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.
To change the oil and filter:
1. Remove the middle skid-plate from
the bottom of the machine. Locate
and remove the hydraulic fluid drain
plug (item 3), and drain into suitable
container.
2. Locate the hydraulic filter behind the
operator’s compartment, under the
left rubber plug (item 4).
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 (item 5)
with
ASV 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 (item 6).
