Küschall® Champion
Replacing the handle
An adhesive (for example, hair spray) is used in these instructions. When applied to the handle, this substance works
as a lubricant and as an adhesive once dry.
CAUTION!
Risk of accidents
The handle can come loose from the tube if not correctly bonded.
– Make sure that the handle resists a pull-off force of 750 Nm after drying.
Adhesive (e.g. hair spray)
■■□
1. Remove the old handle.
2. Remove any residue (residual adhesive, grease, dust)
from the push handle tube.
3. Apply a thin layer of hair spray all over the surface of the
push handle tube onto which the handle is to be slid.
4. Apply a thin layer of hair spray to the inside of the
handle.
5. Slide the new handle onto the push handle tube.
6. Move the handle into the correct position (grooves
facing upwards).
If a long handle has been fitted and this is to be replaced with a short one, the push handle tube must be
shortened by 35 mm. The push handle tube must be replaced when switching from a short to a long handle.
Replacing foldable push handles
Hole punch pliers (6 mm) / Allen key (3 mm, 4 mm)
■□□
1. Remove the old foldable push handle.
2. Pull down the backrest cover F on the telescopic tube,
until hole
B
is uncovered.
IMPORTANT!
– Make sure that the threaded insert
E
supplied with
the new push handle is used for assembly.
3. Place the threaded insert E in the telescopic tube.
4. Punch a hole through the backrest cover with a distance
of 10 mm from the upper edge, using hole punch pliers
(see lower graphic to the right).
5. Slide the new foldable push handle A onto the
telescopic tube.
6. Pull up the backrest cover, until it completely covers the
rear hole in the push handle.
7. Fix the foldable push handle with screw C and washer
G .
8. Check screws D on both sides of the push handle and
re-tighten if necessary.
9. 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.
The retrofit of foldable push handles requires new
tubing.
C =7 Nm (low-strength)
