ATTENTION!
The TC289 Tire Changer now has an improved turntable size. Please
read the information below.
Due to our continuous efforts to improve our products’ features and performance, the
published specifications of these products are sometimes updated to maintain accuracy.
Your TC289 Tire Changer has a new, larger sized turntable. The clamping ranges that are
listed on pages 8 and 15 in the TC289 Installation and Service Manual have been
changed to show this improvement. The new turntable clamping ranges are listed below:
External Clamping Range
Position 1) 11 7/8" - 26"
Position 2) 12 7/8" - 27"
Position 3) 13 3/4" - 28"
Internal Clamping Range
Position 1) 13 7/8" - 27 7/8"
Position 2) 14 5/8" - 28 7/8"
Position 3) 15 5/8" - 29 7/8"
External Locking Rim Dimension
(With Flip Adapters in the ATV Configuration)
Position 1) 4 7/8" - 19"
Position 2) 5 3/4" - 20"
Position 3) 6 3/4" - 20 7/8"
External Locking Rim Dimension
(With Flip Adapters in the Motorcycle Configuration)
Position 1) 15" - 29 1/8"
Position 2) 15 7/8" - 30"
Position 3) 16 7/8" - 31"
Note: The ranges listed above are actual measurements in inches. These do not indicate
specific wheel sizes. Most vehicle wheels are larger than their nominal size. For example,
a 16” wheel may be up to 17.5” in actual diameter.
Because of variances in wheel designs, a specific clamping range measurement does not
guarantee that a particular wheel size can always be clamped into place.

the push-lock fittings as
far as possible.

Step 3: Turntable connections
Press the air lines into the
push-lock fittings as far as
possible.
Step 4: Inflator box connection
Press the air line as
far into the push-lock
fitting as possible.

4.3 COMMISSIONING
Any electric connection job must be carried out by professionally qualified
personnel.
Make sure that the power supply is right.
Make sure the connection of the phases is right. Improper electrical hook-up
can damage motor and will not be covered under warranty.
xCheck to make sure the characteristics of your systems correspond to those required by the
machine. If you have to change the machine’s operating voltage, make the necessary
adjustments to the terminal board referring to the electric diagram in chapter 9.
xConnect the machine to the compressed air system by means of the air connection (Q) that
protrudes from the rear section.
Connect the machine to the electric network, which must be provided with lin
e
fuses, a good earth plate in compliance with regulations in force and it must b
e
connected to an automatic circuit breaker (differential) set at 30 mA.
Should the tire-changer be lacking in electric plug, the user must set one, which
is at least 16 A and which conforms to the voltage of the machine, in compliance
with the regulations in force.
4.4 OPERATING TESTS
xWhen pedal (Z) is pressed down the turntable (Y) should turn in a clockwise direction. When
pedal is pulled up the turntable should turn in an anticlockwise direction.
If the turntable turns in the opposite direction to that shown, reverse two of the
wires in the tree-phase plug.
xPressing the pedal (U) activates the bead
breaker (R); when the pedal is released the
bead breaker returns to its original position.
xPressing the pedal (V) opens the four clamps
(G); when the pedal is pressed again they
close.
xPressing the trigger on the airline gauge cause
air to be released from the head.

REV. 01 15 / 27
4.4.1 GT version
Do NOT LEAN on the turntable during this operation. Possibly dirty dust on
turntable could offend the operator’s eyes. For the same reason, be carefully as
not to accidentally push the inflating pedal while working.
xWhen the pedal located on the left side of the machine
body is pushed down to its intermediate position (B),
air is released from the airline gauge.
xWhen the pedal (C) is pushed down completely, air is
released from the airline gauge with a powerful jet from
the nozzles located on the turntable clamps.
4.5 TURNTABLE LOCKING VALUE ADJUSTING
The tire changer turntable is preset by the manufacturer on a middle range measure from11” to 23”
ext. (considering the rim outer side and) from 13” – 25” int. (if you lock the rim from inner side).
It is however possible to change this dimension range in case of need when working on larger or
small rims; it is enough to change the position of the 4 clamps are shown in the figures below.
The obtainable value starts from a minimum of 10”-22” ext. and 12”-24” int. until a maximum of 12”-
24” ext. and 14”-26” int.
To change the position, proceed as follows:
xUnscrew screw (1) by means of the Allen wrench.
xRemove the locking clamp (2) and the slide piece (3).
xAlign the slide hole with one of the guide holes (4) according to the locking dimensions you
want to set. Use the measures below for reference.
It is important to perform the above mentioned operation for all the 4 clamps to
avoid any unbalance in locking phase.

CHAPTER 5 – OPERATION
Do not use the machine until you have read and understood the entire manual
and the warning provided.
Before carrying out any operation, deflate the tire and take off all the wheel
balancing weights.
The operation of the tire changer is divided into three parts:
a) BREAKING THE BEAD b) REMOVING THE TIRE c) MOUNTING THE TIRE
It is advised to equip the tire changer with the pressure regulator.
5.1 BREAKING THE BEAD
Bead breaking must be done with the utmost care and attention. When the bead
breaker pedal is operated the bead breaker arm moves quickly and powerfully.
Anything within its arrange of action can be in danger of being crushed.
xCheck that the tire is deflated. If not, deflate it.
xClose the turntable clamps completely.
Bead breaking with the clamps in open position can be extremely dangerous for
operator’s hands.
During bead breaking operations NEVER touch the side of the tire.
xPosition the wheel against the rubber stops on the right side of the tire changer (S).
xPosition the bead breaker (R) against the tire bead at a distance of about 1 cm from the rim (fig.
8). Pay attention to the blade, which must operate correctly onto the tire and not onto the rim.
xPress down the pedal (U) to activate the bead breaker and release it when the blade has reached
the end of its travel or in any case when the bead is broken.
xRotate the tire slightly and repeat the operation around the entire circumference if the rim and
from both sides until the bead is completely detached from the rim.
