Lockout/Tagout
Lockout/Tagout Guidelines
Lockout/tagout all energized systems before performing maintenance on them.
All lockout/tagout guidelines must be met according to OSHA 29 CFR
1910.147. A specific procedure should be included in your company’s energy
control program. This manual is not intended to replace your company’s de-
energizing or lockout/tagout procedure required by OSHA, but merely to provide
general guidance.
The term “lockout,” as used in this manual, means placing a lockout device, such
as a keyed padlock, on any and all energy sources to ensure that the energy
isolating device and the equipment being controlled cannot be re-energized or
operated until the lockout device is removed. The photos on page xiii show where
the electrical disconnects are located for this machine.
• Energy sources include electrical, mechanical, hydraulic, pneumatic,
chemical, thermal, or other energy.
• In the case of electrical energy sources, the main power and control power
to the machinery must be turned off and physically locked in the Off position.
• Before performing maintenance on the pneumatic or hydraulic systems,
bleed the lines prior to lockout/tagout to eliminate pressure.
If more than one person is working in a restricted zone, use a group lockout
device that will allow each person to use a lock that can be removed only by the
person performing the maintenance.
“Tagout” means that a prominent warning is securely fastened to an energy-
isolating device to indicate that the equipment shall not be operated.
Whenever you see this symbol, lockout/tagout!

transmission line to the machine, follow your company’s approved lockout/tagout
procedures which should include, but are not limited to the steps here.
1. Engage an E-stop on the machine.
2. Turn the disconnect switch handle to the Off position. See Figure 1-1.
Figure 1-1: Disconnect Switch in Off Position
3. Attach a lock and tag that meet OSHA requirements for lockout/tagout.
See Figure 1-2.
4. Restrain or de-energize all pneumatic components, hydraulic components,
and other parts that could have live or stored power.
If you are working on the electrical transmission line to the
machine, follow the procedure on page xv.
!WARNING
ELECTROCUTION HAZARD.

Working on a Machine Inside the Machine’s Main Electrical Enclosure or
in the Electrical Transmission Line to the Machine
Before opening the main electrical enclosure, or attempting to repair or
replace an electrical transmission line to the machine, lockout/tagout the
machine properly. Follow your company’s approved lockout/tagout procedures
which should include, but are not limited to the steps here.
1. Engage an E-stop on the
machine.
2. Shut the power to the
machine off at the
machine’s power source
which is usually an electrical
service entry panel on the
facility wall. One example of
a locked-out power source
panel is shown in Figure 1-
3.
3. Attach a lock and tag that
meets OSHA requirements
for lockout/tagout.
4. Open the door to the
enclosure in which you need
access, and using a
multimeter, verify that the
power is off.

Hydraulic or Pneumatic System Lockout/Tagout Procedure
Before working on or near hydraulic or pneumatic components, bleed the lines of
pressure. See Removing Pressure from the Pneumatic System for further
instruction.
When Lockout/Tagout Is Not Required
If working on components other than the hydraulic or pneumatic system, but that
requires you to be near the vicinity of movable hydraulic or pneumatic
components, you must, at a minimum, physically restrain those components from
moving. If this is not possible, lockout/tagout the entire hydraulic or pneumatic
system.
When Lockout/Tagout Is Required
Before attempting repair or performing maintenance on a hydraulic or pneumatic
line or component, lockout/tagout the machine properly. Follow your company’s
approved lockout/tagout procedures.

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 on page 34.
7. Verify all doors are closed and locked.

is depressed:
• the conveyors and the saw blades stop moving
• the active E-stop should blink red
• all other illuminated E-stops should turn solid red
4. Twist the E-stop to release it.
5. Press the blue Reset button.
6. Start operation.
