Checking the engine vibration damper
Contact an authorised Valtra workshop for checking of the engine vibration damper.
The outer circumference of the vibration damper (belt pulley) can twist in relation
to the hub. For this reason, alignment marks have been added to the damper
front face, which indicate the possible twisting.

Maintaining the air conditioning
Maintain the air conditioning regularly.
IMPORTANT: If the air conditioning system has not been used for a while, free
the compressor before starting the engine by rotating the pulley nut with a
wrench.
CAUTION: Do not attempt to remove any part of the air conditioning
system.
NOTE: Make sure that the compressor starts. At low temperatures, the
thermostat prevents the compressor from starting.
