properly repaired.

1.5 Repair

Without professional training and specific authorization, the operator is forbidden to repair or change any part of
the truck. Any change of installation position of switches and safety devices is strictly forbidden by the operator
to avoid efficiency decrease of the lift table.

safety and reliability of product operation, only spare parts from manufacturer can be applied. The parts replaced,
including oils and fuels, must be disposed according to related environmental protection regulations.

 Never LIFT & LOWER the self-proplled electric lift table when

Driving

 Only be driven when lift table platform at the lowest position.

All spare parts from original manufacturer are qualified by Quality Assurance Authorities. To ensure the

1.6 Danger area

Danger area refers to the area where the lift table or its lifting device (such as fork or attachment) is working or
lifting, which brings potential dangerous factors to persons or the area for load transportation. Generally, the range
of danger area extends to the point of load lowering or truck attachment lowering.

Unauthorized persons must be kept away from danger area.

1.7 Working in hazardous environments

A self-propelled electric lift table operating in an area where there is a risk, or in any other high-risk area, should be
specially equipped for the purpose.

1.8 Safety devices and warning signs

Enough importance should be attached to safety devices, warning signs and warning notices introduced above in
Instructions Manual.

1.9 Driving in public areas

The electric lift table should not be driven on public roads outside a specific area.

1.10 Distance between vehicles

Remember that the lift table in front of you may brake suddenly therefore keep a reasonable distance.

1.11 Operation management

Driving speed must be applicable for local conditions. Low speed is requested for curve driving, narrow aisle
passing, swing door passing or driving in blocked field. The operator must be capable to measure the braking
distance to front area by sight and control the lift table continuously. Sudden brake (except in emergency), quick
U-turn and overtaking in a blocked field are prohibited.

1.12 Visibility

The operator must focus on the driving direction to ensure clear sight for the road conditions ahead. In case the
carried cargo interrupts the sight, reverse driving is requested. If it doesn’t help in this way, there must be
another person walking ahead of lift table to give guidance and warning.

1.13 Passing a slope

The permitted slope in a narrow aisle for lift table passing must be clean and anti-slip. Driving on slops stipulated
in technical specifications (instructions manual) is permitted. The carried cargo must face to upward direction of
slope. U-turning or parking this lift table on a slope is prohibited. On passing a slope, driving is requested at low
speed. At the same time, the operator must be always prepared to brake and stop.

1.14 Floor Load

It is advisable to carefully check notices and directions about the maximum floor load or maximum wheel pressure
to ensure that this is not exceeded.

1.15Transports

The self-propelled electric lift table will only be driven with the height of lift table platform to the lowest position
except when placing or removing a load.

1.16 Load characteristics

The cargo should be carried correctly, safely and reliably. Carrying a cargo with stacking-height exceeding top of
platform or protection shield is strictly forbidden.

2. DAILY INSPECTION

Daily inspection is effective to find the malfunction or faulty on the lifter. Check the lifter on the following points
before the operation.

CAUTION

DO NOT use lifter if any malfunction or faulty is found.
(1) Check scratch, bending or crack on the lifter.
(2) Check smooth movement of the wheels.
(3) Check if there is oil leakage.
(4) Check vertical creep of table.
(5) Check the function of brake.
(6) Check if all the bolts and nuts are tightened firmly.
(7) Check all the electric elements-battery indicator, horn, brake system whether to work normally
