MAINTENANCE
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.
If the air system does not have an oiler, lubricate the air nibbler daily with a few drops of the air tool oil, dripped into the air inlet before
use. (To 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 section 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.
