5. CARE AND MAINTENANCE
Before working on the tool, ensure that it is not connected to a power source.
5.1. CLEANING
• If the tool is adequately cleaned after use, particularly the mobile parts, this will help to lengthen its useful life.
Remember that dust, sand, environmental conditions – particularly with a high salt index – and dirt in general
are all extremely harmful for hydraulic tooling.
• Particular care needs to be taken when cleaning both the pump drive piston and the compression piston since
any impurities could scratch the cylinder walls and damage the leaktight seals. To clean the pistons correctly, in
this case, we would recommend advancing the piston and then cleaning it with a high quality non-corrosive solvent.
5.2. Power switch
Check that the machine switch is automatically released when you stop pressing it. Should you detect any
anomaly, replace it immediately.
5.3. Brushes
Regularly check the brushes for wear and ensure that they remain in perfect contact with the armature.
Replace the brushes when their length has been reduced by 1/3 of the original length.
Removal:
Remove the carbon brush by first removing the cover and then picking up the carbon brush projection with a flat
screwdriver etc, as shown in the following figure.
Assembly:
To install the carbon brush, select the direction in which the brush toe coincides with the external tube of the
contact part of the carbon brush. Then push the brush with your finger, as shown in the following diagram.
Finally, install the carbon brush cover.
