1. COMMISSIONING
1.1 INTRODUCTION
1.1.a. PURPOSE OF THE MANUAL
The purpose of this manual is to provide the instructions necessary for optimum operation,
use and maintenance of your machine. If you sell this machine, please deliver this manual
to the new owner. Furthermore, ask the new owner to fill out the ownership transfer module
attached to the previous page in the manual and send it to Corghi, so that Corghi will be
able to provide the customer with all necessary safety information. Alternately, the new
owner can send an email to [email protected].
This manual presumes that the technicians have a thorough understanding of rims and
tyre identification and maintenance. He/she must also have a thorough knowledge of the
operation and safety features of all associated tools (such as the rack, lift, or floor jack) being
utilized, and have the proper hand and power tools necessary to work in a safe manner.
The first section explains the basic information regarding the safe operation of the Master
28 tyre changer family. The following sections contain detailed information regarding the
equipment, procedures and maintenance. Italics are used to refer to specific parts of this
manual that offer additional information or clarifications.
These references must be read in order to obtain information additional to the instructions
provided.
The owner of the tyre changer is the only person responsible for the observance of the
safety procedures and the organisation of technical training. The tyre changer must only be
used by qualified, specifically trained technicians. The owner or management is exclusively
responsible for storing the documentation relative to qualified personnel.
The range of Master 28 tyre changers is designed for mounting, demounting and inflating
tyres for light vehicles (cars, not trucks nor motorcycles) with a maximum external diameter
of 40 inches and a maximum width of 14 inches.
Additional copies of this manual and the documentation enclosed with the machine can be
requested from Corghi, specifying the machine type and serial number.
CAUTION: Design details are subject to change. Some illustrations may vary slightly in
appearance from the machine you have.

makes continuous reference to the possibility that accidents can occur. Any accident could
lead to serious or fatal injuries to the operator or people nearby, or cause material damage.

92 Artiglio Master 28 Operator’s manual
2. Overinflated tyres can explode, producing hazardous flying debris that may result in
an accident.
3. Tyres and rims that do not have the same diameter “do not correspond”. Never attempt
to mount or inflate tyres and rims that do not correspond. For example, never mount a
16.5” tyre on a 16” rim and vice versa. It is very dangerous. Tyres and rims that do not
correspond could explode and cause accidents.
4. Neverexceedtheinflationpressureforthetyreindicated
bythe manufacturerontheside of thetyreitself.Carefully
check that the air hose is well inserted in the valve
5. Never bring your head or other body parts close to a
tyre during inflation or bead insertion operations. This
machine is not a safety device against the possible risk
of explosion of tyres, air chambers or rims.
6. Maintain a suitable distance from the tyre changer while
inflating. Do not approach it.
A bursting tyre can cause projections of its parts in surrounding areas with a force
sufficient to cause serious injury or death.
Do not mount a tyre if its dimensions (indicated on the side) do not correspond
exactly to the rim dimensions (printed inside the rim) or if the rim or the tyre is
defective or damaged.
Never exceed the pressure recommended by the tyre manufacturer.
The tyre changer is not a safety device and does not prevent tyres and rims from
exploding. Keep all persons not working on the machine out of the working area.
DANGER

levels,
this cannot be used reliably to establish whether or not further precautions are necessary. The
factors which determine the level of exposure to which the operator is subject to include the
duration of the exposure, the characteristics of the workplace, other sources of noise, etc. The
permitted exposure levels may also vary according to the country. In all cases, this information
will enable machine users to better assess the danger and risks involved.

Artiglio Master 28 Operator’s manual 101
EN
1.2.e. AIR PRESSURE
The machine is equipped with an internal pressure limiting valve to minimize the risk
of over inflating the tyre.
•RISK OF EXPLOSION
•Never exceed tyre pressure recommended by
tyre manufacturer. Always match the tyre and rim
dimensions.
•Take care to avoid any injuries.
DANGER
1. Never exceed these pressure limitations:
• The supply circuit pressure (from the compressor) is 220 psi (15 bar).
• The operating pressure (indicated on the regulator) is 150 psi (10 bar).
• The tyre ination pressure (displayed on the pressure gauge) must never exceed the
pressure indicated by the manufacturer on the sidewall of the tyre itself.
2. Activate the air inflation jets only when inserting the bead.
3. Discharge the air pressure system before disconnecting the power supply or other
pneumatic components. Air is stored in a reservoir to operate the inflation jets.
4. Activate the air inflation jets only if the rim is correctly clamped on the tyre changer
(if required) and the tyre is completely mounted.
1.3. ADDITIONAL RIM/TYRE INFORMATION
Wheels equipped with pressure sensors and special rims or tyres could require
particular work procedures. Consult wheels and tyre manufacturer’s service
