Insert the hex bar wrench (20) into the hole of the gear case and groove of the cutter holder (A) (21) in order to lock the shaft. Install cutting head on gear case of grass trimmers/brush cutters. The mounting nut is left-hand-threaded. Turn clockwise to loosen/counter-clockwise to tighten. NOTE Since the cutter holder cap is not used here, keep it for when a metal blade is used, if so equipped.

4. Adjusting line length

Set the engine speed as low as possible and tap the head on the ground. The nylon line will be drawn out about 3 cm with each tap. (Fig. 13) Also, you can extend the nylon line by hand but the engine must be completely stopped. (Fig. 14) Adjust the nylon line to the proper length of 11–14 cm before each operation. Installation of cutting blade (Fig. 15) (If so equipped) Insert the hex bar wrench (20) into the hole of the gear case and groove of the cutter holder (A) (21) in order to lock the shaft. Assemble in the following order: Cutter holder (A) (21), blade (22), cutter holder (B) (23), nut cover (24). Tighten the fi xing nut with the combi box spanner with a tightening torque of 14 ± 2 N

Please note that the cutter fi xing nut (25) has left-handed threads (clockwise to loosen/ counter-clockwise to tighten). NOTE ○ When installing cutter holder (B) (23), be sure to set concave side upward. ○ When installing or removing a blade, make sure to wear gloves and place the blade cover over the blade. CAUTION Check a nut cover (24) for wear or cracks before operation. If any damage or wear is found, replace it, as it is an article of consumption. WARNING ○ 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. ○ Remove any surface grit from blade installation fi ttings (cutter holder (A) (21), cutter holder (B) (23), nut cover (24), nut (25)). Failure to do so may result in the loosening of nuts. ○ The protrusion of the cutter holder (A) (21) may become misaligned with the blade (22) while tightening nut (25). Before operation, make sure the blade has been properly installed. (Fig. 16) ○ Rotate the blade by hand and make sure there is no rocking or abnormal noise. Rocking may cause abnormal vibrations or result in the loosening of nuts. OPERATING PROCEDURES Engine oil Always use the specifi ed engine oil (multigrade oil of classifi cation SAE 10W-30). Insuffi cient engine oil or using engine oil other than the specifi ed type may cause breakdown of the unit. Filling up with engine oil ○ Place the unit horizontally on a clean, fl at surface. ○ Remove the oil cap and check whether the engine oil comes up to the mouth of the oil tank opening. (Fig. 17) ○ If the oil level is low or when using the unit for the fi rst time, fi ll the tank with engine oil up to the mouth of the oil tank opening. ○ If the engine oil is conspicuously dirty or discolored, change the oil. ○ Tighten the oil cap securely after fueling. ○ When using the unit for the fi rst time, change the engine oil after running the engine for approximately 10 hours. Subsequently, change the oil after every 50 hours of operation. CAUTION ○ To avoid the risk of burn injuries, allow the engine to cool thoroughly before changing the engine oil. ○ To prevent breakdown, ensure that no sand or dirt gets into the tank while refueling. Fuel WARNING ○ Provide good ventilation, when fueling or handling fuel. ○ Fuel contains highly fl ammable 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. ○ Always use branded 89 octane unleaded gasoline. ○ Do not use a mixture of gasoline and engine oil as this may lead to starter failure or power reduction. Fueling WARNING ○ Always shut off the engine and let it cool for a few minutes before refueling. Do not smoke or bring fl ames or sparks near the fueling site. ○ Slowly open the fuel tank, when fi lling up with fuel, so that possible over-pressure disappears. ○ Tighten the fuel tank cap carefully, after fueling. ○ Always move the unit 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 leakage after refueling. ○ Before fueling, in order to remove static electricity from the main body, the fuel container and the operator, please touch the ground that is slightly damp. Before fueling, clean the tank cap area carefully, to ensure that no dirt falls into the tank. Starting WARNING ○ Before starting the tool, ensure that the cutting attachment is not touching any objects or the ground. Otherwise, the cutting attachment may unexpectedly rotate and cause an injury. ○ Ensure that the cutting attachment does not rotate while the engine is idling. If it does rotate, adjust the idle speed according to the instructions in “Idle speed adjustment” in the “MAINTENANCE” section. If the cutting attachment still rotates after this adjustment, immediately stop the engine and cease use, then bring the tool to the nearest HiKOKI Authorized Service Center. (1) Starting the cold engine

