  Fluctuating pressure in your Landa Pressure Washer can stem from several causes: the pump sucking air (check all pump lines and connections), or gasoline engine altitude (the gasoline engine is preset for operation at altitudes below 1000 feet above sea level. If operated at higher altitudes, it may be necessary to install a high altitude main jet in the carburator. Contact your local authorized engine sales and service center for details).

  If your Landa Pressure Washer engine will not start, it might be due to the low oil shutdown feature. Fill the engine with oil to resolve this.

  If water is leaking from the pump protector of your Landa Pressure Washer, it could be because the spray gun was closed while the machine was running for 5 minutes or longer (open the spray gun or turn off the machine) or due to excessive water supply pressure (place a pressure regulator at the end of the 50' garden hose).

Why is the operating pressure low on my Landa PG4-3500?

  Low operating pressure in your Landa Pressure Washer can be caused by several factors. It could be due to an insufficient water supply, such as a closed faucet or a garden hose that's too small. Make sure to use a larger garden hose, clean the inlet water screen, and fully open the faucet. Other potential causes include an old or incorrect spray nozzle (match the nozzle number to your machine or replace it), plumbing or hose leaks (check for leaks and re-tape with Teflon tape), a faulty or mis-adjusted unloader valve (adjust the unloader for proper pressure), the machine being stored in freezing temperatures (thaw it out completely), or slow engine RPM (it is better to call local dealer).
