Fasten the links on the outer side the locking block to secure. chain with the pin-shackles. 15
Pic 7.6 Pic 7.7 7. Tighten the inner side chain with the pin-shackles by removing 1 pin and 1 link of side chain. See Pic 7.6 Attach 1 pin shackle (plug coupler) to both rings for tightened fit. See Pic 7.7 Fasten and secure all forgings with the connecting ring (part A07). Fasten the left and right chain side, Close the centre chain with pin-shackle or shackle. See Figure 7.8 Figure 7.8 16
Pic 8.0 Pic 8.1 Secure the installation tool (cable come-along) at appropriate position as shown. See Pic 8.1-8.3 Pic 8.2 Pic 8.3 17
Pic 9.0 7. Drive until the pattern connection point is at the very top of the tire. Remove the mounting chain. Secure the cable style tightener at appropriate position, (see pic 8.o) then tighten the tensioning chain. Adjust the tensioning chain rings with a hammer allowing easy chain travel through the rings. 18
Pic 10.0 1. Adjust the tensioning chain until the TPC chain fits snugly on the tire. To fasten the tensioning chain, push the locking plate around the tensioning chain and fasten. This is done while the installation tool is still keeping tension on the tensioning chain. See pic 10.1 Pic 10.1 19
2. Mount the locking plate to lock the tensioning chain, to avoid the tensioning chain from drawing back. 3. Remove the tightener; fasten tensioning chain ends with a chain-shackle. Repeat tensioning procedure (as in step 8-10) after driving backwards and forwards a number of times. Remove the installation tool if used; fasten tensioning chain end with a chain-shackle. See Pic 10.2 Pic 10.2 20
Pic 11.0 TPC correct fit. Drive the vehicle forward and backward in a straight line until the chain is correctly centered. That is achieved when the inner chain and tensioning chain are parallel with the rim and with an equal spacing between. (to the best of your ability) Repeat Step 8 to 10 if needed, to ensure chain is installed correctly. 21
Pic 12.0 Correct chain tension The chain is correctly tensioned if the forged links on the face of the tire can be slightly tilted and the tensioning chain can still be slightly pulled off the wheel by hand. On soft underground it is recommended to relieve the chain tension in order to improve grip and self-cleaning of the Chain. 22
1. Altering of inner chain Lengthening (a): With extension piece and two pin-shackles Shortening (b): Remove three links, fasten with one pin-shackle Figure 12.1 2. Altering the whole chain, if altering of the inner chain is insufficient. Lengthening: build in extension piece X with connecting rings (mechanical rings). See Pic 12.2 Shortening: remove the extension piece X by removing the connecting rings. See Pic 12.3 Do not heat the neighboring rings during oxy/acetylene, plasma, etc. cutting, as loss of hardness is possible. 23

Check chain fitment and tension regularly. After a certain period of operation when the chain becomes loose it is necessary to retighten by adjusting the tensioning chain- refer to: Step 8 - Step 12 25
Repair the chain immediately with Quality Chain spare parts in order to not cause more damage to the chain. Original Quality Chain spare parts fully replace damaged chain parts thus maintaining chain life as well as tire protection. Replacement of worn down forgings by pin-shackle (plug coupler) Figure 12.4 Replacement of worn down TPC pattern rings with connecting rings, (mechanical repair rings) Figure 12.5 26
Choose a large open working area. The tire should be positioned to have the tension chain (locking plate) on the lower side of the tire. Open the chain-shackle on the tensioning chain. Pull the tension chain through the rings, open locking plate and loosen the chain. Open the pin-shackle on the inside and outside (drive in the pin from below), disconnect the rings. Drive out the connecting rings (mechanical repair rings) pins and remove the forgings. Drive slowly forward or backward until the chain falls from the tire. 27

Congratulations on choosing QCC- Quality Chain Canada TPC (Tire Protection Chain). You have purchased a product manufactured by us using the most modern technology. However we are obliged by legal provisions to include the following warning against incorrect use. This warning must be complied with in all conditions of use and that we accept no liability for damage that is at least partly caused by the failure to comply with this warning. The chain must only be mounted by suitably trained and competent specialists. By using the tire protection chain you acknowledge that you and the corresponding specialists employed by you will take note of and comply with this warning. In case this warning is not complied with you will renounce any claim against the manufacturer and any dealer. The failure to comply with this warning could lead to product damage as well as personal injury with serious consequences. Never use tire protection chains for any other purpose than for mounting on tires. All parts of the chain, including spare parts are case-hardened to reduce wear and must therefore not be used for towing, lifting or misused in any other way. All the points in the mounting instruction must be strictly followed. The failure to do so can lead to malfunctions and damage to the vehicle as well as to accidents. Before using the vehicle for the first time after mounting the tire protection chain check that the chain is mounted correctly. In addition, the fit and state of wear of the chain should be regularly checked, at least every 200 hours of operation. When mounting or removing the chain or carrying out any other work on it please always remember its heavy dead weight. Incorrect handling can lead to serious injuries or damage caused by the chain falling off the tire. The tire protection chain must only be tensioned with the installation tool supplied or with a (come-along) tensioning chain hoist. Any other method of tensioning, such as with the shovel of a wheel-loader or a crane could damage the TPC and involve considerable danger to the mounting staff as it would submit the tension chain to excess strain, which may cause it to break. 29
Before mounting the tire protection chain please check that the tires are at the correct pressure and adjust if necessary. The tire pressure must not be reduced before the mounting and then increased again as this could overstrain and damage the tire tread. The resulting strain may break individual connecting rings or forgings at a later date. After mounting please check that no part of the tire protection chain contacts the vehicle. This should be carried out with the bucket or dump box lowered and the machine with its wheels turned hard over. (Loader) Correct tensioning of the tire protection chain means that it must fit to the tire in such a way that the individual forgings in the lateral chain can be moved easily. Broken forgings or rings must be replaced immediately by spare parts. In cases where spare parts are not immediately fitted there is the risk that other neighboring forgings or connection rings may break. Please take care that the wheels do not spin as this could lead to serious damage both to the TPC chain and to the tire. This leads to considerably increased wear and voids any guarantee of the chain. Do not use the tire protection chain on one wheel only-always mount in pairs. Tire protection chains may only be reconstructed to fit other tire sizes or shortened by appropriately trained specialists in a business authorized to carry out such work. We recommend to have the repaired chain inspected and approved by an expert. if in any doubt, please contact QCC Quality Chain Canada before using the repaired chain again. Please check the tension chain at regular intervals. As soon as one link has worn down by more than 1/3 of its cross-section, the entire tension chain must be replaced. QCC-Quality Chain Canada spare parts are recommended for repairs. Call Quality Chain Canada to verify if any other manufacturer s spare parts may be used. The tire protection chain has reached the end of its operating life when several forgings or rings break as a result of wear or the forged link has reached its minimum thickness. (see wear grooves on forged link) For reasons of economy we recommend that a maximum of 5% of rings and forgings of the chain be replaced. If more than 5% of the components (rings and 30
forgings) have been replaced by spare parts we recommend either a general overhaul of the tire protection chain or its replacement, depending on its general condition. We guarantee the use of specially tested steel according to expert analysis, superior manufacturing, correct surface hardness and proper fit of the tire protection chain. This warranty is valid for 2000 operating hours or 6 months and covers replacement of all faulty parts free of charge(except wear, thermal or other external influences). A sufficient number of spare parts is supplied with QCC tire protection chains free of charge. Additional spare parts will have to be charged.
