OH1650

Safety Practices

Model 10054 Rev. 11/03

C. Ether or High Energy Starting Aids

The engine utilizes a grid heating system inside the induction

manifold for cold starting conditions.

DO NOT use ether or any

other high energy starting

aids during cold starting. An

engine explosion can result

in death or serious personal

injury.

D. Hydraulic Fluid

DO NOT attempt to repair or tighten any hydraulic hoses or fittings

while the engine is running or when the hydraulic system is under

pressure. Fluid in the hydraulic system is under enough pressure

that it can penetrate the skin causing death or serious personal

injuries.

HOT HYDRAULIC FLUID WILL CAUSE SEVERE BURNS. Wait

for fluid to cool down before disconnecting lines.

DO NOT use your hand to check for leaks. Use a piece of

cardboard or paper to search for leaks. Wear gloves to protect

hands from spraying fluid.

Hydraulic fluid can cause permanent eye injury. Wear appropriate

eye protection and stop engine. Relieve pressure before

disconnecting lines by moving all joysticks back and forth through

all functions.

If anyone is injured by or if any hydraulic fluid is injected into the

skin, obtain medical attention immediately or gangrene may result.

WARNING: This diesel engine uses a grid heating system

inside the induction manifold. DO NOT use ether or any high

energy fuels to assist starting. An explosion may cause death or

serious personal injury or engine damage.

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

would induce vomiting!

Safety Practices

Model 10054 Rev. 11/03

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.

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 death or serious personal injury.

MOVING PARTS can cut.

Keep clear of fan and belts

while engine is running.

MOVING PARTS can entangle.

OT0810

Model 10054 Rev. 11/03

Safety Practices

1. Preparation 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 death

or serious personal injury. Always walk around and look for these and

other hazards before operating the vehicle in 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.

Have a person act as a lookout for you. Follow the instructions of

signals and signs.

DO NOT operate the vehicle unless all hazard 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. Use a spotter if you do not have a clear view of conditions that

affect clearances. 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 15.

3. 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. Have a lookout person assist you.

Where the load will obstruct the operator’s vision, it is recommended

that the vehicle be operated in REVERSE, looking backwards in the

direction of travel. Travel at a slower speed and get someone to direct

you.

Operational Considerations

Safety Practices

Model 10054 Rev. 11/03

4. 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 death or serious

personal injury. Contact your local underground utility service or diggers

hotline to mark all underground hazards.

5. 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 de-

energize the lines, or take other suitable precautions.

OS0063

Model 10054 Rev. 11/03

Safety Practices

6. Elevating Personnel

Use only a compliant work platform meeting the ASME B56.6 standards

for lifting and lowering personnel. NEVER transport personnel in a work

platform for even the shortest distance.

Death or serious personal injury 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 90.

7. Tip Over Hazard

Traveling 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.

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.

Safety Practices

Model 10054 Rev. 11/03

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 frame sway control (frame tilt)

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 frame sway control, reposition

the vehicle.

Frame swaying left or right with the boom raised above horizontal is

dangerous. Always use the frame sway control to level the vehicle

before

raising the boom above horizontal, with or without a load. If the

vehicle cannot be leveled using frame sway control, reposition the

vehicle.

Lowering outriggers over holes or on soft terrain can compromise the

stability of the vehicle which could result in vehicle tipover. For optimum

stability, lower the outriggers just far enough until the front of the vehicle

starts to raise and maintains a firm footing.

NEVER attempt to move the vehicle after the outriggers have been

lowered.

4107971

DANGER

VEHICLE TIPOVER, outriggers

over holes or voids can cause

8. Emergency Exit Rear Window

The rear window (1) in the enclosed cab can be used as an emergency

exit by removing the latch pin (2) located on the window latch (3). The

window is then free to swing open.

9. Tire Pressure

MAINTAIN proper tire pressures at all times. An underpressurized

tire(s) adversely affects vehicle stability. If proper tire pressures are not

maintained, this vehicle can tip over.

To ensure proper vehicle stability, check all four tire pressures before

operating the vehicle.

10.Do Not Jump

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 personal injury.

11.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.

A red LED, on the parking brake switch, and a light in the instrument cluster

will indicate the brake is ENGAGED.

The parking brake may be used to stop in an EMERGENCY situation.

However, use caution because the stop will be abrupt and the operator and

the load may be jolted forward unexpectedly.

With boom angles greater than 40°, this switch activates the locked mode of

the Stabil-TRAK system.
