12” CHIPPER MACHINE CONTROLS

VARIABLE SPEED CONTROL

• The variable speed control valve

controls the speed of the feed wheels.

Turn the valve clockwise to make the

feed wheels turn faster. Loosen the lock

washer on the end of the control knob

and adjust the wheels to the desired

speed and then retighten the washer.

LIFT CYLINDER CONTROL VALVE

(OPTIONAL EQUIPMENT)

• The Carlton chipper may be equipped

with a hydraulic yoke lift, which allows

the operator to hydraulically lift the top

feed wheel. This can be of assistance

when feeding large square cut butt ends,

which the feed wheels cannot ride up

easily. The lift cylinders can also be

used to provide positive down pressure

on material being fed. This is useful

when feeding extremely bushy material

or material which the feed wheel cannot

grab.

• The Lift cylinder control valve is located

on the right rear of the infeed chute.

− Push the valve in to raise the lift

cylinder and top feed wheel

− Pull the valve handle out to lower the

lift cylinder and provide positive

down pressure on the top feed wheel.
