Figuring out your leaf blower’s make and model

Before you grab your toolbox, it’s important to know the brand and model of your leaf blower. Brands like Toro, Husqvarna, and Echo might have their own parts and repair steps. Finding the model number helps ensure you’ve got the right instructions and replacement bits.

Safety first: what you need to know

Your well-being comes first when tinkering with tools. Keep these safety tips in mind:

• If working indoors, make sure there is adequate ventilation to prevent the buildup of exhaust fumes. Carbon monoxide poisoning can be a serious risk.
• Wear insulated work gloves to protect your hands from sharp metal parts, pinching hazards and debris.
• Never attempt to service or repair while it is running or when the engine is still warm. Wait for all moving parts to come to a complete stop.
• Exercise extreme caution when working near blades, augers, or any other moving parts. Keep your hands, fingers, and clothing clear of these areas at all times.
• If the appliance has recently been used, give it plenty of time for any hot parts to cool down before working on it. 
• Empty the gas tank before beginning any work. Refill using fresh fuel. 
• When working with wires, avoid touching any exposed wires or terminals. If you need to touch a wire, use a non-conductive tool or wear insulating gloves to prevent electrical shock.
• Take your time and don’t rush while working to prevent accidents and personal injuries.
• Work in a well-lit area so you can clearly see and access the interior parts.
• Clear your workspace of clutter and other obstacles. Keep children and pets away from the work area.
• Be gentle when handling or removing parts. Excessive force might damage the appliance or cause injury.
• Wear safety glasses when working with chemicals, dust or cleaning large debris to prevent injury. 
• When not in use, store the machine in a safe and dry location.

Gather your tools

Having the right gear makes the fix a lot smoother. Depending on your model, you might need:

• T-25 Torx screwdriver: Common for Torx screws on outdoor gear.
• Phillips screwdriver: For the usual screws.
• Proper socket or wrench: To remove any nuts or bolts holding things together.

Steps to fix the throttle trigger

Removing the engine cover and handle pieces

First up, you’ll need to take off the screws holding the engine cover and handle sections. Here’s how:

1. Spot all the screws on the engine cover and handles.
2. Use the T-25 Torx or Phillips screwdriver as needed.
3. Carefully remove the screws and stash them somewhere safe.
4. Gently split the handle halves to get to the inside parts.

Unhooking the throttle linkage and old trigger

With the handle open:

1. Find the throttle linkage that’s connected to the trigger.
2. Gently detach the linkage. Pay attention to how it’s hooked up so you can put it back together later.
3. Slide the old trigger off its post.

Cleaning the trigger area (if you’re keeping the old trigger)

If you’re just giving the existing trigger a good cleaning:

1. Check the trigger for any gunk or damage.
2. Use a soft brush or cloth to wipe away dirt and debris.
3. If needed, apply a tiny bit of lubricant to keep things moving smoothly.

Popping in the new throttle trigger

If you’re swapping in a new trigger:

1. Line up the new trigger on the handle post.
2. Reconnect the throttle linkage to the new trigger, making sure it’s secured just like it was before.
3. Double-check that the throttle cable sits properly in the guide to avoid any snags.

Putting the handle and engine cover back together

With everything fixed up:

1. Carefully align the handle halves, ensuring no wires get pinched.
2. Place all the screws back in, starting them by hand to prevent any cross-threading.
3. Use your screwdriver or socket to snug them up. Don’t go overboard—you don’t want to strip anything.
4. Reattach the engine cover, securing it with its screws.

Reconnecting the spark plug wire

To wrap things up:

1. Slide the boot back onto the spark plug until it sits firmly.
2. Make sure it’s on there good and tight for a solid connection.
