18) CHECKING THE POSITION OF THE OVER-RUN
DEVICE CAM AND PLATES
Before nal testing of the stairlift, check that the limit
stop (Fig. 60/a-61/a) is correctly positioned.
This position is correct if the dimensions are as shown
in the drawings in Fig. 60 and 61.
19) STRETCHING THE CHAIN
Stretch the chain (Fig. 62/b) by undoing the nuts (Fig.
62/e) and screwing down the hexagon (Fig. 62/a).
Take care not to apply excessive tension, as this will
mean too much strain on the drive shafts (Fig. 62/c and
Fig. 62/d). Tighten the nuts (Fig. 62/e) rmly when done.
20) FINAL TESTING
Supply power to the system and perform the fol-
lowing functional checks:
- Load test:
- Load the stairlift with 1.1 times the rated load stated
on the nameplate.
- Send the stairlift up and down several times, checking
its stability on the rail.
- Final testing for stairlifts with sections of rail ha-
ving gradient of less than 20°:
- Move the stairlift to the area with gradient of more than
25° and check that the cam drive roller is 0.5÷1.5 mm
from the cam (see Fig. 64).
- If the roller has to be moved towards or away from the
cam, remove the bracket (Fig. 67/a) and turn the clutch
wheel hub (Fig. 67/b) using the spanner provided (Fig.
67/c). After adjustment (30 daN/m) t the bracket (Fig.
65/a) and x the two screws (Fig. 67/d) with 243 loctite.
- Then move the stairlift to the area with gradient of
less than 20°, and place a weight of 250 kg on it with its
centre of gravity 150 mm from the edge (see Fig. 63).
- Check that the stairlift does not tilt by more than 2°.
- Preliminary checks
Perform the checks described in point 6.1 on page 8
of the Use and Maintenance Manual.
- Safety gear test
Test the safety gear as described in Section 10.1, point
“d”. (This test must be carried out with no load on the
stairlift).
- Checking the interlocking of the platform with
independent or retractable arms (manual platform)
- Check that as long as the down side bar is in the rest
position the platform remains locked, whether in the
working or the rest position.
