WARNING AVOID OVERLOADING THE AIR BOX WHEN USING THE QUICK START BUTTON. DO NOT ATTEMPT MORE THAN THREE CONSECUTIVE STARTS WITHOUT ALLOWING THE QUICK START FLUID TO DISSIPATE. OTHERWISE, AN OVERLOADING OF THE AIR BOX WITH HIGHLY VOLATILE FLUID AND A MINOR EXPLOSION COULD OCCUR. WARNING ALWAYS SET THE PARKING BRAKE WHEN THE TRANSMISSION IS DISENGAGED. WARNING DO NOT DRIVE THE CRANE WITH THE BOOM OFF CENTER AS AUTOMATIC OSCILLATION LOCKOUT WILL OCCUR, MAKING THE CRANE SUBJECT TO TIPPING ON UNEVEN SURFACES. DO NOT DRIVE THE CRANE WITH THE LIFT CYLINDERS BOTTOMED. POSITION THE BOOM TO HORIZONTAL. WARNING DO NOT TRAVEL WITH AN EMPTY HOOK IN A POSITION WHERE IT CAN SWING FREELY. IF NOT REQUIRED TO PERFORM AN ON-RUBBER LIFT, THE BOTTOM LIFT SLING MUST BE REMOVED FROM ITS ON CRANE STOWAGE CRADLE FOR ALL ON RUBBER LIFTS. WARNING WHEN PERFORMING AN ONRUBBER LIFT AFTER MOVING THE CRANE, ALLOW THE TIRES TO COOL BEFORE LIFTING ANY LOADS WITH THE OUTRIGGERS RETRACTED. FAILURE TO FOLLOW THIS WARNING COULD RESULT INA TIRE EXPLODING CAUSING PERSONNEL INJURY AND/OR EQUIPMENT DAMAGE. WARNING AVOID HOLES, ROCKS, AND EXTREMELY SOFT SURFACES, AND ANY OTHER OBSTACLES WHICH MIGHT SUBJECT THE CRANE TO UNDUE STRESSES OR POSSIBLE OVERTURN. WARNING ON OPEN GROUND, TOW OR PULL ONLY ON THE PINTLE HOOK OR LIFT LUGS.

WARNING THE ENGINE MUST BE SHUT DOWN BEFORE ATTEMPTING TO ENGAGE THE HYDRAULIC PUMP DRIVE. WARNING THE OUTRIGGERS MUST BE FULLY EXTENDED AND SET BEFORE ANYOTHER OPERATION OF THE CRANE IS ATTEMPTED, UNLESS LIFTING ON RUBBER. WARNING EACH OUTRIGGER FLOAT WEIGHTS APPROXIMATELY 90 POUNDS (40 .8 KG) . USE TWO PEOPLE TO CAREFULLY REMOVE AND INSTALL EACH OUTRIGGER FLOAT ON MOUNTING STUDS.

FAQs

What conditions allow crane operations near overhead power lines?

Operations adjacent to overhead lines are prohibited unless power is shut off and positive means are taken to prevent energizing, and required clearance distances by voltage class are maintained.

What must be checked before starting the engine?

Ensure the parking brake is applied and the swing lock is engaged before starting the engine.

What safety rules apply during boom swing and boom elevation/lowering?

Before swing, confirm the swing path of the hook/load and tail swing area are clear of obstructions and personnel; stop swing immediately if the “Elevate Boom” message appears and elevate to clear the engine hood. During lowering, let out the cable(s) simultaneously to prevent two-blocking the boom nose and hook block(s).
