6.2 Deflection head and Extension pipe Replacement
The deflection head and extension pipe should be replaced when the head is 75% worn
away.
To remove these parts, unscrew the head holding nut and remove the head and extension
pipe.
By replacement make sure no abrasive or dirt particles get between the components.
Check worn-out heads for symmetrical wear before discarding them. Uneven wear means
either the flow of air / abrasive was not smooth or the tip was not properly aligned. Do not
use great force when tightening the head holding nut. Hand tightening is preferable.
6.3 Nozzle Replacement
The 12.5 mm nozzle should be replaced when the throat is worn to 16 mm I.D. As the
throat size increases, so do air and abrasive requirements. With a small compressor, it may
be necessary to replace sooner in order to maintain proper air pressure at the nozzle.
