that the manual is in error, or that the planes diverted to China were not
equipped the same as those sent to North Africa for the RAF.]
In case of battery failure, the started may be cranked by hand with crank
and extension provided for this purpose, both being located in rear access
compartment. The starter is operated by turning the crank handle which is
inserted in the spiral slot provided in the end of the crank extension, on
right hand side of engine cowl. Turn the crank with gradually increasing
speed until a fairly good rate of speed is obtained. Remove the crank
handle and extension. The engagement of the started will then be
accomplished by a pull on the hand starter button located immediately
above the crank. Caution: Starter crank and extension must be removed
immediately after cranking and before actuating starter pull.
17. Oil Dilution Control is located on the switch panel on the port side
of the cockpit.
(a) Before stopping the engine when a cold weather start is anticipated,
hold the oil dilution control switch "On" for approximately four minutes
at 800 RPM and stop the engine with the ignition switch, continuing to
hold the dilution control switch "On" until the engine stops. Then turn
the standard fuel cock to the off position.
(b) In starting the engine a normal start should be made. After starting
the engine, if a heavy viscous oil is indicated by oil pressure that is
too high or by oil pressure that fluctuates or falls back when the engine
RPM is increased, the dilution valve should be held "On" to dilute the oil
and correct this condition. Over dilution will result in a steady low oil
pressure and should be avoided if possible.
(c) If the engine heat is excessive when operating the oil dilution
control, the heat may evaporate the fuel out of the oil and leave the
normal high viscosity oil in the engine. When this condition is
encountered, the engine should first be shut off and allowed to cool for
fifteen minutes, then re-started and the instructions outlined in
paragraph "a" followed in preparing the engine for cold weather starting.
(d) Take-off may be made four minutes after starting the engine if there
has been enough rise in oil temperature (40°c. minimum), if the engine
holds its oil pressure and if the engine runs smoothly, or, the take-off
may be made as soon after four minutes as these conditions are obtained.
18. Hand Fuel Pump Control is located on the port side of the cockpit
forward of the throttle quadrant.
19. Radiator Flap Control is located on the starboard side of the cockpit
near the floor. It consists of a long lever and a rack. The latter is
provided with a stop at each end and may be set for "full open" (handle
fully down), "Full closed" (handle fully up), or any intermediate
position.
NOTE: Filling points for:
Wing fuel tanks through left hand wing fillet.
Fuselage fuel tanks through rear vision glass, left hand side, forward.
Oil tanks through rear vision glass, left hand side, aft.
Coolant tank through inspection door, top of engine cowl.
Operational Equipment
20. Gun Firing Switch - See Section 1, paragraph 1 [DF: should be para. 3]
21. Switches and Rheostats are located on panel on the left, below the
throttle quadrant. Care must be taken to insure that all rheostats are in
the extreme "Off" position when not in use, as they are equipped with
integral switches.
22. Oxygen - Two oxygen bottles are carried in supports in the aft part of
the fuselage, and accessible through the fuselage access door. The oxygen
regulator and bayonet outlet are located on the starboard side of the
