Maintenance

The engine must be off when performing any maintenance. If the unit was recently used, make sure that the engine has cooled to avoid burns.

1.After every use, wipe down the Log Splitter to remove any tree sap or dirt. This will extend the life of the unit. Always keep the wedge and base clean.

2.When storing, make sure the Log Splitter is locked in a location where children cannot reach it.

3.Read the maintenance section of the engine manual and follow all of the procedures.

Note: The recommended interval for changing the hydraulic oil and filter is approximately every 3 months.

4.BEFORE TRANSPORTING, inspect the general condition of the Trailer. Check for loose Bolts and Nuts, misalignment or binding of moving parts, cracked, bent, or broken parts, exces- sively worn Safety Chain , damaged Tail Lights/Side Running Lights/Wiring Harness, loose Lug Nuts, loose Hitch connection, and any other condition that may affect its safe operation. If abnormal noise or vibration occurs, have the problem corrected before further use. Do not use damaged equipment.

5.BEFORE TRANSPORTING, check the Tires for wear and proper inflation (60 PSI).

6.BEFORE TRANSPORTING AND AT 500 MILE INTERVALS DURING EVERY TRIP, check and tighten the Tire Lug Nuts. Torque from 85 to 90 Ft.-Lbs.

7.EVERY 2,000TO 3,000 MILES OFTRAVEL, lubricate the Hub Assemblies with a heavy weight bearing grease. Follow the Bearing Packing Instructions as explained on the last page of this manual. After each Hub Assembly is reassembled, tighten the Castle Nut until the wheel starts spinning with slight resistance. Loosen the Castle Nut about 1/2 turn from this point. Insert a new Cotter Pin through the Castle Nut and the hole in the axle. Bend the Pin back, locking it and the Nut in place.

Bleeding the Hydraulic System

If the Log Splitter begins to lose power or splitting efficiency, it may be a result of air becoming trapped in the hydraulic system. Follow the steps below to bleed air from the system.

1.Loosen the Oil Plug (37) and make sure the o-ring is out of the way to expose the air hole in the Oil Plug (37).

2.Remove the spark plug from the engine (see engine manual) to keep the engine from starting during this process.

3.Push the Directional Valve (58) forward, toward the front of the Cylinder (1) (see FIGURE 1).

4.Pull the engine starter cord 10-15 times until the hydraulic cylinder piston moves forward. CAUTION: Keep everything away from the splitting edge during this process.

5.Tighten the Oil Plug (37).

6.Replace the spark plug.

7.Test the Log Splitter to make sure it is operating properly. If not, repeat the above process.

Warning! Only a qualified technician should repair or service the inter- nal hydraulic system of this unit.
