Starting & Operation

Cold Start Procedure:

1. Place on clear, level surface.
2. Engage chain brake.
3. Set stop switch to "I" (run).
4. Push decompression valve.
5. Full choke, press primer bulb 5-6 times.
6. Pull starter rope until engine fires (1-3 pulls).
7. Move choke to half position, pull until starts.
8. Disengage chain brake before cutting.

Tip: Always warm up engine for 30 seconds before cutting.

Maintenance Schedule

Daily: Check chain tension, sharpness, lubrication. Clean air filter, check for loose fasteners.

Weekly: Clean spark arrestor screen, check spark plug gap (0.025 in), clean cooling fins.

Monthly: Clean fuel filter, replace air filter if needed, check anti-vibration mounts.

Seasonally: Replace spark plug, clean carburetor, inspect fuel lines.

WARNING! Always disconnect spark plug wire before performing maintenance.

Chain Sharpening & Tensioning

Sharpening: Use round file matching chain pitch (.325"). Maintain 30° top plate angle, 10° down angle.

1. Secure bar in vise.
2. File from inside out, maintaining consistent angle.
3. File all cutters to same length.
4. File depth gauges with flat file.

Tensioning: Chain should snap back when pulled from bar. Adjust with side-access tensioner while lifting bar tip.

CAUTION! Over-tightening can damage bar and chain. Chain should move freely when cool.

Storage

Long-term storage procedure:

1. Drain fuel tank and run engine until carburetor is dry.
2. Remove chain, clean and soak in oil.
3. Clean entire saw, especially cooling fins.
4. Store in dry place, cover to prevent dust.

WARNING! Never store with fuel in tank for more than 30 days.
