4.1.3.
Drain the air tank daily. Water in the air line will damage the nibbler and will invalidate your warranty.
4.1.4.
Clean air inlet filter weekly. Recommended hook-up procedure is shown in fig.1.
4.1.5.
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.
4.1.6.
Keep hose away from heat, oil and sharp edges. Check hoses for wear, and make certain that all connections are secure.
4.2.
COUPLINGS
4.2.1.
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's 1 & 2.

5. OPERATION
WARNING! Ensure you read, understand and apply safety instructions before use.
‰
5.1.
The nibbler should be set up for use before connecting to the air line.
5.2.
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 re-tighten the locknut (see fig.3-2).
5.3.
Ensure that your workpiece is properly secured and marked out.
5.4.
Connect the nibbler to the air line.
5.5.
Start the nibbler by squeezing the throttle lever.
5.6.
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.
DO NOT allow the nibbler to run freely for any length of time as this will damage
8
the bearings.
6. MAINTENANCE
WARNING! Disconnect the nibbler from the air supply before changing the punch and die, servicing or performing maintenance. Replace
‰
or repair damaged parts.
6.1.
Use genuine parts only. Non-authorised parts may be dangerous and will invalidate the warranty.
6.2.
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.)
6.3.
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 section 4.
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.
6.4.
For a full service contact your local Sealey service agent.
6.5.
When not in use, disconnect from air supply, clean nibbler and store in a safe, dry, childproof location.
6.6.
CHANGING THE PUNCH AND DIE (SEE FIG.3)
6.6.1.
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.
6.6.2.
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.
6.6.3.
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).
