Oregon Tool R40 Chainsaw Chain 10 in 3/8 in Low Profile 40 Link

Product Description

The OREGON TOOL R40 is a 90PX-series chainsaw chain designed for small, low-powered saws used in light cutting work. It measures 10 inches in length with a 3/8-inch low-profile pitch and a .043-inch gauge, giving it a narrow kerf that reduces the power demand on the saw. The 40-link count fits a specific class of compact electric and gas chainsaws. The LubriTec oiling system keeps the chain and bar lubricated during operation, extending wear life between service intervals. Landscapers and homeowners running compact saws will find this chain delivers higher cutting efficiency without taxing a low-displacement engine.

This chain is suited for residential and light commercial landscaping applications where a compact chainsaw handles pruning, limbing, and small-diameter cutting tasks. The narrow kerf design is particularly effective on battery-powered and small-displacement gas saws where preserving motor efficiency matters. Compatible brands listed by the manufacturer include Echo, Ryobi, Craftsman, Husqvarna, Makita, and Milwaukee, among others. Always verify bar length, pitch, gauge, and drive link count against your specific saw model before ordering.

Key Features

• 90PX-series chain optimized for small, low-powered electric and gas chainsaws

Compatibility

The manufacturer lists compatibility with Echo, Ryobi, Craftsman, Husqvarna, Makita, and Milwaukee chainsaws accepting a 10-inch bar with 3/8-inch low-profile pitch, .043-inch gauge, and 40 drive links. Confirm all four specifications match your saw and bar before installation.

Installation Notes

Chain installation and tensioning should be performed by a qualified operator following the saw manufacturer's service manual. Always power down or remove the battery before handling the chain, and wear cut-resistant gloves throughout the process. Confirm bar groove width matches the .043-inch gauge before mounting. After installation, verify proper tension and lubrication flow before resuming cutting operations.
