Q.
What P.S.I. (pounds per square inch of air pressure) does my pneumatic tool require?


A.
All pneumatic tools should be run at 90 P.S.I. gauged at the tool with the tool running.  

Q.
What is the CFM (cubic feet per minute) of my tool?

A.
CFM ratings vary as horsepower increases or decreases, for example, .3hp=16 CFM; .6hp=30 CFM; .9hp=38CFM.
 
Q.
Should I use filtered air?

A.
Dry filtered air is desired. Air with moisture in it will cause tools with blades / vanes to swell.

Q.
Do the tools require airline lubrication?

A.
Yes, all pneumatic assembly tools do require airline lubricant.

Q.
How do I select a drill that’s right for me?

A.
Ask yourself these questions in order to make a proper selection.
What type of material is being drilled?
What size of hole will need to be drilled?
What are your horsepower requirements?
What speed requirements do you have?

Q.
What is Torque?

A.
The word torque comes from the Latin word torquere, which means "to twist." It’s a good choice of words, because it’s the twisting or turning force applied to the nut or bolt that we call torque.

Torque is defined as the force you apply times the distance between the point of application and the axis around which you turning Torque = force x distance.

Torque is commonly measured in foot-pounds or inch pounds. In the metric system it’s measured in Newton meters, the Newton being the standard force in the metric system.

It’s useful to distinguish between two types of torque: Dynamic Torque, which is the torque being exerted by a tool, moment by moment, as it tightens a fastener; and Static Torque, which is the torque required to restart a previously tightened fastener.

Q.
What torque ranges does your Pneumatic Assembly Product Line offer?

A.
The torque range varies based on the tool product line and series. (Tool configurations: straight, right angle and pistol grip). The torque ranges will be from one inch pound up to 5000 foot pounds.  
    
Q.
How do you adjust the torque settings on your assembly tools?

A.
Shut-off style tools, inline or pistol grip are adjusted externally by simply rotating the clutch mechanism clockwise to increase torque and counter clock wise to decrease torque. Non-clutch tools such as stall types are adjusted by air pressure only.

Q.
How do I select a screwdriver that’s right for me?

A.
Ask yourself these questions in order to make a proper selection.
What is being assembled?
What material is involved?
What type of screw or nut is being driven? What head type?
What screw size (standard or metric)?
What U.S. grade or metric class?
What torque (inch pounds or Newton meters)?
What torque tolerance (accuracy)?
What is the run-down torque vs. seating torque?
What type of joint pull-up (hard, medium, soft)?
What pull-up conditions (free run-down, sheet metal, wood, or plastic)?
What is the production rate?
Are there clearance problems?
What handle style is required (straight or pistol)?
Is the tool to be hand held or fixtured?
What type of clutch?
Speed required?
Is there a need for a reversible tool?
What type of drive (square, 1/4" hex, quick change)?
How is the application being done now?
Special consideration?

Q. 
Explain the differences in the clutch options offered on pneumatic assembly tools.

A. 
Clutch options are as follows:
Direct/Stall Clutch - Final torque equals stall torque of motor/gearing.
Simple, low-maintenance design.

Positive Clutch - Simplest screwdriver clutch.
Torque builds up in fastener if the operator allows clutch to continue to impact, No adjustment of clutch is required.

Adjustable Clutch - Tool ratchets on fastener, causing additional torque build-up. Dependable general-purpose clutch.

Torque Control - High torque accuracy.
Conserves air due to automatic shut-off.
Quick fastener run-down.

Q.
How do I choose the right Impact Wrench?

A. 
In order to select the correct tool for an application, it is necessary to know what the job is…
Screw, bolt, or nut size
Grade designation
Torque specifications
Accuracy requirements

Q.
What happens if my tool vibrates excessively?

A.
Check the quality of the collet if a die grinder and the pad if a disc sander.

Q.
What about excessive heat?

A.
If lubrication is adequate, your tool may need repair.

Q.
Where do I get my tool repaired?

A.
You can repair the tool yourself by disassembling and ordering parts from the parts pages included in the original box or view service centers at  HYPERLINK "http://www.siouxtools.com" www.siouxtools.com.

Q.
What if the tool slows down and/or loses power.

A.
Make sure of lubrication, if adequate your tool may need repair.
Also check the air supply for 90 PSI and adequate SCFM.

Q.
What is the warranty?

A.
Sioux offers a 1-year conditional warranty. Parts and workmanship are covered,
however wear and abuse are not
.
