SECTION V MAINTENANCE
Condenser fins must always be duly clean. Cleaning should be done using
water or an air jet (pay particular attention not to bend the fins, if necessary
straighten the fins again using a special tool).
Ascertain that the compressor is firmly secured to tractor and the pulleys
are properly aligned.

necessary to plug the inlet and oulet pipes at once, this to prevent both
dust and moisture from entering the system.
