FAQ

Q Are you having trouble starting your gasoline sprayer?

A To begin the start-up process, fill the fuel tank with a 50:1 fuel mix. We recommend using Craftop Brand Oil the proper fuel mix ratio. Here is a link for a correct mix of oil and gasoline. The priming bulb is located towards the bottom of the carburetor. Pump the bulb 5-7 times until fuel begins to flow through the fuel pipes. Position the choke upright on a cold start (first start – right out of the box). Set the throttle to 50%. Pull the recoil starter 3-5 times to get the engine to start. Push the choke down once you hear the engine flutter (turn over). Set the throttle to 50%. To start the engine, pull the recoil starter. Allow the engine to warm up for 1-2 minutes at low throttle.

Q How should you rinse your gasoline backpack sprayer?

A Fill the tank halfway with fresh water. Then, pump the handle while holding the trigger wand open to spray out everything in the tank. Pump the handle a few dozen times while keeping the trigger open.

Q When and how often should I clean my gasoline sprayer?

A After each usage, your sprayer should be drained and cleaned. It is normally acceptable to leave the product in the sprayer if you intend to spray again later that day or the next day. If you are not going to spray again for at least a day or two, you will need to drain the tank. You should triple-rinse your sprayer after draining the tank. This entails flushing the system three times with fresh water to remove as much chemical residue as possible.

Q What is a gasoline sprayer?