1. Set ignition switch (26) to ON position. (Fig. 18)

2. Push priming bulb (27) several times so that fuel fl ows

through return pipe (28). (Fig. 19)

3. Set choke lever (29) to START position (closed) (A).

4. Pull recoil starter briskly, taking care to keep the handle

in your grasp and not allowing it to snap back. (Fig. 21)

5. When you hear the engine want to start, return choke

lever to RUN position (open) (B). (Fig. 20)

6. Pull recoil starter briskly again. (Fig. 21)

NOTE If engine does not start, repeat procedures from 2 to 5.

7. Then allow the engine about 2–3 minutes to warm up

before subjecting it to any load.

8. Check that the cutting attachment does not rotate when

the engine is idling. (2) Starting the warm engine Use only 1, 6 and 8 of the starting procedure for a cold engine. If the engine does not start, use the same starting procedure as for a cold engine. Cutting WARNING ○ Always use the harness and wear the proper attire and protective equipment when operating the unit. (Fig. 22) ○ Keep others including children, animals, bystanders and helpers outside the 15 m hazard zone. Stop the engine immediately if you are approached. (Fig. 23) ○ When grass or vines wrap around attachment, stop engine and attachment and remove them. Continuing operation with grass or vines wrapped around the attachment may result in damages such as early abrasion of the clutch. CAUTION Use and points of caution will vary depending on the type of cutting attachment. For safe use, make sure to follow the instructions and guidelines provided with each type. NOTE ○ Press the quick release button or pull emergency release fl ap (If so equipped) in the event of emergency. (Fig. 24) ○ Use in accordance with local laws and regulations. (1) Using a semi-auto cutting head ○ Set the engine at high speed when using this attachment. ○ Cut grass from left to right. The cut grass will be discharged away from the body, minimizing transfer to your clothes. (Fig. 25) ○ With nylon cord, use about 2 cm of the end of the cord to cut grass. Using the full length of the cord will reduce rotation speed and make cutting diffi cult. NOTE Automatically feeds more nylon cutting line when it is tapped at low rpm (not greater than 6000 min

WARNING ○ This product is equipped with a line limiter that will automatically cut any excess cord. When operating the unit, do not remove the guard or line limiter. As the resistance is greater for nylon cords as opposed to blades, mishandling could increase engine load and result in damage. ○ Do not use with the engine set at low speeds. If the engine speed is low, grass may wrap around the attachment, causing the clutch to slip which could result in clutch abrasion. ○ With nylon cord cutters, always use over 15 cm of cord. If the length of the cord is too short, rotation speed will increase and may cause damage to the nylon cord cutter. (2) Using a blade ○ Adjust engine speed according to the resistance of the grass. For soft grass, use low speeds, For tough clumps of grass, use high speeds. ○ Cut grass from right to left, using the left side of the blade to cut. (Fig. 26) ○ Slightly tilting the blade to the left while cutting will pile the cut grass to the left, making collection easy. NOTE Excessively increasing rotation speed may cause increased blade wear, vibration and noise. It will also result in increased fuel consumption. WARNING ○ 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. ○ If cutting attachment should strike against stones or other debris, stop the engine and make sure that the attachment and related parts are undamaged. Stopping (Fig. 27) Decrease engine speed and run at an idle for a few minutes, then turn off ignition switch (26). WARNING A cutting attachment can injure while it continues to spin after the engine is stopped or throttle trigger is released. When the unit is turned off , make sure the cutting attachment has stopped before the unit is set down. 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) The carburetor is a precision part that mixes air and fuel, and it is designed to ensure high performance from the engine. Before the tool is shipped from the factory, its carburetor is adjusted during a test run. Only make adjustments if it is necessary because of environmental conditions (the climate or atmospheric pressure), the type of fuel, the type of engine oil, etc. WARNING ○ Because the carburetor is manufactured with a high degree of precision, do not disassemble it. ○ For this product, the only setting of the carburetor that can be adjusted is the idle speed (T). ○ Never start the engine without the complete clutch cover and tube assembled! Otherwise the clutch can come loose and cause personal injuries. T = Idle speed adjustment screw. Idle speed adjustment (T) WARNING ○ When the engine is stopped, do not excessively turn the idle speed adjustment screw (T) in a clockwise direction. Otherwise, when the engine starts, the cutting attachment may unexpectedly rotate and cause an injury. ○ Do not adjust the idle speed adjustment screw (T) for any reason other than to adjust the idling. Run the engine while adjusting the idling. (1) If the engine stops during idling Start the engine, and slowly turn the idle speed adjustment screw (T) in a clockwise direction until it is in a position at which the engine rotates smoothly. At that time, ensure that the cutting attachment is not spinning. 0000BookCG25EUAP.indb120000BookCG25EUAP.indb12 2019/01/2417:12:592019/01/2417:12:59English

