SAFETY INFORMATION
When moving in tight quarters, post a signal person to help
guard against collisions or bumping structures.
Before traveling a crane, check suitability of proposed route
with regard to crane height, width, and length.
Never back up without the aid of a signal person to verify the
area behind the crane is clear of obstructions and/or
personnel.
On cranes equipped with air-operated brakes, do not attempt
to move the crane until brake system air pressure is at
operating level.
Check load limit of bridges. Before traveling across bridges,
ensure they will carry a load greater than the crane's weight.
If it is necessary to take the crane on a road or highway,
check state and local restrictions and regulations.
Drive carefully and avoid speeding.
Stay alert at the wheel.
When parking on a grade, apply the parking brake and chock
the wheels.
Maintenance
The crane must be inspected prior to use on each work shift.
The owner, user, and operator must ensure that routine
maintenance and lubrication are being dutifully performed.
NEVER operate a damaged or poorly maintained crane.
Keep the crane properly maintained and adjusted at all
times. Shut down the crane while making repairs or
adjustments.
Always perform a function check after repairs have been
made to ensure proper operation. Load tests should be
performed when structural or lifting members are involved.
Follow all applicable safety precautions in this handbook
when performing crane maintenance as well as crane
operations.
Before crane use:
• Conduct a visual inspection for cracked welds, damaged
components, loose pin/bolt, and wire connections. Any
item or component that is found to be loose or damaged
(broken, chipped, cracked, worn-through, etc.) must be
repaired befor operation. Check for proper functioning of
all controls and operator aids (e.g. HCAS).
• Check all braking (e.g. wheel, hoist, and swing brakes)
and holding devices before operation.
Keep the crane clean at all times, free of mud, dirt, and
grease. Dirty equipment introduces hazards, wears-out
faster, and makes proper maintenance difficult. Cleaning
solutions used should be non-flammable, non-toxic and
appropriate for the job.

crane booms.
After maintenance or repairs:
• Replace all guards and covers that have been removed.
• Remove all tags, connect the battery, and perform a
function check of all operating controls.
• Perform load tests when a structural or lifting member is
involved in a repair.
Lubrication
The crane must be lubricated according to the factory
recommendations for lubrication points, time intervals, and
types. Lubricate at more frequent intervals when working
under severe conditions.
Exercise care when servicing the hydraulic system of the
