‘s

 

discharge

 

valve

 

and

 

the

 

engine’s

 

discharge

 

valve

 

are

 

tightly

 

closed.

 

◆

Add

 

the

to

 

the

 

system

 

in

 

a

 

proper

 

speed

 

so

 

that

be

 

discharged

 

through

 

the

 

adding

 

hole

 

or

 

the

 

discharge

 

valve

 

in

 

the

 

engine

 

body.

 

If

 

the

is

 

furnished

 

with

 

heater,

 

the

 

control

 

valve

 

for

 

the

 

heater

 

shall

 

be

◆

When

 

adding

 

the

 

coolant,

 

the

 

surface

 

of

 

liquid

 

shall

 

reach

 

to

 

the

Lubricant

 

system

 

Lubricant

 

system

 

is

 

composed

 

of

 

oil

 

pan,

 

oil

 

pump,

 

strainer,

of

 

the

 

engine

 

and

 

all

 

kinds

 

of

 

lubricant

 

parts

 

which

 

are

 

in

 

relative

 

motion

 

etc.

   

The

 

main

 

purpose

 

of

 

the

 

lubricant

 

system

 

is

 

to

 

provide

 

sustained

 

tempered

 

oil

 

film

 

between

 

the

 

parts

 

which

 

are

 

in

 

motion

 

so

 

that

 

to

 

reduce

 

friction

 

and

 

wear,

 

and

 

draws

 

off

 

part

 

of

 

the

 

heat

 

absorbed

 

by

 

the

 

parts,

mechanical

 

part,

 

improve

 

sealing

 

effect

 

and

 

prevent

 

rust

 

from

 

each

 

part’s

 

surface.

 

Users

 

can

 

determine

 

the

 

model

 

of

 

lubricant

 

according

 

to

 

the

 

specific

 

working

 

environment

 

and

 

conditions.

 

For

 

the

 

first

 

time

 

lubricant,

 

normally

 

users

 

shall

 

change

 

it

 

within

 

100

 

hours

 

upon

 

and

 

from

 

the

 

time

 

when

 

the

 

generator

 

set

 

first

 

started.

viscosity

 

and

 

conform

 

to

 

the

periodically

 

change

 

the

 

lubricant

 

oil

 

and

filter

 

so

 

that

 

to

 

ensure

 

the
