FEED WHEEL TENSION SPRINGS

• The upper feed wheel has two tension

springs. These springs should only be

tight enough to keep the feed wheel teeth

from slipping on the material. DO NOT

OVER TIGHTEN! If the springs are

overly tight, it will over work the

hydraulic system and make it difficult to

feed large material. The springs can be

adjusted using the nuts on the bolt at the

bottom of the spring.

HITCH

• Make sure the bolts on the chipper hitch

are tightened. If not, tighten to the

specified torque for the bolts size. Also,

make sure the hitch bolts on the tow

vehicle are tightened properly.

• Check the bolts and nuts for wear. If

bolt or nut threads are chipped or worn

down, or if the bolts and nuts won’t stay

tight after tightening them, the bolts and

nuts need to be replaced. Check the bolt

holes for wear also. If the holes are

stretched or distorted, the hitch will need

to be replaced.

• Keep the Pintle ring on the chipper

greased. This will keep the wear

between the two metal surfaces down to

a minimum and will make your hitch last

longer.

• If the Pintle ring is worn and does not fit

the hitch on the tow vehicle properly,

replace it as soon as possible. The loose

fit between the two surfaces may cause

the chipper to swerve in traffic and

possibly even come uncoupled from the

tow vehicle. Also check the hitch on the

tow vehicle for wear for the same

reasons.
