However, safety precautions given on the following pages are also applicable to lift trucks that have special specifications or attachments. Read this manual thoroughly and become completely familiar with your truck to get the most out of it.
1. Know your truck
For the purpose of doing material handling job, the forklift truck is different from general passenger cars is structure as follows: Poor front view due to the hoist system. Rear wheel steering lets the rear of the truck swing outwards when going around corners. Compactly designed, the forklift truck is heavy. Most of the weight of the truck is heavy. Most of the weight of the truck and loads is on the front wheels when loaded so the truck stability. Read the operator's manual and name plates on the truck, and become familiar with your truck and operating procedures. If there is something in the manual you do not understand, ask your supervisor to explain it to you.

2. Get permission from supervisor.

Only trained and authorized operator shall be permitted to operate the truck.

 

3. Make periodic checks
Inspect the truck at periodic intervals for oil or water leak, deformation, lousiness, ect. if neglected, short life of components will be caused and in the worst case a fatal accident would occur. make sure having replaced good parts during periodic check. Wipe oil, grease or water from the floor board and foot and hand controls, if any. Strictly prohibit smoking and spark nearby the storage battery when checking it. If maintenance on high position, such as mast, front and rear lamp, please be careful to prevent fall down clamped. Be careful do not be scalded when inspect the motor, controller and ect.
4. Stop using the forklift when it is in trouble 

Whatsoever in trouble, you must stop the forklift, hang a mark of “danger” or “trouble” and take off the key, at the same time inform the manager. Only after the trouble is removed, you may use the forklift.

5. Protect yourself
Operation must wear helmet, safety shoes and work clothes.
6. Prevent exploding
Because there will bring exploding gas in the bosom of the battery, prohibit any flame nearby it absolutely. 

Don't let any tools close the two terminal of the battery to avoid spark or short circuit. Make sure to operate the truck on concrete firmly enough or bituminous macadam.

9. Start safely
Before starting up, make sure that:
The parking brake lever is applied securely.
The foward-reverse lever is in neutral.
Before starting, make sure no one is under, on and close to the truck.
Don't step the accelerate pedal or control the lifting lever or tilting lever before turning on the power.
10. Prohibit sudden stop or turning
Operate the controls smoothly. Avoid
 

Sudden stops or turns.
It is dangerous to make a sharp brake. otherwise the truck has the possibility of overturn.

11. Pay attention to the route of the truck
-Pay attention to the route of the truck. be sure to make a wide sight.

12. Don't offer rides to others
Never allow other person(s) to ride on the forks, pallets or on truck.

13. Know the load to be handled
Taking account of the shape and material of the load to be handled, use a proper attachments and tools.
Avoid hoisting the load, with wire rope hung

11


on the fork or attachment, since the wire rope may slide off. If needed, a qualified personnel for slinging operation should performed, making use of a hook or crane arm attachment.
Take care not to protrude the forks out of the load. The protruded fork tips may damage or turn over the adjacent load.
14. Know capacity of truck
Know the rated capacity of your lift truck and its attachment, if any, and never exceed it.

Do not use a man as an additional counterweight. It's quite dangerous.
15. Don't daydream
Keep your mind on your work. Learn to anticipate danger before it arises.

16. Remain seated

21. Avoid be clamped by the mast
It is forbidden to put your hands, arms or head stretch between the mast and safeguard.
It is forbidden to put your hands in inner and outer mast.
 

 

12


22. Prohibit load off center
the goods is liable to drop turning or passing rough road when it departures the center. And the forklift may turn over more probably.

23. Don't stack load too high on forks

 Don't stack load too high on forks in such a way that the top of loads exceeds the load backrest height. If unavoidable, make the load stable securely. When handling bulky loads that restrict your vision operate the truck in reverse or have a guide

24. Don't tilt the mast with load high
Use minimum forward and reverse tilt when stacking and unstacking loads. Never tilt forward unless load is over stack or at low lift height.
When stacking loads on a high place, once make the mast vertical at a height of 15 to 20 cm above the ground and then lift the load farther. Never attempt to tilt the mast beyond vertical when the load is raised high. To unstack loads from a high place, insert forks into pallet and drive backwards, then lower the load. Tilt the mast backwards after lowering. Never attempt to tilt the mast with the load raised high.

