Step 1: Stake on the Left (1) and Right girder (2) and align the walls with the Splitter assembly (3) according to drawing LS8-1.0. Use welding fixtures to prevent deformation of the elements during welding. Tack weld in a few spots.

Step 2: Position the Foot frame (4) as shown in drawing LS8-1.0 on the manual log splitter plans. Tack weld them in place.

Step 3: Check alignment of the elements. You can try to slide the Damping plate in the slot formed by the L-profiles. It has to slide without retaining. If there is no gaps complete the welds of both elements.

Step 4: Position the Wheel (5) concentric to the bushings, already welded to the L-profiles, (see drawings LS8-1.1 and LS8-1.2) and thread the Clevis pin (6). Mount the Washer (7) and lock with Cotter pin (8).

Step 5: Take the Pusher assembly (9) and slide the Damping plate in the slot. Position the assembly about 20 inches from the Splitter. Mount the Bottom plate (10) using the Washers (11) and Screws (12). 

Step 6: Proceed to mounting the Hydraulic Jack (13). Use the Clevis pin (14), Washer (15) and Cotter pin (16).

Step 7: Mount the Handle (17) and Spring (18). Make sure the Jack is aligned with the Collar on the Pusher.
