Dumping - Manually
NOTE: For safety reasons, the DR POWERWAGON-PRO Bed
is designed NOT to dump automatically once you
release the Dump Lever. You must pull the Dump
Handle back then lift the back of the Bed to cause it to
tip forward.
1. Remove the Front Panel.
2. Stand at the rear of the Bed.
3. Pull the Handle on the Dump Lever (Figure 9), and
then pull up on the rear of the Bed to dump the
load (Figure 10).
4. After unloading, push the Bed back down into
place by hand. Be sure the Dump Lever latches
securely.
NOTE: The Bed of the DR POWERWAGON-PRO is balanced
so you can dump the load with minimal effort. If you are
carrying a very heavy load, you may not be able to lift the
Bed to dump it when you release the Latch Lever. In this
case, you will need to manually remove part of the load
from the back of the Bed, until the load is light enough to
allow the Bed to tip forward when you lift up on the back
of it.
