Anleitung Zusammenfassung
Slide coupling half into place while guiding three mounting bolts through holes in pump support bracket. 10. Secure with nuts and washers removed earlier. 12 11. Set .010 to .060 inch clearance between the nylon “spider” and the engine coupling half by sliding a matchbook cover between the nylon “spider” and the engine coupling half and moving pump coupling half as needed. Secure pump coupling half with set screw. See figure 16. NOTE: Make certain proper clearance is obtained before tightening set screw. 12. Reattach spark plug wire to spark plug. PUMP TIRES Recommended operating tire pressure is 12 to 15 p.s.i. (sidewall of tire may give tire manufacturer’s recommended pressure). Maximum tire pressure under any circumstances is 30 p.s.i. Equal tire pressure should be maintained on all tires. When installing a tire to the rim, be certain rim Is clean and free of rust. Lubricate both the tire and rim generously. Never inflate to over 30 p.s.i. to seat beads. A WARNING: Excessive pressure (over 30 p.s.i.) when seating beads may cause tire/ rim assembly to burst with force sufficient to cause serious injury. OFF-SEASON STORAGE If the log splitter will not be used for a period longer than 30 days, the following steps should be taken to prepare the log splitter for storage. 1. Clean the engine and the entire log splitter thoroughly. 2. Refer to the engine manual for correct engine storage instructions. Follow instructions carefully. 3. Wipe unit with an oiled rag to prevent rust, especially wedge and beam. NOTE: When storing any type of power equipment in an unventilated or metal storage shed, care should be taken to rustproof the equipment by coating with a light oil or silicone. 4. The tongue can be removed and reattached in an upright position as shown in figure 17 to take less space when storing. 5. Store unit in a clean, dry area. Block the wheels. Do not store next to corrosive materials, such as fertilizer. FIGURE 17. 13 I HOW YOUR LOG SPLITTER OPERATES Cylinder y^ a Cylinder Breather Directional Valve Relief Valve pj|Qt Pressure Line Reservoir High Volume Low Pressure Gear Section Pump Low Volume High Pressure Gear Section THE PUMP A two-stage log splitter pump has one large and one small gear section, using common inlet and outlet ports. Below a preset pressure (called unloadi lg pressure) a check valve between the two gear sections allows both flows to combine. Together, the t no gear sections create a large volume flow which p-oduces rapid cylinder movement under low load condi ions. Above unloading pressure, a pilot pressure lin<3 (which simulates actual pressure at the cylinder) activates the unloading valve, which causes the flow to bypass the large gear section and return to the pump in et area. The small gear section is now operating alone, and will generate the higher pressure necessary for the actual log splitting operation. The original factory setting for the unloading valve is designed to provide maximum flow while remaining below engine stalling load. Note: Splitting capability is not affected by the setting of the unloading valve. Do not attempt to adjust or reset it without a pressure gauge (should be performed by an authorized service dealer only). THE DIRECTIONAL VALVE AND CYLINDER From the pump, oil flows to a four way, three position directional valve. At the neutral position th s valve directs the flow back to the oil reservoir, bypassing the cylinder. When the directional valve is directing the flow to the back of the cylinder, the cylirder rod extends quickly until it meets significant res ¡stance. Upon reaching unloading pressure, movement of the shaft will slow but will continue forward. If the pressure reaches a preset maximum (called relief valve pressure) the relief valve, located within the directional valve, will allow the flow to bypass the cylinder and return to the reservoir. This can happen when the cylinder rod meets excessive resistance, or when it reaches the end of its stroke and can move no farther. NOTE: Never operate at relief valve pressure for more than a few seconds. When the directional valve is directing the flow to the front of the cylinder, the rod will retract quickly since it is encountering no resistance. The relief valve will momentarily bypass the flow at the end of the return stroke but the directional valve should then automatically return to the neutral position, directing the flow directly into the reservoir. This serves to protect the pump from possible damage due to prolonged operation at relief valve pressure. Because of the potential for system damage, the relief valve is carefully and precisely preset by the manufacturer. NOTE: The user should not attempt to adjust or change the setting of the relief valve. OPERATIONAL PROBLEMS If you have trouble with your log splitter, please refer to the Hydraulic Trouble Shooting Guide. NOTE: Readjustment of valves or disassembly of pump should be performed b...
