Hipa 20" Chainsaw Chain 3/8" Pitch .050" Gauge 70L — 2-Pack Full-Chisel for Echo CS-590 & Poulan

The Hipa CS-590 20-inch replacement chainsaw chain is a 70-drive-link, full-chisel 3/8" pitch bar chain (.050" gauge) designed to fit Echo CS-590 and many Poulan, McCulloch and equivalent models.

This premium two-pack offers an affordable way to restore cutting performance on 20" guide bars used for yard work, storm cleanup and light commercial tasks. The CS-590 chain is manufactured to match common OEM specifications—3/8" pitch, .050" gauge and 70 drive links—with hardened, blued cutters that resist corrosion and maintain edge life when sharpened and maintained properly. Before ordering, confirm your saw’s pitch, gauge and number of drive links to ensure compatibility.

Will this chain fit my Echo, Poulan or McCulloch saw?

Compatibility hinges on three measurements: pitch, gauge and drive link count. The Hipa CS-590 is built to replace many 20" OEM chains specified as 3/8" pitch, .050" gauge and 70 drive links, including common Oregon and manufacturer part numbers.

• Pitch: 3/8"
• Gauge: .050" (1.27 mm)
• Drive links: 70
• Matches numerous OEM numbers such as Oregon E70, 72LPX070G and equivalents

How does the full-chisel cutter style affect cutting performance?

Full-chisel cutters produce faster, more aggressive cuts than semi-chisel designs, making them well-suited for felling and crosscutting soft and seasoned wood. They excel at rapid production but require more frequent sharpening and careful use around dirt or abrasive materials to preserve the teeth.

• Fast, efficient cutting on clean wood
• Sharpen more often than semi-chisel chains
• Best avoided for dirty, frozen or abrasive conditions

What maintenance and safety steps should I follow?

Regular maintenance keeps the chain cutting efficiently and extends service life. Check tension, lubricate the bar and chain, and inspect for damage before each use. Replace or sharpen the cutters when they become dull, and always wear required PPE while operating the saw.

• Set proper tension — not too tight or loose
• Keep the bar groove and oil ports clean
• Sharpen or replace dull cutters; balance left and right teeth
• Use eye, ear and hand protection during operation

How many chains are included and what makes this pack a smart buy?

This listing supplies two complete 20" chains, which reduces downtime during busy seasons and gives a ready spare for extended projects. Buying a two-pack can save you from halting work to order a replacement and often costs less per chain than single purchases.

• Includes two 20" chains (70 drive links each)
• Spares ready for quick swap-outs on site
• Cost-effective compared with buying chains individually
