VI. Operation and maintenance
The height adjustment is done as follows:
a)
while holding the telescope tubes press the
spring-loaded buttons simultaneously,
b)
slide the telescopes down or up to adjust the
height until the buttons click,
c)
next the hurdle toppling force should be
adjusted accordingly, so press and hold the
knob in the hurdle foot,
d)
then slide the counterweight to the
corresponding height according to the label,
then release the knob, do the same with the
other hurdle foot.
During idle periods the hurdles must be stored in a roofed dry place. For optimal performance they should be stored
and transported on Polanik hurdle carts: HC-23 and HC-34.
After every athletics season the hurdles must be cleaned from sand (mud, dust and etc). Special attention is required
for the counterweight sliding mechanisms, which should be dismounted, cleaned and greased.
