use of other operators, properly trained and with suitable clothes.
THE CAREFUL LUBRICATION OF THE TIRES
BEADS IS RECOMMENDED, IN ORDER TO PRO-
TECT THEM FROM POSSIBLE DAMAGES AND
TO FACILITATE MOUNTING AND DEMOUNTING
OPERATIONS.
11.3 Preparing the wheel

• Findtherimlockingtype.
WHEN HANDLING WHEELS WEIGHING MORE
THAN 500 KG (1102.5 LBS) A FORK-LIFT TRUCK
OR A CRANE SHOULD BE USED.
11.4 Wheel clamping
DUE TO THE SIZE AND WEIGHT OF THE WHEEL/
TIRE, MAKE USE OF A SECOND OPERATOR TO
HOLD THE WHEEL INTO VERTICAL POSITION,
IN ORDER TO ENSURE SAFE OPERATIVE CON-
DITIONS.
MAKE SURE THAT RIM CLAMPING IS DONE
PROPERLY AND THAT THE GRIP IS SECURE, TO
PREVENT THE WHEEL FROM FALLING DURING
MOUNTING OR REMOVAL OPERATIONS.
DO NOT CHANGE THE SET OPERATING PRES-
SURE VALUE BY MEANS OF THE MAXIMUM
PRESSURE VALVES. THE MANUFACTURER
SHALL NOT BE RESPONSIBLE FOR INJURY
OR DAMAGE ARISING FROM UNAUTHORISED
CHANGES.

THE OPENING/CLOSING MOVEMENT OF THE
SELF CENTERING CHUCK GENERATES A GREAT
DEAL OF COMPRESSIVE FORCE DURING THE
WHEEL LOCKING/UNLOCKING PHASE. KEEP
HANDS/FINGERS OR ANY PART OF THE BODY
AWAY FROM MOVING CLAMPS AT ALL TIMES.
All wheels must be clamped from the inside.
CLAMPING ON THE CENTRAL FLANGE IS AL-
WAYS SAFEST.
FOR WHEELS WITH DROP CENTER RIMS SE-
CURE THE WHEEL SO THAT THE DROP CENTER
IS FACING OUTWARDS COMPARED TO THE
SELF-CENTERING CHUCK.
IF IT IS NOT POSSIBLE TO CLAMP THE RIM IN
THE HOLE OF THE DISC, CLAMP ON THE BEAD
SEAT CLOSE TO THE DISC.
TO SECURE WHEELS WITH ALLOY RIMS AD-
DITIONAL PROTECTIVE JAWS ARE AVAILABLE.
THEY ALLOW YOU TO WORK ON THE RIMS
WITHOUT DAMAGING THEM. THE PROTECTIVE
JAWS ARE FITTED ONTO SELF-CENTERING
CHUCK NORMAL JAWS BY MEANS OF A BAYO-
NET CONNECTION.
To clamp the wheel proceed as follows:
- make sure the front bead breaker arm is in open position (Fig._16
ref._2);
- place the wheel in vertical position onto the platform;
- move the wheel close, by keeping it in vertical position, until graz-
ing self-centering chuck jaws;
- use the corresponding control (Fig._13 ref._G-H) to position the
coaxialself-centeringchuckwiththewheelcenter,inorderto
make jaws edges skim wheel edge;
- adjust the opening of the self-centering chuck through the cor-
responding control (Fig._13 ref._M-N) according to the type of rim
to be locked;
-tiltthewheelatapproximately15°towardstheself-centeringunit;
- operate the control (Fig._13 ref._M) until the wheel is completely
clamped;
- check both that the rim is clamped and centered correctly, and that
the wheel has been raised above from the floor (Fig._13 ref._G),
so that it does not slip during the following operations.
KEEP ON OPERATING RIM CLAMPING CON-
TROL, UNTIL REACHING THE MAXIMUM
OPERATING PRESSURE (130 BAR- 1885 PSI).
THE CAREFUL LUBRICATION OF THE TIRES
BEADS IS RECOMMENDED, IN ORDER TO PRO-
TECT THEM FROM POSSIBLE DAMAGES AND
TO FACILITATE MOUNTING AND DEMOUNTING
OPERATIONS.

AFTER COMPLETION OF TIRE MOUNT/DE-
MOUNT OPERATIONS DO NOT LEAVE THE
WHEEL CLAMPED ON THE SELF-CENTERING
CHUCK AND NEVER LEAVE IT UNATTENDED.
11.5 Bead breaker arms’ functioning
During the working phases, the the front bead breaker arm (Fig._16
ref._2) can maintain two firm positions, that is:
1. “working” position (wheel front side) (Fig._16 ref._3);
2. “off-work” position (Fig._16 ref._2).
In “working” position” (Fig._16 ref._3) the front bead breaker arm
isinfrontof the tire,justnexttherim. From thispositionitcan
perform the different tire bead breaking and mounting-demounting
operations.
The adjustment of the correct “working” position of the rear bead
breaker arm (Fig._16 ref._4) is performed through handle’s rotation
(Fig._16 ref._1).

11.6.1 Bead breaking
NEVER PLACE ANY PART OF YOUR BODY
BETWEEN THE BEAD BREAKER ROLLER AND
THE TIRE.
THROUGHOUT TIRE MOUNTING/DEMOUNT-
ING OPERATIONS, CHECK THAT THE WHEEL IS
FIRMLY CLAMPED BY THE EQUIPMENT CHUCK.
1. Clamp the wheel on the self-centering chuck as described in
“WHEEL CLAMPING” paragraph;
2. move the self-centering chuck to working position (rise fully
home) (Fig._13 ref._G);
3. move to work position A (Fig._5);
4. move rear bead breaker arm (Fig._17 ref._1) to work position with
therolleratapproximately5mm(0.2”)formrim’sedge,usingthe
lateral handwheel (Fig._17 ref._2).
5. move front bead breaker arm (Fig._17 ref._3) to work position,
using lever (Fig._13 ref._1-F).
6. carry out bead breaking of front bead first, then bead-break rear
bead, by turning self-centering chuck counter-clockwise (Fig._17
ref._4);
