Change Hydraulic Oil and Filter
Change hydraulic filter initially after the first 5 0 operating
hours, thereafter change hydraulic oil and filter after ev-
ery 800 hours. Contaminated oil looks milky or black
when compared to clean oil. If oil becomes contami-
nated, flush hydraulic system (see Flush Hydraulic Sys-
tem).
Note: If oil is not going to be drained, disconnect and
plug hydraulic line going to filter.
1. Clean area around filter mounting area. Place drain
pan under filter and remove filter. Allow hydraulic oil to
drain completely.
2. Fill replacement filter with hydraulic fluid (see Check
Hydraulic System Fluid), lubricate the sealing gasket
and hand turn until gasket contacts filter head. Then
tighten 3/4 turn further. Filter should now be sealed.
3. Fill hydraulic reservoir with approximately 5.5 gal-
lons (8.1 gallons if machine is equipped with leak detec-
tor) of hydraulic oil (see Check Hydraulic System Fluid).
4. Start engine and run it at idle for 3 to 5 minutes to
circulate the fluid and remove any air trapped in the sys-
tem. Stop engine and recheck fluid level.
5. Dispose of hydraulic fluid properly.
