    • If this is your first time using a desoldering pump, try priming and activating the pump a few times before you use it for desoldering purposes.

    • Firmly grasp the desoldering pump with your hand.

    • Depress the plunger until it locks in place.

    • This primes the spring-loaded piston for suction.

    • To activate the pump, press the black side button.

    • This releases the spring-loaded piston, which creates a burst of suction at the nozzle.

    • The piston release creates a substantial kickback. Brace your hand when you use the pump to keep the nozzle steady.

    • Do not use the desoldering pump to desolder joints near small surface-mounted (SMT) components. The heat spillover and suction may dislodge the SMT components.

    • Prime the desoldering pump by depressing the plunger.

    • Heat the solder joint until the solder is liquified. To help with heat transfer, add some solder onto the soldering iron's tip.

    • Position the pump's nozzle as close to the molten solder as possible.

    • The nozzle is made of heat-resistant plastic, so don't worry if you occasionally brush the tip with it.

    • Press the side button to activate the pump.

    • Repeat the process until the joint is clean. You can also use solder wick to help soak up any remnant solder.

    • To clean the pump, prime and activate the pump a few times. This pushes a rod through the nozzle and ensures that solder doesn't block it.

    • On the rare occasion when the pump needs a more thorough cleaning, you can disassemble the pump to clean it out:

    • Grasp the nozzle by its knurled edge.

    • Twist the nozzle counter-clockwise to unscrew it. This may be difficult due to a tight-fitting O-ring.

    • Remove the nozzle and clean out the pump interior.

Good review, but I’ve found that these small solder suckers don’t do a very good job. The much larger “Soldapult” (https://www.edsyn.com/product/DS017.html) provides much more suction and can often completely clear a joint in one use.
