3. Fill Oil Tank: Use STIHL chainsaw bar and chain oil.
4. Starting Procedure: Set master control lever to cold start position, pull starter rope until resistance is felt, then pull briskly.

CAUTION! Ensure chain brake is disengaged before starting. Keep hands away from chain at all times.

Controls and Components

Master Control Lever: Combines stop switch, choke, and throttle settings. Front Handle: Includes throttle trigger and throttle interlock. Rear Handle: Contains master control lever and starter grip.

Key Controls: Master Control Lever (Stop/Choke/Run), Throttle Trigger, Throttle Interlock, Chain Brake Lever, Decompression Valve, Chain Tensioner.

Operation: Set master control to cold start (choke) for cold engine, to warm start for warm engine. Push decompression valve before starting to reduce pull force. Engage chain brake by pushing lever forward; disengage by pulling back toward rear handle.

Operation Guide

Starting, cutting techniques, and shutdown procedures.

1. Starting: Engage chain brake. Set master control to cold/warm start. Push decompression valve. Pull starter rope until engine fires. Move master control to run position. Pull starter rope again to start.
2. Cutting: Use full throttle when cutting. Let chain do the work; do not force. Be aware of kickback zone (upper quadrant of bar tip).
3. Shutdown: Release throttle, allow engine to idle. Move master control to stop position.

Tip: Always cut at waist level or below for better control. Plan escape path from falling tree or limb.

Maintenance Schedule

Daily and periodic maintenance tasks for optimal performance.

1. Daily: Check chain tension, sharpness, and lubrication. Clean air filter. Inspect guide bar for wear.
2. Weekly: Clean spark arrestor screen. Check fuel filter and replace if clogged.
3. Monthly: Check spark plug gap (0.020" / 0.5 mm). Clean cooling fins. Inspect anti-vibration elements.
4. As Needed: Replace worn sprocket, chain, or bar. Clean carburetor and fuel tank.

WARNING! Perform maintenance only when engine is off and cool. Disconnect spark plug wire for safety.

Chain & Bar Care

Proper chain tension, sharpening, and bar maintenance.

Chain Tension: Adjust when chain sags from bar rails. Correct tension allows chain to be pulled around bar by hand without binding. Sharpening: Use round file matching chain pitch (typically 5/32" or 7/32"). Maintain correct filing angle (usually 30°). Bar Maintenance: Clean bar groove regularly, flip bar periodically for even wear, and file down burrs on rails.

Fuel & Lubrication

Use fresh unleaded gasoline (min. 89 octane) mixed with STIHL 2-cycle engine oil at 50:1 ratio. Shake mixture well before refueling. For bar and chain oil, use STIHL or equivalent high-quality chainsaw oil. Do not use waste oil.

CAUTION! Store fuel mix in approved container for up to 30 days. Do not mix directly in saw's fuel tank.

Storage Instructions

For long-term storage (over 30 days), drain fuel tank and run engine until it stops to clear carburetor. Remove chain, clean, and store in oil. Clean entire saw and store in dry, cool place.

CAUTION! Storing with fuel in tank can cause carburetor damage from fuel deterioration.
