ABOUT THIS DOCUMENT
SAVE THESE INSTRUCTIONS!
This document contains important safety warnings and
operating instructions for your machine. Before operating this
machine in any way, you and all other operators must read and
understand all instructions. If you don't, there's a risk of voided
warranty, property damage, serious injury, or death.
Keep these instructions with your machine so that they're
readily accessible.
PURPOSE AND SCOPE
This document is intended to provide sufficient information to
allow you to install, configure, and use your machine. It
assumes that you have appropriate experience and/or access
to training for any computer-aided design or manufacturing
software for use with the machine.
GETTING HELP
We provide no-cost technical support through multiple
channels. The quickest way to get the answers you need is
normally in this order:
1. Read this document.
2. Read related documents at tormach.com/support.
3. If you still need answers, gather the following
information so that we may help you as quickly as
possible:
lYour phone number, address, and company name (if
applicable).
lMachine model and serial number, which are located
next to the Main Disconnect switch.
lThe version of PathPilot that you’re running.
lAny accessories that you have for your machine.
lA clear and concise description of the issue.
lAny supporting media and information that you can
share with us. For example, you could:
oAnalyze what might have changed since the
machine last worked correctly.
oRecord a short video.
oTake a picture of a part.
oFor software, share log data .zip files, screen
captures, or program files.
For information, see "Share LogData .zip Files"
(below).
oFrom the PathPilot interface, on the Status tab,
record any available information.
oUse a digital multimeter for voltage readings.
4. Once you've gathered the information in Step 3, contact
us in the following ways:
a. Email: support@tormach.com
b. Phone: (608) 849-8381 (Monday through Friday, 8
a.m. to 5 p.m. U.S. Central Standard Time)
SHARE LOGDATA .ZIP FILES
The controller keeps log data on how the machine has been
working, which you can export as a .zip file. This information
helps us troubleshoot software situations much faster.
To share log data .zip files:
1. Put a USB drive into the PathPilot controller.
2. From the PathPilot controller, on the Status tab, select
Log Data.
PathPilot creates a file called logdata_[TODAY'S-
DATE].zip, and saves it on your USB drive.
3. Remove the USB drive from the controller. Email
support@tormach.com to contact Tormach Technical
Support for guidance on how to proceed.

On the Electrical Cabinet Door
Figure 1-1: Example of a safety decal on the electrical
cabinet door.
1. WARNING! Electrocution Hazard. Points in the electrical
cabinet contain high voltages, which can electrocute or
shock you, causing death or serious injury. Even after the
machine is powered off, electronic devices in the
electrical cabinet can retain dangerous electrical
voltages. Use caution when servicing the machine inside
the electrical cabinet.
2. Lockout/Tagout. Before servicing the machine, you must
power off the machine and use an approved
lockout/tagout device to secure the Main Disconnect
switch in the OFF position. Points in the electrical
cabinet contain high voltages, which can electrocute or
shock you, causing death or serious injury.
Next to the Main Disconnect
Figure 1-2: Example of a safety decal next to the Main
Disconnect.
1. WARNING! Ejection Hazard. Fixtures, tooling,
workpieces, or other loose items can become dangerous
projectiles and can cause death or serious injury. Before
operating this machine in any way, you must verify that
you have appropriately secured all components.
2. WARNING! Loose Workpiece or Workholding Hazard.
You must verify that the workpieces are securely
clamped into the workholding device, and verify that the
workholding device is securely fastened.
3. WARNING! Fire Hazard. The machine and its enclosure
are not designed to contain fire or explosions. Only use
materials and coolants that are intended for the specific
machining operation. Never use flammable or explosive
items. Before operating the machine in any way, you
must read all Safety Data Sheets (SDSs) for any
workpiece materials, coatings, coolants, lubricants, and
other consumables used.
4. WARNING! Inhalation Hazard. The machine and its
enclosure do not protect you from airborne particulates.
Chips, dust, and vapors from certain materials can be
toxic or otherwise harmful. Before operating the
machine in any way, you must read all Safety Data
Sheets (SDSs) for any workpiece materials, coatings,
coolants, lubricants, and other consumables used.
5. WARNING! Cut Hazard. Tools and swarf can cut you.
Only hold tools by the tool holder. Before inserting or
removing tools from the machine, you must verify that
all motion is completely stopped.

6. Don't Use Extended Jaws. You must not use jaws other
than those made specifically for this machine. Extended
jaw can cause the jaws to break or the chuck to fail. If
you use extended jaws, there's a risk of property
damage, serious injury, or death.
7. Don't Wear Gloves. You must not operate this machine
while wearing gloves. If you do, the rotating components
could draw you into the machine while it's powered on
and operating.
8. Personal Protective Equipment:Eyes. Prevent injury by
always wearing protective safety eyewear. Before
operating this machine in any way, you must verify that
your eyewear is impact-resistant and rated for
ANSI787+.
9. Operator Knowledge. Before operating this machine in
any way, you and all other operators must read and
understand all instructions. If you don't, there's a risk of
voided warranty, property damage, serious injury, or
death.
On the Rear of the Headstock
Figure 1-3: Example of safety decals on the rear of the
headstock.
1. WARNING!Bar Whip Hazard. Unsupported bar stock
that extends from the rear of the drawtube can bend
during operation, causing it to whip unpredictably. Never
extend an unsupported bar stock past the left end of the
spindle bore. If you do, there's a risk of serious injury or
death.
2. WARNING! Entanglement / Entrapment Hazard. The
machine operates under automatic control — it can start
at any time and crush, cut, entangle, or pinch body
parts.Always keep clear of positions on the machine
where unexpected or unintended machine motion could
cause harm. Before operating this machine in any way,
you must verify that all operators know the location of
the machine's Emergency Stop button.
1.3.3 Information Decals
Before operating the machine in any way, you must locate and
become familiar with all installed information decals on the
machine and equipment.
Serial Number Plate
The serial number plate is on the side of the electrical cabinet,
near the Main Disconnect switch.
