1. Breakage or Damage During Shipment
The transportation company is fully responsible for all shipping damage and will resolve problems promptly if you handle it
correctly. Please read these instructions carefully.
Examine the contents of all shipping cases. If you find any damage, call your transportation agent at once and have them make
a description on the freight or express bill describing the damage and the number of pieces. Then write us and we will send
you the original bill of lading. Get a claim blank from the express or truck company. Fill the claim form out. Attach the claim
blank to the original bill of lading together with a copy of our invoice. Attach a memo on which you show the value of the
damaged goods. Mail or hand these papers to your local transportation agent. They will process your claim with reasonable
promptness.
Please note, we cannot and will not enter claims for damages. If we filed claim here, it would be sent to your local freight
agent for verification and investigation. This time can be saved by your filing the claim directly. Every consignee is on the
ground floor and in contact with the local agent who inspects the damaged goods, and thus, each claim can be given individual
attention.
Since our goods are packed to comply with the regulations of all railroad, truck, and express companies, we cannot allow
deduction from any invoice because of any damage, however, be sure to file your claim promptly. Our goods are sold F.O.B.
factory. We take receipt from the transportation company certifying that the goods were delivered to them in good order, and
our responsibility ceases.
It is seldom that any breakage or damage occurs in any of our shipments, and in no case will the customer be out any expense
if they follow the above instructions.
Be sure to keep all damaged goods subject to examination of the truck or express company inspector, who may call on you
some time later. These damaged goods, of course, will belong to them, and they will inform you what to do with them. If you
dispose of these damaged goods, your claim may not be paid.

2. General Description and Specifications
Super Vac ventilators are specifically designed to provide a convenient and portable source of air. Super Vac positive pressure
ventilators are tested to AMCA PPV Standard 240-95, for use in extreme conditions.
This ventilator is designed for high powered air movement. Super Vac’s propeller produces a greater intake of air and
eliminates turbulence at the tips. Each blade is statically balanced for high efficiency and long life.
This document is designed to function as a quick start guide and not an in-depth comprehensive instructional manual. Please
read all accompanying documents shipped with your ventilator. Due to the many features of gasoline powered equipment
thorough familiarity with the engine operating controls is essential to assure safe and trouble free operation.

3. Product Safety Precautions
Ø Do not use the ventilator for purposes other than its’ intended use.
Ø Wear eye and ear protection when operating the ventilator.
Ø Never operate ventilator while fatigued.
Ø Do not disassemble or modify the ventilator in any way. Doing so may lead to mechanical failure or personal injury.
Ø Do not wear loose clothing that could become entangled in the operating ventilator.
Ø Never permit anyone to operate ventilator without proper instruction.
Ø Do not operate ventilator without proper inlet or outlet guards in place. If guards are missing or damaged, contact
factory for replacements.
Ø Do not place fingers or other foreign objects through inlet or outlet guards. Should a foreign object enter the ventilator,
immediately stop engine. Be certain all mechanical motion has stopped. Disconnect spark plug wire from spark plug and
keep it away from spark plug before removing foreign object.
Ø Do not use with any fuel supply source other than the provided fuel tank.
Ø Engine exhaust gas contains poisonous carbon monoxide. Avoid inhalation of exhaust gas. Never run the engine in a
closed or confined area.
Ø Do not place or operate ventilator on unsteady tables, slanted surfaces or other unstable surfaces.
Ø Never use this ventilator in any explosive environment.
Ø Do not use chock blocks to increase the angle of the ventilator, severe injury could occur.
4. Before Operating Ventilator
§ Engine is shipped without oil. With engine in a level position, remove oil fill plug and dipstick. Fill with 21 ounces of
the recommended oil. See page 1 of the TECUMSEH Operator’s Manual for oil viscosity recommendations and
capacity.
§ Always operate this ventilator with unleaded gasoline having a pump octane rating of 85 or higher.
§ A complete inspection of the ventilator should be made prior to operation.
§ Check all threaded fasteners for proper tightness.
§ Inspect inlet and outlet guards for damage or missing pieces. Replace damaged or missing guards before operating
ventilator.

5. Operation
Check ventilator inlet and outlet guards for obstructions.
Check and remove from immediate surrounding area any
objects that could be drawn into the ventilator intake.
Check the engine oil level, running the engine with a low oil
level can cause engine damage. See page 2 of the
TECUMSEH Operator’s Manual.
Check the engine air cleaner. A dirty filter will reduce
engine performance. See page 4 of the TECUMSEH
Operator’s Manual.
Check the fuel level. Do not overfill. Starting with no more
than a 3/4 full tank will help reduce operating interruptions
for refueling and avoid fuel spillage when engine is tilted.
See page 2 of the TECUMSEH Operator’s Manual.
Place ventilator in desired location before starting.
Refer to the TECUMSEH Operator’s Manual for additional
information showing locations of engine control features
and positions.
This engine is equipped with an Low Oil Shutdown which is
designed to prevent engine damage caused by an insufficient
amount of oil in the crankcase. Before the engine can fall below a safe limit, the Low Oil Shutdown will automatically stop the
engine (the engine speed control will remain in the current position). The Low Oil Shutdown is sensitive to the engine being
operated at an incline. Operate ventilator within the design limits of the engine tilt lever.

3. Move throttle control to the SLOW position.
4. Pull the starter grip lightly until resistance is felt, then pull briskly. Do not let the starter grip return by releasing grip,
this can lead to starter cord breakage. Return starter grip gently to the recoiled position.

6. Maintenance and Repair
Maintenance should only be performed by experienced and trained personnel.
Be sure the ventilator blade has come to a complete stop before performing any maintenance or repair.
Disconnect spark plug wire from spark plug and keep it away from spark plug.
The ventilator blade should be specially checked for build-up of material or dirt which may cause an imbalance. Excessive
imbalance can lead to accelerated wear on engine bearings and vibration. Remove ventilator guards. Clean blade and inside
housing with mild detergent and water. Do not use abrasives, sharp instruments or caustic solvents that may scratch or damage
the aluminum alloy blade..

§ Incorrect octane fuel, too low octane.
ENGINE WILL NOT START Possible Cause Correction
Check control positions Fuel valve OFF Move lever to ON
Choke is OFF Set choke to FULL on (Unless engine is warm.)
Throttle control is on STOP Move throttle control to SLOW.
Low Oil Shutdown Engine oil is low or engine is being operated on too
steep an incline.
Check fuel Out of fuel Refuel
Deteriorated fuel Drain fuel tank and carburetor. Refuel with fresh
gasoline.
Contamination in fuel tank
blocking fuel line
Drain fuel tank and carburetor. Refuel with fresh
gasoline.
Remove and inspect spark plug Spark plug faulty, fouled or
improperly gapped.