25. To handle bulky loads
When handling bulky loads, which restrict your vision, operate the machine in reverse or have a guide. When you have a guide, make sure you understand hand, flag, whistle or other signals.
When operating with long loads such as lumber, pipe, ect., or in the case of the Large-sized model or the truck with spreader, be extremely careful of load end swing at corners or in narrow aisles. Be alert for fellow workers.
26. Carry the load low
It is dangerous to travel with forks higher than appropriate position regardless of whether loaded or not. Keep the good travelling posture. (When Travelling, the forks should be 1 to 30 cm above ground or floor.)
Do not operate the side shift mechanism. If

 

13


equipped, when the forks are raise and loaded, since this will cause the truck to be unbalance.

27. Tilt backward when loaded
Travel with load as low as possible and tilted back. If operating with steel pallet or the like, be sure to tilt back the mast to prevent it from slipping off the forks.

28. Watch for doorways and Slow down at corners
Watch for branches, cable, doorways, or overhangs. Use caution when working in congested areas.
Slow down and sound horn at cross aisles and other locations where vision is restricted. When make a turn, be sure the speed of the truck is lower than the ⅓ max. of allowable speed.

29. Keep some distance from roadside and flat roof
Affirm keeping some distance from roadside and flat roof.



30. Driving over a dock-board or bridge-plate
Before driving over a dock-board or bridge-plate, be sure that it is properly secured and strong enough to sustain the weigh. Check the ground or floor condition of working area in advance.
31. Bak down and drive up
When operating loaded truck, have the rear end of your machine pointed downhill.
When operating unloaded truck, have the rear of your machine pointed upgrade.

14


32. Avoid work on a grade
Never lift loads with the truck inclined. Avoid loading work on a grade.
33. Never lift load over anyone
Never permit anyone to stand or walk under upraised forks or other attachments if machine is so equipped. If unavoidable, use a safety stand or block to prevents a possibility of fork attachments falling down or moving unexpectedly.
34. Check work ground area
Inspect the surface over which you will run. Look for holes, Drop-offs, obstacles, and look for rough spots. Look for anything that might cause you to lose control, bog down or upset.
Clear away trash and debris. Pick up anything that might puncture a tire or let the load lose balance.
Slow down for wet and slippery roads. Stay away from the edge of the road.
If ground is bumpy, it will cause the truck bump and bring much noise.
Do not operate the truck when the weather is execrable, such as windy, thunder storm, snow and ect. Especially when wind speed is higher than 10m/s, don't operate the truck outside.

35. Parking correctly
Pulling the hand brake when parking on flat.
If necessary parking on ramp, if you should place the wedges under wheels.
Descending and a little forward tilting the fork, shut off key switch and take off key.
Pull out the battery plug.
The parking place must be far away from fireworks.
36. Towing
You can tow the forklift to the safe place with towing pin when the forklift can't run.
Don't tow the truck which steering system or brake system has been damaged.

37. Nameplate
There is operate method and warning label on the truck. Please operate the truck obey the rules on the label and this manual.
Often inspect the nameplate, when damaged or lost please replace it.
38. Noise
The noise of truck is less than 75dBA, test method is use a decibel tester to record the voice 7 meters far away from truck. The decibel near operator's ear is less than 94dBA.
39. Vibration and acceleration
When unloading, operator's vibration of acceleration is about 0.74m/s2; when laden, is about 0.18/s2; so when operate on a uneven ground, it may cause more vibration for truck and operator.
 

15


Relationship between load and stability of truck
It is very important for operator to know the truck's structure and relationship between load and Stability.
 

Warning! the structure of the truck
The basic structure of the truck is mast (include mast and forks) and body (include tire).
The lift truck keeps the balance of weight between the truck body and the load on the forks with the center of the front wheels as a fulcrum when rated capacity load is placed in position.
Due care should be paid to weight and the center of gravity of loads to maintain the stability of the truck.

Warning! Load center
There is difference because of the load's shape, gravity, such as box, board roller. It is very important to distinguish the difference and the gravity center of loads.

Warning!
If the truck will turn over, do not attempt to get out of the truck, because the speed of overturn is much faster than you. You should hold the steering wheel handle, and this practice will let you in the seats.

Warning! Gravity and Stability
The combined center that is composed of the barycenter and the load center determine the stability of lift trucks.
When unloaded, the barycenter does not change.

16


Warning! the stability zone of the barycenter
In order to make the truck stable, the combined center must be in the triangle which is made up of two points that the two front wheels attach ground and midpoint of the back driving axle.
If the combined center is in the front driving axle, the two front wheels become two fulcrums, the truck will overturn. If the combined center departures the triangle, the trucks shall overturn in the corresponding direction.

Warning! Capacity chart
The chart given above shows the relation between the load center and the weight of loads.
 

