WARNING

 

 

1

 

Never exceed 25 PSI during operation. 

2

 

Do not leave exposed to the elements, heat sources, or direct 
sunlight for extended periods. Sun light has adverse effects 
on the integrity of the tank plastic and thermal expansion 
from heat may increase the pressure well beyond 25 PSI. 

3

 

Do not interchange between mineral based fluid types and 
phosphate ester-based fluid types. 

4

 

Use appropriate personal protective equipment (PPE). 

5

 

To prevent ejected pump assembly and/or fluid from striking 
and injuring operator, never stand with face or body over top 
of tank when pumping or loosening pump. 

6

 

Never power-up, pressurize under power, or operate an aircraft 
hydraulic system with this servicing pump connected. This can 
over-pressurize the service pump and cause it to explode.

Overview 

This oil under air pressure tank is designed to be a light weight, 
efficient, and versatile fluid servicing unit. It eliminates any 
pressurization actuation during use and can be easily held with one 
hand. The operator controls the flow via a small valve and is free 
to observe fluid levels. Any need for an assistant to actuate a 
heavy pump on the ground is eliminated. This concept makes the 
operation as efficient, ergonomic, and time conserving as possible. 
Less bulk also means more stability on a work stand or ladder and 
promotes a safe work environment.
