Care And Maintenance - haupa AH-12 Instruction Manual

5. Care and maintenance

Cleaning
• Careful cleaning of the tool, in particular, the moving parts contributes towards a longer
useful life. Remember that dust, sand, environmental influences, in particular a high salt
index, and dirt in general are extremely damaging to hydraulic tools.
• Particular care should be taken when cleaning the pump drive piston and the piston.
The tiniest of contaminations may scratch the walls of the cylinder and damage the
leak-proof seals. For correct cleaning of the piston, we recommend extending the piston
and then cleaning it with a high-quality, non-corrosive solution.
Power switch
Check to see whether the switch on the machine automatically pops out again when you release
it.
Filling level of the oil tank
Ensure that the oil level is always sufficient. Do not fill the tank with unsuitable oil or brake fluid.
Oil type: VESTA HLP-15 from VERKOL or an oil of a similar quality. Remove the tank lid and top up
the oil. The oil must be filtered first. If necessary, purchase the required oil from the HAUPA service
centre (Art. 216254).
Storage
To prevent damage to the tool as a result of bumps, dust etc. you should if possible store the
tools in the original packaging.
Oil level
The oil level in the tank should be checked at regular intervals, in particular, when it has been
used for a long time and topped up whenever necessary.
Oil filling
This process should only be carried out by an authorised technician.
Important: The hydraulic oil must be filtered, have an ISO viscosity class of 15 and a viscosity
index of 100 and correspond to the standards AFNOR NFE 48603-HM and
ISO 6743/4 L-HM.
WARNING NOTES!
A natural working position is required in order to operate the tool correctly, thus the handle must
point downwards.
