HOW TO CLOSE THE TRIPOD 7
Open the lever "B" and then close the tripod by pushing down on it as shown in the
image.
Lock all the clips "A".
To avoid the risk of injury, please keep fingers away from the mechanism.
Before mounting equipment onto the tripod, check the leg load capacity. If the leg
requires adjustment, please refer to the "Maintenance" section of this manual.

CHECK LEG LOAD CAPACITY
Periodically check the effectiveness of the leg brake force in order to verify that is
operating correctly and adjust if necessary.
1. Remove the mid-level or ground spreader from the tripod in order to facilitate follow-
ing steps
2. Extend the middle and lower sections to 23 cm (9in) each (approximately half their
maximum length).
3. Place a rubber mat or similar "AC" on a set of scales to prevent damage and skid-
ding. Stand one leg on the scales and apply a vertical downward force.
WARNING! Use a non-slip mat to ensure the tripod foot does not slip from the scales
when applying downward pressure.
WARNING! Finger entrapment hazard. Make sure you keep fingers clear, so they do
not become trapped in the legs.
4. The leg should remain extended while applying an average downward force of 25-
35 kg (55 - 77 lb)
5. If the leg starts to collapse before a 25 kg (55 lb) force is reached, then the corre-
sponding leg section requires adjustment. Check to see which section and which
locking collar has collapsed and refer to "Adjusting brake force section".

ADJUSTING BRAKE FORCE
Brake force must be adjusted with the locking collar levers closed, as shown in this
image.
To adjust the brake force on the upper section (fig. 9), use the supplied Allen key "M"
to turn the screw "N" clockwise in MAX 1/8 of a turn steps: after each adjustment step,
check the Load Capacity again (referring to the CHECK LEG LOAD CAPACITY section
above).
To adjust the brake force on the lower section (fig. 10) use the supplied Allen key "M"
to turn the screw "P" clockwise in MAX 1/8 of a turn steps: after each adjustment step,
check the Load Capacity again (referring to the CHECK LEG LOAD CAPACITY section
above).
Small rotations of the Allen key result in large load increases (1/8 of a turn= +5 kg (11lb)
fig. 9).
Do not adjust more than necessary, as this will lead to increased stress on the locking
mechanisms.
Excessive adjustment may compromise the fluidity of movement of the sections
