Remove the old foldable push handle.
Pull down the backrest cover F on the telescopic tube, until its
hole B is uncovered.
IMPORTANT!
Make sure that the threaded insert E (part no. 1580450) supplied
with the new push handle is used for assembly.
Place the threaded insert E in the telescopic tube.
Punch a hole through the backrest cover with a distance of
10 mm from the upper egde, using hole punch pliers (see graphic
below).
Slide the new foldable push handle A onto the telescopic tube.
Pull up the backrest cover, until it covers completely the rear hole
in the pushhandle.
Fix the foldable push handle with screw C and washer G.
Check screws D on both sides of the push handle and re-tighten
if necessary.
Carry out the same steps for the other push handle.
IMPORTANT!
Make sure that the folding force is approximately 5 N (0.5 kg).
IMPORTANT!
Fixing screw C may only be used once. Alternatively the screw can
be cleaned (remove old thread locking adhesive) and reinstalled
with new low-strength thread locking adhesive.
