Electrical Safety

  1. Ground fault circuit interrupter (GFCI) protection should be provided on the circuit(s) or outlet(s) to be used for the log splitter. Receptacles are available having built-in GFCI protection and may be used for this measure of safety.
  2. To reduce the risk of electric shock, this appliance has a 3-prong grounding plug. Use this appliance only with a 3-prong, UL-listed (CSA certified in Canada) extension cord recommended for outdoor use. Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the tool’s plug.
  3. To prevent electric shock, use only with an extension cord suitable for outdoor use, such as SW, SOW, STW, STOW, SJTW, or SJTOW. Before use, check that the extension cord is in good condition. When using an extension cord, make sure to use one heavy enough to carry the current your product will draw. For lengths less than 50 feet, a No. 12 AWG extension cord should be used. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating.
  4. To prevent the appliance cord from disconnecting from the extension cord during operation, make a knot with the two cords as shown in Table 1.Table 1. Method of Securing Extension Cord
  5. Do not abuse the cord. Never pull the log splitter by the cord or yank the cord to disconnect it from the receptacle. Keep the cord away from heat, oil, and sharp edges.

GROUNDING INSTRUCTIONS

  1. In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This tool is equipped with an electric cord having an equipment-grounding conductor and a grounding plug.
  2. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.
  3. Do not modify the plug provided – if it will not fit the outlet, have the proper outlet installed by a qualified electrician.
  4. Improper connection of the equipment-grounding conductor can result in a risk of electric shock. The conductor with insulation having an outer surface that is green with or without yellow stripes is the equipment grounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal.
  5. Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded.
  6. Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the tool’s plug.
  7. Repair or replace damaged or worn cord immediately.
  8. This tool is intended for use on a circuit that has an outlet that looks like the one illustrated in Sketch A in Figure 2. The tool has a grounding plug that looks like the plug illustrated in Sketch A in Figure 2. A temporary adapter, which looks like the adapter illustrated in Sketches B and C, may be used to connect this plug to a 2-pole receptacle as shown in Sketch B if a properly grounded outlet is not available. The temporary adapter should be used only until a properly grounded outlet can be installed by a qualified electrician. The green-colored rigid ear, lug, and the like, extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box.

PERMANENTLY CONNECTED TOOLS

  1. This tool should be connected to a grounded metal permanent wiring system; or to a system having an equipment-grounding conductor.
  2. USE PROPER EXTENSION CORD. Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Table 2 shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

EXTENSION CORDS

  1. Use only three-wire outdoor extension cords that have three-prong grounding plugs and grounding receptacles that accept the appliance’s plug.

Operation

WARNING! Before using the log splitter, review the instructions below and all safety information. Failure to follow these instructions may result in property damage or injury to the operator or bystanders.

WARNING! Before the initial operation, the bleed screw should be adjusted to allow air to go in and out of the oil tank. (loosen three to four turns). Airflow should be detectable during operation. To avoid leaking oil close the bleed screw when moving the machine.

Important! Failure to open the bleed screw during operation will result in permanent damage to the log splitter.

WARNING! Do not adjust the max. pressure limiting screw. This was set at the factory so the log splitter works under the maximum pressure limit of 5 tons. Tampering with the screw will result in hydraulic pump failure. Only a professional mechanic shall adjust the max. pressure limiting screw.

Splitting Operation

Follow these instructions to operate the log splitter:

  1. Ensure all logs meet the proper size requirements [(max log diameter: 10 in. (25.4 cm); max log length: 20.5 in. (52 cm)].IMPORTANT! Logs vary in hardness and structure. Small logs with knots or harder wood may be more difficult to split. Larger logs with less hardness may not be difficult to split. Do not force the log splitter if the log fails to split on the first attempt.
  2. When loading or positioning a log, always handle the bark side; never handle the ends. Never place your hands or body parts between the log and the splitter.
  3. Make sure all moving parts is completely stop. Never load or unload logs while the log pusher is moving.
  4. Check that bleed Screw is open.
  5. Load the log lengthwise into the unit between the wedge and the log pusher. Be sure that the split will be along the grain. Check to make sure the log is fixed stably.WARNING! Always set logs firmly on the log retaining plates and the log rail. Make sure logs will not twist, rock or slip while being split. Do not force the blade by splitting the log on the upper part. This will break the blade or damage the machine (Fig. 3).WARNING! Never load or unload logs while the log pusher is moving.
  6. Plug the appliance cord into an appropriate power outlet.
  7. Engage the log pusher by using your left hand to push the hydraulic control lever and your right hand to push the On/Off switch (Fig. 4).NOTE: This log splitter is equipped with ZHB control system, which requires both the On/Off switch and the hydraulic control lever to be engaged simultaneously to start the machine.
  8. The log pusher will move forward and the log will be split by the splitting wedge.

Duty Cycle

  1. The electric log splitter is designed for occasional use. Use over a long period will overheat the motor and may cause damage.
  2. The electric log splitter should not operate at 15A load for more than 5 minutes at a time, after which it must be switched off and allowed to cool down for at least 10 minutes before restarting.

WARNING! If the log cannot be split within 5 seconds, do not engage the log pusher any more, otherwise the log splitter will be damaged. For extremely hard logs, rotate it by 90° to see if it can be split in a different direction. If the log still cannot be split, its hardness exceeds the capacity of the machine and thus that log should be discarded to protect the log splitter.

WARNING! Break log in the direction of its growing grain. Do not place log across the log splitter for splitting. It may be dangerous and may seriously damage the machine.

WARNING! Do not attempt to split 2 log pieces at the same time. A piece may fly up and cause personal injury.

WARNING! Accidents occur when there is more than one person involved in loading and operating the log splitter; only one person should operate the splitter. If a second person is assisting in loading the splitter, NEVER allow an assistant to hold the log in place while the operator is using the unit.

9. Release both the hydraulic control lever and the On/Off switch, the log pusher will move to the original position. Wait until the wood pusher completely stops, and remove the split log.

Removing A Jammed Log

If the log gets stuck on the wedge base, or the wedge becomes embedded in the log and will not completely split or separate from the log, follow the directions below to remove the log.

WARNING! Do not attempt to remove the jammed log with your hands or knock it off. It may cause serious injury or damage to the machine.

  1. Release both the hydraulic control lever and the On/Off switch.
  2. After the log pusher moves back and completely stops at its starting position, insert a wedge wood under the jammed log (Fig. 5).
  3. Start the log splitter to push the wedge wood to go completely under the jammed one.
  4. Repeat above instructions 2 – 3 with a sharper sloped wooden wedge as needed until the log is free.

WARNING! Do not try to knock the jammed log off. It will damage the machine or may launch the log and cause an accident or injury (Fig. 6).

Maintenance

WARNING! Always disconnect the power and ensure built up pressure has been released from the tool before cleaning, repairing, or inspecting the log splitter.
