STOPPING
ÀÀ BEFORE STOPPING (see Figure 1):
A. Run engine for a few minutes to help dry off any moisture
on engine.
B. To help avoid possible freeze-up of starter, proceed as
follows:
RECOIL STARTER:
With engine running, pull starter rope with a rapid continu-
ous full arm stroke three or four times.
NOTE: The unusual sound made by pulling starter rope
will not harm engine or starter.
ELECTRIC STARTER:
1. Connect power cord to switchbox, then to wall outlet.
2. With engine running, push starter button and spin starter
for several seconds.
NOTE: The unusual sound made by spinning starter
will not harm engine or starter.
3. Disconnect power cord from receptacle first, and then
from switchbox.
ÁÁ STOP ENGINE (see Figure 1):
A. Move equipment control (see equipment manufacturer’s
instructions), engine control lever or ignition switch (if so
equipped) to “STOP” or “OFF”.
B. Remove ignition key (if so equipped see Figure 2) from
carburetor cover.
DO NOT TURN IGNITION KEY.
ÂÂ AFTER ENGINE IS STOPPED (see Figure 1):
A. To help avoid possible freeze-up of engine controls,
proceed as follows:
1. Wipe all snow and moisture from engine in vicinity of
control lever and choke.
2. Move equipment control (see equipment manufactur-
er’s instructions) or engine control lever back and
forth several times and leave in the “STOP” or “OFF”
position.
3. Move engine choke back and forth several times and
leave in the “FULL” position.
B. Close fuel valve (see Figure 3).
C. DISCONNECT SPARK PLUG WIRE FROM SPARK
PLUG AND KEEP IT AWAY FROM SPARK PLUG.
D. TURN IGNITION SWITCH KEY (IF SO EQUIPPED) TO
“OFF” POSITION AND REMOVE KEY FROM SWITCH.
THIS WILL REDUCE THE POSSIBILITY OF UNAUTHO-
RIZED STARTING OF ENGINE WHILE EQUIPMENT IS
NOT IN USE.
NEVER STORE ENGINE WITH FUEL IN TANK IN-
DOORS OR IN ENCLOSED, POORLY VENTILATED
AREAS, WHERE FUEL FUMES MAY REACH AN OPEN
FLAME, SPARK OR PILOT LIGHT AS ON A FURNACE,
WATER HEATER, CLOTHES DRYER OR OTHER GAS
APPLIANCE.
