See the warranty that accompanies the machine.
Safety regulations
• This machine may only be operated, repaired or in any other way handled by personnel who
have the requisite training and have read this manual.
• Only use this machine for grinding and polishing unhewn stone, terrazzo, concrete or any of
the other materials specified in this manual.
• Only use original tools and original spare parts in the machine. Failure to do so will nullify
the CE marking and warranty.
• Only lift the machine using the intended lifting bow. Do not lift the machine by the handle,
motor, chassis or other parts. Transport the machine securely mounted on a pallet wherever
possible.
• Always keep the machine in a dry and warm area when it is not being used. If this is not the
case, the machine could be damaged due to internal condensation.
• If the machine has to be stored in a cool place, it must be in a heated area at least two (2)
hours before use.
• Do not move the machine manually on an inclined surface. Even a gentle slope can gene-
rate rollng forces that cannot be checked by hand power alone.
• Do not use the machine on an inclined surface.
• Do not use the machine in environments where there is a risk of explosion or fire.
• Wear personal safety equipment such as boots with steel toe caps, goggles, protective glo-
ves and ear muffs.
• Check that all the phases are deenergised before starting the machine. Check using test
tools.
• Do not start the machine with the grinding head raised. Only start the grinder with the rota-
ting discs facing the floor and with the correct tools mounted.
• Do not start the machine without the splashguard mounted which seals between the grin-
ding head and the floor. Also ensure that the splashguard is in satisfactory condition.
• Fill the tank with cold water only.
• No chemicals may be added to the water. Chemicals may cause leakage resulting in danger
of electrical contact and injury.
• Observe caution when filling with water so as to avoid danger of electrical contact and injury.

6
• Only use the water tank for its intended purpose.
• Use a customised dust extractor when dry grinding, such as HTC D26, D30, D55 or larger.
• Always tip up the machine after grinding when removing glue or when wet grinding so that
the machine does not stick to the floor and damage machine parts upon restart.
• The control current must always be cut and the mains connection disconnected when repla-
cing grinding discs.
• The grinding discs may be hot following grinding. Let the machine stand in tipped position
for a few minutes and wear gloves when you remove the grinding discs.
• Cut the current to the machine when repairing.
