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. Avoid 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.
8. Use specified grinding wheel:
The wheel used by the grinder must be reinforced fibre
resin with depressed center and 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.
9. 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, where-
as brittle materials are strictly prohibited. The opening angle of the guard should not be
more than 180 degrees.
10. Places prohibiting the use of the tool:
The tool must not be used in specific
environments such as environements with moisture, heat, rain or snow or in a place
with explosive gas or corrosive vapours.
SAFETY INSTRUCTIONS
WARNING: YOUR ANGLE GRINDER MUST BE CONNECTED TO A 120V, 15-AMP
CIRCUIT. FAILURE TO CONNECT IN THIS WAY CAN RESULT IN INJURY FROM
SHOCK OR FIRE.
DOUBLE INSULATION TOOLS. Double Insulation is a design concept used in electric
power tools which eliminates the need for the three wire grounded power cord and
grounded power supply system. It is a recognized and approved system by Underwriter’s
Laboratories, CSA and Federal OSHA authorities.
IMPORTANT: Servicing of a tool with double insulation requires care and knowledge of the
system and should be performed only by a qualified service technician. WHEN
SERVICING, USE ONLY IDENTICAL REPLACEMENT PARTS OR THOSE
RECOMMENDED BY THE MANUFACTURER.
POLARIZED PLUGS: Your tool is equipped with a polarized plug (one blade is wider than
the other), this plug will fit in a polarized outlet only one way. If the plug does not fit fully in
the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install the
proper outlet. To reduce the risk of electric shock, do not change the plug in any way.
EXTENSION CORDS. The use of any extension cord will cause some loss of power. Use
the following chartto determine the minimum wire gauge (A.W.G-American Wire Gauge)
extension cord. Only use polarized extension
cords (one prong wider than the other) which
have 2-prong type plugs and 2-hole receptacles
which accept the tool’s plug.
For circuits that are further away from the
electrical circuit box, the wire gauge must be
increased proportionately in order to deliver
ample voltage to the angle grinder. Refer to
chart for wire length and size.

ASSEMBLY & OPERATION
INSTALLING GRINDING WHEEL &HANDLE
1) Press and hold down the spindle lock button (A)
Fig.1.
2) Remove the outer flange (B) Fig.1 with spanner
key (A) Fig.2 by turning counterclockwise.
3) Install 7/8” inner diameter grinding wheel (C)
Fig.1 against the inner flange (D).
4) Secure new grinding wheel with outer flange (B)
by pressing and holding spindle lock button and
using spanner key (A) Fig.2 to fix into place
(clockwise).
5) Install the handle on either side or on top of the
motor housing, based on the application or if you
are right or left handed.
6) If the safety guard (A) Fig.3 is not in the most
suitable position for the operation, it is
recommended to shift the position of the safety
guard by loosening screw (B), shift safety guard
position and secure with screw.
Warning! If you wish to install a wire brush, the
safety guard must be removed. Reinstall safety
guard once the wire brush operation is finished.
OPERATION
1) To turn the power on, firmly hold the angle
grinder with one hand. Use the other hand to
hold the side handle. Press the safety button (B)
Fig.4, then press the on/off trigger (A) Fig.4 to
start the angle grinder.
2) Use the side handle to help steady the tool and
assist movement.
3) Different grinding angles produce different
finishes. For rough stock, grind at a 30º angle.
For finishing operations, grind at a 15º angle.
4) Do not use excessive force, let the grinding
wheel do most of the work.
5) Once the grinding operation is finished, release
the trigger to stop the grinder, wait until the
grinding wheel has come to a complete stop
before you put the tool down.

INSPECTING/REPLACING CARBON BRUSHES
Warning! Only use identical replacement carbon brushes, both carbon brushes should be
replaced at the same time, normally after 50 hours of operation.
Unscrew and remove the two brush covers on each side of the motor housing. Take out
the carbon brushes and inspect them. If the wear of the carbon brushes has gone past the
limit mark, install new brushes. Reinstall all parts in reverse order.
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, 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.
Do not allow brake fluid, gasoline, petroleum-based products such as penetrating oils to
come in contact with plastic parts. They contain chemicals which can damage, weaken or
destroy the motor housing, thus compromising the intergrity of the double insulation.
Inspect mounting screws regularly, making sure they are properly tightened. Tighten all
loose screws before operating.
Service should be done by a qualified service technician using identical replacement parts.
