1. 80 90W The first time the oil need to be replenished after 100 hours of use after that it will be every 300 hours or once a year The main gearbox is mounted on the MFrame and drives all the 3 different heads Check the oil level at this pl in the middle at the front Fill or add oil through this plug At the bottom there is a plug to drain the oil The second gearbox is located on top of the rear MT head and drives only the rear head The oil level sit at the rear side This is the same plug to drain and fill the oil 7 4 COG BELT TENSION amp REPLACEMENT The toothed belt cog belt tension is very important It determines the life time and the power it can transmit Each individual head has its own toothed belt who have to be checked independently The easiest way to figure out if the belt tension is right is by putting a pin d 5 mm through the hole in the side of the cog belt housing if it isn t there remove the top cover and work from the inside If a force of 90 N 20 Ibs is applied halfway the belt side the belt should move 4 8 mm 0 19 That works in both directions in or out as long as the force is applied square to the belt Maredo is working on a precision tension measuring tool to easily check the belt tension When this tool will be available we will update you For now it has to be done as described above If you need to adjust the belt tension first push the PTO extension cover back Next l2. for this MAREDO machine The way to calculate the correct length goes as Loa A connect the MAREDO machine to the tractor in the 3 Point linkage B Adjust the top link so the Aframe is vertical C Move the tractor 3P hitch up and down and find the position at which the PTO shaft is the shortest in length D Fix the 3 Point hitch at this position and secure the machine tractor E Measure the orange length between the two PTO shafts from groove groove L1 F Next measure the length of the PTO drive shaft from secure pin to secure pin with the shaft fully in L2 G If L2 1s at least 50 mm or 2 less than L1 no action is required If not take the PTO shaft apart and each PTO half steel tube and plastic cover must be shortened L2 L1 50 mm or 2 if you work in inches with L1 and L2 H Example We measured L1 500 mm 20 and L2 600 mm 24 L2 is more than L1 so we need to cut it by L2 L1 50 mm 600 500 50 150 mm or 24 20 2 6 I Deburr all the parts fix the PTO and mount the PTO shaft to the MAREDO machine He is ready for usage now 6 0 FIRST JOB PREPARATION IMPORTANT NOTES 6 1 TOPLINK amp 3 POINT LINKAGE SETTINGS At the top of the Aframe we have 3 holes for the top link If an higher one is chosen the MAREDO machine will be tilted more forwards when raised Which means more clearance for the rear head A clearance of at least 200 mm 8 is needed for a sa
