water and allow element to air dry.
NOTE
If element is hard due to excessive dirt buildup,
replace it.

Spark plug (Fig. 34)
The spark plug condition is influenced by:
O An incorrect carburetor setting
OWrong fuel mixture (too much oil inthe gasoline)
O A dirty air filter
OHard 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 0.024" (0.6 mm).
The spark plug should be replaced after about 100
operation hours or earlier if the electrodes are badly
eroded.
0.024-
(0.6 rnrn) _

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.
Flexible drive shaft (Fig. 35)
Flexible drive shaft should be removed and
lubricated with good quality lithium grease every
20 hours. To remove the flexible shaft, first remove
screw (29), loosen bolt (30) and remove the gear
case then pull the shaft out of the drive shaft pipe.
Clean the shaft off and apply a generous coat of
lithium grease to it and insert if back into the drive
shaft pipe, turn it unit it drops into place then install
the gear case, install & tighten screw (29) and screw
(30).

Check angle transmission or angle gear for
grease level about every 50 hours of operation by
removing the grease filler plug on the side of angle
transmission.
If no grease can be seen on the flanks of the gears,
fill the transmission with quality lithium based
multipurpose grease up to 3/4. Do not completely fill
the transmission.

© Use a sharp blade. A dull blade is more likely to
snag and thrust. Replace the fastening nut if it is
damaged and hard to tighten.
© When replacing blade, purchase one
recommended by Hitachi, with a 25.4 mm (one
inch) fitting hole.
© When installing a saw blade (38), always face
the stamped side up. In the case of a 3 or 4 tooth
blade (37), it can be used on either side.
© Use the correct blade for the type of work.
© When replacing blades, use appropriate tools.
© When cutting edges become dull, re-sharpen
or file as shown in the illustration. Incorrect
sharpening may cause excessive vibration.
