Pump Lever (Side Handle): The long, L-shaped black metal rod lying on the floor in front of your box. It inserts into the bottom rocker bar of the sprayer and is manually pumped up and down to build air pressure inside the internal tank chamber. Split Pin & Washer: Used to securely link and lock the pump lever arm to the sprayer base frame. Spray Wand (Lance) & Trigger: Connects to the flexible hose. The hand trigger features a built-in locking mechanism to support continuous, hand-fatigue-free spraying. Nozzle Attachment Tips: The small plastic caps that screw onto the end of the spray wand to change your spray pattern from a direct stream to a wide mist.
