SIOUX IW150 SERIES IMPACT WRENCH
We consider the Sioux IW150 series impact wrench to be an extra heavy duty tool used for steel erection, mining, MRO,
heavy duty assembly/disassembly and construction applications. The heart of the IW150 is the rugged and reliable twin
hammer clutch, encased in a rugged steel clutch housing. Following a few simple guidelines will greatly extend the life of
your tools.
FIRST AND FOREMOST:
The use of other than genuine Sioux replacement parts may compromise your tools performance, operator safety, and also
lead to higher than normal maintenance and repair requirements.
ADDITIONALLY:
1. All Sioux IW150 impact wrenches are designed to be operated on 90 PSI (6.2 bar) air pressure, with clean dry air, and a
minimum 3/4" ID air hose. Using higher air pressure to increase torque output will drastically shorten tool life.
2. Air tool lubrication is critical to achieving the maximum performance and life from your air tools. We strongly suggest
daily lubrication thru the air inlet, or if using an inline lubricator, install it as close to the tool as possible. One drop of oil
per minute is adequate lubrication for most air motors.
3. Proper lubrication of the Impact Clutch mechanism must also be maintained. This unit is equipped with a pressure
feed lubrication system and may be re-greased thru the fitting in the throttle handle. Use caution when using high
pressure lubrication equipment to lubricate the clutch as too much grease can cause a loss of torque output. We
recommend the use of a high quality impact grease such as Sioux Catalog No. 289A grease or an equivalent. (Lubri-
cate once a week during normal use).
4. The way impact tools are used may cause some fasteners to loosen, leading to tool failure. Daily inspect all bolts,
screws, and threaded fasteners to be sure that they are properly tightened.
5. All Sioux air tools should be operated and maintained in accordance with American National Standards Institute Safety
Code for Portable Air Tools (ANSI B 186. 1) and any other applicable safety codes and regulations. ANSI B186.1
information is available from National Standards Institute, Inc., 11 W 42nd Street, New York, NY 10036.
6. Projectile Hazards: Always wear safety glasses to prevent loss of sight or eye injury from flying projectiles when operat-
ing power tools. Do not use Hand Sockets -use only Impact Sockets in good condition. Hand and/or worn sockets can
shatter causing serious injury! Never operate the tool off of the work. It may run too fast and cause the accessory to be
thrown off the tool. Always use the simplest hook-up possible. Long, springy extension bars and adapters absorb
impact power and could break. Use deep Impact Sockets wherever possible in place of extension bars.
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 which may have accumulated.
SOCKETS
Use only impact sockets in good shape.
Use deep socket rather than extension bars.
Ensure that the socket is held square to the fastener and that the tool is in-line with the socket.
