20 Most Recent Laguna MaxFlo Pond Pump 900 GPH () Questions & Answers

This is a membrane pump - an electromagnet moves up and down a piston suspended with a spring; this piston is attached to a rubber membrane that closes a chamber; in this chamber are also 2 unidirectional valves, one to **** the water the other to push it out.
In your case that membrane burst and it should be replaced. Unfortunately this part is not supposed to be a replaceable one and because of that the unit is sealed with waterproof glue. To access the membrane you will have to crack the case open with a sharp knife, then replace the membrane with a home-made one (from a piece of rubber mat) and glue it in place, then glue back the case. This is a very long and fiddly job that you must do yourself since no one else would.
Or you could just discard this pump and get a new one

You can reduce the flow using a ball valve on the outlet side of your pump. This is good for limiting the flow up to about 20% without adding too much strain on your pump. If you need to reduce it more use a Tee fitting and attach a second ball valve to the return just before the first valve to return water to your sump and prevent over pressurization of the pump. Please excuse the crudeness of the diagram.

It almost sounds as if the thermal load protection fault is being tripped on the pump. When the pump kicks off is the housing extremely warm? If so you may need to replace the pump.

whatever the manual tells you

That is usually caused by hangups in the pull starter system creating too much friction and not transferring the pull to the motor. Here is the parts diagram and exploded view

A single pole push button would tie the fused battery feed at the ignition switch B terminal (red/white wire) to the ignition switch S terminal (orange wire).

This provides the same function as turning ignition switch to the start position with all safeties remaining functional. For engine run the ignition switch must be in run position. Push and hold push button until engine run. Turn ignition switch to off position to kill engine.

See link below for wiring diagram located in parts section of manual.

Though I have never heard of Yellowstone appliances, I am pretty sure there is a way to get replacement parts from the company spare parts department or from other sources who sell these pressure washers. If not, try the Internet, or try the Speed shops where they sell these to people who pressure wash their cars/trucks. I am also sure there are other hoses not necessarily for the Yellowstone brand but fit perfectly well on them. Find out where they sell other brands and take your washer to them, ask them if they can sell you a hose with the right connectors to fit your washer. No salesperson can refuse to sell you a good bargain.

Make sure that the nozzle is clean. Also the tube between the nozzle and tank. Check inside the tank to be sure there is not any debris in the tank. Is the pump working and building up pressure? Does the cap O ring make a good seal?

This is how to solve the stiff Makita plunge saw easily!!!
I've just carried out the following steps and it's like a new saw.
Clear a table top and grab the following tools:
Philips screw driver
4mm allen key
grease- i used silicone grease
1. Take the base off the saw by removing the 4 x obvious screws.
2. If you look at the saw, you'll see that is pivots on a single pin at the rear. You'll also notice that there is a 4mm allen screw driven into that pin.
3. Remove the 4mm allen screw.
4. Fill the screw hole with grease and drive the 4mm allen screw back in (it'll force grease along the pin internally). Do this 3 or 4 times.
5. Work the mechanism back and forth as if you're plunging the saw- you'll notice that it becomes so much more easy to move.
6. Wipe away the black dirty grease that you have forced out of the pin. Reinsert the 4mm allen screw and tighten
7. refix the base and spring.
8. Job done.
This actually bugged me for ages until i finally decided to have a look and see what the issue was.
