5. Maintenance
At the end of every day of working with the belt
sander, the following maintenance measures
should be taken:
• Clean the machine of dirt and sanding dust
after every use to prolong its operating lifetime.
This will also prevent the machine from being a
fire hazard after you are finished with your work.
• Check the V-belt tension and loosen any parts
of the machine that are under tension.
• Inspect the power cables for damage and
check the electrical contacts.
• Remove the dust bag and empty it as recom -
mended.
• Check that the screws are tight, and give the
sanding belt some slack or remove it from the
machine entirely.
In addition to the recommended daily mainte-
nance measures, the following tasks should be
completed after approx. every 400 hours of use
(PM 1):
• Clean the dust suction and capture system.
Check that the fuses are intact and the cable con-
nections to the control unit are firm and undam -
aged. If you discover any defects in the electrical
systems of the machine, have them repaired by a
trained professional.
• Tighten all screw joints and lubricate all moving
parts of the belt sanding machine. Do not forget
to lubricate the bearings as well.
Further periodic maintenance tasks should be
completed after approx. every 1,400 hours of
use (PM 2): In addition to completing the steps
of PM 1, clean the ventilation system and the
drums.
4. Storage
When storing the machine for extended periods
of time or transporting it over long distances,
protect any uncovered surfaces from corrosion
using a rust-protective oil compound. Loosen
the V-belt when storing the machine for an
extended period of time. The machine must not
be exposed to wet or damp storage conditions.
Therefore, always store it in dry rooms. Also,
always make sure to store the machine out of the
reach of children.
