INSTRUCTIONS FOR THE ADJUSTMENT OF THE OSCILLATING JACK
Adjustment of 1st flame air damper position
1) To increase air supply capacity, turn ring nut C1 anticlockwise;
use counter wrench on body A of the jack to prevent too much
being exerted on eyelet H's pin. This action lowers body A and
favours the opening of air damper F in first stage.
To reduce the flow of air turn ring nut C2 clockwise, also in
this case use the counter wrench on the body of the jack. In
this case body A is raised and favours the closing of the air
damper F.
2) After adjustment of the 1st flame air, lock the two ring nuts C1
and C2.
Adjustment of 2nd flame air damper position
1) Slacken the locking nut E.
2) To increase 2nd flame air flow, slacken screw D; in this way
the travel distance of the hydraulic piston will be lengthened.
To reduce air flow tighten the screw.
2) After 2nd flame air flow adjustment, tighten nut E.
N.B. To avoid damaging eyelet H, carry out all the adjustment ope-
rations with use of wrench and counter wrench.
