Safety Practices
13. Falling Load Hazard
DO NOT exceed the total rated load capacity of the specific type fork being
used. Each fork is stamped with a maximum load capacity. If the capacity is
exceeded, forks may break. See ìFork Ratingî on page 70.
DO NOT downshift at a high ground speed. Sudden slowing can cause the load
to drop off the forks.
14. Ventilation
Sparks from the electrical system and the engine exhaust can cause an
explosion. DO NOT operate this vehicle in an area with flammable dust or
vapors unless good ventilation has removed the hazard.
Carbon monoxide fumes from the engine exhaust can cause suffocation in an
enclosed area. Good ventilation is very important when operating this vehicle.
DO NOT by-pass or disconnect any electrical or hydraulic circuits. Consult the
JLG Service Department or your local Lull Distributor if any circuit is
malfunctioning.
DO check for frayed or cut seat belt webbing, damaged buckles or loose
mounting brackets. Replace immediately if required.
ALWAYS wear a seat belt when operating the vehicle.
DO check tire pressure on all four tires. Add air if required.
DO check the condition of all four rims. Check for bent flanges and/or bead
mounting areas.
DO check the parking brake/transmission de-clutch operation. Refer to the test
procedures on page 171. Repair immediately if required.
DO keep all non-skid surfaces clean and free of debris. Replace if worn,
damaged or missing.
DO check the condition of decals. Replace decals if missing, damaged or
illegible. The following pages show the proper location of the decals.
Equipment Considerations
WARNING:
DO NOT modify or alter (weld, drill, etc.) any part of
this vehicle without first consulting JLG. Modifications can weaken the
structure creating a hazard that can cause death or serious personal
injury.
