Battery returns and/or adjustments are made through battery distributors.
POWER TRAIN
See Lubrication Specifications Section. Check hydraulic oil level daily using the sight
gauge located on the hydraulic tank. A 1/2- 3/4" air bubble will be seen at the top of the
gauge. Keep filled to proper level with Mobil 424 Hydraulic oil or equivalent. Your local oil
vendor can determine compatible oils. Mobil 424 Hydraulic Oil or equivalent should be
changed every 200 hours. The Hydraulic Oil Filter needs to be changed every time the
Hydraulic Oil is changed. For temperatures below 35 degrees, oil should be switched to
thinner 15 weight hydraulic fluid.
For satisfactory operation, the following oil conditions apply:
•
Accurate level readings can be obtained only when the fluid is cold and machine is
on level ground.
•
If the natural color of the fluid has become black or milky, it is possible that an
overheating or water contaminant problem exists.
•
DO NOT mix hydraulic fluids. See Lubrications Specifications Section for hydraulic
system recommendations.
•
Add hydraulic oil through breather tube. Pour hydraulic oil through strainer
basket into hydraulic tank.
The hydraulic drive motors are extremely reliable and will ordinarily not need maintenance
or repair. If a vibration is experienced with engine running, check the coupler between the
engine and the hydraulic pump. Do not make this inspection while engine is running. It will
be necessary to remove the inspection cover. After adjusting and tightening the coupler,
replace the inspection cover and then start engine to see if the problem has been corrected.
Do not run the engine or operate the buggy with the cover removed or not firmly attached.
