OPERATION INSTRUCTIONS

1. Use specified voltage: The tool should not be operated on a power line which exceeds

10% of the voltage indicated on the nameplate.

2. Inspect the tool before each use:

The grinding wheel must be inspected cafefully before

operating. Do not use the grinding wheel if there is any breakage or cracks. After

assembling the wheel, run the wheel idle for one minute to see if it is safe to use. Then

check if all the moving parts are running smoothly without abnormal noise or heavy

sparks from the commutator.

3. A

void overloading the tool: Do not apply too much pressure on the tool while grinding in

a straight or slanted line. If the speed drops abnormally, the pressure should be

decreased immediately. When the tool stops abruptly or is jammed, cut the power

supply at once.

4. Replace the carbon brushes in time:

Worn out brushes should be replaced (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 even burn the armature.

5. The tool must not be used in the following cases: If there is any breakage in the

insulation of the power cord or the cord guard. If a crack or imperfect contact of the

switch, plug and socket and faults such as discontinuous running, heavy sparking, etc.

should occur, stop using the tool at once and have it repaired. Do not use until it is

repaired.

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.

7. Use the tool with care: Handle the tool with care to avoid being bumped and prevent the

wheel iron from freezing or from becoming damp.

TECHINCAL SPECIFICATIONS

Grease the tool frequently

Grease can be volatilized and therefore the grease in the gearbox should be kept clean,

replenish or renew as needed.

Frequent inspection and maintenance

The tool should be inspected and maintained frequently. Check and make sure the power

cord, internal wires, plug and switch are in good condition. Make sure the insulation

resistance is within normal limits, the brush holders are not loose and the contact between

the brushes and the commutator are good, and that there is no short-circuit or breakage

of the armature and stator windings. Check the grinding wheel, bearings and driving parts

also.

Keep every disassembled part and replace parts with the same ones

While disassembling the tool, care must be taken to keep disassembled parts including

insulating sheets and bushes, etc. Damaged parts must be replaced with identical ones.

Alternative materials with features not as good as the original ones or parts not in

accordance with the original specifications must not be used.

Matters needing attention for assembly:

1. Be sure that all the parts are assembled to their original positions and especially do not

leave out any insulation sheets or bushes.

2. Check and see if the direction of rotation of the protruded shaft corresponds to that

marked on the head enclosure (facing the protruded shaft, you can see it rotating

clockwise).

Pay attention to insulation resistance

After having used the tool for a long time or it is used in moist conditions, the tool should

be tested before use for the insulation resistance between the winding and the casing with

a 500V megger. Should the insulation resistance be less than 7 megger, the winding must

be cooled and dried.

The tool must be well kept

The tool must be kept in an environement where the air is dry, clean and free from

corrosive vapour and in a place out of the reach of children.

MAINTENANCE

Please read and understand instructions before plugging tool.

1. Keep work area clean:

The work area should always be kept in order and properly lit. It

is dangerous to scatter things on the ground.

2. Proper posture and suitable clothing:

Concentrate on your work, keep your footing and

maintain your body balance. Work in suitable clothing and always wear safety goggles.

Do not wear gloves, loose clothing, neckties or jewelry.

3. Keep unauthorized people away:

Except for the people concerned, keep unauthorized

people away.

4. Use specified grinding wheel:

The wheel used by the grinder must be reinforced fibre

resin, with a safety linear velocity not lower than 80 meters per second. If the wheel

has been kept for more than one year, a rotational strength test should be performed

before use.

5. Pay attention to the wheel guard:

This wheel guard is an important part of the tool to

ensure safety. Do not operate the tool when the wheel guard has been dismantled. If

a substitute is to be used, it should be a steel plate or material with equal strength,

whereas brittle materials are strictly prohibited. The opening angle of the guard should

not be more than 180 degrees.

6. Places prohibiting the use of the tool:

The tool must not be used in specific

environements such as environements with moisture, heat, rain or snow or in a place

with explosive gas or corrosive vapours.

7. Proper use of the plug:

Do not change the plug and never insert naked wires directly

into a socket.

8. Proper use of the power cord:

The power cord should not be lengthened or changed.

The tool should not be carried by the power cord. It should not come in contact with

any heat source or oil and should be protected from being scraped, cut or jammed.

9. Unplugging the tool:

The tool should be unplugged after each use or before servicing

(changing parts or wheel). Do not unplug the tool by pulling on the power cord.

10. Prevent the tool from starting unexpectedly:

Before putting the plug into a socket, make

sure the switch is in the OFF position. When the plug is still connected to the power

source, do not carry the tool with your finger pressing on the trigger of the switch.
