CLEANING & OVERHAUL

1. If the wrench becomes sluggish and the air supply is of good quality, it may 

be necessary to replace worn or damaged parts.

2. Grit or gum deposits in the 

mechanism may eventually 
reduce efficiency. This condition 
can be corrected by cleaning the 
air inlet filter and flushing out the 
tool with gum solvent oil or an 
equal mixture of SAE No10 oil and 
paraffin.

3. Failing this, the tool may be 

dismantled by unfastening the 
bolts and removing the rear cover 
prior to replacing any worn or damaged parts. You may prefer to take the 
tool to your Clarke dealer if internal maintenance is required.

4. While is a dismantled state, it may be desirable to grease the hammer 

mechanism and applying a small amount of good quality bearing grease.

• This may be better left to your Clarke dealer.

STORAGE

If the tool is to be stored or is idle for longer than 24 hours, run a few drops of 
Clarke air-line oil into the air inlet and depress the trigger in order to lubricate 
the internal parts.

When not in use, the tool should be disconnected from the air supply and 
stored in a dry place out of the reach of children. Avoid storing in a damp 
environment.
