every 50 hours. Check more often if operating in
dusty or grassy conditions. Clean as needed.
To clean:
• Clean fins with compressed air or spray wash.
• Open rear hood and spray through radiator
toward engine.
• If grease and oil are present on radiator, spray
with solvent and allow to soak overnight.
Change Hydraulic Filters (Initial
Service)
Change hydraulic filter after first 50 hours. Replace
filter every 500 hours thereafter. Change filter more
often if indicated by filter indicator.
Check Ground Drive Gearbox Oil Level
Check oil level in both ground drive gearboxes
every 50 hours. Rotate plug (shown) until level with
center of gearbox. Open plug. If oil does not come
out, add MPL as needed. Never fill more than
halfway.
IMPORTANT: Be careful not to damage fins
with high pressure air or water.

opened for repair, install new filter (p/n 153-791)
