Operating an 18-inch chainsaw safely starts before the engine does: read the manual, gear up, and inspect the saw first.
For the full breakdown, see our best 18 Inch Chainsaw guide.
Knowing how to safely operate an 18-inch chainsaw for beginners is mostly discipline. The rules below follow OSHA’s chainsaw guidance and STIHL’s safety manual: read the saw’s own operator’s manual, wear the full PPE set, inspect before every use, and never cut alone or above shoulder height.
The Pre-Start Routine for an 18-Inch Chainsaw: Read, Inspect, Test
The operator’s manual is the safety document for your exact model, not a formality; OSHA says to follow manufacturer instructions for operation and maintenance. STIHL’s chainsaw safety manual adds that you should never run a saw that is missing its front hand guard.
- Inspect the controls, bolts, handles, chain tension, and all safety devices before every start.
- Confirm the chain brake engages and releases cleanly, and that the front hand guard moves without binding.
- Keep the chain sharp. A dull chain makes you push the saw, and pushing is when control disappears.
On an electric 18-inch saw, hold the insulated grip so a chain that touches hidden wiring cannot shock you, and choose a model tested by a Nationally Recognized Testing Laboratory.
Chainsaw protection covers much more than your eyes.
| PPE Item | What It Protects | Notes For Beginners |
|---|---|---|
| Eye protection | Eyes from chips and debris | Safety glasses or goggles, worn from the first pull of the cord. |
| Face protection | Face and neck if the bar kicks | Mesh screen or a helmet-mounted visor. |
| Hearing protection | Ears from hours of saw noise | Earmuffs or plugs rated for the saw’s noise level. |
| Head protection | Skull from branches and kickback | A hard hat; helmet systems combine all three head pieces. |
| Hand protection | Grip, vibration, and minor cuts | Non-slip gloves with cut-resistant palms. |
| Leg protection | Thighs if the bar touches them | Chainsaw chaps are the standard defense. |
| Foot protection | Feet and ankles from dropped wood | Steel-toe or composite-toe boots. |
How Do You Start and Cut Without Kickback?
Start the saw on the ground or another firm support with the chain brake engaged. OSHA’s chainsaw safety training materials are clear that drop-starting and throw-starting are out. From there, both hands stay on the saw — right on the rear handle, left on the front — and both feet stay on stable ground.
- Cut only below shoulder height, never directly overhead, so any kickback reaction stays in front of you.
- Clear the work area first: mark it, remove anything that blocks footing or a retreat path, and look for nails, spikes, or metal in the wood before you cut.
- Keep all bystanders and animals well away, and never work alone — a partner is the rule, not the exception.
Kickback is the chainsaw danger beginners hear about most, and for good reason: when the upper tip of the bar touches wood, or the chain gets pinched, the bar whips up and back toward your face. Cut one thing at a time and never force the saw; let the chain do the work.
Fatigue and impairment belong in the same risk calculation: skip the saw when you are tired, ill, upset, or after alcohol, drugs, or medication. Run the saw only outdoors or in a well-ventilated spot, since gas models produce carbon monoxide. Stop the motor before setting the saw down or moving it any distance, engage the chain brake if you carry it more than 50 feet or across rough terrain, fit the bar guard for transport, and never carry a chainsaw in a vehicle’s passenger seat.
Run the whole routine in order: read the manual, inspect the saw, put on the full kit, then start on the ground with the brake on. When the cut is finished, stop the engine, lock the brake, and cover the bar before you walk anywhere.
FAQs
What actually causes chainsaw kickback?
Kickback happens when the upper tip of the bar — the kickback zone — touches wood, or when the chain gets pinched inside the cut. The bar whips up and back toward your face. Two hands on the saw, no tip contact, and a working chain brake and low-kickback chain make it far less likely.
Is it ever safe to run a chainsaw alone?
A second person can call for help, manage an emergency, or spot hazards you cannot see while cutting. Even a small injury becomes a serious problem when nobody is there to help.
Why does an 18-inch chainsaw need a bar cover?
A bar guard keeps the chain covered when the saw is not cutting, protecting both the chain and anyone near it.
