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.

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.

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..
