Safety precautions

When working on any appliance, remember to keep safety first. Here are some tips to keep 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.

Problem 1: The blower won’t start

If your corded leaf blower doesn’t turn on, the issue is often related to the power source or internal wiring.

1. Check the outlet: Plug another device (e.g., a lamp or phone charger) into the same outlet to ensure it’s working. Reset the circuit breaker if the outlet isn’t providing power.
2. Inspect the power cord: Look for visible damage, such as cuts, fraying, or exposed wires. Replace it if necessary. Ensure the cord is securely plugged into the outlet and the blower.
3. Testing and replacement: Use a multimeter to check the on/off switch for continuity. If it doesn’t show continuity when the switch is engaged, it may be faulty. Replace a damaged power cord with a new one that matches the blower’s specifications.

Problem 2: The blower loses power during use

A blower that stops working intermittently may have loose connections, overheating issues, or an overloaded circuit.

1. Check for loose connections: Ensure the power cord is firmly plugged into both the outlet and the blower. Inspect the internal wiring for loose or disconnected terminals.
2. Test for overheating: Most corded blowers have a thermal cutoff feature to prevent motor damage. If the blower shuts off after extended use, let it cool for 20–30 minutes before restarting.
3. Avoid circuit overload: Ensure you’re not using multiple high-power devices on the same circuit as the blower.
4. Testing and replacement: Tighten or reattach loose internal connections with electrical tape or proper connectors. Replace any wiring that appears damaged or frayed.

Problem 3: The blower doesn’t reach full power

Weak performance is often due to motor strain, an extension cord issue, or blockages.

1. Inspect the extension cord: Check the cord’s length and gauge. A cord that’s too long or thin may not deliver sufficient power. Use a heavy-duty extension cord rated for outdoor use (e.g., 12- or 14-gauge).
2. Check for blockages: Turn off the blower and inspect the air intake and output vents for debris. Clear any obstructions.
3. Clean the motor and fan: Remove the housing to access the motor and fan. Dust and debris can reduce efficiency. Use compressed air or a soft brush to clean them.
4. Testing and replacement: If the motor still doesn’t deliver full power, it may need servicing or replacement.

Problem 4: The blower is unusually noisy

Excessive noise could be caused by loose components, a misaligned fan, or worn motor bearings.

1. Tighten screws and bolts: Inspect the blower housing and handle for loose fasteners. Tighten them securely.
2. Check the fan alignment: Remove the housing and inspect the fan. If it’s off-center, adjust it until it’s properly aligned.
3. Inspect the motor bearings: Worn bearings can produce grinding or squealing noises.
4. Testing and replacement: Replace a damaged fan or impeller. If the bearings are worn, replace them with a compatible part.

Problem 5: The blower overheats

Overheating can result from restricted airflow, prolonged use, or motor issues.

1. Inspect air vents: Ensure the air intake and exhaust vents are clear of dust, leaves, or debris. Blocked airflow causes the motor to overheat.
2. Avoid prolonged use: Give the blower a break every 20–30 minutes to prevent overheating.
3. Check the motor: Remove the housing and inspect the motor for dust buildup or worn components.
4. Testing and replacement: Clean the motor and vents thoroughly with compressed air. If overheating persists, the motor may need to be replaced or serviced.
