“Protective eye and face equipment is required
to be used where there is a reasonable probability of injury that can be prevented by the use of
such equipment.” O.S.H.A. 1910.133(a) Protective
goggles, safety glasses, or a face shield must be
provided by the owner and worn by the operator
of the equipment. Care should be taken to see
that all eye and face safety precautions are followed by the operator. ALWAYS WEAR SAFETY
GLASSES. Everyday glasses only have impact
resistant lenses, they are not safety glasses.
2. Do not disable hood safety interlock system, or in
any way shortcut safety controls and operations.
3. Be sure that wheels are mounted properly, the
hub nut engages the arbor for not less than four
(4) turns, and the hub nut is firmly tightened
before spinning the wheel.

Mounting Wheel on Spindle Shaft
Standard Back Cone Mounting
Use only small or medium cones.
CAUTION
Avoid back injury, seek assistance when
lifting heavy tire/rim assemblies onto the
balancer shaft.
CAUTION
Hubnut must engage threads for at least
four full turns. Failure to tighten hubnut
securely or to force wheel firmly against
the faceplate may result in serious personal
injury.
Select the most appropriate mounting method for
the wheel you are balancing. Using the proper method
ensures secure mounting and safe balancer operation,
and prevents damage to the wheel.
On most wheels, the inner side of the wheel hub usually has the most uniform surface for wheel balancing.
Always center the wheel by the most uniform shaped
side of the hub to achieve the most accurate balance.
Regardless of mounting type, always make sure that
the wheel is forced firmly against the shaft faceplate
and that the hub nut engages the threaded shaft for
at least four complete turns. To assist in centering the
wheel properly, rotate the wheel and the shaft while
tightening the hub nut.
1. Place spring over threaded stud with the large end
inside of the faceplate. Spring must be used.
2. Select a cone that best fits into wheel center hole.
Use only small or medium cones. If a larger cone is
required, use the front cone mounting system.
3. Slide selected cone onto threaded shaft with the
large end against the spring.
4. Lift wheel onto shaft and center on cone.
5. Slide pressure drum onto threaded shaft with the
large end against the spring.
6. Thread hubnut on and tighten with hubnut wrench.
If hubnut won’t tighten all the way down, use the front
cone mounting system. The wheel must be forced
firmly against the faceplate.
7. If you still can’t tighten hubnut because of a lack
of threads, use an additional cone to act as a spacer
between the hubnut and pressure drum.
Figure 17 - Back Cone Mounting
14 • Important: Always read and follow the information box instructions.
Page 21
Standard Front Cone Mounting
Can be used with all cones (do not use spring). This
method works well with most truck wheels where the
bolt circle is less than 275 mm.
1. Select a cone that best fits into wheel center hole.
2. Lift wheel onto threaded shaft.
3. Slide selected cone onto shaft with the small end
against the wheel.
Combi Adapter (Optional)
1. Determine the correct hole pattern by comparing
the rim to the adapter. Wheels with the largest bolt circle (335 mm) should be fastened to the large diameter
side of the reversible adapter - all others should be fastened to the small diameter side (see illustration below).
2. Fasten threaded studs from back of adapter
using the 5/16 Allen wrench. Leave enough threads to
securely fasten hex nuts and lock washers.
4. By lifting wheel from bottom, center on cone.
5. Thread hubnut on and tighten with hubnut wrench.
If hubnut won’t tighten all the way down, remove cone
and wheel. Slide truck cone spacer over faceplate and
repeat steps 2 thru 5. The wheel must be forced firmly
against the faceplate.
6. If you still can’t tighten hubnut because of a lack
of threads, use an additional cone to act as a spacer
between the hubnut and existing cone.
3. Slide lock washers on. Hold the studs in place with
the 5/16 Allen wrench while threading the hex nuts on,
then tighten them down with a 5/16 wrench.
4. Mount the adapter onto the faceplate by inserting
the two (2) drive pins of the adapter into the matching
holes in the faceplate.
5. Slide truck cone onto shaft with the small end
inside the center hole of the adapter. Mount by front
cone method only.
6. Thread hubnut on and tighten with hubnut wrench.
The adapter must be forced firmly against the faceplate.
7. Mount the wheel onto the adapter’s lugs. Fasten
wing nuts by hand then securely tighten them with a
rubber mallet. Wheel must be forced firmly against the
faceplate.
CAUTION
Wing nuts must engage threads for at least
six full turns. Hubnut and cone must force
wheel and adapter firmly against the faceplate. Failure to tighten hubnut or wingnuts securely may result in serious personal
injury.

Match Balance (Optimization)
The Match Balance (Tire/Rim Weight Optimization)
procedure is used to determine the best mating of tire
and rim that will result in the least amount of total unbalance of the assembly. It requires two spins and two
rotations of the tire on the rim. Match Balance may be
needed when:
• The customer complains of ride problems.
