Foreword
Proper operation, maintenance, trouble shooting and repair are necessary for long-term use of the vehicle while
ensuring that the vehicle does not break down again. The purpose of this service manual is to provide the necessary
information especially for inspection, repair and maintenance.
The main material of this car is steel, which can be completely recycled. Waste from repair, maintenance and
cleaning must be disposed of in an environmentally friendly manner and in accordance with the instructions of
the respective countries. Recyclable materials should be handled by a specialized department. Environmentally
harmful Hazardous waste, such as waste batteries, waste oil and electronic products, if not handled properly, will
have a negative impact on the ecological environment or human health。
All the information here is what we gathered before printing the manual. Our products are constantly
developed and updated, we have the right to modify our products at any time without notice. Therefore,
we recommend that you verify the updated content。

1.GENERAL
1.1 Introductions – Maintenance safety precautions
Maintenance work may cause injuries. Always take care to perform work safe, 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, 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, for the most parts, those that apply when servicing
hydraulic and larger
truck component parts.
MODIFICATION OF THE TRUCK WITHOUT CERTIFICATION BY A RESPONSIBLE
AUTHORITY THAT THE TRUCK IS AT LEAST AS SAFE AS ORIGINALLY MANUFACTURED, IS A
SAFETY VIOLATION.
SINCE THE TRUCK MANUFACTURER HAS NO DIRECT CONTROL OVER THE
FIELD INSPECTION AND MAINTENANCE, SAFETY IN THIS AREA RESPONSIBIUTY OF THE
OWNER OR OPERATOR.
FAILURE TO COMPLY WITH SAFETY PRECAUTIONS, LlSTED IN THIS SECTION
MAY RESULT
 When carrying out any operation or maintenance, have trained and experienced
personnel to carry out the work.
 When carrying out any operation or maintenance, carefully read operation and
maintenance handbook.
 Read all the precautions given on the decals which are fixed to the truck.
 Be sure you fully understand the content of the operation. It is important to
prepare necessary tools and parts for maintain the truck.
 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.
 It should be noted that the machines hydraulic systems operate atextremely 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 several times with the engine(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 jewelry 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 naked 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 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 at the working
place.
 Battery should always be disconnected during replacement of electrical
components.
 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 electrical 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. It is strong enough to
burn skin and eat holes in clothing. If you spill acid on your clothes or
skin, immediately flush with large quantities or 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.
 Keep sparks, lighted matches, and open flame away from the top of battery.
Battery (hydrogen) gas can explode.
 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 other, 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 technicians present: One operating the stacker and the other one
performing the maintenance. In such a case, never touch any moving part.
 Before making adjustment, lubricating or performing any other maintenance, shut off all power
controls.
 When removing parts containing O-ring Gaskets or seal 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.
