Safety rules
LEGAL OBLIGATIONS
This machine may be equipped with special guarding or other devices in compliance with local legislation. Some to
these require active use by the operator. Therefor, check local legislations on the usage of this machine.
ACCIDENT PREVENTION
Most accidents or injuries that occur in workshops are the result of non compliance to simple and fundamental safety
principles. For this reason, IN MOST CASES THESE ACCIDENTS CAN BE AVOIDED by applying the fundamental
safety principles, acting with the necessary caution and care.
Accidents may occur with all types of machine, regardless of how well the machine in question was designed and
built.
CAUTION
Unexpected machine movement!
1. Disengage all drives.
2. Engage parking brake.
3. Lower all attachments to the ground, or
raise and engage all safety locks.
4. Shut off engine.
5. Remove key from key switch.
6. Switch off battery key, if installed.
7. Wait for all machine movement to stop.
Failure to comply could result in minor or
moderate injury.
C0038A
SAFETY REQUIREMENTS FOR FLUID POWER SYSTEMS AND COMPONENTS - HY-
DRAULICS (EUROPEAN STANDARD EN982)
• Flexible hose assemblies must not be constructed from hoses which have been previously used as part of a hose
assembly.
• Do not weld hydraulic pipes: when flexible hoses or piping are damaged, replace them immediately.
• It is forbidden to modify a hydraulic accumulator by machining, welding or any other way.
• Before removing hydraulic accumulators for servicing, the liquid pressure in the accumulators must be reduced to
zero.
• Pressure check on hydraulic accumulators must be carried out by a method recommended by the accumulator
manufacturer.
• Take care not to exceed the maximum allowed pressure of the accumulator. After any check or adjustment, check
for leakages or gas in the hoses or tubes.
SAFETY RULES
General guidelines
• Carefully follow specified repair and maintenance procedures.
• When appropriate, use P.P.E (Personal Protective Equipment)
• Do not wear rings, wristwatches, jewellery, unbuttoned or loose articles of clothing such as: ties, torn clothing,
scarves, open jackets or shirts with open zips that may remain entangled in moving parts. It is advised to wear
approved safety clothing, e.g.: non-slip footwear, gloves, safety goggles, helmets, etc.
• Do not carry out repair operations with someone sitting in the driver's seat, unless the person is a trained technician
who is assisting with the operation in question.
• Do not operate the machine or use any of the implements from different positions, other than the driver's seat.
• Do not carry out operations on the machine with the engine running, unless specifically indicated.

11. INTRODUCTION
• Bring all hydraulic cylinders to the home positions (down, retracted, etc.) before engine shut down.
• Stop the engine and check that the hydraulic circuits are pressure-free before removing caps, covers, valves, etc.
• All repair and maintenance operations must be carried out using extreme care and attention.
• Service steps and platforms used in the workshop or elsewhere should be built according to the applicable stan-
dards and legislation.
• Disconnect the Power Take-Off (PTO) and label the controls to indicate that the machine is being serviced.
• Brakes are inoperative when manually released for repair or maintenance purposes. Use blocks or similar devices
to secure the machine in these conditions.
• Only use specified towing points for towing the machine. Connect parts carefully. Make sure that all pins and/or
locks are secured in position before applying traction. Never remain near the towing bars, cables or chains that are
operating under load.
• When loading or unloading the machine from the trailer (or other means of transport), select a flat area capable of
sustaining the trailer or truck wheels. Firmly secure the machine to the truck or trailer and lock the wheels in the
position used by the carrier.
• Electric heaters, battery-chargers and similar equipment must only be powered by auxiliary power supplies with
efficient ground insulation to avoid electrical shock hazards.
• Always use suitable hoisting or lifting devices when raising or moving heavy parts.
• Keep bystanders away.
• Never use gasoline, diesel oil or other inflammable liquids as cleaning agents. Use non-inflammable, non toxic
commercially available solvents.
• Wear safety goggles with side guards when cleaning parts with compressed air.
• Never use open flames for lighting when working on the machine or checking for leaks.
• When carrying out checks with the engine running, request the assistance of an operator in the driver's seat. The
operator must maintain visual contact with the service technician at all times.
• If operating outside the workshop, position the machine on a flat surface and lock in position. If working on a slope,
lock the machine in position. Move to a flat area as soon as is safely possible.
• Maintenance and repair operations must be carried out in a clean and dry area. Clean up any water or oil spillage
immediately.
• Do not create piles of oil or grease-soaked rags as they represent a serious fire hazard. Always store rags in a
closed metal container.
• Before engaging the machine, make sure that there are no persons within the machine or implement range of action.
• Empty your pockets of all objects that may fall accidentally unobserved into the machine inner compartments.
• When metal parts are sticking out, use protective goggles or goggles with side guards, helmets, special footwear
and gloves.
• When welding, use protective safety devices: tinted safety goggles, helmets, special overalls, gloves and footwear.
All persons present in the area where welding is taking place must wear tinted goggles. NEVER LOOK DIRECTLY
AT THE WELDING ARC WITHOUT SUITABLE EYE PROTECTION.

NOTE: The engine and cooling system used in the combine is designed to be removed as a modular unit. The follow-
ing engine removal procedure demonstrates the removal of the engine only from the module. This procedure takes
into consideration the possible unavailability of proper, or sufficient lifting equipment for complete module removal.
When possible, remove the engine and cooling system module as designed.
