STARTING INSTRUCTIONS: 

1. 

Turn engine switch to “ON” position. (See Illustration A) 

2. 

Turn fuel valve to “ON” position. (See Illustration B) 

3. 

Move the throttle lever to “FAST”. Always operate the engine with throttle lever in the “FAST” position. 

4. 

Move choke control lever to “CHOKE” position. 

5. 

Grasp rope handle and pull slowly until resistance is felt. Then pull rapidly to start engine and avoid 

engine kickback. 

6. 

Allow the engine to warm up. If operating in warm weather, move the choke control lever toward “RUN” in 

small increments over several seconds. For cold weather operation do this procedure over several 

minutes. Operate with choke lever in the “RUN” position. 

7. 

To stop engine, move the throttle lever to the “SLOW” position. 

NOTE: The maximum governed speed on the engine is preset at the factory to 3,600 RPM no load 

speed. When splitting wood, the throttle should be set at the maximum setting to develop the 

horsepower required for the pump.

 

8. 

Turn switch to “OFF” position.   

NOTE: The switch is located on the side of the engine. 

 

WARNING 

ALWAYS WEAR SAFETY GLASSES DURING OPERATION AND KEEP HANDS AND FEET 

CLEAR OF RAM, STRIPPER CHANNELS AND FOOT PLATE AT ALL TIMES. 

DO NOT OPERATE LOG SPLITTER IF THE OIL LEVEL IS MORE THAN TWO INCHES 

FROM TOP OF TANK WHEN THE WEDGE IS IN THE RETURNED POSITON. 

 

9. 

For your convenience the ram/beam assembly can be elevated, providing more comfort in certain 

situations. To raise the beam/ram assembly, pull lock pin first then replace when up. Place one foot on the 

axle and pull with an upward and back motion. Once the ram/beam is elevated be sure to lock the beam 

into position with locking pin.
