16 6 INCH CHIPPER
OPERATION
4.7 smarT relaY
the bear Cat chipper is equipped with a Smart Relay
hydraulic feed control that is located beneath the control
panel. It monitors the chipper rotor RPM and helps to
regulate the feed roller.
When chipper rPm drops below the preset range the
feed roller is stopped automatically to help the chipper
process backed up materials. the screen will read
"Forward Feed Stopped."
When the rPms are back up to an acceptable level the
feed roller will automatically reengage. the screen will
read "Forward Feed available."
for s & f models only, if the safety bar has been ac-
tivated, the feed roller will stop automatically and the
screen will read "Forward Feed Stopped." Push the
reset/override button to resume forward feed.
When the hydraulic pressure is too high, (if the feed
roller becomes obstructed) the controller will reverse the
feed roller momentarily to try to remove the material that
wasn't chipped. the screen will read "try again feature
activated." the controller will then engage the roller into
the forward position and try to feed the material again.
if this cycle continues, the obstruction will have to be
removed manually, or material to be chipped should
be removed, trimmed, and/or repositioned.
Your smart relay comes preprogrammed at the fac-
tory. If it should malfunction and the screen reads "No
Program available," contact your dealer immediately.
the Smart Relay will not allow the chipper to operate
until it has been properly programmed.
4.6 removing Jammed maTerials
The feed roller lift jack is used to raise the feed roller if
chipping material becomes wedged in or behind the feed
roller. Raise the feed roller to safely remove the material.
To release Jammed maTerials:
turn the machine off and allow all moving parts to come
to a complete stop.
Remove the retaining pin from storage position (see
figure below).
Turn check valve clockwise to engage the jack pump.
Once the jack is engaged, pump the handle to raise
the feed roller until the lock pin position aligns with one
of the support bracket holes.
Secure the position by putting the lock pin through the
support bracket and lock pin position.
Clear materials out from underneath the feed roller.
Remove the lock pin.
turn the check valve counterclockwise to disengage
the pump and lower the jack.
Replace retaining pin in storage position.

Select limbs that are up to 6 inches in diameter.
trim side branches that cannot be bent enough to
feed into the chipper chute.
Small diameter branches can be held together in a
bundle and fed in simultaneously.
the actual feed rate of the limb into the chipper will
depend on the type of material fed, and sharpness of
the cutting blades.

noTe
The RPM sensor on the rotor must be flashing or the
controller won’t work. Clearance between the sensor
and the bolt must be between 1/32” and 3/32”. there
are also two sensors in the feed roller control box. these
sensors must have a clearance of 5/64" (2mm).
