OPERATION

CAUTION: Read this complete OPERATION section and the section on SAFETY

PRECAUTIONS before starting the machine for the first time.

PREPARING THE ENGINE FOR OPERATION

1. When operating this machine for the first time, place the machine in an

uncongested and well ventilated work area away from flammable materials.

Place the machine on a concrete pad or a stable workbench.

2. Remove Gasoline Tank Cap and fill the Gasoline Tank with either regular or

unleaded gasoline of at least 87 octane rating. Lower grade gasoline (less than

87 octane) can cause poor performance when used in ANY combustion engine.

IMPORTANT

Gasoline with a minimum of 87 octane should be used. Use clean gasoline. Dirty

gasoline can promptly overload the fuel filter and “varnish” the moving parts of

the carburetor causing them to stick. Water in the gasoline can cause

unexplained stops. Very old or stale gasoline has a detrimental effect on the

rubber seals in the fuel system and causes hard starting because it vaporizes

poorly.

3. Replace the Gasoline Tank Cap on the Gasoline Tank and turn the cap firmly

in the clockwise (CW) direction until the stop is reached.

4. Wipe any spilled gasoline from the machine and allow time for any unseen

spills to evaporate.

CAUTION

Do not put any formulation in the machine until you have become familiar with

starting and stopping the pulse jet engine.
