BELT DRIVE
Take the following notes into consideration.
*
V-belts are preferable to flat belts.
*
The driving shaft of the engine must be parallel to the driven shaft
of
the machine.
*
The driving pulley of the engine
must
be in line with the driven pulley
of
the
machine.
*
Install the engine pulley as close to the engine
as
possible.
*
If
possible, span the belt horizontally.
*
Disengage the load when
starting
the
engine.
If
no
clutch
is
used, use a belt tension pulley or the like.

FLEXIBLE
COUPUNG
When using
a
flexible coupling, runout and misalignment between the driven shaft and the engine shaft
must be minimized. Runout and misalignment tolerance are specified by
the
coupling manufacturer.

FUEL
SYSTEM
When remote mounting fuel
tank,
set
the fuel head (height difference between fuel
tank
bottom and
carburetor fuel inlet)
to
5
-
50cm
(2
-
20
in).
Not
enough
fuel
head causes a pour fuel supply and the
excessive head induces overflow
of
carburetors.
To
avoid air lock and vapor lock,carefully examine diameter and car rature
of
fuel hose, heat trasfer and
leak at
joints.
Make the hose length
as
short
as
possible. Fuel filter must be installed in the fuel system.
