Replacing Fuel Filter
See the engine operator’s manual furnished with the crane
and follow the replacement procedures.
NOTE: If the filter is not filled with fuel prior to installation,
the engine will not start due to air in the fuel
system. The fuel system will have to be bled as
instructed in the engine operator’s manual
furnished with the crane.
Adding Rust Inhibitor to Engine Cooling System
For maximum protection of the engine cooling system, add a
corrosive inhibitor to the radiator. When the engine is cold,
remove the radiator cap and pour the inhibitor in the radiator
reservoir.
Lubricate the Outrigger Slides
1. Extend and lower the outriggers.
2. Clean the slide beams, top and bottom, with a suitable
solvent.
3. Apply Mobil EP grease, or equivalent, to the areas
shown in Figure 5-54. Do not over lubricate. Extend and
retract the beams several times to spread the grease.
Add Grease to the Swing Gearbox
NOTE: It is necessary to climb under the crane to add
grease to the swing gearbox. Be sure engine is
shut off, the ignition key is removed and chock
blocks are in place before climbing under the
crane.
The grease fitting for adding grease to the swing gearbox
can only be reached from under the crane. It will be
necessary to use a light to see the fitting.
1. Lower the boom, engage the parking brake and shut off
the engine. Remove the ignition key.
2. Clean the grease fitting (Figure 5-55), located on the
swing gearbox housing.
3. Clean around the check plug, located below the gearbox
mounting flange. Remove the check plug.
