2. INTRODUCTION & SPECIFICATION
3.1. Air Supply
3.1.1. Remove protective plug from air inlet and connect to the air supply as described below.
3.1.2. You will require an air pressure of 90psi, and an air flow according to the specification above.
3.1.3. WARNING! Ensure the air supply is clean and does not exceed 90psi while operating the nibbler.
Too high an air pressure and unclean air will shorten the product life due to excessive wear, and may
be dangerous causing damage and/or personal injury.
3.1.4. Drain the air tank daily. Water in the air line will damage the nibbler and will invalidate your warranty.
3.1.5. Clean air inlet filter weekly. Recommended hook-up procedure is shown in fig 1.
3.1.6. Line pressure should be increased to compensate for unusually long air hoses (over 8 metres).
The minimum hose diameter should be 1/4” I.D. and fittings must have the same inside dimensions.
3.1.7. Keep hose away from heat, oil and sharp edges. Check hoses for wear, and make certain that all
connections are secure.
3.2. Couplings.
Vibration may cause failure if a quick change coupling is connected directly to the nibbler. To overcome
this, connect a leader hose to the nibbler . A quick change coupling may then be used to connect the
leader hose to the air line recoil hose. See fig 1 & 2.
3. PREPARING NIBBLER FOR USE
Well balanced robust construction with fingertip operated throttle control. Suitable for cutting intricate shapes in
steel up to 1.5mm thick. Punch and die may be rotated through 360° to aid access and obtain maximum
consumable life.

Risk of Hand Arm Vibration Injury.
Air Nibbler model no. SA28.V2 , when operated in accordance with these instructions and tested in accordance with BS EN
28662-1:1993, ISO 8662-1:1988 and BS EN 8662-10:1998 in the following vibration emission declared in accordance with BS
EN12096:1996.
Measured vibration emission value: 4.1 m/s ² Uncertainty: 1.64 m/s ²
These values are suitable for comparison with emission levels of other tools that have been subject to the same test.
This tool may cause hand-arm vibration syndrome if its use is inadequately managed.
Recommended Measures to reduce risk of hand-arm vibration syndrome:
This tool should not be used by an individual regularly for more than 364 minutes in any 8 hour period.
This duration of use should be reduced if the individual is exposed to hand-arm vibration from other sources.

WARNING! Disconnect the nibbler from the air supply before changing the punch and die, servicing or
performing maintenance. Replace or repair damaged parts.
Use genuine parts only. Non-authorised parts may be dangerous and will invalidate the warranty.
5.1. Lubricate the air nibbler daily with a few drops of the air tool oil supplied, dripped into the air inlet
before use. (To re-order air tool oil use Sealey part Nos. ATO/500 or ATO1000.)
5.2. Loss of power or erratic action may be 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 nibbler 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 nibbler out with gum solvent oil or an equal
mixture of SAE No 10 oil and kerosene. Allow to dry
before use. If you continue to experience problems,
contact your local Sealey service agent.
5.3. For a full service contact your local Sealey service agent.
5.4. When not in use, disconnect from air supply, clean nibbler
and store in a safe, dry, childproof location.
5.5 Changing the punch and die. (see fig.3)
5.5.1 Loosen the locknut (see fig.3-2) and unscrew the die (with the locknut on it) from the main body of the
nibbler. Place a 9mm spanner onto the hex section of the die collar as shown in fig.3 and undo and
remove the die collar and punch.
5.5.3 Remove the old punch from the collar and insert the new one. Screw the collar and punch back into
place and tighten with the spanner.
5.5.4 Slide the die and locknut over the punch and screw it back into the main body of the nibbler until the
bottom of the punch is flush with the bottom of the die. Rotate the die into the position required by the
workpiece. Hold the die steady with a 15mm spanner on its flats and retighten the locknut (see fig.3-2).
4. OPERATING INSTRUCTIONS
5. MAINTENANCE
WARNING! Ensure you read, understand and apply safety instructions before use.
4.1 The nibbler should be set up for use before connecting to the air line.
4.2 In order to improve access to the workpiece, the die can be rotated through 360º. To do this, loosen
the locknut with a 22mm spanner (see fig.3-2). Rotate the die (see fig.3-1) on the punch until it is in the
right position for the job in hand. Hold the die steady with a 15mm spanner on its flats and retighten the
locknut (see fig.3-2).
4.3 Ensure that your workpiece is properly secured and marked out.
4.4 Connect the nibbler to the airline.
4.5 Start the nibbler by squeezing the throttle lever.
4.6 Introduce the sheet metal into the slot in the end of the die. Apply light pressure only to move the tool
in the desired direction through the material.
4.7 Do not allow the nibbler to run freely for any length of time as this will damage the bearings.
