Every 500000 cycles the tool should be completely dismantled and components replaced 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.
Item numbers in bold refer to the general assembly and parts list on page 25 and 26.
Prior to dismantling the tool, you will need to remove the nose equipment.
For total servicing of the tool itself, we advise you proceed with dismantling of sub-assemblies in the order shown below, starting with
either the handle assembly or the manifold assembly, depending on your model.
