What to do if the pressure increases when the spray gun is closed on my Landa PG4-3500 Pressure Washer?
If the pressure increases when the spray gun is closed on your Landa Pressure Washer, it indicates that the unloader valve is not operating properly. It is better to call local dealer.
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).
What to do if my Landa Pressure Washer engine will not start or stops while operating?
If your Landa Pressure Washer's engine won't start or stops during operation, it might be due to the low oil shutdown feature. Refill the engine with oil to resolve this issue.
What to do if the engine is overloaded on my Landa PG4-3500?
If the engine of your Landa Pressure Washer is overloaded, it could be due to a partially blocked nozzle (clean the nozzle) or excessive pressure from high engine RPM (adjust the engine throttle to lower the RPM).
Why is my Landa PG4-3500 losing pressure after a period of normal use?
If your Landa Pressure Washer experiences low pressure after a period of normal use, the nozzle may be worn. In this case, replace the nozzle.
Why is my Landa PG4-3500 dripping oil?
If your Landa Pressure Washer is dripping oil, the oil seal is likely worn. Call local dealer.

Open the spray gun or turn off the machine to prevent this. Another cause could be excess water supply pressure; place a pressure regulator at the end of the 50' garden hose.
Why is oil squirting out of the oil cap on my Landa PG4-3500 Pressure Washer pump?
