4.Lift and slide the cylinder up to the top of beam and into the weld brackets.

5.Attach the dislodger over the wedge assembly and secure it to the weld brackets with the previously removed hardware.

NOTE: Once the six hex screws are tightened, there may be a slight gap between the dislodger and the weld brackets. This gap is normal.

6.Reattach the log cradle to the side of the beam with the control valve, aligning the ends of the cradle with the beam flanges.

7.Roll the log splitter off the bottom crate.

Preparing the Log Splitter

1.Lubricate the beam area (where the splitting wedge will slide) with engine oil. Do not use grease.

2.Remove the vented reservoir dipstick, which is located in front of the engine on top of the reservoir tank. See Figure 3-6.

IMPORTANT: The log splitter may have been shipped and primed with hydraulic fluid in the reservoir tank. However, you MUST check the fluid level before operating.If the reservoir tank is not filled, proceed with the following steps:

3.Fill the reservoir tank with the hydraulic fluid included with this machine (if equipped) or one of the approved fluids which include

Dexron® III / Mercon® automatic transmission fluid or a 10 Weight

AW hydraulic oil.

4.Check the fluid level using the dipstick. See Figure 3-6.Do not overfill.

5.Replace the vented dipstick securely, tightening it until the top of the threads are flush with top of the pipe.

6.Disconnect the spark plug and prime the pump by pulling the recoil starter as far as it will go. Repeat approximately 10 times.

7.Reconnect the spark plug wire and start the engine following the instructions in the OPERATION section.

8.Use the control handle to engage the wedge to the farthest extended position. Then retract the wedge.

9.Refill the tank as specified on the dipstick.
