Hydraulic Fluid and Filter Change
The hydraulic fluid should be changed
every 500 hours, and the hydraulic filter
should be changed every 250 hours.
Hydrostatic components require
extremely clean oil in order to have a
long service life. Extreme caution must
be taken when changing the hydraulic
fluid. Before beginning the procedure,
make sure the machine is in a clean
working environment. Precautions
should be taken to prevent any debris
from entering the hydrostatic system.
1. Remove the middle skid-plate from
the bottom of the machine. Locate
and remove the hydraulic fluid drain
plug (photo D), and drain into suit-
able container.
2. Locate the hydraulic filter behind the
operator’s compartment, under the
left rubber plug (photo E, item 1).
3. Clean around the filters and remove.
4. Replace the filter with ASV approved
filter.
5. Replace the drain plug and skid-plate
and fill the hydraulic reservoir (photo
E, item 2) with ASV Posi-Lube
Premium All Season MV Hydraulic
Oil, or approved hydraulic fluid such
as Chevron Rykon MV. The hydraulic
fluid level sight gauge is located on
the back of the hydraulic reservoir
(photo F).
