CLEANING
Pressure wash machine. Inspect machine for any damage or missing parts. Drive machine to check
steering linkage for damage.
HYDRAULIC SYSTEM
Start engine and allow it to idle for a few minutes. Drive machine around for 2 – 3 minutes. Raise and lower
boom 2 – 3 times. Crowd and dump bucket 2 – 3 times. This will circulate hydraulic fluid through all
hydraulic systems.
LUBRICATION
Perform all daily maintenance procedures listed in this section (Section 4.) Grease all grease fittings in
steering linkage. Apply a coating of light oil to all exposed cylinder rods. Apply a coating of light oil to all
control linkages and all control valve spools. Check condition of oil coating each month and add to coating
where necessary.
BATTERY
Disconnect cables from battery, or remove battery from machine. If battery is removed, fully charge battery
and store it.
COOLING SYSTEM CARE
If cooling system does not need antifreeze and is filled with water only, add an anti-rust additive. If
temperatures below freezing are expected, add antifreeze to protect system to level of cold expected. See
antifreeze protection Table 4-1. Use a hydrometer to check level of antifreeze protection once each month.
If desired, cooling system can be completely drained. If system is drained, place a sign in operator's cab to
warn operator that there is no coolant in engine.
