Trailer brakes typically are not automatically engaged

when the tractor transmission is in Park, and may not be

engaged by any tractor Emergency Brake.

Both brake systems include four chock blocks to be man-

ually installed for parking the 8315-8324DVN. The tractor

cannot set the implement wheel chocks.

Braking Hazards:

Make sure the operator understands when Discovator brakes

are engaged and when they are released (make a record of

tractor behaviour on page 33).

Also understand and comply with tractor operational restric-

tions when trailer brakes are used. For example, it is generally

necessary to inter-tie split brakes, and avoid differential (steer-

ing braking) if trailer brakes are used.
