Chainsaw Makita M 191H30-1 — 45 cm guide bar, 1.5 mm gauge, 0.325" pitch, 72 drive links

Chainsaw Makita M 191H30-1 — 45 cm guide bar, 1.5 mm gauge, 0.325" pitch, 72 drive links is a professional replacement chain and compatible guide combination designed for use on chainsaws that accept a 45 cm (approx. 18") guide bar, 1.5 mm gauge and 0.325" pitch. The product is intended for medium-duty cutting tasks and provides the specific dimensions required for correct fit and reliable cutting performance when matched to a compatible Makita chainsaw or equivalent models that share the same guide and chain specifications.

Advantages

This chainsaw chain and guide combination offers precise dimensional compatibility for easier installation and consistent cutting behavior. The 1.5 mm gauge and 0.325" pitch deliver a balance between cutting speed and control appropriate for a variety of wood types. The 72 drive links ensure correct engagement with the sprocket and guide, reducing the risk of skip or improper tensioning when used with a matching chainsaw. The construction and geometry are intended to support regular maintenance routines such as sharpening and tension adjustment.

Suitable for

• Forestry work involving medium-thickness trunks and branches
• Pruning and landscape maintenance requiring a 45 cm guide bar
• Cutting firewood and processing felled trees
• Replacement of worn chains on chainsaws with compatible bar, gauge and pitch

Key specifications

How to use

Before installation, confirm that your chainsaw supports a 45 cm guide bar, 1.5 mm gauge and 0.325" pitch with 72 drive links. Follow the chainsaw manufacturer's instructions for chain replacement: remove the sprocket cover, loosen the tensioner, position the chain around the guide bar and sprocket so the drive links seat correctly, adjust initial tension, and reattach the sprocket cover. After installation, set proper chain tension according to the chainsaw manual and perform a test cut on scrap wood to verify cutting behavior and final tension. Regularly lubricate the bar and chain and check for wear, damage or dullness before each use.

Usage recommendations

Use appropriate personal protective equipment including gloves, eye and hearing protection, and chainsaw chaps. Maintain correct chain tension and sharpness for safe, efficient cutting. For best results, sharpen the cutters with the correct file size for 0.325" pitch chains and follow a consistent maintenance schedule. Replace the chain if links are damaged, excessively worn, or if performance deteriorates despite proper sharpening and tensioning.
