COLD WEATHER OPERATIONS
Prior to starting with temperatures below freezing, it is advisable to pull the propeller through
several times by hand to "break loose" or "limber" the oil, thus conserving battery energy.
Note
When pulling the propeller through by hand, treat it as if the ignition switch is
turned on. A loose or broken ground wire on either ignition could cause the
engine to fire
In particularly cold weather (-18 ° C and below) it is recommended to use an external
preheater if possible to reduce engine wear and avoid overloading the electrical system.
Cold weather starting procedures are as follows.
1)
Electrical fuel pump...................... On (Pump audible)
2)
Throttle control ............................. Drawn
3)
Choke .......................................... Drawn
4)
Propeller are ................................ Clear
5)
Main switch .................................. On
6)
El. fuel pump ................................ Off
7)
Ignition switch .............................. Start
8)
Oil pressure ................................. Check

Important note
Fuel accumulations in the intake manifold can cause a fire hazard in the event of a
misfire. If this happens, continue cranking with the starter to draw the flames into
the engine. When starting in cold weather without preheating, it is always advisable
to have a helper standing by with a fire extinguisher outside the aircraft
Even at very low outdoor temperatures, there must be an indication on the oil temperature
gauge before Takeoff. After a reasonable warm-up period (2 to 5 min at 1000 rpm), the engine
must be accelerated several times to higher speeds. If the engine accelerates evenly and the
oil pressure remains normal and constant, the aircraft is ready to take off.
When operating in temperatures below -18 ° C partial use of carburetor heating must be
avoided. Partial preheating could increase the carburetor air temperature to a range between 0
° C and 21 ° C, where there is a high risk of icing under certain atmospheric conditions.
