6. MAINTENANCE
Every 500,000 cycles the tool should be completely dismantled and new components should be used where worn, damaged
or when recommended. All 'O' rings and seals should be renewed and lubricated with Moly Lithium grease EP 3753 before
assembling.
The employer is responsible for ensuring that tool maintenance instructions are given to the appropriate personnel.
The operator should not be involved in maintenance or repair of the tool unless properly trained.
The airline must be disconnected before any servicing or dismantling is attempted, unless specifically instructed otherwise.
It is recommended that any dismantling operation be carried out in clean conditions.
Dismantling of the 07530 MkII and 07532 MkII are covered separately. For the 07530 MkII refer to the dismantling procedures
below and for the 07532 MkII refer to pages 16-18. Item numbers in bold refer to the general assemblies and parts lists
for the respective model on pages 20-23.
Prior to dismantling the tool, you will need to remove the nose equipment.
For total tool servicing we advise that you proceed with the dismantling of sub-assemblies in the order shown below after
having disconnected the hydraulic hose from the intensifier unit and the trigger air line from the intensifier valve, thus
separating the pistol unit from the intensifier unit.
The potentially dangerous substances that could have deposited on the machine as a result of work processes must be
removed before maintenance.
