OPERATING MACHINE

1

WHEN STARTING ENGINE

1
• Perform a visual check of the machine before starting the engine. Look for such things as missing protective devices, leaks,
improper fluid levels, trash buildup and loose, damaged or missing parts. Do not start the engine until any unsafe conditions
are corrected.
• Walk around the machine again just before mounting it, checking for people and objects that might be in the way.
• Never start the engine if a warning tag has been attached to the control.
• Understand all control functions before starting the engine.
• When starting the engine, sound the horn as an alert
• Start and operate the machine only while seated.
• Do not allow anyone other than the operator to ride in the operator's compartment or on the machine body.
• For machines equipped with a back up alarm, check that the warning device operates correctly.
• Keep hands and footwear free of grease, water and mud to insure positive control movement.
• Before driving the machine, adjust the seat and fasten the seat belt. Adjust the seat for maximum comfort and control of the
machine. Adjust the seat belt to fit snugly and low around the hips to lessen the chance and severity of injury in the event of
an accident. Never wear the seat belt across the abdomen.
• Before moving the machine, check the brakes, steering, equipment controls and safety devices such as the back up alarm for
proper operation. Do not operate the machine until any unsafe conditions have been corrected.

PRECAUTIONS WHEN MOVING FORWARD OR BACKWARD

1
• When operating in areas that may be hazardous or have poor visibility, designate a person to
direct work site traffic.
• Be sure no one is around machine, particularly behind machine.
• Before starting machine motion, sound horn to alert people.
• There is a blind spot behind the machine. Make sure that nobody is present behind it before
driving the machine backward.

VISIBILITY

1
• Turn on the head lamps and working lamp, when working at night or at dark sites. Provide additional lighting for the work
site if necessary.
• If visibility is diminished by fog, snow or rain, stop operation. Wait until there is adequate visibility for safe operation.

TRAVELING ON SLOPES

1
• Traveling on hills, banks or slopes that are steep could result in the machine tipping over or
slipping.
• On hills, banks or slopes, carry the mounted equipment closer to the ground. Approximately
20 to 30 cm (8 to 12 in) above the ground. In case of emergency, quickly lower the mounted
equipment to the ground to help the machine stop and prevent it from tipping over.
• Do not change directions on slopes. Avoid sideways travel whenever possible: rather travel
up and down the slopes.
• Do not travel up and down on grass, fallen leaves, and wet steel plates. These materials may
allow the machine to slip, if it is traveling sideways. Keep travel speed very low.
• When traveling downhill, drive slowly and use the engine as a brake.
• When traveling downhill with the machine being pushed by its own weight, the machine
may steer in the opposite direction, so be careful.
