Installation Guide
Tools Needed:
- Chain tensioning screwdriver
- Socket wrench set
- Bar and chain oil
- Fuel mixing container
- Safety gloves and goggles
Step-by-Step Assembly
- Unpack and Inspect: Remove all packaging materials and inspect components for damage during shipping.
- Handle Assembly: Attach the front and rear handles according to the provided diagram, ensuring all bolts are tightened securely.
- Bar and Chain Installation: Mount the guide bar and fit the chain, ensuring proper direction and tension.
- Chain Tension Adjustment: Adjust chain tension using the side-mounted tensioning screw - proper tension allows chain to move freely without sagging.
- Fuel and Oil Preparation: Mix 2-stroke engine oil with unleaded gasoline at 50:1 ratio. Fill bar and chain oil reservoir.
- Safety Check: Verify chain brake operation, throttle lockout function, and all safety features before starting.
- Initial Start-up: Follow cold start procedure: set choke, prime fuel bulb, pull starter cord until engine fires.

Key Features
X-Torq® Engine Technology
Reduces fuel consumption and exhaust emissions while maintaining high power output. Provides cleaner combustion and better fuel economy.
LowVib® Anti-Vibration System
Advanced dampeners between the engine unit and handles significantly reduce vibration levels, decreasing operator fatigue during extended use.
Smart Start® System
Reduces resistance in the starter cord by up to 40% for easier starting. Combined with automatic decompression valve for quick, reliable starts.
Air Injection™ Centrifugal Cleaning
Centrifugal force removes larger dust and debris particles before reaching the air filter, extending filter life and reducing maintenance frequency.
Combined Choke/Stop Control
Single-lever control for choke, run, and stop positions simplifies operation and prevents engine flooding during starting.
Inertia Activated Chain Brake
Front hand guard activates chain brake in kickback situations, stopping the chain within milliseconds for enhanced operator safety.
Safety Systems Explained
Chain Brake
Stops chain rotation within 0.15 seconds when activated manually or by inertia during kickback
Throttle Lockout
Prevents accidental throttle operation; must be depressed before throttle trigger can be engaged
Right Hand Guard
Protects right hand from chain contact and activates inertia chain brake during kickback
Vibration Dampening
Rubber dampeners isolate handles from engine vibration, reducing operator fatigue
Chain Catcher
Prevents broken chain from striking the operator in case of chain breakage
Exhaust Deflection
Directs exhaust gases away from operator during cutting operations
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Engine won't start | Old fuel, clogged air filter, spark plug issue | Use fresh fuel mix, clean/replace air filter, check spark plug |
| Engine starts then dies | Fuel line blockage, carburetor adjustment, vent issue | Clean fuel system, adjust carburetor, check tank vent |
| Poor cutting performance | Dull chain, improper tension, worn bar | Sharpen chain, adjust tension, inspect/replace bar |
| Chain won't stay lubricated | Empty oil tank, clogged oil ports, wrong oil viscosity | Fill oil tank, clean oil ports, use correct bar oil |
| Excessive vibration | Loose components, unbalanced chain, worn dampeners | Tighten all bolts, balance chain, replace dampeners |
| Chain throws off bar | Worn drive sprocket, damaged bar rails, improper tension | Replace sprocket, repair/replace bar, adjust tension |
Maintenance Schedule
- Daily: Check chain tension, sharpness, and lubrication
- Weekly: Clean air filter, check spark plug, inspect bar wear
- Monthly: Clean cooling fins, check fuel filter, inspect anti-vibration elements
- Seasonally: Replace spark plug, clean carburetor, check all safety features
- Annually: Professional servicing recommended for heavy users
