Solution
Be sure reservoir is filled with Enerpac oil.
Be sure all coupler connections are complete. Loose
or incomplete coupler connections will cause complete
or partial blockage of oil flow.
Remove blade screw from piston to release pressure.
Remove cutter head latch pin or spring latch to free
blade.
Clean the blade and blade track. Hone the blade. See
Maintenance step 6 on page 4. Lubricate the blade
and track with silicone spray.
See illustration below. Place wooden wedge against
the release pin and lightly strike wedge with a
hammer. The lever should release forward to by-pass
and relieve pressure.
The blade should retract. If debris is caught between
the blade and cutter head, disassemble and clean as
described above.
Replace seals. Seals are available as part of the
Repair Kit for your cutter. An Authorized Enerpac
Service Center can perform the repairs for you.
