2 Tester3 Valve


Tools Required000 589 14 27 00 Tester

NoticeWhen testing the injection nozzle, do not place your hand intothe spray of a nozzle. The spray will penetrate deep into theskin and destroy the tissue.

1. Connect the fuel injection nozzle to the tester (2).

Tester 000 589 14 27 00

2. Close the valve (3) and pump 5 times strongly.

3. Chatter test :

Slowly operate the hand lever at tester (approx. 1 strokeper second). The nozzle must spray with a gentle chattering.

4. Spray pattern test :

Operate the hand lever at tester rapidly (approx. 2~3 strokesper second).

� Good

The spray pattern shows closed and well atomized.

� Poor
