OPERATION

INITIAL PREPARATION

1. Place the log splitter on a firm, level surface.

2. Service engine with gasoiine and oil as

instructed in the separate engine manual packed

with your log splitter.

3. Lubricate the beam area where splitting wedge

will slide with engine oil (DO NOT USE

GREASE). Make certain to oil both front and back

of the beam face.

4. Fill the reservoir tank as follows.

a. Remove reservoir vent plug. See figure 12.

Using Dexron II automatic transmission fluid,

or low non-foaming hydraulic fluid, fill reser­

voir to the top. Replace vent plug securely.

NOTE:

Total capacity of system is approximately 7.6

gallons.

b. Disconnect the spark plug wire. Prime the

pump by pulling the recoil starter, to turn

the engine over, approximately 10 times.

Reconnect the spark plug wire.

c. Start engine. Use the control handle to extend

the wedge to the far extended position. Leave

the wedge in this position (do not retract).

Refill tank to within 1-1/2" to 2" from the top of

the tank.

Now retract the wedge. Extend and retract the

wedge fully 10 to 12 complete cycles to

remove trapped air in the system (system is

“self-bleeding”).

d.

e.

f. Refill the reservoir to within 1-1/2" to 2" from

the top of the tank. Much of the original fluid

has been drawn into the cylinder and hoses.

Make certain to refill the reservoir, to prevent

extreme damage to the hydraulic pump. Failure

to refill the tank will void your warranty.

NOTE:

Some fluid may overflow from the vent plug as

the system builds heat and the fluid expands and
seeks its own level.

A

WARNING: Do not operate the log splitter

without the proper amount of transmis­

sion fluid in the reservoir tank.

BEFORE STARTING

Before each use, check the following:

1. Place log splitter on a firm, level surface. For verti­

cal operation, pull the vertical position release rod

out and pivot it down to release the beam. Place

the beam in the vertical position. Lock the beam in

the vertical position, by pulling out on the locking

rod and pivoting it to the left. See figure 13.

2. Remove the vent plug and check the fluid level.

Fluid level should be 1-1/2" to 2" from the top of

the tank.

IMPORTANT: Reservoir tank must be full as instruct­

ed. Low fluid level will damage the pump and void

your warranty.

3. Lubricate the beam area where splitting wedge

will slide with engine oil (DO NOT USE

GREASE). Make certain to oil both front and back

of the beam face.

4. Fill gasoline tank as instructed in separate engine

manual.

5. Make sure fuel shut-off located under gasoline

tank is open.

6. Attach spark plug wire to spark plug.
