WARNING
• Before operating a lifter, this manual must be read and understood.
• Always apply brakes to the rear wheels when loading and unloading.
• NEVER exceed the indicated max load capacity on the lifter.
• Make sure to load according to the load diagrams including y-distances. See Labels on TAWI Light
trolley and Loading on page 7-8.
• Make sure loads are distributed evenly on the platform and always load according to load diagram.
• If any unexpected movement of the lifter occurs, press emergency stop.
• In case of emergency, engage the emergency stop, see Operating panel on page 15.
• Make sure to control and solve any potential errors before resetting the emergency stop.
• The operator’s position should always be behind the lifter when it is used. From this position the
emergency stop is within reach.
• Stay clear of the area underneath a tool at all times.
• Stay clear of moving parts.
• During all service and maintenance, lay the lifter down on the oor (on its back).
• In order to deal with the lifter’s cables and wiring, a good knowledge of electricity and TAWI elec-
trical schedules of the lifters is required. Faults can cause damage to people and property.
• NEVER climb on the lifter.
• NEVER stand on the cover or any other part of the lifter.
• It must never be used to lift living humans or animals.
Caution
• The lifters are made for indoor use on a smooth, even oor/surface. Max allowed inclination is 4%.
• The recommended temperature range for the lifters is 10 - 50°C (50 - 122°F). The lifting performance
may vary when the temperature deviates from 20°C (68°F).
• Make sure there is good lighting in areas where the lifter is operated.
• Use caution when passing over thresholds, oor drains, hoses or cables.
• Never spray or pour water onto the casing containing the battery, charger and motor. Clean with a
damp cloth only.
• Recharge the battery in a designated dry area.
• Any part of this lifter or accessories that show signs of wear or other damage must be replaced
immediately. The lifter must not be used before the damaged part is replaced.
• Do not use the lifter while it is plugged into an outlet.
• Only run the lifter when it is completely assembled.
• Wear steel toe shoes with good grip when operating the lifter.
• NEVER adjust the limit switch setting on the limit switch module.

Page 06
Important
• To prevent damages and injuries caused by improper use and not to compromise the warranty and
liability: Follow the instructions in this manual at all times!
• Keep this manual accessible to all sta.
• The lifters are not intended for use by persons (including children) with reduced physical, senses or
mental capabilities, or lack of experience or knowledge, unless they have been given supervision or
instruction concerning use of the appliance by a person responsible for their safety. Children should
be supervised to ensure that they do not play with the lifters.
• Use only TAWI original spare parts.
• Always follow any local/national recommendations as well as the instructions in this manual.
• The lifter should only be used when they are in perfect working order.
• If the lifter is to be out of use for a longer period, ensure that the battery is connected to an outlet
for the charger to maintain the battert.
• Intermittent-duty: 10%.
• Emission sound pressure level: <70 dB (A).
• The lifters max load capacity has been tested with 10% dynamic overload and 25% static overload.

WEEE, RoHS and REACH
TAWI follows the WEEE (Directive 2012/19/EU), RoHS (2011/65/EU) and REACH (EC 1907/2006)
regulations.
A used battery and/or circuit board should either be returned to an authorised TAWI/Lifting Light
Trolley representative or handed over to a station for chemical waste. All other parts can be discarded
and assorted for recycling.
Do not make modications
Welding and other mechanical modications to TAWI Light Trolley or accessories must be carried out
by TAWI authorised sta. According to ISO 3691-5, only if TAWI is no longer in business and there
is no successor interested in the business, the user may perform a modication/alteration to a TAWI
Light Trolley. If this is done, the modication/alteration must be designed, tested and implemented
by experts in TAWI Light Trolley and their safety. Also, a permanent record of the design, test(s) and
implementation of the modication/alteration must be maintained. Appropriate changes to the capaci-
ty stickers, labels and user manual must be made, see Markings and labels on the TAWI Light Trolley. A
permanent and visible label must be fastened on the lifter that states how the lifter has been modied/
altered together with the date it was performed. The name and address of the organisation that per-
formed the modication must also be included.

Battery charging indicator
The color of the battery charging indicator communicates the following information:
Operating panel
Grab the handles and push the lifter to move
it forward.
To move the platform up and down push the
buttons a and c.
The emergency button is found in the middle
of the control panel, b.
• Always move the lifter with the load in a lowered position.
• If platform is lowered onto an object and is prevented from beeing lowered further down,
will belt still run. If belt hasn't fully tension there is a risk of platform falling down if object is
removed.

• Make sure that the load is stable and secured on the platform.
• Make sure the platform is loaded according to the load diagram at page 14.
• The lifter can be switched on or o when charging the battery. It is recommended that the lifter
is switched o when not in use.
• To make sure not to damage the cord when pulling it out of the electrical outlet - grab, and apply
the force to the plug. To prevent damage to the cord, never pull the cord itself always pull on the
plug.
• It is recommended to charge the battery in a full cycle.
• Never operate the lifter when the battery is charging (plugged in).
• Charge the battery in a designated dry area.
• Normal charging of the battery creates very small amounts of hydrogen. However, the casing is
ventilated, and thereby the risk of hydrogen collection is minimal.
