Proper Oil Level
Maintain the oil level within the sight gauge located
on the reservoir. When oil is cold, the level should
be three-quarters up the sight gauge. Never fill the
tank above that sight gauge level. A space is
maintained above the sight gauge to allow for the
expansion of the oil. Oil is added through the filler
tube, if your tank does not have a filler tube then fill
through the return filter located on the tank.
Thoroughly clean the cap area around the filter to
prevent oil from contamination. Remove the cap
and add the proper viscosity grade of FILTERED oil
to achieve the proper level. Never assume any oil is
clean, including new.
Oil Level Low
Low oil level in the reservoir is caused by leakage or improper filling. If leaking, locate the area of the leak and
repair the leak at once. Loss of fluid can cause severe & catastrophic damage to the hydraulic components.
NOTE: After initial start up, the mower may require more oil to bring the oil level back to the proper level. This
is normal. Air trapped in the hydraulic components was displaced by the oil, causing the oil level to go down in
the tank. Oil must be added to reach the proper level or cavitation could result.
