Introductions / Safety / Installation 2-4 SG9A Manual
www.rottlermfg.com
The SG9A machines have the following areas of exposed moving parts that you must train yourself to respect and
stay away from when they are in motion:
WARNING
Cutting Tool Area – Any operation involving hands in the tool holder, such as inspection or alignment of the tool
holder or tools, changing tool holder or insert holders, tool insertion, and removal, tool holder changes, and size
checking etc. requires the machine to be in neutral or on the off position.
Machining – Eye protection must be worn during all operations of the machine. Hands must be kept completely
away from the cutter head.
Work Loading and Unloading – Carefully develop handling methods of loading and unloading work pieces so that
no injury can result if hoist equipment or lift connection should fail. Periodically check lift components for damage
that may cause failure of Cylinder head Handler Assembly.
Machine Maintenance – Any machine adjustment, maintenance or parts replacement absolutely requires a
complete power disconnection from the machine, this is an absolute rule.
Emergency Procedure:
Assuming one of the following has occurred: tool bit set completely off size, work piece or spindle base not
clamped, spindle is not properly centered, and these mistakes will become obvious the minute the cut starts
PRESS THE EMERGENCY STOP BUTTON (on the front control panel) IMMEDIATELY!
Find out what the problem is; return the spindle to its up position without causing more damage. To restart the
machine, turn the Emergency Stop Button CW until the button pops out. Make sure the button has been depress
for at least 1 ½ minutes or the drive will not have time to reset and they will not function.
Be alert to quickly stop the machine in the event of a serious disruption of the boring process either at the top or
bottom of the bores.
“REMEMBER” metal cutting tools have the speed and torque to severely injure any part of the human body
exposed to them.
Air Supply:
It is very important the air source for the SG9A 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 P.S.I. air source to the appropriate intake in the
small enclosure located on the left rear of the machine near the
bottom.
Bellow you will se the Air regulator panel for the different settings
on the flouting planes on the machine.
And cabinet cooler air regulator.

Introductions / Safety / Installation 2-5 SG9A Manual
www.rottlermfg.com
Air Adjustments:
Float:
The float regulator is located at the rear of the spindle base on the bottom of the interconnect box.
If the machine is not floating properly, it could be from too much or too little air from the regulator. Turn the regulator
all the way off (full counter clockwise).
Start turning the regulator slowly clockwise while continually checking the Work Head for proper floatation. Once
the correct float is established, lock the regulator into place by pushing in on the blue adjusting knob.
: Use as little air as possible to achieve correct floatation. Using too much air will could cause the
spindle base to move slightly to the right when going into tilt. This will cause a scratch up the side of the cylinder.
Power Supply:
This machine has the following power requirements:
208 to 240 VAC it shut not exceed 240 Volts
Single Phase
50 or 60 Hertz
30 amps
See illustration below for correct connection of “measured” incoming power. connect single phase wiring to the
main rear enclosure, located on the right rear of machine base. The connection point for power is located inside the
enclosure. The connection termination point is located on the left hand side of the electrical panel about half way
up. Connect L1 to the grey terminal block, L2 (neutral) to the blue terminal block. Attach wire from the grounding
rod to the second green and yellow terminal.
Important: Electrically connect in accordance with national and local electrical codes.
Grounding:
This machine must be
connected to a good
earth ground rod. A 6
foot, ½” diameter, 15
OHM, Copper
grounding rod driven
into the earth next to the
machines is preferred.
Not providing a
grounding rod could
void factory warranty.

Machine Capacity:
Do not attempt to use the machine beyond its stated capacity or operations. This type use will reduce the
productive life of the machine and could cause the breakage of parts, which could result in personal injury.
Avoid Accidental Starting:
Make certain the main switch is in the OFF position before connecting power to the machine.
Careless Acts:
Give the work you are doing your undivided attention. Looking around, carrying on a conversation and horseplay
are careless acts that can result in serious injury.
Job Completion:
If the operation is complete, the machine should be emptied and the work area cleaned.
Replacement Parts:
Use only Rottler replacement parts and accessories; otherwise, warranty will be null and void.
Misuse:
Do not use the machine for other than its intended use. If used for other purposes, Rottler Manufacturing disclaims
any real or implied warranty and holds itself harmless for any injury or loss that may result from such use.
Placement:
Air supply is connected at the right, rear of the machine, at base of upper casting. Connection can either be a quick
disconnect or permanent threaded connection. Be certain to use an adequately sized air line, permitting proper
operation of float. Air pressure should never drop below 90 PSI at any time. Failure to provide adequate air supply
may cause improper floating and clamping.
At this time, some customers will install a T fitting or manifold at the regulator, allowing another air hose to be
connected, providing a connection point for air tools. The auxiliary hose, if fitted, should be of sufficient length to
easily reach the entire front of the machine.
This machine comes pre-wired and ready to be connected to the power source. The power source should meet all
local and national electrical codes. This service should connect to its own circuit breaker or fuse. In most cases the
machine will require 220 VAC, 15 amp, single-phase service but you should verify voltage requirements by
inspecting the electrical tag located on the rear of the machine.

