c. Cold Weather Engine Starting Procedures
A cold weather starting-aid kit
(Fig. 2)
is provided to assist in starting the engine at temperatures
below 50 degree F. To start the engine, using the starting aid, proceed as follows:
(1) Position switches and controls as instructed in steps (1) through (4), paragraph B, Normal
Engine Starting Procedures, above.
(2) Prepare starting aid for use. The starting aid is shipped in a safe condition and is not operable
until assembled. Assemble as follows:
Fires, fumes, and flying parts can kill or injure! Starting fluid is extremely
flammable. It is under pressure. Use caution when handling. Avoid contact with
skin and avoid breathing vapor.
a. Loosen clamp screws (1, Fig. 2) and slide the cylinder (2) upward sufficiently to remove
protective cap (3) and plug (4).
b. Use bottle opener to remove cylinder cap (3). Unscrew and remove plug (4).
c. Slide the cylinder (2) downward and thread into the valve (5). Tighten securely. The starting
aid is now ready to use.
(3) Cold weather starting procedures are exactly the same as for normal starting except:
a. Before cranking the engine, pull the starting aid control (24, Fig. 1)
OUT
to the full extent of
its travel. Hold for 2 to 3 seconds. (This allows the starting aid valve chamber to fill with
pressurized ethyl ether.)
b. Push the control
IN.
(This step sprays starting fluid into the engine intake manifold.)
c. Push starter switch (28) to crank engine.
d. Follow normal starting procedures and CAUTIONS above [steps (5) through (7), para. 2, B].
e. In extremely cold weather it may be necessary to repeat steps (a) and (b) above.
Use starting aid only for starting. Do not operate while engine is running.
Do not “flood” the engine with starting fluid. A serious explosion could result.
d. Preparation for Power Delivery (Normal Automatic Voltage Control)
The following are power delivery preparation procedures to be followed after the engine is started.
(1) Check and position switches and controls.
a. Loosen fastener (3, Fig. 1) and pull generator control tray outward. Place automatic-manual
switch (33) in
AUTOMATIC
position. Close tray and secure.
b. Loosen fastener (3) and pull protective relay tray outward. Place test bank switch (34) in
AIRCRAFT position if the aircraft being serviced is equipped with 28.5-V DC interlock relay
system. (If not, place in TEST BANK position.) Slide tray in and secure.
c. Meter switch (5) may be in any position except pointing straight DOWN.
(2)
Connect output cable plug connector to aircraft receptacle. Be sure connectors are mated fully
and securely.
