Quick Adjustment using Hand Wheel
When changing from doubles or singles the spring will need to be adjusted.
The machine is supplied with two locking collars for the convenience of being able
to pre-set the desired tensions for quick and easy change over from singles to dou-
bles.
Initial setup:
Set the ideal spring tension for each type of target during initial setup, firstly set
the quick adjustment handwheel towards the single locking collar (one groove)
then proceed to adjust the spring tension using the regular spring adjustment nut
until the trap is throwing the correct distance with single clays. If necessary adjust
the locking collar up until it sits just behind the trunnion nut (where the thread
passes through the tensioner arm) this gives a quick reference to the correct posi-
tion for singles. Do not tighten the grub screw yet.
Next adjust the spring tension using the handwheel until it is correct for doubles,
adjust the double locking collar (two grooves) up until it sits the other side of the
trunnion nut , this gives a quick reference to the correct position for doubles.
It will now be possible to move easily between singles and doubles by turning the
handwheel until the stops are reached.
Double check that the spring tension is still as desired for each type of target, then
lock off each locking collar using the grub screw. Re tighten the locking nut on the
inside of the spring to prevent unwanted spring movement in use.
In daily use (Quick adjust):
With the Ideal spring tensions for singles
and doubles now pre-set, the trap can be
quickly adjusted using the hand wheel up
to the appropriate stop.
Increase tension
Turn hand wheel anti-clockwise.
Decrease tension
Turn the hand wheel clockwise
