or its equipment. Follow all machine mounted safety signs before starting, operating, maintaining or servicing the
machine. Be sure the area of the operator's compartment, all mounting steps and grab handles are free of oil, grease,
loose objects, ice and mud to lessen the possibility of slipping. Remove or secure all maintenance and personal items
so they will not interfere with the operator or jam the controls.
Perform a visual check of the machine before starting the engine. Look for such things as improper fluid levels, oil leaks,
and loose, damaged or missing parts. Do not start the engine until any unsafe conditions are corrected. Secure all caps
and filler plugs.
Know and understand the traffic flow patterns of your job and obey flagman, signs and signals. Check work area for
hazardous conditions. Be alert for soft ground conditions, especially when working on slopes, near drop offs or
excavations or fill material, which could lead to sudden tipping of the machine. At night and times of poor visibility,
carefully check the work area before moving in with the machine. Use all lights provided.
Before entering the operator's compartment, clear the immediate area surrounding the machine of personnel and
obstructions. Walk completely around the machine. After entering the operator's compartment, sound the horn to clear
the immediate area of the machine.
Due to the danger of fire and explosion, never check or fill fuel tank or batteries near lighted smoking materials or open
flame or sparks.
OPERATION
Before starting the engine, be sure you understand all control functions. Only one person, the operator, should be
permitted to ride on the machine when it is in operation. Never haul passengers. Perform an operational check of the
machine in a safe area before putting it to work. Check all controls, including the brake pedal, steering pedals and
transmission selector. Check all gauges, warning lights and safety devices. Correct any malfunctions. Always sit in the
operator's seat before operating any controls. Keep operating controls, hands and shoes free of grease, water and mud
to insure positive control functions.
The machine is ROPS equipped, for your personal protection, wear your seat belt. In the event of a rollover, stay with
the machine. Experience has shown this will reduce the seriousness or chance of injury. Before driving the machine,
adjust the seat and fasten the seat belt. Adjust the seat belt to fit snugly and flow 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.
Check overhead clearance carefully before operating the machine in areas with low overhead clearance, such as guy
wires, power lines, bridges, low hanging tree branches and building entrances or exits. These overhead obstructions
could cause an accident.
Never start the engine indoors unless proper exhaust ventilation is provided to remove deadly exhaust gases. Once the
engine is operating, move the machine outdoors as soon as possible. Exhaust gases are dangerous and cause
unconsciousness and death. Never operate the engine at more than the regular governed speed shown in the
OPERATION & MAINTENANCE MANUAL. Excessive speeds are harmful and dangerous.
After starting the engine, but before moving the machine, warn nearby personnel by giving a couple of short horn blasts.
When operating the machine, look in the intended direction of travel to be sure personnel or allied equipment does not
interfere with the machine work pattern. Never try to get on or off the machine while it is moving. A serious injury or death
could result.
Never mix gasoline, gasohol and/or alcohol with diesel fuel. This practice creates an extreme fire hazard and under
certain conditions an explosion which could result in personal injury or death. Never remove the fuel tank filler caps or
refill the fuel tanks while the engine is running or hot or when the machine is indoors. Fumes are dangerous, a spark
or flame could result in a fire or explosion.
Avoid sidehill travel whenever possible. Drive straight up and down the slope. If the machine starts slipping sideways
on a grade, turn downhill immediately. Be careful and alert when operating sideways on a steep slope as a rollover and
serious injuries could result. There is no substitute for good judgement when working the machine on a slope.
If possible avoid crossing obstacles such as ridges, rocks or logs. If you can't avoid them, reduce speed and ease over
the obstacle at an angle.
