Corrections
• Check the power voltage.
• Switch power switch to position I (ON).
• Check/replace fuse.
• Replace power cord.
• Henkel Service.
• Check depressurizing valve 10 and
pneumatic supply.
• Replace gauge.
• Replace regulator.
• When the controller is operational, the

dispensing needle.
• Replace dispensing needle.
• Check the dispensing valve (see
instruction manual for dispensing
valve).
• Check product reservoir.
• Refill product reservoir (see
Section 5.2).
• Increase the supply pressure (min
0.5 bar above reservoir pressure).
• Refill product reservoir (see
section 5.2).
• Connect product hose correctly.
• Check the dispensing valve (see
instruction manual for dispensing
valve).
• Lower pressure, longer dispensing
time.
• Tighten the reservoir knob.
