7 - MAINTENANCE
Engine air filters
Check the engine air filter periodically for dirt and debris build up. Replace the engine primary and secondary air filter
every 2000 hours or each year, whichever occurs first.
Prior operation:
Keep all unauthorized personnel clear of the area. Park the machine on level ground, in neutral with the parking
brake applied, and the attachment lowered to the ground. Make sure that all residual pressure is relieved from circuits
before beginning maintenance.
NOTICE: Replace the primary element if the filter warning lamp on the instrument cluster illuminates or the audible
alarm sounds. If the caution warnings continue after replacing the primary filter, replace the secondary filter. Under
normal conditions, you should replace the secondary filter after three primary filter replacements. Replace filters more
often if conditions so warrant. DO NOT clean the secondary filter. You must replace the secondary filter.
