from lesco. can anyone give me detailed instructions on how to fix this? thanks.
what do you mean 'over pumped '?
i had to fix one once, good luck, its a pain in the ass, if you don't have the manual, your lesco can make a copy for you, it has a diagram that you can look at to rebuild it, ouchy
never had issues with my swissmex's though
Buy a new one. The diaphragm pumps are nearly impossible to rebuild. The piston pumps aren't too bad if you can find the rebuild kit.
what model is it piston or diaphram???? are they the solo type??
both have the same relaese valve in them. inside the tank there is a black top with a pionter and numbers on it. you need to push down and turn it this allows over pressure to bleed back into the tank. if this adjustment gets clogged you can overpress. and cause damage.
it's a regular lesco one.
I recommend doing away with your current backpack sprayer. Buy a battery-powered Shurflo SRS-600. They spray up to 120 gallons on a single charge. You can find them on ebay for $175 - $180 including shipping. (no tax to pay either). The only prob with the SRS-600 is the gun......We have always had to upgrade the spray gun within 2 - 6 weeks after purchase, but after that....they last and last. Plus no more handle to pump. I consider these units to be the best in the industry. My guys love 'em! Now they actually do a thorough job of spot spraying.
Lesco private labels both a piston & a diaphragm Solo. Which one you have will determine whether it's worth rebuilding.
it is the 051660 series. piston pump lesco brand.
