OPERATING PROCEDURES

Fuel (Fig . 1)

WARNIN G

The hedge trimmer is equipped with a two- stroke engine.

Always run the engine on fuel, mi xed with oil.

Provide good ventilation, when fueling or handling fuel.

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 GR ADE OIL or ISO EGC GRADE). Do not use BIA or TCW

(2-stroke water-cooling type) mixed oil. Never use mult i-grade oil (10W/30) or waste oil. Always mix fuel and oil in a separate clean container.

Always start by ﬁ lling 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 ﬁ lling the fuel tank.

Fueling

WARNIN G (Fig. 2)

Always shut o the engine before refueling. Slowly open the fuel tank (1), when ﬁ lling up with fuel, so that

possible over-pressure disappears. Tighten the fuel cap carefully, after fueling. Always move the unit at lea st 3 m from the fueling area before

starting.

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 cont ainer, before fueling.

NOTE

If engine does not start, repeat procedures from 2 to 4.

5. After starting engine, allow the engine about 2-3 minutes to warm up before subjecting it to any load.

Cutting

When cutting, operate engine at full throttle as this maintains proper blade speed. When trimming top of hedge, hold trimmer so blades are between 15 and 30 degrees from a horizontal position and swing t rimmer in an arc toward edge of hedge to sweep cut tings o . When trimming sides of hedge, hold blade vertically and swing unit in an arc.

NOTE

Multi-position twist handle (Fig. 7)

The rear control handle turns 90 degrees to prov ide

comfortable use while accommodating a variety of cutting angles. The handle allows for ﬁ ve di erent locking positions. Before attempting to adjust rear handle, make sur e the machine is at idle or engine is shut o .

MAINTENANCE

MAINTENANCE, REPLACEMENT OR REPAIR OF THE EMISSION CONTROL DEVICES AND SYSTEM MAY BE PERFORMED BY ANY NONROAD ENGINE REPAIR ESTABLISHMENT OR INDIVIDUAL.

Carbu retor adjus tment (Fig . 9)

WARNING

The cutting at tachment may be spinning during carburetor

adjustments.

Never start the engine without t he complete cleaner cover.

Other wise 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 adjusted. A fu rther adjustment may be required, according to climate and altitude. The carburetor has one adjustment possibility:

T = Idle s peed adjus tment scr ew.

Idle s peed adjus tment (T )

Check that the air ﬁ lter 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 reac hed the correct idle speed when the engine run s 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 Hitach i dealer.

Air ﬁ l ter (Fig. 10)

The air ﬁ lter 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.

Clea ning the air ﬁ lter

Remove the cleaner cover and the ﬁ lter. Rinse it in warm soap suds. 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 by a new one. A damaged ﬁ lter must always be replaced.

NOTE

Saturate the element in 2-cycle oil or the equivalent. Squeeze

the element to distribute the oil completely and to remove any excess oil.

Spar k plug (Fig. 11)

The spark plug condition is inﬂ uen ced by:

An incorrect carburetor setting.

Wrong fuel mix ture (too much oil in the gasoline).

A dirty air ﬁ lter.

Hard running conditions (such as cold weather). These factors cause deposits on the spark plug electrodes, which may result in malfunction and starting di culties. If the engin e is low on power, di 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. Readju st i f 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 pl ug, use the same type of spark plug for replacem ent.

Lubr icating th e bla de (Fig.12)

During trimming, sap adhering to the blade edge will increase load. Use machine oil (or bicycle oil or the like) to lubricate the blade and wipe the blade with a cloth. To prevent the blade from r usting, be sure to lubricate the blade after use and when it will not be used for an exten ded period of time before placing it in the blade case.

Gear c ase (Fig. 13)

Apply a good quality lithium based grease through the grease ﬁ tting until a small amount comes out between the cut ting blades and the gear case. Lubricate the grease from the grease nipple (indicated by an arrow) next to the gear case using a commercially available cartridge grease gun.

NOTE

Lubrication should be applied 3g at 20 hour intervals and more

frequently with heavy use.

Fuel ﬁ lter (Fig. 14)

Remove the fuel ﬁ lter from the fuel tank and t horoughly wash it in solvent. After that, push the ﬁ lter into the tank completely.

NOTE

If the ﬁ lter is hard due to du st and dirt, replace it.

Clea ning the cyli nder ﬁ ns (Fi g. 15)

When leaves get caught between cylinder ﬁ ns (7), the engine may overheat, resulting in lower output. To avoid this, always keep cylinder ﬁ ns and cylinder cover clean. Every 100 operating hours, or once a year (more often if conditions require), clean ﬁ ns and external surfaces of engine of dust, dirt and oil deposits which can contribute to improper cooling.

Clea ning the mu er (Fig . 16)

Remove the mu er and spark arrestor (if so equipped), and clean out any excess ca rbon from the exhaust port or mu er inlet every 100 hours of operation.

For lon g-term s torage

Drain all fuel from the fuel tank . Start and let engine run until it stops. Repair any damage which has resulted from use. Clean the unit with a clean rag, or high pressure air hose. Put a few drops of two-cycle engine oil into the cylinder through the spark plug hole, and spin the engine over several times to distribute oil. Cover the unit and store it in a dry area.

Main tenance sch edule

Below you will ﬁ nd some general maintenance instructions. For further inform ation please contact your Hitachi dealer.

Daily maintenan ce
