5.1 Sound Alarm (in compliance with ISO6746-1 Standard) 

z  Sound alarm that is controlled at the driver’s position and reaches a minimum sound level of 93 

dB (A) at 7m from the front end of machine.   

z  When the machine has troubles and is unable to continue to work or work at a low speed, turn 

on all turn lights (direction indicator lamp, brake lamp, alarm lamp) to give out warning to 

others.   

z  Pay attention to the meters and alarms.   

5.2 Pay Attention to Drive Safety   

z  Please follow good operation practice in order to ensure the safety of yourself and others.   

z  Before starting vehicle, blow the horn to give out signal. Do not drive until it is confirmed that 

no people or obstacles around the vehicle.   

z  Do not stick body out of the vehicle.   

z  It is prohibited to use the bucket as a work platform or stand on it.   

z  Drive at the side of roads and take care to allow a passage for other vehicles to surpass. Keep 

distance.  

z  Try to avoid emergent brake operation.   

z  When driving at a high speed, it is highly risky to shift between forward and rear shifts. Try to 

avoid this operation.   

z  When driving or turning in narrow places, pay attention the surroundings and slow down to 

check whether there is any obstacle around.   

z  When the road condition is not good or the load is not stable, operate with care to prevent 

instability of the load.   

z  To ensure operation comfort of the driver and maximum life of transmission parts, slow down or 

brake before making gearshifts.   

z  When driving the machine, use parking brake to brake will cause severe wear of and damage to 

parking brake.   

5.3 Full-load Transportation 

z  Do not transport with highly lifted bucket full of materials, which is hazard. When transporting 

with full-load, select proper speed and lower down the bucket to an appropriate height 

 

36

(450-55mm from the ground) to lower the center of gravity an ensure stability of the vehicle.   

z  The weight of loaded materials shall not heavier than rated load weight of the machine; avoid 

overload. Chengdu Construction Machinery Co., Ltd is not liable to any machine damages or 

people injuries caused by overload.   

z  Avoid abrupt starting, abrupt stop or abrupt turning in transportation.   

5.4 Overspeeding Is Prohibited 

z  Get familiar with the performance characteristics of the vehicle and decide on appropriate speed, 

route and operation method according to the specific conditions of the site. Keep the relevant 

operators being informed.   

z  When driving in busy traffic of downtown or crossing lofty places, keep at a low speed to ensure 

the vehicle is under control at any time.     

z  When driving on rugged or slippery roads, or on hills, avoid high speed driving, abrupt turning 

or abrupt stop.   

z  The engine shall work smoothly. Abrupt turning in high speed driving is prohibited.   

5.5 Keep Good Visibility 

z  When visibility is not good in front, or at narrow crossings, slow down and hold on for a 

moment. Blow the horn to warn other vehicles or ask for guide by others when necessary; avoid 

imprudent operations.   

z  Dust, heavy fog and storm will affect visibility. Try to drive slowly when visibility is not good.   

z  Misjudgment on distance and height of ground is prone to occur in nights. Please drive at a 

speed suitable for the lighting condition.   

z  Turn on the headlights and roof lights when operating.   

5.6 Notices for Driving in Adverse Conditions 

z  When operating and driving in adverse conditions, special care shall be taken to ensure safety. 

Do not work alone in hazard places. Investigate beforehand on the condition of drive path, 

strength of bridge, topography and geography of work site.   

z  When moving in wet or floppy places, avoid falling of wheels and take care to effects of brake.   

z  When operating in water or swamp, do not let the bottom of drive axle contact with water. 

z  The earth piled up on ground or near trenches is floppy. It may collapse under the weight of 

machine or by vibration of machine, resulting in rollover of the machine.   

 

37

z  Avoid approaching suspensions or deep trenches. The weight or vibration of machine may cause 

collapse of these places and result in rollover of machine and people injuries.   

z  When there is a danger of falling rocks or rollover, use protective devices (FOPS & ROPS).   

z  When working in rainy days, the operation environment may vary from that when it begins to 

rain and special care shall be taken. There will be deposit on the ground after earthquake or 

explosion occurs and special care shall be taken.     

z  When working on snow ground, the loading operation may change significantly according to the 

types of the snow. The load shall be reduced and take care to avoid slipping of machine on the 

ground.  

5.7 Safe Drive on Slopes 

z  When driving on slopes, there is a danger of rollover of vehicle or sliding one side. Operate it 

with special care.   

z  When driving aside or changing directions on slopes, there is a danger of rollover of vehicle. Do 

not conduct this dangerous operation.   

z  When driving aside or changing directions on slopes, there is a danger of rollover of vehicle. Do 

not conduct this dangerous operation.   

z  Whenever it is practical, prefer to drive up or down slopes than on lanes or sidewalks.   

z  Select appropriate shift before driving down slopes. Never shift gears on driving down slopes. 

z  When driving on slopes, because the center of gravity of vehicle has shifted to the front wheels 

or rear wheels, operate with care and never brake abruptly.   

z  When driving on hills, banks or slopes, keep the bucket close to ground at a height of 

approximately 20～30cm (8—12inch). Lower the bucket down to ground in case of emergency 

to help stopping the vehicle or preventing rollover.     

z  When driving to slopes with full load: 

 Drive with the shift. 

Ⅰ

 

Move forward when climbing up and backward when descending.       

Do not turn.   

When the bucket is under load and the machine drives on the slope, if the bucket faces the 

direction of downgrade, the machine has the danger of rollover. 

z  When driving down slopes and needing to stop, adopt the braking method of stopping without 

cutting off the power, i.e. step on the brake pedal. At this time, the power shutoff switch shall
