Checking Hydraulic Oil
Check the oil level of hydraulic units only when the
engine is OFF.
During initial break-in (first five hours of operation),
check oil before each use and after every hour of
operation.
During normal operation, check oil after 50 hours of
operation.
• Flip seat up and clean the area around the
hydraulic oil dipstick to prevent debris from entering
the crankcase. See Figure 15.
• Remove the hydraulic fill plug/dipstick and read the
level:
If hydraulic oil level is inside operating range, then do
nothing.
If hydraulic oil level is below operating range, the add
hydraulic oil before operating. Also check for leaks.
If hydraulic oil level is above operating range, then drain
excess oil before operating.
• Reinstall the dipstick completely into the fill tube.

Adding Hydraulic Oil
WARNING: Never overfill the hydraulic
units. Damage can result if the oil level is
not within the operating range. When
adding hydraulic oil, do so in small
quantities and recheck the oil level before
adding more.
