2. (EN) Installation
2.1. Mobile units
Remove the protective packing from the pump, including plugs from the air inlet and the fluid outlet.
Remove the drum adapter from the pump tube. Mount the adapter into the 2" hole in the pump or pump bracket. If the pump
is to be used with a drum of similar the suction tube, 122 62 94, has to be fitted. Do not use Teflon tape to seal any thread.
Use Loctite sealant liquid for tubing system.
Put the pump vertically into the drum and lock the pump so that the outlet is in the desired position. Set the pump 10-15mm
clear of the bottom of the drum and lock the pump into place using the adapter.
Connect the liquid outlet hose to the outlet of the pump and the air coupler to the air inlet.
IMPORTANT! If the air pressure in the system is higher than the working pressure of the pump it will be necessary to
install an air regulator and gauge into the airline prior to the pump.
The pump is pre-lubricated with silicon grease. It is not necessary to use a lubricator during normal operation.
IMPORTANT! If a lubricator has been used with the pump, the pre-lubricated silicon grease will have been washed away. It
is therefore needed to continue the use of lubricator.

2.2. Fixed installations

Besides the above mentioned, please also note the following:
Do not mount a pump directly onto a sheet metal wall or similar construction, which can create noise resonance and augment
the normal noise level of the pump.
A hose must be mounted between the outlet of the pump and the fixed pipe work. This hose should have sufficient length to
make it possible to lift the pump in and out of the drum or tank without difficulty.
Do not let the pump run fast when starting up a new system or after changing barrel in an existing system. Start the pump
with lowered air pressure on initial priming and gradually increase the pressure as the system is primed.
3. (EN) Maintenance
Empty and clean the air filter.
If a lubricator is installed it should always be filled with air tool oil or similar. Mineral based motor oil, SAE 10, can also be
used, Synthetic oil or other oils must not be used.
Check for possible leakage in the connections or couplers.
Keep the fluid and equipment clean and free from dirt. When changing drum, make sure the pump tube and bottom valve are
kept off the floor.
4. (EN) Service
Avoid damage to packings and all moving surfaces. When servicing the pump, all parts should be protected from dirt,
especially the cylinder and central bar. Keep the working area and tools clean.
Clean and grease all surfaces with silicon grease or similar, especially all O-rings and moving surfaces.
Use kerosene or similar liquid for cleaning the air motor parts.
4.1. Air motor
Fasten the outlet housing of the pump into a vice in a vertical position. Loosen the four screws in the lid. Remove the lid. Air
supply nipple (Pos 2) is sealed by two O-rings in the valve mechanism.
To inspect the air filter u carefully thread a screw, M6 or W¼", between ½ and 1 turn inside the filter. Pull up and clean or
change it.
Loosen the silencer's (Pos 25) four screws (Pos 28) and remove the protective cover (Pos27). Unscrew the six screws
(Pos26), which keep the mechanism (Pos 1) in place. It is now possible to inspect and replace the valve mechanism or replace
the valve spool kit (Pos 24).
To inspect the air motor cylinder, loosen the four lower screws (Pos 29). Pull the air motor off the piston. Change all
damaged and worn parts and Reassemble in reverse order.
IMPORTANT! Lubricate all parts and seals in the air motor before reassembly with Silicone grease. No other grease should
be used.
