UNLOADING

1. Load and unload on firm level ground only. Maintain a safe distance from the edge of a road.
2. Apply the brakes on the trailer securely and insert blocks
under the tires to ensure that the trailer does not move.
Then fix the ramps in line with the centers of the trailer and
the machine.
Be sure that the two sides are at the same height as one
another.
Make the angle of the ramps a maximum of 15º.
Set the distance between the ramps to match the center of
the tires.
If the ramp sags appreciably, reinforce it with blocks, etc.
3. Remove the chains and wire ropes fastening the machine.
4. Start the engine.
Warm the engine up fully.
