below 10 meters, this fuel inlet pipe's inside diameter
shall be at least 20% bigger than that of the hose
installed in this engine. Fuel return pipe shall be
connected to the top of fuel tank. Don't directly
connect it to fuel inlet pipe.

Fuel consumption
The content of diesel plays a very critical role in diesel
engine's performance, life expectancy and the
content of discharged material. In order to achieve
the rated power, fuel economy and specified
emission standard, only the fuel which refer to
international standard or national standard can be
used.
The parameters of diesel fuel include low
temperature feature, sulphur content, specific gravity,
water content and foreign material content shall be
the first priority when user need to choose the quality
of the fuel. Different quality of fuel will directly affect
diesel generator set's start, lubricating, output power,
discharge, and fuel filter change cycle etc.
Specific requirement for fuel please refer to engine
operation manual which attached with the generator
set.
Warning:
! When you intend to add fuel into the fuel tank,
please make sure the generator set has been stopped.
Only after the added fuel become static for some
time, this generator set can be started again. This
way to avoid the foreign material in the diesel fuel
being sucked to fuel supply hose, which will cause
fuel filter stuck and fail to supply engine with
sufficient fuel, and in turn decrease the output
power.
! The malfunction caused by bad quality of fuel does
not belong to the scope of warranty.
2.8
Control system
Our diesel generator sets has been furnished with
control panel. All of the control panels choose
imported digital meter as the core of control system
for the generator sets.
◆ Digital control panel: the generator set can be
controlled locally by manual, and also can be started
or stopped by remote control (controlled by external
signal line) users are required to correctly connect the
signal line to this control panel.(details see the
control panel operation manual)
◆Automatic transfer panel (optional): is the automatic
transfer switch for transfer between generator set
and mains.(details refer to control panel operation
manual)
2.9
Battery
Our generator set standard configuration provides
start battery as accessory parts. According to user's
different requirements, our company can provide
two types of batteries, that is high efficient plumbous
acid battery and maintenance free battery.
If maintenance free battery is used, users only need
to connect cables for the battery.
If plumbous acid battery is used, before being used,
users need to use standard battery to electrolyze
primary liquid. Untighten the battery cover, slowly
pour electrolyte into the battery until the electrolyte
level reach the indicating line in the internal polar
plates(not allow to exceed this line), then take off the
lable from the battery cover's air hole and close the
cover. After the electrolyte being added, please don't
use it immediately, keep the battery in static status
for thirty to sixty minutes. In low temperature
environment, this time period need to be extended
(use battery charger to charge battery when
necessary)
Users can use the standard connecting cable
attached with the generator set, the red color shall
be connected to positive polar, black (or blue) to
negative polar, correctly connect to the generator
set's start motor . Most of the diesel generator sets'
cables have been connected to the engines before
shipment.
The energy storage capacity of the start battery will
determine if the diesel engine generator set can
smoothly start in a specified period. During the
process of generator sets running, the charging
alternator installed in the engine will continuously
charge battery to start battery.
Warning:
! Please ensure the connection for positive and
negative polar is correct. Wrong connection will
cause malfunction! (Wrong connection will surely
cause damage to the charging alternator)
! When generator set is running, battery cables are not
allowed to be cut down!
