I.Driving Operation and Daily Maintenance of Forklift Truck
It is important that driving and managing persons for forklift trucks remember
the principle of the“first safety”and ensure the safety operation as the description of
《Operation and Service Manual》.
1. Transport of Forklift Truck
Pay attention to the following items when you transport forklift trucks with
container or trucks:
(1)Apply the parking brake.
(2)Fix the mast and the balance weight with steel wire. Wedge up all wheels.
(3)Sling points should be always at the positions specified in sling index plate
when hoisting up the forklift truck.
2. Storage of Forklift Truck
(1)Drain off fuel completely. Don't drain off the cooling water containing
antifreeze and rustproof agent.
(2)Apply antirust to the surface of the parts not painted. Apply lubrication oil to
the lift chain.
(3)Lowing the mast to the lowest position.
(4)Apply the parking brake.
(5)Wedged up the wheels.
3. Precautions before Operation
(1)Don't check fuel leakage and level or instruments at the place there is open
flame. Never fill the fuel tank with the engine running.
(2)Check the tire inflation pressure.
(3)The forward-reverse lever should be in neutral.
(4)Never smoke while the fuel system is under working or the battery is
inspected.
(5)Check all the levers and pedals.
(6)Complete the provisions before starting.
-1-
(7)Release the parking brake.
(8)Make trial of the mast for lifting, lowing and forward and backward tilting
and the truck for steering and braking.
(9)The contamination level of the hydraulic oil should be lower than 12 as
described in NAS 1638.
4. Operation of Forklift Truck
(1)Only trained and authorized operator shall be permitted to operate the truck.
(2)Wear all the safety guards, such as shoes, helmet, clothing and gloves while
operating the truck.
(3)Check all the control and warning devices before staring the truck. If any
damages or defects are found, operate it after repairing.
(4)The goods handled should not exceed the rated capacity of the truck. Insert
forks deeply under goods and make the loads distribute on the forks evenly. Don't pick
the loads with one fork tip.
(5)The starting, turning, driving, braking and stopping of the truck should be
done smoothly. When steering on the humid or low friction road, the truck should be
decelerated.
(6)Travel with loads as low as possible and tilted backward.
(7)Be careful when traveling on a slope. When climbing grade with a slope more
than 10%, the truck should travel forward, and when descending so grade, backward
travel. Never turn on a slope. Avoid loading and unloading operation when
descending.
(8)Pay attention to pedestrian, obstacle and bumpy road when driving. Pay
attention to the clearance over forklift truck.
(9)Never allow any person(s) to stand on the forks or the truck to carry person.
(10)Never permit anyone to stand or walk under upraised forks.
(11)Don't operate truck and attachment at any position out of the driver seat.
(12)On the high lift forklift truck with the lift more than 3m, it is noted that the
-2-
goods on it should not fall down or the protection measures be taken if necessary.
(13) Tilt the mast of the high lift forklift truck as backward as possible when the
truck works. Use minimum forward and reverse tilt when loading and unloading.
(14)Be careful and slowly driving over a dockboard or bridge-plate.
(15)Shut down the engine and don't stay on the truck when filling fuel. Don't
ignite the engine when checking battery or fuel lever.
(16)The unloaded forklift truck with attachment(s) should be operated as a
loaded truck.
(17) Don't handle unfixed stacked goods. Be careful to balky goods to be
handled.
(18) When leaving lower the forks on the ground and let the shift lever to neutral,
shut down the engine or cut down electric supply. If parking on a grade is unavoidable
apply the parking brake and block the wheels.
(19) Don't open the radiator cap when the engine is warm.
(20) Don't adjust the control valve and relief valve at will to prevent the damage
of hydraulic system and its components because of excessive pressure passing them.
(21) Tyres should be inflated according to the pressure valve specified in the
mark plate of “Tyre pressure”.
(22) According to the measure method specified in JB/T 3300. Max. noise at the
outboard of the truck should be not more than 89dB(A).
5. Cautions on Cooling System
Cooling system which is filled with HELI exclusive coolant free from
maintenance normally before leaving the factory is used to cool engine and hydraulic
powered transmission unit (hydraulic powered type forklift truck). The coolant filled
in the truck can not only protect the truck against freezing above -35℃, but also
protect the cooling system from corrosion, scale-forming and increase the coolant
boiling point remarkable. So the coolant concentration will not be reduced even in the
warm season or area because of water replenishing. If greater anti-freezing protection
-3-
is needed considering climate, please contact with local HELI sales network for HELI
exclusive coolant with greater anti-freezing ability.
(1) If the radiator appears “boiling” or excessive coolant temperature, it is
prohibited strictly to open the radiator cover immediately. Do as the following:
(a) Park the truck at a safe area;
(b) Keep the engine idling and open the engine hood to keep good ventilation;
(c) Shut off the engine when the water temperature indicator points to the normal
range;
(d) Check the following points when the engine is cool completely:
● Check if the coolant lever is correct;
● Check if the fan belt is loose;
● Check the engine oil quality and oil level;
● Check if the radiator is clogged;
● Check if the thermostat can open normally;
(2) Use HELI exclusive coolant in order to keep the engine and cooling system
in good condition. Change it once a year. If the coolant is bad in less than one year,
change it when necessary. When changing the coolant, clean the interior of the cooling
system. The freezing point of the coolant should be at least 10℃ lower than the lowest
environment temperature.
(3) Replenish the coolant with HELI exclusive one only when the engine is cool
when necessary avoiding engine damage. If there is no HELI exclusive coolant in an
emergency, never add any additives. Add water only and contact with local HELI sales
network for proper mixture as possible. Use new HELI exclusive coolant when
replenishing. It is prohibited to add hard water such as tap water, mineral water, river
water, well water to the cooling system avoiding radiator corrosion or scale forming
which will reduce radiator performance and service life.
(4) It is prohibited to contact the radiator core directly with sharp hard objects if
the core is dirty. Clean it with water flow or air flow with the following set pressure
-4-
value. Keep the mouth against the radiator core.
Water flow pressure: no higher than 0.49MPa (5kgf/cm²);
Air flow pressure: no higher than 0.98MPa (10kgf/cm²).
(5) Coolant storage notes:
(a) Avoid direct contact with the coolant which is bad for health;
(b) Store the coolant in proper sealed container because the coolant steam is
harmful. Make sure to keep it out of the reach of children because there is a danger of
poisoning;
(c) Once the coolant goes to eyes, please wash with water and see a doctor;
(d) See a doctor immediately once the coolant is drank carelessly;
(e) Never use the coolant drained from the truck again. Place the coolant drained
from the truck in a special container and deal with environmental rules.
