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 12, 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 8.2 for additional information.
6. Connect cutter to AC power supply. Quickly depress
and release the trigger repeatedly until the piston is
advanced about 3/4 inch [19 mm].
7. Disconnect cutter from AC power supply 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 12,
item 1.
9. Connect cutter to AC power supply and test cutter
for proper operation. Verify that piston automatically
returns to the “home” position after it is fully advanced
and the trigger is releas ed.
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.
11.0 CLEANING THE PISTON AREA
NOTICE:
WARNING
Always disconnect cutter from AC
power supply 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 12:
1. Disconnect cutter from AC power supply 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 counter-
clockwise to manually release the piston. Refer to
Section 8.2 for additional information.
