If you have a garden or lawn to maintain, a petrol strimmer can be a handy tool to have.

Strimmers, also known as string trimmers or weed whackers, are perfect for keeping overgrown grass, weeds, and unruly vegetation in check. However, if you are new to using a petrol strimmer, getting started might seem a bit daunting. Fear not!

In this article, we will walk you through everything you need to know about starting and using a petrol strimmer like a pro. From safety precautions to step-by-step instructions, we’ve got you covered.

How to Start a Petrol Strimmer

How to Start a Petrol Strimmer

Starting a petrol strimmer for the first time requires some basic knowledge and preparation. Follow these steps to ensure a smooth and successful start:

Safety First: Gear Up!: Before starting the petrol strimmer, prioritize safety. Wear appropriate personal protective equipment (PPE) such as safety goggles, ear protection, gloves, and long pants. Make sure your clothing is snug-fitting to avoid entanglement with the strimmer’s rotating parts.

Check the Fuel and Oil Levels: Ensure there is enough fuel and oil in the strimmer. Refer to the manufacturer’s instructions for the correct fuel-oil mixture ratio. Using the wrong mixture can damage the engine or cause performance issues.

Inspect the Strimmer: Thoroughly inspect the strimmer for any visible damage or loose parts. Check the cutting head, guard, and handle for proper alignment and secure attachment.

Prime the Engine: To prime the engine, press the primer bulb several times until you see fuel flowing through the fuel lines. This helps in easier starting by filling the carburetor with fuel.

Set the Choke and Throttle: Set the choke to the closed position if the engine is cold. If it’s warm, keep the choke open. Adjust the throttle to the “Start” position.

Place the Strimmer on the Ground: Place the strimmer on a flat, stable surface, preferably the ground. Ensure the cutting head is away from any obstructions.

Pull the Starter Cord: Grasp the starter cord firmly and give it a smooth, steady pull. The engine should start with a purring sound. If it doesn’t start on the first try, give it another pull while following the proper starting technique.

Warm Up the Engine: Let the engine warm up for a minute or two before proceeding. This ensures the engine reaches its optimal operating temperature.

Disengage the Choke and Adjust the Throttle: Once the engine is warm, disengage the choke and adjust the throttle to the desired speed for strimming.

Start Strimming!: Hold the strimmer with both hands and begin strimming by moving the cutting head along the ground in a smooth, sweeping motion. Keep a steady pace to achieve even results.

Tips for Using a Petrol Strimmer Effectively

Tips for Using a Petrol Strimmer Effectively

Using a petrol strimmer effectively requires more than just knowing how to start it. Here are some valuable tips to enhance your strimming experience:

Maintain the Right Cutting Height: Adjust the cutting height of the strimmer based on the vegetation you are trimming. For long grass or weeds, a higher cutting height is suitable, while shorter grass requires a lower setting.

Edge Carefully: When edging along pathways or flowerbeds, tilt the strimmer head vertically to create a neat and precise edge. Take it slow to avoid damaging nearby plants or surfaces.

Keep an Eye on the Line: The strimmer’s cutting line will wear down with use. Check regularly and replace it when it becomes too short. Using a worn-out line reduces cutting efficiency.

Avoid Strimming Near Solid Objects: Avoid strimming near solid objects like rocks, tree trunks, or fences. The cutting line can break or wear out quickly when it comes into contact with hard surfaces.

Use the Right Technique: Move the strimmer from side to side in a steady motion to achieve even cutting. Overlapping your strokes slightly helps prevent missed patches.

Clear Debris Regularly: Stop the strimmer and clear debris from the cutting head to prevent it from getting clogged. This will maintain optimal cutting performance.

Frequently Asked Questions

How often should I check the fuel and oil levels in my petrol strimmer?
Checking the fuel and oil levels should be part of your pre-strimming routine. Before every use, ensure there is sufficient fuel and oil, following the manufacturer’s guidelines on the fuel-oil mixture ratio.

Is a petrol strimmer more powerful than an electric one?
Yes, petrol strimmers are generally more powerful than electric ones, making them suitable for larger or more challenging areas with thicker vegetation. However, they are also heavier and noisier.

Can I use a petrol strimmer on a sloped terrain?
Yes, you can use a petrol strimmer on a sloped terrain, but exercise caution. Always work across the slope, not up or down, to prevent accidents and ensure stability.

How long does the cutting line last before I need to replace it?
The lifespan of the cutting line depends on usage and the type of vegetation you are trimming. On average, you may need to replace the line every 5 to 10 hours of strimming.

Can I use a petrol strimmer to trim around trees and delicate plants?
Yes, you can trim around trees and delicate plants using a cordless strimmer, but be gentle and use a low throttle setting. Consider using a handheld edging tool for more precise work.

What maintenance does a petrol strimmer require?
Regular maintenance includes cleaning the air filter, inspecting spark plugs, lubricating the gearbox, and sharpening or replacing cutting blades or lines.


Now that you’ve mastered how to start a petrol strimmer and learned some valuable tips for effective strimming, you’re ready to tackle your garden with confidence.

Remember to prioritize safety, follow proper starting procedures, and use the strimmer with care.

With the right technique and maintenance, your petrol strimmer will be a reliable tool for keeping your garden pristine throughout the seasons.
