4 Top off coolant and leave filler opening at coolant expansion tank open. 5 Remove oil filler cap. 6 Remove air filter (09-400 or 09-410). 7 Connect cylinder leaktightness tester to a compressed air system and calibrate tester. 8 Position piston of No. 1 cylinder to ignition TDC. This is done by turning the crankshaft with a tool combination consisting of wrench socket (27 mm, l/2” square) and reversible ratchet handle, at the central bolt (front of crankshaft). Note The respective pistons are in the TDC position when the markings shown in the drawing opposite on the vibration damper or on the belt pulley are below the TDC pointer. 9 Open throttle fully.
