li
tractor fuel. Vaporized diesel fuel is as
dangerous as gasoline. Do not overfill.
SAFE OPERATION IN ROUGH TERRAIN
1. Drive tractor slowly on hillsides and
curves to eliminate the danger of tipping.
Avoid slopes which are too steep for safe
operation.
5. Do not smoke and avoid open flames when
filling batteries.
6. Ether Starting fluid is highly flammable. Do
not use near fire, sparks, open flames or while
engine is running.
2. Always drive slowly over rough ground. Drive
at speeds slow enough to ensure your safety.
7. Remove mud, crop residue, chains and tools
from steps and operator's platform. They may
interfere with pedal operation or entry/exit
from tractor.
3. Avoid sharp turns on hillsides.
4. When driving out of a ditch, gully or up
t steep hillside, engage the clutch slowly.
8. Turn lever OFF at hydraulic couplers to pre-
vent flow to implements when servicing.
5. When descending steep grades, select a
sufficiently low gear to maintain control with
minimum braking.
9. Ground fuel storage tanks to prevent static
buildup.
1 . Ensure turbocharger is cool before
servicing. 11. Keep flammable material away from
tur- bocharger.
6. Never drive near the edge of a ditch or gully
unless absolutely necessary.
7. Be especially alert when operating tractor at
row ends, road slopes and around bStUC
12. Never mount a damaged tire. Tire may ex-
plode.
tions. MAINTENANCE SAFETY
1. Escaping hydraulic oil under pressure can
penetrate the skin caus- ing personal injury.
En- sure connections are tight and lines and
hoses are un d amaged. Before disconnecting
hydraulic lines, relieve all pressure. Do not
overfill tank.
IMPLEMENT SAFETY
1. Always hitch loads to drawbar or hitch
points.
2. When hitching drawn equipment to drawbar,
back tractor past clevis then move forward so
that in making the connection, tractor is moving
away from equipment.

Safety
11
3. Always lower implements to the ground when
not in use and turn OFF lever couplers. Hydraulic
pressure can rupture hoses, releasing high
pressure oil causing imple- ment damage.
CHEMICAL SAFETY
1. The cab air filters are not designed to
filter harmful chemicals. When using agricultural
chemicals, follow the manufacturer's in-
structions carefully.
4. Be careful when turning with a towed imple-
ment. Lift it from the ground during turns. Side
thrust could damage tires or im- plements.
2. Do not carry harmful chemicals in the
cab. Chemicals may rupture the container and
the fumes may poi9on the operator.
5. Use transport locks, lower implement to
ground and securely block frame before ser-
vicing implement.
3. Wear OSHA approved respiratory protection when
working near toxic chemicals. Main- tain
equipment regularly.
SAFE HIGHWAY OPERATION
1. Equip towed implements with slow moving
vehicle (SMV) signs when travell- ing on public
roads.
ARTICULATION LOCK
1. Use articulation lock during stationary ap-
plications, servicing, jacking or overhaul
operations. Do not use when tractor is mov- ing.
2. Install additional lights on implement rear
to safeguard against rear end collisions.
Daybreak and dusk are particularly dangerous.
VERSATILE tractors have seven pin connectors to
facilitate installation of ex- tra lighting.
2. Before engaging lock, drive tractor to a
level surface, put steering straight, engage
parkbrake, put gearshift in neutral and stop
engine. Remove pin from storage position and put
through hole on rear of front frame. Insert pin
and secure with klik pin. It may be necessary to
start engine and articulate frame sllghtly to
ensure lockpin is through.
3. Be aware of transport width of towed im-
plements. Install additional lights to left side
of wide implements to alert passing traffic. Keep
clear of the approaching lane.

1. Use hazard warning flashers when transpor- ting
   or driving tractor on public roads unless
   prohibited by law in your area. Check with
   local authorities.
2. Keep to the right and yield the right-of-way
   especially when pulling implements. Pull off
   road and stop to allow motorists to pass. Drive
   on road shoulder, if permitted by law.
3. Use extreme caution when pulling heavy loads at
   road speeds. Avoid hard application of tractor
   brakes at high speeds.

7. Ensure headlights are adjusted so they will
not blind operators of oncoming vehicles.
