INTRODUCTION

Following normal use of the BETAGUN spray gun, it is necessary to check the moving parts at the top of the

spray gun for any signs of wear.

A kit of replacement parts is available from SODICAM under Part Number 77 11 171 459.

This technical note outlines the procedure for replacing worn parts of the spray gun nozzle.

FAULT-FINDING

When closing the cover (A) a metal fork moves and connects the spray gun drive bush to the mixer system (B)

for the two twin cartridges.

The chafing caused by rotation of the drive bush causes the progressive destruction of the fork. Normal

operating clearance is taking place between these two components.

This wear can be seen by :

Opening the spray gun nozzle cap and sliding the drive bush to visualise the degree of fork wear. If the

fork thickness has been considerably reduced (play ≥ 1 mm), replace these parts using the kit

mentioned above.

Fit the twin cartridges and close the spray gun nozzle cap.

Look through the aperture in the cover (A) to see whether the drive bush drive pins are engaged in the

mixer cartridges (B) along their entire length. If the pins are coming out or even half engaged, replace

these parts using the kit mentioned above.
