CHAIN BRAKE® MECHANICAL TEST Your chain saw is equipped with a CHAIN BRAKE® that reduces possibility of injury due to kickback. The brake is activated if pressure is applied against brake lever when, as in the event of kickback, operator’s hand strikes the lever. 3-5A A WARNING The purpose of the CHAIN BRAKE® is to reduce the possibility of injury due to kickback; however, it cannot provide the intended measure of protection if the saw is operated carelessly. If 2-cycle lubricant other than Genuine Factory Parts Custom Lubricant is to be used, it must be a premium grade oil for 2-cycle air cooled engines mixed at a 40:1 ratio. Do not use any 2-cycle oil product with a recommended mixing ratio of 100:1. If insufficient lubrication is the cause of engine damage, it voids the manufacturer’s engine warranty for that occurrence. ENGINE PRE-START CHECKS FUEL MIXING TABLE WARNING Never start or operate the saw unless the bar and chain are properly installed. Be certain the CHAIN BRAKE® is disengaged (C) before starting unit (Figure 5-1A). Using a Phillips or slotted screwdriver - turn screw 1/4 to 1/2 turn clockwise (to the right). (Figure 5-2H) NOTE: If chain turns while idling - turn screw back to the left until chain stops and unit continues to idle.
