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 VR9 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 VR9 series machines gain experience with using the different
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.

Description
The VR9 machine is designed for resurfacing by grinding wheel of engine valves.
Rottler VR9 valve grinding machine can grind valves from 15 to 60 degree. Variable valve rotation speed
allow the operator to control surface speed for different diameter valves. Solid cast-iron construction
dampens harmonic vibration to eliminate chatter. Valves are held by a precision chuck system with
pneumatic operated quick action. A large capacity cooling removable tank holds 5 gallons / 20 liter of
grinding uid.
Each Rottler Chuck offers a dual system of three hardened steel balls - one towards the front of the
Chuck and another system in the back of the Chuck holding the valve in the portion of that will be running
in the Guide to the valve stem.
This automatically aligns the stem of valve, allowing that the face of the valve to be concentric to the
valve, stem depending on the conditions of the stem.
The Rottler linear Centered system ensures accurate in relation to the stem, alignment based on account
that we are working with a valve in which the stem is between the tolerances for wear, so we could ensure
that the valve seat this concentric ground.

ROTTLER VR9 INSTALLATION REPORT
ROTTLER MANUFACTURING MUST HAVE THIS REPORT RETURNED TO
PROPERLY QUALIFY WARRANTY ON EQUIPMENT
Customer:__________________________________ Address:_______________________________________
City:__________________________________ State:_____ Zip:____________ Phone:________________
Machine Model:______________ Serial Number:___________ Representative:________________________
MACHINE INSTALLATION: Electrical information MUST be complete to validate this report.
Customer is responsible for providing electricity to machine in a manner that meets the local electrical code
requirements.
______Check machine with precision level and for equal support on feet.
______This machine requires 208 to 240V AC 1-phase, 50/60HZ, isolated power supply (measured between L1
and L2). Current requirement is 15 amps. When using two legs of a three-phase supply, the voltage
from each leg to ground must be between 100-120V AC. Measure the voltages of the power supply twice
during installation (1) _______VAC (2) ________VAC.
______Measure each leg of the incoming supply to ground. When using a one leg and neutral of a 380 VAC three
phase supply L1 should measure 240 VAC and Neutral should measure almost 0 VAC.
L1 to ground __________VAC L2 to ground __________VAC.
Make sure all electrical equipment has the proper overload protection. The VR9 should have a fully isolated power
supply to prevent damage and uncontrolled movement of the machine. If the VR9 is on the same power lines that
are running to other electrical equipment (grinders, welders, and other AC motors) electrical noise can be inducted
into the VR9 electrical system. Electrical noise can cause the controller to see false signals to move.
Neutral and machine ground are not the same thing. You should measure an open
circuit between Neutral and ground.
IF VOLTAGE IS OUTSIDE THE CORRECT RANGE AT ANY TIME THE MACHINE
WILL NOT OPERATE PROPERLY AND MAY BE DAMAGED.
______BEFORE turning power on to the machine. Check all wires for security by using the correct screw driver
and turning CW until movement stops. Stranded wire can “spread” slightly from vibration during transport.
______Air of the proper pressure and capacity connected to the machine below 70 to 90 PSI Air supply must be
free from oil and water. Oil or water will damage electrical and air components. Air pressure should never
drop below 70 PSI at any time. Failure to provide adequate air supply may cause improper clamping.

______Remove back cover from the Control Panel and recheck/Inspect all wire connections with a screwdriver for
security, Stranded wire used in these machines can spread and loosen a connection when shipping.
______Remove the shipping bolts and brackets.
______Clean any rust inhibitor from the machine surfaces.
______Conrm that coolant pump is wired and plumbed. See Installation section of manual for detailed
instructions if needed.
______Have the operator read through the operation manual before training begins. This will help him be familiar
with the button pushing sequences. Have the operator read through the manual again after training and
some of the sequences will make more sense.
MACHINE START-UP
When starting the machine for the rst time, it may move out of control. Make sure all
hands are clear of machine parts. Be ready to press the Emergency Stop button if
needed.
______Turn main power on from the main incoming breaker box.
MACHINE MOVEMENTS
