ATTACHING THE CHIPPER CHUTE AND
SUPPORT BRACKET (See figure 4)

• Remove the two hex !ock nuts from the hex bolts
which secure the right side of the upper handle to

the lower handle, Leave bolts and washers in

place.

• Remove three cupped washers and 5/16" hex nuts
from the weld studs beside the opening on the right
side of the chipper-vacuum,

• Place the chipper chute in position over the weld

studs (slot goes at the bottom). Secure with cupped
washers and hex nuts just removed.

NOTE: Only tighten the three nuts one or two threads

for ease of further assembly.

NOTE: Cupped side of the washer goes against the
chipper chute. See figure 2 to identify cupped side of

washer,

• Remove the two hex bolts, flat washers and nuts
which are attached to the support bracket.

• Attach the support bracket to the bottom of the
chipper chute loosely using the hardware removed

previously. HEADS OF THE HEX BOLTS AND
WASHERS GO TO THE INSIDE OF THE

CHIPPER CHUTE.

• Place the support bracket over the [wo bolts in the

handle. Pushing UP on the chipper chute will aid

the alignment of the holes in the support bracket
with the bolts in the handle.

• Tighten all hardware securely on the chipper chute,
support bracket and handle.

ATTACHING THE CLUTCH CABLE

The clutch cable has been assembled at the factory.

Loosen the hex nuts at the cable bracket. Hook the
"Z" end o_=the cable into the drive clutch handle from

the outside to the inside as shown in figure 5A. Pliers

will aid in assembly.

CLUTCH CABLE ADJUSTMENT

Adjust the hex nuts at the cable bracket so there is no
slack in the cable, but the cable is NOT tight. Do not
overtighten the cable. See figure 5B.

To check the clutch adjustment, oroceed as follows.

• Push tl_e chipper-vacuum backward and forward
with the drive clutch handle released. It should

move freely.

If it does not, loosen both hex nuts at the cable
bracket. See figure 5B. Turn bottom nut counter-

clockwise to loosen the cable.

• Engage the drive clutch handle (hold against upper

handle), and try to push chipper-vacuum backward
and forward. The wheels should lock up.

If the wheels do not lock up, loosen both hex nuts
at the (:able bracket, Turn bottom nut clockwise to

tighten the cable.

• Recheck adjustment, Tighten both hex nuts when

correct adjustment is reached.

ing certain it is over the rib on the discharge chute.
See figure 6.

• Place the four straps on the top of the bag over
upper handle, hooking them on studs. See figure 7.

NOTE: Be sure the bag goes under the drive clutch
handle.

• Squeeze the clamp on the drawstring, and puff the
drawstring tight. Release the clamp.

INSTALLING THE SHIFT KNOB

Remove the cardboard protecting the threads. Thread
the shift knob onto the end of the shift lever.

TAMPER PLUG
The handle on the tamper plug must be in the vertical

position as shown in figure 8. To determine which
side of the tamper plug is up, match the angle of the

tamper plug to the angle of the chipper chute.

MEETSANSI SAFETY STANDARDS

Sears chipper-vacuums conform to the safety standards of the American National Standards InsUtute.

OPERATINGCONTROLS(See figure 9)

SHIFT LEVER--The shift lever determines ground

speed. It may be placed in one of eight positions.
Forward--one of six speeds. Position number one (1)

Esthe slowest. Position number six (6) is the fastest.

Reverse--two reverse (R) speeds. "R" (all the way to

the right) is the faster of the two.

DRIVE CLUTCH HANDLE (BAIL)--Squeezing the

drive clutch handle against the upper handle engages
BEFORE USING YOUR CHIPPER-VACUUM, AGAIN REFER TO THE "SAFETY RULES" AS SHOWN ON

PAGE 2 OF THIS MANUAL. ALWAYS BE CAREFUL.

The operation of any chipDer-vacuurr can result in foreign objectsbeing thrown into the eyes, which
can result in severe eye damage. Always wear the safety glasses providedwith the chipper-vacuum or
eye shields before chi_pJng, or while _erforming any adjustments er repairs We recommend Wide

Vision SafetyMask for over spectacles or standard glasses availableat Sears Retail er Catalog Stores.

TOSTOPENGINE

• Move throttle control lever to STOP position. See
figure 9.

