Insure spark plug wire and rubber boot is attached to spark
plug (See Engine Manual).
Turn fuel shut-off valve to “ON” position (if so equipped)
(see Engine Manual).
Push stop switch to “ON” pq:ition (if so equipped).
Move choke control lever to “CHOKf3FULL CHOKI?
positiin. (See Engine Manual)
Move throttle control lever to ‘FAST/OWRUN” position.
Grasp starter handle (See Engine Manual) and pull rope
out slowly until engine reaches start of compression cycle
(rope will pull slightly harder at this point. Let the rope rewind
slowly. .
Pull the rope with arapid, continuous, full arm ~troke. Keep
afirm grip on start handle. Let rope rewind slowly. DO NOT
let starter handle snap back against starter. ~~
Repeat preceding two (2) instructions until engine fires;
When engine starts, move choke lever on engine halfway
between ”CHOKE/FULLCHOKF and”RUN/NO CHOK15.
Move throttle control to idle rm.ition for afew minutes to
allow engine to warm-up. When engine is warm move
choke lever to “RUN’* position.
NOTE Inorderto idle srncmthly, anew engine mayrequirethree
(3) to five (5) minutes running above slow idle speed. Idle speed
has been adjusted to be correct after this break-in period.
TO STOP ENGINE:
.Move throttle ~ntrol lever to”* OFF/STOP/SLOW” position.
(See Engine Manual) .
.Push stop switch to ‘OFF” position (if so equipped).
.Do not choke carburetor to stop engine. Backfire or engine
damage may resuft if choke is used to stop engine.
NOTE: Close fuel shutoff va~e (if so equipp+) when transporting

●Bulky material, such as stalks or heavy branches (anything
over 1/2” diameter, up to 3“ in diameter), should be fed into
the Chipper chute (See FIG 5-OP).
For best performance, itisimportant tokeepthe shredding blade
and the chipper blade sharp. Refer to service and adjustment
section, pages 12, 13. If the composition of the material being
discharged changes (becomes stringy, etc.) or il the rate at
which the material feeds’~n slows down considerably, it is likely
that the shredding blade and/or Chipper blade is dull and need
to be sharpened or replaced.

PERFORMING ANY REPAIRS OR MAINTENANCE.
GENERAL RECOMMENDA’fiONS:
.Periodically check all fasteners and be sure they are tight.
●Follow the Service Recommendation Schedule, in SERVICE
AND ADJUSTMENT section of this manual.
CHIPPER/SHREDDER LUBRICATION:
Lubricate the transport wheel hubs occasionally, with a
good quafii motor oil.
The rotating Hopper assembly requires lubricating 10
maintain optimum performance. Approximately every fiie
(5) hours of operation, before each use, and before storage,
Iubriite the Hopporassembly rotating plate. Using a hand
grease gun, filled with a good quality, all-purpose grease,
lubricate the three (3) zerk fittings found on the Hopper
assembly retainer ring.
Fill each zerk with approximately five (5) shots of grease.
Rotate Hopper assembly to the ground as shown in FIG.!! -
OP and apply five (5) more shots of grease to each of the
three (3) zerks. Rotate Hopper assembly several times to
spread lubricant around. NOTE: Should Iubr”kati.ng the
Hopper assembly fail to provide adequate rotat”mn, remove
the entire Hopper assembly from unit (See FIG.2-SERV).
Clean debris from all rotating parts, repface or repair any
damaged parts, reassemble Hopper assembly securely to
unit and lubricate according to procedure above.
Caster wheel (optional) approximately every ten (1O)hours
of operation and befo~e storage, lubricate-the ze~ fitting
found above the caster wheel with three (3) shots of a good
quality, all purposo grease.
●ENGINE LUBR1CATION: ‘“
Refer to the separate engine manual for engine maintenance
instructions. Maintain engine oil as instructed in the separate
engine manual packed with your unit. Read and follow instruc-
tions carefully.
AIR CLEANER -
Service aircleanerevery (25) hours or every season, which eve!
comes first. Clean every few hours under extremely dusty
conditions. Poor engine performance and flooding usua.fly indi.
cates that the air cleaner should be setviced. To service the ail
cleaner, refer to the separate engine mairual packed with youl

