ELECTRICALCONNECTION CONNECTION ELECTRICAL ELECTRICAL SAFETY EXTENSION CORDS Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the tool's plug. When using a power tool at a considerable distance from the power source, use an extension cord heavy enough to carry the current that the tool will draw. An undersized extension cord will cause a drop in line voltage, resulting in a loss of power and causing the motor to overheat.

IMPORTANT SAFETY INFORMATION GENERAL SAFETY Failure to follow these instructions may result in serious injury or death. ALWAYS read the operator’s manual before operation. NEVER allow children to operate this log splitter. NEVER allow adults lacking proper instructions and understanding to operate this log splitter. KEEP all people and pets a minimum of 25 feet away from your work area when operating this log splitter. Only the operator is to be near the log splitter during use. ALWAYS wear safety glasses.
WORK AREA NEVER operate the log splitter on slippery, wet, muddy or icy ground. ONLY operate your log splitter on level ground. Operating on a slope could cause the log splitter to roll over or logs to fall off. NEVER attempt to move your log splitter over hilly or uneven terrain. ALWAYS block the wheels to prevent movement of the log splitter while in operation. NEVER leave tools or pieces of wood on the tool while it is in operation.
KNOW how to stop the log splitter and disengage the controls before operating it. NEVER place hands or feet between the log and splitting wedge during forward or reverse stroke. Serious injury or death could result. NEVER straddle or step over the log splitter during operation. NEVER reach or bend over the log splitter to pick up a log. NEVER try to split two logs on top of each other. NEVER try to cross split a log. NEVER attempt to load your log splitter when the ram or wedge is in motion.
HYDRAULIC SAFETY The hydraulic system of your log splitter requires careful inspection along with the mechanical parts. Be sure to replace frayed, kinked, cracked or otherwise damaged hydraulic hoses or hydraulic components. NEVER check for leaks of hydraulic fluid with your hand. Fluid escaping from a small hole can be almost invisible. Escaping fluid under pressure can have sufficient force to penetrate skin causing serious personal injury or even death.
UNPACKING & ASSEMBLY \UNPACKING This product has been shipped pre-assembled (see FIGURE 3). • Carefully remove the log splitter and all accessories from the box. Make sure that all items listed in the packing list are included. • Inspect the tool carefully to make sure no breakage or damage occurred during shipping. • Do not discard packing materials until you have carefully inspected and satisfactorily operated the tool. • If any parts are damaged or missing, please call 1-800-780-2677 for assistance.
PRE-OPERATION INSTRUCTIONS WARNING: Do not allow familiarity with tools to make you careless. Remember that a careless fraction of a second is sufficient to inflict serious injury. Log preparation: Logs should be cut with square ends. Never split logs larger than 10 in. diameter or 20-1/2 in. long. Uneven logs (e.g. knotted, curved, etc.) should not be used. Oil the wedge and upper side of the machine body. This will allow the log to move smoothly on the surface (see highlighted parts on FIGURE 4.).
OPERATING INSTRUCTIONS 1. 2. 3. 4. 5. Plug the unit into a 3 prong outlet. Press the power button to turn the log splitter on. Place the log firmly against one of the wedges. Move control handle down to split the log. Release the handle to retract the ram automatically and begin loading the next log. When the machine is no longer in use, switch it off and unplug the power cable. (FIGURE 5). NOTE: a) Ensure that the horizontal distance between the splitter and outlet is more than 5 feet.
SPLITTING LOGS See FIGURE 5. Always place logs lengthwise on the work table and resting firmly on the side supports with one end against the wedge. Place logs flat and in the direction of the grain. Never angle the log to split it or place the log crosswise on the splitter. Never split more than one log at a time. • • • WARNING: Never keep pressure on the wood by trying to force the log splitter for more than three seconds. After five seconds, the oil will heat up and could damage the tool.
MAINTENANCE WARNING: When servicing, use only identical replacement parts. Use of any other parts may create a hazard or cause product damage. REPLACING HYDRAULIC OIL See FIGURES 6, 7, 8, 9. The hydraulic oil in the log splitter should be changed every 100 hours of use. • • WARNING: Only the parts shown on the parts list are intended to be repaired or replaced by the customer. All other parts should be replaced at an Authorized Service Center.

TROUBLESHOOTING Problem Possible Cause Solution Motor fails to start. • Overload Protection Device is disengaged to protect the log splitter from being damaged. • Switch off the motor and unplug the power cable. Let motor cool down for half an hour and restart. If this does not solve the problem, call your dealer for customer support. The log splitter won’t split logs. • • Log is improperly positioned. The size or hardness of the log exceeds the machine’s capacity. Wedge cutting edge is blunt.
