Introduction
READ THE SAFETY CHAPTER BEFORE INSTALLING MACHINE. THOROUGHLY UNDERSTAND
ALL SAFETY ISSUES BEFORE OPERATING MACHINE.
ATTENTION OWNER/BUSINESS MANAGER
To validate the warranty on your new Rottler machine, please
be sure to sign and complete the “Installation Report”
located in the Installation Chapter of this manual.
We suggest that the new user of the VR10 read the CONTROL DEFINITIONS to get an idea how the
machine operates.
The Operating Instructions chapter should be read in order to familiarize the user with the actual button
pushing sequences required to carry out a job. These chapters in the manual should be considered
an introduction. As the operators of the VR10 series machines gain experience with using the di󰀨erent
functions of the machine, complicated setups and programs will make more sense.
The rest of the manual contains information and part number reference on xtures, cutting tools, and
machine maintenance. The operator should read and become familiar with these areas as well.

Installation Procedure
Unpacking and Lifting
Use care when removing the crate materials from the machine. Be careful not to use force on any part of
the machine.
Remove the shipping screws (4) from the skid; the shipping brackets will be painted red and lifting bracket
on yellow for easy identication. These screws are located at the four bottom corners of the Main Base.
The machine can be lifted by ropes once duly secured by.
THIS MACHINE IS TOP-HEAVY. Use care when lifting and moving
Machine
Location
For a suitable working level, suggest to rise the machine up to some 650 mm.
Avoid an excessive smoothness of the oor to prevent any sliding of the operator.
1. Place the machine in its pre-determined location and carefully remove crating.
2. Remove all the shipping brackets painted red, clean the rust preventative with a clean cloth, and
approved solvent.

Section 2 Installation VR10 Manual

3. Remove the shipping bracket from the swivel plate (located on the front of the chuck swivel plate
clamp on the front of the machine).
If you are putting the machine on the bench, make sure to remove the drain tube and install the black
1.00” drain plug located on the back of the machine; be sure the coolant pump is free of all packing.
(Packing material will clog the coolant system)
Machine Bolting
Put it on a bench and duly bolt the machine to it through the holes located on the lower part of the
machine base. Bolt the bench to the oor if decided by using some studs drowned into the concrete by
means of a spirit level; check in both ways the planarity of the machine.

Section 2 Installation VR10 Manual
www.rottlermfg.com
2-8
Power Supply
This machine has the following power requirements:
• 110 to 120 or 208 to 240 VAC
• Single Phase Power
• 50 or 60 Hz
• 20 Amps for 115 VAC or 140 Amps for 220 VAC
See illustration below for correct connection of incoming power. Measured power at the machine’s
main breaker must be within the required range listed above. If incoming power is not within range, a
transformer must be used. Failure to do so will cause the machine to function abnormally and cause
permanent damage to the electronic control system.
Some electrical services contain a “Hot Leg, High Leg, or Wild Leg”, where single phase is derived from a
three phase connection and one leg measures 208VAC to Ground instead of 120VAC. It is not permitted
to use the “Hot Leg” for providing power to this machine. Voltage measured between the phases must be
between 208VAC and 240VAC, while each phase to ground must be ~120VAC.
Electrically connect in accordance with national and local electrical
codes.
Do not attempt to connect more 240VAC to this machine.
Do not attempt to connect to Three Phase Power.

Section 2 Installation VR10 Manual
www.rottlermfg.com
2-9
Grounding
The machine requires a good earth ground. The grounding conductor from the incoming power source
must be connected to the grounding block located inside of the electrical cabinet. A ground rod installed
in addition to the electrical service grounding conductor is permitted, but must be connected directly
to the grounding block inside of the electrical cabinet. Connecting the ground rod to the machine base
is not permitted. Consult a Licensed Electrician in your area to assess the installation, and install the
appropriate ground rod if necessary. Failure to do so may lead to an installation that is unsafe and does
not meet national and local electric codes.
Transformer Connections
This machine has the following minimum transformer size requirement:
• 10 kVA
If a transformer is necessary for machine installation, please refer to the diagram below for connection
information. Transformers must be sized to meet the minimum power requirements listed above. Consult
a Licensed Electrician in your area for transformer selection and installation.
Air Supply
It is very important the air source for the VR10 machine be moisture free.
Water and oil in the line will result in early cylinder and valve failure. The factory recommends installing a
water trap at the machine.
Attach a 100 PSI air source to the intake located on the left side of the machine as you are standing in the
operators position. Adjust pressure regulator so that air pressure going to the machine is between 70 and
90 PSI. ( 4.8 – 6.25 bar )
