LUBRICATION
6.2 LUBRICATION
For general upkeep of the machine, after around 100 operating hours
we recommend sparing lubrication of the two lubrication nipples
at the wheel bearings using a manual grease gun (tool kit) using
ball bearing grease.
In order to guarantee lasting easy running of the moving parts,
lubricate at regular intervals at the following lubrication points
(Fig. 31).
A Top part of the rod linkage at the lever plate
B Lever plate on the handle shaft
To do this, tilt the machine slightly to one side and allow a small
amount of oil to run into the lubrication points.
C Wing screw on the bottom part of the rod linkage
D Guide tube in the machine housing
E Wing nut at the housing
Use customary lubricating oil for these lubrication points - never
use grease or sprays such as WD 40 or similar!
6.3 CHECKING SANDING BELT REGULATION
The sanding belt tracking must be checked every time the sanding
belt is exchanged, but at least once a day.
Should readjustment be necessary, proceed as follows:
1 Switch the machine off and pull the mains plug out of the
socket!
2 Remove the side cover (Fig. 32).
3 Check whether any soiling at the tensioning roller calls for
readjustment. If so, the tensioning roller must be cleaned
(Section 6.1.1) and the belt tracking must be checked again
(Section 4.2.8).
Fig. 32 Release the cover lock and remove the side
cover.

IMPORTANT
In newer models, this lubrication point has been replaced by a self-
lubricating plastic bushing. This bushing does not require lubrication!
Never use sprays such as WD 40 or similar!
