SECTION 00 - - GENERAL GUIDELINES - - CHAPTER 1
START UP
--
Never start the engine in confined spaces that
are not equipped with adequate ventilation for
exhaust gas extraction.
--
Never bring your head, body, arms, legs, feet,
hands, fingers near fans or rotating belts.
ENGINE
--
Always loosen the radiator cap slowly before re-
moving it to allow any remaining pressure in the
system to be discharged. Coolant should only be
added when the engine is stopped or idling, if hot.
--
Never fill up with fuel when the engine is running,
especially if hot, in order to prevent the outbreak
of fire as a result of fuel spillage.
--
Never check or adjust fan belt tension when the
engine is running.
Never adjust the fuel injection pump when the ve-
hicle is moving.
--
Never lubricate the vehicle when the engine is
running.
ELECTRICAL SYSTEMS
--
If it is necessary to use auxiliary batteries, re-
member that both ends of the cables must be
connected as follows: (+) with (+) and (--) with (--).
--
Avoid short--circuiting the terminals. GAS RE-
LEASED FROM BATTERIES IS HIGHLY IN-
FLAMMABLE.
--
During charging, leave the battery compartment
uncovered to improve ventilation.
--
Never check the battery charge using "jumpers"
(metal objects placed on the terminals).
--
Avoid sparks or flames near the battery zone to
prevent explosion hazards.
--
Before servicing operations, check for fuel or cur-
rent leaks. Eliminate any eventual leaks before
starting work.
--
Never charge batteries in confined spaces. Make
sure that there is adequate ventilation in order to
prevent accidental explosion hazards as a result
of the accumulation of gases released during
charging operations.
--
Always disconnect the battery before performing
any kind of servicing on the electrical system.
HYDRAULIC SYSTEMS
--
A liquid leaking from a tiny hole may be almost in-
visible but, at the same time, be powerful enough
to penetrate the skin. Check for leaks using a
piece of cardboard, NEVER USE HANDS.
--
If any liquid penetrates skin tissue, call for medi-
cal aid immediately.
--
Serious skin infections may result if medical
attention is not given.
--
Use the specific tools when checking pressure
values on the hydraulic system.
WHEELS AND TIRES
--
Check that the tires are correctly inflated at the
pressure specified by the manufacturer.
Periodically check possible damages to the rims
and tires.
--
Stand away from (at the side of) the tire when
checking inflation pressure.
--
Only check pressure when the tractor is un-
loaded and the tires are cold, to avoid incorrect
readings as a result of over--pressure.
--
Do not re--use parts of recovered wheels as in-
correct welding or brazing may heat the material,
causing it to weaken and eventually damage or
break the wheel.
--
Never cut or weld a rim mounted with an inflated
tire.
--
When removing the wheels, lock both the front
and rear vehicle wheels.
--
Always position support stands when raising the
vehicle, in order to conform to current safety re-
gulations.
--
Deflate the tire before removing any object
caught in the tire tread.
--
Never inflate tires using inflammable gases; this
could cause an explosion and put operator safety
at risk.
REMOVAL AND INSTALLATION
--
Lift and handle all heavy parts using suitable lift-
ing equipment and make sure that all slings and
hooks are correctly secured.
--
Handle all parts carefully during lifting oper-
ations, keep an eye on the personnel working
near the load to be lifted. Never insert hands or
fingers between parts, always wear approved
accident prevention clothing (goggles, gloves
and work boots).
--
Avoid twisting chains or metal cables and always
wear safety gloves when handling cables or
chains.
