Fig. 12 Fig. 13

NOTE

Use in accordance with local laws and regulations.

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. 14)
○ Cut grass from right to left as the cutting attachment of the curved drive shaft tube model rotates clockwise.
With nylon cord, use about 3/4" (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.

Diagram illustrating a mechanical device and worker cleaning a surface with directional arrows indicating motion or movement.

Fig. 14

NOTE

Automatically feeds more nylon cutting line when it is tapped at low rpm (not greater than 4,500 min ^-1 ).

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 5-7/8" (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. As the curved drive shaft tube model in particular is not equipped with a deceleration mechanism, the possibility of increased rotation speed for the cutting attachment is high.

Stopping (Fig. 15)

Decrease engine speed and run at an idle for a few minutes, then turn off ignition switch (8).

Fig. 15

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.

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. 16)

Line drawing of a mechanical device with a tool inserted, showing internal components and no text or symbols.

Fig. 16

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 two-cycle 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.
(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 Hitachi Authorized Service Center.

Air fi Iter (Fig. 17)

The air filter (12) 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 Iter daily or more often if working in exceptionally dusty areas.

Fig. 17

Cleaning the air fi Iter

Open the air filter cover and remove the air filter (12). Rinse it in warm soap suds. Check that the filter is dry before reassembly. An air fi liter that has been used for some time cannot be cleaned completely. Therefore, it must regularly be replaced with a new one. A damaged fi liter must always be replaced.

Fuel fi Iter (Fig. 18)

Remove the fuel fi Iter (13) from the fuel tank, and replace it if it is dirty.

NOTE

A blocked fuel fi Iter (13) can prevent the supply of fuel and cause a rotation malfunction of the engine.

Technical line drawing of a mechanical device with labeled component (13), no readable text or symbols beyond the number and label

Fig. 18

Spark plug (Fig. 19)

The spark plug condition is influenced by:

○ An incorrect carburetor setting
○ Wrong fuel mixture (too much oil in the gasoline)
○ A dirty air fi Iter
○ 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 fi rst. If the spark plug is dirty, clean it and check the electrode gap. Re-adjust if necessary. The correct gap is 0.024" (0.6 mm). The spark plug should be replaced after about 100 operation hours or earlier if the electrodes are badly eroded.

0.024" (0.6 mm)

Fig. 19

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. 20)

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 flanks 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.

WARNING:

Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• Lead from lead-based paints,
• Crystalline silica from bricks and cement and other masonry products, and
• Arsenic and chromium from chemically-treated lumber.

Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.
