Use and Care Manual

AIR PRESSURE AND VOLUME
• If the tool is not performing to specifications as listed in the JET catalog,
check the following:
Check the air compressor to see that it has the CFM output to support
the air tool.
Check compressor regulator settings.
Check to see if the air transmission lines are too small.
Check to see if the air hose is too small.
Check to see if hose fittings and couplings are too small.
• Refer to the catalog specifications for proper air hose size. Use hose that is
just long enough to serve the working area. Excessive lengths of hose will
cause a drop in pressure.
COMMON PROBLEMS
• Contaminated air such as a dirty air system or water in the system.
• Using the wrong size tool for the job.
• Poor maintenance practices, such as using excessive air pressure or air
volume.
• Improper or no lubrication.
RULE OF THUMB
• If it takes more than 8 seconds to tighten or loosen a bolt or nut with an air
impact wrench, the air wrench is too small or the air compressor CFM is not
powerful enough for the job. Continued use in either capacity will cause
damage to the tool.
TOOL PRESSURE
• All JET Air Tools operate on 70-100 PSI air pressure (90 PSI preferred)
measured at the tool when the tool is operating. Pressure in excess of 100
PSI will shorten the life of the tool and cause unnecessary down time.
Air tools, as well as tools with moving parts, require attention from time to time.
The following information will assure proper performance.
SAFETY WARNINGS
• Never allow an air tool to operate at full throttle without a work load on the
tool.
• Never start a percussion type air tool (chippers, breakers, buster, etc.)
without securing the tooling in the retainer and placing the tip against the
work surface.
• When operating an air grinder, place the abrasive wheel against the work
surface immediately after starting.
• Never operate an air tool without the guards in place.
• Never operate any air tool without proper eye and hand protection.
• Some dust created by power sanding, sawing, grinding, drilling and other
construction activities contains chemicals known to cause cancer, birth
defects or other reproductive harm. Some examples of these chemicals are:
- Lead from lead-based paint.
- Crystalline silica from bricks and cement and other masonry products.
- Arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this
type of work. To reduce your exposure to these chemicals, work in a well-
ventilated area, and work with approved safety equipment, such as those
dust masks that are specifically designed to filter out microscopic particles.
LUBRICATION
• Use a light oil containing rust inhibitors, such as SAE #5W, SAE #10W, or
JET Marvel
®
Air Tool Oil. Many JET Air Tools have integral oil reservoirs,
which should be kept filled when in-line oilers are not used.
• Use a grease that is highly water resistant for the front case components on
air impact wrenches, grinders and sanders.
AIR SYSTEM
• Make sure the compressor being used with the air tool supplies adequate
output (CFM).
• Equip the air compressor intake with a replaceable air filter that can be easily
cleaned.
• Always use moisture traps at the compressor for the main distribution line.
Use moisture traps and in-line oilers on each downline that is to be used for
air tools. (See Figure). Place oiler as close to the air tool as possible for the
best lubrication.
