OPERATION
Feeding Material
The flow control valve (Figure 5) will control the speed of the material being fed into the chipper,
The tractor’s hydraulic pressure will also contribute to the speed of the feed.
To adjust the speed of the feed system, find a small branch and feed it into the chipper with the
feed adjusted to 3 or 4 and keep adjusting up until the chips are 3/8 to 1/2 inch (9-12mm) thick.
The feed setting “0” will completely stop the flow of oil to the drive motors, stopping the feed roller.
The hydraulic system on the chipper requires at least 8 GPM to operate the chipper at full capacity.
Sometimes when the brush is wet or if there is a lot of small twigs and branches the feed roller can
slip because of the wet wood or the small size material. In this situation it is best to grab the control
bar and switch it from forward to reverse several times. You can even reverse the material and turn
it a different way so that the roller grabs a different part of the branch.
Shown above (Figure 6) is the control bar that operates the feed roller. This control bar has three
positions, forward, neutral, and reverse. The feeding position is to the rear of the machine so that
in an emergency the operator can just push the control bar and it will either stop or reverse the
feed roller. Always keep the control bar in the neutral position whenever you are not feeding the
chipper to eliminate the chance of accidently feeding something into the machine