Manual to avoid over-speeding, over-heating end engine dama-
ge. Clean more often if necessary. ,,
MUFFLER
Do not operate the Chipper/Shredder Withoq amuffler or
tamper with the exhaust system. Damaged mufflers or spark
arresters could geate afire hazard. Inspect periidk.aily and
replace if necessary. If your engine is equipped with aspark
arrester screen assembly, remove every ffiy (50) hours for
cleaning and insp~ion. Replace if damaged.
CLEANING
.TheChipper/Shredder may be cleaned by running water
from ahcce through the Shredder Hopper assembly and

TO REDUCE THE RISK OF INJURY, ALWAYS WEAR
HEAVY GLOVES WHEN HANDUNG THE CLflllNG
BLADES.- THE CUITiNG EDGES ARE SHARP AND
CAN CAUSE SEVERE INJURY.
SHARPENING OR REPLACING
CHIPPER BLADES:
Over aperiod of time, the cutting blade will dull. Sharpen or
replace the blade when the chipper no Iongw cuts as efficiently
as when new.
●Discard acracked or severely nicked blade because it
could break apart and cause personal injury.
●Sharpen ablade that isdullorthat has only minor nicks; The
blade is made from tempered steel and is extremely hard -
do not attempt to sharpen with a hand file. We recommend
that you take the blade to aprofessional sharpening service
for proper sharpening. Allgrinding must be done flat and
uniform along the beveled edge only, being sure to maintain
the orginal 45° cutting angle.
TO REMOVE AND INSTALL THE
CHIPPER BLADE:
Disconncd spark plug wire and move it away from spark
plug.
Ftemove the Chipper chute by removing three (3) hex nuts
and washers (iorns B). A1/2” sockot with ~xtension is
required (Soo FIG.-3 ASSY).
Rota! ethe Hopper assembly to the ground as shown in FIG.
3-OP.
Removo tho three (3) hex locknuts (item A) and flatwashers
(iem B) from the housing studserts and carefully separate
the Hopper assembly from the remainder of the unit (See
FIG. 2-SERV. &ADJ.)
Remove the three (3) bushings (item C) and stationary
plate (item D). (See FIG. 2-SERV. &ADJ) NOTE: When
reassembling, make certain the opcximg of the stationary
plate is toward the bottom of the unit and the offset, is facing
toward the impeller assembly.
Rotate the impeller assembly by hand until you locate the
Chipper blade in the Chipper chute opening.
Prevent” the impeller ,assembly from turning in a
counterclockwise direction by wedging ablock of wcod
be[wecn one of the fan blades and the wall of the’housing
or, insert athick, hardwood dowel (item A) through the slot
below the blade and into the Chipper chute opening in the
wall of the housing. (See FIG. 1-SERV &ADJ).
●Remove the blade, using a3/16- anon wrench (item B) on
the outside of tho bfade and 1/2” wrench (item C) on [he

facing away from the impellorassomtiy and pointing toward
the sfot in the impeller assembly. Tghten locknuts securely
(if using atorquo wrench, tighten lo~nuts to 20 ft-lbs). -
●The shredding bfade is reversible and can be reversed
before any sharpening should need to be performed.
●After both sides of the blade have become dull, nicked, etc.
to the point of reducing performance, the blade needs to be
sharpened or replaced.

edge receives an equal amount of grinding to prevenl n
unbalanced blade. An unbalanced blade will caus
excessive vibration when rotating al high speeds and may
cause damage to the unit.
The blade can be tested for balance by balancing it on a
round shaft screwdriver or nail. Remove metal from the
heavy side until it is balanced evenly (SEE FIG. 4-SERV &
