4.5 Tension Adjustment of Rollers
It may be necessary from time to time to adjust the tension of the Roller Guides.
Correct wire tension is the minimum tension required to satisfactorily feed the wire through the
pistol.
The need to suddenly apply more tension is usually an indication of another issue such as
worn wire guides, incorrectly assembled spray head, excessive drag from the wire dispenser,
dirty/worn rollers or worn/damaged/seized pinch roll bearings.
To adjust tension, locate the Tension Screw which can be found on the top of the Pistol, in the
slot in front of the Pinch Release Cam. Using an appropriate Hex Key, turn the Tension
Screw:
CLOCKWISE – to increase the tension.
ANTI-CLOCKWISE – to decrease the tension.
NB: These issues should be addressed rather than increasing the tension which can
create other problems.
For example, excessive tension can deform the wire and make it out of round. This
will cause problems feeding the wire through the Spray Head. Too much tension will
also create heavy marks in the wire and create a lot of debris in the form of wire
shavings in the roller area.
Tension should be reduced to the minimum required to satisfactorily feed the wire.
NB: Take care not to over tension the Roller Guides. Especially when using softer wires.
