overheating.
Connect the control unit to the milling machine via the dedicated cable.
Connect your milling machine to the power supply with the cable supplied to a
suitable socket and check the status of the power supply cable. A single, direct
connection is preferable to accumulating with other plugs.
Do not use the machine in a dangerous environment, as it is an electrically-
powered system. It must be connected to the mains power supply or an electrical
generator. It runs on 220 volts. Do not use in damp places or places exposed
to rain.
Do not use or leave electrical tools near flammable liquids or in gaseous or
explosive atmospheres. The motors may generate sparks and catch fire.
When changing accessories, only use those tools that we have supplied for this
purpose.
Do not force tools or accessories if they do not work properly, as it is certain
that there is a problem. Check out what could be causing this.
It is prohibited to disassemble and/or modify your digital milling machine. Any
part that has been disassembled or modified will no longer be covered by the
manufacturer’s warranty, unless the latter expressly agrees to such.
When changing milling cutters and before using again, check that you have
removed any tool, spanner or similar items from the machine and its area of
use.
Before starting up the Oakbot, check that any object in the machining zone is
removed that might come into collision with the milling cutter and possibly
injure the operator, disrupt your machine or even seriously damage it.
Place your milling machine on stable wooden blocks that can take its weight.
Vibrations from the milling machine may unbalance any inadequate support and
cause the unit to fall over, which may result in serious injuries and damage
to machine and environment, and possibly cause fires.
Use the clamping system as recommended in this manual and do not use in any
other way. Poor clamping may lead to the machine falling over, causing serious
injuries and damage to the system and its environment.

epur | USER’S MANUAL

The machine must be kept under supervision during the first few seconds of the
milling process. If clamping is not properly ensured, this often leads to
uncoupling at the beginning of the machining process.
Wait for the machine and the spindle to stop completely before handling
workpieces or the machine.
The OAKBOT which comes with its clamping system and handling trolley is a unit.
No machining must be carried out or movement made without the robot being
engaged on the clamping system and suspended on its trolley.

General Recommendations
General
Your OAKBOT is a portable cutting robot for structural timber assemblies and joints
of all sorts, including tenons, mortises, dovetail joints... positioning itself at
the ends and edges of a beam. Using the OAKBOT will require a trolley for handling
the robot as well as a clamp between the robot and the workpiece to be machined.
Implementing this stage properly, as described below, is essential for ensuring
your own safety and achieving the smooth unit operation. Once clamping is carried
out, machining configuration is easy using your remote control which features a
touch-control interface to guide you throughout the process. Machining will then
be automatic and require no personal intervention during the assembly.
Handling
For your own safety, wearing safety footwear is mandatory when handling your
robot. If the robot falls over during handling, this may result in serious
injury to the operator.
Avoid placing the unit on the ground, so as not to have to lift it into the
suspension position. We recommend using the handling trolley which enables you
to place your machine at the correct handling height at any time. At all times
during machining cycles, the machine must be suspended from the handling trolley.
If you have to lift your milling machine cutter from the ground, use correct
postures and gestures. The same goes when transporting your machine.

epur | USER’S MANUAL
www.epur.io - - | 13 | - - contac[email protected]o
ADOPT CORRECT POSTURES
CARRYING
Environment
To work in complete safety, your work environment must be adapted to OAKBOT use.
Your OAKBOT is a robot: when being used, some parts are fixed, while others are
mobile and will enter into movement:
As a result, its centre of gravity may change during use. Consequently, you
must check permanently that instructions for use of the mobile trolley are
respected (particularly with cants and slopes) – see the OAKBOT handling trolley
user’s manual.
When being moved, your robot will also assume variable dimensions. Consequently,
you must check that the robot’s moving part is totally free to move and that
the environment around your support is sufficiently uncluttered to avoid any
risk of collision and any risk of the operator being crushed throughout the
whole of the robot’s travel. Keep the workspace clean and uncluttered, as
congested places contribute to accidents.
/!\ CAUTION /!\
Taking all possible positions of the robot into consideration, the OAKBOT’s maximum
width is 1400 mm.

epur | USER’S MANUAL
www.epur.io - - | 14 | - - contac[email protected]o
Test Conditions
In order to use your OAKBOT in the best safety conditions, respect the following
rules:
Only mill wood.
Only use milling tools supplied by EPUR.
Check that no foreign body other than wood be present in the part to be machined.
Always place the beam to be machined with its largest width in a sectional
position, parallel to the jaws of the clamping module.
Ensure that whenever the robot is operating (simply moving or during a machining
cycle):
The robot is suspended from its handling trolley
The robot is snapped into place and locked onto the clamping system
The devices for confining off the machining zone are deployed.
/!\ CAUTION /!\
The user is fully responsible for checking that no operation is requested to be
carried out by the OAKBOT if the latter is not snapped into place and locked
properly in its clamping system with the devices for confining off the machining
zone deployed. The OAKBOT must also be suspended correctly from its handling trolley.
Failure to respect this rule of use shall release the EPUR SAS Company from any
liability whatsoever.
/!\ CAUTION /!\
The user shall be fully responsible for positioning the OAKBOT on the workpiece to
be machined. In the event of the device tipping over, falling or colliding as a
result of the OAKBOT being used, the EPUR SAS Company shall not be held liable in
any way whatsoever.

epur | USER’S MANUAL
www.epur.io - - | 15 | - - contac[email protected]o
Warning about dimensioning assemblies
/!\ CAUTION/!\
Although a digital tool, the OAKBOT is only a milling cutter and, as such, it is
up to the user to calculate machining dimensions. In no way can EPUR guarantee the
dimensioning of assemblies or joints carried out using the OAKBOT, for any assembly
whatsoever. Consequently, the EPUR SAS Company shall not be held liable for any
damages or financial losses caused by faulty assemblies.
Safety
Machine status indicator light
Lights indicating machine status (green and red) are located on the robot’s
electrical control unit.
If the green light is on, the machine is ready to be configured.
If the red light is on, the robot is machining or moving (even if the user
cannot perceive any movement) and the operator must stand aside in the zone
situated at the rear of the robot and respect a minimum distance of 1 metre
between him/her and the machine.

epur | USER’S MANUAL
www.epur.io - - | 16 | - - contac[email protected]o
/!\ CAUTION /!\
Before initiating any action, check that no one is present in the side areas of
the machine, regardless of the distance. Also check that no one is present in the
front zone, less than 3 metres away from the machine.
If the red light is flashing, this is because the machine has placed itself in
safety status (motor power supplies cut off), which may happen in 2 cases:
The emergency stop button has been actuated.
The machine has detected an obstacle in its path.
Whatever the case, the procedure to be followed will be indicated on the screen.
Device prohibiting access to the machining zone
In order to prevent any risk to the user, the device confining off the machining
zone must be deployed for any action requested of the machine. This device prohibits
