Compression Test— Compression Gauge Check
1. Make sure the oil in the crankcase is of the correct viscosity and at the correct level and that the battery (10655) is correctly charged. Operate the vehicle until the engine is at normal operating
temperature. Turn the ignition switch to the OFF position, then remove all the spark plugs
(12405).
2. Set the throttle plates in the wide- open position.
3. Install a compression gauge such as the Compression Tester in the No. 1 cylinder.
4. Install an auxiliary starter switch in the starting circuit. With the ignition switch in the OFF position, and using the auxiliary starter switch, crank the engine a minimum of five compression
strokes and record the highest reading. Note the approximate number of compression strokes Klj . 7 ba