Note: A high unbalance may indicate the improper
mounting of the assembly on the balancer, or a rim that
is out of round or malformed, or a tire with a bubble or
other problem. If the unbalance is excessive, it may be
prudent to replace the rim, the tire, or both. If either is
replaced, do not continue with Match Balance. Balance
the new tire and rim and evaluate the readings.
Match Balance Mode
If you choose to use Match Balance to correct for a
condition, such as a large static unbalance, then follow
the information box instructions for the MATCH BALANCE procedure as outlined in the following steps.
Note: Use this procedure only after the wheel has
spun and the corrective weight amount is displayed.
Note: Use the total static display option. See BALANCE OPTIONS, page 11, for further details.
5. Using a tire changer, rotate the tire 180 degrees
on the rim.
6. Remount wheel assembly on the balancer. Press
2 on the control panel; a “3” will appear in the outboard
weight display.
7. Lower the hood and press START. The wheel
spins.
8. When the wheel stops spinning, raise the hood
and rotate the wheel until the valve stem is at top-deadcenter.
9. Press 4 on the control panel.
Weight amounts appear on the control panel. The
amount in the inboard weight display is the weight
imbalance for the rim. The amount in the outboard
weight display is the weight imbalance for the tire. Use
these weight amounts to determine the suitability of
the rim or tire.
Note: If either the rim or the tire weight amount is
close to zero or zero then using Match Balance will not
affect the total unbalance of the assembly.
10. Rotate the wheel until the outboard weight posi-
tion bar flashes. Mark the tire at top-dead-center.
11. Remove wheel assembly from balancer.
1. Press and hold the SHIFT key and press 5 to select
the Match Balance mode. A “1” will appear in the outboard weight display.
2. Raise the hood and rotate the wheel until the valve
stem is at top-dead -center. Mark the tire sidewall at the
valve stem.
3. Press 1 on the control panel; a “2” will appear in
the outboard weight display.
4. Remove the wheel assembly from the balancer.
WARNING
The Match Balance involves the loosening of
tire beads and the inflation of a tire. Training
is necessary in tire changer operation and
understanding the dangers involved during bead seating and tire inflation before
attempting this stage of the Match Balance
procedure. Read the operators manual supplied with the tire changer and consult a
supervisor.

Calibration
Machine Calibration
Important: Use the correct calibration weight amount:
a 4-ounce calibration weight in ounce mode.
Important: The factory default is set for a 4-ounce
calibration weight amount for both ounce and gram
weight measurement modes. Therefore only a 4-ounce
calibration weight is necessary, regardless of weight
measurement mode setting.
Important: Before beginning calibration, be sure the
balancer is in fine balance mode by pressing the SHIFT
key and 6 to toggle to 0.01 oz. display mode; and balance the tire down below 0.20 oz.
1. It is necessary to machine calibrate at least once in
both Truck and Car modes. Start calibration as follows:
Truck Mode - Hold SHIFT key and press 4 until
both Car Mode and Light Truck LEDs are toggled
off (both lights OFF IS Truck Mode). Then, mount a
R11 22.5 steer tire/wheel assembly on the balancer.
Note: Once both Truck and Car modes are initially cali-
brated, then it is only necessary to calibrate in the mode
that requires calibration. For example, if only truck tires
are balanced on this machine, then only the machine
calibration in Truck Mode is required.
Important: A balanced tire/wheel assembly is required.
Note: Position wheel so that no weights are on
either flange at the top-dead-center location. Turn the
machine OFF then ON.
2. Hold SHIFT key and press 1 to select the CAL
MACHINE mode.
3. Enter the D dimension.
4. Lower the hood and press START.
5. After spin, raise the hood. Attach calibration
weight to the outside flange at top-dead-center.
6. Lower the hood and press START.
Important: It is critical that the inner weight be
placed accurately to achieve proper calibration. If the
calibration weight is not moved from the outside flange
directly across to the inside flange, an inner weight
placement error will occur. To correct, follow the information box instructions.
7. After spin, raise the hood. Move and attach the cal-
ibration weight to the inside flange at top-dead-center.
Figure 21 - Calibration Weight Moved (Directly Across) To
Inside Flange
8. Lower the hood and press START.
9. Calibration complete. Press NEXT.
10. After completing the Machine Calibration proce-
dure, the Arm Calibration will automatically initiate.
Arm Calibration
The Arm Calibration procedure begins immediately
after Machine Calibration.
During Machine Calibration, the balancer software
calculates both the A and W dimensions. The Arm Calibration gives the balancer software a reference point
to the edge of the faceplate and home position. When
the user enters the A dimension from the arm rod, it
calculates the difference from the machine calibration
A and uses that as a factor for the manual A entry. Arm
calibration also gives the D dimension a reference point
from home position.
