MAINTENANCE WORK AND REPLACEMENT OF WEARING PARTS
Certain maintenance jobs ought to be performed from time to time,
at the latest, however, when damage is established or the red LED
of the pressure control sensor lights up. Use only LÄGLER original
spare parts. Perform the job in a clean, brightly lit working environ-
ment and follow the directions given in this manual. In the tool bag
you will find all the tools needed for the jobs described below.
6.1 CLEANING AND CARE
Never use solvent-based cleaning agents.
Before starting work you should carry out the following care and
maintenance steps to guarantee proper machine function and a
first-class sanding result:
• Clean the running wheels on the machine.
• Carry out a visual inspection of the electrical equipment (extension
cable, plug, couplings).
• Check the sanding discs, rubber jigs and fl exible bases of the sanding
discs for damage.
6.2 CLEANING THE FILTER
In general the machine’s filter should be cleaned after each dust
bag change; at the latest this should be done when the red LED of
the pressure control sensor lights up. If this happens while you are
in the middle of a sanding job you may as well finish a half-trodden
path first.
If you do not clean the filter in spite of the red light indicating that
this is necessary, the suction performance will become less and
less efficient with time, and the dust emission will increase. This,
of course, will mean a higher health risk for the machine operator.
Furthermore, the cleaning of filter cartridge and dust separator will
prove troublesome and time-consuming.

ATTENTION!
Comprehensive maintenance work, particu-
larly work on the electrical equipment, must
be done by an expert for safety reasons!
Maintenance work on the electrical equip-
ment, motor or pressure control sensor may
only be carried out when the machine is
switched off and the mains plug discon-
nected from the wall socket. Otherwise
mortal danger!
Never blow compressed air into the dust
bag box or the neck of the suction hose on
the dust separator as otherwise the highly
sensitive pressure control sensor could be
damaged.
