Please check adapter size and make sure it fits your machine. We dont take any responsibility for theincompatibility of adapter. If you are not clear please contact us and send us the photo of your gun and lance we will help to choose the suitable adapter. Setting up your foam generator: 1. Screw on your chosen adapter to the brass body. Ensure there is adequate PTFE tape on the threads before screwing the adapter on. Not using PTFE tape will cause water leaks and air leaks affecting the usability of the foam generator. 2. Attach the suction tube to the brass body inlet port. 3. Fill up the plastic bottle with plain water and run it through your pressure washer. Check for leaks and check the lance is working correctly. 4. Once you are satisfied there are no leaks and the lance is functioning correctly fill up an inch of your dedicated snow foam cleaner in the bottle and appropriate amount of water. 5.After every use you must follow through with plain water for 30 seconds to flush out any snow foam cleaner. If left in the mesh filter can become scaled and blocked. Using Tips: 1.Higher pressure from pressure washer better foam from foam generator. To get the thick foam as the photo above the pressure of pressure washer should be more than 140bar. 2.If your pressure washer has 100~130bar only please disassemble stainless steel nozzle from foam generatorwith flat screw driver and install brass nozzle (comes with parcel).Please screw the brass nozzle a little loose if your pressure washer works intermittently (on and off). 3.High foam of snow foam cleaner is important. The general car washing shampoo may not generate thick foam. 4.For better foam 20% snow foam cleaner+80%warmwater is suggested.You can reduce the water amount accordingly if arent satisfied with the foam quality. 5. To prolong the life of foam generator after every use you must follow through with clean water for 30 seconds to flush out any snow foam cleaner. If left in the mesh filter can become scaled and blocked. If the foam generator cant work properly please try to check following points: 1.If the pressure washer is functioning correctly. There is no water leaks and air leaks anywhere. 2.If the pressure and flow from tap water is insufficient. The foam generatorcant create foam at low pressure and water flow. Also the self-priming function cant be applied when you are using foam generator(i.e. The inlet water cant come from pool or bucket). 3.If somewhere offoam generatoris blocked by debris dried detergent or sealing tape. Please check the stainless steel nozzle detergent suction nozzle and mesh filter. (Please contact us if you dont know how to disassemble the foam generatorand clean mesh filter)
