Chainsaws

High Risk Equipment - Training Required

Chainsaws are extremely dangerous. Proper training is mandatory before use. Always wear full PPE. Read the complete manual for your specific saw before operating.

Available Chainsaws

Both chainsaws use 50:1 fuel mix (petrol:2-stroke oil).

Required PPE

Mandatory Safety Equipment

Most chainsaw accidents occur when the chain contacts the operator. PPE significantly reduces injury severity. No exceptions.

Critical Safety Rules

These rules apply to all chainsaw operation, regardless of model:

1. Never use with one hand - always maintain a firm two-handed grip
2. Never cut above shoulder height
3. Correct hand position: Right hand on rear/top handle, left hand on front handle (regardless of handedness)
4. Maintain firm footing at all times
5. Be aware of the kickback zone - the top quarter of the bar tip
6. Never cut with the tip of the bar
7. Engage chain brake when walking between cuts
8. Observe surroundings - check for people, animals, and hazards
9. Never operate when impaired - fatigue, alcohol, or medication
10. Maintain 15-meter safety distance from bystanders

Kickback Prevention

Kickback Warning

Kickback occurs when the chain at the bar tip catches an object, causing a lightning-fast reverse reaction that rotates the bar upward toward the operator. This is the most common cause of serious chainsaw injuries.

Prevent Kickback By:

• Never letting the bar tip contact anything - be aware of tip position at all times
• Keeping chain sharp and properly tensioned
• Not overreaching - maintain stable, balanced stance
• Using low-kickback chain if available
• Maintaining focus - lack of concentration is a major cause
• Never cutting with the upper quadrant of the bar tip

Reactive Forces

Be aware of these forces when cutting:

Always anticipate these forces and maintain a secure grip and stance.

Emergency Procedures

Kickback Injury

1. Stop the chainsaw immediately
2. Apply direct pressure to wound / call for help
3. Seek medical attention - chainsaw wounds are always serious
4. Do not remove embedded objects

Fire

• Keep fire extinguisher nearby during all operation
• Hot muffler and sparks can ignite dry materials
• Clear work area of dry leaves and debris
• If clothing catches fire: STOP, DROP, ROLL

Chain Jams in Cut

1. Stop the engine immediately
2. Never try to free the bar while engine is running
3. Use a wedge or lever to open the cut and free the bar
4. Check chain and bar for damage before restarting

Carbon Monoxide

• Never operate indoors or in enclosed spaces
• Exhaust fumes are toxic and can be fatal
• If feeling dizzy or nauseous, move to fresh air immediately

Fuelling

Fuel Safety

• Never refuel while engine is running or hot
• Use approved fuel containers only
• No smoking or open flames nearby
• Wipe up any spills before starting
• Refuel outdoors only

Fuel Mix

Both chainsaws use 50:1 ratio (2% oil):

Fuel Freshness

Only mix enough fuel for 30 days of use. Stale fuel causes starting problems and engine damage.

Chain Oil

Use quality bar and chain oil. Check oil level before each use - the chain requires constant lubrication during operation.

Chain Maintenance

Signs of a Dull Chain

Sharpening Basics

• Use correct round file size for your chain
• File from inside of cutting tooth outward
• Maintain correct filing angle (check manual)
• Keep all teeth the same length
• Adjust depth gauges after every 3rd sharpening

Sharpening Affects Safety

Incorrect sharpening significantly increases kickback risk. If unsure, have chain professionally sharpened or replaced.

Chain Tension

Correct tension: chain can be pulled slightly away from bar (~3mm) but snaps back into the groove.

• Too loose: Chain can derail or whip
• Too tight: Excessive wear, can break

Check tension frequently - new chains stretch quickly.

Storage

Short-term Storage

• Engage chain brake
• Clean saw body and bar
• Store in dry location away from direct sunlight
• Use bar cover/scabbard if available

Long-term Storage (Over 3 Months)

1. Run engine until fuel tank is empty (prevents fuel system damage)
2. Remove and clean chain and guide bar
3. Apply light oil to chain to prevent rust
4. Clean the entire saw
5. Store in dry location

Storage Location

TBD - Add chainsaw storage location
