EGO Power+ 16" Replacement Chainsaw Chain for CS1600/CS1604 — AC1600 .043" Gauge, 3/8" Low Pro Pitch

The EGO POWER+ AC1600 16-inch replacement chain is the factory-compatible, low-kickback chain designed specifically for the EGO POWER+ CS1600 and CS1604 electric chainsaws.

If you own an EGO 16-inch electric chainsaw, fitting the correct replacement chain matters for safe, reliable cutting and optimal performance. The AC1600 chain was engineered to match the CS1600-series saws' bar and sprocket geometry, offering the correct .043 in. gauge and 3/8 in. Low Pro pitch so the chain tracks and tensions properly. Choosing a genuine EGO part avoids fitment issues and maintains the cutting behavior you expect from your saw.

Will this chain fit my EGO CS1600 or CS1604 chainsaw?

Yes — the AC1600 is manufactured to the same specifications as the original chain that ships with EGO 16" models. It’s the recommended replacement to ensure correct alignment, tension, and safe operation. Using a chain with the wrong gauge or pitch can cause poor cutting and accelerated wear.

• Designed for EGO CS1600 and CS1604 16-inch bars
• .043 inch gauge to match the saw's guide bar groove
• 3/8 inch Low Pro pitch for correct sprocket engagement
• Direct OEM compatibility to prevent fitment issues

How does the low-kickback design improve safety?

The AC1600 uses cutter profiles and depth settings that reduce the chance of sudden upward reactions if the tip contacts material. Low-kickback chains minimize aggressive bite while maintaining effective cutting, which helps beginners and experienced users alike control the saw more predictably. This is a design choice, not a substitute for safe cutting technique and personal protective equipment.

• Reduced tip reaction risk compared to full-profile chains
• Smoother, more controlled cutting behavior
• Ideal for residential and general property maintenance tasks

What specification details should I check before buying?

Confirm your saw bar length and inspect the existing chain for gauge and pitch markings. The AC1600 is a .043 inch gauge, 3/8 in. Low Pro pitch chain intended for 16" bars. Replacing like-for-like keeps the chain running true in the bar groove and preserves sprocket life.

• Match bar length: 16 inches
• Match chain gauge: .043 in.
• Match pitch: 3/8 in. Low Pro
• Use genuine EGO parts for warranty-friendly replacement

How should I maintain this replacement chain for longer life?

Routine maintenance—proper tensioning, regular sharpening, and correct lubrication—keeps cutting performance steady and extends chain life. Inspect links for wear and replace the chain when cutters or drive links are damaged or excessively worn. Correctly tensioned chains also reduce strain on the motor and bar.

• Keep chain tensioned to manufacturer specs; retension after first few cuts
• Sharpen cutters periodically or have a pro service the chain
• Always run with adequate bar and chain oil to reduce friction
• Replace chain when drive links are worn or cutters are chipped

Who is this for: The EGO POWER+ AC1600 replacement chain is intended for EGO CS1600 and CS1604 owners who want a direct-fit, genuine replacement to maintain factory performance and safer cutting behavior. It’s suitable for homeowners and property caretakers doing routine pruning, limb work, and light felling who prefer an OEM-quality chain with a low-kickback profile.
