Page 4: Safety
Failure to follow the instructions of this manual can lead to unpredictable hazards. For any resulting damage or personal injury, HADEF assumes no liability. The unit was designed and built following a risk analysis and careful selection of the harmonized standards that are to be complied with, as well as other technical specifications. -
Page 5: Requirements For The Operating Personnel
Devices for use in area prone to explosion must (from customer's side) be earthed with a shunting resistor of < 10 Ω against earth. WARNING! It is not allowed to make constructive changes of the equipment! Requirements for the operating personnel The units may only be operated by qualified persons that are appropriately trained and that are familiar with it. -
Page 6: Basic Safety Measures
Basic safety measures Observe installation-, operation and maintenance instruction. Take notice of caution notes at units and in the manual Observe safety distances. Take care for a free view on the load. Only use the hoists appropriately. The equipment is to be used exclusively for movement of goods. Under no circumstances my persons be moved. -

Page 12: Functions
Illustration 3 Illustration 2 Functions The load is lifted or lowered by pulling one of the chain falls of the endless hand chain of the hoist. A load pressure brake prevents automatic lowering of the load after releasing the hand chain. In combination with hand geared trolleys, the trolley is moved to the left or to the right side by pulling the hand chain. -

Page 17: Load Chain
Load chain Before commissioning the load chain must be aligned and oiled. Move safety note and fixing wire away from the chain. CAUTION! Do not use grease for lubrication of load chain. Without lubrication, manufacturer's warranty and/or liability will be void. NOTICE! Continuous, thorough lubrication will increase the life of the chain considerably. -
Page 18: Replacing The Load Chain
11.3 Replacing the load chain CAUTION! If there is any visible damage and when the conditions for replacement are reached (i.e. one or several dimensions in the table have been reached, there is corrosion or elongation), the chain must be replaced. When replacing the chain, also check the chain wheels. -
Page 19: Checking The Load Chain
WARNING! If one or several of the dimensions fall below or exceed the dimensions in the table, or if cracks or corrosion are found, the parts must be replaced with original spare parts. 12.2 Checking the load chain CAUTION! The load chain must be tested over its entire length! The measure of the load chain must be carried out especially in the areas which are subject to the highest wear. -
Page 20: Checking - Pawl
CAUTION! When the dimension of hook opening width is deformed more than 10% or when the dimension of the hook bottom thickness is fallen short of by 5% due to wear, the hook must be replaced. DANGER! In case of corrosion and/or wear of the surface coating, the hooks must be exchanged by original hooks or the coating must be renewed. -

13.6 Gear spring pressure brake During the check, brake lining wear is verified. The brake linings must be replaced when the wear limit is already reached at one position of the lining, - as this can be the case when wear of the linings is irregular. CAUTION! The brake linings must be free from fracture. -
