Shut-Down
Never leave the crane with a load suspended. Lower the
load to the ground before shutting down the crane.
Use the following steps when shutting down the crane:
• Engage the parking brake.
• Fully retract and lower the boom.
• Place controls in neutral position.
• Shut down the engine and remove the ignition key.
• Lock the truckcab and install vandal guards, if used.
In cold weather, never park the crane where the tires can
become frozen to the ground.
Boom Extension/Jib
To avoid death or serious injury, follow proper procedures
during erection, stowage, and use of the boom extension/jib.
Install and secure all pins properly.
Control movement of boom extension/jib at all times.
Do not remove right side boom nose pins unless boom
extension is properly pinned and secured on front and/or
rear stowage brackets.
Do not remove all the pins from both front and rear stowage
brackets unless the boom extension is pinned to the right
side of the boom nose.
See the appropriate section of this handbook for the proper
boom extension/jib erection and stowage procedure.
Properly inspect, maintain, and adjust boom extension/jib
and mounting.
Sling jib sections from the main chords or the end fittings.
When assembling and disassembling jib sections, use
blocking to adequately support each section and to provide
proper alignment.
Stay outside of jib sections and lattice work.
Watch for falling or flying pins when they are being removed.
Cold Weather Operation
Cold weather operation requires additional caution on the
part of the operator.
Check operating procedures for cold weather starting.
Don't touch metal surfaces that could freeze you to them.
Clean the crane of all ice and snow.
Allow ample time for hydraulic oil to warm up.
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.
If applicable to your crane, frequently check all air tanks for
water in freezing weather.
If applicable to your crane, always handle propane tanks
according to the supplier's instructions.
Never store flammable materials on the crane.
If cold weather starting aids are provided on your crane, use
them. The use of aerosol spray or other types of starting
fluids containing ether/volatiles can cause explosions or fire,
and should not be used on engines with electric intake
heaters.
