304G2 SERIES TRACTOR OPERATION MANUAL
7
in mind.
2. Engage clutch gradually. Abrupt engagements,
particularly if pulling out of a low area, a ditch or
muddy grounds, or driving over a steep gradient,
may cause dangerous tractor pitching. Immediately
disengage the clutch if the front wheels tend to
come off the ground.
3. When coasting downhill, keep the transmission
gear engaged. Never disengage the clutch and
never drive your tractor in neutral.
4. When tractor is in motion, the operator should be
correctly seated in the driver’s seat.
5. Do not get on or off a moving tractor.
6. Keep all children and nonessential personnel off
tractors and all equipment.
7. Always press the brake pedal gently.
8. Reduce speed when turning, applying individual
brakes, or operating around hazard on rough
ground or steep slopes.
9. Always operate the tractor at a safe speed for the
type of ground being worked. When operating on
rough ground, use proper caution to assure tractor
stability.
10. When working on sloping grounds (i.e. hillsides)
drive at moderate speed, particularly when
steering.
11. Always try to go straight up or straight down a
slope, never at an angle.
12. Proceed with extreme caution when driving with
wheels close to the edge of a ditch or bank.
13. Never ride on a tractor unless seated on a

304G2 SERIES TRACTOR OPERATION MANUAL
8
Knegt approved seat with seat belt.
14. When driving on public roads, be sure to respect traffic rules and regulations.
15. Do not rest your feet on the brake and the clutch pedals.
16. When driving on roads latch the brake pedals together by using the latch plate,
braking with the pedals unlatched may cause side skidding of the tractor. Try to
avoid overworking the brakes.
1.1.4Towi nglo a ds 
1. To assure tractor stability while working, correctly adjust the towing attachments
(depending on the towed trailer or drawn implement).
2. Be careful when towing and stopping heavy loads.Stopping distance increase with
speed and weight of towed loads, and on slopes.Towed loads with or without
brakes that are too heavy for the tractors or are towed too fast can cause loss of
control.
3. For your personal safety, trailers should not be
towed unless equipped with an independent braking
system.
4. Always use drawbar and towing equipment to pull
heavy loads. Never hook or connect towed
equipment to the 3-point hitch lower links or to the
top link because pitching danger exists.
5. When towing never attempt to make a turn with a locked differential, because you
may not be able to steer the tractor.
1.1.5UsingAgriculturalImplementsand
Machines
1. Do not connect implements or machinery
requiring a higher power rating than your tractor
class.
2. Do not negotiate sharp turns with the PTO under heavy load; this will avoid
damaging the universal joints of the PTO (power take-off) propeller shaft.
3. When connecting the implement to the tractor never stand between the two, while

304G2 SERIES TRACTOR OPERATION MANUAL
9
the tractor is being backed up.
4. Never activate the power take-off (PTO) when it is connected to a moving
implement, without previously making sure that no one is within operating range of
this implement.
5. You can be injured if you use faulty lifting equipment. Make sure that lifting
equipment is in good condition. Make sure that lifting tackle complies with all local
regulations and is suitable for the job. Make sure that lifting equipment is strong
enough for the job. Raised equipment can fall and injure you. Do not walk or work
under raised equipment unless safely supported.
6. No standing on the 3-point hitch or the shield. It
may cause accident.
1.1.6Parkingandle avi ng thetractor
1. Before dismounting, disengage PTO, move
transmission control lever to neutral, stop engine,
lower implements or attachments to ground and
securely engage the park brake. In addition, if
the tractor is left unattended, remove key.
2. When parking look for level grounds if any, shift
into gear and lock the park brake. On sloping
grounds in addition to locking the park brake,
shift into first forward gear if uphill or into first
reverse gear if downhill. For greater safety also use the specific stopping wedge
(available on request); be sure to do so if parking your tractor with a trailer.
1.1.7TractorMaintenance
1. Allow engine to cool off sufficiently before
removing the radiator cap. With the engine
shut-off, slowly turn the cap and release pressure
before removing it completely.
2. Disconnect the storage battery ground cable before
starting to work on any of the electrical system’s

304G2 SERIES TRACTOR OPERATION MANUAL
10
parts or components.
3. Before disconnecting any hydraulic line or hose, make sure the system is
pressure-free.
4. Hydraulic oil escaping under pressure can cause serious personal injury. When
searching for or detecting oil leaks, make sure to use adequate safety protection
such as shields, goggles and gloves.
5. Prior to inspection, cleaning, adjustment or maintenance of the tractor or any
mounted or connected implement, always make sure that engine is shut off. Also
make sure the transmission is in neutral, the brakes
are locked, the power take-off (PTO) is disengaged
and all other moving parts are stationary.
6. Do not fill fuel tank completely when expecting to
work in full sunlight because the fuel might expand
and escape. In such case, promptly wipe off
any fuel that has escaped.
7. Tractor fuel may be dangerous. Never refuel
while engine is running, is still hot, or you are
near an open flame or when someone is
smoking.
8. Do not service the tractor while it is in motion or while the engine is running．When
servicing front-wheel-drive-equipped tractor with rear wheels supported off ground
and rotating wheels by engine power，always
support front wheels in a similar
manner．Engaging front-wheel drive will pull rear
wheels off support if front wheels are not
raised．Tighten wheel hardware to correct torque
as specified in Wheels ，Tires and Tread
section．Torque at intervals shown in Break-In
Period and Lubrication and Maintenance sections，to ensure that wheel hardware
does not loosen．Reinstall protective covers removed during service．
9. Do not work on tires unless suitable tools are available and you have the training

304G2 SERIES TRACTOR OPERATION MANUAL
11
and experience for tire repair. Any incorrect tire installation may seriously threaten
your personal safety. If any doubt exists, have work done by qualified persons.
Explosive separation of a tire and rim parts can
cause serious injury or death.
Always maintain the correct tire pressure．Do not
inflate the tires above the recommended pressure.
Never weld or heat a wheel and tire assembly.
The heat can cause an increase in air pressure
resulting in a tire explosion.
Welding can structurally weaken or deform the
wheel.
When inflating tires, use a clip—on chuck and extension hose long enough to allow
you to stand to one side and NOT in front of or over the tire assembly. Use a safety
cage if available.
Check wheels for low pressure, cuts，bubbles, damaged rims or missing lug bolts
and nuts.
10. Improperly disposing of waste can threaten the
environment and ecology. Potentially harmful
waste used with equipment include such items as
oil, fuel, coolant, brake fluid, filters, and
batteries.
Use leak proof containers when draining fluids.
Do not use food or beverage containers that may
mislead someone into drinking from them.
Do not pour waste onto the ground，down a drain，or into any water source.
Air conditioning refrigerants escaping into the air can damage the Earth's
atmosphere. Government regulations may require a certified air conditioning
service center to recover and recycle used air conditioning refrigerants.
Inquire on the proper way to recycle or dispose of waste from your local
environmental or recycling center,or from your East Wind dealer.
