rial into the feeder. Do not reach into the hopper past the
curtain barrier.
a.Before beginning to feed the rotor is up to speed.
b.Slowly slide the wooden material into the feed hopper
and move it into the rotor.d
c.Do not force the material into the rotor, as the material
engages the rotor, the rotor will draw the material in. Use
continuous lite pressure to guide in the material.
d.Be aware of how much material you feed in, slow down
or stop if the rotor begins to slow down.
e.Do not reach into the feed hopper further than the
curtain to be sure not to contact the blades on the rotor.
f.Use a stick or branch to push any piece of material into
the rotor that does not move on its own. If the jam
persists then stop the engine and wait for the rotor to
stop and then clear the jam. Do not take a chance with
getting your hand caught in the rotor.
g.Ensure your wood chip pile is contained and doesn't
affect the immediate work area.

MAINTENANCE
By following a careful service and maintenance program
for your machine, you will enjoy many years of trouble free
operation.
The rotor and ledger blades need to be sharp for the
Chipper to perform as expected. Periodic inspection is
recommended. Keep the blades sharp to reduce the
amount of power required during operation. Watch the
sharpness of the blades when processing material with a
lot of sand, soil or dirt mixed with it. Reverse or sharpen
the blades if the cutting edge becomes dull. Twig breaker
should be inspected for gouges or bent.
The rotor is equipped with 4 blades spaced evenly to keep
the rotor in balance. If one needs to be changed, the one
opposite should also be changed.
It is recommended that the rotor blades be removed from
the rotor when sharpening. Always sharpen the blades at
a 45° angle to provide the best cutting effect as it meets
the stationary blade. Be sure to tighten the blade mount-
ing bolts to their specified torque when reinstalling the
blades to the rotor.
1.Turn off the hydraulics, stop the engine, remove the
ignition key, and place it in your pocket and wait for all
moving parts to stop.
2.Remove the bolt that secures the upper rotor housing,
and carefully open the rotor housing.
3.Manually rotate chipper rotor plate so that the blade is
fully exposed
4.Remove the bolts that hold the rotor blade to the rotor,
remove the blade.
5.Rotate the blade and reinstall or replace with new or
resharpened blade.
6.Ensure the blade is properly oriented, with the leading
edge out.The blade is designed to fit into the rotor one
way only. See diagram for proper installation.
7.Tighten down bolts as specified in the torque chart.
8.Repeat steps for remaining blades.

blade. It is recommended that the clearance between the
rotor and stationary blades be set and maintained at
1/32 to 1/16 " (.76 - 1.52 mm) to obtain the best perfor-
mance.
1. Turn off the hydraulics, stop the engine, remove the
ignition key and place it in your pocket and wait for all
moving parts to stop.
2. Remove the 2 bolts that hold the ledger blade to the
ledger mount, remove the blade.
3. Rotate the blade and replace or replace with new or
re-sharpened blade.
4. Hand tighten the bolts and set the clearance
between the ledger and rotor blades at 1/32 - 1/16" .
5. Tighten down bolts as specified in the torque chart .
CHECKING BOLT TORQUE
The tables shown below give correct torque values for
various bolts and cap screws. Tighten all bolts to the
torques specified in chart unless otherwise noted. Check
tightness of bolts periodically, using bolt torque chart as
a guide. Replace hardware with the same strength bolt.
Torque figures indicated above are valid for non-greased
or non-oiled threads and heads unless otherwise speci-
fied. Therefore, do not grease or oil bolts or cap screws
unless otherwise specified in this manual. When using
locking elements, increase torque values by 5%.
* Torque value for bolts and cap screws are identified by
their head markings
