Technical service and spare parts
For scheduled maintenance and any repairs to
the forklift, contact only the authorised service
network.
The authorised service network has personnel
trained by the manufacturer, original spare
parts and the tools necessary to carry out
maintenance and repairs.
Servicing by the authorised service network
and the use of original spare parts maintain
the technical characteristics of the forklift over
time.
Only original spare parts provided by the man-
ufacturer may be used for forklift maintenance
and repairs. The use of non-original spare
parts invalidates the warranty and renders the
user responsible for any accidents due to the
inappropriateness of the non-original parts.

General Precautions
NOTE
Some safety regulations to be followed when
using the forklift are listed below. These
regulations integrate those in the manual
"Rules for approved use of industrial vehicles".
General Safety Rules
• Only allow qualified, trained and authorized
personnel to use the forklift.
• Do not install equipment on the forklift un-
less supplied or indicated by the manufac-
turer.
• Maintain the forklift in full working efficiency
in order to limit any type of risk to the
minimum.
• Do not use the truck with bonnets or doors
open or with guards removed.
• The data plates found on the forklift must
be kept in good condition and replaced if
damaged.
• Carefully read and follow all of the safety
indications found on the forklift.
• Make sure that the forklift has sufficient
overhead clearance.
• Do not park the forklift in front of fire-fighting
devices or fire escapes or anywhere that it
blocks traffic.
• If the forklift shows signs of failure or
breakage and there is reason to consider
it unsafe, stop, park it, and notify the
maintenance manager.
• Maintain appropriate distances from high
voltage overhead cables. Comply with
the safety distances established by the
competent authorities.
• Never raise the load using just one fork.
• Place the load on the fork carriage or in such
a way that the centre of gravity of the load is
as close as possible to the fork carriage.
• The load must be placed on the fork arms
so that the centre of gravity falls lengthwise
on the mid point between the fork arms.
• Do not drive with loads off-centre laterally
with respect to the forklift’s median axis.
Lack of compliance with this regulation can
compromise forklift stability.
• Make sure that the surface on which the
load rests is able to support its weight.
• Always use safety clothing compliant with
current regulations and any personal pro-
tective equipment that may be applicable.
• Do not travel on loose or hilly ground or on
steps.
• Do not drive with loads raised more than
300 mm from ground level.
• Do not turn or stack on slopes.
• Reduce speed on slopes.
• Do not overload the forklift beyond the
capacity limits indicated on the capacity
plates.
Flooring requirements
The forklifts do not have a shock absorbing
system; therefore, the work floor must be even
and without holes, which can be difficult to
get around. Any stairs must be equipped with
accompanying ramps to prevent impacts with
the wheels, which affect the entire structure of
the forklift.
12 45418043404 [EN]

Safety 2
Safety regulations
CAUTION
DO NOT pass over cracks or damaged parts of the
floor with the forklift. Dirt and any objects in the work
path must be removed immediately.
Battery connection cables
CAUTION
Using sockets with NON-ORIGINAL battery con-
nection cables can be dangerous (see purchase
references in the parts catalogue)
Requirements for the traction-battery
charging area
When the traction battery is being charged, the
area must be sufficiently ventilated in order to
download or eliminate the gases produced
(EN 50272-3).
Safety Regulations Relative to Forklift Use
• The operator must familiarize himself with
the forklift to be able to better describe any
defects and assist maintenance personnel.
The operator, trained and authorized to use
the forklift, must be familiar with the controls
and performances of the forklift.
• Any defect (squeaking, leaks, etc.) must be
promptly reported because, if neglected, it
could cause more serious failures/defects.
• Carry out the inspections indicated in the
chapter on "Daily Inspections".
ENVIRONMENT NOTE
Report any oil and/or battery fluid leaks: they
are dangerous and highly polluting.
CAUTION
If you notice a burning smell, stop the forklift and
turn off the engine, then disconnect the battery.

Improper use and disposal of operating and
cleaning materials can cause serious damage
to the environment.
Always use and handle the operating materi-
als in a suitable manner and follow the manu-
facturer’s instructions for the product’s use.
Keep the operating materials only in contain-
ers intended for this purpose and in a location
that satisfies the requirements.
The operating materials may be flammable, so
avoid contact with hot objects or open flames.
When topping up the operating materials, only
clean containers should be used.
Follow the manufacturer’s safety and disposal
instructions regarding the operating and
cleaning materials.
Do not disperse oils or other operating liquids!
Any spilt liquid must be immediately collected
and neutralised with a binding material (such
as an oil binder) and then disposed of in
accordance with current regulations.
Always comply with anti-pollution regulations!
Before carrying out work that involves lubrica-
tion, filter replacement or hydraulic equipment
interventions, the area in question must be
thoroughly cleaned.
The replaced parts must always be disposed
of in accordance with the anti-pollution laws.
ENVIRONMENT NOTE
The incorrect or unlawful use of brake fluid is
harmful to people’s health and the environ-
ment.
Oils
• Do not allow to come into contact with the
skin.
• Do not inhale oil vapors.
• Wear appropriate means of individual
protection during forklift maintenance
operations (gloves, goggles, etc.) to
prevent the oil from coming into contact
with your skin.
ENVIRONMENT NOTE
The used oils and relative filters contain sub-
stances that are hazardous to the environment
andmustbedisposedofa
ccording to current
regulations. We advise youtocontacttheau-
thorised service network.
DANGER
The penetration in the skin of hydraulic oil that has
leaked under pressure from the forklift’s hydraulic
system is dangerous. If this type of lesion should
occur, contact a doctor immediately.
DANGER
Small high pressure jets of oil can penetrate the
skin. Look for any leaks using a piece of cardboard.
Battery Acid
• Do not inhale the vapor: it is poisonous.
• Use adequate means of individual protec-
tion to prevent contact with the skin.
• Battery acid is corrosive: if it should come
into contact with your skin, rinse abundantly
