MAINTENANCE SAFETY 1. Stop the engine, disconnect the spark plug and ground it against the engine before cleaning or inspecting the machine. NEVER perform any service or repair on your log splitter without first removing the spark plug wire. 2.

ASSEMBLY & SET-UP INSTRUCTIONS SET-UP Gas and Oil Fill-Up Service the engine with gasoline and engine oil as instructed in the engine manual provided with your log splitter. Read the instructions carefully. WARNING! Use extreme care when handling gasoline. Gasoline is extremely flammable and the vapors are explosive. Never fuel the machine indoors or while the engine is hot or running. NOTE: Your log splitter may be shipped without engine oil. You MUST check the oil level before operating.
Filling the hydraulic oil reservoir The log splitter is shipped without hydraulic fluid in the reservoir so you must fill the reservoir before your initial use. 1. Remove the vented reservoir dipstick, which is located on top of the reservoir tank. See FIGURE 17. ISO 68 Please select the oil based on the outside temperature range the log splitter will be used in. Refer to the chart provided to select the appropriate hydraulic oil.
OPERATION INSTRUCTIONS STARTING & STOPPING THE ENGINE 1. Place the log splitter on flat, dry, solid ground. 2. Block both wheels to prevent your log splitter from moving during operation. 3. Refer to the Engine Operator’s manual provided with your log splitter for instructions on starting and stopping the engine. USING CONTROL HANDLE The control handle has three positions. See FIGURE 14.
OPERATION INSTRUCTIONS SPLITTING THE WOOD 1. Start the engine as instructed in the Engine Operator’s manual included with the log splitter. 2. Grasp the log on the sides, place it on top of the beam against the front end plate to split the wood in the direction of the grain. See FIGURE 15. 3. To stabilize the log place your left hand on the side of the log. See FIGURE 15. WARNING! Never place a hand on the ends of the log, between the log and the end plate or the log and the splitting wedge.
OPERATION INSTRUCTIONS TRANSPORTING THE LOG SPLITTER 1. This log splitter has a built-in wheeled trailer jack for easy maneuvering. 2. Crank the jack up or down using the jack handle to position the hitch coupler over the tow ball behind your vehicle. See FIGURE 16 3. Pull the latch on the hitch coupler up and place the coupler onto the tow ball then close the latch to lock the ball securely.
MAINTENANCE & ADJUSTMENTS Regular maintenance is the best way to ensure good performance and a long life for your machine. Please refer to this manual and the engine manufacturer’s owner’s manual for maintenance procedures. WARNING! Do not make any adjustments without first stopping the engine, disconnecting the spark plug wire and grounding it against the engine. Always wear safety glasses during operation or while performing any adjustments or repairs.
(FIGURE17) (FIGURE18) 6. Refilling the reservoir tank (Please follow the steps on Page 20 to fill the reservoir tank). 7. Maintain the fluid level within the range specified on the dipstick at all times. See FIGURE 18. NOTE: When checking the fluid always make sure to push the dipstick in a twisting motion all the way down to make sure you are getting an accurate reading. NOTE: Always dispose of any used hydraulic fluid and engine oil at approved recycling centers only.
