NOTICE:
WARNING
Always disconnect pump from AC
power supply before beginning cutter blade
replacement procedures. Failure to observe this
precaution could result in accidental startup as
procedures are being performed. Serious personal
injury could result.
4. Place the cutter horizontally on a stable work surface.
5. Open the safety guard. Refer to Section 7.2 for
additional information.
6. Remove the two fixed blade screws (Figure 13, item 1).
7. Remove the worn fixed blade (Figure 13, item 2) and
replace it with the new fixed blade.
8. Install two NEW fixed blade screws (Figure 13, item 1).
New fixed blade screws are included with the new blade.
Torque to 18 ft-lb [25 Nm]. Also apply Loctite 243 or
equivalent.
9. Close the safety guard. Refer to Section 7.2 for
additional information.
10. Test for proper operation before placing the cutter
back into service.
9.5.2 Moving Blade Replacement
Replace the moving blade as described in the following
steps:
1. Start the pump. Extend the piston to allow access to
the moving blade and screws. See Figure 14.
2. Stop the pump. Be sure that hydraulic pressure is
completely relieved.
3. Disconnect pump from AC power supply.
9.5 Blade Replacement
The use of worn blades decreases the effectiveness of
the cutter and can also side load the cylinder, possibly
damaging the tool. Pump overheating may also occur.
Replace blades immediately when it is noticed that
they are worn and/or damaged, or if there has been a
noticeable decrease in cutting performance.
The cutter contains a fixed blade and a moving blade.
Refer to Section 9.5.1 for fixed blade replacement
instructions and to Section 9.5.2 for moving blade
replacement procedures.
NOTICE:
CAUTION
Use extreme caution when removing
and installing blades. Blades may be sharp even
when worn. To avoid hand injury, wear appropriate
hand protection and avoid contact with blade cutting
edges.
NOTICE
To help ensure even blade wear and optimum
cutting performance, it is recommended that both the
fixed blade and the moving blade be replaced at the
same time.
9.5.1 Fixed Blade Replacement
Replace the fixed blade as described in the following
steps. Refer to Figure 13, items 1 and 2.
1. Start the pump. Move the piston to the “home”
position (fully retracted). See Figure 8.
2. Stop the pump. Be sure that hydraulic pressure is
completely relieved.
3. Disconnect pump from AC power supply.
