IMPACT WRENCH SAFETY
Impact wrenches can cause flying particles.
Proper eye protection must be worn at all times by tool user and bystanders.
Flying particles can cause eye injury.
Sockets, bits and adapters not made for power tools can break when used with power tools. Sockets, bits and adapters not made for
impact drivers can break when used with impact drivers.
Proper eye protection must be worn at all times by tool user and bystanders. Use only impact sockets, bits and adapters that are
in good condition. Keep hands away from sockets, bits and adapters. Failure of the workpiece, sockets or bits can cause high
velocity projectiles. Ensure that the workpiece is securely fixed.
Broken sockets, bits and adapters can cause injury.
Power tools generate noise.
Ear protection must be worn when tool noise level exceeds 85 dBA.We also recommend that ear protection be worn when the
tool noise level is below 85 dBA. See the tool’s information sheet for the noise level. High noise levels can cause hearing damage.
Damping may help keep workpiece from ringing. Keep the socket maintained to prevent an increase in noise and vibration.
Replace the socket to prevent an increase in noise. Ensure that the impact driver's muffler is still installed.
Prolonged exposure to noise can cause hearing loss.
Power tools vibrate.
Excessive vibration can cause injury. If numbness, tingling, pain or whitening of the skin occurs, stop using tool and consult a
physician. See the tool’s information sheet for the vibration level.Wear warm clothing when working in cold conditions. Keep
your hands warm and dry. Maintain the impact driver as recommended to prevent an increase in vibration levels. Do not use
worn or ill-fitting sockets or extensions, as this is likely to cause a substantial increase in vibration levels. Support the tool in a
stand, tensioner or balancer if possible. Do not hold the tool too tightly. Sleeve fittings should be used where practicable. Keep
the hands away from the sockets, extensions and rotation components.
Prolonged exposure to vibration can cause injury.
Worn, chipped, or cracked sockets, bits, and adapters can break.
Do not use worn, chipped, or cracked sockets, bits, or adapters.
Broken sockets, bits and adapters can cause injury.
Impact wrenches present a risk of entanglement.
Keep loose hair away from power tools and accessories. Keep hands away from moving parts of the tool and accessories. Do not
wear jewelry, loose clothing, or neckwear around power tools. Keep work area clear of cleaning rags and all items that could become
entangled with the tool. Entanglement hazards can result in choking, scalping and lacerations if loose clothing, jewelry, neck wear,
hair or gloves are not kept away from tool. Gloves can become entangled with the rotating drive, causing broken or severed fingers.
Rotating drive sockets an drive extensions can easily entangle rubber-coated or metal-reinforced gloves. Do not wear loose fitting
gloves with cut or frayed fingers. Never hold the drive, socket or drive extension. Keep hands away from rotating drive.
Entanglements can cause injuries.
Driving screws creates dust.
Use respiratory protection. Dust and fumes generated by the impact driver can cause ill health. Consider both dust created
by the tool and existing dust disturbed by the tool exhaust. Direct the impact driver's exhaust to minimize disturbance of dust.
Control dust at the point of emission. All integral features or accessories for the collection, extraction, or suppression of dust
and fumes should be maintained.
Breathing dust created when driving screws can cause injury.

Operators and maintenance personnel should be physically able to handle the bulk, weight and power of the tool. Hold the tool correctly
and be ready to counteract normal or sudden movements and have both hands available. In cases where means to absorb the reaction
torque are requested, it is recommended to use a suspension arm whenever possible. Wear suitable gloves to protect the hands.
Operating an impact drive may expose the operator to injuries.
Repetitive motion hazards are possible when operating this tool.
Operator can experience discomfort in the hands, arms, shoulders, neck or other parts of the body. Use comfortable, not off-
balance posture. Change posture frequently during extended tasks.
If the operator experiences persistent or recurring discomfort, pain, throbbing, aching, numbness, burning sensations or stiffness the
operator should seek medical assistance.
Accessories and sockets attached to the tool can create hazards.
Disconnect the impact driver from the airline before changing accessories. Do not touch sockets or drive extensions during
impacting. This could increase the risk of cuts, burns or vibration injuries. Use only the sizes and types of accessories and tools
recommended by Sioux Tools. Use only impact-wrench-rated sockets in good condition, as poor condition or hand sockets used
with impact wrenches can shatter and become a projectile.
Improper sockets and accessories can cause injury.
Be aware of hazards from your workplace.
Be aware of slippery surfaces caused by the use of the impact driver and avoid trip hazards caused by the airline. Proceed with
care in unfamiliar surroundings. Assembly tool for threaded fasteners should not be used in explosive atmospheres and is not
insulated against contact with electrical current.
Hazards from your workplace may cause injury.
Air under pressure can cause injury.
Shut off air supply, drain hose and disconnect from tool before servicing or changing accessories. Never direct air at yourself or
anyone else. Whipping air hoses can cause severe injury. Always check for damaged or loose hoses or fittings. Cold air should
be directed away from hands. Use lock pins and whipcheck safety cables when u sing universal twist couplings. Do not exceed
the maximum air pressure stated on the tool. Do not carry the tool by the hose. Do not use quick-disconnect couplings at tool
inlet for impact wrenches. Use hardened steel threaded hose fittings.
