MAINTENANCE
Hydraulic Fluid
Maintaining the proper level and cleanliness of the oil is very important for the continued trouble-free operation
of the mower and should be checked each morning before the mower is started. Check for any leaks and
tighten any fittings which may be loose. The factory hydraulic oil fill is Mobil DTE 16m or an ISO AW68
equivalent. This oil is adequate for most summer mowing conditions throughout the country.
Note: Your ambient temperature and operating conditions may require a different viscosity oil. Please consult
the oil manufacturer for proper specifications.
Proper Oil Level
Maintain the oil level within the sight gauge
located on the front of the reservoir. When oil is
cold, the level should be halfway on the sight
gauge. Never fill the tank above the sight gauge
level. A space is maintained above this sight
gauge to allow for the expansion of the oil. Oil is
added through the Filler Breather Cap located in
the top of the tank. Thoroughly clean the cap area
around the filter to prevent oil contamination.
Remove the cap and add oil. Use the oil
appropriate for the operating temperature range
as shown in decal P/N 02982828. Only add
FILTERED oil to the tank using either prefiltered oil
or by using a filter cart. Never assume any oil is
clean, not even from a new container.
Oil Level Low
Low oil level in the reservoir is caused by leakage of oil. Locate the area of the leak and repair the leak at
once. Loss of fluid can cause severe damage to the hydraulic pump and motors.
NOTE: After the first day of operation the mower may require more oil to bring the oil level back into the sight
gauge. This is normal. Air trapped in the lines and tanks was displaced by the oil, causing the oil level to go
down.
Filter Change - After the first 25 hours of operation, change the oil filters. Replace the oil filters with the new
ones provided for you. Thereafter, replace these filters every 500 hours or when the filter condition gauge
shows they need to be changed.
