Annually or every 500,000 cycles the tool should be completely dismantled and new
components should be used where worn, damaged or recommended. All 'O' rings and seals
should be renewed and lubricated with Moly Lithium grease EP 3753 before assembling.
For an easy complete service, we are offering a complete service kit.
