Maintenance; Control Valve Assembly - Avdel 74101 Betriebsanleitung

Maintenance

Every 200000 cycles the tool should be completely dismantled and components replaced where worn, damaged or when recommended.
All 'O' rings and seals should be replaced with new ones 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 not to.
It is recommended that any dismantling operation be carried out in clean conditions.
Prior to dismantling the tool it is necessary to remove the nose assembly. For simple removal instructions see the nose assemblies
section, page 10.
