HYDRAULIC SYSTEM
WARNING Hydraulic reservoir is under pressure. Avoid contact with leaking hydraulic fluid or diesel fuel under pressure. It can penetrate the skin or eyes and cause severe injury. Checking Hydraulic Oil Level 1.
Position the machine on a level surface.
2.
Fully extend the bucket and boom. Lower bucket and dozer blade to the ground (Figure 4-12). Turn off the machine.
3.
Pull the valve cover latch lever (Figure 4-1) and open the valve cover to expose the hydraulic oil level indicator (Figure 4-12).
4.
Check the hydraulic oil level indicator (Figure 4-12). Oil level should be between black and red marks on sight glass. If hydraulic oil is required, proceed to step 5.
5.
Remove access panel located on top of valve cover (Figure 4-13) to expose the hydraulic oil cap.
6.
Slowly open the cap to relieve pressure.
7.
Add hydraulic oil until oil level is between red and black marks on indicator (Figure 4-12).
8.
Re-install hydraulic tank cap and tighten securely.
9.
Start engine and let idle for a few minutes to build up pressure.
