General Considerations - New Holland TV145 Repair Manual

GENERAL CONSIDERATIONS

Solvents
Use cleaning fluids and solvents that are known to be
safe. Certain types of fluids can cause damage to
components, such as seals, and can cause skin
irritation. Solvents should be checked that they are
suitable not only for the cleaning of components and
individual parts, but also that they do not affect the
personal safety of the user.
Housekeeping
Many injuries result from tripping over or slipping on
objects or material left lying around by a careless
worker. Prevent these accidents from occurring. If
you notice a hazard, don't ignore it remove it.
A clean, hazard-free place of work improves the
surroundings and daily environment for everybody.
Fire
Fire has no respect for persons or property. The
destruction that a fire can cause is not always fully
realized. Everyone must be constantly on guard.
Extinguish matches, cigars, and cigarettes before
throwing them away.
Work cleanly, disposing of waste material into proper
containers.
Locate the fire extinguishers and find out how to
operate them.
Do not panic - warn those near and raise the alarm.
Do not allow or use an open flame near the tractor
fuel tank, battery, or component parts.
First Aid
In the type of work that mechanics are engaged in,
dirt, grease, and fine dusts settle upon the skin and
clothing. If a cut, abrasion or burn is disregarded it
may become infected within a short time. Seek
medical aid immediately.
Cleanliness
Cleanliness of the tractor hydraulic system is
essential for optimum performance. When carrying
out service and repairs, plug all hose ends and
component connections to prevent dirt entry.
Clean the exterior of all components before carrying
out any form of repair. Dirt and abrasive dust can
reduce the efficiency and working life of a component
and lead to costly replacement. Use of a
high-pressure washer or steam cleaner is recom-
mended.

OPERATIONAL CONSIDERATIONS
Stop the engine, if at all possible, before performing
any service.
Place a warning sign on tractors which, due to service
or overhaul, would be dangerous to start. Disconnect
the battery leads if leaving such a unit unattended.
Do not attempt to start the engine while standing
beside the tractor or attempt to bypass the safety
start switch.
Avoid prolonged running of the engine in a closed
building or in an area with inadequate ventilation as
exhaust fumes are highly toxic.
Always turn the radiator cap to the first stop to allow
pressure in the system to dissipate when the coolant
is hot.
Never work beneath a tractor which is on soft ground.
Always take the unit to an area which has a hard
working surface, preferably concrete.
If it is found necessary to raise the tractor for ease of
servicing or repair, make sure that safe and stable
supports are installed beneath axle housings,
casings, etc., before starting work.
Certain repair or overhaul procedures may necessi-
tate separating the tractor, either at the engine/trans-
mission or transmission/rear axle location. These
operations are simplified by the use of the Tractor
Splitting Stands. Should this equipment not be
available, every consideration must be given to
stability, balance and weight of the components,
especially if a cab is installed.
Use footsteps or working platforms when servicing
those areas of a tractor that are not within easy reach.
Before loosening any hoses or tubes connecting
implements to remote control valves, etc., switch off
the engine, remove all pressure in the lines by
operating levers several times. This will remove the
danger of personal injury by oil pressure.
Prior to pressure testing, make sure all hoses and
connectors of the tractor and the test equipment are
in good condition and tightly sealed. Pressure
readings must be taken with the gauges specified.
The correct procedure should be rigidly observed to
prevent damage to the system or the equipment, and
to eliminate the possibility of personal injury.
WARNING
Escaping hydraulic/diesel fluid under pressure
can penetrate the skin causing serious injury.
