Installation; Mounting; Ventilation; Exhaust Gas Evacuation - Robin EC05-2 Service Manual

- 5 . 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 i s operated with a cover o r 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.
5 4 FUEL SYSTEM
In case the standard fuel tank can not be used d u e t o 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) M e n 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 t o minimize the length of fuel pipe.
5-5 POWER TRANSMISSION to DRIVE MACHINES
5-5-1 BELT-DRIVE
Be careful with the following items.
Use a V-belt rather t h a n a flat-belt.
Set the driving shaft and the driven shaft of machine in parallel for each other.
Align the driving pulleys o f engine and machine correctly.
