CAUTION: Always set the gear selector to neutral position.
Move the arms up to the maximum height with the hydraulic hatch closed.
CAUTION: If someone on the ground assists you during unloading, be extremely careful in carrying
out the manoeuvres and keep eye contact at all times.
CAUTION: Avoid sudden inversion of drum rotation when the drum is full or partially full and raised on
uneven, bumpy or soft ground.
CAUTION: When working on side slopes do not rotate the rotary frame with the unloading chute facing
downhill. Avoid steep slopes when you need to traverse with the rotary frame.
Keep the arms at the maximum height.
CAUTION: Carefully rotate the drum to prevent unbalancing the wheels.
CAUTION: The use of drum side unloading is only permitted with the machine stationary and placed
on compact ground, with slopes not exceeding 5%.
