GENERAL SAFETY INSTRUCTIONS FOR
ELECTRIC TOOLS
This device is exclusively for private use! It is
not fit for commercial use!
WARNING! Read all instructions. Failure
to follow all instructions listed below may
result in electric shock, fire and/or serious
injuries: SAVE THESE INSTRUCTIONS!
1. WORK AREA
• Keep work area clean and well lit. Cluttered
and dark areas invite accidents.
• Do not operate machines in explosive atmos-
pheres, such as in the presence of flammable
liquids, gases or dust. Machines create sparks
which may ignite the dust or fumes.
• Keep children and bystanders away while
operating a machine. Distractions can cause
you to lose control.
2. ELECTRICAL SAFETY
• Machine plugs must match the outlet. Never
modify the plug in any way. Do not use
any adapter plugs with earthed (grounded)
machines. Unmodified plugs and matching
outlets will reduce risk of electric shock.
• Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges
and refrigerators. There is an increased risk
of electric shock if your body is earthed or
grounded.
• Do not expose machines to rain or wet condi-
tions. Water entering a machine will increase
the risk of electric shock.
• Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the machine.
Keep cord away from heat, oil, sharp edges
or moving parts. Damaged or entangled cords
increase the risk of electric shock.
• When operating a machine outdoors, use an
extension cord suitable for outdoor use. Use
of a cord suitable for outdoor use reduces the
risk of electric shock.
3. PERSONAL SAFETY
• Stay alert, Watch what you are doing and use
common sense when operating a machine. Do
not use a machine while you are tired or under
the influence of drugs, alcohol or medication. A
moment of inattention while operating machines
may result in serious personal injury.
• Use safety equipment. Always wear eye pro-
tection. Safety equipment such as dust mark,
non-skid safety shoes, hard hat, or hearing
protection used for appropriate conditions will
reduce personal injuries.
• Avoid accidental starting. Ensure the switch is
in the off position before plugging in. Carrying
machines with your finger on the switch or
plugging in machines that have the switch on
invites accidents.
• Remove any adjusting key or wrench before
turning the machine on. A wrench or a key left
attached to a rotating part of the machine may
result in personal injury.
• Do not overreach. Keep proper footing and
balance at all times. This enables better con-
trol of the machine in unexpected situations.
• Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing and gloves
away from moving parts. Loose clothes, jewel-
lery or long hair can be caught in moving parts.
• If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used. Use of
these devices can reduce dust related hazards.
4. MACHINE USE AND CARE
• Do not force the machine. Use the correct
machine for your application. The correct
machine will do the job better and safer at the
rate for which it was designed.
• Do not use the machine if the switch does not
turn it on and off. Any machine that can not be
controlled with the switch is dangerous and
must be repaired.
• Disconnect the plug from the power source
before making any adjustments, changing
accessories, or storing machines. Such pre-
ventive safety measures reduce the risk of
starting the machine accidentally.
• Store idle machines out of the reach children
and do not allow persons unfamiliar with the
machine or these instructions to operate the
machine. Machines are dangerous in the
hands of untrained users.
• Maintain machines. Check for misalignment
or binding of moving parts, breakage of parts
and any other condition that may affect the
machines operation. If damaged, have the
machine repaired before use. Many accidents
are caused by poorly maintained machines.
• Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
• Use the machine, accessories and tool bits
etc., in accordance with these instructions and
in the manner intended for the particular type
of machine, taking into account the working
conditions and the work to be performed. Use
of the machine for operations different from
intended could result in a hazardous situation.
5. SERVICE
Have your machine serviced by a qualified
repair person using only identical replacement
parts. This will ensure that the safety of the
machine is maintained.
SPECIAL SAFETY INSTRUCTIONS
• Do not use the machine without the protective
cover! Ensure that this is fitted correctly!
• Ensure that the wheel dimensions are compat-
ible with the grinder.
• Check whether the mounting flanges and the
disk have been inserted correctly and are not
damaged!
• Ensure that the speed of the machine is
suitable for the accessories. Allow a newly
mounted abrasive wheel to run without a load
for at least thirty seconds! Please keep the
safety instructions in a safe place!
• Please ensure that the voltage of the mains
power supply corresponds to that stated on the
type plate. The tool is equipped with a two-pole
lead and plug!
• Check that the work piece is properly sup-
ported.
• Do not use cutting off wheel for side grinding.
• Ensure that sparks resulting from use do not
create a hazard e.g. do not hit persons, or
ignite flammable substances.
• Always use protective safety glasses and
hearing protectors, use other personal pro-
tective equipment such as gloves, apron and
helmet when necessary.
• Ensure that ventilation opening are kept clear
when working in dusty conditions. If it should
become necessary to clear dust, first disconnect
the tool from the mains supply(use non metallic
objects) and avoid damaging internal parts.
