Chain Sharpener YATO YT-84980 — 18 V, 6,500 rpm, 108 mm disc, 2 Ah battery, metal guide

The YATO YT-84980 is a cordless chain sharpener designed for rapid restoration of saw chains. It is powered by an 18 V lithium-ion battery and runs at 6,500 rpm with a 108 mm grinding disc. Supplied with a 2 Ah battery, quick charger and a metal guide, the tool provides stable positioning and consistent grinding performance suitable for workshop or field use. Construction features such as a metal guide and compact, lightweight body support accurate, repeatable sharpening of common chainsaw chain types.

Advantages

The 18 V battery motor delivers full mobility without the need for a mains connection, while the 6,500 rpm no-load speed enables efficient material removal and faster sharpening cycles. The metal guide keeps the chain stable for uniform grinding and the ±35° angle adjustment allows matching the sharpening angle to different cutter profiles. A 108 mm disc covers most common chainsaw chain sizes and the included 2 Ah battery with charge-level indicator enables planned use and quick recharges.

Suitable for

• Maintenance of petrol chainsaws and electric chainsaws with standard chain profiles
• On-site sharpening in forests, construction sites or remote locations

How to use

Charge the supplied 2 Ah battery fully before first use and inspect the grinding disc for damage. Secure the chainsaw chain in the metal guide according to the tool's positioning marks, set the sharpening angle to match the chain's cutter profile (within the ±35° range) and switch the sharpener on. Apply light, steady contact between the grinding disc and each cutter, progressing along the chain to achieve consistent tooth geometry. Monitor the battery charge-level indicator during operation and allow the disc to cool between extended passes if necessary. After finishing, switch off the tool, remove the battery if storing for long periods and clean metal filings from the guide and housing.

Usage recommendations

Keep the supplied 108 mm grinding disc in good condition and replace it when worn or damaged; use only discs with compatible internal diameter and maximum thickness up to 3.2 mm. Match the sharpening angle to the chain manufacturer’s recommendations and perform light, successive passes rather than aggressive material removal to preserve tooth geometry and extend chain life.
