COLD WEATHER OPERATION.
Prior to starting on cold mornings, it is advisable to pull the pro -
peller through several times by hand to "break loose" or "limber" the
oil, thus conserving battery energy. In extremely cold (0°F and lower)
weather the use of an external preheater is recommended whenever
possible to reduce wear and abuse to the engine and the electrical system.
Cold weather starting procedures are as follows:
With Preheat:
(1) With ignition switch "OFF" and throttle closed, prime the
engine four to ten strokes as the propeller is being turned over
by hand.
NOTE
Use heavy strokes of primer for best atomization of fuel.
After priming, push primer all the way in and turn to locked
position to avoid possibility of engine drawing fuel through
the primer.
(2) Clear propeller.
(3)
Pull master switch "ON."
(4) Turn ignition switch to "BOTH."
(5) Open throttle 1/ 4" and engage starter.
Without Preheat:
2-12
(1) Prime the engine eight to ten strokes while the propeller
is being turned by hand with throttle closed. Leave primer
charged and ready for stroke.
(2) Clear propeller.
(3)
Pull master switch "ON. "
(4) Turn ignition switch to "BOTH. "
(5)
Pump throttle rapidly to full open twice. Return to 1/4"
open position.
(6) Engage starter and continue to prime engine until it is run­
ning smoothly, or alternately, pump throttle rapidly over first
1/ 4 of total travel.
(7)
Pull carburetor air heat knob full on after engine has started.
Leave on until engine is running smoothly.
(8) Lock primer.
