Lubricant for petrol saw and brushcutter gearboxes Unimet SM 7, 90 ml bottle

Unimet SM 7 is a 90 ml gearbox lubricant formulated for petrol chainsaws and brushcutters. Designed for lubrication of gears and bearings in small engine gearboxes, this product reduces friction and wear, supports smooth gear engagement and provides corrosion protection for metal surfaces. The compact bottle is intended for workshop maintenance and field servicing of outdoor power tools where precise application and portability are important.

Advantages

The lubricant provides reliable film strength that helps extend gearbox component life and maintain performance under variable load. Its formulation resists washout and disperses evenly across gear teeth and bearing surfaces to minimise pitting and scoring. The small, controlled-dispense bottle makes application simple and reduces waste during on-site maintenance.

Suitable for

• Petrol chainsaw gearboxes
• Brushcutter and trimmer gearboxes
• Small engine gear sets and bearings in handheld outdoor tools
• Field maintenance and portable repair kits

How to use

Before application, clean the gearbox area to remove dirt, sawdust and old lubricant residues. Apply a small amount of lubricant directly to gear teeth and bearing contact points using the bottle nozzle, ensuring even coverage. Operate the tool briefly at low speed to distribute the lubricant through the gearbox, then wipe away any excess. Follow the tool manufacturer’s maintenance intervals and service instructions when deciding reapplication frequency.

Usage recommendations

Store the product in a cool, dry place away from direct heat and open flames. Use appropriate personal protective equipment when servicing equipment and avoid contact with skin or eyes. Dispose of empty containers according to local regulations and avoid releasing used lubricant into the environment.
