Regular Maintenance

 1.  Lift up the seat plate to gain access to the oil 

reservoir compartment.

 2.  Look at the hydraulic oil reservoir (A, Figure 13) 

and observe the oil level.  When cold, the oil level 
should be approximately 1/2” (1,3cm) below the 
MAX. HOT OIL LEVEL line.  The oil level should 
never be above the MAX. HOT OIL LEVEL line.

 3.  If necessary, remove the reservoir cap (B, Figure 

13) and add either Mobil 1, 15W-50 synthetic 
oil or Castrol Syntec 5W-50 oil.  DO NOT use 
conventional oils.  Make sure area around the fill 
neck of the reservoir is free of dust, dirt, or other 
debris. 

Change Interval:  Every 500 Hours

Filter Part Number:  5021357

 1.  Locate the hydraulic oil filter (A, Figure 14) behind 

the oil reservoir.

 2.  Fill the new filter with oil.  Lubricate the new filter 

seal with a few drops of oil.

 3.  Remove the oil filter and quickly thread the new 

filter onto the filter base until the gasket makes 
contact, then tighten 3/4 of a turn more.

 4.  Refill reservoir with fresh oil to replace any oil lost 

during filter change.

 5.  Raise the rear of the unit and secure with 

jackstands.  Chock the front wheels to prevent the 
unit from rolling.  Run the unit for several minutes 
to purge any air from the hydraulic system and 
check the hydraulic oil level.

Inspect the muffler for cracks, corrosion, or other 
damage.  Remove the spark arrester, if equipped, 
and inspect for damage or carbon blockage.  If 
replacement parts are required, make sure to use only 
original equipment replacement parts.
