Assembly
NOTE: Items in ( ) can be referenced in the Parts Illustration and Parts List on pages 17-24.
1. SECURELY ATTACH unit to the bed of a truck or to a trailer, so that the exhaust discharges into an
enclosed container. NOTE: This unit must be securely mounted to the bed of a truck or to a trailer before
operating.
2. ATTACH the hose boom (item 2) to hose (item 3) by sliding the boom through the rings on the top of the
housing.
3. ATTACH hose (item 3) to housing intake, using hose clamp (item 25) making sure to place the safe-
ty switch under the clamp. Then place the clamp (item 25) over and around the end of the hose to be
attached to the housing. Slide the hose onto the housing intake and place the shut off switch under the
clamp. Make sure the shut off switch is pressed in or the vacuum will not start, and clamp the hose to the
intake. (See page 8 for illustration)
4. ASSEMBLE nozzle handle (item 6), to nozzle intake (item 9), using screw (item 7), eye bolt (item 8),
washers (item 10) and lock nuts (item 11).
5. ATTACH assembled nozzle to hose using hose clamp (item 25). Before tightening hose clamp, position
nozzle handle upward when hose is stretched to prevent twisting. Load on hose assembly during operation.

Assembly Continued
NOTE: Items in ( ) can be referenced in the Parts Illustration and Parts List on pages 17-24.
6. ASSEMBLE hose band (item 2) around hose and secure chain between the anges of the hose band using
capscrew and lock nut (not pictured in Parts Drawing 1). Attach the chain (item 12) to the boom and the screw
on the hose band. (See “ADJUSTING HOSE BOOM” on page 11).
7. SECURELY ATTACH exhaust elbow (item 31) capturing both anges inside the clamp, then rmly tighten
the clamp, securing the elbow to the housing (see “MOUNTING” below).
8. INSTALL a standard 12 volt lawn and garden battery “U1” series (not included) with at least 240 cold crank-
ing amps anWd a 40 amp hour rating by using battery bracket (item 60), hold down rods (item 59), washers
and lock nuts (Not pictured in Parts Drawing 4).
9. ATTACH the red battery cable to the + terminal and the black battery cable to – terminal on the battery.
Mounting Main Unit
General: Unit must be securely mounted to a
trailer, truck bed, or other similar surface before
use. Do not use this unit in a freestanding posi-
tion. Unit is not stable until it has been secured
in place.
Secure unit by bolting through the base of the
unit and through the mounting surface using
3/8" dia. bolts, with washers and locking nuts
(see Fig. 10).
Mounting: Fig. 11 illustrates the mounting po-
sition to the trailer (Billy Goat Part No. 791152)
available from your Billy Goat dealer. The unit
is only mounted one way.

Assembly Continued
Mounting Exhaust Elbow (See Fig. 12)
Note: this process requires two people, one to
support the exhaust elbow and one to attach
plates and hardware.
1. Remove the hardware from the clamps (items
30 and 40).
2. Apply good quality grease to the top and
bottom of the toothed plate of the exhaust elbow
(item 31). Also grease top surface of housing and
bottom of clamp plates where the gear will rotate.
3. Place the exhaust elbow on the chute with the
teeth of the ange against the worm gear and the
exhaust holes, aligning.
4. Place the two bottom plates (item 35) on the
opposite edges beside the elbow teeth aligning
the holes.
5. Place the top plates (item 34) on top of the
lower plates aligning the holes.
6. Secure the assembly with a plate half on top of
the elbow ange and a plate half on bottom of the
housing ange using 6, 1” carriage bolts and 6
lock nuts (removed hardware in step 1).

Operation
Vacuuming Operation
Important
With the machine off and spark plug disconnected
check the condition of the replaceable liner before
every use and replace if necessary.
Exhaust Direction and Distance
Exhaust direction and distance are controlled by
the rotation of the exhaust elbow. Typically debris is
aimed to discharge to the rear of the container. The
direction of discharge is adjusted by turning the crank
on the exhaust elbow clamp and rotating the elbow to
the desired direction.
Note: Elbow is heavy. Use caution when adjusting.
Never stand directly under the elbow while adjusting
direction of exhaust. Never direct exhaust into an
area where bystanders may cross the path of the
debris.
Intake Operation
With the fully assembled machine running, move
the nozzle in sweeping motions over debris. Always
allow air to ow into the nozzle along with the debris.
Do not completely block the nozzle when vacuuming,
it will reduce performance, and increase clogging
(See Fig. 13). For removal of heavier debris, or debris
that is stuck to the ground, rock nozzle forward to
concentrate suction power around the debris (See
Fig. 14).

BHose Band (stretch hose out before clamping).
Adjusting Hose Boom
Properly adjusting the boom prevents most hose
clogs from occurring and maximizes vacuum
performance by keeping the hose straight and
perpendicular to the housing (see Fig. 15). Raise
or lower one of the attachment links to a different
area on the chain to make height adjustments.

Operation Continued
Unclogging a Clogged Hose
With engine running and unit secured to a trailer, truck bed, or other similar surface, fully
stretch hose in a straight line to dislodge the clog. If the clog will not clear, turn unit off, and
allow engine to come to a complete stop. Remove hose and manually clear the hose clog.
Note: The clogged debris may be sharp. Always wear durable gloves when removing clogs.
Unclogging a Clogged Housing or Exhaust Elbow
1. Turn engine off and wait for impeller to come to a complete stop.
2. Disconnect spark plug wires and battery cables.
3. Remove the hose from the housing and determine where the clog is located.
4. If possible, clear the clog through the intake opening. It may require removal of the intake
adaptor (item 6) to allow access to clear the housing.
5. If clog is in the elbow, carefully remove the elbow. Remove elbow by removing the bolts
and nuts on the elbow clamp so that the plates can be removed.
Note: Elbow is very heavy. Do not stand directly under elbow during removal!
Danger: The clog may contain sharp materials. Clear the clog wearing durable gloves!
Reconnect spark plug wire.
Hose Care
To increase hose life, periodically rotate hose and reposition nozzle and coupler on front
plate of unit. This ensures that the hose will not wear on only one side, further increasing its
life.
Keep hose as straight as possible and avoid sharp bends during operation for best pick-up
and to avoid clogs. Never drag hose. Always remove and store hose before transporting
unit. Store hose straight and at to maintain exibility for next use.
Maintenance
Interlock System
With hose coupler installed (as shown in Fig. 16) the
switch is open and engine is not grounded out, allow-
ing engine to run. Hose must be installed and switch
lever must engage switch for engine to start.
