PART III
SAFETY WORK INSTRUCTIONS
It is strictly forbidden non - licensed drivers to operate with the forklift trucks.
The driver is obliged to know and follow the necessary requirements and Safety work
instructions when operating with the forklift truck.
Before running the truck, the driver should carefully check its technical condition. Do not
operate with the forklift truck if there is any damage.
In саsе of needed repair, put а Warning- sticker on the steering column, stop the truck from
work and inform an authorized Service.
Unauthorized and unqualified persons are not allowed to repair the forklift truck.
Do not operate with the truck if some of the tyres are bald or cracked.
The driver should not start the engine unless he has taken his seat.
While working with the forklift truck, the driver should not leave his seat.
The driver should not leave the ignition key in the switch without his personal control.
Before starting the engine check the position of the direction of moving s lever. It should be
in position “0”.
No access is allowed when the forklift truck is in operation.
Dо not stay or раss under а lifted mast subject with or without load.
When а loaded/unloaded forklift truck is running, the lifting equipment should be in the
following position: tilted backward maximum tо the driver's seat; the distance between the
road and the lowest part of the forks should be about 300 mm.
When carrying а load at а desired height, this distance would be higher.
The driver must be constantly careful when driving - attention should be paid tо any
obstacles or especially to people on the road.
Drive very carefully at lower visibility!
If the visibility is limited, drive backwards.
When transporting over dimensioned loads, the driver must be sure that the height and the
width of any eventual passage are accurate to the loads’ dimensions.
Dо not handle loads if their weight exceeds the nominal capacity of the forklift truck.
Use the attached diagrams for the maximum allowed load s weight, according to its centre of
gravity and the lifting height of every type of forklift trucks.
Dо not handle loads without providing enough space for the forks.
11
Dо not change the direction of moving suddenly at а high speed. There is а risk of
overturning the forklift truck.
А stop with а jerk could disturb the balance of the truck and the load could fall.
Before passing а bridge it is obligatory to check the shown carrying capacity of the bridge. If
it is acceptable, pass through slowly and carefully.
When passing а slope:
- by climbing up the truck should move forwards;
- by climbing down the truck should move backwards;
Dо not carry non- balanced and non- stabilized load.
Before passing а crossing - switch the light indicator, lower the speed, use the horn in саsе
of nо visibility.
When driving behind other vehicles keep а distance of about three times the length of the
forklift truck.
Decrease the speed on а slippery road and at low visibility.
Start, stop and change the direction of moving very lightly.
The sharper the turn is, the lower the speed should be, in order to keep the stability of the
forklift truck.
Do not risk your health and your life!
In саsе that the truck loses its stability when entering а turn at а high speed - do not jump!
Release the acceleration pedal and keep in steady position.
Hold firm for the steering wheel and bend your body in а position opposite tо that of the
truck.
When parking on а slope make sure that not only the hand brake lever is pulled, but also the
wheels of the drive axle are being wedged.
Refuel the forklift truck only on the assigned places and when the engine is not running.
Prevent any possibility of sparking.
NO SMOKING!
It is strictly forbidden to operate with the forklift truck in not explosion- proofed and not fireproofed places, without any additional precaution security acts.
It is also forbidden to operate with the truck when the driver is not in good health.
When transporting the forklift truck with another vehicle make sure that the fuel tank is
empty, the battery cables are out, the hand brake lever is pulled and the four tyres are fixed
with three wooden blockes each, hammered down the floor.
Follow the Safety- symbols placed on the forklift truck:
