                           PART 1II-HANDLING

    (b)  Starting

         NOTE.-1.   The engines may be started on the aircraft
                    batteries.  This, however, imposes an un-
                    desirable load on them and is not recom-
                    mended.  An external battery should normnally
                    be used for starting.

               2.   If an engine fails to start after two attempts, the
                    cause should be investigated before making
                    further attempts.

    (b)  Press the starter pushbutton of the selected engine and
         release after two seconds.

    (b)  When the undercarriage lights dim, move the H.P. cock to
         the half-open position.  When r.p.m. increase the cock
         should be moved slowly to the fully-open position.  The
         engine should accelerate to idling speed with the throttle
         closed.  The exhaust temperature may momentarily exceed
         the idling limit but it should settle down to no more than
         500°C.  The throttle must not be opened before the idling
         r.p.m. are attained.
         
    (e)  If the H.P. cock is moved too quickly from the half to the
         fully-open position, resonance and overheating may occur.
         If excessive exhaust temperatures and resonance persist,
         close the H.P. cock to stop the engine.  Excess fuel must
         have drained off before another start is attempted.
         
    (f)  If an engine fails to light-up, proceeed as follows:-

         (i)  Turn off the H.P. cock.
        (ii)  Have the appropriate isolating switches set off.
       (iii)  Ensure that the impeller has stopped turning.  Wait
              until the fuel has stopped draining from the nacelle
              and then dry out the engine by carrying out the start-
              ing cycle with the H.P. cock in the off position.
        (iv)  When the impeller has again stopped turning, have
              the ground crew remove any surplus fuel from the jet
              pipe.
         (v)  Have the isolating switches set on.
         
        (vi)  Start the engine as in sub-paras (b) to (d) above.
