2. Adding Oil
To add oil, remove the oil filler cap located at the top of the
oil reservoir (Fig. 4.7B). Check and ensure the filter screen
in the filler neck is undamaged. Add 10W30 API
Classification SJ oil until oil is visible in the oil level sight
glass (Fig. 4.7A).
3. Hydraulic Filter Replacement
The hydraulic oil filter (Fig. 4.7C) must be changed after
the first 50 hours of operation and every 150 hours
thereafter.
To change the filter; shut off the engine, lower the lift
arms, ground any attachment and set the parking brake.
Open the rear door and using an oil filter wrench remove
the filter element. Lubricate the new filter seal with system
fluid and reinstall hand tight. Note: The loader has one
filter.
4. Draining System Fluid
Change the hydraulic oil:
1. After 1000 operating hours.
2. If the oil has become contaminated.
3. After any major hydrostatic repair.
To drain the oil: remove the drain plug located at the
bottom of the reservoir (Fig. 4.7D). Have sufficient
containers ready to hold the fluid. Remove any metal
particles stuck to the magnet. Seal the plug with teflon
tape when replacing.
