FIGURE 4 

When initially putting hydraulic system into 
service, one or both of the wheel drives may not 
pull properly. This is likely to be caused by air 
entrapped in the system. If you experience a 
pulling issue during initial setup or after completing 
repairs, perform the following procedure to purge 
the air from one or both of the hydraulic drive 
systems. 

FLUID FILTERS, PRE-FILL BOTH WITH OIL 
(SAE 20W50 API SL) BEFORE INSTALLING. 
PRE-FILLING THE FILTERS WITH OIL WILL 
REDUCE OR POSSIBLY ELIMINATE THE NEED 
TO PURGE THE SYSTEM OF ENTRAPPED AIR. 
A. Locate hydraulic reservoirs underneath 
operator’s seat. After thoroughly cleaning the area 
around the top of each reservoir, remove filler cap. 
Bring fluid to proper level (1-1/2” below the top of 
the filler neck).  With engine off, add SAE 20W50 
automotive oil. See Figure 5. 
B. Open pressure relief valve on hydraulic pump, 
turning counter clockwise 2 full turns. See Figure 
6. 
C. Carefully raise the rear of the machine so the 
wheels are off of the ground. Securely block the 
machine to prevent it from falling. 
D. While seated in the operator’s position, start the 
engine. Place engine speed control in FAST 
position. 
E.  Release parking brake and move motion 
control levers out of the neutral lock position. 
F.  Slowly move motion control levers to the full 
forward and then to the full reverse positions. 
Repeat this process 6 times. 
G. Stop engine and wait for all rotation to stop 
before leaving the operator’s position. 
H. Close pressure relief valve on hydraulic pump, 
turning clockwise. Tighten snuggly. 
I.  With pressure relief valve closed, repeat Steps 
D thru G. 
J. Remove blocks and lower rear of machine.  

K. Check fluid level in reservoirs. Add SAE 20W50 
automotive oil as required to bring fluid level to 1-
1/2” from top of filler neck. Do Not overfill. 
L. Install and tighten filler cap.
