MAINTENANCE
HYDRAULIC SYSTEM
Fluid level in the hydraulic system should be
checked after the first 5 hours of operation, and
every 100 hours thereafter, or when a leak has
occurred. If the fluid is low, check all components for
leaks.
To check, remove reservoir cap M. The fluid level
should be at the bottom of the filler tube. If low, top
up (do not overfill). Use one of the oils listed below:
– SAE 15W40 motor oil
– SAE 20W50 motor oil
– 15W50 synthetic motor oil
AFTER FIRST FIVE (5) HOURS
1. Remove discharge deflector F, (4) U-bolts with
(8) nuts H.
2. Remove plug N to drain hydraulic reservoir.
Dispose of used oil in accordance with local
requirements.
3. Clean and replace the plug.
4. Change hydraulic oil filter G.
5. Fill the reservoir with fresh oil to the bottom of
the reservoir filler tube, using an oil from the list
above. Do not overfill.
6. Replace discharge deflector F, (4) U-bolts with
(8) nuts H.
PERIODIC OIL CHANGES
Change the hydraulic fluid and hydraulic filter after
each 500 hours of operation using the same
procedure given above.
NOTES:
Before servicing the hydraulic system, stop the engine, disconnect spark plug wires and disengage the
PTO.
– After any hydraulic line is opened, plug or cap it promptly to reduce the risk of contamination.
– Do not use teflon tape on hydraulic pipe fittings. Use a liquid sealant that will dissolve into the system.
– Make sure all hydraulic connections are tight and hydraulic hoses and lines are in good condition
before applying pressure to system.
The machine's hydraulic system operates under high pressure. When checking for leaks, do not use your
hands to attempt to find a leak. Instead, use cardboard or paper. Escaping hydraulic fluid can be under
sufficient pressure to penetrate skin and cause serious injury. If hydraulic fluid is injected into the skin, it
must be promptly removed by a doctor familiar with this form of injury or gangrene may result.
