OPERATING PROCEDURES
Fuel (Fig . 13)
Fig. 13
WARNING
The unit /machi ne is equipped with a t wo-st roke engin e. Always
run the e ngine on fuel, whic h is mixed wi th oil. Provide good ventilatio n, when fueling or ha ndling fuel. Fuel contains highly fl ammable and it is possible t o get the
serious personal injury when inhaling or spilling on your body.
Always pay attenti on when ha ndling fuel. Always h ave good
ventil ation when handli ng fuel inside buil ding.
Fuel
Always u se branded 89 octa ne unlead ed gasol ine. Use gen uine two -cycle oil or use a mi x betwee n 25:1 to 50:1,
pleas e consult the oil bot tle for th e ratio or HiKOKI Autho rized
Service Centers. If genuine oil is not av ailable, use an anti -oxida nt added quality
oil expr essly la beled for a ir-cool ed 2-cycle engine u se (JASO
FC GRADE O IL or ISO EGC GR ADE). Do not u se BIA or TCW
(2-stro ke water-cooling type) mi xed oil.
Never us e for four-st roke engi ne oil or was te oil. Always m ix fuel and oil in a sepa rate clea n contai ner.
Always st art by fi ling hal f the amou nt of fuel, which is to be u sed. Then add the whole a mount of oi l. Mix (shake) the fuel mix ture. Add the remaining am ount of fuel. Mix (shake) th e fuel-m ix thorou ghly before fi l ling the fuel tank.
Fueling
WARNING
Always shut o the engine an d let it coo l for a few minu tes
before refueling. Slow ly open th e fuel tank, when fi lling up with fuel, so that
possible over-pressure disappears.
Tight en the fuel cap caref ully, after fueling. Always move the unit at leas t 3 m from the fueling ar ea before
starting. Do not smoke and/or allow fl ames or sparks near fuel when
handling or fi lling fuel. Always wash any spilled fuel from clothing immediately with
soap. Be sure to check for a ny fuel lea kage after ref ueling.
Before fueling, clean the tank cap area carefully, to ensure that no dirt falls into t he tank. M ake sure that the fuel i s well mixed by shaki ng the container, before fueli ng.

(2) Star ting the warm en gine Use onl y 1, 2 and 6 of the sta rting p rocedu re for a cold e ngine. If the engine does not star t, use the s ame star ting procedure a s
for a cold e ngine.
Operating blower (Fig. 18)
A low spe ed should be used to bl ow leaves an d dry gra ss. A mediu m speed sh ould be used to clean wet leaves and grass. A high speed should be used when moving gravel, dirt or other
heavy materials.
When working in a dusty are a, hose dow n the area with water.
Fig. 18
WARNING
Do not direct discharge of a ir toward people or pet. The uni t should be oper ated in a well ventilated area. Neve r perfor m assembly or disa ssembl y proced ures with
engin e running or serious personal injur y may result.
Never touc h mu er, spark plug, or other metallic parts while
engin e is in running or imme diately after shutti ng off engine.
Do not us e this blower indoor s. Do not o perate if t here is an open window near the wo rk area
and its s urroundings.
CAUTION
This blower has been designed and adjusted to be used with
blowin g pipes at tached. It must never be opera ted witho ut the straight pipe.
NOTE
Blowing Pipe Sel ection
• Straight Bl owing Pip e Allows operat ion at maximu m blow capa city. Suitable for operation in widespread areas, engine revolution
is kept at a minimum, resulting in improved fuel consumption when co mpared wi th the con ic/fan -shaped blow ing pipe.
The straight blowing pipe is recommende d for normal use.
• Conic/Fan -Shape d Blowing P ipe Allows operat ion at maximu m blow spee d. Idea l for blowing wet leaves s tuck to the g round or re leasing a
power ful air discharge i n limited spaces.
Operating vac uum (Fig. 19)
WARNING
Do not vacuum bot tles , cans or any o ther hard materi als,
which m ay cause da mage or serious in juries .
Do not use a bag with hol es or tears in it. Even a sm all hole
can cau se a lot of dus t to come out . Repair or replace i t immediately.
Make sur e zipper of t he bag is com pletely c losed.
8
Wear shoulder strap over right or left shoulder. Make sur e bevel at end o f suctio n pipe face s downward. The uni t should be oper ated In a well ventilated area. Use rake s and broom s to loosen debris before vacuuming. A low speed should b e used to vac uum small leaves and d ry
grass.
A medium speed should be used to vacuum large leaves and
grass.
A high speed should be used to vacuum larger or wet leaves
and grass.
Dispose of debr is in the bag more freq uently in d usty condit ion.
NOTE
When you hear or feel strange sound or vibration, stop engine
immediately an d check if a nythin g blocks fans or pipes, If so, remove it and check for damage.

