The “Guidelines for the Correct Use and Application of Industrial Trucks” (VDMA) are
supplied with the truck. The guidelines form part of these operating instructions and
must be observed. National regulations apply in full.
The truck described in the present operator manual is an industrial truck designed for
lifting and transporting load units.
It must be used, operated and serviced in accordance with the present instructions.
Any other type of use is beyond the scope of application and can result in damage to
personnel, the truck or property. In particular, avoid overloading the truck with loads
which are too heavy or placed on one side. The data plate attached to the truck or the
load diagram are binding for the maximum load capacity. The industrial truck must not
be used in fire or explosion endangered areas, or areas threatened by corrosion or
excessive dust.
Proprietor responsibilities
For the purposes of the present operator manual the “proprietor” is defined as any
natural or legal person who either uses the industrial truck himself, or on whose behalf
it is used. In special cases (e.g. leasing or renting) the proprietor is considered the
person who, in accordance with existing contractual agreements between the owner
and user of the industrial truck, is charged with operational duties.
The proprietor must ensure that the truck is used only for the purpose it is intended for
and that danger to life and limb of the user and third parties are excluded.
Furthermore, accident prevention regulations, safety regulations and operating,
servicing and repair guidelines must be followed. The proprietor must ensure that all
truck users have read and understood this operator manual.

2.Transport and Commissioning
2.1Transport
Lifting the truck by crane
There are two way to pack the truck: on
e
is use a stock, the other is use a box. Th
e
way to pick up depend on transport.
1.Only use crane handling equipmen
t
gear with sufficient capacity.
2.Loading weight > net weight of truck (
+
battery weight for electric trucks).Loading
weight not only net weight of truck bu
t
also the stock or the box.
3.Stock (box) should be big enough and
strong enough to bear hole truck.
– Park the truck securely.(see 3.2.4
Parking the truck securely on page 21).
–Make sure forks are positioned properl
y
for the pallet. Move forward slowly t
o
insert forks into the pallet as far a
s
possible and then stop the truck.
2.2Using the Truck for the First Time
Only operate the truck with battery current. Rectified AC current will damage the
electronic components. Cable connections to the battery (tow leads) must be less
than 6 m .
Preparing the truck for operation after delivery or transport
Procedure
–Check the equipment is complete.
–Check the hydraulic oil level.
–Install the battery if necessary (where required), (see "4.4 Battery removal and
installation" on page 24) do not damage battery cable.
–Charge the battery, (see "4.3 Charging the battery" on page 23).
When the truck is parked the surface of the tyres will flatten. The flattening will
disappear after a short period of operation.
Warning
–To avoid break the fork be hurt when you move the truck to stock.
–In order to keep the truck out of be scraped,please move the truck void in
void and flat place.
– when you lowering the stock advert status of the place to avoid collapse.

2.3During 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. Please
charging when remain power less than 20%.
2. Perform specified preventive maintenance services carefully and c.ompletely.
3. Avoid sudden stop, starts or turns.
4. Oil changes and lubrication are recommended to do earlier than specified.
5. Limited load is 7080% of the rated load.
