25WARNING:Like any mechanical device, a bicycle and itscomponents are subject to wear and stress.Different materials and mechanisms wear orfatigue from stress at different rates and havedifferent life cycles. If a component's life cycleis exceeded, the component can suddenly andcatastrophically fail, causing seriou7s injuryor death to the rider. Scratches, cracks, frayingand discoloration are signs of stress-causedfatigue and indicate that a part is at the end ofits useful life and needs to be replaced. Whilethe materials and workmanship of your bicycleor of individual components may be coveredby a warranty for a specified period of timebythe manufacturer, this is no guarantee that theproduct will last the term of the warranty.Product life is often related to the kind of ridingyou do and to the treatment to which yousubmit the bicycle cannot be broken or willlast forever. It only means that the bicycle iscovered subject to the terms of the warranty.Check the frame, particularly in the area aroundall tube joints; the handlebars; the stem; and theseat post for any deep scratches, cracks ordiscoloration. These are signs of stress-causedfatigue and indicate that a part is at the end ofits useful life and needs to be replaced.Break-in PeriodYour bike will last longer and work better if youbreak it in before riding it hard. Control cablesand wheel spokes may stretch or “seat” whena new bike is first used and may requirereadjustment by your dealer. Your MechanicalSafety Check will help you identify some thingsthat need readjustment. But even if everythingseems fine to you, it is best to take your bikeback to the dealer for a checkup. Dealerstypically suggest you bring the bike in for a30-day checkup. Another way to judge whenit is time for the first checkup is to bring thebike in after three to five hours of hard off-roaduse, or about 10-15 hours of on-road or morecasual off-road use. But if you think somethingis wrong with the bike, take it to your dealerbefore riding it again.After Every Long Hard RideIf the bike has been exposed to water or grit,or at least every 100 miles, clean it by wipingit clean and lightly oil the chain with a dry Teflonlubrication or a synthetic based chain lube.Then, very importantly, wipe off excess oil.Long lasting lubrication is a function of climate.(Hot or cold, wet or dry.) For general cyclelubrication, Dahon suggests using lightweightmineral based oil that is commonly availablein most bike shops or hardware stores. If youhave any questions, please talk to your dealeras an incorrect lubricant can damage thepainted surfaces.After Every Long Hard Ride orAfter 10 to 20 Hours of RidingSqueeze the front brake and rock the bikeforward and back. If you feel a clunk witheach forward or backward movement of thebike, you probably have a loose headset.Have your dealer check it.Lift the front wheel off the ground and swingit from side to side. If you feel any binding orroughness in the steering, you may have atight headset. Have your dealer check it.Grab one pedal and rock it toward and awayfrom the centerline of the bike; then do the samewith the other pedal. Anything feel I loose? If so,have your dealer check it.Take a look at the brake pads. Starting to lookworn or not hitting the wheel rim squarely?Time to have the dealer adjust or replace them.Carefully check the control cables and cablehousings. Any rust? Kinks? Fraying? If so, haveyour dealer replace them.Squeeze each adjoining pair of spokes on eitherside of each wheel between your thumb and indexfinger. Do they all feel about the same? If any feelloose, have your dealer check the wheel.Check to make sure that all parts and accessoriesare still secure, and tighten any that are not.
