VII Safe Parking 

7.1 Pay Attention to Safety of Yourself and Others

 

Choose a lot as flat as possible to park the machine. Lower the work device down to ground.   

Do not park on slopes. When it is not avoidable to park on a slope, the degree of slope must be 

lower than 1/5 and wedges shall be put under the wheels to prevent the machine from moving. 

When the vehicle breaks or it is needed to park it at a place where the traffic is busy, set up an 

enclosure, signal, flag or alarm light, or set up other necessary signals to ensure the vehicles 

passing by are able to identify this machine clearly. And do not let the machine, enclosure, or 

flag obstruct traffic.   

z  When parking, unload the materials in the loader, lower down the bucket completely to the 

ground, turn off the engine, and press the parking switch button and turn of the power switch. 

Lock all devices with the key and take off the key. 

      It is prohibited to climb up the vehicle when it is transporting.   

7.2 Notices for Cold Regions

 

After completing work, remove water, snow or silt that clings to wires, plugs and sockets, 

switches or sensors, or the cover parts of these parts, If not removing these stuff, the water 

contained in them will freeze and cause failure of machine when starting the machine next time. 

Unexpected malfunction may be inflicted.     

Preheat thoroughly. If the machine is not preheated thoroughly before operating, the 

reaction of machine be slow, which may cause unexpected accidents.   

Operate the control levers to cycle the hydraulic oil in the hydraulic system (raise system 

pressure to set pressure, then release the pressure to allow the oil flow back to hydraulic oil 

tank), which will raise the temperature of hydraulic oil. This will guarantee good response of the 

machine and prevent failures.   

If the electrolyte in storage battery has frozen, neither charge the storage battery nor start 

engine by other power supplies. This could be dangerous and cause the storage battery to catch 

fire.  

When charging or start engineer by other power supplies, melt the electrolyte in storage 

battery before starting and check whether there is any leakage.

VIII Safety Inspection and Maintenance 

8.1 General Knowledge

 

The operating and maintenance personnel shall receive trainings and obtain corresponsive 

qualifications; the people who are irrelevant to the maintenance and repair work being 

conducted are not allowed to enter into work area. Appoint people to watch over when 

necessary.  

The repair of vehicles shall be conducted in compliance to specified procedures. When not 

knowing how to conduct, seek assistance from Sichuan Chengdu Construction Machinery Co., 

Ltd.  

Observe the cautions indicated by warnings label. Labels concerning especially important 

issues are attached on the vehicle; follow these instructions.   

Before starting maintenance work, adhere labels marked with “please do not operate” or 

other similar labels on starting switches and console. Prevent others 

from starting engine or manipulate control levers. Injuries or death to 

operator may be caused otherwise.   

When operating or maintaining the machine, shall not wear loose 

clothes or jewels, or else they may get entangled on the control lever or 

other parts of the machine.   

Ensure all protective boards and covers are fixed on the machine.   

Fuel and engine oil are hazard items. Fuel, engine oil, lubricant and oil cloth shall not 

contact any fire or flame.   

The parts removed from the machine shall be stored in a safe place. Make sure that the parts 

will not fall off. Set up baluster surrounding the place and hang labels of “forbidden to enter” in 

prevention of approach by unapproved people.   

The work site shall be kept clean and tidy, without cast oil cloth, lubricant, etc., to prevent 

occurrence of fire or falling off of people.   

Before inspecting and repairing the machine, fix the front and rear frames with lock rod to 

avoid injured caused by their rotation.   

When it is necessary to conduct inspection and maintenance work with the movable arm 

bucket being lifted, must use necessary movable arm oil cylinder support device to prevent

falling of the work device and place all control levers at middle position. Lock the neutral shift 

lock switch to avoid incorrect manipulation.     

Part the machine on horizontal ground and place the gearshift control lever at neutral 

position. Place the hydraulic control lever at maintaining position, turn off engine, and turn the 

key to “0” position, take away the key and engage parking brake. Turn off the master switch. 

Unapproved people are not allowed to be on the machine.   

Put the accessories in order, such as lunch pail, tools or other accessories irrelevant to the 

machine.  

Understand the hand signals and who commands at sight. Only receive signal from one 

person.  

8.2 Working in Enclosed Places 

   The waste gas exhausted from engine may inflict sickness and even death. In case it is 

unavoidable to start engine at an enclosed place, use venting device to discharge the waste gas in the 

area. Open doors for ventilation when no venting device is available.   

8.3 Working underneath the Machine 

z  Park the machine on solid flat ground. Lower down the work device to ground before starting to 

maintain or repair underneath the machine.   

z  Keep the tyres in place by wedges.   

z  If letting the tyres off the ground and supporting only with the work device, it is very dangerous 

to work underneath the machine.   

z  Never work underneath the machine which is not properly supported.   

z  When inspection and repair can only be conducted with the work device being lifted, install oil 

cylinder safety stand on the piston rod of the moveable arm.   

Method of using the protective frame: 

      Hang the safety stand for the lifting arm at rear frame when not using it.   

   When using it, take off the safety stand, lift the movable arm until the safety stand 

completely lock in the piston of movable arm cylinder, install bolts and nuts.   

8.4 Working at top of the Machine 

z  When maintaining at top of the machine, ensure the standing point is clean and free of obstacles.   

z  Use protective device when necessary.

z  The top of engine cover is slippery and hazard and people are not allowed to stand on it.   

z  The top of tyre is slippery and hazard. Do not stand on it.   

z  When cleaning the front windows of the cab, stand on fender of the front frame.   

8.5 Maintaining When Engine Is Running

 

Do not maintain when engine is running to avoid injuries. When it is unavoidable to maintain 

with engine running, comply with the following instructions. 

z  Appoint one worker to sit on the operator’s seat to prepare to turn off the engine at any moment. 

All workers must keep contact with others.   

z  Do not touch tail pipe, muffler and other high temperature parts to avoid burnings.   

z  When the work position is close to rotating parts, there is a danger of being rolled in by the 

rotating parts. Special care must be taken.   

z  Do not touch any control lever. When it is unavoidable to manipulate control levers, give out 

signals to other workers, warning them to walk to safe places.   

z  Never let any tool or any part of body contact with the fan blades or fan belt. Severe injuries 

may be caused or else.   

8.6 Do not Drop Foreign Matters into the Machine 

z  When opening the exam windows or oil filler to exam and repair, take care not to drop any 

foreign matter (such as nuts, bolts, cotton yarn or tools) into the machine. If these articles fall 

into the machine, must take them out of the machine.   

z  When repairing, do not carry any unnecessary tools or parts in the pockets.     

8.7 Cleaning 

z  Clean the machine in time. This will avoid the dirt or silt on the machine to splash into eyes. 

The oil on the machine may cause slip and injuries.   

z  When cleaning the machine, use incombustible cleaning agent.   

z  When cleaning inside the machine, turn off engine and place all control levers at middle position. 

Pull up the parking brake switch and place it at brake position.   

z  Wear anti-skid shoes to avoid slipping on wet surface when cleaning the machine. When 

washing machine with pressured water, wear protective clothes.   

z  Do not jet water directly on electrical units (such as sensors and plugs and sockets of wire). If 

water enters into electrical system, operation failure may be inflicted.
