See FIGURE 8. 1. Stand the beam upright on a flat level.
STEP 5: Attach the hoses. See FIGURE 9. 1. Oil suction hose Ø24, is included in the hardware kit box, labeled as ① Loosen the hose clamps on both ends using a flat head screwdriver, and then connect one end of the hose to the fitting at the bottom of the pump, the other end to the bottom fitting on the reservoir. Tighten the hose clamps. 2. Pump / Valve connecting hose 1/2” labeled as ②, comes from the bottom of the valve on the beam assembly.
STEP 6: Install the log tray assemblies and the manual container to the beam. See FIGURE 10. 1. Lower the beam to horizontal position. Please refer to “Beam Operating Positions” section in Page 13. 2. Position the log tray frames onto the beam as shown below and secures with the M10 hardware loosely. 3. Tighten the M10 hardware using an 16mm wrench on the bolts, and a 17mm wrench on the lock nuts. 4. Attach the manual container to the beam with the M6 hardware using a cross head screwdriver.
(FIGURE11) STEP 9: Fill hydraulic oil. See FIGURE 12. The log splitter is shipped without hydraulic fluid in the reservoir. You must fill the reservoir before your initial use. 1. 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. The machine was tested by the manufacturer using AW32 oil, so that AW32 oil is highly recommended for most users in most areas. The reservoir tank has a capacity of 3.
4. Start the engine and use the control handle to engage the wedge to the farthest extended position and then retract fully. Repeat this operation for 12 cycles to repel the air trapped in the hydraulic system. Much of the fluid will be drawn into the cylinder and hoses. Stop the engine, and check the oil level as instructed below. NOTE: Make sure the oil level is above the bottom line on the dipstick. If not, refill the reservoir to prevent damage to the hydraulic pump. DO NOT overfill.
2. To place the beam in the Horizontal Position proceeds as follows: 1) Pivot the beam to the horizontal position. 2) The horizontal beam lock is self-locking. The spring loaded lock will snap into place when the beam is lowered into position. ● Check all nuts, bolts and hydraulic fittings are tight to be sure the equipment is in a safe working condition. ● Adjust handle release lever. Your log splitter is equipped with an external pressure release system which is attached under the valve bracket.
SECTION III: OPERATION INSTRUCTIONS • Start the engine as the instructions in the Engine Operator’s manual packed with your log splitter. • Grab the log on the sides and place it firmly on top of the beam against the end plate to split the wood in the direction of the grain. See FIGURE 16. • Use your right hand to push the control handle lever to the Forward position to split the wood. See FIGURE 16. The control handle has three positions. See FIGURE 15.
• Remove partially split wood from wedge. 1) If the log is clipped or jammed on the wedge, release the control handle and shut off the engine immediately. Gently knock off the log with a hammer or mallet (not with your hands). WARNING! Never remove partially split wood from the wedge with your hands. Fingers may become trapped between the split wood. 2) Once removed from the wedge, split the wood from the opposite end or in another location.
SECTION IV: MAINTENANCE OFF SEASON STORAGE If the log splitter will not be used for more than 30 days, prepare it for storage as follows: • Refer to the Engine Operator’s manual packed with your log splitter for information on the off-season storage of the engine. • Store unit in a clean, dry area. Do not store it next to corrosive materials, such as fertilizer. • Clean the log splitter thoroughly. Wipe the machine with an oiled rag to prevent rust, especially on the wedge and the beam. NOTES 1.
(FIGURE17) Spring Clip Locking Pin Latch Assembly Hitch Coupler Safety Chain NOTES 1. NEVER exceed 45 mph when towing your log splitter. Towing the log splitter at speeds higher than 45 mph could result in loss of control, damage to the equipment, or serious injury or death. 2. NEVER carry any cargo or wood on your log splitter. 3. NEVER allow anyone to sit or ride on your log splitter. 4. ALWAYS turn the engine to the “OFF” position before towing the log splitter.
MAINTENANCE & ADJUSTMENTS Regular maintenance is the way to ensure the best performance and long life of your machine. • Refer to the Engine Operator’s manual packed with your log splitter for all engine maintenance e.g. how to check and change the engine oil. • 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.
