How to Perform Planned Maintenance
ENGINE OIL PERFORMANCE DESIGNATION
: Refer to the “Engine Oil” in Section 8.
Hydraulic Sump Tank
Check the hydraulic sump tank fluid level. Correct fluid level is
important for proper system operation. Low fluid level can cause
pump damage. Overfilling can cause loss of fluid or lift system
malfunction.
Hydraulic fluid expands as its temperature rises. Therefore, it is
preferable to check the fluid level at operating temperature (after
approximately 30 minutes of truck operation). To check the fluid
level, first park the truck on a level surface and apply the parking
brake. Put the upright in a vertical position and lower the fork
carriage fully down. Pull the dipstick out, (attached to the sump
breather) wipe it with a clean wiper, and reinsert it. Remove dipstick
and check oil level. Keep the oil level above the LOW mark on the
dipstick by adding recommended hydraulic fluid only, as required.
Do
not overfill
.
Check the condition of the hydraulic fluid (age, color or clarity,
contamination). Change (replace) the oil as necessary.
Hydraulic Fluid and Filter Change
Drain and replace the hydraulic sump fluid every 2000 operating
hours. (Severe service or adverse conditions may require more
frequent fluid change). Replace the hydraulic oil filter elements at
every oil change. Remove, clean, and reinstall the hydraulic and
steer system suction line screens at first PM and every 1000 hours
thereafter. Check for leaks after installation of the filters. Also, check
that the hydraulic line connections at the filter adapter are tightened
correctly. The procedure for draining hydraulic sump tank is in your
Service Manual.
