What to do if Lesco Premium Paint Sprayer nozzle tip leaks or has a poor spray pattern?
If your Lesco Paint Sprayer nozzle tip is leaking, has a poor spray pattern, a partial spray, or is completely stopped, it could be due to a missing or damaged flat seal or a clogged spray extension or nozzle. Replace the flat seal at the extension tip using Kit #7. Also, remove the nozzle and clean it as described in the Nozzle Maintenance section.
Why Lesco Premium leaks at the pump or doesn't build pressure?
If your Lesco Paint Sprayer leaks at the pump or doesn't build pressure, it could be due to several reasons: * Dirt or debris on the pump gasket or closure. * A chipped, torn, swollen, or defective pump gasket. * An issue with the check valve at the bottom of the pump assembly. * A worn or damaged o-ring on the piston. To resolve this, clean any dirt or debris from the gasket or closure. If the gasket is damaged, replace it as described in the Pump Disassembly & Reassembly section. Also, replace the check valve or o-ring if they are missing or damaged, following the instructions in the Pump Disassembly & Reassembly section.
How to fix Lesco Paint Sprayer nozzle that drips when shut-off lever is released?
If your Lesco Paint Sprayer nozzle drips when the shut-off lever is released, it could be due to dirt or debris in the shut-off valve or a damaged o-ring or seal in the shut-off (Kit #7). Clean the shut-off as described in the Shut-off Maintenance section. Additionally, service the shut-off seals as described in Maintenance service Kit #7.
Why is my Lesco Premium difficult to pump?
If your Lesco Paint Sprayer is difficult to pump, it could be due to a damaged piston o-ring or a dry piston o-ring. Replace the piston o-ring as described in the Pump Disassembly & Reassembly section. If the o-ring is simply dry, lubricate it as described in the Pump Disassembly & Reassembly section.
What causes Lesco Premium material to overflow through the pump barrel?
If sprayer material overflows through the pump barrel or the pump handle rises when unlocked on your Lesco Paint Sprayer, it may be caused by dirt or debris under the check valve on the pump, or a chipped, torn, or swollen pump check valve. Clean the check valve and valve sealing surface on the pump. If the check valve is damaged, replace it as described in the Pump Disassembly & Reassembly section.
What to do if Lesco Premium Paint Sprayer hose leaks at the tank or shut-off?
If the hose on your Lesco Paint Sprayer leaks at the tank or shut-off, it could be due to a loose hose or a cracked, swollen, or faulty hose. Try tightening the hose nut. If that doesn't solve the problem, replace the shut-off assembly.
Why does Lesco Paint Sprayer start spraying when pumping or not stop when shut-off lever is released?
If your Lesco Paint Sprayer starts to spray when pumping or does not stop spraying when the shut-off lever is released, the shut-off lock is likely engaged. Squeeze the shut-off lever and rotate the lock towards the nozzle as described in the Spraying and Locking section.
What to do if Lesco Premium tank leaks?
If there is evidence of spray material escaping from the tank of your Lesco Paint Sprayer, replace the entire sprayer.
What to do if my Lesco Premium will not turn on?
If your Lesco Paint Sprayer isn't turning on, first ensure the battery is correctly inserted and charged. Then, set the power switch to the ON position. If it still doesn't work, the battery may be damaged or overheated, in which case you should replace it or allow it to cool. Also, check if the hose is already pressurized, which might cause the pump to turn off automatically; open the shut-off to see if spraying starts.
Why my Lesco Premium Paint Sprayer turns on but doesn't spray?
If your Lesco Paint Sprayer turns on but doesn't spray, the possible causes are: * The tank may be empty, so add liquid to the tank. * The shut-off may be clogged, so clean the shut-off. * The nozzle may be clogged, so clean the nozzle. * The pump may not be primed yet, so allow time for the pump to prime (up to 30 seconds).