Idle sp eed adju stment (T)
Check t hat the air fi lter is clean. If adjustment is required, turn IDLE spe ed Adjust ment Scr ew (T) clo se (clock wise) to inc rease engine speed, open (counterclockwise) to decrease engine speed. Stand ard Idle rpm is 2800 -3200 rpm.
CAUTION
The above adju sting procedure m ust be followed when
adjustment is MADE or DAMAGE to engine will occur because of the incorrec t condition.
NOTE
Some models sold areas with strict exhaust emission
regulation do no t have high an d low speed carburetor adjustments. S uch adjustments m ay allow th e engine to b e operated outsi de of their emission compli ance lim its. For th ese model s, the only carbure tor adjus tment is idle speed .
Fig. 21
RECOMMENDATION
CARBURE TOR ADJUSTMENT NEEDS THE S KILL OF EXPERIENCED OR WELL TRAINED PEOPLE, OR IS RECOMMENDED TO TAKE THE UNIT TO HiKOKI AUTHORIZED SERVICE CENTERS.
Air fi lter (Fig . 22)
The air fi lter mus t be clean ed from dus t and dir t in order to avoid:
Carburetor malfunctions Starting problems Engine power reduction Unnec essary wear o n the engi ne parts Abnor mal fuel consumption
Clean the air fi lter daily or more o ften if working in exc eption ally dusty areas.

MAINTENANCE
MAINTENANCE, REPLACEMENT OR REPAIR OF THE EMISSION CONTRO L DEVICES AND SYSTEM S MAY BE PERFORM ED BY ANY NON- ROAD ENGINE REPAIR ESTABLI SHMENT OR INDIV IDUAL.
Carbur etor adju stment (F ig. 21)
The car buretor i s a precis ion part that mixes air and fue l, and it is desig ned to ensu re high pe rformance from t he engin e. Before th e tool is shipped from the factory, its carburetor is adjusted during a test run . Only make adjustme nts if it is n ecessa ry beca use of environmental conditions (the climate or atmospheric pressure), the type of fuel, the t ype of two-c ycle oil, etc.
WARNING
Because the c arburetor is manu facture d with a hig h degree of
preci sion, do no t disass emble it .
For th is produ ct, the on ly setti ng of the ca rbureto r that can be
adjusted is the id le speed ( T).
T = Idle sp eed adjustmen t screw.

Clean ing the ai r fi lter
Open th e air fi lter cover and remove the ai r fi lter. Clean i t. Check that the fi lter is dry b efore rea ssembl y. An air fi lter that has been used for s ome time c annot be cleaned completely. Therefor e, it must regularly be replac ed with a new o ne. A damag ed fi lter must always be replaced.
Fuel fi lter (Fig. 23)
Remove the fuel fi l ter from th e fuel tan k, and rep lace it if it is dirt y.
NOTE
A blocked fuel fi lter can preve nt the supply of fuel a nd cause a
rotati on malfu nction o f the engine.

Spark p lug (Fig. 24)
When removing th e spark plug, twis t and remove t he plug ca p coveri ng the spark plug as shown in the illustra tion. (Fig. 25) The spark plug condition i s infl uenced by:
An incorrect carburetor setti ng Wrong fu el mixt ure (too muc h oil in the g asolin e) A dirt y air lter Hard ru nning co ndition s (such as c old weather)
These factors cause deposits on the spark plug electrodes, which may resu lt in malfunction and star ting diffi culties. If the engine is low on power, diffi cult to start or runs poorly at idling speed, always ch eck the sp ark plug fi rst. If the spa rk plug is d irty, cle an it and che ck the ele ctrode g ap. Re-adjust if necessar y. The corre ct gap is 0.6 m m. The spar k plug sho uld be replaced af ter about 100 operation hour s or earlier if the electrodes are b adly erod ed.

Fig. 24
NOTE
In some are as, loca l law requires using a r esistor spark plu g
to suppr ess igni tion sig nals. If this machi ne was ori ginally equipped with resistor spark plug, use same type of spark plug for replacement.
For long-term s torage
Drain a ll fuel fro m the fuel t ank. Sta rt and le t engine r un until it stops. R epair any d amage whi ch has res ulted fro m use. Clea n the unit with a clean rag, or the use of high pre ssure air hose. Put a few drops of t wo-cycle engi ne oil into t he cylinder throu gh the spark plug ho le, and spin the engine over sever al times to d istrib ute oil. Cover the unit and st ore it in a dr y area.
