CAUTION
Proper lubrication is a requirement in any heavy equipment operation. Follow the factory recommendations regarding
the lubrication time intervals and types of lubricants used. Adjust time intervals accordingly, when working under severe
conditions.
When adding oil to the hydraulic system, follow the manufacturer's recommendations. Mixing the wrong fluids could
destroy seals, causing machine failure.
When performing maintenance, refer to the appropriate manual for instructions. Consult the factory if there are any
questions regarding procedures or specifications.
Do not attempt repairs you do not understand! Never exceed the manufacturer's recommended relief valve pressure
settings.
Maintain battery electrolyte at the proper level. Check the state of charge indicator with a flashlight.
Keep the crane properly maintained and adjusted at all times. Shut down the crane while making repairs or adjustments.
Keep brakes properly adjusted. Keep brake linings free of oil and grease. Do not over lubricate the bearings or brake
anchor pins. Refer to the Preventive Maintenance Checks and Services (PMCS), Section 5.
Inspect the tires for nicks and cuts, imbedded stones, and abnormal wear. Ensure all lug nuts are properly torqued.
In freezing weather, park the crane in an area where it cannot become frozen to the ground.
The drive line can be damaged when attempting to free a frozen crane.
2-2. TRAVEL OPERATION.
WARNING
Check load limit of bridges. Before traveling across bridges, ensure they will carry a load greater than the crane's weight.
Watch clearances when traveling. Do not take a chance of running into overhead or side obstructions.
Never back up without the aid of a signalman to verify the area behind the crane is clear of obstructions and/or
personnel.
When traveling, the boom should be completely retracted, lowered, and stowed in its travel position.
Secure the hook block and other items before moving the crane.
