Tips:

It is best to trim off any side twigs from the main branch being
chipped (Figure 33).

Green branches process quicker and easier than dry branches and
soft wood is easier than hardwood.

Use caution with small diameter green saplings and branches. Chip
these grouped or bundled together to provide support for each other.

Make sure the Chipper finishes chipping material in the Hopper
before shutting the engine off.
Dumping
1. Move the Lanyard off the Outlet Hose Cuff and down onto the Outlet Duct
(Figure 34).
2. Disconnect the Outlet Hose from the Outlet Duct by loosening the
Thumbscrew Clamp and pulling the Hose away.
3. Remove the Back Panel of the Collector by unscrewing the two Knobs until
loose (the Knobs remain attached to the Back Panel)(Figure 35). Pull back
on the two Back Panel Handles to separate the bottom of the Back Panel and
pull down to remove the Back Panel from the Collector.
1. While holding down on the Dump Handle, pull the Dump Lever (Figure 36)
to unlock the Collector Base and then raise the Collector Base using the
Dump Handle to dump the Collector.


Always shut off the tractor engine and the vacuum engine and use caution
when dumping the collector box load.
 The load may have shifted against the rear panel. Push down on the
dump handle when releasing the dump lever to prevent the Collector Base
from suddenly tipping.

Never back up with the trailer in the dump position.
