Maintenance
Checking brake force
Periodically check the effectiveness of the leg brake force and adjust
if necessary.
1.
Extend the middle and lower sections to 20 cm each.
2.
Place a rubber mat or similar on a set of scales to prevent
damage and skidding. Stand one leg on a set of scales and apply
a vertical downward force.
WARNING! Use a non-slip mat to ensure the
!
foot does not slip from the scales when applying
downward pressure.
WARNING! Finger entrapment. Take care not to trap
fingers.

3.
With an average downward force of
20 - 30 kg (44 - 66 lb) flowtech 75 or
30 - 40 kg (66 - 88 lb) flowtech 100
applied, the leg should remain
extended.
4.
If the leg starts to collapse before a
20 kg (44 lb) flowtech 75 or
30 kg (66 lb) flowtech 100
force is achieved then
adjustment is required.

Adjusting brake force
1.
Lift the quick release lever to clear the adjustment screw. Using a
2.5mm or 3/32" hex key, turn clockwise to increase the brake force.
2.
10 full turns = 2 kg (4.4 lb) of additional brake force.
CAUTION! Do not adjust more than required as this
!
will lead to increased wear and stress on the brake
components.
3.
When the adjustment is made, test the brake force
again on the scales, repeat if necessary.
4.
Repeat the procedure for the remaining two legs.
Should the adjustment range become
insufficient to achieve the correct brake force,
please contact your local service centre.
