Engine air filters [51273268]
The air filter should be checked 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 non-authorized 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.
NOTE: Replace the primary element if the filter warning lamp on the instrument cluster illuminates or the audible alarm
sounds. Should the caution warnings continue after replacing the primary filter, replace the secondary filter as well
