What to Do If Your New Lawn Trimmer Isn't Working?

Investing in a new lawn trimmer should make your yard care easier — not more frustrating. But if your brand-new cordless trimmer won’t start or operate as expected, don’t worry. In most cases, you can quickly resolve the issue yourself, as it's usually something minor.

This guide walks you through:

1. Two Main Reasons Your Lawn Trimmer Doesn’t Work

1.1 Incorrect Setup or Operation

The most frequent cause of a non-working trimmer is improper setup. Even experienced users may miss a step with a new model.

Here are a few things to double-check:

Is the battery fully charged and securely inserted?
Did you press the safety lock button before squeezing the trigger?
Did you install the trimmer line/blades correctly?
Are all required attachments (guard, handle, etc.) in place?

Most cordless trimmers include built-in safety mechanisms. If you don’t install something properly, the device won’t power on. And even if the motor and battery work perfectly.

1.2 Product Fault or Manufacturing Defect

Less commonly, a component may be damaged or defective. This might include:

A malfunctioning battery or charger
A faulty motor or control switch
Loose internal wiring

These issues are rare but not impossible. That’s why it’s important to know how to quickly diagnose the problem.

2. How to Troubleshoot a Lawn Trimmer That Won’t Start

Try the following steps before contacting support:

Step 1: Battery Check

Ensure the battery is fully charged
Firmly insert it until it clicks into place
Try using a backup battery (if available) to rule out a battery issue

Step 2: Follow the Correct Startup Sequence

Most cordless trimmers have a dual-start safety system:

Press and hold the safety button
Then squeeze the trigger to activate the motor

If the safety button isn’t pressed first, the machine will not engage.

Step 3: Inspect the Cutting Head

Remove any debris, grass, or tangled line
Check that the trimmer line is long enough and properly wound
Make sure the protective guard is correctly mounted

Step 4: Listen for Sound or Vibration

If the motor hums but nothing spins, the shaft may be jammed
If there’s no response at all, the issue may be electrical (e.g., control board, switch, or battery contact)
