Adjustment: Plunger Mechanism
As the arm rotates, the plunger presses gently
on the outer rim of the remaining clay stack to
hold it as the boom clay is released from the
iris plates. With the trap at rest and the clays
pushed towards the two rear hopper rods there
should be a visible gap between the second clay
up in the stack and the red polyurethane plung-
er p.
The plunger gap should be around 2mm (1/16")
and can be adjusted if required using two 10mm
spanners/wrenches. Holding the half nut
(located against the back of the brass plunger)
adjust the rear locking nut clockwise to increase
the gap or an-clockwise to decrease it.
Adjustment: Elevaon
Seng Elevaon angle
Trajectory of clays are from
approximately 26 - 50 degrees.
Loosen handwheel nut as shown,
lt to desired angle, re-ghten
handwheel .
ALWAYS disarm the machine before carrying out loading, adjustment or
maintenance.
Be aware that if machine is already lted upwards, when the hand-
wheel is subsequently undone the machine will jolt forward. Support
the weight of the machine from the top of the clay hopper when ad-
jusng the elevaon angle.
