Get medical attention immediately.

IMPORTANT! In case of internal contact, DO NOT give fluids that would induce vomiting!

5. Moving Parts Hazard

DO NOT place limbs near moving parts. Severing of any body part can result.

Turn off engine and wait until fan and belts stop moving before servicing.

OS0042

6. Lowering Boom or Falling Load Hazard

DO NOT get under a raised boom unless it is blocked up safely. Always empty the attachment of any load and block the boom up before doing any servicing that would require the boom to be raised.

NEVER allow anyone to walk or stand under the boom. A lowering boom or falling load can result in serious injury or death.

3606 Rev 11/99

Safety Practices

Operational Considerations

1. Preperation and Prevention

Know the location and function of all vehicle controls.

Make sure all persons are away from the vehicle and that the Travel Select Lever is in the (N) NEUTRAL position with the parking brake switch engaged before starting the engine.

Holes, obstructions, debris and other worksite hazards can cause injury or death. Always walk around and look for these and other hazards before operating the vehicle on a new worksite.

Prevent accidents when you move the vehicle around the worksite. Know the rules for movement of people and vehicles on the worksite. Follow the instructions of signals and signs.

DO NOT operate the vehicle unless:

•all safety equipment is in proper working condition,

•all covers and guards are in place, and

•all safety and instructional decals are in place and readable. (Replace all missing, illegible, or damaged decals.)

2.Clearances

Look out for and avoid other personnel, machinery and vehicles in the area. Travel with the boom fully retracted and lowered as far as possible while still maintaining enough ground clearance for conditions.

Always check boom clearances carefully before driving underneath door openings, bridges, etc.

Always check for power lines when raising the boom. Beware of overhead wires, contact with electrical power lines can result in electrocution. See “Electrocution Hazards” on page 9.

3. Underground Hazards

Know the location of all underground hazards before operating this vehicle in a new area or worksite. Electrical cables, gas and water pipes, sewer, or other underground objects can cause injury or death. Contact your local underground utility service or diggers hotline to mark all underground hazards.

8	3606 Rev 11/99

Safety Practices

4. Electrocution Hazards

NEVER operate this vehicle in an area where overhead power lines, overhead or underground cables, or other power sources may exist without first requesting that the appropriate power or utility company deenergize the lines, or take other suitable precautions.

OS0063

5. Carrying Personnel

Use only an approved work platform for lifting and lowering personnel. NEVER transport personnel in a work platform for even the shortest distance.

Serious injury or death can occur if these rules are not obeyed. Riders can fall and be crushed or run over. Avoid accidents.

For other specific precautions, see “Elevating Personnel” on page 76.

OS0072

OS0631

3606 Rev 11/99

Safety Practices

6. Tip Over Hazard

OS1633

MAINTAIN proper tire pressures at all times. Underpressurized tire(s) adversely affects vehicle stability. If proper tire pressures are not maintained, this vehicle can tip over. If a vehicle ever becomes unstable and starts to tip over:

•BRACE YOURSELF and STAY WITH THE VEHICLE,

•KEEP YOUR SEAT BELT FASTENED,

•HOLD ON FIRMLY and

•LEAN AWAY FROM THE POINT OF IMPACT.

Indecision and trying to escape from a tipping vehicle can result in death or serious injury.

To ensure proper vehicle stability, check all four tire pressures before operating the vehicle. Maintain proper tire pressures.

DO NOT exceed the rated lift capacity of the vehicle as structural damage and unstable conditions will result.

To ensure that the vehicle is positioned in the most stable condition before operating an attachment:

Use the sway control to level the vehicle. The vehicle is level when the frame level indicator gauge reaches (0°) zero degrees. If the vehicle cannot be leveled using the sway control, reposition the vehicle.

Keep the vehicle under control at all times. When negotiating turns, slow down and turn the steering wheel in a smooth sweeping motion. Avoid jerky turns, starts or stops. Reduce vehicle speed on rough ground and slopes.

10	3606 Rev 11/99

Safety Practices

OS0083

Travelling with the boom raised is dangerous and can cause tipover. Keep the boom as low as possible. Travel with extreme caution and at the slowest possible speed.

Swaying (frame tilt) left or right with the boom raised above horizontal is dangerous. Always use the sway control to level the vehicle before raising the boom above horizontal, with or without a load. If the vehicle cannot be leveled using sway control, reposition the vehicle.

7. Slopes

DO NOT park the vehicle on an incline and leave it unattended.

•Driving across a slope is dangerous, as unexpected changes in the slope can cause tipover. Ascend or descend slopes slowly and with caution.

•Ascend or descend slopes with the heavy end of the vehicle pointing up the slope.

NOTE: The rear of the vehicle is normally considered the heavy end unless the carriage is fully loaded. In this case the front of the vehicle is now the heavy end.

•Unloaded vehicles should be operated on all slopes with the carriage pointing down the slope.

•On all slopes, the load must be tilted back and raised only as far as necessary to clear the ground.

•When operating on a downhill slope, reduce travel speed and downshift to a low gear to permit compression braking by the engine and aid the application of the service brakes.

3606 Rev 11/99

11

Safety Practices

8. 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 “Fork Rating” on page 75.

DO NOT downshift at a high ground speed. Sudden slowing can cause the load to drop off the forks.

9. Visual Obstruction

Dust, smoke, fog, etc. can decrease vision and cause an accident. Always stop or slow the vehicle until the obstruction clears and the worksite is visible again.

10. 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.
