OPERATING INSTRUCTIONS
NOTE: Before using the tool, read the instruction book
carefully.
INTENDED USE
The machine is intended for cutting, roughing and brushing metal
and stone materials without using water. For cutting metal, a special
protection guard for cutting (not supplied) must be used.
ASSEMBLY
1. INSTALLING AND ADJUSTING AUXILIARY HANDLE (SEE FIG. A)
You have the option of two working positions to provide the safest
and most comfortable control of your angle grinder. The handle is
screwed clockwise into either hole on the sides of the gear case.
NOTE: This handle should be used at all times to maintain complete
control of the tool.
2. INSTALLING AND ADJUSTING THE WHEEL GUARD (SEE FIG.
B1-B3)
WARNING: For work with grinding or cutting discs, the
wheel guard must be mounted.
- Wheel Guard for Grinding
Align the projection on the guard with the indentation on the gear
box. Put the Wheel Guard for Grinding down firmly.
Loosen the clamping screw, if necessary.
Place the wheel guard with coded projection into the coded groove
on the spindle collar of the machine head and rotate to the required
position (working position).
Tighten clamping screw.
NOTE: The closed side of the wheel guard must always point to the
operator.
3. FITTING THE DISCS (NOT SUPPLIED)(SEE FIG. C1-C4)
Screw on the inner flange.
Pay attention to the dimensions of the grinding disc. The mounting
hole diameter must fit the inner flange without play.
Do not use reducers or adapters.
When using a diamond cutting disc, take care that the direction-
of-rotation arrow on the diamond cutting disc and the direction of
rotation of the machine (direction-of-rotation arrow on the machine
head) agree.
Place the disc on the tool spindle and inner flange.Ensure it is
correctly located. Fit the threaded outer flange making sure it is
facing in the correct direction for the type of disc fitted.
Screw on the outer flange.
4. SPINDLE LOCK BUTTON (SEE FIG. D)
Must only be used when changing a disc. Never press when the
disc is rotating!
OPERATION
1. ON/OFF SWITCH (SEE FIG. E)
To start the power tool, first press the back of on/off switch, then
push the on/off switch forward.
To lock the on/off switch, press the on/off switch down at the front
until it engages.
To switch off the power tool, release the on/off Switch or, if it is
locked, briefly push down the back of the on/off Switch and then
release it.
2. HAND GRIP AREAS (SEE FIG. F)
Always hold your angle grinder firmly with both hands when
operating.

3. TO USE THE GRINDER (SEE FIG. G)
ATTENTION: Do not switch the grinder on whilst the
disc is in contact with the workpiece. Allow the disc to
reach full speed before starting to grind.
Hold your angle grinder with one hand on the main handle and other
hand firmly around the auxiliary handle.
Always position the guard so that as much of the exposed disc as
possible is pointing away from you.
Be prepared for a stream of sparks when the disc touches the
metal.
For best tool control, material removal and minimum overloading,
maintain an angle between the disc and work surface of
approximately 15°-30° when grinding.
Use caution when working into corners as contact with the
intersecting surface may cause the grinder to jump or twist.
When grinding is complete allow the workpiece to cool. Do not touch
the hot surface.
4. CUTTING (SEE FIG. H)
WARNING! For cutting
wheel guard for cutting (not supplied).
When cutting, do not press, tilt or oscillate the tool.
Work with moderate feed, adapted to the material being cut.
Do not reduce the speed of running down cutting discs by applying
sideward pressure.
The direction in which the cutting is performed is important.
The tool must always work in an up-grinding motion.
Therefore, never move the tool in the other direction! Otherwise, the
danger exists of it being pushed uncontrolled out of the cut.
5. AUTO-STOP CARBON BRUSHES (SEE FIG. I)
Before any work on the machine itself, pull the mains plug.
When the resin insulating tip inside the carbon brush is exposed
to contact the commutator, it will automatically shut off the motor.
When this occurs, both carbon brushes should be replaced. Keep
the carbon brushes clean and free to slip in the holders. Both carbon
brushes should be replaced at the same time. Use only identical
carbon brushes.
6. OVERLOAD
Overloading will cause damage to the motor of your angle grinder.
This can happen if your angle grinder is subjected to heavy use for
prolonged periods of time.
Never attempt to exert too much pressure on your angle grinder to
speed up your work.
The abrasive discs operate more efficiently when light pressure is
exerted, thus avoiding a drop in the speed of your angle grinder.
If your angle grinder becomes too hot, run it no load for 2-3 minutes
until it has cooled to normal operation temperature.
7. POWER OUTAGE PROTECTION
When the power supply suddenly cuts off, the machine will stop.
When the power is turned on after a power outage, the machine
will not start by itself, you need to release the switch and restart
the machine.
WORKING HINTS FOR YOUR ANGLE GRINDER
1. Always start at no load to achieve maximum speed then start
working.
2. Do not force the disc to work faster, reducing the Disc's moving
speed means longer working time.
3. Always work with a 15-30 angle between disc and workpiece.
