When inserting drive shaft tube, hold the tube locking bolt outward preventing inside fitting from obstructing as well. Some models may come with the drive shaft already installed. When it is hard to insert drive shaft up to the marked position on the drive shaft tube, turn drive shaft by the cutter mounting end clockwise or counter-clockwise. Tighten tube locking bolt lining up the hole in the shaft tube. Then tighten clamp bolt securely (1). Installation of handle Remove the handle bracket (2) from the assembly. (Fig. 2) Place the handles and attach the handle bracket with four bolts lightly. Adjust to appropriate position. Then fix it firmly with the bolts. Fix protection tube on drive shaft or handle using cord clamps (3). (Fig. 3) If the protection tube is set apart from the handle or pipe, it will be caught by something during operation and it may cause serious injury. Do not set the protection tube apart from the handle or pipe. Throttle wire/stop cord Remove air cleaner cover. (Fig. 4) Loosen and remove the screw from the throttle wire holder. (Fig. 6) Connect the terminals of the stop cords coming out from the engine and shaft. (Fig. 5) Hook the throttle wire end on the throttle of the carburetor. Make sure that the throttle trigger shown in Fig. 17 has returned to the starting position. Put the throttle outer end into the groove, and then cover it with the throttle wire holder and fix the holder with the screw. (Fig. 7) Then, install the cleaner cover. Fix the protection tube which the stop cords and throttle wire are passing through, on the pipe with the hip pad. Then, as shown in the figure, fix the protection tube on the pipe and handle with the bands in the bag. After fixing, cut off the extra part of the band not to obstruct the operation. (Fig. 3) 17

18 If the protection tube is set apart from the handle or pipe, it will be caught by something during operation and it may cause serious injury. Do not set the protection tube apart from the handle or pipe. Some models may come with the parts pre-installed. Installation of blade guard (Fig. 9) The guard bracket already mounted to the drive shaft tube. Install the blade guard on drive shaft tube against angle transmission (4). Tighten the guard bracket firmly so that the blade guard does not swing or move down during operation. CAUTION The blade guard must be in place when operating. If the blade guard is not in place when operating, you may get the serious injury. Blade guards are equipped with sharp line limiter. Be careful with handling it. When attaching the guard extension to the blade guard, the sharp line limiter must be removed from the blade guard. To remove the guard extension, refer to the drawings. Wear gloves as the extension has a sharp line limiter, then push the two square tabs on the guard one by one in order after removed the screw. (Fig. 11) Installation of cutting blade (Fig. 12) When installing a cutting blade, make sure that there are no cracks or any damage in it and that the cutting edges are facing the correct direction. Align the notch hole of the cutter holder with the hole on the gear case (Top the gear case) and insert the Allen wrench to stop turning. Turn the fixing nut clockwise and remove the fixing nut, cutter holder cap, and toothed lock washers. The installation of the cutting blade is as follows: insert the Allen wrench into the notch hole of the cutter holder and the hole on the gear case. Then, install the cutting blade (check the installing direction, as referring to Fig. 14), the cutter holder cap and toothed lock washers onto the cutter holder in this order. Finally, tighten the fixing nut securely by turning counterclockwise with the Combi box spanner. (Fig. 12) CAUTION When installing the cutting blade, set its center hole to the convex part of the cutter holder and hold it with the concave surface of the cutter holder cap. Then, tighten the fixing nut to prevent the cutting blade from being eccentric. (Fig. 12) After installing the cutting blade, be sure to remove the Allen wrench and Combi box spanner. Before operation, make sure the blade has been properly installed. Cutter holder cap under a cutting blade, check it for wear or cracks before operation. If any damage or wear is found, replace it, as it is an article of consumption. The blade must be retained with a new cotter pin each time installed. (Fig. 12) Installation of nylon head (Fig. 15) Attach cutter holder (5) to the gear case. Insert an Allen wrench into the hole in the gear case