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 11.
1. Start the pump. Move the piston to the “home”
position (fully retracted). See Figure 7.
2. Stop the pump. Be sure that hydraulic pressure is
completely relieved.
3. Disconnect pump from AC power supply.
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 cutting head. Refer to Section 7.2 for
additional information.
6. Remove retaining ring (Figure 11, item 4). Remove
clevis pin (Figure 11, item 2) and cutting head
(Figure 11, items 5-14).
7. Remove two socket head screws (Figure 11,
item 13), lock nuts (Figure 11, item 6) and front lifting
eye (Figure 11, item 7).
8. Remove two socket head screws (Figure 11, item 12)
and eight socket head screws (Figure 11, item 14).
9. Separate left side outer plate (Figure 11, item 8), inner
plate (Figure 11, item 10) and right side outer plate
(Figure 11, item 11).
10. Remove five fixed blade screws (Figure 11, item 5)
and remove fixed blade (Figure 11, item 9).
11. Install new fixed blade (Figure 11, item 9) onto left
side outer plate (Figure 11, item 8) with five fixed
blade screws (Figure 11, item 5) and torque to
64 ft-lb [87 Nm]. Also apply Loctite 243 or equivalent.
12. Assemble the left side outer plate (Figure 11,
item 8), inner plate (Figure 11, item 10) and right side
outer plate (Figure 11, item 1) using eight socket
head screws (Figure 11, item 14) and two socket
head screws (Figure 11, item 12). Torque to 213 ft-lb
[289 Nm].
13. Install two socket head screws (Figure 11, item 13),
front lifting eye (Figure 11, item 7) and lock nuts
(Figure 11, item 6) and torque to 213 ft-lb [289 Nm].
14. Attach cutting head (Figure 11, items 5-14) to
tool body using clevis pin (Figure 11, item 2) and
retaining ring (Figure 11, item 4).
15. Close the cutting head. Refer to Section 7.2 for
additional information.
16. Test for proper operation before placing the cutter
back into service.
