9.6 Replace the Hydraulic Fluid and
Filter
WARNING!
Read and understand the Hydraulic System
Safety on page 38.
CAUTION!
Risk of burns to exposed skin.
Hydraulic fluid gets hot during
operation, which makes hoses,
lines, and other parts hot as well.
Wait for the fluid and components to
cool before starting maintenance or
service.
Change the hydraulic fluid and filter every 100 hours of
operation or annually.
For hydruaulic fluid information, see Hydraulic Fluid on page
59. The hydraulic reservoir capacity is 4.6 US gal (17.5 L).
Wait until the machine temperature decreases before changing
the hydraulic fluid. However, it is best to change the hydraulic
fluid while the machine is warm to keep any contaminants in
suspension.
The drain plug is on the bottom of the hydraulic reservoir. The
filter is beside the hydraulic reservoir (below the main boom
rotate).
1. Set the machine to a safe condition.
For instructions, see Safe Condition on page 9.
2. Place a drain pan under the drain plug and filter. Make sure
that the drain pan is large enough to collect and contain the
hydraulic fluid that will drain from the filter and reservoir.
3. Clean the area around the drain, and then remove the drain
plug.
4. Clean around the filter connection, and then turn the filter
counterclockwise to remove it. A filter wrench may be
necessary.
5. Wait for the hydraulic fluid to fully drain from the reservoir
and filter connection.
6. On a new filter, apply a light coat of clean hydraulic fluid to
the seal.
7. Turn the new filter clockwise to install it. Tighten the filter by
hand, and then turn it one more 1/4 turn.
8. Install the drain plug.
9. Fill the reservoir to the top mark on the dipstick.
For more information, see Add Hydraulic Fluid to the
Reservoir on page 39.
10. Start the machine.
For instructions, see Start the Machine on page 41.
11. Operate the hydraulic controls for one to two minutes to
remove air from the hydraulic system.
12. Examine the filter connection for leaks.
If necessary, turn the filter one more 1/4 turn.
13. Stop the machine.
For instructions, see Stop the Machine on page 41.
14. Check the hydraulic fluid level. Add fluid, as necessary.
For instructions, see Check the Hydraulic Fluid Level on
page 38.
15. Dispose of the used hydraulic fluid in an environmentally
safe manner.
