INTRODUCTION
Before removing hydraulic accumulators for servicing, the liquid pressure in the accumulators must be reduced to
zero.
Pressure check on hydraulic accumulators shall be carried out by method recommended by the accumulator manu-
facturer.
Care must be taken not to exceed the maximum allowable pressure of the accumulator. After any check or adjustment
there must be no leakage of gas.
Safety rules
A careful operator is the best operator. Most accidents
can be avoided by observing certain precautions.
To
help prevent accidents, read and take the following
precautions before operating this tractor.
Equipment
should be operated only by those who are responsible
and instructed to do so.
The tractor
1. Read the Operator's Manual carefully before using the tractor. Lack of operating knowledge can lead to accidents.
2. Use an approved roll bar and seat belt for safe operation. Overturning a tractor without a roll bar can result in
death or injury. If your tractor is not equipped with a roll bar and seat belt, see your NEW HOLLAND Dealer.
3. Always use the seat belt. The only instance when the seat belt should not be used is if the roll bar has been
removed from the tractor or folding ROPS is in down position.
4. If a front end loader is to be installed, always use a FOPS (Falling Object Protective Structure) canopy to avoid
injury from falling objects.
5. Use the handrails and step plates when getting on and off the tractor to prevent falls. Keep steps and platform
cleared of mud and debris.
6. Do not permit anyone but the operator to ride on the tractor. There is no safe place for extra riders.
7. Keep all safety decals clean of dirt and grime, and replace all missing, illegible, or damaged safety decals. See
the list of decals in the Decal section of this manual.
Servicing the tractor
1. The cooling system operates under pressure which is controlled by the radiator cap. It is dangerous to remove
the cap while the system is hot. Always turn the cap slowly to the first stop and allow pressure to escape before
removing the cap entirely.
2. Keep any type of open flame away from the tractor and do not smoke while refuelling. Wait for the engine to cool
before refueling.
3. Keep the tractor and equipment, particularly brakes and steering, maintained in a reliable and satisfactory con-
dition to ensure your safety and comply with legal requirements.
4. Keep open flame or cold weather starting aids away from the battery to prevent fires or explosions. Use jumper
cables according to instructions to prevent sparks which could cause explosion.
5. Stop the engine before performing any service on the tractor.
6. Escaping hydraulic/diesel fluid under pressure can penetrate the skin causing serious injury. If fluid is injected
into the skin, obtain medical attention immediately or gangrene may result.
• Do not use your hand to check for leaks.
• Use a piece of cardboard or paper to search for leaks.
• Stop the engine and relieve pressure before connecting or disconnecting lines.
• Tighten all connections before starting the engine or pressurizing lines.
7. Do not modify or permit anyone else to modify or alter this tractor or any of its components or functions without
first consulting a NEW HOLLAND Dealer.
8. The fuel oil in the injection system is under high pressure and can penetrate the skin. Unqualified persons should
not remove or attempt to adjust a pump, injector, nozzle, or any other part of the fuel injection system. Failure to
follow these instructions can result in serious injury.
9. Continuous long-term contact with used engine oil may cause skin cancer. Avoid prolonged contact with used
engine oil. Wash skin promptly with soap and water.
