4. Safety instructions
4.1 General safety instructions
- Follow all safety rules, regulations and conditions when using the glass polisher.
- Disconnect the mains plug before carrying out any maintenance work.
- Always keep the glass polisher in good condition. Check that all moving parts can move freely.
- Always have damaged components replaced by a competent person and always use original parts.
- Always keep the glass polisher clean.
- Keep your work area clean and free of unused materials. Ensure that there is sufficient lighting.
- Avoid unintentional switching on of the glass polisher.
- Always wear approved closed-sided safety glasses, ear protection and gloves when using the glass polisher.
- Dry grinding of glass produces fine dusts. Wear a suitable dust mask.
- Avoid wearing loose clothing or jewellery and tie up long hair.
- Make sure the floor is not slippery and wear non-slip shoes.
- Keep children and unauthorised persons away from the work area.
- Do not operate the glass polisher if any parts are missing or defective. This can lead to failure and injury.
- Do not use the glass polisher until you have been instructed by a qualified person or have read the operating instruc-
tions.
- Do not operate the glass polisher in rooms where flammable gases, liquids or solids are present.
- Never leave the glass polisher unattended.
- Do not operate the glass polisher when you are tired or under the influence of alcohol, drugs or medication.
- Do not use the glass polisher in a damp environment.
- Store the glass polisher in a safe, dry place out of reach of children at a temperature not exceeding 40°C (104°F).
- The plug on the glass polisher must fit into the socket. Never modify a plug. Do not attach an adapter plug to the e-
arthed glass polisher. Original plugs and matching sockets reduce the risk of electric shock.
- Use the cable as directed. Never use the cable to carry, pull or disconnect the glass polisher from the power supply.
Keep the cable away from heat, oil, sharp edges or moving parts. Damaged or tangled cables increase the risk of
electric shock.
- When working outdoors, connect an extension cord approved for outdoor use. Using a cable suitable for outdoor use
reduces the risk of electric shock.
- If operation of the glass polisher in a damp place cannot be avoided, use a residual current circuit breaker. The use of a
residual current circuit breaker reduces the risk of electric shock.

Operating Instructions Glass Polisher BO 5009337- Version 1.0 4
- Remove all adjusting keys or spanners before switching on. Spanners stuck on rotating tool parts can cause injury.
- Do not lean over the tool. Always maintain a firm grip and balance. This makes it easier to control the power tool in un-
expected situations.
- Lay the power line at a sufficient distance from rotating parts. If you lose control of the glass polisher, the line may be
cut or strained and your hand or even arm may get caught in rotating parts.
- Never put the glass polisher down until all rotating parts have come to a complete standstill. Rotating parts can rub
against the supporting surface and make the power tool uncontrollable
- Do not leave the glass polisher in operation while you are carrying it by your side. In case of accidental contact, rotating
parts can get caught in your clothes and cause injury.

Wet the polishing medium evenly and completely with the polishing liquid before starting the machine.
Start the machine with the polishing medium on and begin the polishing process with high pressure.
Reduce the pressure in the last 2 -3 seconds of polishing and stop the process as soon as the imperfections are polished out. Do not allow the polishing
liquid to dry on.
Remove the residue with a soft and dry cloth.
