Inspect Bolts on Rams
Each day, visually inspect the bolts on the rubber rams.
If you see something unusual, shut o󰀨 the engine, put
the key in your pocket and remove the waterbox cov-
ers and inspect with a wrench. If you nd that they are
loose, tighten with a torque wrench to the “Torque Spec-
ications for Metric Bolts” listed in the Appendix section.
Remember to replace the waterbox covers before using
the machine.
Grease the Rock Valve and Agitator Bearings
Grease the Rock Valve and agitator bearings using the
manual greasing station located on the rear, passenger
side of the stationary pump (Figure 6). If your unit was
equipped with the optional automatic greasing system,
check the grease levels each day and check for any
damage or leaks in the system.
