BICYCLE MAINTENANCE<br />
First servicing<br />
During the bicycle’s breaking-in period, the bicycle parts settle into place, which is<br />
why we recommend the first servicing to be carried out after you have ridden c. 200<br />
km. The inspection should include brake and gear adjustments, checking the<br />
bearings, tightening the screws and nuts, balancing the front and back wheel,<br />
tightening the spokes and, on bicycles with hub gears, an adjustment of the tension<br />
of the chain. It is especially important to check the spokes, since the spokes and the<br />
male couplings of the spokes only settle in place after being broken in. It is<br />
recommended to let a professional tighten the spokes.<br />
Regular maintenance<br />
For the safety and long-life of your bicycle, we recommend maintenance intervals of<br />
about six months (for example, in the spring and autumn), at which time the brakes,<br />
gears, bearings, pedals, wheels, chains, lock and cables should be checked, cleaned<br />
and lubricated. An easy way to take care of regular maintenance is to take your bike<br />
to a <strong>Helkama</strong> dealer.<br />
Cleaning<br />
DO NOT USE A HIGH PRESSURE SPRAY WASHER!<br />
Brakes<br />
Coaster brakes built into the hub do not require any special care or adjustments.<br />
They should be checked at the same time as the hub. If the coaster brakes require<br />
repairs, consult a <strong>Helkama</strong> dealer.<br />
The distance between the rim brake pads and the rim of the wheel is about 2-3 mm.<br />
The distance can be adjusted on the adjuster sleeve by the cable casing. The brake<br />
pads must be set in the center of the rim (Fig. 7). Worn out brake pads must be<br />
replaced.<br />
Make sure not to get lubricant or wax on the rim or brake pads.<br />
