Air flow through the bleed screw hole should be detectable when the log splitter is in use. before moving the log splitter, make sure the bleed screw is tightened to avoid oil leakage. YS0552PM02 - 1703 Log Splitter Stand Hydraulic Control Lever bleed Screw Return Stop Oil Drain bolt w/ Dipstick Max Pressure Limiting Screw Failure to loosen the bleed screw will keep the sealed air in the hydraulic system compressed. Continuous air compression and decompression will blow out the seals of the hydraulic system and cause permanent damage to the log splitter. Know Your Machine | 8 MAX PRESSURE LIMITING SCREW Max pressure was preset at the factory by a qualified mechanic using professional tools. Unauthorized resetting will prevent the hydraulic pump from providing enough splitting pressure or RESULT In SERIOUS InJURY AS WELL AS DAMAGE TO THE MACHInE. Do not adjust the max pressure limiting screw! OPERATION OPERATING CONDITIONS Your YARDMAX log splitter is designed to operate in temperatures between 40°F and 100°F and at altitudes of 3,200 feet above sea level. The surrounding humidity should be less than 50% at 100°F. It can be stored or transported in temperatures between -10°F and 130°F. ELECTRICAL REQUIREMENTS Confirm that you have a US Standard, 3 pin grounded, Type B 15 AMP (nEMA 5-15). Check that the electric circuit is grounded, adequately protected, and that it corresponds with the power, voltage, and frequency of the motor. STAKE ON LEVEL GROUND To secure your YARDMAX log splitter, use two bolts or stakes on level ground. Due to varying ground surfaces, these are not included. Choose the right type of bolt or stake for your surface type or call us for a recommendation. If the log does not begin to split after 5 seconds of operation, release both controls. The motor or hydraulic fluid may overheat and damage your log splitter. TWO HANDS OPERATION For your safety, your log splitter is equipped with a "ZHb" control system that requires both hands of the operator. The left hand controls the hydraulic control lever while the right hand controls the pushbutton switch. The log splitter will stop if the lever or pushbutton are released. Only after the lever and pushbutton are released will the log ram return to its starting position. 9 | Know Your Machine & Operation SPLIT HARD WOOD For extremely hard wood, rotate your log 90° to see whether it can be split in a different direction. If the log cannot be split, then its hardness exceeds the machine's capacity. LOAD A LOG When loading a log, place hands on the sides of the log, not the ends. Make sure logs will not twist, rock, or slip while being split. YS0552PM02 - 1703 Electric Log Splitter » Operator's Manual Do not put any logs on the log splitter at this stage. Keep the control lever pressed down the prevent the ram from returning. 2. Loosen the handwheel on the return stop. Move the stop towards the splitter to shorten the stroke. 3. Slide the stop to the desired position. 4. Tighten the handwheel on the return stop to lock it into positon. 5. Make sure your hands are clear of the ram, and release the control lever. The ram should return as far as the stop will allow. 1 2 Do not split logs on the upper part of the blade. This could break the blade or damage the machine. ADJUSTING THE RETURN STOP 3 4 If you are splitting a pile of shorter logs, you may want to prevent the pusher plate returning all the way back to start, this will speed up future operations. To adjust how far the pusher plate comes back: 1. Extend the ram fully. When the ram is at full extension, release the push button switch. YS0552PM02 - 1703 Operation | 10 FREEInG A JAMMED LOG Release both controls. After the log ram moves back to its starting position and completely stops, insert a wood wedge under the jammed log. Start the log splitter to push the wood wedge completely under the jammed log. Never try to knock a jammed log off the splitter with your hand or another object. This could damage the tool or cause the log to fly up and hit someone. Repeat above procedure with sharper-sloped wood wedge until the log is completely freed. 11 | Freeing a Jammed Log YS0552PM02 - 1703 Electric Log Splitter » Operator's Manual REPLACInG HYDRAULIC OIL Disassemble the log tray table before replacing the hydraulic oil. Replace the hydraulic oil in your YARDMAX log splitter after every 150 hours of use. Follow these steps to replace it: Make sure all moving parts stop and the log splitter is unplugged. Unscrew the oil drain bolt with dipstick to remove it. Tip the log splitter so the oil drain plug is higher than the motor and refill with 3.7 quarts of fresh hydraulic oil. Tip the log splitter so the motor end is higher than the oil drain plug, and drain oil over a 1- gallon container. Clean the surface of the dipstick and put it back in the oil tank while keeping the log splitter vertical. Make sure the level of the refilled oil is between the two grooves on the dipstick. MAX MIN YS0552PM02 - 1703 Replacing Hydraulic Oil | 12 Clean the oil drain bolt with dipstick before screwing it back in. Tighten it to avoid leakage before setting the log splitter down. Periodically check oil level to ensure it is between the two grooves on the dipstick. Refill with oil if it becomes low. The following hydraulic oils or equivalents are recommended for your log splitter's hydraulic transmission system: 10W AW32 ASLE H-150 ISO 32 SHARPEnInG THE WEDGE Over time your YARDMAX log splitter wedge will dull. If you notice decreased performance, we recommend sharpening the wedge using a fine-toothed file, smoothing any burrs or crushed areas along the cutting edge. For questions about sharpening the wedge, call us at 844-YARDMAX. 13 | Replacing Hydraulic Oil & Sharpening the Wedge YS0552PM02 - 1703 Electric Log Splitter » Operator's Manual TROUbLESHOOTInG Problem Cause Fails to split logs 1.
