OPERATION

BEFORE STARTING THE ENGINE

CHECK AND FILL THE ENGINE OIL LEVEL:

1. Place the machine on a level
surface.
2. Open the oil fill plug.
3. Fill (if necessary) until oil flows out the top of the
fill plug hole.
4. Replace the fill plug and tighten securely.

CHECK AND FILL THE ENGINE FUEL TANK:

1. Remove the fuel tank cap.
2. Fill the tank to allow approximately
1/4 inch (5 mm) of tank space for fuel
expansion. DO NOT FILL THE TANK
TO THE POINT OF OVERFLOW.
3. Replace the fuel tank cap and tighten securely.
NOTE: The engine will operate satisfactorily on any
gasoline meant for automotive use. A mini-
mum of 87 octane is recommended. DO NOT
MIX OIL WITH THE GASOLINE.
Use clean, fresh, lead-free gasoline. Leaded gasoline
may be used if lead-free is not available. However,
lead-free gasoline leaves fewer combustion deposits
and gives longer valve life. Purchase gasoline in
quantities that will be used within 30 days, to assure
freshness.
NOTE: We DO NOT recommend using gasoline that
contains alcohol, such as gasohol. However,
if gasoline with alcohol is used, it MUST NOT
contain more than 10% Ethanol and MUST
be removed from the engine during storage.
DO NOT use gasoline containing Methanol.
STARTING THE ENGINE
NOTE: Remove all loads connected to the AC power
receptacles before starting the gasoline
engine. Turn the Rotary Stop Switch to the
"ON" position.
FOR A "COLD" ENGINE:
1. Open the fuel shutoff valve.
2. Place the choke lever in the "CHOKE"
position.
3. Pull slightly on the recoil starter handle until resis-
tance is felt.
