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. 13)

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).

T = Idle speed adjustment screw.

Idle speed adjustment (T)

Check that the air ﬁ lter is clean. If adjustment is required,

turn IDLE speed Adjustment Screw (T) close (clockwise)

to increase engine speed, open (counterclockwise) to

decrease engine speed. Standard Idle rpm is 2800-

3200 rpm.

CAUTION

The above adjusting procedure must be followed when

adjustment is MADE or DAMAGE to engine will occur

because of the incorrect condition.

NOTE

Some models sold areas with strict exhaust emission

regulation do not have high and low speed carburetor

adjustments. Such adjustments may allow the engine to

be operated outside of their emission compliance limits.

For these models, the only carburetor adjustment is idle

speed.

RECOMMENDATION

CARBURETOR ADJUSTMENT NEEDS THE SKILL

OF EXPERIENCED OR WELL TRAINED PEOPLE, OR

IS RECOMMENDED TO TAKE THE UNIT TO HiKOKI

Authorized Service Centers.

Air ﬁ lter (Fig. 14)

The air ﬁ lter (11) 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.

Cleaning the air ﬁ lter (Fig. 14)

Open the air ﬁ lter cover (12) and remove the air ﬁ lter (11).

Clean it.

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

with a new one. A damaged ﬁ lter must always be replaced.

Fuel ﬁ lter (Fig. 15)

Remove the fuel ﬁ lter (13) from the fuel tank, and replace it

if it is dirty.

NOTE

A blocked fuel ﬁ lter (13) can prevent the supply of fuel

and cause a rotation malfunction of the engine.

Spark plug (Fig. 16)

When removing the spark plug, twist and remove the plug

cap covering the spark plug as shown in the illustration.

(Fig. 17)

The spark plug condition is inﬂ uenced by:

○ An incorrect carburetor setting.

○ Wrong fuel mixture (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 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 0.6 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 plug, use same

type of spark plug for replacement.

For long-term storage

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 the use of 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.
