III. Primer Bulb and Choke
In Temperatures above 40°F (5°C):
Follow instructions in Section B.I. See "I. Primer Bulb Only" instructions on page 10. See Table 4 on page 10.
In Temperatures below 40°F (5°C):
1.To avoid carbon monoxide poisoning, be sure engine is outdoors in a
2.Move engine throttle control to “CHOKE” or “START” position, if present (see equipment manufacturer’s instructions). See Figures 25, 26 and 27.
3.When starting a cold engine, push primer bulb firmly 3 times, allowing primer bulb to return completely to orig- inal position between pushes. See Figure 24 on page 11. Afterward, continue reading instructions below.
NOTES
Be sure to cover vent hole when pressing primer bulb. See Figure 24 on page 11. Afterward, continue reading instructions below.
Cooler temperatures may require pushing primer bulb firmly 5 times.
DO NOT use primer to restart a warm engine after a short shutdown. Doing so will flood the engine and may result in equipment malfunction.
4.Operate equipment control to release engine brake or clutch, if present (see equipment manufacturer’s instructions). See Figure 25.
When pulling starter rope, the rope
!WARNING
can unexpectedly jerk back toward engine causing serious injury. To avoid this risk, carefully follow these instructions:
5.Grasp starter cord handle. See Figure 25.
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 engine throttle control to “FAST” position.
b.Next, move engine throttle control to desired speed in “RUN” range.
NOTES
If engine starts but falters when engine throttle control is moved to “FAST” position:
a.Move engine throttle control back to “CHOKE” position. See Figures 25, 26 and 27.
b.Next, move engine throttle control to “FAST” position. See Figures 25, 26 and 27.
If engine dies after engine throttle control is moved to “FAST” position, repeat steps 2 thru 6 to restart engine.
