1. General Notices for Safety
1-1. Before using the tractor
※ Must read and understand this operator’s manual carefully and
always refer to information and prescriptions outlined in this
manual to prevent all potential health and safety risks.
◆ General information for intended use
z Your tractor is designed and manufactured to pull, to carry, to supply the power a variety of mounted
or towed equipment for agriculture. Do not use the product for other purposes than intended by the
manufacturer and outlined in this manual. Do not use this tractor for light/heavy forestry applications.
z Do not use the product beyond its limits of terrain gradient and stability than outlined in this manual.
Using the tractor beyond these limits may cause a overturning accident.
z Do not use the tractor on higher speeds than allowed by the load of the tractor and road condition.
Always choose a suitable driving speed to maintain the stability of the tractor.
z Do not use the tractor near or on soft verges of canals and brooks or banks and verges that are
undermined by rodents. The tractor may sink sideways and roll-over.
z Do not use the tractor on brittle bridge heads and poor bridge floors. These constructions may
collapse and cause overturning of the tractor. Always check out the condition and carrying
capacity of bridges and ramps prior to engage.
z Do not use the tractor without wearing the seat belt and Roll-Over Protective Structure (ROPS)
during operations where roll-over or tip-over hazards exist. The ROPS will only be fully effective when
the driver remains attached to his/her seat.
z Do not use equipment mounted on the tractor which is not correctly matching and firmly fixed.
Such equipment may increase the risk for roll-over and hit the tractor when coming loose.
z Do not use the tractor in combination with equipment arbitrary, without having consulted the
specific operator’s manual provided with the equipment. This manual alone cannot provide you
with all the information about safety operation of the combination.
z Do not use the tractor beyond its limits of dynamic stability. High speed, abrupt maneuvers, and
fast and short cornering will increase the risk of roll-over.
z Do not use the tractor for overloaded pulling work, in cases where you don’t know if the load will
yield, for instance when pulling stumps. The tractor may flip over when the stump is not yielding.
z Be extremely cautious when working with the tractor on forage silos without lateral concrete walls.
A wide track setting may improve the lateral stability of the tractor.
z Be cautious that the center of gravity of the tractor may increase when the front-end loader is
loaded or the three-point linkage are raised. In these conditions, the tractor may roll-over earlier than
expected.
z Do not step down from the tractor without shutting down the PTO, shifting the transmission
to neutral and applying the parking brake.
zNever remove or modify or change the driver’s protection device or safety device arbitrary.
1-1
z You must take the necessary precautions to always be aware of the possible presence of
bystanders, certainly when maneuvering in confined areas. Keep people away from the tractor during
work. Pay the necessary attention while operating next to public roads or footpaths. Thrown objects
can get projected outside the field and hit unprotected people like bikers or pedestrians. Wait until it is
clear of bystanders.
z Do not violate the local traffic rules related to public roads and highways.
z Do not allow riders on the tractor; do not allow people standing on the access way or step to the
cab when the tractor is moving. Your view to the left will be obstructed and a rider risks to fall from the
tractor during unforeseen or abrupt movements.
z This tractor has only one operator station and is a one man operated vehicle. Other people on or
around the tractor during normal operation are not allowed.
z Always stay clear from implements operating area and especially do not stand between tractor
and trailed vehicle either three-point linkage when operating lift controls; ensure no bystanders
are near these operating areas.
z This tractor may be equipped with a number of sensors to control safety functions. Do not attempt
to bypass any function on the tractor. You will be exposed to serious hazards, and moreover, the
behavior of the tractor may become unpredictable.
z The manufacturer will not be responsible for the damage or safety problems caused by maintenance
or repair with non-genuine parts. It must be requested to use the genuine parts.
z When cleaning the tractor by using high pressurized water, do not inject water directly to the
electronic parts, wiring, air intake pipe, hot engine or muffler inside the bonnet.
z Maintenance and repair of the tractor is performed by skilled technical experts with the proper
tools authorized by the manufacturer.
z For damage or accidents caused by misuse or operation in violation of these rules, the manufacturer
and its distributors will not have any responsibility and warranty.
z Keep this operator’s manual for future reference at hand (on the tractor).

3-3. Hydraulic system
(1) Safety precautions
z Hydraulic oil leaking under pressure can penetrate the skin and cause infection or other injury. To
prevent personal injury, comply with as below.
-. Relieve all pressure before disconnecting hydraulic lines.
-. Before applying pressure, make sure all connections are tight and components are in good
condition.
-. Never use your hand to check for suspected leaks under pressure.
-. If injured by leaking fluid, get medical attention immediately.
z The hydraulic hoses and fittings on your tractor meet engineering specifications for the particular
function. When replacing damaged parts, use only manufacture authorized service parts.
z Care in hydraulic hose installation is a must:
-. Make sure pressure is relieved before starting installation procedure.
-. DO NOT kink or twist a hose, failure may occur. Properly route the hose.
-. Have a certified hydraulic technician install the hose.
-. Remove air from the hydraulic system after installing any hydraulic component.
z Periodically check hydraulic system for leaks or damaged parts - kinked, crushed, flattened, hard
blistered, heat cracked, charred, twisted, soft or loose covered hoses and fittings.
z DO NOT pull or apply external forces to the hose. The hose may fail and cause injury.
z Keep all persons away from the working area. If a hose fails, mechanisms controlled by fluid power
can become hazardous. Lifted mechanisms can fall to the ground, steering system may fail, etc.
z Stay clear of a pressurized hose assembly that has blown apart. Hose fittings can be thrown off at
high speed and a loose hose can whip around with great force.
z Hydraulic oil can reach high temperatures. Allow fluid to cool before servicing the system.
z Vibration can reduce hose service life. Make sure all retaining clamps and/or devices are secured.
z Environmental conditions can cause hose and fittings to deteriorate. Inspect hydraulic hoses
periodically. Replace worn or damaged hoses and fittings.
z Before checking or repairing the hydraulic system, make sure the engine is stopped, and all the
transmission gears are in neutral, and lower the implements to the ground.
Warning ▶Before removing hydraulic pipes or hoses and other parts, make sure to check that
hydraulic pressure is relieved completely. The leaks of pressurized oil can cause a
fatal physical injury.
▶Use proper protection equipments, before servicing hydraulic system.
▶Before connecting or disconnecting the hydraulic quick coupler, lower the
implements to the ground, and check that hydraulic pressure is relieved.

In this case, reduce the size of the load.
2. After turning the steering wheel fully, do not turn the steering wheel to the same direction again. As
the unnecessary force is applied, this could damage to the steering system. Especially, DO NOT
operate the steering wheel excessively. If the front wheel mired in a ditch. In this case, the rim could
be affected and damaged.
3. If it sounds abnormal when operating the steering wheel, this means that there is some air in the
steering components and line. In this case, turn the steering wheel to the left and right fully and hold
it for about 5 seconds, and the air shall bleed out and the abnormal noise shall disappear. If it’s not
cleared, contact your authorized local dealer for repair.
4. When starting engine in cold weather, an abnormal noise may occur. In this case, warm up the
tractor before using to reduce the oil viscosity.
