TROUBLESHOOTING

Loss of Power:

1. Make sure the power cord is properly fastened to the motor head, and it is properly
plugged into the socket.
2. Be sure the electrical circuit has not blown a fuse.
3. If the circuit is functioning properly, but there is still no power, contact Nilfisk-
Advance America's Customer Service Department at (800) 645-3475, extension 2.

Loss of Suction:

If the GM 80 loses suction power during operation, there may be several reasons,
the most likely of which is a full container. Suction loss is gradual as the container fills
with debris. Check to see if there is any blockage or restriction in hose. Next, check the
condition of the main filter and microfilter (refer to photos) and determine whether there
is an excessive loading of debris. If there is overloading in the main filter, you can shake
it. If the microfilter is loaded, it needs to be replaced. Call our Customer Service
Department at (800) 645-3475, extension 2 to order replacement filters.
If all fails, call our Customer Service Department.
3. ULPA Exhaust Filter: The ULPA (Ultra Low Penetration Air)
filter ensures that 99.999 percent of all ultrafine particles,
toxic and nuisance, are retained – down to and including 0.12
microns. The ULPA filter cartridge is mounted on the top of
the motor, outside the container (photo 7). If the main filter
and microfilter are properly maintained, the glass fiber
element in the exhaust filter should perform satisfactorily for a
minimum of one year. It cannot be renewed or restored. Exact
life will depend upon frequency of use and amount and type
of material collected. Normally four changes of microfilter
equal one change of the ULPA filter. Remove the protective
metal casing and replace the pleated glass fiber cartridge
according to the accompanying instructions. Cartridges must
be replaced more frequently if the cleaner has had unusually
heavy use, or if the various pre-filters have been neglected.
