Checking and adjusting t h e idling s p e e d
The
cutting
blade should
not
when the control lever
is
fully released.
-
Idle
speed should be s e t to
2,600
rpm.
If necessary, correct it by means
of
the idle screw (the cutting
blade must not run when the engine i s on idle).
Clockwise
:
for
faster rate of revolution
Counter-clockwise
: for
slower rate of revolution Check that
there
is
sufficient difference between idling and clutch
engagement speed to ensure that the cutting tool i s at
a
standstill while the engine
i s
idling.
(If
necessary, reduce idling
speed.) If the tool still continues to
run
under the idling
conditions, consult your nearest authorized service agent.
The clutch should engage at minimum
3,250
rpm.
Check the functioning of the
STOP
switch, the lock-off lever, the
control lever, and the
lock
button.
Cleaning of air cleaner
-
Every 8 hours (Daily)
-
Remove the air cleaner cover.
-
Push the choke lever up (arrow), to prevent dirt particles from
entering the carburetor.
-
Take out the sponge element, wash it in lukewarm water and dry it
completely.
-
After cleaning, put back the sponge element and the
air
cleaner
cover.
NOTE
If
there is excessive dust or dirt adhering to the air cleaner,
clean it every day.
A
clogged
air
cleaner may make it
difficult or impossible to start the engine or increase the
engine rotation speed which could c a u s e damage.
.
Checking the spark plug
-
Every 8 hours (Daily)
-
Only u s e the supplied universal wrench to remove or to install the
spark plug.
-
The g a p between the two electrodes
of
the spark plug should be
0.6
to 0.7mm.
If
the g a p
is
too wide or too narrow, adjust it.
If
the spark plug is clogged with carbon or fouled, clean it thoroughly
or replace it. Use a n exact replacement.
Supply of g r e a s e and lubricant
-
Supply grease from the grease nipple every
15
operating hours.
(Shell Alvania
No.3
or equivalent)
The amount
of
grease
for
each supply
is
about 20cc.
(Once grease
i s
supplied regularly as mentioned above, grease will
come out from the end of the gear case (root of the cutting edge) in
operation just after supply of grease. Confirm this phenomenon as
a
guide to grease supply.)
NOTE:
Be sure to observe the specified time and amount of grease
supply.
If
the grease supply i s not made at the specified interval or
if
the amount of grease supplied i s not sufficient, the machine
may fall into
a
trouble because
of lack of
grease.
