- Close-fitting clothing
- Hard hat (when working under trees)
Critical Safety Rules
- Keep Work Area Clean: Cluttered areas invite accidents. Ensure proper footing and balance at all times.
- Guard Against Electric Shock: Avoid body contact with grounded surfaces. Do not expose to rain or moisture.
- Keep Bystanders Away: All bystanders, children, and pets should be kept at least 15 meters away from work area.
- Use Right Tool: Do not force tool or use for purpose not intended. Use chainsaw only for cutting wood.
- Proper Grip: Maintain secure footing and grip chainsaw firmly with both hands when motor is running.
- Chain Brake Check: Test chain brake before each use by rotating bar tip into solid wood at idle speed.
- Kickback Awareness: Be aware of kickback zone (upper quadrant of bar tip). Never cut with this area.

Assembly Guide
Tools Needed:
- Hex wrench (provided)
- Screwdriver (flat head)
- Chain tensioning tool (provided)
- Bar nut wrench (provided)
- Safety gloves
Step-by-Step Assembly
- Unpack and Inspect: Remove all packaging materials. Verify all parts are included and undamaged.
- Attach Guide Bar: Place guide bar onto mounting studs. Ensure bar adjustment pin engages in bar hole.
- Install Chain: Place chain onto bar with cutting teeth facing forward on top of bar. Ensure drive links engage in bar groove.
- Secure Bar and Chain: Install bar cover plate and hand-tighten bar nuts. Do not fully tighten at this stage.
- Tension Chain: Use tensioning screw to adjust chain tension. Proper tension allows chain to be pulled away from bar about 1/8 inch.
- Final Tightening: Tighten bar nuts securely while maintaining chain tension. Recheck tension after tightening.
- Fill Oil Reservoir: Fill with recommended bar and chain oil. Check for leaks and proper oil flow to bar.
- Electrical Check: Ensure power cord is undamaged. Plug into appropriate GFCI protected outlet.
Operation Guide
Starting Procedure
Place chainsaw on clear, level surface. Hold rear handle with right hand, front handle with left hand. Depress safety trigger, then squeeze throttle trigger to start.
Proper Cutting Technique
Always cut at full throttle. Let chain do the work - don't force it. Maintain secure footing and be aware of kickback zone. Cut only wood - never metal, stone, or masonry.
Chain Brake Operation
Chain brake activates automatically during kickback or manually by pushing brake handle forward. Always test brake before use by rotating bar tip into solid wood at idle.
Oil System Check
Automatic oiling system lubricates chain during operation. Check oil flow by running chainsaw at full throttle near light-colored surface - oil should appear as fine spray.
Kickback Prevention
Never cut with upper quadrant of bar tip. Always hold chainsaw securely with both hands. Use reduced-kickback chain and low-kickback bar as provided.
Proper Stance & Grip
Stand with feet shoulder-width apart, left foot slightly forward. Grip handles firmly with thumbs wrapped around. Keep body to left of cutting plane.
Cutting Techniques
Felling Trees
Make notch cut 1/3 into tree on falling side, then back cut 2 inches above notch. Always have escape path planned.
Limbing
Cut limbs from bottom side when possible. Support large limbs. Be aware of spring poles and tension in wood.
Bucking Logs
Support log properly. Cut from top down, avoiding contact with ground. Roll log with cant hook when needed.
Pruning
Use light touch for small branches. Make relief cuts for larger limbs to prevent bark tearing.
Plunge Cutting
Advanced technique for notching. Begin with tip, gradually lowering bar into wood. Use extreme caution.
Cutting Firewood
Use sawhorses or log stands. Cut to consistent lengths. Keep work area clear of debris.
Maintenance
| Maintenance Task | Frequency | Procedure |
|---|---|---|
| Chain Sharpening | Every 2-3 hours of use | Use round file and guide. Maintain 30° top plate angle. All cutters must be same length. |
| Chain Tension Check | Before each use | Chain should snap back when pulled from bar. Adjust tension when chain sags from bar. |
| Bar Maintenance | Weekly | Clean bar groove. Flip bar regularly for even wear. Dress bar rails if burred. |
| Air Filter Cleaning | Monthly | Remove filter, tap clean. Wash in soapy water if very dirty. Dry completely before reinstalling. |
| Sprocket Inspection | Every 6 months | Check for wear. Replace if teeth are hooked or worn unevenly. Lubricate regularly. |
| Oil System Check | Before each use | Verify oil flow. Clean oil ports. Use only recommended bar and chain oil. |
| Brush Inspection | Annually | Have qualified technician inspect motor brushes. Replace if worn to 1/4 inch. |
| Overall Inspection | Seasonally | Check all nuts, bolts, and fasteners. Inspect power cord for damage. Test safety features. |
Sharpening Guide
- File Size: Use 5/32" round file for 3/8" pitch chain
- Angle: Maintain 30° top plate cutting angle
- Depth Gauges: File depth gauges with flat file after every 3-4 sharpenings
- File Holder: Use filing guide to maintain consistent angle
- Direction: File from inside to outside, applying even pressure
- Equal Length: Ensure all cutters are filed to same length for smooth operation
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Chainsaw won't start | No power, safety lock engaged, carbon brushes worn | Check power source, depress safety lock, inspect/replace brushes |
| Chain doesn't turn | Chain brake engaged, chain too tight, sprocket worn | Disengage brake, adjust tension, replace sprocket if needed |
| Poor cutting performance | Dull chain, improper filing, worn bar | Sharpen chain, check filing angle, inspect/replace bar |
| Chain throws oil | Overfilled oil tank, wrong oil viscosity | Drain excess oil, use proper bar and chain oil |
| Excessive vibration | Unbalanced chain, loose components, bent bar | Sharpen chain evenly, tighten all fasteners, replace bent bar |
| Motor overheats | Dull chain, forcing cut, inadequate ventilation | Sharpen chain, let tool work at own pace, clean air vents |
| Oil not reaching chain | Empty oil tank, clogged oil ports, faulty oil pump | Fill oil tank, clean oil ports, have pump serviced |
| Chain comes off bar | Loose chain, worn bar, damaged drive links | Adjust tension, replace bar if worn, replace damaged chain |
Common Error Indicators
- No Power: Check GFCI outlet, extension cord rating, circuit breaker
- Intermittent Operation: Inspect power cord for damage, check brush wear
- Excessive Sparking: Have commutator serviced by qualified technician
- Burnt Smell: Stop immediately - motor may be overheating or overloaded
- Unusual Noise: Check for loose components, worn bearings, damaged gears
- Chain Stops During Cut: Chain may be dull, tension too tight, or motor overloaded
