Safe Maintenance; Storage, Handling And Cleaning - Valtra A800R Operator's Manual

1. Safety

1.2.5 Safe maintenance

• Do not perform any repair or maintenance
service with the engine running or still hot, or
with the tractor in motion.
• Before making adjustments or repairing the
electrical system, disconnect the battery
cables: The negative (-) cable first.
• To prevent fires or explosions, keep open
flames away from the battery or cold start aid
devices. To prevent sparks, which can cause
explosions, use bridge cables in accordance
with the instructions provided in this manual.
• When performing repairs or adjustments, it is
recommended that you consult a Valtra dealer
so the work may be carried out by trained
personnel.
• The implement and/or tractor must be placed on wooden blocks or suitable stands, never on a hydraulic
jack.
• Periodically check the tightness of all nuts and bolts, especially wheel hub and rim nuts. Tighten to the
recommended torques.

1.2.6 Storage, handling and cleaning

The purity and cleanliness of fuel are vital to the
proper operation of the engine and the durability of
the injection system. Therefore, to ensure that
your fuel meets the requirements, follow the
recommendations below:
• Use reservoirs equipped with two taps, one on
each end. Plastic tanks are preferable. In the
case of metallic tanks, use stainless steel tanks
or tanks with an appropriate inside coating—not
zinc—because it contaminates the fuel,
affecting the life of the injection systems and
engine.
• Never use galvanized tubes, registers, tanks or
vessels because the coating reacts with the
diesel, forming residues.
• The drum or reservoir in use must be protected
from the sun, rain and dust. It must also be
supported on stands and in a horizontal
position, at a slight angle, so that the discharge
side is around 10 cm higher than the other side.
Thus, any water and impurities will be
deposited at the bottom, being discharged by
the tap on the opposite end.
• The reservoirs must have a waterproof vent
located at the higher end.