to attach nylon head (6) by turning it clockwise. Since cutter holder cap is not used here, keep it for next metal blade use. OPERATING PROCEDURES Fuel (Fig. 16) WARNING The Brush cutter is equipped with a two-stroke engine. Always run the engine on fuel, which is mixed with oil. Provide good ventilation, when fueling or handling fuel. Fuel contains highly flammable and it is possible to get the serious personal injury when inhaling or spilling on your body. Always pay attention when handling fuel. Always have good ventilation when handling fuel inside building. Fuel Always use branded 89 octane unleaded gasoline. Use genuine two-cycle oil or use a mix between 25:1 to 50:1, please consult the oil bottle for the ratio or HITACHI dealer. If genuine oil is not available, use an anti-oxidant added quality oil expressly labeled for air-cooled 2-cycle engine use (JASO FC GRADE OIL or ISO EGC GRADE). Do not use BIA or TCW (2-stroke water-cooling type) mixed oil. Never use multi-grade oil (10 W/30) or waste oil. Always mix fuel and oil in a separate clean container. Always start by filling half the amount of fuel, which is to be used. Then add the whole amount of oil. Mix (shake) the fuel mixture. Add the remaining amount of fuel. Mix (shake) the fuel-mix thoroughly before filling the fuel tank. Fueling WARNING Always shut off the engine before refueling. Slowly open the fuel tank, when filling up with fuel, so that possible overpressure disappears. Tighten the fuel cap carefully, after fueling. Always move the Brush cutter at least 3 m from the fueling area before starting. Always wash any spilled fuel from clothing immediately with soap. Be sure to check any fuel leaking after refueling. Before fueling, clean the tank cap area carefully, to ensure that no dirt falls into the tank. Make sure that the fuel is well mixed by shaking the container, before fueling. Starting (Fig. 17) CAUTION Before starting, make sure the cutting attachment does not touch anything. 1. Slide ignition switch (7) to RUN position. (Fig. 17) Push priming bulb (10) several times so that fuel flows through return pipe. (Fig. 18) 2. With the safety trigger (8) (if so equipped) pressed, pull throttle trigger and push throttle lock (9). Then slowly release the throttle trigger first, then the safety trigger. This will lock the throttle in starting position. 3. Set choke lever to START position. (Fig. 19) 4. Pull recoil starter briskly, taking care to keep the handle in your grasp and not allowing it to snap back. (Fig. 20) 5. When you hear the engine want to start, return choke lever to RUN position (open). Then pull recoil starter briskly again. If engine does not start, repeat procedures from 2 to 5. 18

19 6. After starting engine, pull throttle trigger to release throttle lock. Then allow the engine about 2 3 minutes to warm up before subjecting it to any load. Cutting (Fig. 21, 22, 23) When cutting, operate engine at over 6500 rpm. Extended time of use at low rpm may wear out the clutch prematurely. Cut grass from right to left. Blade thrust may occur when the spinning blade contacts a solid object in the critical area. A dangerous reaction may occur causing the entire unit and operator to be thrust violently. This reaction is called blade thrust. As a result, the operator may lose control of the unit which may cause serious or fatal injury. Blade thrust is more likely to occur in areas where it is diffi cult to see the material to be cut. Wear the harness as shown in the figure. The blade turns counter-clockwise, therefore, be advised to operate the unit from right to left for effi cient cutting. Keep onlookers out of working area at least 15 m. Press the quick release button or pull emergency release flap in the event of emergency. (Fig. 24) How to use the shoulder harness Wear the shoulder harness on your shoulder as shown Fig. 22 and hook it on the hanger of the machine. Adjust the length of the shoulder harness to the most comfortable position. (Fig. 22) To remove the machine from the shoulder harness, hold the main pipe of the machine firmly by one hand and then remove the hook (11) of the shoulder harness from the hunger (12). (Fig. 24-a) How to reinstall the hook after using the emergency release pinch It needs to go through the buckle (13) of the hook (11) to the metal plate (14) on the harness and go through the plate (15) of the emergency release pinch to the metal plate (14) on the harness. (Fig. 24-b) After installing the buckle onto the harness, pull the hook (11) and