(2) If the cutting attachment rotates during idling Slowly turn the idle speed adjustment screw (T) in a counter-clockwise direction until it is in a position at which the cutting attachment does not rotate. At that time, ensure that the rotation of the engine is smooth. WARNING If the cutting attachment still rotates after adjustment of the idle speed adjustment screw (T), immediately stop the engine and cease use, then contact the nearest HiKOKI Authorized Service Center. Changing the engine oil Dirty engine oil will considerably reduce the service life of the engine. Check and change the engine oil regularly. CAUTION ○ To avoid the risk of burn injuries, allow the engine to cool thoroughly before changing the engine oil. ○ To prevent breakdown, ensure that no sand or dirt gets into the tank while refueling. When to change the oil: When fi rst using the unit, after approximately 10 hours of operation or after 1 month, whichever occurs earlier; subsequently, after every 50 hours of operation or every 6 months, whichever occurs earlier. Specifi ed engine oil: Multigrade oil of classifi cation SAE 10W-

Engine oil capacity: 80 ml

1. Turn off the ignition switch.

2. Check that the fuel cap is securely tightened.

3. Remove the oil cap, tilt the unit so that the oil tank

opening is on the underside and drain the engine oil into a container. (Fig. 29)

4. When all the engine oil has been drained, place the unit

horizontally on a clean, fl at surface.

5. Fill the oil tank with engine oil up to the mouth of the oil

tank opening. (Fig. 17)

6. Tighten the oil cap securely by hand.

NOTE ○ Do not dispose of waste engine oil with garbage or into the ground. Dispose of the oil according to the specifi ed method in your area. If you are unsure, contact the retailer where the oil was purchased. ○ Fill the oil tank with the specifi ed amount of engine oil. Too much or too little engine oil may result in engine breakdown. ○ Engine oil deteriorates naturally even if unused. Change the engine oil regularly. Air fi lter (Fig. 30) The air fi lter (30) 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 fi lter daily or more often if working in exceptionally dusty areas. Cleaning the air fi lter Remove the air fi lter cover and the fi lter (28). Rinse it in gasoline. Check that the fi lter is dry before reassembly. An air fi lter that has been used for some time cannot be cleaned completely. Therefore, it must regularly be replaced with a new one. A damaged fi lter must always be replaced. Fuel fi lter (Fig. 31) Remove the fuel fi lter (31) from the fuel tank, and replace it if it is dirty. NOTE A blocked fuel fi lter (31) can prevent the supply of fuel and cause a rotation malfunction of the engine. Spark plug (Fig. 32) The spark plug condition is infl uenced by: ○ An incorrect carburetor setting. ○ A dirty air fi lter. ○ Hard running conditions (such as cold weather). ○ Too much engine oil 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 fi rst. 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. Gear case (Fig. 33) Check gear case or angle gear for grease level about every 50 hours of operation by removing the grease fi ller plug on the side of gear case. If no grease can be seen on the fl anks of the gears, fi ll the gear case with quality lithium based multipurpose grease up to 3/4. Do not completely fi ll the gear case. CAUTION ○ Make sure to remove any dirt or grit when attaching the plug to its original position. ○ Before attempting inspection or maintenance of the gear case, make sure the case has cooled.
