INSTALLATION
Since the installation method affects the service life, easy
of
maintenance, frequency
of
check and repair, and operating cost
of
engine,
the following contents
shall
be carefully examined before installing
your
engine.
5-1
MOUNTING
When installing the engine, its mounting position, coupling condition with operating machines, and anchoring or supporting
m&o& must be carefully examined. Particularly when determining its mounting position, due care should be taken
to
assure the convenience
of
such routines as replenishment and checking
of
fuel and oil, checking
of
oil
gauge, spark-plug and
contact breaker point, maintenance
of
oil draining. For details, refer
to
the installation drawing.
Install the engine as much closer as possible to the level. The tilt limit for normal operation should be not more than
30°
from the level.
5-2
VENT1 LATION
The fresh air must be supplied
to
the engine
for
cooling and fuel combustion.
If
the engine
is
operated with a cover or in a
small compartment,' it is required
to
provide a cooling air duct and a baffle plate.for the purpose
of
preventing insufficient
circulation
of
heated air after cooling the engine and/or temperature rise
of
related equipment. High temperature
environment will cause engine vapor-lock, deterioration
of
oil, power reduction,
loss
of
engine life, it is requested to keep
the temperature
of
compartment not to exceed
50°C.
5-3
EXHAUST GAS EVACUATION
As
the exhaust gas is toxic, it must be exhausted outside in case engine is operated indoor.
Output power of 2-cycle engine is considerably influenced by the length
of
exhaust duct,
so
ask for consultation in case any
modification
of
exhaust system is required.
54
FUEL SYSTEM
In case the standard fuel tank can not be used due to space limitation or any other reason, take the following notes into
consideration:-
1) When connecting the fuel pipe, carefully examine heat conductivity, pipe diameter, bend and leakage from fittings to
eliminate air-blocking and vapor-lock.
2)
Men
the
fuel
is
to
be fed by gravity, position of fuel tank bottom should fie
within
the
height
of
5
-
50
cm from
the
fuel
joint
of
the
carburetor.
3)
Fuel must be filtered before it
is
fed to carburetor, by means
of
fuel strainer or filter.
4)
The standard inner diameter
of
fuel pipe is
4
-
5
mm.
.
5)
It is recommended to minimize the length
of
fuel pipe.

Be careful with the following items.
Use a V-belt rather thana flat-belt.
Set the driving shaft and the driven shaft of machine in parallel for each other.
Align the driving pulleys
of
engine and machine correctly.
