Check Hydraulic Fluid Level
1. Remove the breather filler cap (246).
2. If the fluid level is between the high and low tick
marks, the fluid level is correct.
3. If the fluid level falls below the low fluid level tick
mark, add fluid until the level is between the high
and low level tick marks.
Check Condition of Hydraulic Fluid

on page 21.
3. Place a container below drain port.
4. Remove drain cap (87) from the side of the hydraulic
reservoir and drain the reservoir.
5. Install drain cap (87).
6. To add clean hydraulic fluid see Check Hydraulic

Replace Hydraulic Filter
1. Shutdown the system. See Shutdown on page 21.
2. Relieve Pressure. See Pressure Relief Procedure
on page 21.
3. Use compressed air to remove any loose debris
around the hydraulic filter (245).
4. Apply a light coat of hydraulic fluid to the sealing
surface of the new hydraulic filter (245).
5. Replace the old filter with the new filter (245).
