Lubri Jet® is an angled oil hole that virtually eliminates bar oil-hole plugging. The standard perpendicular oil hole position is changed to an angular position. The Lubri Jet® oil hole slopes up (towards the top of the bar) and forward (towards the nose). A Lubri Jet® oil hole is also approximately 40 per cent smaller in diameter than a standard hole. The smaller hole increases the velocity of the oil as it enters the bar, which helps clear sawdust and debris away from the hole during operation.

BENEFITS
  • The surface area on the chain's drive links exposed to incoming oil at the point where oil enters the bar groove is increased by 500 per cent.
  • Improved chain and bar lubrication results in a longer service life.
  • Drive links will pull sawdust and chips away from the oil-hole during operation.
  • The smaller size of the Lubri Jet® oil hole increases the velocity of incoming oil with no decrease in the volume of oil entering the bar groove.
  • Oil velocity at the point where oil enters the bar groove is increased by as much as 480 per cent.
  • Bar oil hole plugging during felling and bucking operations is reduced by 80 per cent. Sawdust and chips are blasted out.
  • Less down time on the job.


Lubri-Dam™ is exactly what its name implies, a dam that helps keep lubricant where it's needed. The Lubri-Dam™ feature resembles a small barrier located in the bottom of the guide bar’s groove, just behind the oil-hole.

BENEFITS
  • Oil in the bar groove is prevented from running out of the bar's tail, keeping more lubricant available to the bar and chain.
  • In tests, the thickness of oil film on the rails of bars with Lubri-Dam™ increased 135 per cent over the oil film thickness found on bars without Lubri-Dam™.
  • Bar oil hole plugging is reduced because the Lubri-Dam™ helps deflect sawdust and wood chips away from the oil hole.
  • An increase of available oil and a reduction of oil hole plugging combine to improve overall lubrication.
  • Cutting performance is enhanced and service life of the bar and chain is maximised.