• Only use a suitable extension cable when this
is absolutely necessary! The use of an unsuit-
able extension cable carries with it the danger
of fire or an electric shock! If an extension
cable has to be used, ensure that it is correctly
wired and in good condition!
• Your machine is double insulated. This means
that two completely independent types of insu-
lation prevent you from coming into contact
with live metal parts. This measure represents
a high degree of protection against an electric
shock.
Hearing protection
In case of a sound pressure greater than
85.0 dB(A) wear hearing protection to avoid
damage to your hearing!
BEFORE INITIAL USE
Mounting the side handle
During operation, keep one hand on the housing
handle (5) and the other on the side handle (3). In
order to mount the side handle, screw it into the
screw hole of the gear box (4)

Correct fitting of the protective device
Ensure that the protective cover (6) is fitted cor-
rectly and that the fixing screws have been tight-
ened! Before tightening the fixing screws, turn
the on and off switch (1) to the (0) position and
remove the mains plug!
Grinding and surface processing
In order to grind surfaces you should use a coarse
abrasive disk with a sunken centre. You can use
abrasive disks with diameter of 115mm. The maxi-
mum thickness is 6 mm.
Cutting metal
In order to cut rods, tubes and metal parts you
should use a cutting-off wheel. You can use
wheels with diameter of 115mm. The maximum
thickness in this case is 3 mm.
Cutting stone material
When cutting stone material you should use a
flat cutting off wheel. You can use wheels with
diameter of 115mm. Always approach the job at
the same angle at which you would like to cut.
Maintain this angle during cutting and do not exert
any side pressure on the wheel.
Inserting the wheels/ disks
Please proceed as follows when inserting the
wheel/disk:
1. Before mounting, remove the mains plug from
the socket and move the on and off switch (1)
to position 0! Ensure that the protective device
is correctly installed.
2. Place the internal flange (10) on the drive shaft
(2). Ensure that it is in contact with the two flat
areas.
3. Now place the abrasive disk on the drive shaft
(2) and the internal flange (10). Ensure that it
is correctly in place.
4. Now attach the external flange with the thread
(9), ensuring that it is facing the rightdirection
according to the type of disk/wheel used. In
the case of abrasive I disks, the flange (9) is
inserted with the higher side pointing towards
the disk. In the case of cutting off wheels, the
flange (9) is inserted with the flat side pointing
towards the wheel5. Depress and hold the lock
button (7) so that cannot turn and then tighten
the external flange (9) with the external flange
spanner (8).
Flange arrangement
Check the Fig.2-4 for correct arrangement:
• when using a depressed - centre or straight
grinding wheel. (Fig. 2)
• when using a depressed - straight grinding
wheel. (Fig. 4)
• when using a depressed - centre grinding
wheel. (Fig. 5)
Abrasive Disks
• Ensure that the speed to which the machine is
set is sufficient for the accessories chosen.
• Use only abrasive disks with a diameter of
115mm!
• Before mounting the disk, remove the mains
plug from the socket and push the on and off
switch (1) to position 0!
1 Place the internal flange (10) on to the drive
shaft (2).
2. Place the abrasive disk on the drive shaft (2)
and ensure that it is correctly in place.
3. Attach the external flange with the thread (9)
and tighten it as described above with the
external flange spanner (8).
NOTE: Expect a “rain of sparks” when the disk
comes into contact with metal. While grinding,
always maintain the correct angle between the
disk and the working surface of 15°. This pro-
duces ideal results and avoids overloads.
Overload
The motor of your right angle grinding machine
may be damaged when overloaded. This results
from excessive working pressure over a pro-
longed period. Therefore you should not try to
accelerate your working speed by increasing
pressure on your machine. The abrasive disks
work more efficiently if only slight pressure is
exerted on the grinding machine, thus avoiding a
drop in the grinding speed.
MAINTENANCE
• The protective cover, air slits and motor hous-
ing should be kept as free of dirt and dust as
possible.
• Rub off the device with a clean cloth or use
compressed air at a low pressure to blow out
any dust or dirt. Excessive amounts of metal
dust may result in electricity from the internal
components being conducted on to exposed
metal parts!
• Do not subject the grinding machine to any
overload! Overloading will lead to a reduction
in the speed and performance and cause the
machine to overheat! If this should happen,
switch the grinding machine off and let it cool
down for approximately 30 minutes or to room
temperature!
NOTE: Turning off the grinding machine while it is
being subjected to a load will reduce the working
life of the operating switch!
CLEANING AND CARE
• Before cleaning the machine, remove the
mains plug from the socket and turn the on
and off switch (1) to position 0!
• For cleaning purposes, only use a slightly
damp but not wet cloth!
• Do not use any abrasive additives (petrol, tur-
pentine etc) as these may damage the plastic
housing!
• A mild soap is suitable for cleaning the
machine!
• Ensure that no moisture is allowed to get
inside the machine!
• After cleaning, wipe the machine with a dry
cloth!
