Lincoln Electric IM10074 BULLDOG 5500 - Manual (Page 18)

4. Pull the cord rapidly.
5. If the engine does not start, open the choke slight-
ly 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 sec-
onds to several minutes, depending on the tem-
perature. 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 equipment 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
ownerʼs manual.

BEFORE STARTING THE ENGINE
CHECK AND FILL THE ENGINE OIL LEVEL:
1. Place the machine on a level sur-
face.
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. Put the “ON/OFF” Switch in the
“ON”(I) 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.
