Components: Muffler, spark plug, air filter, fuel cap, oil cap, chain tensioner knob, chain catcher, and hand guard.

Operation: Set choke for cold start, press primer bulb 5-6 times, pull starter cord. Use throttle lockout with throttle trigger for operation. Engage chain brake by pushing hand guard forward.

Operation

Starting Procedure (Cold Engine):

1. Place saw on flat ground, clear of debris.
2. Engage chain brake.
3. Set choke to full position.
4. Press primer bulb until fuel is visible.
5. Pull starter cord sharply until engine fires (1-3 pulls).
6. Move choke to half position, pull until engine starts.
7. Allow to warm up at idle for 30 seconds, disengage chain brake.

Cutting Techniques: Use lower quadrant of bar for cutting. Let saw do the work; do not force. For felling, plan escape path, make notch cut, then felling cut.

Chain & Bar Maintenance

Regular maintenance ensures optimal performance and safety.

1. Chain Sharpening: Use round file (5/32") and file guide. Maintain 30° cutting angle. Sharpen when saw produces fine dust instead of chips.
2. Chain Tension: Check frequently when hot and cold. Proper tension: snug against bar but pullable by hand.
3. Bar Maintenance: Clean bar groove, flip bar monthly for even wear, check for wear and straightness.
4. Oiler Check: Ensure oiler port is clear; adjust flow rate if equipped.

Tip: Keep chain out of dirt and sand to prolong sharpness.

Engine Maintenance

Follow maintenance schedule for reliable operation.

CAUTION! Disconnect spark plug wire before performing maintenance.

Storage

Prepare chainsaw for storage if not used for 30+ days.

1. Drain fuel tank and run engine until it stops to empty carburetor.
2. Remove spark plug, add 1 teaspoon of oil through spark plug hole, pull starter cord slowly to distribute, reinstall plug.
3. Clean entire saw, remove debris from cooling fins.
4. Loosen chain tension, store in dry place.

WARNING! Never store with fuel in tank for extended periods; fuel can degrade and damage components.
