Check grinding tools before using. The grinding tool must be
mounted properly and be able to move freely. Carry out a test run
for at least one minute with no load. Do not use damaged, out‐of‐
centre or vibrating grinding tools. Damaged grinding tools can burst
and cause injuries.
Operate the power tool with both hands.
Switch the power tool ON when holding it above the surface to be
grinded. Let the diamond grinding tool reach is maximum no‐load
speed before it makes contact with the surface.
Move the power tool with a circular motion or alternately in length
and crosswise direction over the work piece/surface applying
moderate pressure. When the rotational speed drops, apply less
pressure. Make sure the power tool reaches its maximum no‐load
speed before it makes contact with the surface again.
The guard and extraction hood is equipped with a removable
forebody [2]. Especially to grind the floor near to walls.
Only remove the forebody in exceptional situations. Without the
forebody the operator isn't fully protected against flying fragments
and the rotating diamond grinding tool.
Avoid any contact with the diamond grinding tool. A dismounted
forebody increases the risk of the diamond grinding tool contacting
limbs, clothing and cables.
Pull the mains plug of the power tool from the socket, before any
dismounting or mounting the forebody of the guard and extraction
hood!
Dismount the forebody by pressing the locking and moving the
forebody in the stated direction.
Mount the forebody by pushing it to its original position.
5. SERVICE & MAINTENANCE
Pull the mains plug of the power tool from the socket, before any
work on the machine itself!
For safe and proper working, always keep the machine and
ventilation slots clean.
A blunt diamond grinding tool can be reground by briefly grinding
abrasive material (e.g. lime‐sand brick).
Changing the Brush Collar
To ensure optimal dust extraction, directly change a worn brush
collar [3].
Pull the brush collar (if necessary with aid of a screwdriver) gently
out of the housing of the guard and extraction hood.
Push a new brush collar carefully into the housing, reaching the full
depth. Make sure the brush collar doesn't extends the guard and
extraction hood, so the forebody can be dismounted and mounted
without problems.
6. SAFETY WARNINGS
GENERAL POWER TOOL SAFETY WARNINGS
WARNING: Read all safety warnings and all
instructions. Failure to follow the warnings and
instructions may result in electric shock, fire and/or
serious injury.
Save all warnings and instructions for future reference.
The term "power tool" in the warnings refers to your mains‐operated
(corded) power tool or battery‐operated (cordless) power tool.
1) Work area safety
a) Keep work area clean and well lit. Cluttered or dark areas invite
accidents.
b) Do not operate power tools in explosive atmospheres, such as in
the presence of flammable liquids, gases or dust. Power tools create
sparks which may ignite the dust or fumes.
c) Keep children and bystanders away while operating a power
tool. Distractions can cause you to lose control.
2) Electrical safety
a) Power tool plugs must match the outlet. Never modify the plug
in any way. Do not use any adapter plugs with earthed(grounded)
power tools. Unmodified plugs and matching outlets will reduce risk
of electric shock.
b) 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.
c) Do not expose power tools to rain or wet conditions. Water
entering a power tool will increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying, pulling or
unplugging the power tool. Keep cord away from heat, oil, sharp
edges and moving parts. Damaged or entangled cords increase the
risk of electric shock.
e) When operating a power tool outdoors, use an extension cord
suitable for outdoor use. Use of a cord suitable for outdoor use
reduces the risk of electric shock.
f) If operating a power tool in a damp location is unavoidable, use a
residual current device (RCD) protected supply. Use of an RCD
reduces the risk of electric shock.
3) Personal safety
a) Stay alert, watch what you are doing and use common sense
when operating a power tool. Do not use a power tool while you
are tired or under the influence of drugs, alcohol or medication. A
moment of inattention while operating power tools may result in
serious personal injury.
