2General Information
Telescopic multifunction gun
The multifunction gun is a device operated with compressed air for processing me-
diums for general applications from 310 ml cartridges. Mediums for laying seams
and spray mediums can be processed. It is intended for operation in industrial com-
panies and workshops.
The cartridge to be processed is inserted in the cartridge pipe, fixed with the car-
tridge nut and pressed out with the help of the telescopic piston driven by com-
pressed air. A cartridge nut and processing nozzle is to be chosen depending on the
type of processing (seam laying of surface coating). The components for com-
pressed air supply are found in the gun handle. The pressure reducing valve re-
duces the input pressure to the optimal pressure for processing sprayable sealing
masses. With the compressed air control valve, the material flow and spray air can
be progressively regulated. The two-stage discharge valve guarantees the neces-
sary sequence of air supply when starting and stopping for the spray operation.

3Commissioning
The plug with seal, included loose with the delivery, must be screwed into the gun
handle before initialisation. The plug fits the most common quick compressed air
couplings DN 7.2.
Instead of the plug, a hose mandrel for mounting the on-site compressed air hose
with NW 6 can be mounted (see accessories).
4Operation
Before loosening the cartridge nut, the gun is to be disconnected from the
compressed air supply.
Do not point at people!
Wear protective gloves and goggles!
The cartridge is to be prepared in line with the manufacturer's instructions depend-
ing on the cartridge type and the material to be processed.
The two-part nozzles required for processing are included in the gun scope of sup-
ply and can be reordered using the item numbers listed in the "Accessories" chap-
ter. The nozzles included with the cartridges can also be used if the cartridge nuts
fit this gun. The cartridge manufacturer's mounting instructions must be observed.
Use undamaged cartridges only!
Use clean and unused nozzles only!
Use fresh material only!
The instructions of the cartridge manufacturer concerning processing and
storing must be observed.
Procedure:
-Pierce the base cover of aluminium cartridges with a suitable tool and remove the
anti-condensation material found inside.
-Cut-off the cartridge tip or pierce with a suitable tool
-Screw a material nozzle (inner nozzle) onto the cartridge
-Insert the cartridge in the cartridge pipe. The telescopic piston must be pressed
back with the cartridge into the start position.
-Screw the air nozzle (outer nozzle) in the blue cartridge nut up to the impact
point.
-Screw the cartridge nut tightly onto the cartridge pipe.
The thread on the nut and on the cartridge pipe must be free of dirt.
Check the tight fit of the cartridge nut before each application.

The gun can be connected to all usual compressed air
mains with a pressure up to 10 bar.
The setting screws for setting the working pressure are found on the handle:
blue setting screw - spray air
red setting screw - press-out air (press-out speed)
The following applies to both setting screws:
Turn left pressure increase
Turn right pressure reduction
Before beginning processing, the setting screws must be set regarding the medium
to be processed and the coating work to be performed. A test should be carried out
on a suitable surface.
By pressing the trigger, a compressed air cushion is generated behind the tele-
scopic piston and the cartridge is pressed out.
The internal working pressure is exclusively controlled by the adjustment of the
setting screws and cannot be influenced by the position of the trigger.
The gun is vented by releasing the trigger - the medium flow stops and a hissing
noise is produced.
Guide the nozzle at a distance of approx. 4 cm at a
right angle and vertical to the seam. Pull evenly. If the
nozzle is aligned at an angle, there is edge spreading
and an uneven spray pattern on the seam.

Guide the nozzle at a distance of approx. 20 cm vertical
to the surface.
By adjusting the spray air amount and material feed, an
adapted spray pattern can be set for the application
case:
-A limited material flow gives finer structures
-Limited spray air volume and limited material flow
gives narrower spray areas
The setting should be checked with spray tests.
Fully close the spray air controller (blue setting
screw), place the nozzle on the surface at an angle
and pull evenly.
Never close the nozzle by placing it flat.
In this case, the medium can enter the gun through
the inner and outer nozzle and damage it.
Media exclusively suitable for seam laying should be processed with single nozzles
as intended. These are included in the cartridge scope of supply.
The cartridge is to be prepared in line with the manufacturer's instructions depend-
ing on the cartridge type and the material to be processed:
Use undamaged cartridges only!
Use clean and unused nozzles only!
Use fresh material only!
The instructions of the cartridge manufacturer concerning processing and
storing must be observed.
Procedure:
-Pierce the base cover of aluminium cartridges with a suitable tool and remove the
anti-condensation material found inside.
-Cut-off the cartridge tip or pierce with a suitable tool
-Screw a processing nozzle (included in the cartridge delivery) onto the cartridge.
-Cut-off the tip of the nozzle for the required seam width.
-Preheat the cartridge according to the manufacturer's instructions

-Insert the cartridge in the cartridge pipe. The telescopic
piston must be pressed back with the cartridge into the start position.
-Screw the black cartridge nut tightly onto the cartridge pipe.
The thread on the nut and on the cartridge pipe must be free of dirt.
Check the tight fit of the cartridge nut before each application.
Control of the compressed air supply takes place with the help of setting screws on
the handle as described in chapter 4.2.2.
Fully close the spray air supply (blue setting screw). The working speed can be con-
trolled depending on the material toughness with the red setting screw.
Place the nozzle at an angle on the surface and press the discharge. The infor-
mation described in chapter 4.2.3 should be considered
5What to do if...
... the medium is not sprayed although the spray air controller is fully opened?
–The two-part nozzle is not correctly mounted
remount the cartridge nut as described in chapter 4.2.1 and replace the noz-
zle if necessary
–The spray air channel in the cartridge pipe is dirty/blocked
clean and replace the pipe if necessary
... the pressing speed is too low?
–The compressed air valve (red setting screw) is set incorrectly
Adjust setting
–The input pressure is too low check the mains pressure
–The screen in the compressed air connection is blocked clean
–The medium is not suitable for processing with the maximum pressure (e.g. high
viscosity medium, 2 component cartridges)
preheat the cartridge according to the manufacturer's instructions if neces-
sary
... air escapes out of the gun while processing?
–A leak means that the working pressure in the gun drops
Check the seal on the compressed air connection and tighten the plug if nec-
essary
Service the gun
