Chainsaw Safety Fundamentals

Essential safety rules every arborist must follow when operating chainsaws.

Rule	Description
Maintain Secure Footing	Always stand on stable ground with proper balance
Keep Both Hands on Handles	Grip front and rear handles firmly during operation
Be Aware of Kickback Zone	Avoid contact with upper quadrant of guide bar tip
Clear Work Area	Remove debris, tripping hazards, and ensure escape path
Never Cut Above Shoulder Height	Maintain control by keeping cuts at or below chest level
Watch for Tension & Compression	Identify wood stress patterns before cutting
Shut Off During Transport	Engage chain brake and turn off when moving between cuts
No Solo Work	Always have another trained person within calling distance
Respect Fatigue	Take regular breaks to maintain concentration
Follow Manufacturer Guidelines	Adhere to specific model recommendations and limits

Personal Protective Equipment (PPE)

Mandatory protective gear for chainsaw operation in arboriculture.

Chainsaw Protective Chaps/Pants: CE-certified with ballistic fibers.
Safety Helmet: Integrated hearing protection and face shield.
Eye Protection: Safety glasses or visor for debris protection.
Gloves: Cut-resistant with good grip and dexterity.
Steel-Toe Boots: With chainsaw protection and slip-resistant soles.
High-Visibility Vest: For visibility in work zones.

WARNING! Never operate a chainsaw without full PPE. Inspect equipment before each use for damage.

Chainsaw Components & Terminology

Key parts and technical terms arborists need to know.

Guide Bar: Length determines cutting capacity (14-24 inches common).
Chain: Cutting teeth configuration (chipper, semi-chisel, full-chisel).
Powerhead: Engine (gas) or motor (electric) unit.
Chain Brake: Manual/automatic safety stop mechanism.
Throttle Trigger: Controls engine speed and chain movement.
Chain Tensioner: Adjusts chain tightness on guide bar.
Oil Reservoir: Holds bar and chain lubrication oil.
Carburetor: Mixes air and fuel in gas models.
Spark Arrestor: Prevents emission of burning particles.
Anti-Vibration System: Reduces operator fatigue.

CAUTION! Understand all controls before operation. Refer to specific model manual.

Pre-Operation Inspection

Chain Sharpness: Check teeth for proper filing angle and depth gauges.
Chain Tension: Should snap back when pulled from guide bar.
Guide Bar: Inspect for straightness, groove wear, and lubrication holes.
Bar & Chain Oil: Verify adequate level and flow to bar tip.
Fuel/Oil Leaks: Check for leaks from tank, lines, and connections.
Air Filter: Clean or replace if clogged for proper airflow.
Spark Plug: Check condition and gap specification.
Controls & Safety Features: Test throttle, choke, chain brake, and kill switch.
Fasteners: Ensure all nuts, bolts, and screws are tight.
Chain Catcher: Verify it's intact and properly positioned.

Starting Procedures

Proper starting techniques for gas and electric chainsaws.

Gas Models: Place on clear ground, engage chain brake, set choke, pull starter cord smoothly. Electric Models: Verify power source, ensure switch is off before plugging in, use GFCI outlets.

Cold Start: Full choke, prime if equipped, pull until engine fires, then half choke. Warm Start: No choke, slight throttle, pull starter. Drop Starting: NEVER attempt - always place saw on ground. Position body to side of cutting plane during starting.

Basic Cutting Techniques

Fundamental cuts for arborist work: felling, limbing, bucking, and pruning.

Plan each cut considering tree lean, wind, and escape routes.
Use proper stance: feet shoulder-width, knees slightly bent.
Let the saw do the work - avoid forcing or twisting.
For felling: notch cut (open face or conventional), then back cut.
For bucking: support log properly, cut from top, watch for binding.
For limbing: work from trunk outward, beware of spring poles.
For pruning: identify branch collar, make clean cuts outside collar.

Tip: Keep chain sharp - a sharp chain requires less force and produces less kickback risk.

Maintenance & Sharpening

Regular maintenance schedule for professional chainsaw care.

Daily: Clean air filter, check chain tension, refuel and oil.
Weekly: Clean cooling fins, check spark plug, inspect bar groove.
Monthly: Clean carburetor air filter, check fuel filter, inspect anti-vibration mounts.
Sharpening: File at correct angle (25-35°), maintain consistent depth gauge height.
Chain Rotation: Rotate bar regularly to ensure even wear.
Lubrication: Use proper bar and chain oil (tackifier additives for professional use).
Storage: Drain fuel for long-term storage, run carburetor dry.
Professional Service: Annual tune-up including compression test and carb adjustment.

WARNING! Always disconnect spark plug before performing maintenance. Use proper tools.

Common Chainsaw Models

Popular chainsaw brands and models used in arboriculture.

Brand	Professional Models	Key Features

Troubleshooting Guide

Symptom	Possible Cause	Corrective Action
Won't start	Fuel issues, spark plug, flooded engine	Check fuel mix, clean spark plug, wait if flooded
Runs then dies	Clogged filter, carb adjustment	Clean air/fuel filters, adjust carburetor
Poor cutting performance	Dull chain, wrong filing angle	Sharpen properly, check depth gauges
Chain won't stay tight	Worn bar, stretched chain	Inspect bar groove, replace chain if stretched
Excessive vibration	Loose components, worn AV mounts	Tighten fasteners, replace anti-vibration elements
Chain throws oil	Overfilling, wrong oil viscosity	Check oil level, use proper bar oil
Overheating	Dull chain, clogged cooling fins	Sharpen chain, clean cooling system
Chain doesn't turn	Clutch issues, drive sprocket	Inspect clutch springs, check sprocket wear

Storage & Transportation

Proper chainsaw storage and transport protocols for arborists.

Clean thoroughly before storage - remove sawdust, resin, and debris.
For gas models: Run carburetor dry or add fuel stabilizer.
Remove chain, clean and oil it separately.
Store in dry, secure location away from children.
Transport in protective case with bar guard installed.
Secure in vehicle to prevent movement during transit.
Keep fuel containers separate from saw storage area.
Label storage containers clearly with contents and hazards.

CAUTION! Never transport chainsaw with fuel in tank inside enclosed vehicle passenger area.

Arborist-Specific Applications

Specialized chainsaw techniques for tree care professionals.

Climbing Saws: Lightweight, compact models for aerial work.
Notching Techniques: Open-face, Humboldt, and conventional notches.
Bore Cutting: For controlling hinge wood and preventing barber chairs.
Top Handle Saws: Specialized for one-handed operation (trained use only).
Rigging Cuts: Techniques for controlled lowering of limbs and sections.
Root Cutting: Specialized bars and chains for below-ground work.
Portable Mill Attachments: For on-site lumber production.
Pole Saws: Extended reach for pruning without climbing.

Professional Training: Always seek certified training for advanced techniques. Contact International Society of Arboriculture (ISA) or Tree Care Industry Association (TCIA) for courses.
