I have a KEW Hobby pressure washer 1985 and I need the rotating nozzel for the end of the wand to vary the size of the fan. Where can I get one?

pressure control valves are non adjustable
They operate to unload the pump when the trigger is released
What can vary pressure is the jet size at the end of the wand
The screw and nut on the valve is only to regulate the stop/start pressure as the trigger is pressed/ released
low pressure at the wand jet can be from low water supply to the pump or pump internal problems

frozen output valves were the hoses attach to. two or them are present. one is inside the other

Could be the input water pressure is not sufficient. There is a pressure valve inside the machine that will cut off the motor if input pressure is too low or non existent.

Try a different source for the water input.

hi try statring the machine with no hose on, if ok add the hose to the machine without the gun and lance. then try the gun on its own WITHOUT THE NOZZEL in the lance. just elimate things regards

I have a kew hobby 70 with little use. The nozzle wont spray, it just sends a weak jet of water. how can i fix it? I have hardly used it. It has been
in a shed for years . thanks

pluged sprayer nozzel.

sounds like nozzel has dirt in it -try removing and cleaning it - failling this get a drill bit of same size of hole in nozzel and drill hole clean.......
worked for me with same problem..........

the red button is just for the warning label. Did you pull the nozzle down. This nozzle is an adjustable nozzle. You push it in and this is for the soap injector and you pull it out for the pressure. If you have done this, then you may need to replace the nozzle. You can even put a quick diconnect on the end and use the small tips you can buy local or replace with the same type nozzle.
Also check to see if there is something blocking the hole.

Dear Osville,
It is not clear what type of lance or nozzel you have. You said that the machine works fine with the circulating water jet(the turbo). So it seems the machine is fine. I do sometimes service variable nozzels and variable lances. But the best solution is to replace nozzels and variable nozzles and lances with new ones. Regarding the fan spray setting it could have no pressure because it might be in the chemical setting. The chemical setting lets out a fan shape flow of water, but with less pressure. The chemical system only works on low pressure in domestic washers, that is why it needs a low pressure flat spray. The pencil jet has 2 jets comming out because if it is a lance or nozzel with ball bearings, these ball bearings must have stuck in a wrong position. Also 2 jets can come out, due to a damaged nozzel hole.
Altogether, the best advice is to buy a new nozzel or lance...which ever your machine uses. All Karcher machines have their own specific nozzels, lances and high pressure hoses. You cannot change these from one model to another.

Dear dennis_partr,
In general all pressure washers have a control valve. This is sometimes refered to as the Spill Valve. When the trigger is pulled, the spill valve is in normal position. When the trigger is released, the spill valve compresses to let water circulate from its bottom part. If when the trigger is pulled and the bottom part of the spill valve does not close, then water keeps on circulating and hence no pressure. In this case change the spill valve with a new one. Also there could be a fault in the sucktion valves. If the sucktion vaves do not close, also water keeps on circulating. One also can examine the delivery valves. If these are not closing, then water is being sucked while delivering. Hence no pressure. Another cause but very rare, is that the swash plate that is pushing the pistons got loose. The electric motor will be turning, but the pistons stay in the same position.
I mentioned many causes, but usualy it is the spill valve. If with a new spill valve, there is still no pressure....then you must tackle the sucktion and then the delivery valves.
I wish to add that I assume that you have the correct lance and correct nozzel size. A worn out nozzel, will result in low prssure too.
