INSTRUCTIONS & PARTS LIST FOR
1410 & 1412 AIR DRILLS
Printed In U.S.A.
AIR SUPPLY
The efficiency of the tool is dependent on the proper supply of clean dry air at about 90 psig.
The use of a line filter, pressure regulator, and lubricator will insure maximum output and
service life of tools.
Before connecting the tool, blow the air line to remove water and dirt which may have accumu-
lated. This is especially important for a new line or when the line has not been used for some
time.
HOSE AND HOSE CONNECTIONS
Supply hose should be not less than 5/16" I.D. Extension hoses should be at least 3/8" I.D.
Use couplings and fittings with at least 5/16" I.D.
LUBRICATION
An airline lubricator, set to deliver one drop per minute, is recommended. If a lubricator is not
used, about one fourth teaspoon of oil should be poured into the air inlet daily. SIOUX No. 288
air motor oil, which contains a moisture absorbent and rust preventative, is recommended.
The gearing is lubricated with SIOUX No. 1232A grease and should be greased every 50
hours of operation.
GENERAL OPERATION
This tool is equipped with a teasing throttle. By slightly depressing the trigger the chuck will
rotate slowly. This is useful for starting a drill bit without first spotting with a punch. By fully
depressing the trigger the chuck will rotate at its top speed.
A speed control adjusting screw is located on the trigger face and is adjusted with a 1/16” Allen
wrench.
