PART III - HANDLING

                  of white smoke will be emitted.  Should this
                  occur, move the throttle to fully OFF, keep-
                  ing the starter engaged for about 30
                  seconds to clear the excess fuel.  Failure to
                  close the throttle to OFF will usually result
                  in a hot start.
       (iii)The start must be abandoned by pressing the button
            marked PUSH TO STOP STARTER should either of
            the conditions given below arise.  Failure to do so will
            inverter to cut in and the fuel flow amplifier to warm
            result in excessive temperatures when the light-up
            eventually takes place because of accumulation of fuel
            in the combustion chambers and jet pipe:-
            (a)  If no light-up has been obtained by the time the
                 r.p.m. have reached 10 per cent.
            (b)  If the rate of acceleration between 6 per cent. and
                 10 per cent. is unduly slow coupled with a failure
                 to ignite.  Should this fault be encountered the cause
                 must be rectified before a further start is attempted.
                 An r.p.m. of 10 per cent. and a light-up should be
                 obtained within 10 seconds of opening the throttle.
       (iv) Before attempting a second start, wait for three minutes
            to allow the accumulated fuel to drain and the starter to
            cool.  The starter is limited to three successive starts of
            one minute duration per start.  If more than three starts
            are required allow the starter to cool for 30 minutes
            before a further attempt is made.
       (v)  The starter will cut out automatically.  The PUSH TO
            STOP STARTER button must never be used for this
            purpose during a normal start, otherwise damage may
            occur and the rate of acceleration may be reduced.

       (vi) (a)  A start or acceleration during which the j.p.t.
                 exceeds 1,000°C. momentarily, or any ten starts or
            accelerations during which the j.p.t. exceeds 870°C.
            momentarily entails the engine removal and overhaul.
            (b)  When a hot start takes place, stop the engine imme-
                 diately by closing the throttle to the OFF position.
                 If smoking or a fire occurs and persists, engage the
                 starter for 20-30 seconds, keeping the throttle OFF,
                 to blow out the excess fuel.
            (c)  Five starts or accelerations during which 870°C. is
                 exceeded momentarily requires that the engine be
                 examined for possible damage prior to flight.
            (d)  The duration of the excessive temperature and the
                 temperature obtained must be entered in the F.700
                 for the aircraft.
