Lower the stand onto the three trivets. If the oor is something other than concrete (e.g. wood, tiled,
etc.), you may wish to use pads under the trivets to provide protection for the oor. Lower the stand
by stepping down on the foot pedal to take the weight of the stand and rock your foot downward
using the ball of your foot to release the spring-loaded latch.
MAINTAIN SUFFICIENT PRESSURE ON THE FOOT PEDAL TO PREVENT THE STAND FROM
SUDDENLY DROPPING ONTO THE FLOOR WHEN THE LATCH IS RELEASED.
CRUSHING HAZARD! Stands are very heavy! Prior to lowering the stand, ensure area
below Tribrach is clear of all obstacles.
TRIPPING HAZARD! Due to the size of the footprint necessary for stand stability, the legs
of the stand can create a tripping hazard.
Stand Operation
With the intermediate tube fully retracted, attach the instrument / measuring equipment to the stand.
Raise the collar locking handle until the intermediate tube can be raised easily by rotating the
control handles.
To raise the intermediate tube, rotate the control handle counter-clockwise (when looking
at the hub).
!
TIPPING HAZARD! Move the stand over smooth, level surfaces only, with the intermediate
tube in its lowest position and no instrumentation / equipment attached. Move the stand by
manually pushing or pulling (no faster than a walking pace). Do not tow or push the stand
with a powered vehicle.
!
ROTATING HAZARD! The stands are equipped with an air-check mechanism to
prevent rapid descent of the intermediate tube. However, until sucient air pressure
has built up to slow the descent of the intermediate tube, considerable force can be
exerted by the free spinning control handle. Therefore, always lower the intermediate tube
by applying a resistive force to the control handle.
