Stopping The Engine; Break-In Period - Lincoln Electric POWER-ARC SVM103-C Service Manual

B-7
4. Pull the cord rapidly.
5. If the engine does not start, open the choke
slightly (move lever upward) and pull the starter
cord rapidly again.
When the engine starts, gradually open the choke
to the "RUN" position. To open the choke fully,
requires an engine warm-up period of several
seconds to several minutes depending on the
temprature. After starting the engine, first open
the choke (toward RUN) until the engine just
begins to run smoothly. Then open the choke in
small steps, allowing the engine to accept small
changes in speed and load, until the choke is fully
open (in RUN). During engine warm-up the
equiptment can be operated.
FOR A "HOT" ENGINE:
1. Open the fuel shutoff valve on the bottom of the
fuel tank.
2. Place the choke lever in the highest,
upward position. Closing the choke
of a hot engine will flood the carbure-
tor and prevent starting.
3. Pull slightly on the recoil starter handle until resis-
tance is felt.
4. Pull the cord rapidly.
FOR BEST ENGINE STARTING:
• Always use fresh gasoline and be sure the filter is
clean and properly maintained.
• If you use an alternate fuel tank or supply, be sure
to install an in-line fuel filter.
• Do not pull the recoil starter with the
choke in the downward position more
than one time. Repeated pulls on a
choked engine will flood the carburetor.
• If the engine will not start, see the TROU-
BLESHOOTING section of this manual.
OPERATION

STOPPING THE ENGINE

1. Remove all welding and generator power loads
and let the engine cool by running it for several
minutes.
2. Stop the engine by turning the Rotary Stop
Switch on top of the engine to the "OFF" position.
3. Hold the lever down firmly until the engine com-
pletely stops. Otherwise, the engine may restart
or sputter as it stops.
4. Close the fuel shutoff valve at the bottom of the
fuel tank.
Close the fuel valve when the machine is trans-
ported to prevent fuel leakage from the carbure-
tor. Drain the tank before transporting the
machine in a vehicle.
For long periods of storage, turn off the fuel shut-
off valve (lowest, downward position) and let the
engine run until there is no more fuel in the line.
Use a fuel additive such as Sta-Bil to minimize fuel
gum deposits.
RUNNING THE ENGINE
The engine is set at the factory to run at high idle
speed when not under load. You should not adjust
this setting yourself.

BREAK-IN PERIOD

The engine will use a greater amount of oil during its
"break-in" period. The break-in is about 12 running
hours.
Check the oil frequently during break-in. Change the
oil after the first 5 hours of operation. For more
details, see the MAINTENANCE section of the engine
owner's manual.
During break-in, subject the POWER-ARC 4000 to
only moderate loads. Avoid long periods running
at idle. Before stopping the engine, remove all
loads and allow the engine to cool several min-
utes.
