Danger!
Maintenance and service works may only be implemented by competent personnel.
Disregarding this note can cause damage to the tank system and/or injuries to the per-
sonnel.
8.1 Maintenance intervals
Interval Activity
Daily Check the tank system for completeness
Check all mechanical and electrical connections for
tight fit.
Remove hot melt material residues and other incrus-
tations from the tank system.
Check the tank for impurities and foreign objects
(remove immediately as necessary).
For tank systems with spray-air adapter kits:
Drain the maintenance unit. Replace the dirty filter
as needed.
Every 500 operating hours Check the gear wheel pump for hot melt material
discharge.
Every 3 years Replace the battery of the realtime clock in the con-
trol unit (see Chap. 8.3).
8.2 Cleaning
Attention!
Do not use any aggressive solvent or combustible cleaning agents to clean the tank sys-
tem and its components. Such substances can cause damage to the tank system.
Using a suitable tool (e.g. cloth, soft brush, wood spatula), mechanically remove hot melt
material residue and other pollution, especially from the inside walls of the tank.
To clean the conveying route, carry out the following work steps:
Info
Before cleaning the conveying routes, have your hot melt material manufacturer inform
you about suitable cleaning agents. Observe the processing data sheet and the security
advice contained therein.
1. Make sure that only minor amounts of hot melt material residue is in the tank.
2. Fill the cleaning agent into the tank. Place a collection basin under the nozzle of the
manual application unit.
3. Activate the trigger of the manual application unit until the cleaning agent has com-
pletely run through.
4. Fill fresh hot melt material into the tank. Continue activating the trigger of the manual
application unit until only hot melt material (without any cleaning agents) is dis-
charged.