make sure the hook (11) is securely fixed on the harness, then hook it to the hunger (12). (Fig. 24-a) WARNING When using the machine, wear the shoulder harness and hold the machine correctly with both hands. If you feel that there is something dangerous, separate the brush cutter from your body by pulling the emergency release pinch (11) of the harness to the direction of the arrow showing on Fig. 24-a. If cutting attachment should strike against stones or other debris, stop the engine and make sure that the attachment and related parts are undamaged. When grass or vines wrap around attachment, stop engine and attachment and remove them. If you pull the emergency release pinch without holding the machine, the machine will fall to your feet. Pull the emergency release pinch as holding the main pipe of the machine by one hand. Before operation, make sure that the emergency release pinch on the shoulder harness is working properly. Stopping (Fig. 25) Decrease engine speed and run at an idle for a few minutes, then turn off ignition switch (7). WARNING A cutting attachment can injure while it continues to spin after the engine is stopped or power control is released. When the unit is turned off, make sure the cutting attachment has stopped before the unit is set down. How to use nylon head When cutting, operate engine at over 6500 rpm. Extended use at low rpm may wear out the clutch prematurely. This product is designed so that it will stop cutting when the nylon line becomes 16 cm or longer. WARNING A cutting attachment can injure while it continues to spin after the engine is stopped or power control is released. When the unit is turned off, make sure the cutting attachment has stopped before the unit is set down. Set the engine speed as low as possible and tap the Head on the ground. (Fig. 26) Also, you can extend nylon line with hands but the engine must be completely stopped. (Fig. 27) Adjust nylon line to proper length cm before each operation. MAINTENANCE MAINTENANCE, REPLACEMENT OR REPAIR OF THE EMISSION CONTROL DEVICES AND SYSTEMS MAY BE PERFORMED BY ANY NON-ROAD ENGINE REPAIR ESTABLISHMENT OR INDIVIDUAL. Carburetor adjustment (Fig. 28) WARNING The cutting attachment may be spinning during carburetor adjustments. Never start the engine without the complete clutch cover and tube assembled! Otherwise the clutch can come loose and cause personal injuries. In the carburetor, fuel is mixed with air. When the engine is test run at the factory, the carburetor is basically adjusted. A further adjustment may be required, according to climate and altitude. The carburetor has one adjustment possibility: T = Idle speed adjustment screw. Idle speed adjustment (T) Check that the air filter is clean. When the idle speed is correct, the cutting attachment will not rotate. If adjustment is required, close (clockwise) the T-screw, with the engine running, until the cutting attachment starts to rotate. Open (counter-clockwise) the screw until the cutting attachment stops. You have reached the correct idle speed when the engine runs smoothly in all positions well below the rpm when the cutting attachment starts to rotate. If the cutting attachment still rotates after idle speed adjustment, contact a HITACHI dealer. Standard Idle rpm is rpm. WARNING When the engine is idling the cutting attachment must under no circumstances rotate. Air filter (Fig. 29) The air filter must be cleaned from dust and dirt in order to avoid: Carburetor malfunctions. Starting problems. Engine power reduction. Unnecessary wear on the engine parts. Abnormal fuel consumption. 19

20 Clean the air filter daily or more often if working in exceptionally dusty areas. Cleaning the air filter Remove the air filter cover and the filter (17). Rinse it in warm soap suds. Check that the filter is dry before reassembly. An air filter that has been used for some time cannot be cleaned completely. Therefore, it must regularly be replaced with a new one. A damaged filter must always be replaced. Fuel filter (Fig. 30) Drain all fuel from fuel tank and pull fuel filter line from tank. Pull filter the element out of the holder assembly and rinse the element in warm water with detergent. Rinse thoroughly until all traces of detergent are eliminated. Squeeze, do not wring, away excess water and allow the element to air dry. If element is hard due to excessive dirt buildup, replace it. Spark plug (Fig. 31) The spark plug condition is influenced by: An incorrect carburetor setting. Wrong fuel mixture (too much