Improper mounting can cause hazards during use of the forest crane. Mounting, carried out in a manner other than specified in this manual, can expose the user to danger and will void the manufacturer s warranty 5.1 MOUNTING FOREST CRANE TO BMF TRAILERS Mounting of forest crane should be performed at the dealer service center or by person authorized by the manufacturer or dealer. Mounting/detaching the crane can also be made by end user, if professional equipment is used, all safety regulations are followed and at least one qualified mechanic is in present during all the mounting/detaching process. Strength class for mounting bolts of slewing device-support legs (fig. up) and support legs to trailer (fig down) has to be 10.8 (DIN912). Use self-locking nuts M20. The tightening torque for the mounting bolts of the crane and supporting legs is 660 Nm. Retighten bolts after the test run and after first 8 hours of use! Check after 40 working hours, tighten if needed. Later on do visual check.

5.2 MOUNTING CONTROL VALVE The valve must be installed in the way that levers cannot be used inadvertently! Install the valve at desired location using the included bracket. Leave enough space for hoses to avoid risk of abrasion or clamping while working with forest crane. Hoses in the operator s cabin must be covered in the way that the user is protected from the direct oil jets in case of hose breakage! 6 HYDRAULIC SYSTEM BMF 850 Forestcrane Page 6 of 14 All BMF forest crane control valves are fitted with the oneway flow valve, which protects control valve in case return line is by mistake connected to pressure line. If pump is directly connected to cranes control valve return line, there will be danger of breaking pump or hoses from overpressure, because one-way flow valve will block oil flow in wrong direction 6.2 HYDRAULIC DIAGRAM AND CONTROL FUNCTIONS 6.1 CONNECTION Before connecting forest crane to the tractor s hydraulic system, make sure that the oils are compatible. Forest crane has been tested using HLP 46 hydraulic oil. Check the hydraulic oil level. We recommend connecting the pressure hose to the single-acting hydraulic outlet and the return hose to the tank via the return filter. The filter s intended minimum flow rate is 30-50 l/min and the filtering density is 10-50 μm. Make sure you connect the return hose always first and disconnect it last. Make sure the connection has made properly. Ensure, that the control valve s pressure line (P) has been connected properly and that the return line (T) is unobstructed. In case there is obstruction in return line (quick couplings are not connected or are not locked properly) the pressure might rise over 10 bar and cause malfunction of control valve Forest crane can also be connected to the doubleacting hydraulics outlet. If this option will be used make sure, that the lever of the double-acting valve is in the right position and the pressure is directed to the pressure connection of the crane s control valve. Check also vehicle s operating manual for hydraulic system connecting instructions. Figure 4 Hydraulic diagram with on/off controlvalve

Note that the hydraulic seals, hoses and steel structures are prone to damage at low temperature. When starting work at cold temperature, first let the oil flow freely through the valve for a couple of minutes. The maximum operating temperature for hydraulic oil is +75 C. Drive through every movement with an unloaded crane, paying attention to the positions in which the crane might hit surrounding obstacles. Support legs (both directions) 180 3,6 Never move the boom to its extreme position at full speed! 7 OPERATING INSTRUCTIONS 7.1 TESTING Ensure that the control valve s levers are in the middle position. Switch on the pump and let oil flow through the valve for a while. Lower the support legs. Ensure that there are no people or obstacles in the operating area. The danger zone is 20 m! Carefully drive crane movements one by one in the way, that all cylinders reach their extreme positions and repeat this until all movements are smooth. Be careful when getting air out of system. If you drive cylinder to its extreme position at full force, the air pressure in the cylinder will damage the seals! Be extremely careful, when there is air in the cylinders! After testing forest crane, inspect connections and repair leaks if any appeared. Check the mounting bolts of the crane and support leg, tighten them if necessary. Check the hydraulic oil level, and fill up if necessary. Move the control levers smoothly and stoutly, avoiding quick and jerky movements. Learn to use several functions simultaneously. Start at low engine speed to avoid sudden movements. After you have become accustomed to the crane s movements, choose appropriate engine speed so, that operation is smooth and efficient, but you still have the movements under control. Loading big and heavy logs from distance, keep load close to the ground. When reaching the trailer, lift it up to load. When unloading do vice versa. Working on inclined surface, do not operate with the full lifting torque and be extremely careful. Loading uphill note, that turning crane with too much load might cause the oil pressure in slewing device cylinders to reach critical point, where shock valve has to intervene. This could make slewing device uncontrollable and crane might turn back to downhill direction in a way that it might fall over. In such case lower the load as close to ground as possible, but not too rapidly. Use the support legs only for purpose to provide additional support for the vehicle! Don t forget to lift the support legs UP before moving to another place!

Support legs are equipped with extra valves, which will keep them in working position in case feeding hoses of support leg cylinder breaks Do not exceed the speed limit when driving! Adjust speed according to the road and weather conditions. Be especially careful on turns! For driving always attach crane by grapple to trailers frame. When driving with load, leave one log sticking out from pile and attach crane by grapple to it. Keep crane boom as low as possible.
