Maintenance and Usage Tip

•Each tool requires: 87 PSI (0.6Mpa / 6 bars); however the range of 85-90 PSI is acceptable.

(6 kg / cm2) of air pressure and 15 CFM (420 l / min.) of air ﬂow.

•We suggest a minimum of 5 HP air compressor with a holding tank of 50 cubic feet (1,400 l) capacity for one tool.

•Air hose ﬁtting is 1/4” BSPP

•The use of heavy duty 3/8” (10mm) hose is suggested for all lines.

LUBRICATION (Lube Oil is used to protect the tool from rusting when not in use)

PROPER CARE AND LUBRICATION ARE IMPORTANT FACTORS IN THE USEFUL LIFE OF THIS TOOL.

At the end of each workday, 2-3 drops of lubricant oil, solvent free oil (included with each polisher) should be placed in the air inlet at the base of the tool. Rotate the spindle counter clockwise, by hand 3-4 revolutions. Reinstall the air hose and run the tool for a minute or two. (Replacement containers of oil may be purchased from Alpha Professional Tools® Part # AIR-008.)

Automatic oilers are not recommended: the volume, grade, and composition of oil used may cause premature failure. In-line air dryers are recommended to extend the life of the tool. Old or worn compressors, which emit oil through the air lines, can dramatically shorten the life of the tool.

SPINDLE SIZE

The Alpha® AIR-658 air polisher features a 5/8”-11 size spindle. This tool has been designed for portable/shop production and uses all modern accessories. It is very important that you do not run anything heavier than the recommended accessories on this machine. A drop of oil should be applied to the outside threads whenever attachments are changed to facilitate removal and prevent rust. A 22mm Spindle Wrench is provided to assist in changing accessories.

Maintenance and Usage Tip

•Do not leave the tool submersed in water. This could expose the inner moving parts to moisture, which will shorten the life of the tool.

•Do not leave threaded accessories (backer pads, core drill bits, proﬁlers) on the spindle of tool for extended periods of time; this may result in making it difﬁcult to remove these accessories.

•Excessive force or impact to the spindle may result in premature failure of gears and/or bearings, which may not be immediately evident.
