MAINTENANCE
Cleaning the Main Filter
NOTE: It is advisable to replace the filter when it is dirty. However,
in an emergency it is permissible to clean the main filter if you ob-
serve the following practices.
1. Never immerse the filter in water since dirt can be transferred
to the clean air side of the filter.
2. If compressed air is used never exceed a pressure of 40 PSI.
Always use a dispersion type nozzle to prevent filter damage
and clean from the inside to the outside.
NOTE: Replace the air filter every 50 hours, and possibly more
often in very dirty conditions.
