with considerable velocity Keep away
from the area around the discharge chute
Always stop the engine and disconnect
the spark plug wire when renioving or
attaching the bag when changing
containers or when removing the
shredded material ,
If if becomes necessary to push materials into the
chipper-shredder, use a small diameter stick, NOT
YOUR HANDS The stick should be small enough that
it will be ground up if it gets into the impeller assembly.
WARNING
A(
Do not deposit material larger then 12"
diameter in the hopper or upper guide
exterrsion Any materia! heavier then 1/2”
should be fed into the chip-it guide
Leaves and smaller branches can be fed into the
hopper with the leaf ramp raised as shown in figures

into the chipper-shredder at a steady rate it is
possible to feed too fast. Experiment with feeding rates
to determine what rate provides the best results
without stalling the engine or plugging the discharge
chute.
The discharge chute will direct the shredded materia!
into a pile, a container or the bag provided with your
shredder

CARBURETOR ADJUSTMENT
WARNING
If any adjustments are made to the engine while the engine if running {eg- car
buretor), keep clear of al! moving parts
Be careful of heated surfaces and muffler.
Minor carburetor adjustment may be required to com
pensate for differences in fuel, temperature, altitude or
load
NOTE
A DIRTY AIR CLEANER WILL CAUSE
ENGINE TO RUN ROUGH. BE CERTAIN
AIR CLEANER IS CLEAN AND ATTACH
ED TO THE carburetor before
ADJUSTING CARBURETOR DO NOT
MAKE UNNECESSARY ADJUSTMENTS
FACTORY SETTINGS ARE SATISFAC
TORY FOR MOST APPLICATIONS AND
CONDITIONS.
Never attempt to change maximum engine speed It is
pre-set at the factory and should be changed only by
a qualified service technician who has the necessary
equipment,
The carburetor may need re-adjusting if engine lacks
power or does not idle properly If adjustments are
needed, proceed as follows.
To Adjust Carburetor:
1. Close needle valve (See figure 16} clockwise
(Oi' finger tight only Forcing may cause damage.
Then open 1-1/2 turns counterclockwise ik~h)
2. Start engine and allow to warm for five minutes.
3 With throttle in RUN position, close needle valve
clockwise until engine starts to lose speed
{lean mixture) Then slowly open needle valve
counterclockwise ik~N) until engine JUST BEGINS
to run unevenly This mixture should be rich enough
for best performance under load.
4 Place throttle control in IDLE position:
a If engine idles, no further adjustment is
necessary.
b. If engine idles too fast, turn idle speed
adjusting screw counterclockwise until
slower speed is obtained
c If engine dies, turn idle speed adjusting screw
1/4 turn clockwise l/^i Place throttle
control in FAST position arid restart engine,
d Move throttle control to IDLE position If
engine does not idle, repeat step c
Test the engine by operating the chipper-shredder,
If engine lends to stall or die out, it usually
indicates that the mixture is slightly lean and it may
be necessary to open iX">) the needle valve slightly
to provide a richer mixture This richer
mixture may cause a slight unevenness in idling.

any repairs or maintenance-
ENGINE LUBRICATION
Your four cycle engine will normally consume some oil;
therefore check engine oii level regularly - approxiniateiv
every five hours of operation and before each usage
Stop engine and wait several minutes before checking
oii level, With engine level, the oil must be even with
the oil fill (refer to figure 7) Change engine oil after the
first two hours of operation, and every twenty five
hours thereafter
1. Drain oil while engine is warm
a. Remove oil drain plug Refer to figure 7
b. Tip the chipper-shredder forward, and catch oil
in a suitable container
c. When engine is drained of all oil. replace drain
plug securely.
2 Refill with fresh oil Above 32°, use oil labeled
SAE 30W or 10W30 Below 32°, use oil labeled
5W20 Capacity is 1-1/4 pints Refer to "Gas and
Oil Fill-Up" on page 6
3- Replace oil fill plug.

equipped with a spark arrester screen assembly, remove
every 50 hours for cleaning and inspection. Replace if
damaged
CLEAN ENGINE
Clean engine periodically Remove dirt and debris with
a doth or brush Cleaning with a forceful spray of water
is not recommended as water could contaminate the
fue! system.
Yearly or every 50 hours, whichever occurs first, remove
the blower housing and clean the areas shown in figure
18 to avoid overspeeding, overheating and engine
damage Clean more often if necessary.

LUBRICATION
Wheels ^ The wheels require no lubrication.
Flails and Fingers - if the unit is disassembled for any
reason, lubricate the flails and fingers with a light oil
(engine oil may be usedi
CUTTING BLADE
The cutting blade may be removed for grinding or
replacement as follows
1
Lower the upper guide extension
2,
Block up the housing. See figure 20,
3,
Remove the four elastic lock nuts from the back
of the housing using a 1/2" wrench Refer to figure
14, Separate the shredder into two halves
4,
Remove the back-up plate, See figure 20
NOTE
When reassembling, make certain the
opening on the back up plate is toward
the bottom of the unit The back up plate
may be reversed to provide a new cutting
edge.
When sharpening the blade, follow the original angle
of grind as a guide It is extremely important that each
cutting edge receives an equal amount of grinding to
prevent an unbalanced blade An unbalanced blade will
cause excessive vibration when rotating at high speeds
and may cause damage to the unit
The blade can be tested by balancing it on a round shaft
screwdriver or nail Remove metal from the heavy side
until it balanced evenly See figure 21
When reassembling the blade, tighten to between 375
and 450 inch pounds, or lacking torque wrench, tighten
securely
FLAILS AND FINGERS
The flails and fingers may be reversed when they
become dull It is suggested that thts procedure be
