Cordless chainsaw safety

Cordless saws made chainsaws far more accessible. No fuel to mix, no pull cord, no exhaust, and a tool light enough that plenty of people who would never have bought a gas saw now own one. None of that changed what a moving chain does, and the published safety guidance is unchanged with it.

The protective equipment list

The published distances

These are the two figures most likely to be ignored in a suburban garden, where everyone is closer to everything.

The two-tree-lengths rule is worth reading twice. It is a distance defined by the tree, not by the saw, and it is the reason felling in a confined space is professional work regardless of what you are cutting with.

Cutting practice

1. Cut at waist level or below. CDC guidance names this directly, to ensure you maintain secure control. Anything above that is a pole saw job.
2. Check the area first for hazards like nails or cables, and confirm power lines are de-energized before working anywhere near them.
3. Clear cut limbs as you work. Guidance is explicit that clearing the area of cut limbs and wood allows safer use — the trip hazard is created by the job itself.
4. Treat spring poles with extreme care. CDC guidance for bent or tensioned trees is to slowly shave the underside rather than cut through, so the tension releases slowly.
5. Both hands, always. One-handed operation removes your ability to resist a kickback at the only moment it matters.
6. Plan the escape route before the cut, not during it.

What is different about a cordless saw

Some of it helps and some of it creates new habits worth naming.

The pre-start checks

CDC guidance covers the machine as well as the operator, and every item on its list applies to a battery saw.

• Operate, adjust and maintain to the manufacturer's instructions. The manual is the authority, not us.
• Properly sharpened teeth. A dull chain is pushed rather than fed, which is how cuts wander and how kickback opportunities are created.
• Properly lubricated bar, with bar and chain oil. The EGO PSA1000 publishes automatic lubrication; on the CS1804 check the reservoir before every session.
• Correct chain tension, checked and adjusted periodically. Detail in the chainsaw maintenance guide.
• The right size saw for the job, with safety features. An 18 inch bar is more saw than most limb work needs.

Overhead work is a different tool

The guidance to cut at waist level or below rules out a large fraction of what people buy chainsaws for. A pole saw is the published answer: the EGO PSA1000 has a 10 inch bar on a 38 inch pole at 4.17 lb, with automatic lubrication and up to 70 published cuts on a 2.5Ah pack.

It keeps you on the ground and keeps the cutting head away from your body, which are the two things a chainsaw held overhead on a ladder does not. The full comparison is in pole saw vs chainsaw.

When not to do it yourself

• Any tree where you cannot clear two tree lengths, or at least 150 feet, of people
• Anything near power lines that have not been verified de-energized
• Anything that requires a ladder and a running saw at the same time
• Storm-damaged trees under tension, where the spring-pole hazard is unpredictable
• Any cut you cannot make at waist level or below with secure footing

What we cannot tell you

We are not a safety authority and this page is a summary of published CDC guidance rather than training. We have not used any of these tools. Chainsaw operation is a skill, formal training exists, and for felling in particular the honest recommendation is to hire someone.

What the published guidance gives you is specific and checkable: a six-item equipment list, two bystander distances, a maximum cutting height and a named procedure for tensioned wood.
