11.0 CLEANING THE PISTON AREA
NOTICE:
WARNING
Always remove battery from cutter
before cleaning the piston head area or before
manually retracting the piston. Failure to observe
this precaution could result in accidental startup
during cleaning procedures. Serious personal injury
could result.
11.1 Cleaning and Inspection
• Keep the piston area clean to ensure that the piston
fully returns after it advances to maximum stroke.
• Remove any built-up dirt or debris from the cutting
head, the piston and moving blade.
11.2 Manually Retracting the Piston
The piston may fail to fully retract if debris is wedged
under or beside the piston and moving blade.
If this condition occurs, it may be necessary to manually
retract the piston into the cylinder to fully return the
piston to the “home” position.
Refer to the following steps. See Figure 17:
1. Remove battery from cutter to prevent accidental
motor startup during the following steps.
2. Place the cutter horizontally on a stable work surface.
3. Loosen the piston release screw one full turn
counterclockwise to manually release the piston.
Refer to Section 8.3 for additional information.
4. Using a rigid piece of steel bar, manually push the
piston inside the cutter until it is returned to the home
position. See Figure 17, item 3. This should dislodge
any dirt or other material that had prevented the
piston from returning during normal operation.
5. Tighten the piston release screw to enable the
automatic retract function (normal operation). Refer to
Section 8.3 for additional information.
6. Reinstall battery on cutter. Quickly depress and
release the on-off trigger repeatedly until the piston is
advanced about 3/4 inch [19 mm].
7. Remove battery from cutter to prevent accidental
motor startup during cleaning procedures in the
following step.
8. Clean the exposed portion of the piston. Remove any
debris, chips or dirt from this area. See Figure 17,
item 2.
9. Reinstall battery on cutter and test cutter for proper
operation. Verify that piston automatically returns to
the “home” position after it is fully advanced and the
on-off trigger is released.
NOTICE If the piston still does not fully retract after
performing the previously described cleaning procedure,
the cutter should be inspected and serviced by an
Enerpac Authorized Service Center.
