5.1. General
We recommend regular inspection of all seals.
Warning!
When changing tools or making repairs, the power to the machine
must be disconnected.
Warning!
Use safety equipment such as shoes with steel toecaps, goggles,
protective gloves, a mask and hearing protection.
5.2. Cleaning
Warning!
Do not clean the machine with a high-pressure washer, otherwise
moisture may penetrate electrical elements and damage the
machine’s drive system.
• Always clean the machine after use with a damp sponge or
cloth.
5.3. Daily
• Wash the machine if it is used for wet grinding.
• Check for grinding tool wear – abnormal or uneven wear
may indicate a damaged grinding holder.
• Check the tool holder and grinding holder to ensure that no
damage or cracks have arisen. Replace the parts if there is
any damage.
5.4. Every week
• Wash the machine.
• Check the grinding holders. Remove the tools and run
the machine in the air at the lowest speed. If the grinding
holders oscillate or wobble significantly, they are damaged.
