Retract All Jacks
Retract All Jacks is the function that pulls all four jacks fully in with a single command. It is the most critical step before setting off: a single jack left extended will strike the ground, a speed bump or a kerb along the way and destroy both the jack and its chassis mount. On the KTS200 it is provided as a separate safety function.
The function drives the jacks up to their topmost positions and stops them there. Single-button operation exists to eliminate the chance of forgetting a jack when breaking camp.
- Always verify visually after the command. Walk around the outside of the vehicle and check that all four jacks are fully retracted.
- A jack jammed under load may not retract; in that case lower the other jacks slightly to share the load first, then try again.
- In winter an iced-up or mud-packed jack retracts slowly; if the current protection trips during the retract command, do not force it — clean it and repeat.
Your departure checklist should run in this order: retract the jacks, verify all four visually, remove the wheel chocks, disconnect the shore power and water connections. Removing the chocks before the jacks can let the vehicle slide while it is still on the jacks; that is why the order matters.
