Assembly Instructions

Unpack and inspect all components before assembly.

1. Attach guide bar: Place bar on mounting studs, align chain with sprocket, install bar nuts finger-tight.
2. Install chain: Ensure cutting teeth face forward on top of bar, adjust tension with side cover screws.
3. Fill oil reservoir: Use recommended bar and chain oil, check for leaks.
4. Mix fuel: 50:1 gasoline to 2-stroke oil ratio, shake well before filling.
5. Check controls: Verify throttle trigger, chain brake, and safety switches function properly.

CAUTION! Always wear gloves when handling chain. Ensure chain is properly seated on bar sprocket.

Starting Procedure

Follow cold start procedure for initial start, warm start for hot engine.

1. Cold Start: Place on flat surface, engage chain brake, set master control to choke, pull starter rope 3-4 times until engine fires.
2. Warm Start: Set master control to run position, pull starter rope 1-2 times.
3. After Starting: Disengage chain brake, allow 30-second warm-up before cutting.
4. Stopping: Release throttle, press stop switch to OFF position.

Tip: Always engage chain brake when starting. Never drop start chainsaw.

Cutting Techniques

Proper technique ensures safety and efficiency.

1. Felling: Plan escape path, make notch cut 1/3 diameter, make felling cut leaving hinge.
2. Limbing: Work from trunk to top, cut from opposite side of log.
3. Bucking: Support log properly, cut from top down for tension wood, bottom up for compression.
4. Pruning: Cut small branches with pulling chain, larger branches with proper support.
5. Kickback Prevention: Maintain firm grip, avoid upper quadrant of bar tip, use reduced-kickback chain.

WARNING! Beware of kickback zone (upper quadrant of bar tip). Always cut at full throttle.

Maintenance Schedule

Regular maintenance ensures optimal performance and longevity.

Interval	Maintenance Task
Daily	Check chain tension, sharpness, bar oil level, air filter
Weekly	Clean spark arrestor, check spark plug, clean cooling fins
Monthly	Clean fuel filter, check fuel lines, lubricate clutch bearing
Seasonally	Replace air filter, spark plug, clean carburetor
Annually	Check piston/cylinder, replace fuel filter, professional tune-up

CAUTION! Always disconnect spark plug wire before performing maintenance.

Chain Sharpening

Sharp chain improves cutting efficiency and safety.

1. File Size: Use 5/32 inch (4.0mm) round file for 3/8 pitch chain.
2. Filing Angle: Maintain 30-degree angle for cutting teeth.
3. Depth Gauges: File to 0.025 inch (0.65mm) below cutting tooth.
4. Procedure: Secure bar, file from inside to outside, equal strokes per tooth.
5. Check: All teeth equal length, depth gauges properly set, file rakers as needed.

Tip: Sharpen chain when saw produces fine dust instead of chips. Rotate file regularly.

Storage Guidelines

Proper storage prevents fuel system issues and corrosion.

1. Short-term (under 30 days): Fill fuel tank, add fuel stabilizer, run 2 minutes.
2. Long-term (over 30 days): Drain fuel completely, run until dry, remove spark plug, add oil to cylinder.
3. Chain Storage: Clean and oil chain, store in sealed container.
4. General: Clean entire saw, store in dry place, cover to prevent dust.

CAUTION! Never store with fuel in tank for extended periods without stabilizer.

Troubleshooting

Symptom	Possible Cause	Corrective Action
Engine won't start	No spark, fuel issues, flooded	Check spark plug, fuel quality, use decompression valve if flooded
Engine runs poorly	Dirty air filter, carburetor issues	Clean/replace air filter, adjust carburetor screws
Chain doesn't turn	Clutch issues, chain brake engaged	Disengage chain brake, check clutch springs and drum
Excessive vibration	Loose components, unbalanced chain	Tighten all fasteners, balance chain by sharpening evenly
Chain won't stay sharp	Hitting ground, dirty wood	Avoid cutting into dirt, clean wood before cutting
Oil not pumping	Clogged oil passages, pump failure	Clean oil passages, check pump drive mechanism
