air

 

compressors

 

by

 

number.

When

 

a

 

new

 

replacement

 

is

 

needed

 

include

 

the

 

model

 

number

 

of

 

the

 

air

 

compressor,

 

part

 

number

 

and

 

quantity

 

required.

If

 

a

 

new

 

assembly

 

is

 

required,

 

include

 

the

 

model

 

number

 

of

 

the

 

air

 

compressor

 

undergoing

 

repair

 

(according

the

 

nameplate),

 

the

 

part

 

name,

 

part

 

number

 

and

During

 

the

 

break-in

 

period,

 

nuts

 

and

 

bolts

 

have

 

a

 

tendency

 

to

 

loosen

 

up.

 

After

 

two

 

weeks

 

tighten

 

ail

 

nuts

 

and

 

bolts

 

including

 

head

 

bolts.

all

 

nuts

 

and

 

bolts

 

stay

 

tight.
