Never lay a tool down until the attachment has stopped moving.
Do not overreach. Keep proper footing and balance at all times.
Do not allow bystanders to contact tool.
Keep bystanders at a safe distance from the work area.
Wear appropriate protective apparel, users and bystanders.
Direct exhaust air to avoid blowing air or debris from the workpiece onto the user or bystanders.
When operating in heights, be aware of things below and around you.
When tool is not in use, shut off the air supply and press trigger or lever to relieve air pressure.
If tool is not to be used for a period of time, lubricate it, disconnect it from the air supply line and store it in a dry place with
moderate temperature.
Store tools when not being used in a high, dry and locked area that can not be accessed by children.

Work area hazards can cause injury.

Risk of whipping compressed air hoses.

Attach air lines securely.
Check the air hose and fittings regularly for wear.
Do not connect quick-connect couplings directly to the tool.
Use a whip air hose no longer than 60" (150 cm).

Whipping compressed air hose can cause injury.

Untrained users can create hazards.

Secure work with a clamp or a vise whenever possible.
Use the right tool. Do not use a tool that is too light or too heavy for the work.
Do not force tool.
Operate air tools at 90 psig (6.2 bar, 620 kPa) maximum air pressure.
It is expected that users adopt safe working practices and observe all local, regional or country legal requirements when
installing, using or maintaining this tool.

Improper use can cause injury.

Improper repairs or lack of maintenance can create hazards.

Do not modify or make temporary repairs. Use only genuine Snap-on replacement parts for maintenance and repair. Servicing
and repairs should be performed only by trained personnel.
Do not use the tool if it vibrates too much, makes unusual noises, has loose parts, or shows any other sign of damage.
If tool malfunctions, discontinue use and immediately arrange for service and repair. If it is not practical to remove the tool from
service, shut off the tool air supply, write a warning tag and attach the tag to the tool.
Do not remove any manufacturer fitted safety devices (e.g., wheel guards, safety trigger, speed governors).
If this tool becomes damaged beyond repair, disassemble and degrease the tool. Then separate all parts by material type and
recycle.

Improper parts, repair or maintenance can cause injury.

WARNING

Using damaged and incorrect sockets or accessories can cause flying particles.

Do not use chipped, cracked or damaged sockets or accessories.

Use only ball-joint flexible sockets. Do not use square block type flex sockets.

When using extensions, hold air ratchet so that socket fits straight on the fastener.

APPLICATIONS

The Sioux SWR03S Series Air Ratchet is a rugged, variable speed, reversible air ratchet that is ideal for many confined automotive and industrial
applications.

It is designed and built to make fast work of light duty fastener turning jobs that do not require more than 35 ft.lb. (47 N•m) torque.

AIR SUPPLY

The efficiency and life of this tool depend on the proper supply of clean, dry air at a maximum of 90 PSI. The use of an air line filter, pressure regulator,
and lubricator is recommended.

Before connecting to tools, blow out the air line to remove water and dirt that may have accumulated.

AIR COMPRESSOR

The air compressor should have sufficient capacity to deliver 3.8 cfm (27 SCFM) at 90 psig (6.2 bar, 620 kPa) at each outlet while the tool is running.
The receiver tank should have sufficient capacity to provide surge balance for each air tool.

FILTER

A filter should be used to assure clean air for the tool. Water, dirt and scale act as abrasives which could damage the air tool. A filter unit should be
installed between the compressor and the air regulator and air lubricator.

AIR STRAINER

An air strainer is built into the removable air inlet bushing located at the rear of the ratchet. To clean, remove the bushing and use an air hose to blow
dirt and other particles from the screen and bushing. Torque the air inlet bushing to 100 in. lb. (11.3 N•m).

INSTALLING SOCKETS

The SRW03S-38 uses 3/8" square drive sockets. The SRW03S-25 uses 1/4" square drive sockets. Be sure that only power or impact sockets are used.

TRIGGER

A trigger controls the air flow valve, which regulates the power and speed of the ratchet. The button provides for variable low speed control with
feathering ability and progressive, high speed control for high torque requirements. The distance of trigger movement directly controls the amount of air
flow to the air motor.

REVERSE MECHANISM

The direction of rotation is determined by the position of the selector knob in the drive body. Be sure the selector knob is positioned fully in either
direction before depressing the trigger. Turning the selector knob to the left turns the nut or bolt in a clockwise direction.

SERVICE INSTRUCTIONS

Refer to parts listing. Use only genuine Sioux replacement parts for maintenance and repair. Servicing and repairs should be performed only by trained
personnel.

Use only power or impact sockets and accessories.

Flying particles can cause injury.

Form Z812 2 Date 2013November19/B

HOSE AND HOSE CONNECTIONS

The air supply hose recommended is 3/8" (10mm) I.D. If an extension hose is necessary, use 1/2" (13mm) ID hose with couplings not less than 3/8"
(10mm) I.D.

LUBRICATION

All models may operate without airline lubrication. However, operating the tool without airline lubrication may reduce tool performance and vane life.
If an airline lubrication is not used, it is recommended that the tool be oiled daily before use to improve performance. Add 2-4 drops of air motor oil and

run the tool for 10-20 seconds to distribute oil through the tool.
For maximum performance and tool life, an air line lubricator, set to deliver 2 drops per minute, is recommended. SIOUX No. 288 Air Motor Oil is

recommended.

For Ratchet Mechanism Lubrication

Lubricate the ratchet head assembly with 2 shots of SIOUX #1232A grease every 8 working hours.
Inject grease through the flush-type fitting on the selector knob until fresh grease becomes visible on both sides of the ratchet head.

MAINTENANCE

Water, dust and other airline contaminants can cause rust and vane sticking. For long periods between tool use, flush the tool with a few drops of oil
and run for 10 seconds. This will help remove contaminants and reduce the formation of rust.

OPERATION

Speed of the tool may be adjusted by turning the regulator, which is located opposite the throttle lever.

WARNING

Disconnect tool from air supply before installing or removing sockets or making any adjustments