oil in the gasoline). A dirty air filter. Hard running conditions (such as cold weather). These factors cause deposits on the spark plug electrodes, which may result in malfunction and starting diffi culties. If the engine is low on power, diffi cult to start or runs poorly at idling speed, always check the spark plug first. If the spark plug is dirty, clean it and check the electrode gap. Readjust if necessary. The correct gap is 0.6 mm. The spark plug should be replaced after about 100 operation hours or earlier if the electrodes are badly eroded. Muffler (Fig. 32) Remove the muffl er and clean out any excess carbon from the exhaust port or muffl er inlet every 100 hours of operation. Cylinder (Engine cooling) (Fig. 33) The engine is air cooled, and air must circulate freely around the engine and over the cooling fins on the cylinder head to prevent overheating. Every 100 operating hours, or once a year (more often if conditions require), clean fins and the external surfaces of engine of dust, dirt and oil deposits which can contribute to improper cooling. Do not operate the engine with the engine shroud or muffl er guard removed as this will cause overheating and engine damage. Angle transmission (Fig. 34) Check angle transmission or angle gear for grease level about every 50 hours of operation by removing the grease filler plug on the side of angle transmission. If no grease can be seen on the flanks of the gears, fill the transmission with quality lithium based, multipurpose grease up to 3/4. Do not completely fill the transmission. Blade WARNING Wear protective gloves when handling or performing maintenance on the blade. (Fig. 35) Use a sharp blade. A dull blade is more likely to snag and thrust. Replace the fastening nut if it is damaged and hard to tighten. When replacing the blade, purchase one recommended by HITACHI, with a 25.4 mm fitting hole. 20 When installing saw blade, always face the stamped side up. 3-tooth blades can be used with either side facing up. Use the correct blade for the type of work. When replacing blades, use appropriate tools. When cutting edges become dull, re-sharpen or file as shown in figure. Incorrect sharpening may cause excessive vibration. Discard blades that are bent, warped, cracked, broken or damaged in any way. When sharpening blades it is important to maintain the original shape of the radius at the base of the tooth to avoid cracking. Nylon head Nylon line replacement Remove the cutting body cap by pushing inward the locking tabs on the side of the nylon head (Fig. 36). Take out the spool, hook the new nylon line into the hole of the spool, then wind it around the spool in two stages (Fig. 37). When the nylon line has been wound around the spool, temporarily fasten it in the opening of the spool at about 10 cm from the end. (Fig. 38) Then thread the nylon line through the hole on the side of the nylon head and place the cutting body cap in reverse order of the cap removal. Pull the right and left nylon lines until they are secured about cm from the end. (Fig. 41) The nylon head is designed for nylon lines with an outer diameter of 2.4 mm. Do not use nylon lines with a different outer diameter. Make sure that the right and left nylon lines are of equal length since vibrations will otherwise increase. Maintenance schedule Below you will find some general maintenance instructions. For further information please contact a HITACHI dealer. Daily maintenance Clean the exterior of the unit. Check that the harness is undamaged. Check the blade guard for damage or cracks. Change the guard in case of impacts or cracks. Check that the cutting attachment is properly centred, sharp, and without cracks. An off-centred cutting attachment induces heavy vibrations that may damage the unit. Check that the cutting attachment nut is suffi ciently tightened. Make sure that the blade transport guard is undamaged and that it can be securely fitted. Check that nuts and screws are suffi ciently tightened. Weekly maintenance Check the starter, especially cord and return spring. Clean the exterior of the spark plug. Remove it and check the electrode gap. Adjust it to 0.6 mm, or change the spark plug. Clean the cooling fins on the cylinder and check that the air intake at the starter is not clogged. Check that the angle gear is filled with grease up to 3/4. Clean the air filter. Monthly maintenance Rinse the fuel tank with gasoline. Clean the exterior of the carburetor and the space around it. Clean the fan and the space around it.
