Use extreme care when handling gasoline. Gasoline is extremely flammable and the vapors are explosive. Never fuel the machine
indoors or while the engine is hot or running.
Excessive pressure when seating beads may cause tire/rim assembly to burst with force sufficient to cause serious injury.
Adjusting the Throttle Linkage
After you have the Log Splitter fully assembled, the Throttle Linkage of the
Subaru (9HP) Engine will need further adjustment. This procedure must be
done before operating your Log Splitter. The following information explains the
adjustment procedure.
Tools needed:

Ratchet with Extension

10mm Socket
1. Move the Throttle Lever to check if it will stay in the RUN position or if it
returns to the IDLE position (Figure 13).
2. If the Throttle Lever stays in the RUN position then adjustment is not
needed.
3. If the Throttle Lever returns to the IDLE position, go to the next step.
4. Use the Ratchet and Extension with the 10mm Socket to tighten the Throttle
Linkage Nut until the Throttle Lever will stay in the RUN position (Figure 14).
Note: The Throttle Lever Nut should be tight enough to hold the Lever in the RUN
position while operation of the Log Splitter but not so tight that it is difficult
to move the Lever back to IDLE position by hand.
SET UP
Gas and Oil Fill-Up
Service the engine with gasoline and oil as instructed in the engine manual
packed with your log splitter. Read the instructions carefully.
Note: Your log splitter is NOT shipped with motor oil in the engine. You MUST add oil before operating the splitter for the first time and
check the oil level before each use. Be careful not to overfill. Gasoline can be added to the engine when the log splitter is in either
the horizontal or vertical position. However, it may be easier when the splitter is in the vertical position.
Tire Pressure
The max recommended operating pressure is shown on the side of the Tire. Never exceed the manufacturer’s recommended psi.
Maintain equal pressure on all tires.

You must add oil before starting the engine. This machine is shipped without oil. Traces of oil may be in the reservoir from
factory testing, but you must add oil before starting the engine. Fill the reservoir slowly, checking the level frequently to
avoid overfilling.
