OPERATING AND MAINTENANCE INSTRUCTIONS Sheet 4 of 22
1. Safety instructions
This machine is intended for carrying grains, produce, dirt and similar materials. Carrying other objects may
damage machine. Avoid carrying liquid concrete. That will damage machine. The stability of machine is
affected by speed, rate of steering, terrain and load. Always pay close attention to these factors or loss of
control or tipping over could occur, resulting in property damage, serious injury or death.
1.1 General Driving
• Do not operate engine in a confined space where dangerous carbon monoxide fumes can accumulate.
• Do not touch engine, muffler or exhaust pipe while engine is running or soon after it has stopped. These
areas will be very hot and can cause burns.
• Do not operate machine under the influence of alcohol or drugs. Do not operate machine when you are
tired, ill, or not fit to operate machine.
• Before starting engine and moving machine, scan around your surroundings and make sure all persons
and other vehicles are a safe distance away from machine.
• 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.
• Always check for obstacles before operating on new terrain. Travel slowly and use extra caution when
operating on unfamiliar terrain. Be alert when traveling on changing terrain.
• Always hold handle grips with both hands to keep a posture when operating machine.
• Drive at a safe speed, taking into account surface gradient, surface conditions and load.
• Do not make sudden maneuvers. Sudden start, stop, or turn can make machine lose control and could
cause a tip over. Be especially cautious when traveling on soft or wet ground.
• 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 person behind machine when backing up. Make certain
that it is safe to back up, then move slowly and avoid sharp turns.
• To reduce the risk of tipping 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 below.
• Never attempt to drive over a large obstacle such as rock or fallen tree.
• Do not operate machine near the edge of a cliff, an overhang or a landslide area.
• Use an observer to help direct machine when visibility is poor, terrain is rugged or hilly, or maneuvering
room is limited. An observer should be able to see machine and its immediate surroundings, and should
give pre-arranged signals to direct the operator.

OPERATING AND MAINTENANCE INSTRUCTIONS Sheet 5 of 22
1.2 Driving on a Slope
• Driving on a slope can be dangerous. It can result in a tip over and cause serious injury or death. Always
follow proper procedures for driving on a slope as described in this manual.
• When carrying no load, do NOT use machine on a slope steeper than 25 degrees. When carrying a load,
observe the load limit according to the inclination (see Loading and Driving with the Load). Do not dump on
a slope.
• Driving on a slope in a wrong manner can cause a loss of control or a vehicle tip over. Check 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 down a slope, stop and shift to one of the first three gears (auxiliary transmission in Low).
Go down at a reduced speed. Use engine speed to help keep machine speed low.
• When driving up a slope, proceed at a steady rate of speed and throttle position.
• Never move throttle lever or operate side clutch suddenly.
• Drive straight up or down a slope. Avoid turning on a slope. Avoid driving machine across a slope.
• If engine stalls or loses traction during a climb and cannot make it to the top of a slope, do not try to turn
machine around. Carefully back down slowly, straight down 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.
• Without a load, drive machine backwards up a slope (operator's handle toward the top) when climbing,
and drive it forward when going down a slope.
• With a load, drive machine forward up a slope (operator's handle away from the top) when climbing, and
drive it backwards when going down a slope. Be especially cautious when operating on a slope with a load.
1.3 Loading and Driving with a Load
• The maximum payload for this machine is 400kg. Do not exceed this maximum payload under any
circumstance.
• Do not operate on a slope steeper than 20 degrees when carrying a load. Do not carry more than 150kg
when operating on a slope between 15 and 20 degrees.
• Place a load in loading deck so that the weight is evenly distributed. When carrying a load, strap it to
loading deck to prevent it from shifting. Ensure that the load does not obstruct the operator's field of view.
• When carrying a load, drive at a reduced speed. Allow greater distance for braking.
• Before crossing a bridge or an overpass, make certain that the total combined weight of machine, load
and operator is within the stated weight limit of the bridge or the overpass. Then, proceed carefully and at
a constant speed.

OPERATING AND MAINTENANCE INSTRUCTIONS Sheet 6 of 22
1.4 Parking
• Park machine on a flat, level and stable surface. Do not park in a dangerous place. Never park machine
on a slope steeper than 15 degrees. Avoid parking on a slope less than 15 degrees. If parking on a slope
less than 15 degrees is unavoidable, block tracks at the lower end of machine. → Without a load, park
machine with operator's handle uphill → With a load, park machine with operator's handle downhill → Do
not park sideways on a slope.
• Observe all the previous precautions for general driving, driving on a slope, loading and driving with a
load.
• Whenever you park machine, disengage clutch and stop engine.
• Gasoline is highly flammable and can be explosive. When parking machine indoors, make certain that the
building is well ventilated and that machine is not close to any source of flame or spark, including appliances
with pilot lights.
1.5 Servicing
• Do not service machine when engine is running. If it is absolutely necessary to run engine while servicing,
keep hands, feet, clothing and any part of the body away from any moving part, especially belts at the side
of engine.
• Do not operate engine in a confined space where dangerous carbon monoxide fumes can accumulate.
• Check all fuel lines on a regular basis for fit and wear. Tighten or repair them as needed.
• Do not touch engine, muffler, or exhaust pipe while engine is running or soon after it has stopped. These
areas will be very hot and can cause burns.
• Engine must be shut off before checking or adding oil.
