Rachman Sentosa

A true professional saw built for very demanding applications, including felling and general logging. The 385 XP® is engineered for higher horsepower in tougher conditions, like larger diameter timber. The crankcase and crankshaft are extra heavy-duty and the carburetor has vibration damping in order to handle high speeds and high loads. This saw combines low weight, high power and rapid acceleration with flexible operation.

Features

Air Injection
Centrifugal air cleaning system removes larger dust and debris particles before reaching the air filter. This results in reduced air filter cleanings and improved engine life.
Inertia activated chain brake
Reduces the likelihood of injury due to kickback.
LowVib®
System designed to reduce vibration levels to the operator, which lessens fatigue.
Magnesium crankcase
Sturdily built crankcase withstands high rpms and tough professional use, ensuring a long service life.
Three-piece crankshaft
Forged three-piece crankshaft for maximum durability for the toughest applications.
