WARNING
Operators must be thoroughly familiar with safe crane operating practices and have a complete understanding of all
operation and maintenance instructions provided. Operators should be physically fit and thoroughly trained, with related
experience, not be easily excitable, not be subject to epileptic seizures, and not be using any drug that could impair
physical, visual, or mental reactions or capabilities.
Wear the proper clothing for the job. Wear personnel protective equipment as required by local or job regulations.
Perform all Preventive Maintenance Services and Checks (PMCS). Refer to Chapter 5. Ensure that routine
maintenance and lubrication are being dutifully performed. Don't' operate a damaged or poorly maintained crane. You
risk lives when operating faulty machinery, including your own.
Know the area in which you are working. Familiarize yourself with work site obstructions and other potential hazards in
the area.
Use caution when in the vicinity of overhanging banks or edges.
Keep your shoes clean. Before entering the cab, clean any mud or grease from your shoes. This will reduce the
possibility of your foot slipping off a control pedal, possible resulting in an accident.
Since certain shoe sole materials are more slip resistant than others, all operating and service personnel should wear
footwear with high slip resistant sole material.
Avoid a dirty or greasy crane. Keep the cab, deck, and foot and hand holds free of mud and grease for operator safety.
Dirty equipment fails rapidly and makes good maintenance difficult.
Observe and heed possible pinch points while performing maintenance or other work.
Check for WARNING tags placed on the crane. If found, refuse to operate the crane until repairs are made and
WARNING tags are removed by authorized personnel.
Before performing maintenance, disconnect the battery, remove the ignition key, and place WARNING SIGNS in the
cab.
BEFORE performing maintenance on the crane, remove all weight from outrigger jack cylinders, and lower attachments
to the ground or place them on suitable blocking.
Pressurized air and hydraulic oil can cause serious injury. Be certain all lines, components, and fittings are tight and
serviceable. Use a piece of cardboard or wood to search for suspected leaks in hydraulic systems and soapy water to
search for leaks in pneumatic systems.
Always replace the guards or other safety devices which may have been removed during crane repair or adjustment.
