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 is highly flammable and toxic and can result in serious injury if it is inhaled or comes into contact with your skin. Always handle fuel with care. 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.

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 brush cutter at least 3m from the fueling area before starting.
Always wash any spilled fuel from clothing in soap.
Be sure to check for any fuel leakage after refueling.

Before fueling, clean the tank cap area carefully, no dirt falls into the tank. Make sure that the fuel is well mixed by shaking the container, before fueling.

• 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 (19) of the harness to the direction of the arrow shown in Fig. 24-a.

If the cutting attachment should strike 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.

NOTE

If you pull the emergency release pinch without holding the machine, the machine will fall to your feet. Pull the emergency release pinch while 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 (14).

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 11-14 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 your Hitachi dealer.

NOTE

Standard Idle rpm is 2500-3000 rpm.

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

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 (25). 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 fi lter 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. 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 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 0.6mm . The spark plug should be replaced after about 100 operation hours or earlier if the electrodes are badly eroded.

Muffler (Fig. 32)

Remove the muffler and clean out any excess carbon from the exhaust port or muffler inlet every 100 hours of operation.

Cylinder (Engine cooling) (Fig. 33)

The engine is air cooled, and air must circulate freely around engine and over cooling fins on cylinder head to prevent overheating. Every 100 operating hours, or once a year (more often if conditions require), clean fins and external surfaces of engine of dust, dirt and oil deposits which can contribute to improper cooling.

NOTE

Do not operate engine with engine shroud or muffler 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 blade, purchase one recommended by Hitachi, with a 25.4mm (one inch) fitting hole.
When installing a saw blade, always face the stamped side up. In the case of a 3 tooth blade, 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.

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 (Fig. 37), hook the new nylon line into the hole of the spool, then wind it around the spool (Fig. 38).

When the nylon line has been wound around the spool, temporarily fasten it in the opening of the spool at about 10cm from the end. (Fig. 39) 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 15 - 16cm from the end. (Fig. 41)

NOTE

The nylon head is designed for nylon lines with an outer diameter of 2.5mm . 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
