Maintenance

WARNING:

Allow only qualified personnel to perform the following tasks.

Observe and follow the safety instructions in this document and all other
related documentation.

NOTE:

Maintenance is an important preventive measure to maintain

operating safety and to extend the service life of the unit. It should not be
neglected under any circumstances.

Relieving Pressure

WARNING:

System and material pressurized. Relieve system pressure

before disconnecting heated hoses. Failure to observe can result in serious
burns.

WARNING:

Hot! Risk of burns. Wear heat‐protective gloves.

1. Set motor speed of the unit feeding the material to 0 min

‐1

; switch off

motor(s).

2. Place a container under the nozzle(s) of the applicator.

3. Activate the solenoid valves electrically or manually. Repeat this

procedure until no more material flows out.

4. Properly dispose of material according to local regulations.
