Now tension the Oilomatic chain by turning the tensioning screw (5) clockwise, making sure that the drive link tangs are lined up with the bottom groove of the bar. Hold the bar nose (8) up and turn tensioning screw (5) until the Oilomatic chain is properly seated on the underside of the bar. While still holding the bar nose up, tighten the collar nut (1) securely. The Oilomatic chain is correctly tensioned when it fits snugly on the underside of the bar but can still be pulled 22 easily around the bar. Engaging the chain brake When the hand guard is moved towards the nose of the guide bar the actuating lever automatically unlatches the brake lever and the spring-assisted brake band is clamped round the clutch drum at the same instant. This causes the sawchaintoibe brought to astandstill and locked in position. Releasing the chain brake " The locked saw chain must be released before cutting can be continued. To do this, pull the hand guard back against the handlebar - this disengages the brake band from the clutch drum.

The chain brake is subject to normal wear. !It is therefore necessary to have it regularly serviced and maintained by trained personnel, (STIHL servicing dealer) to insure that it is always in good working order.
