Oregon Tool 27850 Advancecut 20 Inch Bar Chain Combo

Product Description

The OREGON TOOL 27850 is a bar and chain replacement combo designed for 20-inch guide bar applications on gas and electric chainsaws. The kit pairs a reversible guide bar with a low-kickback saw chain, reducing operator risk during cutting tasks. The AdvanceCut chain is engineered for smooth, efficient cuts through hardwood and softwood. At 3.284 pounds, the combo is lightweight relative to its bar length, which helps reduce fatigue during extended use. With 70 drive links, the chain is matched precisely to the 20-inch bar included in the set. This combo is a direct replacement intended for professional arborists, tree service technicians, and experienced chainsaw operators.

The 27850 combo suits residential and light commercial cutting applications where a 20-inch bar is the standard setup. Typical use cases include felling medium to large trees, bucking logs, and limbing operations. The symmetrical bar design allows the bar to be flipped end-for-end during routine service intervals, distributing wear evenly and extending bar service life. The low-kickback chain configuration meets safety requirements commonly specified in professional chainsaw maintenance programs.

Compatibility

Designed as an OEM-style replacement bar and chain combo for chainsaws accepting a 20-inch guide bar with a 70 drive link chain configuration. Verify bar mount, pitch, and gauge specifications against your saw's requirements before installation.

Installation Notes

Bar and chain replacement should be performed by a qualified operator familiar with chainsaw service procedures. Disengage the chain brake, remove the bar cover, and ensure the saw is fully powered off and the spark plug boot is disconnected before beginning work. Proper chain tension must be set after installation according to the saw manufacturer's service guidelines — a correctly tensioned chain lifts slightly off the bar rail but cannot be pulled free by hand. Always wear cut-resistant gloves and eye protection during chain handling and tensioning.
