ous potential hazards that may arise during the
inspection and maintenance work, and select
appropriate safety protective devices according
to the work type and work place conditions, such
as safety helmets, protective masks, protective
gloves, goggles, protective clothing, safety belts
and safety shoes.
•Before carrying out inspection and maintenance
work, check that the protective devices are not
damaged and are used correctly.
•Safety protective devices must be inspected

© May 2023 6GTZZ14EJ&16EJ Maintenance Manual
MAINTENANCE SAFETY PRECAUTIONS
regularly and replaced if any damage is found.
3. Choose appropriate repair tools.
•Before conducting any inspection and mainte-
nance work, the maintenance personnel shall
prepare appropriate maintenance tools as re-
quired by the work, such as wrench, screwdriver,
pliers, multimeter, pressure gauge, lubrication
device, jack and lifting equipment.
•While choosing a jack or lifting equipment, con-
firm whether its carrying capacity can meet the
requirements of use. Refer to the Weight of Ma-
jor Components section to select the device
with sufficient load capacity.
•Service tools must be kept clean and in good
condition.
4. Lock the wheels after the machine is parked to pre-
vent it from rolling.
5. Do not perform inspection and maintenance work
after the machine is started.
•Before performing inspection and maintenance
work, make sure the machine is turned off and

to ensure safety during the maintenance process as ap-
propriate for the working environment.
2.3 MAINTENANCE SAFETY

MAINTENANCE SAFETY PRECAUTIONS
GTZZ14EJ&16EJ Maintenance Manual 7©May 2023
Unsafe Maintenance Hazard
• Before performing any adjust-
ment or service operations, power
off all control units and ensure
that all moving parts are securely
secured and free from accidental
movement.
• Before performing any adjust-
ment or service operations, en-
sure that the boom is stowed, and
do not work under the raised plat-
form/boom. If anyone needs to
work under the raised platform/
boom, the platform and boom
must be supported with appropri-
ate safety supports.
• When lifting or moving heavy
parts of the machine, use equip-
ment with sufficient capacity, and
never place heavy objects in un-
stable positions after moving.
• When machine parts are lifted by
other equipment, ensure that
there are no people under and
around the equipment.
• When striking the brass rod with
a mallet, make sure to wear
goggles.
• If you need to replace parts, use
the original parts specified by
Sinoboom.
• Do not wash the machine with
water. The machine contains
many electronic components
such as solenoid valves and sen-
sors, which may fail or work
poorly after water ingress. If water
washing is necessary, please turn
off the main power switch firstly,
and dry the machine thoroughly
before connecting the power.
• Make sure the machine is turned
off before using flushing equip-
ment (such as high-pressure
water gun) to clean the machine. It
is forbidden to direct the water or
vapor ejected from the flushing
equipment at the electrical com-
ponents, or short circuit or elec-
tric shock may result.
• After maintenance, clean the
spilled hydraulic oil thoroughly
and do not spill the hydraulic oil
on the ground.
• After maintenance, immediately
wash any hydraulic oil on the
skin.
• Waste hydraulic fluids, fuels,
coolants and refrigerants should
be recycled or disposed as per lo-
cal regulations.

MAINTENANCE SAFETY PRECAUTIONS
High Temperature and High Pressure
Hazards
• Some parts may have high sur-
face temperature when the ma-
chine is running or after the
machine has running for some
time, which may cause burns
through skin contact. Do not
touch any hot parts!
• It is forbidden to repair or tighten
hydraulic hoses or seals while the
machine is live or when the oil
system is under pressure.
• Before loosening or disassem-
bling the hydraulic parts (espe-
cially the counterbalance valve on
the cylinder), ensure that the hy-
draulic pressure of all hydraulic
lines is released and that the hy-
draulic oil is completely cooled
down.
• Disassemble the hydraulic com-
ponents slowly to prevent the hy-
draulic oil from splashing and
injuring people.
• It is forbidden to check the hy-
draulic leakage point by hand.
Use a piece of cardboard or stiff
paper to find leaks, and wear
gloves to protect your hands from
hydraulic fluid sprays.
• Do not operate the machine in
case of hydraulic oil or air leaks.
Oil or air leakage from the hy-
draulic system may penetrate and
burn the skin.
• It is forbidden to plug leaking hy-
draulic oil by hand. If there is a
leak, the pressure of the hydraulic
system should be released first,
and the maintenance should be
carried out after the hydraulic oil
has cooled down.
• If you are injured by ignoring the
dangers of high temperature and
high pressure, seek immediate
medical attention. If treatment is
not carried out immediately, seri-
ous complications can result.
Welding and Polishing Operation
Hazards
• Welding, grinding and polishing
operations must follow the appro-
priate local safety operating
procedures.
• Before performing welding, grind-
ing and polishing operations, the
machine should be powered off,
and ensure that the wires or ca-
bles are connected correctly.
• Do not use the machine as a
ground wire during welding and
grinding operations.
• Always make sure that all power
tools are completely placed within
the perimeter of the platform. Do
not hang the wires of power tools
on the guardrail of the platform or
in any work area outside the plat-
form, or hang the power tools di-
rectly with wires.
Fire and Explosion Hazards
• Do not operate the machine,
charge the battery or refuel the
machine in places where poten-
tially flammable or explosive
gases may be present.
• Refueling and charging should be
carried out in a well-ventilated
place without flames, sparks, and
other hazards that may cause fire
or explosion.
• For machines powered by an en-
gine, do not refuel the machine
while the engine is running.
• Never spray ether into the engine
with a glow plug (if the machine is
equipped with an engine).
• Never touch the battery terminals
or cable clamps with tools that
can generate sparks.
• Only approved non-flammable
cleaning solutions should be used
on the machine.
