Congratulations on your new backpack sprayer! In order to ensure your sprayer functions properly and lasts a long time, it’s important to start it up correctly.
If you are having trouble starting your engine, there are a few ways to troubleshoot the issue.
Compatible with backpack sprayers TCS6.5, TPS25, and CPS435. All of these backpack sprayers contain 2 Stroke engines.
In this video, our team demonstrates how to start up a backpack sprayer along with tips to get it going if issues arise.
- To begin the start-up process, use 50:1 fuel mix to fill the fuel tank.
- Any brand is suitable, as long as it contains the correct fuel mix ratio.
- Access the primer bulb towards the bottom of the carburetor. Pump the bulb 5-7 times until you see fuel flowing through the fuel lines.
- During a cold start (initial start - fresh out of the box), position the choke upright.
- Place the throttle at 50%.
- Pull the recoil starter 3-5 times for the engine to turn over.
- Once you hear the engine flutter (turn over), push the choke down.
- Leave the throttle at 50%.
- Pull the recoil starter to get the engine started.
- Let the engine idle at a low throttle for 1-2 minutes to warm it up.
Pulling on the recoil starter and the engine will not turn on.
This could be due to the engine flooding. To verify if this is the issue, begin by taking a look at the spark plug.
- Access your tool kit from the backpack sprayer box.
- Locate the spark plug removal tool. It is the “T-shaped” metal tool.
- Lift the rubber cover that is protecting the spark plug to access it.
- With your metal tool, use the side that is shaped as a hexagon and place it over the spark plug.
- Turn it counter-clockwise to loosen the spark plug.
- Once loosened, take out the spark plug and examine for any moisture present.
- Let the spark plug dry out by air-drying or pat dry gently using a thin paper towel.
- Wait until the spark plug is completely dry, or replace it with a new plug.
- To place the spark plug back in, screw it into place. You can use the tool to tighten.
- Place the rubber cover back on.
- Repeat the steps given above that explain the original start-up.
Engine will not start because of altitude and lack of oxygen in the air.
- In your tool kit, access the carburetor adjustment tool.
- Place the tool into the black circular insert located on the carburetor.
- With the engine on, slowly rotate the tool counter-clockwise and listen for a steady “hum” of the engine.
- Adjust as needed.
We hope these tips have helped you start your engine smoothly!
