Setup and Installation

Follow these steps to properly install the new bar and chain on your DOLMAR chainsaw.

1. Prepare the Chainsaw: Ensure the chainsaw is off, the spark plug cap is removed, and the chain brake is disengaged.
2. Remove Old Components: Loosen the bar nuts and remove the clutch cover. Carefully remove the old guide bar and chain.
3. Clean: Clean any sawdust or debris from the clutch area, bar groove, and oil holes.
4. Install New Chain: Place the new chain around the clutch sprocket, ensuring the cutting edges are facing the correct direction (usually forward on the top of the bar).
5. Install New Bar: Slide the guide bar studs through the holes in the new guide bar. Align the chain drive links with the bar groove.
6. Reinstall Clutch Cover: Replace the clutch cover, ensuring the chain tensioner pin engages with the hole in the guide bar. Hand-tighten the bar nuts.
7. Adjust Chain Tension: Using the chain tensioning screw, adjust the chain tension. The chain should be snug against the bottom of the bar, but still able to be pulled freely by hand. It should not sag underneath the bar.
8. Tighten Bar Nuts: Once tension is set, fully tighten the bar nuts.
9. Check Oil Flow: Before operation, ensure the oiler is functioning correctly and lubricating the bar and chain.

Operating Considerations

While this manual focuses on the bar and chain, proper chainsaw operation is critical for safety and performance.

• Always ensure the chain is properly tensioned before and during use. A loose chain can derail, and a too-tight chain can cause premature wear.
• Keep the chain sharp. A dull chain increases kickback risk and puts strain on the chainsaw engine.
• Ensure adequate chain lubrication by regularly checking the oil reservoir.

Maintenance

Regular maintenance extends the life of your bar and chain and ensures safe operation.

• Chain Sharpening: Sharpen the chain regularly using a round file appropriate for the chain pitch (3/8" LP). Maintain consistent angles on all cutters.
• Bar Maintenance:
  • Clean the bar groove regularly to remove sawdust and debris.
  • Flip the guide bar periodically to ensure even wear on both sides.
  • Check the nose sprocket for wear and ensure it spins freely.
  • Remove any burrs from the bar rails using a flat file.
• Lubrication: Ensure the chainsaw's automatic oiler is functioning correctly and providing sufficient lubrication to the bar and chain.
• Storage: When not in use, clean the bar and chain thoroughly and store in a dry place to prevent rust.
