2. Follow the general assembly instructions provided via GO V24 in the desired language (DE, EN, FR, ES, PT).
3. Determine the desired height of the bracket based on the distance A from the floor to the lower frame tube of the wheelchair.
4. Select the appropriate clamping position and torque for the screws based on the determined height.
5. Securely attach the clamp inside and outside the frame tubes using the provided screws and washer.
6. Install the drive wheel and control unit according to the assembly instructions.
7. Attach the cross bar with locking and push bar to complete the assembly.
8. If required, use the optional counter support for the bracket of the control unit.
9. Ensure that the via GO is properly aligned and functioning before use.

Please refer to the complete user manual for detailed instructions, including specific torque values and additional safety precautions.

Important safety information

Work on the via GO, its individual components and the bracket on the wheelchair may only be carried out by persons who have been authorized by Alber to carry out this work.

Attention! The via GO has no braking function. Therefore, the wheelchair must be equipped with brakes if the operators are physically unable to bring the wheelchair to a stop in all driving situations. Ideally, these brakes are two drum brakes.

General information about the bracket for the via GO
The bracket for the via GO is designed for combination with standard and lightweight wheelchairs with a frame tube diameter of 25 mm / 1 inch. Depending on the seat width, there are different pre-mounted brackets.
For wheelchairs to which this standard bracket cannot be attached, there are optional extensions depending on the wheelchair. For these cases, please observe the mounting instructions enclosed with these extensions.

Preparing the mounting of the bracket for via GO

Preparing the wheelchair and getting parts ready

• Align the wheelchair.
• Tighten the two knee lever brakes.
• Get the following parts ready:
  • Bracket for the drive unit
  • Meter stick/tape measure
  • Allen wrench SW5
  • Torque wrench

Determine the height of the bracket

• Measure the distance A from the floor to the lower frame tube [5] of the wheelchair.

Example:
The distance A from the floor to the lower edge of the lower frame tube [5] of the wheelchair is 232 mm. Therefore, screw the adapter [3] to the outer clamp [2] at position 4 and 5.

Mount and adjust the bracket for the via GO on the wheelchair

Attention! Do not damage the spokes of the wheelchair wheels or the lower frame tube of the wheelchair when mounting the screws of the bracket of the drive unit!

Mount the bracket on the wheelchair

• Mount each of the two screws on the holders [3] with a torque wrench as specified in chapter 3.2.
• Use an Allen key to unscrew the screws from the inner clamps [1] and the outer clamps [2].
• Fold the inner clamp [1] on one side of the bracket of the drive unit vertically upwards.
• Lift this side of the bracket of the drive unit until you can fold the inner clamp [1] down. Now the two clamps [1 and 2] must enclose the lower frame tube [5] (see illustration).
• Tighten the screw of the inner and outer clamps [1 and 2] only slightly with an Allen key.
• Mount the other side of the bracket on the other lower frame tube of the wheelchair as described.

Set the point of contact of via GO

• Attach the via GO to the bracket of the drive unit as described in the instructions for use.
• The contact point P of the via GO drive wheel should be between the contact points of the drive wheels of the wheelchair, tolerance depending on the wheelchair approx. +/- 50 mm. The distance B of the inner and outer clamps [1 and 2] to the rear frame tubes [4] or the axle mounts should be the same on both sides of the wheelchair. If the contact point P of the drive wheel of the via GO meets the above require-ments: Tighten the screws of the inner and outer clamps [1 and 2] with a torque wrench and a tightening torque of 8 Nm.

If the contact point P of the via GO drive wheel is outside the tolerance range or / and the distance B is unequal:

• Use an Allen key to loosen the screws of the inner and outer clamps [1 and 2].
• Move the inner and outer clamps [1 and 2] on the lower frame tubes [5] of the wheelchair until the contact point P meets the requirements.
• Tighten the screws of the inner and outer clamps [1 and 2] using a torque wrench and a tightening torque of 8 Nm.

Adjust the screws of the push bars
The contact point of the via GO drive wheel must be located centrally between the contact points of the drive wheels [8] of the wheelchair.
If the contact point of the via GO drive wheel is centered between the contact points of the drive wheels [8] of the wheelchair:

• Tighten the screws of the push bars [7] with a torque wrench and a tightening torque of 8 Nm.

If the contact point of the via GO drive wheel [8] is not centered between the contact points of the wheelchair wheels:

• Loosen the screws of the push bars [7] with an Allen key.
• Move the screws of the push bars [7] until the contact point is centered between the contact points of the drive wheels [8] of the wheelchair.
• Tighten the screws of the push bars [7] with a torque wrench and a tightening torque of 8 Nm.

Check the height of the bracket and the secure fit of the drive unit on the bracket

• Measure the distance H between the upper edge of the crossbar [6] and the floor. The distance H should be 175 mm in the center of the bracket, tolerance: +/- 15 mm.
• If the distance H is within the tolerance range: Tighten the screws of the holders [3] with a torque wrench and a tightening torque of 8 Nm.
• If the distance H is smaller than 160 mm or larger than 190 mm, correct the distance (see chapter 3.2): Loosen the screws of the holders [3], bring the hol-ders into one of the described positions and tighten the screws of the holders [3] again.
• Attach the via GO to the bracket as described in the via GO operating instructions.
• Check that the via GO is correctly positioned on the bracket of the drive unit and that the via GO is securely attached to the bracket (see the via GO user manual).

Attention! Check the function of the brakes after mounting the bracket for via GO on the wheelchair.

General information about the bracket for the control unit
The bracket for the via GO control unit is usually mounted on the existing brake lever of the wheelchair. For mounting separately from the brake lever of the wheelchair or on a push bar, there is the optional accessory „Counter support control unit via GO“. Mounting the bracket of the control unit on the left side of the wheelchair is not intended: The control unit can also be operated by left-handers, for example, if it is mounted on the right side of the wheelchair.

Mount the bracket for the control unit

On a wheelchair with drum brakes

• Unscrew the screws from the upper bracket [12] of the brake lever.
• Replace the upper bracket of the brake lever with the bracket of the control unit [12]. The bulge of the bracket of the control unit [12] should point forward as seen in the direction of travel.
• Tighten the screws [10] of the bracket of the control unit [12] with a tightening torque according to the specifications of the wheelchair manufacturer.

Mount the bracket for the control unit – on a wheelchair without drum brakes

• Place the upper bracket (the bracket of the control unit [12]), the washers [11] and the screws [10] on the optional counter bracket [14]. The bulge of the bracket of the control unit [12] should point forward as seen in the direction of travel.
• Tighten the screws [10] of the bracket of the control unit [12] with a tightening torque according to the specifications of the wheelchair manufacturer.
