When carrying out controls, adjustments or analyses for troubleshooting, park the machine on firm, level
ground. Apply all the machine safety devices and use blocks to prevent any machine movement.
When more than one person is engaged in the work, use the prescribed notices that indicate that the machine
is undergoing maintenance. Do not allow any unauthorised persons to remain in the vicinity.
When checking the level of the cooling liquid, wait until this liquid has cooled. If the radiator cap is removed
while the liquid is still hot and under pressure, it may cause severe burns.
Take great care not to get entangled in moving parts (fan, alternator belt or any of the rotating elements).
