100°F) will help the oil penetrate into the wire rope. Use
a brush or cloth to apply the oil.
NOTE: Be sure the lubricant enters the strands of the wire
rope for proper lubrication. Do not use grease to
lubricate the wire rope.
Lubricate the Swing Gear and Pinion
1. Engage the parking brake and shut off the engine.
2. Remove both guards covering the swing gear and
pinion.
• Rotating gears can cause injury. Keep hands clear of
rotating pinion and gear while the mast is rotating.
3. Using a brush, apply open gear lube to the pinion and
swing gear teeth (Figure 5-44).
4. Start the engine and rotate the mast through several
complete cycles to distribute the lubricant evenly.
5. Shut off the engine.
6. Install the guards over the exposed pinion and swing
gear.
Replace the Crankcase Oil and Filter
Change the engine oil more frequently if operating under
difficult conditions, for example in high or low temperatures,
dusty surroundings or frequent starting and stopping.
NOTE: It is necessary to climb under the crane to change
the engine oil and replace the engine oil filter. Be
sure engine is shut off, the ignition key is removed
and chock blocks are in place before climbing
under the crane.
NOTE: Drain the engine oil only when it is hot and the
contaminants are in suspension.
NOTE: Hot oil can cause personal injury.
1. Operate the engine until the water temperature reaches
60°C (140°F).
2. Shut off the engine.
3. Place a suitable container under the engine oil drain
plug. Remove the oil drain plug.
4. Clean the area around the engine oil filter head.
5. Remove the filter and clean the gasket surface of the
filter head.
NOTE: The O-ring can stick on the filter head. Make sure it
is removed before installing the new filter.
6. Fill the new filter with clean recommended lubricating oil
(See the engine manual furnished with the crane).
7. Apply a small amount of clean engine oil to the gasket of
the new oil filter. Turn the filter clockwise to tighten it until
the gasket makes contact. Then, tighten the filter 1/2 to
3/4 turn to get correct seal.
8. Fill the engine crankcase with clean recommended
lubricating oil.
9. Operate the engine at idle and inspect for leaks at the
filter and drain plug
