Quattrocycle BVUser Manual Quattrocycle 8Chapter 3MaintenanceThe Quattrocycle should be checked by a bike mechanic after transportation andafter each 500 to 1000 km of riding. The check points are described in the followingchapters.3.1 Tensioning the chainsThe chains will gradually elongate during riding. Therefore they need to be checkedand tensioned time by time. In particular new chains will initially elongateconsiderably. Therefore, tensioning the chains for the first time will be needed quitesoon, typically after something like 20 km.Tensioning the chains is done as follows:1. Tensioning of the two rear chains: Remove the gear shifter from the rear gear hub using an allen key. Loosen the nuts of the gear hub Move the gear hub to the front until the chain is tight and tighten the nuts. Put the gear shifter back on the gear hub.2. Tensioning the chains between the two gear hubs. This is done by moving thefront gear hub to the front, in the same we as done for the rear hub in step 1.3. Tensioning of the four chains between the gear hubs and the crank stets: Loosen the M4 bolt that connects the chain cover to the frame a couple ofturns so that the chain cover can move through the slotted hole in the frame. Loosen the M8 bolts that connects the crank shaft housing to the frame acouple of turns. Move the crank shaft housing to the front till the chain is tight. Tighten the M8 bolts. Tighten the M4 bolt at the rear of the chain cover.Starting 2009, Quattrocycles have automatic chain tensioners on all chains exceptthe chains between the rear crank set and the rear gear hubs. The above procedureis then only needed for these chains and for the other chains once the automatictensioners are at the end of their range.3.2 Checking of the brakesThe Quattrocycle has 4 mechanically operated drum brakes. The brakes need to bechecked frequently, also the park brakes on the brake levers. After some time thebrake cables will elongate somewhat and the brake shoes will wear, then the brakecables need to be readjusted using the adjustment screws at the wheels to keep theright braking performance. Brake cables that show wear and worn out brake shoesneed to be replaced in time to keep a good braking performance.3.3 Checking of the steering |
