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.
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, air lines from the intensifier and control box, 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.
