5. Maintenance
For safety reasons, the mains plug must always be disconnected
before undertaking any maintenance work on the machine unless
indicated otherwise.
5.1 Sharpening the grinding wheel
☞
Sharpen the wheel regularly!
When? If the grinding noise increases, the ground surface shinier and the
workpiece hotter than when the grinding wheel is sharp, the later
should be sharpened.
Procedure • Clamp the sharpening device (with corundum block protruding at
least 3 mm) onto the rotary tool holder
• Slide the locating stop to the left; a certain amount of resistance
must be overcome when doing so, and lower it carefully onto the
top of the corundum block
☞ Caution: The corundum block may fracture!
• Then slide the stop to the right
• Loosen attachment of corundum block - pull it out upward 10-15
mm - clamp corundum block
• Close flap. The machine cannot be started with the flap open
• Main switch ON
• First pull, then press the feed button
• Pull the feed button once the visibly rapid descent of the top stops;
this improves sharpening results!
• To switch off: Main switch OFF
