Hi Matthew, as Ken says, there is very little to worry about in terms of maintaining your Model 30, here is a few tips.
When you have clocked a few initial miles, just go back over fixings and fastenings from when you built it, as things settle down on anything mechanical once it is first used.
Ongoing, To get the maximum life out of your battery Keep it charged, if you have ridden it charge it afterwards, don’t park it up for more than a couple of days with a partly discharged battery, but after a long ride (10 miles or so) it is a good idea (but not essential) to let the battery cool off for 30 minutes before charging, this helps to the battery to absorb a charge better.
Keep the brakes adjusted, this is simply a matter of turning the adjusters on the brake arms, set them as you would with a cycle, so that you can brake hard without the levers touching the handlebars, but with some free travel at the beginning of the pull so that they don’t bind.
Periodically Check the tyre pressures, I find 30psi front, and 32psi rear is about right for comfort and handling, and have a look around the tyres for any damage or objects embedded in the tyres.
Switch on the lights and indicators and walk around the scooter to make sure they are all working, squeeze the brakes and check th brake lights.
Maybe run a spanner over things like wheel spindle nuts, mirrors, and any other visible fastenings.
And that’s pretty much a service, it takes around 5 minutes every 2 – 3 months.
Enjoy : )
