switching on of the machine!
Therefore: Switch the machine off and disconnect it from the power
supply be-fore any maintenance works or cleaning is carried out
The machine does not require extensive maintenance. If malfunctions and defects occur, let it be
serviced by trained persons only.
Before first operation as well as later on every 100 operation hours you should lubricate all con-
necting parts (if required, remove beforehand with a brush all swarfs and dust).
Check regularly the condition of the security stickers. Replace them if required.
Check regularly the condition of the saw band and the saw band guide.
The good condition and perfect adjustment of the guiding rollers is essential for a smooth band
guidance and a clean cut.
Store the machine in a closed, dry location.
NOTICE
Clean your machine regularly after every usage – it prolongs the machines lifespan and is a
pre-requisite for a safe working environment.

15.1 Maintenance plan
After each workshift: Remove chips and sanding dust from the device
After 10 hours of operation: Check all screw connections and tighten if necessary.
15.2 Changing Sanding Belt
1. Remove the plastic Side Cover (#60) from the
frame by unscrewing the knob (#78).
2. Remove the Small Fence (#56).
3. Slide Tension Lever (#71) to the right to release
the belt tension.
NOTE: Above the Tension Lever, there is a direction
arrow. The sanding belt must run in the direction of
this arrow so that the splice does not come apart.
4. Remove the old belt by sliding it off to the left of
the frame. Place the new sanding belt over the
drums with the direction arrow pointing in the
proper direction. Make sure the belt is centered on
both drums.
5. Slide the tension lever to the left to apply tension
to the belt.
6. Re-install the small fence and side cover onto the
frame (removed in Step 1 & 2).
7. Plug in the power cord. Turn the switch “ON” and
note if the belt tends to move to the right or left on
the drums. The belt should be running on the center
of the drive drums. If it is not, the belt tracking
needs adjustment.
