Track Tension Adjustment (Speed Adjustment)
If passengers usually weigh
between 45 and 90 kg (100 to
200 lbs), descent will be easier if
Track tension is decreased. To
do this, loosen the lock nuts and
loosen the Track Tension
Adjusting Bolts by one complete
revolution counter-clockwise. Be
sure to adjust each Track by the
same amount. Tighten the lock
nuts.
Test the unit on a stairway,
loaded with the desired weight.
If passengers usually weigh less
than 45 kg (100 lbs), descent will
be easier if track tension is
decreased further. Loosen the
lock nuts and loosen the Track
Tension Adjusting Bolts by 1 ½
revolutions counter-clockwise
from the factory setting. Tighten
the lock nuts.
Test the unit on a stairway,
loaded with the desired weight.
If passengers usually weigh more
than 120 kg (265 lbs), increasing
track tension can slow descent
speed. To do so, loosen the lock
nuts and tighten the Track
Tension Adjusting Bolts by one
complete revolution clockwise
from the factory setting. Tighten
the lock nuts.
Test the unit on a stairway,
loaded with the desired weight.
Note:
Track tension adjustment
has limited effect on descent
speed. For heavier
passengers use the brake for
additional speed control.
Lightly squeeze the Brake
Release Bar until the desired
descent speed is attained.
