燃料过滤器（图 12）
将燃料箱内的燃料排干，然后拉出箱内的燃料过滤
线。将滤芯从支架组件中拉出，并用含洗涤剂的温水
清洗。
进行彻底的清洗直至无洗涤剂残留为止。
将多余的水挤出（请勿扭转），并放置于空气中晾
干。
注
如果滤芯由于聚集过多灰尘而变硬，请进行更
换。
火花塞（图 13）
火花塞的状况受以下条件影响：
○ 不正确的化油器设置。
○ 错误的燃料混合物（ 汽油中含有过多机油）。
○ 空气过滤器脏污。
○ 艰难的运转条件（如天气寒冷）。
造成火花塞电极上聚集污物的几个条件可能会导致故
障和启动困难。如果发动机的动力低、无法启动或怠
速下运转不良，请首先检查火花塞。如果火花塞脏
污，请对其进行清洁并检查电极间距。如需要，可重
新进行调整。正确的间距为 0.6 毫米。火花塞在工

turn offignition switch.
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. 10)
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. 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 2800-3200rpm.
RECOMMENDATION
CARBURETOR ADJUSTMENT NEEDS THE SKILL OF
EXPERIENCED OR WELL TRAINED PEOPLE, OR IS
RECOMMENDED TO TAKE THE UNIT TO HITACHI DEALER.
Air filter (Fig. 11)
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
Remove the air cleaner cover by pushing and pulling back the tab
on the top.
Clean the air filter daily or more often if working in exceptionally
dusty areas.
Cleaning the air filter
Open the air filter cover and the filter. 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. 12)
Drain all fuel from fuel tank and pull fuel filter line from tank. Pull
filter 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. 13)
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 0.6 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.
