5.4 Feed Roller Flow Control Valve
The hydraulic feed circuit is equipped a flow control valve that
can be manually set to adjust chipping speed rate.
The flow control valve sets the speed of the feed rollers. Use the
material size and the quality of the job required to establish the
appropriate feed speed.
•
Increase the speed when chipping brush or twigs.
•
Decrease the speed when chipping hard, solid material or
when the engine load is excessive.
The operator can adjust the feeding speed appropriate for the
operating conditions.
A scale on the face of the valve is numbered from 0–10
(0–100%).
If the hydraulic oil flow from the tractor exceeds the
requirements of the chipper, adjust the flow control valve.
To adjust the feed rate:
1.
Loosen the thumb screw (2).
2.
Move the control lever (1) to the desired position.
3.
Tighten the thumb screw.

5.5 Easy Start System
Easy Start
means there is 1/2"–1" (12–25 mm) free movement
at the top of the feed roller springs allowing the roller wheel to
easily climb up on large material before spring tension begins.
Spring tension keeps the upper roller pressing down on the
material as it is fed through the chipper.
Spring tension can be adjusted in the following manner:
IMPORTANT! Adjust feed roller tensioners the same
amount on both sides. Measure exposed bolt threads and
adjust so they are equal length.
1.
Hold the upper nut and turn the bottom nut counter-
clockwise to loosen.
2.
Adjust the top nut—
-
clockwise to
increase
tension or
-
counterclockwise to
decrease
tension
3.
Hold the top nut and tighten the bottom jam nut.