• Disconnect spark plug wire and move away from
spark plug to prevent accidental starting while
equipment is unattended.

HOW TO USE YOUR CHIPPER-VACUUM

EQUIPPED WITH A SAFETY SWITCH ON

_IL WARNING: YOUR CHIPPER-VACUUM iS

TO ENGAGE DRIVE

IMPORTANT: Always release the drive clutch
handle before moving the shift lever.

• With the engine running near top speed, move shift
lever into one of the six FORWARD _ositions or

two REVERSE positions. Select a speed appropri-

ate for the conditions that exist. Use the slower
speeas until you ere familiar with the operation of

the chipper-vacuum.

e To engage the wheel drive, hold the drive clutch

handle against the chipper-vacuum handle.
Releasing the drive clutch handle stops the wheels

from driving. Retease the drive clutch handle to
slow down when negotiating an obstacle making a

turn or stopping. Engage slowly to prevent front
wheels from lifting up.

NOZZLE HEIGHT ADJUSTMENT

The height adjustment knob is located on the right
hand side of the chipper-vacuum. See figure 10. Tun-

the knob clockwise to raise the nozzle. Turn the knob
counterclockwise to lower. (Be careful not to turf

knob too far--rod could come out of ferrule.)

CHOKE LEVER--Used to enrich the fuel mixture in

the carburetor when starting a cold engine.

STARTER HANDLE--Used to manuatty start the

THROTTLE CONTROL--Controls engine speed and
stops the engine.

The best height for the nozzle will vary according to

the conditions. Adjust the height of the nozzle to find
the setting which gives the best performance for the

operating conditions. In general, raise the nozzle to
vacuum a thick layer of leaves; lower the nozzle for

smooth surfaces.

USING THE CHIPPER CHUTE

Do not a_empt to chip any materiel other than vegeta-
tion found in a normal yard (i.e., branches, leaves,
twigs, etc.). Matedal such as stalks or heavy branches

up to 3" in diameter may be fed into the chipper
chute. See figure 11

WARNING: MATERIAL UP TO A MAXI-

MUM OF 3" IN DIAMETER MAY BE FED
INTO THE CHIPPER CHUTE. DO NOT

ATTEMPT TO CHIP ANY MATERIAL

LARGER THAN 3" IN DIAMETER,
PERSONAL INJURY OR DAMAGE TO

THE MACHINE COULD RESULT,

If necessary, use the tamper plug provided to push
material into the chipper chute. See figure 8. NEVER

PLACE HANDS INSIDE CHIPPER CHUTE. PIace

tamper plug inside chipper chute when not in use to

deaden the sound.

FIGURE 11.
IMPORTANT: There is a flail screen located inside

the housing in the discharge area. If the flail screen

becomes clogged, remove and clean as instructed in

the Service and Adjustment section on page 14.

For best performance, it is important to keep the

chipper blades sharp. If the composition of the

material being discharged changes (becomes stringy,
etc.) or if the rate at which the material is discharged
slows down considerably, it is likely that the chipper

blades are dutl and need to be sharpened or
replaced. Refer to Service and Adjustments sections.

TO EMPTY BAG
Open the large zipper on the bag to empty the bag.
See figure 12. Be certain the zipper is closed when

operating the unit.

GASAND OIL FILL-UP

OIL

Only use high quality detergent oil rated with API
service classification SF, SG or SH. Select the oil's

viscosity grade according to your expected operating
temperature.

Colder < 32°F _- Warmer

5W30 SAE 30

NOTE: Although multi-viscosity oils (5W30, 10W30,

etc.) improve starting in cold weather, these multi-
viscosity oils will result in increased oil consumption
when used above 32°F. Check your oil level more

frequently to avoid possible engine damage from

running low on oil.

• Use engine oil provided. Remove oil fill dipstick.

See figure 13. With chipper-vacuum level, use a

funnel to fill engine with oilto FULL mark on dipstick.

Capacity is approximately 26 ounces. Be careful not

to overfill. Oil bottle provided contains 27 oz. of oil.
Tilt chipper-vacuum toward the left (from behind the

hopper), then re-level. Check oil level. Refill to FULL
mark on dipstick if necessary. Replace dipstick and

tighten.
