1 Safety information The following safety instructions apply to operation, servicing and installation. The safety instructions of the tractor and trailer vehicle remain in force. Safety instructions directly linked to the activity are listed again in the individual sections. Operating instructions for the tractor vehicle Operating instructions for the trailer BGV D8 "Accident prevention regulations for winches, lifting gear and towing equipment" BGV D29 "Accident prevention regulations for vehicles" BG "Vehicles" regulations Safety information in the following sections is shown with the warning triangle symbol. You must comply with this safety information without fail. No-one must be allowed to be under the trailer during coupling and uncoupling manoeuvres. No-one may remain under the trailer vehicle when supported. 1.2 Safety information for servicing Only use the specified lubricants for servicing work. Servicing must be carried out by skilled personnel. 1.3 Safety information for installation Landing gears must be mounted on the trailer vehicle according to the installation guidelines. If the landing gear is not installed correctly, all warranty claims against the manufacturer and the supplier of the landing gear will be rendered void. 1.1 Safety information for operation The landing gear may only be operated by authorised personnel. The landing gear may only be operated if the trailer vehicle has been secured to prevent it rolling away. When releasing the crank, remember that it may recoil. Low or high gear must always be engaged. When the trailer vehicle is in motion, always place the crank in the crank mounting. The crank must always be installed. When the vehicle is in motion, the landing gear must be fully retracted. When supporting the vehicle, ensure that the ground is sufficiently firm and/or position a suitable base underneath. When supporting, the supporting feet must be freely mobile or the castors must be able to spin. The function area of the foot must be clear and flat. Do not support landing gear, e.g. in order to even out height differences. Do not exceed the upper or lower lifting limit of the landing gear. Driving with damaged landing gear is forbidden. Repair the landing gear or remove it as necessary. 14 ZDE 199 006 052 06/2010 Landing gear module

The gear must engage. Remove the crank from the parking hook and push in until the gear engages. A slight turning motion will facilitate gear change. The gear must engage. Disconnect the tractor vehicle (see "Tractor" and "Towing device" owners manuals). Hook the crank into the crank holder. The disconnected trailer must not be moved, even with the "R-foot". 3.2 Disconnecting the semi-trailer 3.3 Connecting the semi-trailer When you have finished turning the crank handle, slowly relieve the strain on the crank. There is the risk of recoil by the crank. Engage low gear and adjust the coupling height (see "Tractor vehicle" and "Towing device" owners manuals). Completely retract the landing gear after hitching up. Hook the crank into the crank holder with a gear engaged. 1 3.4 Loading the supported trailer JSK-ST/09 When you have finished turning the crank handle, slowly relieve the strain on the crank. There is the risk of recoil by the crank. Do not exceed the full lifting travel. The supported trailer is allowed to be loaded providing the appropriate safety regulations are complied with. The permitted loading work involves: Loading with a crane Loading with a forklift. Do not exceed the centre of gravity otherwise the trailer will tip. Park the trailer on firm, flat and level ground (see the "Trailer" owner s manual). Put a suitable base (1) underneath the landing gear if necessary. Check the landing gear for damage and have any damage repaired before use. Engage high or low gear and wind down the landing gear. Change over from high gear to low gear before the foot makes contact with the ground. 16 ZDE 199 006 052 06/2010 Landing gear module
