should be used, it should be made of
steel plate or a material of equal strength. Brittle materials are strictly prohibited. The opening angle of the
guard should not be more than 180 degrees.
DO NOT use the tool is environments where moisture, heat or combustible materials are present.
The plug should be used properly. Do not change the plug and insert the naked wire directly in the socket.
DO NOT use the power cord indiscriminately. The cord should not be lengthened or changed. The cord
should not come into contact with a heat source and should be protected from beings scraped, cut or
jammed.
Prevent the tool from starting unexpectedly. When putting the plug into the socket, make sure the power
switch is in the OFF position. NEVER carry the tool with your finger pressing the trigger on the switch.
