Read and understand all safety warnings before operation. Always wear appropriate PPE.
WARNING! Failure to follow safety instructions can result in serious injury or death. Never operate a chainsaw while fatigued or under the influence.
Unpack and inspect contents. Assemble guide bar and chain.
CAUTION! Ensure chain is correctly installed and tensioned before starting. A loose chain can derail; an overtightened chain can damage the engine.
Familiarize yourself with all controls before starting.
Main Controls: Master Control Lever (combines choke, stop switch, and start positions), Throttle Trigger, Throttle Trigger Lockout, Chain Brake Lever (front hand guard), Decompression Valve Button, Primer Bulb (if equipped).
Components: Fuel Tank Cap, Chain Oil Tank Cap, Spark Plug, Air Filter Cover, Muffler, Chain Catcher, Rear Hand Guard, Anti-Vibration Springs.
Adjustments: Chain Tensioning Screw, Idle Speed Screw (LA), High (H) and Low (L) Carburetor Adjustment Screws, Oil Pump Adjuster Screw.
Cold Start Procedure:
Warm Start: Set Master Control Lever to half-throttle position and pull starter.
Stopping: Release throttle, allow engine to idle briefly. Move Master Control Lever to STOP (0) position.
Proper technique is critical for safety and efficiency.
WARNING! Always be prepared for kickback. Never cut with the tip of the bar. Never operate above shoulder height.
| Interval | Task |
|---|---|
| Before each use | Check chain tension, sharpness, and lubrication. Inspect for loose parts. Check fuel/oil levels. |
| Every 5 hours | Clean air filter. Check spark plug condition. |
| Every 10 hours | Clean cooling fins. Check chain brake function. Clean exterior of saw. |
| Every 20 hours | Clean spark arrestor screen in muffler. Inspect fuel filter. |
| Every season | Replace fuel filter. Inspect anti-vibration elements. Check all nuts and bolts for tightness. |
| As needed | Sharpen chain. Replace worn bar. Replace worn sprocket. |
A sharp, properly tensioned chain is essential.
Sharpening: Use correct round file size (typically 4.0mm or 5/32" for .325" chain). Maintain original filing angle (usually 30°). File all cutters to equal length. File depth gauges (rakers) with a flat file and gauge.
Tensioning: Chain should be snug against bar but pull freely by hand. Adjust with side tensioner screw when saw is cool. Re-check tension after first few minutes of operation.
Tip: Rotate bar regularly to ensure even wear.
Prepare saw for storage to prevent fuel system issues.
CAUTION! Never store saw with fuel in the tank for more than 30 days. Old fuel can gum up carburetor.
| Symptom | Possible Cause | Corrective Action |
|---|---|---|
| Engine will not start | No spark, old fuel, flooded engine, clogged air filter | Check spark plug; use fresh fuel; wait if flooded; clean/replace air filter. |
| Engine starts then dies | Clogged fuel filter, dirty carburetor, faulty ignition | Replace fuel filter; clean carburetor; check ignition coil gap. |
| Poor performance/lacks power | Dull chain, clogged spark arrestor, incorrect carb adjustment | Sharpen chain; clean spark arrestor screen; adjust H & L jets. |
| Chain does not oil | Empty oil tank, clogged oil passages, faulty oil pump | Fill tank; clean bar oil holes and tank vent; check pump drive. |
| Excessive vibration | Loose components, worn AV mounts, unbalanced chain | Tighten all nuts/bolts; inspect AV springs; balance chain by sharpening evenly. |
| Chain throws off bar | Loose chain, worn bar rails, damaged drive sprocket | Tension chain properly; inspect bar for wear; replace sprocket if worn. |
