and/or oil from the soles of your work boots. If any

controls such as a pedal is operated while with dirt

and/or oil on the soles of the operator’s work boots the

operator’s foot may slip off the pedal, possibly result-

ing in a personal accident.

• Do not leave parts and/or tools lying around the op-

erator’s seat. Store them in their specified locations.

• Avoid storing transparent bottles in the cab. Do not

attach any transparent type window decorations on

the windowpanes as they may focus sunlight, possibly

starting a fire.

• Refrain from listening to the radio, or using music

headphones or mobile telephones in the cab while

operating the machine.

• Keep all flammable objects and/or explosives away

from the machine.

• After using the ashtray, always cover it to extinguish

the match and/or tobacco.

• Do not leave cigarette lighters in the cab. When the

temperature in the cab increases, the lighter may ex-

plode.

524-E01A-0000

SAFETY

S-5

USE HANDHOLDS AND STEPS

• Falling is one of the major causes of personal injury.

• When you get on and off the machine, always face the

machine and maintain a three-point contact with the

steps and handrails.

• Do not use any controls as handholds.

• Never jump on or off the machine. Never mount or

dismount a moving machine.

• Be careful of slippery conditions on platforms, steps,

and handrails when leaving the machine.

008-E01A-0439

ADJUST THE OPERATOR’S SEAT

• A poorly adjusted seat for either the operator or for the

work at hand may quickly fatigue the operator leading to misoperations.

• The seat should be adjusted whenever changing the

operator for the machine.

• The operator should be able to fully depress the ped-

als and to correctly operate the control levers with his

back against the seat back.

• If not, move the seat forward or backward, and check

again.

SA-378

SAFETY

S-6

FASTEN YOUR SEAT BELT

• If the machine should overturn, the operator may be-

come injured and/or thrown from the cab. Additionally the operator may be crushed by the overturning machine, resulting in serious injury or death.

• Prior to operating the machine, thoroughly examine

webbing, buckle and attaching hardware. If any item is

damaged or worn, replace the seat belt or component

before operating the machine.

• Be sure to remain seated with the seat belt securely

fastened at all times when the machine is in operation

to minimize the chance of injury from an accident.

• We recommend that the seat belt be replaced every

three years regardless of its apparent condition.

010-E01A-0237

the machine being operated in an unsafe manner.

014-E01B-0379

SA-379

SAFETY

S-8

INVESTIGATE JOB SITE BEFOREHAND

• When working at the edge of an excavation or on a road

shoulder, the machine could tip over, possibly resulting in serious injury or death.

• Investigate the configuration and ground conditions of

the job site beforehand to prevent the machine from

falling and to prevent the ground, stockpiles, or banks

from collapsing.

• Make a work plan. Use machines appropriate to the

work and job site.

• Reinforce ground, edges, and road shoulders as nec-

essary. Keep the machine well back from the edges of

excavations and road shoulders.

• When working on an incline or on a road shoulder,

employ a signal person as required.

• Confirm that your machine is equipped a FOPS cab

before working in areas where the possibility of falling

stones or debris exist.

• When the footing is weak, reinforce the ground before

starting work.

• When working on frozen ground, be extremely alert.