11. Bring the tip edge of the arm precisely to the
outer edge of the faceplate and hold it there while
pressing the NEXT key. (If necessary to reach the
faceplate accurately, loosen the calibration wheel temporarily.)
Figure 20 - Calibration Weight On Outside Flange At Top-DeadCenter
Important: Always read and follow the information box instructions. • 17
Page 24
12. With the arm still at the edge of the faceplate,
enter the A dimension shown on the arm rod. Press the
NEXT key.
Figure 22 - While Holding Arm at Faceplate Edge, Enter A
13. Move the arm to its home position and press the
NEXT key.
14 . Move the arm to the clip-on weight location on
the rim flange and hold it there while manually entering
the D dimension. Press the NEXT key.
Maintenance Instructions
The balancer requires only minor maintenance to keep
the unit operating properly.
1. Keep the display clean and clear. Use a damp cloth.
Do not use cleaners or solvents which leave oily or filmy
residues behind.
2. Keep the adapters, cones, faceplate, threaded
shaft, pressure cup, and hub nut clean. Grease and dirt
buildup will cause inaccurate balancing and premature
wear. Clean these items at least once a day with a
vaporizing solvent.
3. Clean weight tray and any accessory posts, pegs,
or storage shelves with a vaporizing solvent. Weights
stored in a dirty tray may pick up grease and dirt which
may keep them from securely attaching to the wheel.
WARNING
Use common sense, this is an electrical
device. Exposing the balancer to water,
either by hose or bucket, or by exposure
to rain or snow, may cause risk of shock
or electrocution to operator or bystanders.
Place, store, and operate the balancer only
in a dry, sheltered location.
15. While still holding the arm at the clip-on weight
position on the wheel, enter the dimension read off the
arm rod. Press the NEX T key.
16. Return the arm to home position; arm calibration
is complete.
Important: To redo the Arm Calibration procedure,
press and hold SHIFT and press 0, then press 19 to
bypass the Machine Calibration requirement. Always
use the same wheel assembly that was used during
the machine calibration or else the calibration will not
be correct.
17. If machine calibration for the Car Mode/Lt. Truck
Mode is necessary then:
Car Mode - Hold SHIFT key and press 4 until Car
Mode LED is toggled on. Then, mount a 16-inch
steel tire/wheel assembly on the balancer and
repeat steps 2 through 16.
Note: Car Mode calibration covers both Car mode and
Light Truck mode.
Important: A balanced tire/wheel assembly is required.
Note: Position wheel so that no weights are on
either flange at the top-dead-center location. Turn the
machine OFF then ON.
CAUTION
Do not hose down with water or bucket
wash the balancer. Extensive damage to
the balancer will result. Sensitive electronic
components, wiring harnesses, and other
devices housed in the balancer are not
intended to be exposed to water.
4. Keep the area around and under the balancer
clear. Remove any tools or other items that are leaning
against the balancer. Remove any items that may cause
the balancer to not sit level. Be particularly cautious of
new or used wheel weights on the floor, as they may
cause personal injury due to falls.
5. Use only COATS® accessories. Accessories from
other manufacturers may not fit or function properly,
and may damage the balancer.
6. To replace Arm Laser battery, remove cover
(fig. 23). Discard
old battery. Install
a new battery and
replace the cover.

Diagnostic Procedures
After Balance Vibration Problems
If vibration is still present after balancing the wheels
and driving the vehicle on smooth pavement, remove
the wheels and recheck the balance. If a wheel is out
of balance the cause maybe:
• Wheel was not mounted/centered correctly on the
balancer.
• A weight has come off the wheel (possibly the
wrong clip style). Remove the other weights from
the wheel and rebalance.
• Foreign material inside the tire. Remove the tire
from the wheel, remove the foreign material, and
remount. Remove wheel weights and rebalance the
wheel.
• Stones or other foreign objects caught in the tire
tread or rim. Remove the objects. Check and rebalance if needed.
If the balancer still indicates the wheels are balanced
to within 0.01 ounces on both inner and outer displays,
the problem is not in the balance of the wheels. Check
the following possible sources of vibration:
• Tire pressure. Bring all tires up to the recommended
PSI.
• Radial or lateral runout in the tire or wheel. Replace
the damaged part.
• Unbalance in wheel covers or trim rings. Remove
the wheel covers or trim rings and test drive. If
the vibration is gone, remove the shaft and use
an appropriate adapter to mount the wheel to the
balancer. Balance the wheel with the wheel cover
or trim ring attached to the wheel.
• Incorrectly mounted tire and wheel. Remount correctly.
• Damaged wheel bolt holes. Replace wheel.
• Worn universal joints. Replace as required.
• Drive shaft unbalance or damaged. Balance, repair,
or replace.
• Unbalance in brake rotor(s) or drum(s).
• Suspension out of alignment. Align the vehicle and
replace any damaged or worn parts.
