INSTRUCTIONS AND PARTS LIST FOR
8500 SERIES IMPACT WRENCH
GENERAL SAFTEY RULES
WARNING! READ AND UNDERSTAND ALL INSTRUCTIONS. Failure to follow all instructions listed below, may result
in electric shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS.
WORK AREA
1. Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents.
2. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases,
or dust. Power tools create sparks which may ignite the dust or fumes.
3. Keep bystanders, children, and visitors away while operating a power tool. Distractions can cause you to lose
control.
ELECTRICAL SAFETY
1. Double insulated tools are equipped with a polarized plug (one blade is wider than the other). This plug will
fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does
not fit, contact a qualified electrician to install a polarized outlet. Do not change the plug in any way. Double
Insulated eliminates the need for the three wire grounded power cord and grounded power supply system.
2. Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an
increased risk of electric shock if your body is grounded.
3. Don’t expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric
shock.
4. Do not abuse the cord. Never use the cord to carry the tools or pull the plug from an outlet. Keep cord away
from heat, oil, sharp edges or moving parts. Replace damaged cords immediately. Damaged cords increase the risk of
electric shock.
5. When operating a power tool outside, use an outdoor extension cord marked “W-A” or “W”. These cords are
rated for outdoor use and reduce the risk of electric shock.
PERSONAL SAFETY
1. Stay alert, watch what you are doing, and use common sense when operating a power tool. Do not use tool
while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power
tools may result in serious personal injury.
2. Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing, and
gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts.
3. Avoid accidental starting. Be sure switch is OFF before plugging in. Carrying tools with your finger on the
switch or plugging in tools that have the switch ON invites accidents.
4. Remove adjusting keys or wrenches before turning the tool ON. A wrench or a key that is left attached to a
rotating part of the tool may result in personal injury.
5. Do not overreach. Keep proper footing and balance at all times. Proper tooling and balance enable better
control of the tool in unexpected situations.
6. Use safety equipment. Always wear eye protection. Dust mask, nonskid safety shoes, hard hat, or hearing
protection must be used for appropriate conditions.
TOOLS USE AND CARE
1. Use clamps or other practical way to secure and support the workpiece to a stable platform. Holding the work
by hand or against your body is unstable and may lead to loss of control.
2. Do not force tool. Use the correct tool for your application. The correct tool will do the job better and safer at
the rate for which it is designed. 3. Do not use tool if switch does not turn it ON or OFF. A tool that cannot be con-
trolled with the switch is dangerous and must be repaired.

2
4. Disconnect the plug from the power source before making any adjustments, changing accessories, or storing the
tool. Such preventive safety measures reduce the risk of starting the tool accidentally.
5. Store idle tools out of reach of children and other untrained persons. Tools are dangerous in the hands of untrained
users.
6. Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools. with sharp cutting edges are
less likely to bind and are easier to control.
7. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the
tool’s operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly maintained tools.
8. Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable
for one tool may become hazardous when used on another tool.
SERVICE
1. Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified
personnel may result in a risk of injury.
2. When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance Section of this
manual. Use of unauthorized parts or failure to follow Maintenance Instructions may create a risk of electric shock or injury.
SPECIFIC SAFETY RULES FOR IMPACT WRENCHES
Hold tool by insulated gripping surfaces when perfoming an operation where the cutting tool may contact hidden
wiring or its own cord. Contact with a “live” wire will make exposed metal parts of the tool “live” and shock the operator.
Avoid prolonged exposure to vibration. Prolonged exposure to vibration can cause injury.

EXTENSION CORD SELECTION
If an extension cord is used, make sure the conductor size is large enough to prevent excessive voltage drop which will cause
loss of power and possible motor damage. A table of recommended extension cord sizes will be found in this section. This
table is based on limiting line voltage drop to 5 volts (10 volts for 230 volts) at 150 % of rated amperes.
If an extension cord is to be used outdoors it must be marked with the suffix W-A following the cord type designation. For
example-SJTW-A to indicate it is acceptable for outdoor use.
SWITCH
Pressing the lower part of the switch runs the tool in a forward (right hand thread)
direction. Pressing the upper part of the switch reverses motor direction. This
allows “rocking” fasteners to break them loose.
OPERATION
Position the impact wrench correctly, so that the socket fits straight on the
fastener.
MAINTENANCE
• Blow out air vents with clean dry air periodically.
• Carbon Brushes should be regularly inspected for wear. Be sure tool is
unplugged before inspecting brushes.To inspect brushes, unscrew the
plastic brush inspection caps (located in the sides of the motor housing)
and the spring and brush assemblies may be withdrawn from the tool.
Keep brushes clean and sliding freely in their guides. Replace worn
brushes.
LUBRICATION
This tool has been properly lubricated at the factory and is ready for use. Periodic relubrication will be necessary to
maintain the tool in an efficient operating condition.
It is recommended that you contact your Sioux representative to have the tool lubricated in the following intervals. For
continuous operation, have the tool lubricated after every 30 hours of use. With intermittent work, have it lubricated
after every 50 hours of use. Use Sioux 1236 grease in impact mechanism assembly.
ACCESSORIES
Use only socket designed for use with impact wrenches. CAUTION: The use of any other attachment or accessory
might be hazardous.