17


During brake-in

We recommended operating the machine under light load conditions for the first stage of operation to get the most from it. Especially the requirements given below should be observed while the machine is in a stage of 100 hours of operation.
1. Must prevent the new battery from over discharging when early used.
2. Perform specified preventive maintenance services carefully and completely.
3. Avoid sudden stop, start or turns.
4. Oil changes and lubrication are recommended to do earlier than specified.
5. Limited load is 70~80% of the rated load.
 

 

 

 

 

 

18


Daily maintenance
You should check the truck and keep it in good condition always before starting it for safety. To assure the truck's safety is daily work and your duty.

Warning!
-except checking lights and operating capacity, you should shut off the key switch and pull out the plug before checking electric system.
-prohibit operate forklift with trouble.

-little trouble brings great accident

1.Inspect oil leakage: include hydraulic oil, electrolyte and brake fluid.
Inspect connector of the oil pipe and storage battery to see whether there is any leakage.
Use your hand to inspect, do not light a flame.
2.Inspect tire
Turn the tire valve cap counterclockwise and move it. Using a tire pressure gauge, measure the inflation pressure, and adjusting it to the specified pressure, if needed. After making sure there is no air leakage from the tire valve, reinstall the cap.

Check that each tire does not get damaged at the tread surface or side face or bending at the rim.
3. Replace tire
When the tire is damaged, you should replace it in time. Put a jack under the truck make the tire just beyond ground and put a wood block under the chassis. Loosen nut, replace new tire. Tighten the nut crossly and symmetrically.
4.Inspect torque of tire
The tighten torque of front tire is 140Nm, and rear tire tighten torque is 121-162Nm.

-Inspect the charging machine.
-Inspect every battery's polarity.
7.Charging ways: (time, current as the form)
a. 1st phase: most of the single battery's terminal voltage steps up to 2.4V;
b. 2nd phase: the electrode give off a large

 

number of buddies, the voltage and the specific gravity steadies 4 hours and the charging value gets to 4.5-5 times than rated capacity.
c. Adjusting the specific gravity and height for the electrolyte
-If the specific gravity is smaller, it will be adjusted as follow: then take out some electrode from the battery, pour the compounded sulfuric acid that is specific gravity is 1.400g/cm3
-If the specific gravity is larger, it will be adjusted as follow: then take out some electrode from the battery, pour some distilled water, but you must keep the electrode height accord with demand

d. After adjusting, you should keep charging on 1 hour; make the density of electrode even upper and under. At this time we have finished the first charging.
e. Close the pouring plug and clean the battery surface acid, then you can use it.

Warning!
During the charging, the temperature of electrode should not be exceeded 45C. Otherwise you should low the temperature. If the temperature do not lowing, you should stop recharging. till temperature drop down.

2. Daily charging
-The battery that has been made the first charging and used regular, then charged again, is named daily charging.
-Its way is almost same as the first charging.
-The recharging value is 1.2 times than the last electric discharging. But the electric-change for new battery's fore five times should be 1.5 times than the last electric discharging.
-During any charge, the temperature of electrode should not be exceeded 45C, otherwise it should be taken measure such as reducing artificially charging current or lowing the temperature. If the temperature do not drop, you should stop. charging, till the temperature dropping down.

Equalize charging
-During using the battery, it often generate the equipoise phenomena about the voltage density and the capacity.
-Individual battery's voltage and electrode compares with the most of other battery during the course of recharging, its battery's voltage and electrode specific gravity decline ahead than most of other batteries.

-Use equalize charging in the following case:

a. Discharge voltage often drop down ending voltage;
b. Discharging current value is often larger;
c. Not charging in time after discharging

d. The electrolyte is mixed with impurity of a little harm.

e. It often undercharge or do not using for a long time;
f. Take out the battery group, then check it or clean deposit.
Equalize charging way:
1. First recharge the battery normal, as finishing it, and then rest 1 hour.
2. Recharge it again by the value that belongs to the second normal recharging, until the electrode gives off a large number of bubbles, stop recharging for 1 hour.
3. Such as that and do it several times, until the voltage and the density keep fixedness and after for a while, if you recharge again, it will give off a large number of bubble.
Opportunity charging
-If a day's worth of work cannot be completed with one charging, carry out opportunity charging during breaks.
-When the temperature of circumstance is lower , carry  out opportunity charging
Charging for long-term storage

-Carry out equalize charging before storing.
-Carry out equalize charging once every 15 to 30 days during the following storage period.
