When making heavy lifts with a high boom, use extreme care and try the load after lifting it off the ground to see
that the brakes will hold the load.
Never move loads over personnel or equipment.
Under no circumstances exceed maximum, permissible speed.
Be sure revolving frame is stopped before attempting to ewe swing lock, and release lock before attempting to
swing the crane.
Keep lift height to minimum when handling close to maximum loads.
Start and stop revolving frame slowly when swinging heavy loads.
Always keep machine stationary and use outriggers when lifting maximum loads.
Be sure there is adequate clearance before attempting to move machine under low objects.
Apply brakes and engage clutches carefully. Sudden engagement of clutches or application of brakes causes
undue strain on the machine.
When traveling across bridges, check to make sure they will carry a load equal to the machine's weight.
Always keep boom at least 10 feet away from all overhead wires.
If boom should hit overhead wires, stay on the machine until boom is cleared or current is shut off. Keep
everyone on the ground away from the machine. If you must leave the machine jump; do not step off.
Always use handline for guiding loads.
Never get on or off a machine in motion.
Check to be sure slings, ties, and hooks are properly placed and secure before raising op" lowering loads.
Stop the engine when greasing, oiling, or making any adjustments to the engine.
Never add coolant to an overheated engine. Allow engine to cool first; then add coolant with the engine running.
Never put a full load or speed on a cold engine.
Make sure the choke valve is wide open when the engine is running at operating temperature.
Do not operate the engine in a closed building unless the exhaust gas is piped to the outside. The exhaust gases
contain carbon monoxide, a colorless, odorless, deadly poison.
Keep hands clear of cables feeding in on sheaves or drums.
Inspect all cables and clamps weekly.
AFTER OPERATION
Never leave a crane overnight with boom raised; lower the boom to the ground.
