Wipe the battery top and coat the terminals with liquid par-

WARNING: Batteries generate explosive
gases. Sparks, flames, lit cigarettes or any
flammable source must be kept away. Wear
appropriate safety goggles when working
near batteries.

Check the fan and alternator belts tension every 400 hours.
Retighten the nuts.
Get your dealer or agent to check the alternator every
1,200 hours or once a year.
IMPORTANT: The alternator wiring must be discon-
nected before any arc welding is carried out on the trac-
tor or on an implement which is attached to it. Do not
disconnect or reconnect the battery cables when the
engine is running. Never operate the engine when the
cable linking the alternator and battery is disconnected.
Do not attempt to connect any additional electrical
