Transporting

Transporting

The Model G0639 log splitter is not designed to be towed on logging roads, forest ser- vice roads, public roads, or highways. This machine is designed for job site towing only where maximum speed will not exceed 12 MPH. The log splitter must be transported between job sites on a trailer capable of car- rying 1000 lbs.

To tow the splitter:

1. Lower the log splitter cylinder and beam to the horizontal position and lock it in place.

2. Raise and lock the front and rear landing legs in the uppermost position with the lock pins.

3. Unlatch the receiver lock lever and place the receiver onto the tow ball.

4. Make sure that the tow ball is fully seated inside of the receiver.

5.Push down on the receiver lock lever until it pulls the lock tongue up against the under- side of the tow ball and locks the tow ball and receiver together.

6. Secure the safety chains to the tow vehicle and double check all your connections.

7. Close the fuel shutoff valve on the engine carburetor.

8. Make sure that the engine gas cap is secure and that there are no tools or lumber still on the log splitter. Never allow any riders or cargo on this log splitter while towing.

9. Tow this log splitter responsibly! Do not tow it while the engine is operating, and take pre- cautions to make sure the machine will not tip over during towing, causing a fuel leak and possible fire.

Control Valve

When the engine is running and the control valve lever is in the neutral position (Figure 20), the hydraulic pump delivers hydraulic fluid at 8 GPM through the control valve and back into the hy- draulic tank.

When you push the control lever to the forward position, the control valve diverts hydraulic fluid up to 3000 PSI to one side of the 4" splitter piston moving the splitter wedge into the log and split- ting the log in half. The maximum distance of the wedge stroke is 24".

When you push the control lever to the full back- ward position, the lever locks in retract mode, and the control valve diverts the hydraulic fluid to the other side of the splitter piston. As a result, both of your hands are free to load the next log for split- ting. When the ram fully retracts, the control lever automatically moves back to neutral, and the log splitter is ready to split another log.