Machine Installation 4-8 SG9A Manual
www.rottlermfg.com
Chapter 4 Machine Installation
Location:
The productivity of this machine will depend a great deal on it’s proper initial installation, particularly the means by
which cylinder heads are lifted into the machine as well as the material handling to and from other operations in
your shop.
The proper loading arrangement and location for your SG9A machine is extremely important.
A slow travel (6 to 10 feet / min.) power hoist operated from either a bridge crane or a jib crane arrangement works
very well.
Unpacking and Lifting:
Carefully uncrate the machine. Remove all tooling from storage compartments and unpack. Locate the leveling
bolts and leveling pads. Clean all surfaces with solvent and rags to remove protective shipping coatings.
THIS MACHINE IS TOP-HEAVY. Use care when lifting and moving Machine. Approximate shipping
Weight of Machine is 2800 lbs. (1258 kg).
Positioning the Machine:
•Lift Machine using a fork lift. Move fork lift to front of Machine and separate forks so they are visually
centered.
•Insert forks under front-center of Machine, using care not to damage Foot Pedals Valve or Air Lines. Tilt
forks slightly upward so Machine will lean toward fork lift and lift Machine.
•While Machine is on fork lift, install five (6) Leveling Screws and Jam Nuts in holes provided in bottom of
Machine Base. Two (2) Screws installed in rear-corners and one (2) Screw installed in front and rear -
center of Machine Base will serve as Leveling Screws; while two (2) Screws installed in front-corners of
Machine Base will serve only as Support Screws.
•Move Machine to desired location and placed leveling bolts over the center hole of the Leveling Pad. Be
certain to allow sufficient clearance to allow access for leveling and also for connecting air and electrical
lines.
•Lower machine onto leveling pads making certain that the leveling bolts align into counterbore on leveling
pads.
•Be certain nothing interferes with air or electrical lines running from the floating head assembly to the
cabinet.
•Determine there is no possibility of air or electrical lines dragging on wall surfaces or adjacent machinery.
•Wipe top Rails with a clean, dry cloth to remove protective shipping oil.
Do not attempt to move the Work Head unless Air Supply is connected, and air valve is turned on and power has
been turn on (make sure the EMERGENCY STOP Button is off). From the touch screen, float the workhead, spray,
and clean surface with (WD40) or similar degreaser and flow the work Head side by side to remove all the shipping
oil from under the work head. (Top Upper surfaces rails should be clean and free of oil).

Leveling the Machine:
Before leveling the machine, loosen and remove the shipping brackets securing the air float Workhead. (Figures 1
& 2). The air float clamp plate bolts may need to be loosened also. Access to these bolts is gained by tilting the
spindle assembly to the left and loosening the bolts on that side approximately 1 turn. Access to the right side bolts
is obtained by tilting the spindle to the right.
Do not loosen more than necessary to allow the head to float. Clamp assembly will not clamp tight if bolts are
loosened too much. It is best to hold nylock locking nut secure on top side and loosen bolt with wrench from
underside of clamp plate.
Required machinist level. (Starret 98 or better).
NOTE: Rotate Level 180º to check that Level is properly adjusted. If Level does not read same in both directions,
recalibrate level.
Use the level on the upper float surface, level the machine as precisely as possible, front to back and side to side.
Level is obtained fastest when using a three point leveling method.
To utilize a three point leveling method, use only the front outside leveling bolts and the middle bolt in the rear. Use
a socket wrench to turn the leveling bolts. After the machine is leveled, bring in the other leveling bolts. Be certain
all leveling bolts are effectively supporting the machine. Tighten jam nuts on leveling bolts and recheck level.

Sharpener / Vacuum Tester 5-1 SG9A Manual
www.rottlermfg.com
Chapter 5 Mounting Tool Sharpener:
Mount tool sharpener on right hand side of machine using the
cap screw provided with machine.
Rottler Tool Bit Sharpener
When you sharpener the Rottler form Carbide bits, consists in
restoring the tool cutting angle by grinding the face.
To sharp the carbide bit must be fitted on the bit holder also
fitted on the tool holder.
The tool holder will be placed on the adjustable 3/8 fixture of
the tool sharpener.
Slide the tool holder on the fixture, and release the adjusting
knob.
Adjust the fixture to bring the carbide bit flat against the
grinding wheel.
Make sure the carbide tip face is perfectly parallel to the
wheel face by pushing it with the thumb.
Once a good setting is achieved, lock the adjusting knob.
Before to start the grinding motor, move the carbide bit away
from the wheel by rotating the tool holder.
The motor should then be started and the carbide tip face will
just be cleaned.
There is no need to remove a lot of stock from the carbide bit. Sharpening only consists in providing a new cutting
face.
Built In Venturi Vacuum Tester:
Designed to test valve seat and seat surface seal, and particularly to measure the valve seat surface quality after
machining. Including a set of 7 pads and connecting extension to fit must common ports.

