INSTRUCTION HANDBOOK Electric Lifting Table
Foreword
Before operating the lifting table, read this ORIGINAL INSTRUCTION HANDBOOK carefully and understand the usage of the lifting table completely. Improper operation could create danger. This handbook describes the usage of different lifting tables. When operating and servicing the lifting table, make sure, that it applies to your type. Keep this handbook for future reference. If this or the warning/ caution labels are damaged or got lost, please contact your local dealer for replacement.
ATTENTION:
- Environmentally hazardous waste, such as batteries, oil and electronics, will have a negative effect on the environment, or health, if handled incorrectly.
- The waste packages should be sorted and put into solid dustbins according to the materials and be collected disposal by local special environment protection bureau. To avoid pollution, it's forbidden to throw away the wastes randomly.
- To avoid leaking during the use of the products, the user should prepare some absorbable materials (scraps of wooden or dry duster cloth) to absorb the leaking oil in time. To avoid second pollution to the environment, the used absorbable materials should be handed in to special departments in terms of local authorities.
- Our products are subject to ongoing developments. Because this handbook is only for the purpose of operating / maintaining the lifting table, therefore please have understanding, that there is no guarantee out of particular features out of this handbook.
NOTE: On this manual, the left sign means warning and danger, which can lead to death or serious injury if not followed.

1. Correct Application
It is only allowed to use this lifting table according to this instruction handbook. This table is a mobile lifting table designed to lift or lower a clearly defined load. Do not use this table for other purpose than its intended use. A wrong usage can cause human injuries or can damage equipment. The operator/ the operating company has to ensure the correct usage and has to ensure, that this table is used only by staff, which is trained and authorized to use this table. The table has to be used on substantially firm, smooth, level and prepared surfaces. Driving with the load lifted is not allowed. The load must be placed approximately on the longitudinal centre plane of the table. The capacity is marked on capacity sticker as well on the Identification plate. The operator has to consider the warnings and safety instructions. The table is intended to be used for indoor applications with ambient temperatures between +5°C and + 40°C. Operating lighting must be minimum 50 Lux.
Modification
No modifications or alterations to this lifting table which may affect, for example, capacity, stability or safety requirements of the truck, shall be made without the prior written approval of the original truck manufacturer, its authorized representative, or a successor thereof. This includes changes affecting, for example braking, steering, visibility and the addition of removable attachments. When the manufacturer or its successor approve a modification or alteration, they shall also make and approve appropriate changes to capacity plate, decals, tags and operation and maintenance handbooks.
By not observing these instructions, the warranty becomes void.

Place the table at a safe place, if possible/necessary activate the safety mechanism (14) against lowering, park the table on a safe area by activating the parking brake (7) and lock the lifting table with the key (12). Inform immediately the manager and, or call your service. Start operating the table only if the reason for the malfunction was investigated and repaired.
g. Emergency
In emergencies, push the emergency button (11). All electrical functions will be stopped. Keep safe distance. If possible activate the parking brake.
7. Charging the Battery
⚠️ It is only allowed to use the in this chapter specified batteries.
These batteries are maintenance free; re- filling is prohibited.
Recycling of batteries undergoes national regulations. Please follow these regulations.
⚠️ By handling batteries, open fire is prohibited.
⚠️ In the area of battery charging neither burning materials nor burning liquids are allowed. Smoking is prohibited and the area must be ventilated.
The charger (9) is especially developed for the use with this lifting table. It offers automatic detection and tracking of the battery, until the charging is automatically completed.
The lifting table is equipped with “maintenance free” sealed liquid acid batteries.
- ETF 30/ ETF 75/ ETF D35: 4 x 12V 15 Ah / Type BT-12M15AC
- ETF 50: 2 x 12V 24 Ah / Type BT-12M24AT
a. Installation and Removal
Install the batteries to the lifting table by opening the cover and inserting the batteries carefully. Prevent to have short-cuts during the installation. Fix the connectors accordingly and consider the right connection of the battery poles. Finally assemble the cover. The removal is in the opposite direction.
b. Charging
The attached automatic charger is only available for the optional voltage of 110V or 220V as referred.
Check the wiring or confirm AC voltage when AC power Indicator of the charger shows abnormal by red flashlight.
Charging is necessary, if the battery voltage is lower than 9,6V. The voltage is shown on the voltmeter (10).
Turn off the lifting table by turning the key switch (12) to the "off"- position.
Connect the charger (9) with the included cable to the power socket.
Charging starts automatically.
The switch of charger turns off automatically, if the battery reaches 80% capacity or exceeds 12 hours in charging condition.
Disconnect the charger with the power socket and store the charging cable for further charging-operations.
The charging indicator (13) shows the charging voltage, the connection to the battery (battery-symbol is lighting), the charging-function (Power-symbol is lighting) as well as the finished charging (full-symbol is lighting).
Fig. 7: Charger illustration.
8. Regular Maintenance
⚠️ Only qualified and trained personnel are allowed to do service on this lifting table.
Before servicing the table, remove the load and during servicing use the safety mechanism (14).
If you need to lift the table, remove the battery and use designated lashing equipment. Before working, put safety devices (for instance designated lift jacks) under the table to protect against accidental lowering.
Use approved and from your dealer released original spare parts.
Please consider that oil leakage of hydraulic fluid can cause failures and accidents.
It is allowed to adjust the pressure valve only from trained service technicians.
If you need to change the wheels, please follow the instructions above. The castors must be round and they should have no abnormal abrasion.
- Remove load from table and when servicing lifter, please use safety stopper to prevent table from lowering.
- Check the items emphasized in daily inspection (daily).
- Lubricate with grease the rails where roller moves. Also lubricate the grease nipples (monthly).
- Lubricate all the pivoting points and axles (every 6 months).
- Replace the hydraulic oil (every 12 months).
The required hydraulic fluid- type is:
- YA-N46
- viscosity is 41.4-50.6
- amount 2,5L
For refilling the hydraulic fluid, you need to unscrew the hydraulic power pack and place this vertically. Then you can remove the oil tank and it is possible to check and refill the oil. Assembling must be done in the opposite direction. For this work please call the service.
If you need to replace the hydraulic hoses, use only dedicated original parts according to the spare parts list.
Waste material like oil, used batteries or other must be probably disposed and recycled according to the national regulations and if necessary brought to a recycling company.
Before starting operating the lifting table check, if all markings and decals are in the right place and not damaged (acc. to chapter 2 c ). If necessary replace the decals. If major repair or replacement to a load supporting member of the lifting table has been carried out, following tests needs to be carried out. For this you need to have special skills.
⚠️ FOR THIS PLEASE CALL YOUR NEXT DEALER OR SERVICE!
