A. Engine With Remote Control
1. To avoid carbon monoxide poisoning, be sure engine is
outdoors in a well-ventilated area.
2. Move switch to “ON” position. See Figure 6 on page 5.
Afterward, continue reading instructions below.
3. Move choke control on engine to “FULL CHOKE”
position. See Figures 11 and 12.
4. When starting a cold engine, push primer bulb firmly
with your thumb 3 times, allowing primer bulb to return
completely to original position between pushes. See
Figure 13 on page 7. Afterward, continue reading
instructions below.
NOTES
Cooler temperatures may require pushing primer bulb firmly
with your thumb 5 times.
Some engines are equipped with a remote throttle control.
See Figure 10.
DO NOT use choke or primer bulb to restart a warm engine
after a short shutdown. Doing so will flood the engine and
may result in equipment malfunction. See Figure 13 on
page 7. Afterward, continue reading instructions below.
When pulling starter rope, the rope
can unexpectedly jerk back toward
engine causing serious injury. To avoid this risk, carefully
follow these instructions:
5. Grasp starter cord handle. See Figure 14 on page 7.
Afterward, continue reading instructions below.
a. Pull rope out slowly until you feel drag.
b. Without allowing the rope to retract, continue pulling
rope with one rapid full arm stroke.
c. Return rope slowly to original position.
NOTE
Following the instructions listed in the steps above avoids
potential damage to the recoil mechanism.
6. When engine starts:
a. Move choke control to “1/2 CHOKE” position until
engine runs smoothly.
b. Next, move choke control to “NO CHOKE” position.
c. Move throttle control to desired speed in “RUN”
range. See Figures 9 and 10.
NOTES
If engine starts but falters when choke control is moved to
“NO CHOKE” position:
a. Momentarily move choke control back to “FULL
CHOKE” position.
b. Next, move choke control to “1/2 CHOKE” position
until engine runs smoothly.
c. Finally, move choke control to “NO CHOKE”
position.
If engine dies after choke control is moved to “NO CHOKE”
position, repeat steps 2 thru 6 to restart engine.