Maintenance 6-1 SG9A Manual
www.rottlermfg.com
Chapter 6 Maintenance:
Lubrication:
.Every 40 Hours the outer spindle surface should be cleaned with kerosene or WD40. Occasionally with a
light weight #10 oil. should be wiped onto the outer spindle to prevent excessive dryness.
All floating surfaces should be dry and clean do not oil the surfaces, oil will cause the work heat
not to float properly.
Air Adjustments:
Float:
The float regulator is located at the right rear of the main base on the bottom.
If the machine is not floating properly, it could be from too much or too little air from the regulator. Turn the regulator
all the way off (full counter clockwise). Start turning the regulator slowly clockwise while continually checking the
spindle base for proper floatation. Once the correct float is established, lock the regulator into place by pushing in
on the black adjusting knob.
Use as little air as possible to achieve correct floatation. Using too much air will could cause the
spindle base to vibrate and not center properly on the on the pilot.
Calibrating the Digital Level:
NOTE: Even though the level has been carefully calibrated at the factory,
it is a good idea to recheck calibration before putting the machine into
service. In the event that the level is dropped or handled roughly then the
following recalibration methods should be implemented.
The level assembly is referenced to the spindle via the level pin. It is
there for important to check alignment of pin in reference to the spindle.
This is accomplished by mounting a magnetic base dial indicator to the
machine spindle and sweeping the pin vertically by raising or lowering
spindle to check alignment. Pin alignment should be checked in two
positions at 90 degrees to each other. If the pin alignment needs
correcting, do so with the set screws located at base of pin block.
Install level on pin. Orient level to read left to right. Tilt head left or right
until level reads 0.00. Now rotate level 180 degrees. The reading should
be 0.00, if not then it will be necessary to calibrate the inclinometer to the
level body. This is accomplished by loosening the inclimeter’s two
retaining screws and pivoting the inclimeter until it repeats when level is
rotated 180 degrees.
Example: level reads 0.04 to the left, when rotated 180 degrees to the
right it should read minus 0.04.
Check the level reading with the pickup oriented front to back. It should read 0.00 if the machine has been properly
leveled with a machinist level.
If the LED does not read 0.00 then chances are the machine’s leveling procedures have not been properly followed
or there are internal problems with the level’s electronics.
The sensitivity of the level is so great that it may not zero totally, even while the machine is not being touched. The
alignment tolerance for installing guides is plus or minus .04 degrees, and for forming three angle seats is plus or
minus .08 degrees.

Chapter 7 Operating Instructions:
Mounting Cylinder Heads:
360 Degree Rollover Fixtures
Initial clamp height adjustments to the head trunions can be accomplished by measuring the head thickness then
raising the turning clamping block assembly to the appropriate height using the clamping block acme screws. A
5/16”t-handle allen wrench works well.
Measure the length of the cylinder head. Spread the trunion assemblies apart from each other so that the cylinder
head can be clamped in between the trunions.
Each support has an adjustable stop, located to the front. The stops have indents, allowing a number of different
settings. Position of the stops must be checked for each cylinder head put on the supports. In most cases, we will
install the cylinder head deck side down with the exhaust side of the head against the adjustable stops.
This is particularly true of wedge style heads. It is necessary for the clamps to thrust the cylinder head against the
stops when clamped. When heads are mounted in this fashion, the tallest portion of the combustion chamber will
be at the rear of the machine when the head is rotated into the working position.
Try to keep the valve guide center line parallel to the trunion centerline. (Figure 4)
Utilize the grooves in the table to align the trunion supports square to the machine.
The Quick-Clamp head mounting fixture is provided to accommodate cylinder heads that are difficult to mount
directly into the trunions. Some machine operators prefer to use the Quick-Clamp fixture for the majority of heads
they do as the mounting is very quick.
Utilize the grooves in the table to align the trunion supports square to the machine.

Chapter 8 Overhead Cam U Clamp System
Using 5/15” Allen wrench, remove the existing lower fixed plate on the 360 degree fixture (left and right)
Install the U Clamp, you must use the two bolts included with the fixture and make sure is good and tight
The cylinder head gasket surface must be against the machined surface of the U Clamp Fixture; Slide the stopper
rod equally and push the cylinder heads against the stopper rods.
Note: for some cylinder heads, you make need a spacer against between the cylinder head and the stopper rod
(not included)

The Quick-Clamp frame is mounted between the trunions and clamped using the clamping plates. (See Pictures)
The cylinder head is then held to the frame with the swivel clamp assemblies through the appropriate head bolt
holes or used the standard clamp plates.
