OPERATION
B-6
4. Pull the cord rapidly.
5. If the engine does not start, open the choke
slightly 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
temperature. 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 equip-
ment can be operated.
FOR A “HOT” ENGINE:
1. Open the fuel shutoff valve.
2. Place the choke lever in the “RUN”
position. Closing the choke of a hot
engine will flood the carburetor 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 “CHOKE” 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 or the engine
owner’s manual.
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 placing the ignition switch in
the “OFF” position.
3. Close the fuel shutoff valve.
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. Check the oil frequently during
break-in. For more details, see the MAINTENANCE
section in 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.
