A battery-powered chainsaw is one of the most useful tools you can have around the yard, but it’s also a tool you need to respect. You have to take the time to maintain your cordless chainsaw and take the steps needed to stay safe while you use it.

Benefits of a Battery-Powered Chainsaw

Battery-powered chainsaws, or cordless chainsaws, are more powerful and versatile than ever. A battery-operated chainsaw can be a great option when compared with a gas model for a few reasons:

  • It’s easier to start.
  • It runs quieter.
  • It has lower emissions.
  • It weighs less.
  • It doesn’t require as much maintenance. 
     

See our Chainsaw Buying Guide to compare different types of chainsaws and learn how to find the best chainsaw for the type of cutting you need to do.

Battery-Powered Chainsaw Safety and Protective Gear

Before you start cutting, make sure to read your user manual and always follow the safety recommendations.

Let’s take a look at the safety features on this saw.

Safety Features on the Battery-Powered Chainsaw

The Chain Brake: If the saw kicks back, the chain brake will hit your hand and engage to immediately stop the chain from moving.

The Chain Oiler: Oil from this reservoir will automatically lubricate the bar and chain to prevent overheating and binding.

The Chain Adjustment Knob: Use this to adjust the chain tightness to avoid binding or derailing.

Caution

Different cordless chainsaws have different features. Read the manual and become familiar with the safety features on your saw and see Chainsaw Safety.

Safety Gear for Using a Battery-Powered Chainsaw

You’ll also need safety equipment to protect yourself as you work.

  • A hard hat, ear protection and eye protection are a must. Better yet, also wear a face shield to protect yourself from flying debris.
  • You’ll need heavy gloves with an enhanced grip surface.
  • Sturdy boots with steel toes and nonskid soles will protect your feet.
  • Chainsaw safety chaps are more than pants — they’re made of ballistic fibers that will tangle into the chain and stop the saw, protecting your legs and keeping you safer. These are worth every penny and a must-have whenever using a chainsaw. Wear them over long pants.

Removing the Battery From the Chainsaw

Before performing any maintenance on a battery-operated chainsaw, make sure you have completely removed the battery. If you’re used to a gas-powered saw, expect to hear the engine idling as a warning that the saw is live. A battery-powered saw is always live as long as the battery is connected, so be extra careful about removing that battery every time you touch the bar or chain.

Maintaining a Battery-Powered Chainsaw Chain

To operate safely, your saw must be maintained properly. A battery-powered chainsaw is a lower-maintenance option, but there are some necessary steps for proper care and safe cutting. One of the key areas that needs attention is the chain.

Before you use the saw, with the battery disconnected, check the chain tension. You should be able to pull the chain down slightly from the bar, but it should not be slack. Some brands use a tool for tension, but some are toolless and use a tensioner knob. Regularly inspect the bar and clean it if needed. The chain will need to be sharpened regularly. If you use a filing kit, you can do it fairly easily.

Caution

Follow the manufacturer’s instructions for battery-powered chainsaw and chain maintenance, including battery charging, storage and care.
