The stability of the machine is affected by the speed, rate of steering, terrain and the operator's weight. Always
pay close attention to these factors or a loss of control or tip over could occur, resulting in property damage,
serious injury or death.
General Driving
• Do not operate the engine in a confined space where dangerous carbon monoxide fumes
can accumulate.
• Do not touch the engine, muffler or exhaust pipe while the engine is running or soon after
it has stopped. These areas will be very hot and can cause burns.
•Do not operate the machine under the influence of alcohol or drugs. Do not operate the
machine when you are tired, ill, or not feeling well.
• Always check for obstacles before operating on new terrain. This includes overhead
obstacles such as the branches of a tree.
• Before starting the engine and moving the machine, scan around your surroundings and
make sure all persons and other vehicles are a safe distance away from the machine.
• On a slippery surface, travel slowly and exercise caution to reduce the chance of skidding
or sliding out of control. Never operate on ice.
• Always make certain that there is no obstacle or a person behind the machine when
backing up. After confirming that it is safe to back up, move slowly and avoid sharp turns.
•To reduce the risk of tip over, pay special attention when encountering an obstacle or a
slope, or when braking on a slope or during a turn. See Driving on a Slope on the next
page.
•Never attempt to drive over a large obstacle such as rock or fallen tree.
• Always travel slowly and use extra caution when operating on unfamiliar terrain. Be alert
when traveling on changing terrain.
•Never operate on terrain that you are not comfortable with. Avoid terrain that is so rough,
slippery or loose that you feel like you could tip over.
Page 13

Safety
– 7 –
• Do not operate the machine near the edge of a cliff, an overhang or a slide area. Pay
special attention after heavy rain or earthquake.
• Do not make sudden maneuvers. A sudden start, stop, or turn can make the machine
lose control and could cause a tip over. Be especially cautious when traveling on soft or
wet ground.
•Drive at a safe speed, taking into account the surface gradient, surface conditions and
load.
Driving on a Slope
• Always follow proper procedures for driving on a slope as described in this manual.
•Driving on a slope in a wrong manner can cause a loss of control or a vehicle tip over.
Check the terrain carefully before attempting to drive on a slope.
•Never drive on a slope that you are not comfortable with. Avoid a slope that is so rough,
slippery, or loose that you feel like you could tip over.
• When driving up a slope, proceed at a steady rate of speed and throttle position.
•Never move the throttle lever, the drive lever, the drive pedal or the steering wheel suddenly.
• If the engine stalls or loses traction during a climb and cannot make it to the top of the
slope, do not try to turn the machine around. Carefully back down slowly, straight down
the slope.
•Drive straight up or down slopes. Avoid turning on a slope.
• When going over the top of a slope, go slow; an obstacle, a sharp drop, or another vehicle or person could be on the other side of the crest.
•Avoid driving the machine across a slope.
• Before driving down a slope, stop and shift auxiliary transmission to [LOW] position.
Drive slowly. Use the engine speed to help keep the machine speed low.
•Never use on a slope steeper than 15 degrees.
•Driving on a slope can be dangerous. It can result in a tip
over and cause serious injury or death. Take the following
precautions.

Cutting
When conducting cutting operation, take the following precautions.
• Always follow the proper procedures for cutting as described in this manual.
• Shutt off the work site. Post signs to inform of the cutting operation. Close off the site with
rope if necessary to keep people, especially children, off the work site.
•Pay attention to the surrounding area. Rotating cutting bladethrows stones, rocks and
debris. This may cause property damage, injury, or death.
•Drive forward when cutting. This best prevents the cutting blades from throwing stones,
rocks, or debris.
•Pay attention to obstacles. This includes overhead obstacles such as the branches of a
tree.
Parking
•Park the machine on a flat, level and stable surface. Never park on a slope steeper than
10 degrees. Avoid parking on a slope less than 10 degrees. If parking on a slope less
than 10 degrees is absolutely unavoidable, apply the parking brake and block the wheels
at the lower end of the machine.
» Park the machine facing uphill
» Do not park sideways on a slope.
•Never park on an instable surface. Do not park near the edge of a cliff.
• Observe all the previous precautions for driving, driving on a slope, loading and driving
with a load, and dumping.
• Whenever you park the machine, apply the parking brake and stop the engine. Remove
the key whenever you leave the machine unattended to prevent unauthorized use or accidental starting.
• Gasoline is extremely flammable and can be explosive. When parking the machine
indoors, make certain that the building is well ventilated and that the machine is not close
to any source of flame or spark, including appliances with pilot lights.
3.1.4 Servicing
• Do not service the machine when the engine is running. If it is absolutely necessary to
run the engine while servicing, pay attention to the moving parts.
• Do not operate the engine in a confined space where dangerous carbon monoxide fumes
can accumulate.
• Make sure all hydraulic line connectors are tight and all hydraulic hoses and lines are in
good condition and leak-free.
•Keep your body and hands away from pinhole leaks or nozzles that eject hydraulic fluid
under high pressure. Use paper or cardboard, not your hands, to search for leaks.
Hydraulic fluid escaping under pressure can have sufficient force to penetrate the skin
and cause serious injury.
• Check all fuel lines on a regular basis for tightness and wear. Tighten or repair them as
needed.

10. Transporting
When loading or unloading machine onto or from truck, follow the procedures below.
1. Prepare running boards with enough strength (enough to hold the combined weight of machine and operator),
width (twice the width of tire width), length (more than four times as long as the height of truck's loading
deck), and non-skid surface. Place boards as shown below so that boards stay firmly in their positions even
when machine rides on them.
2. Securely hook running boards to loading deck of truck so that there is no step in height between boards and
truck's loading deck.
Transporting
– 56 –
• Do not allow any one to come near machine, truck, and run-
ning board while loading or unloading machine.
• Do not turn on the running boards. Machine may drop off the
running boards.
• When moving up or down running boards, drive machine
slowly at low speed.
DANGER
When machine is moving over the joint between loading deck of
truck and running board, beware of the shift in machine's center
of gravity. It can move suddenly.
CAUTION
