b) Delete as necessary.
c) Delete as necessary.
d) Test battery charge condition using the
four volt drop principle.
e) Visually check for any leaks or corrosion.

Component Functioning
k) Record the stopping distance (must not
exceed 20mm).
l)
Check operation of carriage control
buttons.
m) Confirm the tested mark is present on the
overspeed governor assembly.
n) Carry out Installation overload testing.
Refer to index on page 3 for work method.
o) Confirm carriage and Retractable rail
alarms and warning LED operate.

q) Where 2 stairlifts are fitted on the same
staircase, ensure that there is a minimum
clearance of 500mm between adjacent
footrests when unfolded.
r)
Delete as necessary
s) Delete as necessary
t)
Confirm that hazard warning labels where
supplied are fitted to carriage and
retractable rail.
u) Record footrest heights.
v) Record seat heights
5—Confirmation
The stairlift user must be fully instructed on the
use of the stairlift, including the emergency
handwinding procedures. All operating
instructions should be handed over to the user
on completion.
Section 6—Declaration
