General Usage Description

 

 

This 

Mastercraft® 

Air Compressor with LCD Display is ideal for a host of nailing, fastening and other pneumatic 

tool applications. The advanced digital control panel allows for easy reading and simplifies usage. It features an 
11-gallon (41.6 litre) tank, a 5.5 hp (peak) oil-less pump (which requires less maintenance) wheels and a dolly-style 
handle for easy transportation. It comes standard with a 25’ coil hose and 7 other fittings and accessories so that it’s 
ready-to-use with a minimum of assembly, right out of the box. Ideal for both automotive and home-improvement 
applications. 

 

Compatible Compressor & Air Tool - Guidelines for Proper Usage & Operation 

 
Always ensure the use of appropriately matched air tools with your Mastercraft

®

 Air Compressor with LCD Display.   

Be sure that the air compressor being used can supply the appropriate volume, pressure and delivery rate of air to 
the tool(s) without running continuously. Using tools or combinations of tools that together or separately require 
more than the air compressor can deliver will void the compressor guarantee/warranty. 

 

 

EXTENSION CORDS

:  

Avoid the use of extension cords whenever possible.    If an extension cord 
must be used, it must have a minimum wire size of 12 AWG, and must be no 
longer than 50’ (15 m). Use only a 3-wire extension cord that has a 
3-pronged grounding plug, and plug it into a 3-holed outlet that is suitable for 
the compressor’s plug. 
 
Whenever possible, utilize a longer air hose instead of an extension cord. 
 
 
 
 

Before You Start

 

– Air System:

 

 
1.  A filter-regulator-lubricator is recommended and should be located as close to any air-powered tool as possible. 

(see Fig.4) 

2.  If a filter-regulator-lubricator is not installed, place 2-6 drops of compressor oil into the NPT inlet plug of your 

air-powered tools before each use. 

3.  If installed, keep air filter clean. A dirty filter will reduce the air pressure to the tool causing a reduction in power, 

efficiency and performance in general. 

4.  For better performance, install a quick connector in your tool and quick coupler on the hose. 
5.  Be sure all connections in air supply system are sealed to prevent air loss.
