Read and understand all instructions before use. Wear proper PPE.
WARNING! Chainsaws are dangerous tools. Failure to follow safety rules can result in serious injury or death.
Unpack and inspect contents. Assemble guide bar and chain.
CAUTION! Ensure chain brake is disengaged (pulled back toward front handle) before starting.
Familiarize yourself with all controls before starting.
Right Side: Throttle Trigger, Throttle Lockout (must be depressed to engage throttle), Front Hand Guard / Chain Brake, Stop Switch.
Left Side: Choke/Stop Control Lever (positions: RUN, CHOKE, STOP), Decompression Valve (if equipped), Primer Bulb (if equipped), Fuel Cap, Oil Cap.
Rear: Rear Handle, Starter Grip, Air Filter Cover, Spark Plug.
Chain Brake: Engages automatically via inertia or manually by pushing hand guard forward. Pull back toward front handle to disengage.
Cold Start Procedure:
Warm Start: Begin at step 3 with choke in RUN position.
Stopping: Release throttle, allow engine to idle. Move stop switch to STOP position or move choke control to STOP.
Tip: Maintain a sharp chain. A dull chain requires more force, increases wear, and is more dangerous.
| Interval | Task |
|---|---|
| Before each use | Check chain tension, sharpness, and lubrication. Check for loose nuts/bolts. Inspect for damage. |
| Daily (or every 5 hours) | Clean air filter. Check fuel filter in tank. |
| Weekly (or every 25 hours) | Clean cooling fins. Check spark plug condition/gap. Clean exterior of saw. |
| Monthly (or every 100 hours) | Replace spark plug. Clean fuel filter. Check/replace fuel line if cracked. |
| Seasonally | Clean/replace air filter. Check anti-vibration elements. Clean carburetor air intake. |
CAUTION! Always disconnect spark plug wire before performing maintenance.
Sharpening: Use a round file matching chain pitch (5/32" for 3/8" LP). File each cutter at original angle (typically 30°). Maintain equal length on all cutters. File depth gauges with a flat file and gauge.
Tensioning: Loosen bar nuts. Turn tensioning screw (located near bar mount) clockwise to tighten until chain is snug against bar but can be pulled around by hand. Tighten bar nuts. Re-check tension after first few cuts.
WARNING! A loose chain can derail. An overtightened chain can break and cause excessive wear.
CAUTION! Never store a chainsaw with fuel in the tank or carburetor. Fuel can degrade and cause starting problems.
| Symptom | Possible Cause | Corrective Action |
|---|---|---|
| Engine will not start | No spark, old fuel, flooded engine, clogged filter | Check spark plug. Use fresh fuel mix. Wait if flooded. Clean/replace air filter. |
| Engine starts then dies | Clogged fuel filter, dirty carburetor, faulty fuel line | Replace fuel filter. Clean carburetor. Inspect fuel line for cracks. |
| Engine lacks power | Dirty air filter, clogged spark arrestor, dull chain | Clean air filter. Clean spark arrestor screen. Sharpen chain. |
| Chain does not turn | Clutch worn, drive sprocket worn, chain brake engaged | Inspect clutch and sprocket. Disengage chain brake. |
| Chain throws oil but does not lubricate bar | Oil hole clogged, wrong oil viscosity | Clean oil outlet on bar and saw. Use proper chain oil. |
| Excessive vibration | Loose components, unbalanced chain, worn anti-vibration mounts | Tighten all nuts/bolts. Sharpen chain evenly. Check mounts. |
