1. Level the crane, engage the parking brake and shut off
the engine.
2. Look through the grate behind the engine, coolant
should be visible in the sight gauge (Figure 5-22).
3. If level is low, add only a 50-50 mixture of glycol
antifreeze and water, do not add only water as this could
cause rust to form in the radiator and engine.
NOTE: For more details on proper radiator checking and
maintenance procedures, See the engine manual
furnished with the crane.
Drain Water from Engine Fuel Filter/ Water Separator
1. Shut off the engine and engage the parking brake.
2. See the engine manual furnished with the crane and
follow the water draining instructions.
Check Hydraulic Oil Level
If the hydraulic oil is constantly low, check for leaks in the
hydraulic system.
1. Be sure the boom is fully retracted and lowered and the
outriggers are retracted and up.
2. Level the crane, engage the parking brake and shut off
the engine.
3. Check the oil level in the sight gauge (Figure 5-24) on
the side of the tank. Oil should be visible in the gauge. If
not, add recommended oil to the tank until it is visible.
NOTE: The pump used on this crane requires clean
hydraulic oil for proper operation. Contaminated oil
can cause damage to the pump. Before adding any
hydraulic oil to the hydraulic system, be sure the oil
has been filtered through a 10-micron (absolute),
or less, filter.
