UNIT OPERATION
1. CONNECTING UNIT TO TOWING VEHICLE:
Connecting the Model 1695 Trail-Vac to a towing vehicle is fast and easy – simply align
the hole in the forward section of the Trail-Vac’s A-frame hitch with the rear hitch mount
of the towing vehicle, and secure with a heavy-duty hitch pin (not supplied).
2. STARTING THE ENGINE
NOTE: If you experience problems with your engine that cannot be satisfactorily resolved by
following the instructions contained within the engine manual, contact your local engine dealer, or
call the toll-free service number listed in the repair section of the engine manual. All engine
service, warranty or otherwise, is required to be performed by a manufacturer-authorized service
center. Giant-Vac Mfg., Inc. is neither authorized nor responsible for any type of warranty engine
service, nor is it equipped to perform any such service.
BEFORE STARTING ENGINE:
•Be sure to read your engine manual carefully and thoroughly before attempting to
start the engine.
•Be sure that the unit is completely assembled, and all safety guards and
components are in place.
•Be sure to check engine’s oil and gasoline*. (See engine manual for recommended
oil and gasoline specifications.) Never check the engine while it is running or while
you are smoking. Check only when engine is cold.
*All machines are shipped without oil or gasoline unless otherwise noted.
•Be sure that red fuel valve on engine is set to open position.
TO START ENGINE :
•Set throttle control up to “full” position. If engine is cold, set choke by pulling out
choke handle.
•Turn ignition key and hold until engine starts. (If engine fails to start within a
reasonable amount of time, discontinue and check engine manual for further
instructions.)
•After engine starts, release ignition key, move throttle control down to approximately
half, and turn off choke as required.
2

TO SHUT ENGINE DOWN :
•Allow engine to idle for 2-3 minutes before shutting down.
•Turn ignition key to ‘off’ position.
•If engine is not to be started for a prolonged period, turn red fuel valve to closed
position.
3. OPERATING THE UNIT:
ADJUSTING THE NOSE CONE:
Adjustable rubber flaps along the entire perimeter of the large 48” nose cone * make
your Model 1695 Trail-Vac suitable for virtually any surface. To adjust the flaps, simply
loosen the bolts securing the flap bolt plates to the nose cone body, and slide the flap
assembly up or down to suit the particular application. Generally, the harder and
smoother the surface (such as parking lots), the closer to the surface the flaps should be
adjusted; the softer and rougher the surface (such as grassy fields), the higher the flaps
should be set. Experience will be your best guide. As a rule of thumb, however, the
rearmost flap should always make contact with whatever surface the Trail-Vac is
operating on.
* Model 1695 MO E has a rotary mower attachment in place of the nose cone. This
option consists of an intake flange that attaches directly to the power unit, a six-foot
length of 6” diameter hose, two 6” hose clamps, and a special universal chute that
attaches to the discharge portion of a mower deck, in place of the deflector. The chute
is adjustable and will fit most model tractors.
UTILIZING THE OPTIONAL NOSE CONE MOUNT HOSE KIT:
In addition, the nose cone is designed to accept an optional intake hose kit, making the
Trail-Vac an incredibly versatile piece of debris removal equipment. This option allows
for easy access into areas that the Trail-Vac is unable to maneuver into. For further
information regarding this and other optional accesories, please refer to the options
section further along in this manual.
To attach the hose kit, first remove the auxiliary intake cover (Parts List Ref. # 36, Sheet
1) from the upper portion of the nose cone body. Then, using the same mounting
hardware, fasten the intake flange to the auxiliary intake, tightening the mounting bolts
securely. Next, slide one hose clamp onto one end of the intake hose, approximately 1-
2” from the end. Slide this end of the hose onto the intake flange, and tighten the clamp
securely. Slide the other hose clamp onto the loose end of the hose in like manner, then
slide the end of the hose onto the intake nozzle. Tighten clamp securely.
To utilize the intake hose kit, remove the nut, lockwasher, and inner door lever clip from
the left side of the nose cone body (Ref #’s 10, 11, 12; refer to Parts List Sheet 1), and
flip the door lever up to a vertical position. This will close the bottom portion of the nose
cone, deflecting all suction to the auxiliary intake. (Helpful hint: If intending to utilize the

hose kit option for an extended period of time, simply invert the clip, slide it back onto the
stud, and secure it with the lockwasher and nut. This will prevent the clip from being lost
or misplaced.)
DUMPING THE LEAF BOX:
Your Giant-Vac Model 1695 Trail-Vac has a 2 cubic yard* self-dumping leaf box. When
the box is full, simply back the unit up to the desired dumping area **, loosen the two
handle nuts on either side of the back door, swing the two pivot lock bolts out of the way,
lift the spring-loaded back door, and the debris will slide out. If necessary, pull the unit
forward a few feet to ensure complete emptying of the box. Be sure to close and lock
the door before resuming operation.
* Approximate holding capacity
** Before backing up, always make a visual assessment of the area behind the
Trail-Vac, making sure there are no people (especially children) or objects behind
the machine that could be backed into or run over. Failure to do so could result in
serious injury, as well as severe machine and/or property damage.
UNIT OPTIONS:
NOSE CONE MOUNT HOSE KIT (MODEL 1696):
This hose kit contains an intake flange that mounts onto the nose cone’s auxiliary intake
(the hole in the upper portion of the nose cone body, covered by the round cover plate),
a ten-foot length of 6” diameter hose, an intake nozzle (complete with handle grip), and
two 6” hose clamps. This handy accessory allows easy access to hard-to-reach places.
DIRECT MOUNT HOSE KIT (MODEL 1606):
This hose kit consists of a flange that bolts directly onto the power unit in place of the
nose cone, a ten foot length of 10” hose, an intake nozzle, and two 10” hose clamps.
The most popular application is for cleaning out such places as shrubbery beds.

MAINTENANCE AND STORAGE
•Follow implicitly the engine manufacturer’s recommendations for maintenance.
•Never make any adjustments to the Trail-Vac until the engine is off and the spark
plug wire is disconnected.
•If carburetor adjustment is necessary, stand to one side and keep feet and hands in
the clear while making adjustments.
•Keep engine free of accumulations of grass, leaves or excessive grease. An
accumulation of these combustible materials may result in a fire.
•Store gasoline in a safe and approved container in a cool dry place.
•Keep the Trail-Vac and fuel container in locked storage to prevent children from
playing and/or tampering with them.
•Do not store gasoline powered equipment or fuel containers in a basement or any
closed area where heating or heat appliances or open pilot lights are present, unless
the fuel is completely drained from the power equipment and the fuel containers.
