Air Tool Hook Up
be a flexible hose in order to isolate movement of the compressor.
Route the initial
Slope the main lines down at least 3/4 inch per 10 feet of pipe away from air compressor; this will draw the condensate with the flow of air and away from the compressor.
The Craftsman 3/8" Drive Ratchet Wrench is designed to operate on 90 PSIG. Lower pressure (below 90 PSI) will reduce performance of the tool while higher air pressure (over 90 PSI) raises the performance of the tool beyond its rated capacity and could cause serious damage to tool and user.
Speed Adjustment
Before the tool is connected to the air supply, clear the air hose of accumulated dust and moisture by running air freely through the air hose for
Air Hoses for your Air Tools
Figure 1 Illustrates a recommended air hose hook up.
A 3/8 inch ID air hose is required up to a length of 25 feet. A 3/8 inch ID hose longer than 25 feet will cause a pressure
drop and may impede performance. If more length is required, a ½ inch ID air hose is recommended. Be sure all hoses and fittings are the correct size and correctly secured before using the tool.
Never carry a tool by the hose or pull the hose to move the tool or a compressor. Keep hoses away from heat, oil and sharp edges. Replace any hose that is damaged, weak or worn.
Small (home) shop hard piping:
A piping diagram for a typical home shop is shown. Some helpful tips are:
Always use hoses and pipes rated for higher pressure than your system will encounter.
Never use PVC pipes for compressed air piping systems as explosion and serious injury may result.
The connection from the compressor to the initial
Place the first drop as far from the compressor as the size of your shop will allow (50 feet is optimal, although unrealistic for a small shop). The further the drop, the more that condensation can occur, and the drier the air will be when it reaches the water separator.
In order to reduce the amount of water and contaminants that get into the water separator, install the take- off line on the top of the main air supply line for each air drop.
A Drain line should be placed at the end of the main line for condensate drainage.
Drain valves should be placed at the end of branch lines and the drain line, and drained daily.
The ratchet should never be used to set the torque. Use a torque wrench to set the torque.
When tightening, do not torque down the nuts or bolts with the ratchet as typically done with a hand wrench. This
can damage the tool by breaking parts
in the ratchet mechanism.
