Like any piece of equipment, the better you look after your R1 or R1-S trolley the better it will perform and the longer it will last.
When we were designing it, a major part of the brief was to make it as easy as possible to maintain - and we did just that.
The gears and folding mechanism of the trolley are all enclosed and so there are no sleeves or sliders to trap dirt and mud, but you still need to keep the trolley clean: If you have a compressed air line at the course, use it to clean down the trolley - particularly the wheels - after each time you play. In addition, wipe down the frame and the mouldings with a damp cloth and then dry them afterwards.
Also use the air line to make sure no dirt or grit has got into the brake mechanism - if anything is allowed to build up inside the brake and stop it working there is a danger than you might break it by forcing it.
You should wash the wheels regularly: remove them from the trolley using the quick release mechanisms and rinse under a tap. Be sure to re-fit the front wheel securely, with the locking clips on either side of the housing both fully engaged.
Finally, if you want to lubricate the gear mechanism you should use PTFE spray rather than a water displacement spray such as standard WD40: open the latch at the bottom of the main support and spray down into the gear mechanism, but be aware that some of the PTFE spray may leak out and so it’s probably best to do this outside and not on your best carpet!
