The use of non genuine parts may cause damage to people or
objects
1.5 Scrapping
When your machine’s working life is over and it can no longer be used, it must
be made inoperative by removing any connection to power sources. These
units are considered as special waste material, and should be broken down into
uniform parts and disposed of in compliance with current laws and regulations. If
the packing are not polluting or non-biodegradable, deliver them to appropriate
handling station.

Packing, Transport, Storage
3.1 Packing
The packing of the lift is delivered in following components:
• No. 2 base units, each one with a runway equipped with 2 hydraulic
cylinders.
• No. 1 rolling jack with an air/hydraulic pump.
• No. 1 control unit and containing hydraulic unit, hydraulic hoses, air hoses,
anchor bolts, rubber blocks and the technical files.
• No. 2 turntable recess covers.
• No. 2 drive-on ramps, 2 front wheel stops and 4 hose protective covers if
the lift is ordered for on-floor installation.
(If requested, optional accessories are available to satisfy each customer’s
requirements).
3.2 Lifting And Handling
When loading/unloading or transporting the equipment to the site, be sure to
use suitable loading (e.g. cranes, trucks) and hoisting means. Be sure to hoist
and transport the components securely so that they cannot drop, taking into
consideration the package’s size, weight and center of gravity and it’s fragile
parts.
Hoist and handle only one package at a time.

Packing, Transport, Storage 11
12ASL
In Figure 1 there are the correct indications for the lifting of the runways:
Figure 1 – Loading/Unloading Runway
3.3 Storage And Stacking Of Packages
Packages must be stored in a covered place, out of direct sunlight and in low
humidity, at a temperature between 14°F and 104°F.
Stacking is not recommended: the package’s narrow base, as well as its
considerable weight and size make it difficult and hazardous.
3.4 Delivery And Check Of Packages
When the lift is delivered, check for possible damages due to transport and
storage; verify that what is specified in the manufacturer’s order confirmation is
included. In case of damage in transit, the customer must immediately
inform the carrier of the problem.
Packages must be opened paying attention not to cause damage to people (keep
a safe distance when opening straps) and parts of the lift (be careful the objects
do not drop from the package when opening).

Product Description
4.1 Lift Description (Ref. Figure 2)
This lift has been designed for the lifting of motor-vehicles for wheel alignment
and maintenance. The lift can be mounted either on a concrete surface or in a
recessed pit. The maximum lifting weight is as specified on the serial plate. All
mechanical frames, such as platforms, extensions, base frames and arms have
been built of steel plate to make the frame stiff and strong while keeping a low
weight. The electro hydraulic operation is described in detail in chapter 8.
This chapter describes the lift’s principal elements, allowing the user to be
familiar with the lift. As shown in figure 2, the lift is composed of two runways
P1 (1) and P2 (2) with two rolling jacks (3), anchored onto the floor by means
of two bases (4). Runways are linked to the base by means of a scissors lifting
system.
The lifting system of each runway is composed of scissor arms (5) and a
hydraulic cylinder (6). Turntable recess covers (7) are supplied with the lift in
case for non-alignment purposes. The lifting and lowering motion of lift and
wheel free jacks is carried out by operation of a control unit (8) placed next to
the lift.
The leveling system of the lift is carried out manually by operation of the leveling
cocks in the power unit. The mechanical safety operating by a pneumatic
cylinder (9) is built under each runway and wheel free jack for engagement and
release. Two limit switches are installed in the P1 base: for top position limit and
for the safety height limit.

Figure 2 – Lift
4.2 Operation
Lifting is carried out by the hydraulic unit which activates the cylinders. The
platforms are raised simultaneously by cross fed lines to the hydraulic cylinders.
Lowering, even though electrically controlled, is carried out by the weight of
both the platforms and the load lifted. Lowering motion of the wheel free jacks
with load less can be sped up by means of pneumatic action in the chamber of
its slave cylinder. The hydraulic system is protected by a max pressure valve
thus preventing pressure from exceeding the maximum fixed safety limit. The
synchronization of the platforms is carried out by a master/slave circuit.
Lifting and lowering motion on the lift is controlled by the push buttons on
the control panel. Whenever the lift has to be lowered to the ground and the
lowering button is pressed, the lift will stop about 18in. from the ground. This
way, the operator must verify that neither persons nor objects are within the
safety area. If clear, the final lowering button can be pressed and the lift fully
lowered. A beeping sound is heard during the last travel.
