5. Holding the adapter bracket and the deck adapter
together, position the deck adapter on the mower
deck. Keeping the edge of deck adapter as close as
possible to the offset in the adapter bracket, see if the
slot in the adapter bracket can be aligned with one
or two of the deflector holes in your mower deck's
discharge opening. If the bracket can not be located
correctly using existing holes, it will be necessary to
drill one or two 5/16" diameter holes in the deck. See
figure 26.
7. With deck adapter positioned correctly over the dis-
charge opening, use the adapter bracket as a tem-
plate and drill three 9/32" diameter holes in the top of
the deck adapter. See figure 28.
8. Bolt deck adapter to bracket using three 1/4" x 3/4"
bolts, nylon washers, 1/4" flat washers and 1/4" lock
nuts. Nylon washers should be against the inside of
the deck adapter. See figure 28.
Use existing holes or drill 5/16"
diameter hole or holes.

1. Cut out two templates and place on deck adapter as
shown in figure 29. Tape smaller one on top and larger
one on the side and bottom. After they are in place,
carefully mark around the templates, then cut out
adapter to obtain correct opening.
1. Tape 46" template onto deck adapter. Mark and then
cut out adapter .
2. Fasten the angle bracket and the mounting bracket to
the mower deck as shown in figure 30. Use two 5/16"
x 3/4" carriage bolts, 5/16" flat washers and 5/16" lock
nuts. The bolt heads go on inside of mower deck.
2. Bolt end of mounting strap to the 5/16" bolt on the
mower deck. The other end of the strap will bolt to
a hole in the deck adapter, which must be drilled.
Position the adapter on the deck, then drill a 5/16"
hole in the bottom of the adapter that will align with
the hole in the strap. Fasten the adapter to the strap
using a 1/4" x 3/4" hex bolt, 1/4" flat washer, nylon
washer and 1/4" nylock nut. See figure 29.
3. Drill two 5/16" diameter holes in the deck adapter
that will align with the holes in the angle bracket and
the mounting bracket. Assemble the deck adapter to
both brackets using two 1/4" x 3/4" hex bolts, 1/4" flat
washers, nylon washers and 1/4" nylock nuts. See
figure 30.
3. Assemble end of hose and hose clamp over the round
opening of deck adapter and tighten clamp.

HOW TO USEYOUR CHIP-N-VAC
BEFORE STARTING
1. Your Chip-N-Vac engine is shipped without oil or
CAUTION: Vehicle braking and stability
gasoline. Service the Chip-N-Vac engine with oil and
gas as instructed in the separate engine manual.
2. Inspect the Chip-N-Vac to make sure all covers (rear
door, vinyl boot, elbow, hose adapter, hose and deck
adapter are properly attached.
may be affected with the addition of an
accessory or an attachment. Be aware of
changing conditions on slopes.
1. Inspect the Chip-N-Vac to make sure all covers (rear
door, vinyl boot, elbow, chipper chute with tamper
plug, hose adapter (nozzle), hose and deck adapter
are properly attached.
3. Check tires for proper inflation (12 - 14 lbs).
WARNING: Never fill fuel tank indoors, or
with the engine running, or while the engine
is hot. Do not smoke while filling tank.
2. Check tires for proper inflation (12 - 14 lbs).
3. Check oil and gas in Chip-N-Vac engine.
4. Begin operation at low speed, adjusting forward speed
to match grass height and/or moisture condition to
prevent clogging.
5. Do not attempt to vacuum up any material other
than vegetation found in a normal yard, such as light
branches, leaves, twigs, etc.
HOW TO STOPYOUR CHIP-N-VAC
1. To stop engine, move the throttle control lever to the
OFF position.
2. Disconnect spark plug wire from plug to prevent ac-
cidental starting while equipment is unattended or is
being worked on.
WARNING: Should your Chip-N-Vac be-
come clogged, shut off tractor and Chip-N-
Vac engines. Before attempting to unclog,
remove wire from spark plug to prevent
accidental starting.
CAUTION: The muffler and adjacent
areas are hot!
6. To empty cart, shut off tractor engine and set brake.
7. Shut off Chip-N-Vac engine.
8. Remove rear door from cart.
9. Release the latch holding cart down to the tongue by
pulling up on the latch lever. See figure 31.
10. Using a rake or suitable tool, pull the grass clippings
HOW TO STARTYOUR CHIP-N-VAC
CAUTION: To avoid possible injury, be
sure that no one is near the cart before
releasing the latch.
WARNING: Never start or run the
engine without all covers being properly
attached to the blower housing and cart.
and/or leaves out of cart.
11. After cart is emptied, secure cart to tongue with latch
and reattach the rear door and the vinyl boot.
1. Check oil and gas in Chip-N-Vac engine.
2. Attach spark plug wire to spark plug.
3. Move choke lever on engine to CHOKE position.
(A warm engine may not require choking.)
4. Move throttle control lever on engine to FAST position.
5. Grasp starter handle 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.
6. Pull rope with a rapid, continuous, full arm stroke.
Keep a firm grip on starter handle. Let rope rewind
slowly. Do not let starter handle snap back against
starter.
7. Repeat instructions in two preceding paragraphs until
engine fires. When engine starts, move choke control
gradually to RUN position.
FIGURE 31
16
USING THE CHIPPER CHUTE
1. Material such as stalks or heavy branches up to 3" in
diameter may be fed into the chipper chute as shown
in figure 32.
2. Be sure to wear eye protection and gloves when
feeding material into the chipper chute.
3. Use the tamper plug, not your hands, to force material
down through the chipper chute.
4. 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 of discharge slows down
considerably, it is likely that the chipper blades are dull
and need to be sharpened or replaced. Refer to the
Service and Adjustments section, on page 19.
WARNING: Do not attempt to feed any
material larger than 3" in diameter into the
chipper chute. Personal injury or damage to
the machine could result.
DANGER: Keep hands out of chipper
chute. Rotating blades in impeller housing
can cause serious injury. Use the tamper
plug to help push material down into the
chute.

any repairs or maintenance.
CHECK FOR LOOSE FASTENERS
1. Make a thorough visual check of the Chip-N- Vac for
any bolts and nuts which may have loosened. Retight-
en any loose bolts and nuts.

as instructed in the separate engine manual.
2. Service air cleaner every 25 hours under normal
conditions. Clean every few hours under extremely
dusty conditions. Poor engine performance and

instructed in the separate engine manual.
LUBRICATION
CLEANING
1. At the beginning of each season, lubricate the latch,
latch pivot bolt, and the axle where the hitch tongue
pivots, with a light machine oil.
2. At least once a season, grease or oil the wheel bear-
ings. Use automotive wheel bearing type grease or 20
weight oil.
1. Make sure the cart, the side and front panels and
top are cleaned after each use. Grass clippings and
leaves left in the cart will mildew and cause damage if
not cleaned out.
2. Clean the engine regularly with a cloth or brush.
Keep the cooling fins on the engine housing clean
to permit proper air circulation which is essential to
engine performance and life. Be sure to remove all dirt
and debris from muffler area.
