Closed water circuit
Closed water circuit Water tank with at least 20 l of water as it comes from the house pipe should be positioned above the high-pressure cleaner so that a gradient makes it easier for the high-pressure cleaner to suck in water... 1 is the inlet to the high-pressure cleaner
2 is the pressure hose to the control block
3 Pressure hose to the cylinder for supply and suction
3 Return from the control valve to the water tank
Water and frost? No problem
The press is insensitive to frost - only the high-pressure cleaner should be emptied in frost.
Maintenance
The press and the high-pressure cleaner require no maintenance. This applies to the metal parts. O-rings are made of NBR plastic and the piston seal is made of PUR plastic. Both plastics break down over time. Can take well over 10 years. The main enemy of these seals is the ozone in the air and sunlight. This must be taken into account when storing them. . If the control block loses a little water over time, it is enough to tighten the two screws a little. But not so far that the spring no longer has the power to move the plunger back. If that no longer helps, then the seal must be replaced. This is easy to do if you remove the circlip, assemble everything as usual and then attach the circlip. This is the only way to press the leather ring into the hole with excess.
Some plastics have an expiration date
.This is particularly true for soft, elastic plastics. The elasticity is achieved through plasticizers, and these evaporate over time. Less so in wet environments... because water is also a plasticizer... So even if the press is used little - a knife maker will not use it in continuous operation every day - the seals will need to be replaced after many years. 1 is the O-ring on the cover at the end of the cylinder. 2 In the wooden box there are O-rings for the pressure hose and snap rings for the control valve. 3 are O-rings for the M 16 screw that connects the piston to the thrust part. 4 Seals for the piston 5 Leather seals for the control block
Assembling the press with assembly aid
Assembling the press with assembly aid The picture on the left shows the piston with the push tube and the cover of the tube at the top. The M 16 thread at the bottom is used to hold the tube in place with a screw when you screw the piston onto the push part. The picture on the left shows the push unit being sunk into the tube. The M 16 screw has a small M 6 thread for screwing on the hook. The hook is included
.. Keep the piston at the same height.
Inserting the lower guide ring of the thrust unit
The left picture shows the lower guide part in front of the pipe. This guide part is then pushed into the lower end of the pipe and pulled up using a magnet with a hook that we provide.
Next step, screwing on the guide ring including the die holder
After the guide part has been pulled up, insert the flat steel to hold the dies and place it under the side so that it does not sag. In the picture, two flat steels hold the die holder at the right height so that the M 16 screw can still be inserted and tightened with a socket wrench including the guide ring
