INTRODUCTION Read through all of the instructions before starting installation. Notifications and warning texts are for your safety and to minimise the risk of something breaking during installation. Ensure that all tools stated in the instructions are available before starting installation. Certain steps in the instructions are only presented in the form of images. Explanatory text is also given for more complicated steps. In the event of any problems with the instructions or the accessory, contact your local Volvo dealer. General guidelines 1 General guidelines For safety reasons, when using RUD-comfort centrax type chains, the recommended speed limit of 50 km/h must never be exceeded. In some countries this speed limit may be even lower. This should be respected The driving characteristic of cars with snow chains are different!braking distances are increased on roads clear of snow or ice Always adapt your driving to the road conditions! The chains must only be used in pairs on the driving wheels The car must not be driven if the snow chains are not correctly installed. Ensure that the chain is evenly mounted over the entire wheel. The tension of the chain is correct if it can be lifted approximately 1.5 cm from the tyre. If the chain is incorrectly positioned (if it is too loose for example, it may knock against other parts of the vehicle. Check if the chain is correctly positioned and adjust the tension if necessary R7700442 After driving longer stretches, the chains should be checked to ensure that they are still correctly positioned The air pressure listed by the manufacturer also applies when using snow chains RUD-comfort centrax snow chains have been developed to improve the grip and braking capacity of the drive wheels (on snowy or icy road surfaces). They are not intended for any other usage Avoid heavy acceleration and wheel spin which cause considerable wear to the chains Remember that the service life of the chains is fully dependent страница 4 / 15
on the way in which you drive. Careful driving will increase the service life of the chains Care instructions:clean the chains using hot water. Dry the chains thoroughly after each usage. Never treat the chains with oil! The chains are manufactured from high quality steel. However they have not been rust-proofed. Minor rust does not affect the quality of the chains Snow chains such as RUD-comfort centrax are an important part of the safety equipment for winter driving. Always follow these instructions carefully to ensure many years of use from your chains and to ensure you arrive at your destination safely. We accept no liability for personal injury or material damage, such as damage to the chains, if these instructions have not been followed Always follow the car manufacturers instructions about the use of snow chains in the owner's manual supplied with your car. This also applies to four wheel drive vehicles Before setting off, you should check your RUD-comfort centrax chains and ensure that they are correctly positioned. First of all check that the tyre size given on the packaging matches the tyre dimensions of your car. Warning: the codes must be exactly the same. There is a considerable difference between, for example, 225/60 R 16 and 225/55 R 16! RUD-comfort centrax chains have been developed to suit tyre dimensions for summer and winter tyres according to DIN and ETRTO If it is not possible to obtain the correct size and fit of snow chains (see the instructions), they should not be used. If this is the case, please contact your dealer Follow these instructions closely. If these instructions are not followed, there is a risk of damage to the snow chains or the car. This could also increase the risk of an accident Check the chains each time they are installed on the tyres. If the chains are more than 50% worn, or if a link has broken, the chains should not be used. If this should happen, send the chain to the manufacturer for repair. If a link has broken, the chains must be removed immediately to prevent damage to the car Only the manufacturer should carry out repairs to the chains. Other repairs will invalidate the separate warranty. Snow chain components 2A Snow chain components Illustration A 1 = arm 2 = lever 3 = safety release страница 5 / 15

A7700196 5 Applies to cars with steel rims or hub caps on lightmetal alloy rims Remove the hub caps. A7700197 Installing the snow chains Note! The snow chains must only be installed on the front wheels. All operations must be carried out on both the front wheels 6 Press a suitable adapter (A) into place on the wheel Tighten the adapter. Tighten to 70±5 Nm (52±3.7 lbf.ft.). Use a torque spanner or a socket set. Note! Do not use impact drivers. Ensure that the adapter is securely installed. страница 7 / 15
A7700198 7 Open the safety catches Position the chain on the wheel. R7700454 8 Pull the lever past its catch position. The lever will secure in this position. R7700466 9 Press in the yellow button (A) on the mounting arm (B). Adjust the handle on the mounting arm so that it is pointing towards the centre of the hub. Note! The mounting arm must be installed in this way. страница 8 / 15
Press the mounting arm on to the adapter until the catches engage. Note! The yellow button must spring back to its original position. R7700465 Ensure that the catches are secure on the adapter. Adjusting the tension of the chain 10 Adjusting the tension of the chain Tighten the tensioner strap until it is fully tensioned between the housing and the mounting arm. The quick-tensioner locks the strap in the tensioned positioned. Note! The inset picture shows the correct strap tension. R7700467 11 Thread the end of the tensioner strap through the girdle (A) and through the housing following the markings. R7700461 12 страница 9 / 15
Close the lever. R7700450 13 Press the safety catches to the locked position. R7700451 14 Drive forward or backwards carefully so that the chains pulls itself up onto the wheel. Note! If installing when on an incline; drive downwards if possible. R7700469 страница 10 / 15
15 The tensioner strap must be tensioned when the chain net is in place. Check the tension of the tensioner strap. If the tensioner strap is still loose, tighten it further. See points 10-13. R7700449 Adjusting the chain net 16 Adjusting the chain net There must be play of approximately 15 mm (9/16 ) between the surface of the tyre and the chain net. Check the distance between the surface of the tyre and the chain net. If the clearance exceeds 15 mm (9/16 ), shorten the chain net. See points 17-19. Otherwise proceed to point 20. R7700462 17A Illustration A Illustration B The shortening points (open chain links) are beside the stud elements. Illustration C Use the bar from the socket set as a lever to pry up the open chain links страница 11 / 15
Remove the chain net from the stud element. R7700452 17B R7700453 17C R7700457 18A Illustration A Shorten both the chains by one link. Note! The chain net must only be shortened by one chain link at each shortening point. Both of the chains must be the same length. Illustration B страница 12 / 15
Hook the chain net back on to the stud element Jerk the shortened chain down to its original position If necessary, press the shortened chains into the stud element by hand. R7700460 18B R7700459 19 Drive approximately 100 m (109 yds). Then check the length of the chain net again. Removing snow chains 20 Removing snow chains Open the safety catches.
