ENGINE OPERATION

WARNING
DO NOT RUN THE ENGINE AT EXCESSIVE
SPEEDS. The maximum allowable high idle speed for
the Classic I is 1550 RPM, no load. Do NOT increase
the idle speed on the engine. Severe personal injury
and damage to the machine can result if it is operated
at speeds above the maximum rated speed.
Read and understand all safety instructions included in
the Continental engine instruction manual that is
shipped with your Classic I.

BEFORE STARTING THE ENGINE

Check and fill the engine oil level:
1. Be sure the machine is on a level
surface.
2. Remove the engine oil dipstick and wipe it with a
clean cloth. Reinsert the dipstick and check the
level on the dipstick.
Maintenance section of this manual.
3. Add oil (if necessary) to bring the level up to the full
mark. Do not overfill.
4. Replace the dipstick.
OPERATION
See Figure D.1 in the
CLASSIC I
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.
WARNING
Do not add fuel near an open flame,
welding arc or when the engine is run-
ning. Stop the engine and allow it to
cool before refueling to prevent spilled
fuel from vaporizing on contact with
hot engine parts and igniting. Do not
spill fuel when filling tank. If fuel is spilled, wipe it up
and do not start engine until fumes have been elimi-
nated.
NOTE: USE GASOLINE ONLY. Purchase gasoline in
quantities that will be used within 30 days, to assure
freshness.

STARTING THE ENGINE

NOTE: Remove all loads connected to the DC power
receptacle before starting the engine. Make sure the
fuel valve on the sediment bowl is in the open position.
1. Place the IDLER switch in the "HIGH" position and
the IGNITION switch in the ON position. Pull out
the choke cable and then press the START button.
NOTE: If the engine fails to start in 60 seconds, wait 30
seconds before repeating Step 1.
2. When the engine starts running, observe the oil
pressure. If no pressure shows within 30 seconds,
stop the engine and consult the engine operating
manual.
3. As the engine warms, slowly return the choke con-
trol to the in (off) position.
4. Allow the engine to run at high idle speed for sev-
eral minutes to warm up before welding. Cold
engines tend to run at a speed too slow to supply
the voltage required for proper idler operation.