Wipe all couplers clean before connecting. Failure to do so can result in damage to the quick couplers and cause overheating.
When disposing of a tool, do it in a way that does not harm personnel or the environment.
INTENDED USE
The impact wrench is designed for the tightening and loosening of threaded fasteners within the range as specified by the manufacturer. It should only
be used in conjunction with suitable impact type square female drive nut running sockets. Only use sockets which are of the impact type. It is allowed
to use suitable extension bars, universal joints and socket adaptors between the square output drive of the impact wrench and the square female
drive of the socket. Do not use the tool for any other purpose than that specified without consulting the manufacturer or the manufacturer’s authorized
supplier. To do so may be dangerous. Never use an impact wrench as a hammer to dislodge or straighten cross threaded fasteners. Never attempt to
modify the tool for other uses and never modify the tool for even its recommended use as a nutrunner.
WORK STATIONS
The tool should only be used as a handheld, hand operated tool. It is always recommended that the tool is used when standing on the solid floor. It can
be used in other positions, but before any such use, the operator must be in a secure position having a firm grip and footing and be aware that when
loosening fasteners the tool can move quickly away from the fastener being undone. An allowance must always be made for this rearward movement
so as to avoid the possibility of hand/arm/body entrapment.
GENERAL OPERATION
The output of the impact wrench in prime working condition is governed by mainly three factors:
a) the input air pressure;
b) the time the impact wrench is operated on the joint. Normal time for joints of average tension requirement 3 to 5 seconds;
c) the setting of the air regulator for a given joint at a given pressure operated for a given time.
The air regulator on housing can be used to regulate the (CW) output of the impact wrench if no other means of control is available. It is strongly
recommended that an external pressure regulator, ideally as part of a filter/regulator/lubricator (FRL), is used to control air inlet pressure so the pressure
can be set to help control the tension required to be applied to the threaded fastener joint. There is no consistent, reliable torque adjustment on an
impact wrench of this type. However, the air regulator can be used to adjust torque to the approximate tightness of a known threaded joint. To set the
tool to the desired torque, select a nut or screw of known tightness of the same size, thread pitch and thread condition as those on the job. Turn air
regulator to low position, apply wrench to nut and gradually increase power (turn regulator to admit more air) until nut moves slightly in the direction it
was originally set. The tool is now set to duplicate that tightness, note regulator setting for future use. When tightening nuts not requiring critical torque
values, run nut up flush and then tighten an additional one-quarter to one-half turn (slight additional turning is necessary if gaskets are being clamped).
For additional power needed on disassembly work, turn regulator to its fully open position. Rating must be downgraded for spring U bolts, tie bolts,
long cap screws, double depth nuts, badly rusted conditions and spring fasteners as they absorb much of the impact power. When possible, clamp or
wedge the bolt to prevent springback. Soak rusted nuts in penetrating oil and break rust seal before removing with impact wrench. If nut does not start
to move in three to five seconds use a larger size impact wrench. Do not use impact wrench beyond rated capacity as this will drastically reduce tool
life.
NOTE: Actual torque on a fastener is directly related to joint hardness, tool speed, condition of socket and the time the tool is allowed to impact. Use
the simplest possible tool-to-socket hook up. Every connection absorbs energy and reduces power.
Forward/reverse operation is controlled by reverse switch located above the trigger. Press reverse switch for reverse mode. Press foward switch for
forward mode. Ensure that the reverse switch is in the proper position before starting tool. The air regulator controls the speed of the tool and is located
on the back of housing. For Forward Operation, it is a 4-position regulator with "4" being the highest setting and "1" the lowest setting. Reverse (CCW)
is always in full power setting, regardless of regulator knob position.
The tool incorporates an air inlet bushing. Check periodically as blockage will reduce the speed and power of the tool. To clean the air inlet bushing it is
necessery to remove the air inlet bushing from motor housing.
For best results:
1) Always use the correct size impact type socket.
2) Use extra deep sockets in place of extension bars where possible.
3) Do not use oversized, worn or cracked sockets.
4) Hold the wrench so the socket fits squarely on the fastener. Hold the wrench firmly, but not too tightly, pressing forward slightly.

AIR SUPPLY
Use a clean lubricated air supply that will give a measured air pressure at the tool of 90 p.s.i./6.2 bar when the tool is running with the trigger fully
depressed and the air regulator in its maximum opening flow position. It is recommended that the tool is connected to the air supply as shown in
figure 1. Do not connect the tool to the air line system without incorporating an easy to reach and operate air shut off valve. The air supply should be
lubricated. It is strongly recommended that an air filter, regulator, lubricator (FRL) is used, as shown in Figure 1, as this will supply clean, lubricated air
at the correct pressure to the tool. Details of such equipment can be obtained from your supplier.
LUBRICATION
For maximum performance and tool life, an air line lubricator, set to deliver 4 drops per minute, is recommended. SIOUX No. 288 Air Motor Oil is recommended.
If an airline lubrication is not used, it is recommended that the tool be oiled daily before use to improve performance. Add 4-8 drops of air motor oil and
run the tool for 10-20 seconds to distribute oil through the tool.
MAINTENANCE
Water, dust and other airline contaminants can cause rust and vane sticking. For long periods between tool use, flush the tool with 5 ml of oil and run for
10 seconds. This will help remove contaminants and reduce the formation of rust.
