Unauthorized or untrained personnel can misuse unattended tools.
Store idle tools in a dry, high or locked-up place, out of the reach of children.
Misused tools can cause injury.
Tools with the actuator left in the “ON” position when an unexpected air pressure loss occurs can start unexpectedly when the air
pressure is restored.
Release the actuator if an unexpected loss of air pressure occurs.
Unexpected tool starts can cause injury.
The use of any accessory with this tool not provided or specified by Sioux Tools can perform unpredictably.
Use only accessories provided or specified by Sioux Tools.
Tools that perform unpredictably can cause injury.
Avoid exposure of hazardous substances deposited on the tool.
When disposing of a tool, do it in a way that does not harm personnel or the environment.
INTENDED USE
This tool is intended to be used for grinding metal and other non-explosive materials. It is intended to use type 27, depressed center grinding wheels for
metal removal. It is not to be used with cone wheels, cup wheels, straight wheels or cut-off wheels. THE GUARD MUST BE IN PLACE AT ALL TIMES!
AIR SUPPLY
The efficiency of the tool is dependent on the proper supply of clean dry air at 90psig (6.2bar). The use of a line filter, pressure regulator and lubricator
will ensure maximum output and service life of tools.
HOSE AND HOSE CONNECTIONS
The sir supply hose recommended is 3/8" (10mm) I.D. If an extension hose is necessary, use ½" (13mm) I.D. hose with couplings not less than 3/8"
(10mm) I.D.
LUBRICATION
All models may operate without airline lubrication. However, operating the tool without airline lubrication may reduce tool performance and vane life. If
an airline lubrication is not used, it is recommended that the tool be oiled daily before use to improve performance. Add 2-4 drops of SIOUX No. 288
air motor oil and run the tool for 10-20 seconds to distribute the oil through the tool. For maximum performance and tool life, an airline lubricator, set to
deliver 1-2 drops per minute is recommended.
OPERATION
Grind steadily without excessive slowing down of the grinder to prevent wheel damage which could result in wheel breakage. Grind at as uniform load
speed as possible to prevent excess wear, especially on governor parts. A dropped or severely bumped wheel must be correctly examined before
reusing. Do not drop the end of the hose on a floor where it will pick up dirt and transport it into the tool, causing excessive wear and governor sticking.
Provide a stand for holding the grinder when not in use. Fasten wheels and pads securely. Depressed center wheels of 7" & 9" diameter and cup
wheels are to be mounted with 120 in-lb. (10 ft.-lb.) of torque min. to prevent wheel spin-off.
OVERSPEEDING
If overspeeding occurs, the grinder MUST BE REPAIRED and WORN PARTS REPLACED. (GRINDERS MUST BE CHECKED DAILY WITH A
TACHOMETER.)
MAINTENANCE
Water, dust and other airline contaminants can cause rust and vane sticking. For long periods between tool use, flush the tool with a few drops of
oil and run for 10 seconds. This will help remove contaminants and reduce the formation of rust. Check the speed of the tool regularly by placing a
contact type tachometer to the chuck. In addition, always check the speed and do a simple vibration check after any servicing. If the tool exceeds the
rated speed or vibrates excessively, discontinue use and contact an Authorize Sioux Service Center.
WARNING
Disconnect tool from air supply before installing or removing wheel or making any adjustments
