INSTRUCTIONS FOR:
SUPER DUTY 1/2” COMPOSITE AIR
IMPACT WRENCH
MODEL NO: 24400
IMPORTANT: PLEASE READ THESE INSTRUCTIONS CAREFULLY. NOTE THE SAFE OPERATIONAL
REQUIREMENTS, WARNINGS AND CAUTIONS. USE THIS PRODUCT CORRECTLY AND WITH CARE
FOR THE PURPOSE FOR WHICH IT IS INTENDED. FAILURE TO DO SO MAY CAUSE DAMAGE
AND/OR PERSONAL INJURY AND WILL INVALIDATE THE WARRANTY. PLEASE KEEP
INSTRUCTIONS SAFE FOR FUTURE USE.
Follow all workshop safety rules, regulations, and conditions when using wrench.
WARNING! Disconnect from air supply before changing accessories or servicing.
Maintain the wrench in good condition and replace any damaged or worn parts. Use genuine
parts only. Unauthorized parts may be dangerous and will invalidate the warranty.
WARNING! Check correct air pressure is maintained and not exceeded. We recommend
90psi.
Keep air hose away from heat, oil and sharp edges. Check air hose for wear before each
use and ensure that all connections are secure.
Only use impact sockets which are specifically designed for use with an impact wrench.
Wear approved safety eye/face shield, ear defenders and hand protection.
WARNING! Due to the possible presence of asbestos dust from brake linings, when working
around vehicle brake systems we recommend you wear suitable respiratory protection.
Maintain correct balance and footing. Ensure the floor is not slippery and wear non-slip
shoes.
Keep children and non essential persons away from working area.
DO NOT use the wrench for a task it is not designed to perform.
WARNING! DO NOT use wrench if damaged or thought to be faulty. Contact Service Agent.
DO NOT use wrench unless you have been instructed in its use by a qualified person.
DO NOT carry the wrench by the air hose, or yank the hose from the air supply.
DO NOT operate wrench if you are tired or under the influence of alcohol, drugs or
intoxicating medication.
DO NOT direct air from the air hose at yourself or others.
When not in use disconnect from air supply and store in a safe, dry, childproof location.
Combination of composite materials, alloyed metals and twin hammer design result in a
lightweight, durable and powerful air impact wrench. Soft-grip handle with downward facing
exhaust make this wrench comfortable on the hands and ears and limits the circulation of
brake dust on wheel applications. Finger tip control of power and direction via lever on rear of
wrench. Suitable for professional garage use.
Working/Maximum Torque:…750 Ft.Lb. Operating Pressure:…………90 psi
Max Torque:…………………..950 Ft. Lb. Air Inlet Thread:………………3/8”
Air Consumption:……………..36 SCFM Weight:…………………………4.58 Lbs
Noise Power:………………….96.2 db.A Drive:……………………………1/2” Sq.
Clutch Type:………………Twin Hammer

WARNING! Ensure the air supply is clean and does not exceed 90 psi while
operating the wrench. Too high an air pressure and/or unclean air will shorten the
product life due to excessive wear, and may be dangerous causing damage
and/or personal injury.
AIR SUPPLY
Ensure wrench air valve (or trigger) is in the “off” position before connecting to the
air supply. You will require an air pressure of 90psi, and an air flow according to
specification. Drain the compressor air tank daily. Water in the air line will damage
the wrench. Clean compressor air inlet filter weekly. Recommended hook-up
procedure is shown in fig.1. Line pressure should be increased to compensate for
unusually long air hoses (over 8 meters). The minimum hose diameter should be
¼” I.D. and fittings must have the same inside dimensions. Keep hose away from
heat, oil and sharp edges. Check hose for wear, and make certain that all
connections are secure.
COUPLINGS
Vibration may cause failure if a quick change coupling is connected directly to the
wrench. To overcome this, connect a leader hose to the wrench. A quick change
coupling may then be used to connect the leader hose to the air line recoil hose.
See fig.1 & 2.
WARNING! Ensure you read, understand and
apply safety instructions before use.
Only use impact sockets which are specifically
designed for use with an impact wrench.
Connect the wrench to the air hose as in page 3.
Place the socket over the fastener nut and
depress the trigger to operate the wrench.
To change the direction, push the switch on near
the trigger to the desired direction. (fig.3)
The air flow may be regulated by adjusting the air
regulator dial on the bottom rear of the handle.
DO NOT use any additional force upon the
wrench in order to remove a nut.
DO NOT allow wrench to free run for an extended
period of time as this will reduce bearing life.
WARNING! Disconnect wrench from air supply before
changing accessories, servicing or performing
maintenance. Replace or repair damaged
parts. Use genuine parts only.
Unauthorized parts may be dangerous
and will invalidate the warranty. If the
air system does not have an oiler
lubricate the air wrench daily with a few
drops of air tool oil into the air inlet. Check
and top up the gearbox by removing grub
screw located under the impact head. Clean
the wrench after use.
DO NOT use worn, or damaged sockets.
Loss of power or erratic action maybe due to the
following:
a) Excessive drain on the air line. Moisture or
restriction in the air pipe. Incorrect size or
type of hose connectors. To remedy check the air
supply and follow instructions in chapter 3.
b) Grit or gum deposits in the wrench may also reduce
performance. If your model has an air strainer (located
in the area of the air inlet), remove the strainer and clean
it. Flush the wrench out with gum solvent oil or an equal mixture of SAE
No 10 oil and paraffin. Allow to dry before use.
For a full service, contact your local Sealey service agent.
When not in use, disconnect from air supply, clean wrench and store in a
safe, dry, childproof location.
