Operating Temperature Range
To maintain the performances and prevent the earlier wear of machine, please abide by the following operating conditions.
●Do not operate the machine when the outside temperature is more than+45℃or less than-15℃
-The operations under+45℃outside temperature will probably result in engine overheating and deteriorated engine
performance. In addition, the hydraulic oil will probably become really hot to harm the hydraulic devices.
-The operations under 15℃outside temperature will probably harden the rubber parts (Such as gaskets) and cause earlier
wear or damage of machine.
-To operate the machine under the condition beyond above-mentioned outside temperature range, please consult with your
sales or service dealer.
Wearing Appropriate Clothing and Protective Appliances
●Do not wear loose clothing or wear decorative articles that will probably hitch to any
joystick or motion part.
●Do not wear oil or fuel contaminated clothing that is easily vulnerable to fire.
●As per the requirements of working environment, wear safety shoes, safety helmet,
safety goggles, filtration mask, thick gloves, ear flaps, and other protective appliances.
During the use of grinding miller, breaking hammer, or compressed air, please wear
appropriate protective appliances, such as safety goggles and filtration mask, as the
splashing of metal chippings or other objects will probably cause serious harms.
●Please use the hearing protection devices during the operations of machine.
Exposure to a high noise environment for a long time will result in harm or even complete loss of hearing.
Installation of Fire Extinguisher and First-Aid Kit
Fulfill the preparations for fire and accident.
●Install the fire extinguisher and first-aid kit and learn how to use them.
●Learn how to extinguish fire and handle accident.
●Know how to contact emergency aid and fabricate the emergency contact list.
SAFETY

No Disassembling of Safety Devices
●Please ensure that all guardrails, shelters, and doors are installed properly and
securely. Before operating the machine, please repair or replace damaged parts.
●Know how to use safety lock handle, seat belt, and other safety devices and
understand the correct operation methods.
●Do not disassemble any safety device, unless for the purpose of checking and repair.
Always keep all safety devices under good working condition.
Setup of Signaler and Flagman
Learn how to use the gestures of specific operation needs and designate the person
responsible for making gestures.
●All personnel must completely understand all gestures.
●The operator must respond to the gestures of designated person only. However, the
operator must abide by the stop gesture made by anyone in all cases.
●The signaler must stand in a clearly visible place while making the gestures.
Precautions for Standing up from or Leaving Driver Seat
●Before standing up from the driver seat to open/close windows or disassemble/install
the lower window, lower the working device onto the ground, lift up and lock the safety
lock handle, and stop the engine.
When the safety lock handle is lowered down (Unlocked), the accidental touch of any
joystick will result in sudden movement of machine and cause serious injuries or deaths.
●Please be noted that, even if the safety lock handle is placed at locking position, the bulldozing blade, boom, and auxiliary
hydraulic controls can’t be locked. Do not touch such controls accidentally.
●While lifting up or lowering down the safety lock handle, take cautions not to touch any joystick.
Before leaving the driver seat, lower the working device onto the ground, lift up the safety lock handle to locking position, and
stop the engine. Meanwhile, ensure to withdraw the key, close the doors and hoods, and carry the key with you and then preserve
it in a designated place.
Guard against Fire and Explosion Dangers
Keep fuel, lubricating oil, grease, and antifreeze away from flame. The fuel is especially inflammable and really dangerous.
●Handle these inflammable away from ignited cigarette, match, lighter, and other flame
or fire source.
●Do not smoke or use open fire while handling fuel or performing the operations of fuel system.
●Do not leave the operation site while filling fuel or lubricating oil.
●Do not disassemble the fuel tank cap or refuel while the engine is running or is not
cooled down. In addition, do not splash fuel to any machine hot surface or electronic system part.
●Immediately clean the overflown fuel or lubricating oil thoroughly.
●Check for leakage of fuel and lubricating oil. Please eliminate the leaks and clean the machine before operations.
●Please move the inflammable to a safe place before polishing or welding operations.
●Do not cut or weld any pipeline or pipe that probably contains inflammable liquid. Please clean thoroughly by non-inflammable
solvent before cutting or welding.
●Remove all wastes and impurities from machine. Ensure that there is no oil contaminated rag or other inflammable on the
machine.
●Handle all solvents and dry chemicals (Foam fire extinguisher) as per the manufacturer’s procedures indicated on the
containers. Operate in a well-ventilated place.
●Never use fuel for cleaning purpose. Always use non-inflammable solvent.
●Please open doors and windows for thorough ventilation during the handling of fuel and the cleaning of oil stain or paint.
●Preserve all inflammable liquids and materials in a safe and well-ventilated place.
●The short-circuit of electric system will probably result in fire. Daily check the wire connections for looseness and damage.
Re-tighten loose connectors and cable clamps. Repair or replace damaged wires.

●Fire accident caused by pipelines: Ensure that the clamps, protection devices, and cushion pads of hoses and pipes are
securely fixed. In event of looseness, the hoses and pipes will be damaged due to vibration or contact with other parts during
operations. This will probably result in spray of high pressure oil to cause fire accident or harms.
Toxic Exhaust Gas from Engine
●Do not operate the engine in an enclosed place with poor ventilation.
●If the natural ventilation is not possible, install ventilation fan, fan, extended exhaust pipe,
or other ventilation device.
