INSTRUCTIONS FOR 1291, 1291LK, 1291L GRINDERS
Read and understand "Safety Instructions For Air Tools" and these instructions before
Grinders without guards do not provide protection from exploding grinding wheels.
AIR SUPPLY
The efficiency of the tool is dependent on the proper supply of clean dry air at 90 psig (6.2 bar). The use of a line filter, pressure regulator,
and lubricator will insure maximum output and life of tools. Before connecting tool, blow out the air line to remove water and dirt that may
have accumulated.
HOSE AND HOSE CONNECTIONS
Supply hose should be not less 3/8" (10 mm) I.D. Extension hoses should be at least 1/2" (13 mm) I.D. Use couplings and fittings with at
least 3/8" (10 mm) I.D.
LUBRICATION
Use SIOUX No. 288 air motor oil. An airline lubricator, set to deliver 1 to 2 drops per minute, is recommended. If a lubricator is not used, add
.08 oz. (2.4 cc, 25 to 30 drops) of oil to the air inlet twice daily.
Inject Sioux No. 1232 grease through the grease fittings after every 40 hours of operation.
GENERAL OPERATION
CHECK THE TOOL DAILY WITH A TACHOMETER!
Start the tool by depressing the trigger or lever.
Always remove the tool from the air supply before installing or changing grinding wheels!
MOUNTING WHEELS
Cup grinding wheels and 7" & 9" depressed center grinding wheels must be tightened to 120 in-lb. (1.4KG-M) to keep wheels from spinning
off.
7" & 9" depressed center grinding wheels are mounted to the tool with the No. 510 holder. Screw the 510 holder on to the spindle. If
necessary, place the 25894 washers between the holder and the tool drive flange to adjust for wheel thickness. DO NOT place the
washers directly between the wheel and the holder. Install the wheel and secure with the 512 Holder Nut. Torque the nut to 120 in-
lb.(1.4KG-M).
