Installation Procedure

General Installation Warning

Ensure supplied items are suitable for the wheelchair before starting installation.

Clamping Ring Positioning

Temporarily remove seat/parts to identify and position clamping rings on the frame.

Clamping Ring Installation

Install clamping rings on the frame, orienting screws correctly for upper/lower tubes.

Clamping Ring Compatibility

Check compatibility and positioning of clamping rings relative to other components.

Converging Frame Warning

Caution for converging frames; use a level for accurate perpendicular alignment.

Horizontal Alignment Method

Secure one ring, insert crossbeam, fix with pin, align second ring for free movement.

Vertical Alignment Method

Details vertical alignment for oval, converging, and parallel frames.

Post-Alignment Warnings

Verify user needs, ensure crossbeam removal, and check centering/parallelism.

Securing Clamping Rings

Lightly tighten fixing clamps' screws to maintain their position.

Final Torque for Clamping Rings

Tighten clamping ring screws to 10Nm with copper grease, ensuring alignment.

Centering the Crossbeam

Ensure the crossbeam is centered and parallel to the ground.

Centering the Crossbeam Adjustment

Adjust crossbeam position centrally with tolerance ± 0.5 mm and tighten screws.

Reassembling Components

Reassemble parts removed earlier (brakes, seat supports) to their correct positions.

Connector Adjustment

Connector Insertion into Crossbeam

Insert the Connector into the Crossbeam, ensuring free rotation for adjustment.

Front Hook Provisional Tightening

Provisionally tighten Front Hook screws to eliminate all backlashes.

Initial Pin Seating

Place Twist on ground, bring wheelchair closer until upper pin rests on Front Hook seat.

Securing Upper Pin Position

Lightly tighten fixing clamps' screws to maintain the upper pin's position.

Linking Lever Operation and Safety Check

Lift Linking Lever; check for green sign indicating safe and correct linking.

Wheel Forward Movement

Push wheelchair wheels forward to establish complete linking and lift front castors.

Footrest Clearance Check

Check distance between Twist and footrest to ensure no contact during rotation.

Connector Extension Procedure

If necessary, extend the Connector by loosening screws and adjusting to user's need.

Connector Length Trimming

If the Connector is too long, cut the excess part of the smaller oval to size.

Final Connector Screw Torque

Apply copper grease and tighten the two fixing screws to 10 Nm.

Steering Angle Setup

Adjust steering set-up by checking angle relative to ground; recommends 2-6 degrees.

Scenario 1: 0° Inclination

0° inclination: neutral steering, suitable for low speeds, lifts front castors.

Scenario 2: Up to 6° Inclination

Up to 6° inclination: more directionality, harder steering, lifts front castors minimally.

Note on 5-6° Inclination

Mounting at 5° or 6° is suitable for riding with the handlebar installed.

Scenario 3: Below 0° Inclination

Inclination below 0° causes instability and is incompatible with correct usage.

Final Front Hook Tightening

Once correct position is found, definitively tighten the 4 fixing screws to 10 Nm.

Lower Pin Disengagement

Raise Unlinking Lever to disengage lower pin; Twist rests on stand, engaged to upper pin.

Twist Disengagement

Press the red Safety Button to completely disengage the Twist from the Linking System.

Re-adjusting Connector Inclination

Unscrew clamps, bring wheelchair closer, adjust connector inclination until upper pin rests on seat.

Securing Adjusted Connector

Tighten fixing clamps lightly to secure the connector's adjusted position.

User Seated Alignment Verification

User sits on wheelchair; check alignment and engage Front Hook by maneuvering.

Finalization

Final Crossbeam Torque

Permanently tighten crossbeam securing screws to 25 Nm with copper grease.

Final Installation Checks

Check all screws are tight; test linking/unlinking operations with user or similar weight.

Permanent Crossbeam Fix

Permanently fix crossbeam position using Spring Type Straight Pins.

Drilling for Permanent Fix

Adjust strap, drill a 5mm hole into the crossbeam strap.

Inserting Permanent Pins

Insert Spring Type Straight Pins into drilled holes and fix with a hammer.
