TOWING

Towing the Niftylift in case of an emergency. If necessary, chock the wheels before carrying out any of
the following actions.
5.5.1 GEARBOX DISENGAGEMENT
In order to safely tow the HR21 Hybrid, the drive mechanism and parking brakes will need to be
bypassed. The drive gearboxes located on the front and rear wheel hubs must be disengaged as
follows;
1) Remove both retaining bolts that secure the cover disc to the centre of the wheel hub.
2) Partially screw one of the retaining bolts into the end of the central disengage pin and pull the pin
out fully, ensuring the recess on the pin is visible.
3) Place the cover disc over the pin, ensuring the retaining disc is engaged in the pin recess and
secure in place using the remaining retaining bolt.
4) To re-engage the gearbox complete the above instructions in reverse order, ensure gearbox
drive is free to engage before pushing the pin 'home'. If necessary, jack up each wheel & rotate
slightly to allow re-engagement of pin.
Damage caused by failure to comply with these procedures will not be covered by the
manufacturer's warranty.

provided to allow correct front wheel alignment prior to towing. To operate, move the lever up for
steering left, or down for steering right whilst operating the hand pump.
