2. Safety Information
Your safety and the safety of others are paramount. Adhere to all warnings and precautions outlined in this manual.
- Do not drive with the step extended. The Thule Double Step is equipped with a standard switch that can be connected to your vehicle's warning lamp to alert you if the step is still extended while the vehicle is in motion. Ensure this connection is properly made and functioning.
- Ensure the step is fully retracted before driving to prevent damage to the step or vehicle, and to avoid accidents.
- Do not exceed the maximum weight capacity of the step. Refer to the specifications section for details.
- Keep hands and feet clear of moving parts during operation.
- Regularly inspect the step for any signs of wear, damage, or loose fasteners. Do not use if damaged.
- Installation should be performed by a qualified technician if you are unsure of the process.
3. Setup and Installation
The Thule Double Step is designed for installation on motorhomes and caravans. Proper installation is crucial for safety and functionality.
3.1. Pre-Installation Checks
- Verify that the mounting surface on your vehicle is strong enough to support the step and its intended load.
- Ensure there is sufficient clearance for the step to extend and retract without obstruction.
- Confirm that your vehicle has a compatible 12V power supply for the step's motor.
3.2. Electrical Connection
- Connect the step's 12V motor to your vehicle's electrical system according to the wiring diagram provided in the separate installation guide (if applicable).
- Crucially, connect the integrated switch to your vehicle's warning lamp circuit. This feature is designed to prevent accidental driving with the step extended by providing a visual or audible alert inside the vehicle.
3.3. Mounting
- Securely mount the step to the vehicle chassis using appropriate fasteners. Ensure all bolts are tightened to the manufacturer's specifications.
- Test the step's extension and retraction several times after installation to confirm smooth operation and proper alignment.
4. Operating Instructions
The Thule Double Step operates via a simple 12V motor system.
- To extend the step: Locate the control switch inside your vehicle (typically near the entrance). Activate the switch to extend the step. The step will fully extend and lock into position.
- To retract the step: Activate the control switch again to retract the step. Ensure the area around the step is clear before retraction. The step will fully retract and stow securely.
- Always ensure the step is fully extended and stable before stepping on it.
- Always ensure the step is fully retracted before moving the vehicle. The warning lamp connection is a critical safety feature for this purpose.
5. Maintenance
Regular maintenance will ensure the longevity and reliable operation of your Thule Double Step.
- Cleaning: Clean the step regularly with mild soap and water. Avoid abrasive cleaners or solvents that could damage the anodized aluminum finish or anti-slip strips.
- Lubrication: Periodically lubricate the pivot points and moving mechanisms with a suitable silicone-based lubricant to ensure smooth operation. Do not over-lubricate.
- Inspection: Regularly check all fasteners for tightness. Inspect the step for any signs of corrosion, cracks, bends, or damage to the anti-slip strips. Check the electrical wiring for fraying or loose connections.
- Winterization: In cold climates, ensure the step is free of ice and snow before operation. Do not force the step if it is frozen.
