Assembly & Preparation

Unpack and inspect all parts. Assemble on a clean, stable surface.

  1. Attach Guide Bar and Chain: Place bar on studs, adjust tension, fit chain with cutters facing forward, tighten nuts.
  2. Fill Fuel Tank: Use clean, fresh gasoline mixed with high-quality 2-stroke oil at 50:1 ratio (STIHL HP Ultra recommended).
  3. Fill Chain Oil Tank: Use STIHL chain oil or equivalent for lubrication.
  4. Check Chain Tension: Chain should be snug against bar but pull freely by hand.

WARNING! Always wear protective gear: gloves, eye protection, hearing protection, chainsaw chaps, and sturdy boots. Never operate without proper training.

First-Time Operation

Before starting, ensure chain brake is engaged (pulled forward).

  1. Master Control Lever: Set to cold start position (choke).
  2. Decompression Valve: Press to reduce compression for easier starting.
  3. Starting Procedure: Place saw on ground, hold handle with foot, pull starter cord briskly until engine fires.
  4. Warm-Up: Move master control to fast idle, allow engine to warm for 30 seconds.
  5. Disengage Chain Brake: Pull back towards handle before cutting.

CAUTION! Keep bystanders and pets at least 15 feet away. Clear work area of debris. Plan escape path.

Specifications

Controls and Functions

Master Control Lever: Combines choke, throttle lock, and stop functions. Throttle Trigger: Controls engine speed. Throttle Trigger Lockout: Must be depressed to engage throttle. Chain Brake Lever: Stops chain instantly if activated manually or by kickback. Decompression Valve: Reduces compression for easier starting.

Operation Positions: Choke (cold start), Fast Idle (warm start), Run (normal operation), Stop (engine off).

Adjustments: Carburetor idle and high-speed screws (limit caps installed). Chain Tension: Adjust via side knob when bar nuts are loosened.

Chain & Bar Setup

Proper chain installation and tension are critical for safety and performance.

  1. Loosen bar nuts with combination wrench.
  2. Lift bar tip, adjust tensioning screw until chain fits snugly in bar groove.
  3. Chain should pull freely around bar by hand without sagging on bottom.
  4. Tighten bar nuts securely while holding bar tip up.
  5. Re-check tension after tightening; chain expands when warm.

Tip: Always stop engine and wear gloves when handling chain. Keep chain sharp and properly lubricated.

Cutting Techniques

Basic cutting methods for safe operation.

  1. Felling: Plan notch and back cut. Use wedges for larger trees. Always have escape route.
  2. Limbing: Work from trunk outward. Keep saw stable, avoid cutting with tip.
  3. Bucking: Support logs properly. Cut from top down, avoid pinching chain.
  4. Pruning: Use bottom of bar for control. Beware of springback on branches.

WARNING! Never cut above shoulder height. Avoid kickback by not contacting with upper tip of bar. Always use both hands.

Maintenance Schedule

Daily: Clean air filter, check chain tension and sharpness, inspect for loose parts. Weekly: Clean cooling fins, check spark plug, clean chain brake mechanism. Monthly: Clean fuel filter, replace air filter if needed, check anti-vibration elements. Seasonally: Replace spark plug, clean carburetor, inspect fuel lines.

Storage Guidelines

For long-term storage, empty fuel tank and run carburetor dry. Remove chain, clean and oil it. Store in dry place. Use fuel stabilizer if storing with fuel.

CAUTION! Store fuel in approved container away from heat sources. Keep saw out of reach of children.

Safety Information

Read manual completely before use. Wear all PPE. Never operate when tired or under influence. Keep firm grip, proper footing. Do not operate on ladders or unstable surfaces. Beware of kickback—maintain saw speed, use reduced-kickback chain. Chain brake must be tested before each use.
