User guidelines
Before use

Trailer
If a trailer is attached, remember that braking distance will increase. Do not attach trailers on steep slopes. No passengers are allowed in the trailer.
Maintenance
Regular maintenance is required to ensure the longevity and safety of the go-kart.


Maintenance scheme
- Daily: Check tires for wear and pressure.
- Monthly: Clean and check all nuts and bolts; check frame for cracks; lubricate moving parts; check chain tension.
- Half-Yearly: Check functioning of bearings, chain, hub, sprockets, and axles.
- Yearly: Clean plastic parts and check for damage.
Chain tensioning
The go-kart has two chains. If a chain is too tight, pedaling becomes difficult; if too loose, it may come off. Always tension the rear chain first.
Crank adjustment
After the first few days of intensive use or two weeks of normal use, tighten the crank mounting bolts to a maximum of 30 Nm to prevent play and damage.
Warranty
The frame and other parts have a 2-year warranty from the date of purchase. Wear-and-tear parts like chains and tires are excluded. Warranty claims require the original purchase receipt and the serial number found on the frame.
