7 Care and maintenance

CAUTION
In order to prevent unintentional operation, disconnect
the tool from the compressed-air supply and remove
the mortar cartridge before cleaning the tool or before
carrying out maintenance.
7.1 Care and maintenance of the tool
CAUTION
Keep the appliance, especially its grip surfaces, clean
and free from oil and grease. Do not use cleaning
agents which contain silicone.
Apply a few drops of acid-free compressed-air oil to the
inside of the compressed-air connector each day.
Check the condition of the piston regularly and replace it
if found to be worn or damaged.

8 Troubleshooting

Fault
The cartridge can't be inserted
in the tool.
No mortar flows out of the mix-
ing nozzle.
Inadequate flow of mortar from
the mixing nozzle.
The cartridge cannot be re-
moved from the tool.
Mortar adhering to the tool must be cleaned off with a
cloth as quickly as possible before it hardens.
NOTE
Hardened mortar can be removed only by mechanical
means. Take care to ensure that the tool is not damaged
in the process.
Clean the outside of the tool at regular intervals with a
slightly damp cloth. Do not use a spray, steam pressure
cleaning equipment or running water for cleaning. Never
dip or soak the tool or its parts in solvents.
7.2 Checking the tool after care and maintenance
After cleaning or carrying out maintenance, check that
moving parts function faultlessly, that no parts are stick-
ing, broken or damaged and that the tool operates fault-
lessly.
Possible cause
The piston rods are not fully retracted.
The cartridge has been inserted incor-
rectly.
The compressed-air connection is
faulty.
The operating pressure is too low.
The mortar has hardened in the mix-
ing nozzle.
The cartridge is empty.
The mortar is too cold.
The operating pressure is too low.
Flow resistance is too high when a
mixing nozzle extension is used.
The piston rods are not fully retracted.
Remedy
Press the piston retraction button.
