OPERATING PROCEDURES

Fuel (Fig . 1)

WARNIN G

The hedge tri mmer is equipped wi th a two- stroke engine.

Always run the engin e on fuel, mixed 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 be tween 25:1 to 50:1,

please consult the oil bot tle for the ratio or Hitachi dealer.

If genuine oil is not available, use an anti -oxidant added qua lity

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 se parate cl ean containe r.

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 rema ining amount of fuel. Mix (shake) the fuel-mix thoroughly before ﬁ l ling the fuel ta nk.

Fueling

WARNIN G (Fig. 2)

Always shut o the engine before refue ling. Slowly open the fuel ta nk (1), wh en ﬁ lling up with fuel, so that

possi ble over-pressure disappears. Ti ghten the fuel ca p carefully, after fueling . Always move the unit at lea st 3 m from the fueling area before

starting.

Before fu eling, clean t he tank cap area ca refully, to ensur e that no dirt falls into the tank. Make sure th at the fuel is wel l mixed by shaking the cont ainer, before fueling.

English

Lubri cating th e blade (Fig.12)

During trimming, sap adhering to the blade edge will increase load. Use machine o il (or bicycl e oil or the like) to lubricate the blade and wipe the blade with a cloth. To prevent the blade from rusting, 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 base d greas e throu gh the grease ﬁ t ting until a small amount co mes out between the cutting blades and the gear case. Lubricate the grease from th e grease nipple (indicated by an arrow) next to the gear case using a commercia lly available cartridge grease gun.

NOTE

Lubricatio n should be applied 3g at 20 hour interval s and more

freque ntly with heav y use.

Fuel ﬁ lter (Fig. 14)

Remove the fuel ﬁ lter from the fu el tank and thoroughly wash it i n solvent. After that, push the ﬁ l ter into th e tank co mpletely.

NOTE

If the ﬁ lter is hard due to dust and dirt, repl ace it.

Clea ning the cyli nder ﬁ n s (Fig. 15)

When leaves get ca ught bet ween cylinder ﬁ ns (7), the engine may overhea t, resulting in lower output. To avoid th is, 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 an d external surfaces of eng ine of dust, dirt and oil depo sits which ca n 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 operati on.

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 clea n rag, or high pressure air hose. Put a few drops of two-cycle engine oil into the cylinder through the spark plug h ole, and spin t he engine over several times to distribute oil. Cover the unit and store it in a dry area.

Mainte nance sch edule

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

Daily maintenanc e

Cl ean the exterior of the hedge trimmer. Ch eck the blade guide for damage or cr acks. Change the guard

in case of impacts or cracks.

Ch eck that the blade is sharp, and without cracks. Ch eck that the blade nut is su ciently tightened. Make sure that the blade blu nt guard is undamaged and that it

can be securely ﬁ tted.

Ch eck that nuts and screws are su ciently tightened.

Weekl y maintena nce

Ch eck the starter, especia lly cord and retu rn spring. Cl ean the exterior of the spar k plug. Rem ove it and check the electrode gap. Adjust it to 0.6 mm, or

change the spark plug.

Cl ean t he cooling ﬁ ns on the cylinder and check that the air

intake at the starter is not clo gged.

Ch eck gear case is ﬁ lled with gre ase. Cl ean the air ﬁ lter.

Mont hly mainte nance

Rinse the fuel tank with gasoline. Cl ean the exterior of the car buretor and the space around it. Cl ean the fan and the space arou nd it.

MAINTENANCE

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

Carbu retor adjus tment (Fig . 9)

WARNING

Th e cutting attachment may be spinning during car buretor

adjustments.

Never start the eng ine without the complete cleaner cover.

Other wise t he clutch can come loose and cause personal

injuries. In the carburetor, fu el is mixed with air. When the engine is tes t run at the factory, th e carburetor is adjusted. A further adjustment may be required, according to climate and altitude. The ca rburetor 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. Wh en the idle speed is corr ect, the cutting attachment will not r otate. If adjustment is required, close (clock wise) the T-screw, with the engine running, until the cutting attachment starts to rotate. Open (cou nter-clock wise) the screw until th e cutting attachment stops. You have reached the co rrect 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 adjustme nt, contac t Hitachi dealer.

Air ﬁ lter (Fig . 10)

The air ﬁ lter must be cleaned from dust and dir t in order to avoid:

Car buretor malfunction s. Starting problems. En gine power reduction. Unn ecessary wear on the engine par ts.

Abnormal fuel consu mption. Clean the air ﬁ lter daily or more often if working in exceptionally dusty areas.

Clea ning the air ﬁ lt er

Remove th e cleaner cover and the ﬁ lter. Rinse it in warm soa p 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 rep laced by a new one. A damaged ﬁ lter must always be replaced.

NOTE

Saturate the ele ment in 2-cycle oil or the e quivalent. Squeeze

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

Spar k plug (Fig. 11)

The spark plug con dition is inﬂ uenced by:

An incorrec t carburetor s etting.

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

A dirty air ﬁ lter.

Ha rd running conditions (such as cold weather). These factors cause deposits on the spark plug electrodes, which may result in mal function and star ting di culties. If t he engine is low on power, di cult to start or runs poorly at idling speed, always check the spark plug ﬁ r st. If the spark pl ug is dirty, clean it and check the electrode gap. Readju st i f nece ssary. The correct gap is 0.6 mm. Th e spark plug should be replaced after about 100 operation hours or earlie r i f the electrodes are badly erode d.

NOTE

In some areas, local law requires using a resistor spark plug

to suppress ignition sign als. If this machine was originally equipped with resistor spark plug, use the same type of spar k plug for replacem ent.
