Types of power saws
Power saws are chain cutting machines used for tree felling, thick branch pruning, firewood preparation, and post-storm clean-up. The category includes the following models for different needs:
- Petrol-powered chain saws: For felling large-trunked trees and preparing firewood with powerful motors.
- Battery-powered telescopic pruning saws: For pruning high branches without a ladder, thanks to their extendable poles.
- Petrol-powered pole pruning saw and brush cutter combinations: Models that combine different tasks in a single body with interchangeable heads.
The engine displacement (cc), power (kW), and bar length (inch) in product names give an indication of the saw's cutting capacity.
Selection criteria
The thickness of the trees to be cut determines the bar length; the bar must be longer than the diameter of the trunk to be cut. Lightweight models are preferable for occasional pruning and firewood tasks, while more powerful models are better suited to frequent and heavy cutting work. Telescopic saws are far safer than using a ladder for high branches. Battery-powered models are a quiet, low-maintenance alternative.
Safety
The use of a power saw carries serious accident risks. A helmet, face shield or protective goggles, ear protection, cut-resistant trousers, gloves, and work boots must always be worn. The saw must be held with both hands, and cutting must not be performed with the tip of the bar; contact with the tip can cause a dangerous reaction known as kickback. The chain brake and other safety features must be checked before each use. Felling large trees requires experience; professional assistance should be sought for large trees.
Maintenance
Keeping the chain sharp and at the correct tension improves both safety and cutting efficiency. The chain oil reservoir must be checked before each use, and the automatic lubrication system must be confirmed to be working. For two-stroke petrol engines, the fuel-to-oil mixture ratio must be prepared according to the manufacturer's recommendation.
Frequently asked questions
How do I choose bar length?
It is chosen according to the trunk diameter to be cut; the bar must be longer than the diameter.
Is a battery-powered saw sufficient for cutting firewood?
It may be sufficient for light to medium-intensity tasks; petrol-powered models are more suitable for intensive firewood cutting.
When should the chain be sharpened?
Sharpening is needed when sawdust turns to fine powder and cutting becomes labored.
How can kickback be prevented?
Not cutting with the upper tip of the bar and checking the chain brake reduces this risk.
How is the fuel mixture prepared?
The ratio is stated in the operator's manual; the correct ratio is important for engine life.
Where can I find pruning shear options?
