Engine Types, Power Options, and Guide Bar Sizes
Chainsaws are categorized by their power source into petrol-engine, electric corded, and modern lithium-ion cordless battery models.
Selecting the appropriate engine displacement and bar length depends on trunk diameter and operational portability requirements.
- Petrol chainsaws: Powered by 2-stroke internal combustion engines (45cc to 65cc displacement) delivering immense cutting power for heavy forest timber and orchard felling.
- Battery cordless chainsaws: Powered by 36V or 40V lithium-ion batteries; lightweight, quiet, emission-free, and ideal for orchard pruning and farmstead branch trimming.
- Guide bar lengths: Available in 12 to 16-inch bars for light pruning and 18 to 24-inch heavy-duty bars for felling mature timber trees.
- Safety features: Built-in inertia chain brake, front hand guard, safety throttle lockout, and chain catcher prevent operator injury during kickback.
Operational Safety, Maintenance, and Subsidy Support
Chainsaw operation presents severe kickback and cutting hazards that demand mandatory personal protective equipment (PPE).
Regular chain sharpening and bar lubrication maintain cutting speed and extend engine life.
- Personal protective equipment: Wear chainsaw protective chaps, safety helmet with face mesh shield, ear muffs, heavy leather gloves, and steel-toe boots.
- Chain lubrication: Ensure the automatic oiler reservoir is filled with proper bar oil to prevent chain overheating and friction wear.
- Chain tensioning: Maintain proper chain tension; a loose chain can derail from the guide bar, while an over-tight chain strains the engine.
- Subsidy support: Agricultural power saws and pruning equipment are subsidized under the Sub-Mission on Agricultural Mechanization (SMAM) via agrimachinery.nic.in.
