Never use wire or wire ropes. They can break off and become a dangerous projectile. OPERATING PROCEDURES Fuel (Fig. 20) WARNING The trimmer 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 filing 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. Cutting (Fig. 26, 27, 28) ○ 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. ○ Cut grass from left to right (only curve shaft model). ○ 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 difficult to see the material to be cut. ○ Wear the harness as shown in the figure (if so equipped). The blade turns counter-clockwise, therefore, be advised to operate the unit from right to left for efficient cutting. Keep onlookers out of working area at least 15 m. NOTE Press the quick release button or pull emergency release flap (If so equipped) in the event of emergency. (Fig. 27-1) WARNING 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. Stopping (Fig. 29, 30) Decrease engine speed and run at an idle for a few minutes, then turn off ignition switch (24). For models with an engine ignition switch, keep the ignition switch pressed until the engine comes to a complete stop. 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. Fueling ○ ○ ○ ○ ○ ○ WARNING Always shut off the engine before refueling. Slowly open the fuel tank, when filling up with fuel, so that possible over-pressure disappears. Tighten the fuel cap carefully, after fueling. Always move the trimmer at least 3 m from the fueling area before starting. Always wash any spilled fuel from clothing immediately with soap. Be sure to check for any fuel leakage after refueling. Semi-auto cutting head ○ 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. ○ Cut grass from left to right (only curve shaft model). 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. 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 CAUTION Before starting, make sure the cutting attachment does not touch anything. 1. Set ignition switch (24) to ON position. (Fig. 21, 22) * Push priming bulb (25) several times so that fuel flows through return pipe (39). (Fig. 23) 2. Set choke lever (27) to CLOSED position (A). (Fig. 24) 3. Pull recoil starter briskly, taking care to keep the handle in your grasp and not allowing it to snap back. (Fig. 25) 4. When you hear the engine want to start, return choke lever to RUN position (open) (B). Then pull recoil starter briskly again. NOTE If engine does not start, repeat procedures from 2 to 5. 5. Then allow the engine about 2–3 minutes to warm up before subjecting it to any load. Automatically feeds more nylon cutting line when it is tapped at low rpm (not greater than 4500 rpm). 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. 31) 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. ○ 12 000Book_TCG22EAS_WE.indb 12 2012/10/22 18:09:16 English 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. Flexible drive shaft (Fig. 35) Flexible drive shaft should be removed and lubricated with good quality lithium grease every 20 hours. To remove the flexible shaft, first remove screw (29), loosen bolt (30) and remove the gear case then pull the shaft out of the drive shaft pipe. Clean the shaft off and apply a generous coat of lithium grease to it and insert if back into the drive shaft pipe, turn it unit it drops into place then install the gear case, install & tighten screw (29) and screw (30). If the cutting attachment still rotates after idle speed adjustment, contact your Hitachi dealer. Angle transmission (Fig. 36) 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. NOTE ○ Standard Idle rpm is 2800-3200 rpm. WARNING When the engine is idling the cutting attachment must under no circumstances rotate. Air filter (Fig. 32) 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 Clean the air filter daily or more often if working in exceptionally dusty areas. Cleaning the air filter Open the air filter cover and the filter (28). 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. 33) Drain all fuel from fuel tank and pull fuel filter line from tank. Pull filter element out of holder assembly and rinse element in warm water with detergent. Rinse thoroughly until all traces of detergent are eliminated. Squeeze, do not wring, away excess water and allow element to air dry. NOTE If element is hard due to excessive dirt buildup, replace it. Spark plug (Fig. 34) 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 difficulties. If the engine is low on power, difficult 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. Re-adjust 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. NOTE In some areas, local law requires using a resistor spark plug to suppress ignition signals. If this machine was originally equipped with resistor spark plug, use same type of spark plug for replacement. Semi-auto cutting head Nylon line replacement (1) Remove the case (31) by firmly pushing inward the locking tabs with your thumbs as shown in Fig. 37. (2) After removing the case, take out the reel and discard the remaining line. (3) Fold the new nylon line unevenly in half as shown in picture. Hook the U-shaped end of the nylon line into the groove (32) on the center partition of the reel. Wind both halves of the line on the reel in the same direction, keeping each half of the line on its own side of the partition. (Fig. 38) (4) Push each line into the stopper holes (33), leaving the loose ends approx. 10 cm in length. (Fig. 39) (5) Insert both loose ends of the line through the cord guide (34) when placing the reel in the case. (Fig. 40) NOTE When placing a reel in the case, try to line up the stopper holes (33) with the cord guide (34) for easier line release later. (6) Place the cover over the case so that the cap locking tabs (35) on the case meet the long holes (36) on the cover. Then push the case securely until it clicks into place. (Fig. 41) (7) The initial cutting line length should be approx. 11–14 cm and should be equal on both sides. (Fig. 42) Blade (Fig. 43) WARNING Wear protective gloves maintenance on the blade. ○ ○ ○ ○ ○ ○ ○ when handling or performing 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 blade, purchase one recommended by Hitachi, with a 25.4 mm (one inch) fitting hole. When installing a saw blade (38), always face the stamped side up. In the case of a 3 or 4 tooth blade (37), it can be used on either side. 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 the illustration. Incorrect sharpening may cause excessive vibration. Discard blades that are bent, warped, cracked, broken or damaged in any way. NOTE When sharpening blade it is important to maintain an original shape of radius at the base of the tooth to avoid cracking. Maintenance schedule Below you will find some general maintenance instructions.
