FOREWORD
Proper operation, maintenance, troubleshooting and repairs are necessary to preserve the performance
of the pallet truck over along period of time and ensure that fault and breakdowns do not occur. The
object of this service manual is to provide the information necessary especially in connection with the
performance of inspections and repairs mainly in the maintenance areas.
The majority of this pallet truck consists of steel, it can be completely recycled. Waste
material in conjunction with repairs, maintenance, cleaning or scrapping, must be collected and disposed
of in an environment-friendly way and in accordance with the directives of respective countries. Such
work must be carried out in areas intended for this purpose. Recyclable material should be taken care of
by specialized authorities. Environmentally hazardous waste, such as oil filters, batteries and electronics,
will have a negative effect on the environment, or health, if handled incorrectly.
All of the information reported herein is based on data available at the moment of
printing. Our products are constantly being developed and renewed, we reserves the right to modify our
own products at any moment without prior notice and incurring in any sanction. So, it is suggested to
always verify possible updates.

1. GENERAL
1.1 INTRODUCTION – MAINTENANCE SAFETY PRECAUTIONS
Careless performing of the easy work may cause injuries. Take care to always perform work safely, at
least observing the following. It is of utmost importance that maintenance personnel pay strict attention
to these warnings and precautions to avoid possible injury to themselves or others, or damage to the
equipment. A maintenance program must be followed to ensure that the machine is safe to operate.
The specific precautions to be observed during maintenance are inserted at the appropriate point in the
manual. These precautions are those that apply when servicing hydraulic and larger machine
component parts.
MODIFICATION OF THE MACHINE WITHOUT CERTIFICATION BY A
RESPONSIBLE AUTHORITY THAT THE MACHINE IS AT LEAST AS SAFE AS ORIGINALLY
MANUFACTURED, IS A SAFETY VIOLATION.
SINCE THE MACHINE MANUFACTURER HAS NO DIRECT CONTROL OVER THE
FIELD INSPECTION AND MAINTENANCE, SAFETY IN THIS AREA RESPONSIBILITY OF THE
OWNER OR OPERATOR.
FAILURE TO COMPLY WITH SAFETY PRECAUTIONS LlSTED IN THIS SECTION
MAY RESULT IN MACHINE DAMAGE, PERSONNEL INJURY OR DEATH AND IS A SAFETY
VIOLATION.
When carrying out any operation or maintenance, have trained and experienced personnel carry out
the work.
When carrying out any operation or maintenance, carefully read out Operation and Maintenance
Manual.
Read all the precautions given on the decals which are fixed to the machine.
Be sure you fully understand the contents of the operation. It is important to prepare necessary tools
and parts and to keep the machine.
Your safety, and that of others , is the first consideration when
engaging in the maintenance of equipment. Always be conscious of
weight. Never attempt to move heavy parts without the aid of a
mechanical device. Do not allow heavy objects to rest in an
unstable position. When raising a portion of the equipment, ensure
that adequate support is provided.

4
It should be noted that the machines hydraulic systems operate at
extremely high potentially dangerous pressures. Every effort should
be made to relieve any system pressure prior to disconnecting or
removing any portion of the system. Relieve system pressure by
cycling the applicable control lowering button several times with the
motor stopped and ignition on, to direct any line pressure back into
the reservoir. Pressure feed lines to system components can then
be disconnected with minimal fluid loss.
Remove all rings, watches and jewelery when performing any maintenance.
Wear well-fitting helmet, safety shoes and working Clothes When
drilling grinding or hammering always. Wear protective goggles.
Always do up safety clothes properly so that they do. Not catch on
protruding parts of machines. Do not wear oily clothes. When
checking, always release battery plug. DO NOT WEAR LONG
HAIR UNRESTRAINED, OR LOOSE-FITTING CLOTHING AND
NECKTIES WHICH ARE APT TO BECOME CAUGHT ON OR
ENTANGLED IN EQUIPMENT.
During maintenance do not allow any unauthorized person, to
stand near the machine.
Flames should never be used instead of lamps. Never use a buring
flame to check leaks or the level of oil or electrolyte.
Immediately remove any oil or grease on the floor of the operator’s
compartment or on the handrail. It is very dangerous if someone slips
while on the machine.
Always use the recommended pure oil or grease, and be sure to use clean containers.
Oil is a dangerous substance. Never handle oil, grease or oily
clothes in places where there is any fire or flame. As
preparation for use of fire extinguishers and other fire- fighting
equipment.
Keep the battery away from fire hazards. The generated gases
are explosive.
Store all the oils in a specified place.
Keep the flammable things away from the machine. Do not
smoke in the working site.
Battery should always be disconnected during replacement of electrical components.

5
Always use the grades of grease and oil recommended by NOBLELIFT choose the viscosity
specified for the ambient temperature.
Exhaust gas is dangerous provide ventilation when working in a closed
space.
Avoid breathing dust that may be generated when handling components
containing asbestos fibers. Wear a gas mask if necessary.
When working on top of the machine, be careful not to lose your balance
and fall.
Hand a caution sign in the operator’s compartment (for example “Do not
start” of “Maintenance in progress”). This will prevent anyone from
starting or moving the machine by mistake.
When welding on the machine or working on the electical system,
ALWAYS turn the key switch OFF and remove the battery plug
from the battery. Park the machine on firm, flat ground. Lower the
fork to the min. height and stop the motor.
Sulfuric acid in battery electrolyte is poisonous. Ist is strong
enough to burn skin and eat holes in clothing. If you spill acid on
your clothes or skin, immediately flush it with large quantities of
water.
When working on the battery, wear goggles or safety glasses. If
splashed into the eyes, flush with water and get medical attention
immediately.
Battery terminals touched by metal objects can cause short circuit
and burn you. Keep tools away from the terminals.
When disassembling and assembling the battery, make sure that
the battery terminals (+, –) are correctly connected.
If water gets into the electrical system, abnormal operation or
failure can result. Do not use water or steam on sensors, connectors
and instruments in the cab.
Do not handle electrical equipment while wearing wet gloves, or in wet
places, as this can cause electric shock.
When working with others, choose a group leader and work according to his instructions. Do not
perform any maintenance beyond the agreed work.
Unless you have special instructions to the contrary, maintenance should always be carried out with
the motor stopped. If maintenance is carried out with the motor running, there must be two men
present : one operating the pallet truck and the other one performing the maintenance. In such a
case, never touch any moving part.

6
Before making adjustment, lubricating or performing any other maintenance, shut off all power
controls.
When removing parts containing O-ring Gaskets or seal. Make sure clean the mounting surface and
replace with new sealing parts.
Thoroughly clean the machine. In particular, be careful to clean the grease fittings and the area
around the dipsticks. Be careful not to let any dirt or dust into the system.
Use only approved, nonflammable cleaning solvents.
When changing the oil or fitter, check the drained oil and filter for any signs of excessive metal
particles or other foreign materials.
Always use NOBLELIFT genuine parts for replacement. ENSURE REPLACEMENT PARTS OR
COMPONENTS ARE IDENTICAL OR EQUIVALENT TO ORIGINAL PARTS OR COMPONENTS.
When checking an open gear case, there is a risk of dripping things in. Before removing the covers
to inspect such cases, empty everything from your pockets. Be particularly careful to remove
wrenches and nuts.
