INSTRUCTIONS FOR OPERATING

INSTRUCTIONS - MOTOR Please follow the motor manufacturer's operating instructions. After starting: Adjust the accelerator lever slowly into a position between START and STOP which you consider to be suitable operating speed. To switch on cutter bar. To switch on drive mechanism. DANGER: When mowing beware of foreign bodies and impediments. If you should suddenly run into an unexpected impediment when mowing, please switch of operating levers immediately. Stop cutter bar. After mowing for a short time switch the mower off and check that all nuts and bolts are tight. Only mow with a sharp cutting edge and correct adjustment of all blades. To stop: Put the accelerator lever into STOP position. HOW TO MOUNT THE ACCELERATOR WIRE (Fig. 2) Position the lever (1) on the engine at the end of its stroke as shown by arrow "A,, in the gure. Move the throttle lever (2) on the handlebar to the end of its stroke as shown by arrow "B,, in the gure. Insert wire (3) into hole (4), secure the sheath (5) with retainer (6) and screw (7). ATTENTION: in the position "stop,, the throttle lever must stop engine. BELT STRETCHER DRIVING WIRE (Fig.5) Driving wire is already connected with the belt-stretching spring; have it connected to the lever on handlebar as follows: Insert the wire (3) and the register (4) in hole cut in the prong. Engage sheath terminal (1) into hole (2). ASSEMBLING OF THE CUTTER BAR (Fig.10-14) For models equipped with 87 cm. cutting bar please complete the assembly adding the missing sliding part ( part. 2 – g. 10) you can nd in the accessories envelope. In order to x it please use the 2 screws ( part 1) , the washers and the nuts you can nd on the cutting bar. Please refer also to chapter : “ how to adjust the cutting bar height”. To x part (7) with the parts (5, 6) to the (8). Fix the part (10) with the parts (1, 2 and 3) to the (8). After about 2 hours of work to tighten the screws (5). CORRECT ASSEMBLY OF THE BOWDEN ROD, ENGINE FUEL REGULATION (Fig. 3-4) Insert the opposite end of the Bowden rod down into the engine fuel lever. Now lightly clamp the jacketed end of the rod. Set the fuel lever on the handlebar to the start position

GBthen set the fuel lever on the engine to the start position, right up to the stop point. Following this, denitively x the jacketed end of the rod. Take care to prevent the rod from bending during the assembly phase. If the fuel lever fails to move freely, lubricate the rod with a few drops of oil and wait a few minutes to allow the oil to penetrate the casing. Now operate the fuel lever again. ASSEMBLY OF THE CUTTING BAR TO THE UNIT (Fig. 6) The motor mower has a coupling for quick and easy attachment of the cutter bar and other accessories. The motor should be shut down and the machine horizontal. Insert the cutter bar pin (1) halfway into its seating (2). Install the belt (3) in its pulley by moving the guide pin all the way to the end of its travel. Attach the springs to their hooks (5), then to the holes (7). Replace the cowling (6) with its centering pin. Tighten home the nut with its washer on the cowling. POSITIONING THE CUTTER BAR DRIVE BELT (Fig. 7) To increase the tension on the cutter bar drive belt between the machine and the attachment, set the register (2) so that the cutter bar will only begin to move when the control lever is over the halfway mark in its travel. Pull the left operating lever (1): forward drive. BELT-STRETCHER CONTROL ADJUSTMENT (Fig. 8) Warning - Tyres should start rotating only when control lever is beyond halftravel; When lever is pulled to full extent (working position), the beltstretcher load spring (2) should extend by 6 to 8 mm approx. For above de- scribed conditions be reached, action is to be taken on nut (1 ) set close to the belt stretcher control assembly. CUTTER BAR HEIGHT ADJUSTMENT (Fig. 10) Having to mow on uneven soils, you must adjust the cutter bar height. Proceed as follows: - Unloose nut (1), shift sliding block (2) in desired position, tighten nut (1). Perform this step on both sliding blocks. REGULATING THE KNIFE (Fig. 9) After changing knife or after a certain number of work hours, the knife guide should be regulated by means of screws (1) and their locknut. To check the results after each regulation, rst remove the cowling and then turn pulley (2) slowly by hand and check to make sure that the knife is moving easily. MAINTENANCE Air lter This should be carried out in accordance with the attached motor maintenance instructions. GEARBOX (Fig. 11) Lube oil: SAE 80. The needed quantity for oil is about 0,18 lt. Check oil level before starting engine. Oil level should he checked by unscrewing the cap on the side of box. Check oil level every 60 hours of work. CUTTER BAR TRANSMISSION (Fig. 12) Two greasing points (1-2). Important! Clean and grease blade bar and all moving parts every time after use. MAINTENANCE OF THE CUTTER BAR The cutting mechanism is one ot those pieces of agricultural equipment, which is placed under the most stress. It is abvious, therefore, that it must be particularly carefully serviced and correctly adjusted. It is advisable to clean the cutting mechanism after each use. To do this the cutting edge must be removed so that the dirt which has collected between the blades and cutting bars can be completely removed. Should the cutter bar not be in use for a longer period of time it should be sprayed with an anticorrosive agent. Although all

GBtypes of bar cutting mechanism are by and large resistant to the interference of stones and similar objects, it can occasionally happen that the bars and blades become damaged or bent. It is necessary, therefore, to check the condition of these parts each time you sharpen the cutting blade - after 4-6 hours of mowing depending on the work load. Any damage must be made good and bent bars or blades repaired. Only well aligned bars and blades can guarantee a clean cut. At this point the track directions of the cutting edges should also be checked and too much play in the direction be removed by means of adjustment. lmportant when adjusting the directions of the cutting edges- adjust one direction rst and then the second. After the adjustment of each single direction the blade must be able to be freely moved to and fro by hand. Please pay attention to the following particualr instructions!!! SHARPENlNG THE CUTTlNG BLADE (Fig. 13) When the cutting blades are blunt (this will depend on work load) they must be re- ground. In order to do this, the cutting blade is removed from the bar and cleaned. It is essential to check whether the backs and edges of the blades are bent; if so, they must be re-aligned. Only then can sharpening begin. Suitable for this purpose is a hand grinder with about 15000 - 20000 revolutions per minute, in conjunction with a cup-shaped grinding point with a diameter of 25 mm and a length of about 35 mm. Only the front side (face) of the grinding point is used in grinding - in a movement from the back of the blade to the bladeís edge. Cutter bar blades need a cutting angle of 35 - 40°. CUTTING BLADE REPLACEMENT (Fig. 16) Unscrew (1), take the blade coupling out (2) and then remove the blade. To reassemble the blade, perform these operations backwards. Note - To achieve good cutting, blade must always be sharp.
