Contracor 10112630 [12/36] Deflection head and extension pipe replacement

CONTRACOR

Version 7.1

6.2 Deection head and Extension pipe Replacement

The deection 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 ow 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.
