HYDRAULIC OIL FILTER (SUCTION & HST)
The hydraulic system is equipped with spin-on
type oil filters.
NOTE: Replace the filters after the first 50
hours of operation and every 300 hours
thereafter following the procedure below:
1. Remove the drain plug A of the front gear
case and discharge the HST oil.
2. Unscrew the oil filter B, C and discard.
3. Coat the gasket on the new filter with a film of
oil. Screw the filter into place until the gasket
contacts the sealing surface, then tighten the
filter approximately 3/4 of a turn by hand. Do
not over tighten.
4. Install the oil filter in place and supply new
HST oil from the oil inlet D.
5. Start the engine and check the hydraulic oil
filter for leaks.
6. Stop the engine and check the hydraulic oil
level. Replenish if necessary.
