Security instructions

Keep your work area dry and tidy! An untidy work area may cause accidents. Avoid slippery floor.

•  Make sure the work area is lighted sufficiently
•  Always stay focused when working. Reduce distortion sources in your working environment. The operation of the machine when being tired, as well as under the nfluence of alcohol, drugs or concentration influencing medicaments is forbidden.
•  Only one person shall operate the machine.
•  The machine must be operated only by trained persons (knowledge and understanding of this manual), which have no limitations of motor skills compared with conventional workers.
•  Make sure there is nobody present in the dangerous area. The minimum safety distance is 10 m
•  Use personal safety equipment: safety shoes S1, work wear when working with or on the machine!
•  Never leave the machine running unattended! Before leaving the working area switch the machine off and wait until the machine stops.
•  Always disconnect the machine prior to any actions performed at the machine!
•  Do not use the machine with damaged switch
•  The plug of an electrical tool must strictly correspond to the socket. Do not use any adapters together with earthed electric tools
•  Each time you work with an electrically operated machine, caution is advised! There is a risk of electric shock, fire
•  Protect the machine from dampness (causing a short circuit)
•  Check the cable regularly for damage
•  Do not use the cable to carry the machine or to fix the load
•  Protect the cable from heat, oil and sharp edges
•  Avoid body contact with earthed components
•  Keep any machine that is not being used out of reach of children

ASSEMBLY

Please check the product contents immediately after receipt for any eventual transport damage or missing parts. Claims from transport damage or missing parts must be placed immediately after initial machine receipt and unpacking before putting the machine into operation. Please understand that later claims cannot be accepted anymore.

OPERATION

Machine to be operated in a perfect state only. Inspect the device visually every time it is to be used. Check in particular the safety equipment, electrical controls, electric cables and screwed connection for damage and if tightened properly. Replace any damaged parts before operating the device.

Operation instructions

• In particular, check the perfect state of the snap hooks preventing any unintentional release of the lifting hook from slings (ropes, rings, transportation eyes, etc.).
•  All lifting work is only allowed when appropriate fixing elements (ropes, rings, transport loops, etc.) are used and when in accordance with appropriate provisions and standards valid in the workplace.
•  The machine can only be used for lifting of loads whose weight does not exceed the maximum payload specified by the producer in technical data and on the type label of the machine.
•  Attach the load correctly.
•  Lifted loads may only be lifted in a vertical position! Never pull and lift in an inclined position!!
•  The steel rope must not be used for load fixing.
•  When using the deflection pulley, hang the lifting hook into the hook holder of the carrier housing.
•  Check, whether the emergency switch (11) is pressed. For unlocking, turn the emergency switch (1) clockwise.
•  For lifting the load, press the up-down-switch ▲ (10).
•  For lowering the load, press the up-down-switch ▼ (10).
•  The machine is provided with up limit switch and down limit switch, which prevent that the steel rope is completely or wrongly unwound and/or the load is lifted up too high. Never totally unwind the rope. At least 2 windings of the rope must remain on the drum!
•  In the emergency case press the emergency switch (11) immediately. The machine stops.

Use with deflection pulley

•  The machine is provided with a deflection pulley and hook. When they are used correctly the machine can lift double payload.
•  Mount the deflection pulley as shown on the below picture.
•  When using the deflection pulley, hang the lifting hook into the hook holder of the carrier housing. With help of 2 steel ropes to lift the load the machine is now capable to lift the double load.
  

MAINTENANCE

Check regularly the condition of the security stickers. Replace them if required. Check regularly the condition of the machine! Store the machine in a closed, dry location.

•  Check regularly the correct function of the limit switches and the emergency switch.
•  Per 30 cycles check the condition of the steel rope. If there are any damages replace the steel rope in accordance with the technical details.
•  Per 200 cycles lubricate the steel rope and the deflection pulley.
•  Per 1000 cycles check that the screws of the mounting brackets are well tightened
•  Per 1000 cycles check that the hook and the deflection pulley are in good condition.
•  Per 1000 cycles inspect the braking system. If there are abnormal noises in the motor or the machine is unable to hold the payload the braking system must be checked. Per cycle means that the operator operates the load up and down for one time.

Cleaning

The usage of certain solutions containing ingredients damaging metal surfaces as well as the use of scrubbing agents will damage the machine surface! Never spray water on the machine or submerge it to any liquid.

Disposal

Do not dispose of the machine in residual waste. Contact your local authorities for information regarding the available disposal options. When you buy at your local dealer for a replacement unit, the latter is obliged to exchange your old.
