2. Hydro Pumps
Check the level of the fluid in the fluid reservoir. Wipe
away all dirt and debris from around reservoir cap
before removing. Oil must remain absolutely clean!
Check with machine on a level surface with engine
"OFF". Fill reservoir as needed to bring level up. The
reservoir is properly filled when the fluid level is 1½"
below the top of the filler neck. DO NOT OVER FILL.
Use clean, fresh premium automotive oil having a vis-
cosity equivalent to SAE 20W50 API SL. The fluid
should be chemically stable, incorporating rust and
oxidation inhibitors. Make sure funnels, pouring spouts
and oil can are completely clean. Reinstall reservoir
cap. See Figure 4.6.
3. Other Lubrication Points
Lubricate machine caster wheel shafts and traction
idler arm with Kendall NLGI No. 2 lithium grease or
equivalent, from a grease gun. See Figure 4.7.
