Kickback Prevention

Understanding Kickback Hazards

Kickbacks are sudden and violent. Improper setup increases risk. Avoid ground contact.

Grip and Basic Prevention Rules

Firm grip with thumbs and fingers. Know kickback causes to reduce surprise.

Advanced Kickback Prevention

Safe Limbing and Cutting Methods

Be careful during limbing. Avoid cutting above shoulder height. Maintain full speed.

Equipment and Maintenance for Safety

Use recommended combinations, smaller bar radius reduces kickback. Follow maintenance.

Chain Brake System Operation

Chain Brake Activation Methods

Manual and inertia activation of the chain brake. Slip clutch protects against overload.

Kickback Guard and Parking Brake Use

Purpose of kickback guard. Use chain brake as parking brake. Release brake by pulling guard back.

Kickback Response and Grip

Maintain firm grip. Chain brake activation depends on kickback strength and saw position.

Chain Brake System Checks

Brake Band and Kickback Guard Inspection

Clean debris from brake band and clutch drum. Inspect guard for defects and free movement.

Manual and Inertia Brake Function Tests

Test manual activation by twisting wrist. Test inertia activation by dropping saw onto stump.

Saw Safety Features

Chain Catcher Function

Designed to catch broken or derailed chains. Ensure it is undamaged.

Right Handguard Protection

Protects right hand and prevents interference from debris during operation.

Slip Clutch and Overload Protection

Slip clutch protects from overload. Electronic protection stops saw when tripped.

Mounting Guide Bar and Adjusting Chain

Safety and Preparation Steps

Always wear gloves. Ensure chain is properly tensioned to prevent derailment.

Chain and Guide Bar Installation

Steps for mounting the guide bar and fitting the chain around the drive sprocket.

Chain Tensioning Procedure

Tension chain using screw until slack is gone but chain moves freely by hand.

New Chain Break-in and Tensioning

Check new chain tension frequently during break-in. Regular tensioning compensates for wear.

Cutting Equipment Best Practices

Benefits of Proper Equipment Use

Reduces kickback, derailing, and breakage. Achieves maximum cutting effect and chain life.

Five Basic Rules for Cutting Equipment

Use recommended equipment, ensure sharp cutters, maintain depth-gauge height.

Chain Tensioning and Lubrication Checks

Keep chain tensioned properly. Ensure automatic oiling system is functioning.

Chain and Guide Bar Lubrication

Lubrication System and Oil Recommendations

Automatic oiling. Use specific chain oil, consider viscosity. Avoid old motor oil.

Checking Automatic Lubrication

Start saw and check for oil spatter. Full reservoir lasts approximately 20 minutes.

Lubrication Troubleshooting

Check oil passage, guide bar groove, and nose sprocket if system seems faulty.

Checking Chain and Sprocket Wear

Chain Wear Inspection Criteria

Inspect for cracks, stiffness, wear, cutter length. Discard worn chains.

Drive Sprocket Wear Check

Regularly check drive sprocket wear and replace if it becomes excessive.

Starting and Stopping the Saw

Safe Starting Procedure

Secure footing, grip handles firmly, engage lockout button and trigger.

Safe Stopping Procedure

Release power trigger. If saw doesn't stop, use chain brake and disconnect power.

Chain Filing and Sharpening

Identifying Dull Chains and Cutters

Dull chains need more pressure, produce small chips. Improper filing increases kickback.

Filing Angles and Aids

Pay attention to top-plate, cutting, and horizontal file angles. Use file guides for efficiency.

Filing Techniques and Cutter Length

File from inside out, lift file on return. Ensure cutters are equal length. Discard worn chains.

Crosscutting Techniques

Cutting Logs on the Ground

Saw straight through, be careful of ground contact at breakthrough.

Cutting Supported Logs

For one-end support, cut 2/3 through then from top. For two-end support, start top then bottom.

Limbing Branches Safely

Limbing Safety and Kickback Caution

Most kickbacks occur during limbing. Pay attention to kickback danger zone on tensioned limbs.

Limbing Techniques and Footing

Apply crosscutting principles. Cut complicated branches in stages. Ensure secure footing.
