Twin-Axis
Sheathing Saw: Safety
Troubleshooting with an Energized Machine
Only a qualified electrician, using the personal protective equipment and following
the procedures recommended in NFPA 70E should ever attempt service or repair
of or near an energized area or component of the machine.
Whenever maintenance is performed while the equipment is electrically
energized, there is a potential electric arc flash hazard. Refer to NFPA 70E for the
personal protective equipment required when working with electrically energized
components. Pneumatic and hydraulic components may move unexpectedly if not
de-energized. Physically restrain any components capable of movement when
working on or near those components.
Safety Tests
This test procedure MUST be performed by qualified personnel at startup and
after ANY maintenance, adjustment, or modification. Testing ensures that the
safety system and machine control system work together to stop the machine
properly.
Inspecting the
Twin-Axis
Sheathing Saw
1. Lockout/tagout the machine.
2. Check the
Twin-Axis
Sheathing Saw for debris or tools that would block
the path of parts. Remove any that you may find. The following locations
are especially important:
• Infeed conveyor and aligner
• Outfeed conveyor and ejectors
• Saw chamber
3. Check the physical condition of the
Twin-Axis
Sheathing Saw. The
following are especially important:
• Both the cross-cut and the rip saw blades should be in the home
position
• The infeed aligner and the outfeed ejector should be in a retracted
position
• The conveyor chain should be on the guide and properly tensioned
• The carriage chains (2) should be on the guides and properly tensioned
4. Remove lockout/tagout and return electrical power and pneumatic
pressure to the machine.
5. Press the blue Reset button. Verify the machine has power by checking if
E-stops are illuminated green.
6. The filter / regulator gauge should match the pressure recommendation
specified in
Maintaining the Filter / Regulator
7. Verify all doors are closed and locked.
