Fusion 100 and 200
Adjusting the safety collar requires
the use of the hex key, which is
conveniently stored on the back left
of the pump, right above the power
switch. Loosening the hex screw on
the safety collar allows for the collar
to be slid freely along the guide rod
and then securely tightened at the
desired position. The position of the
safety collar should be set slightly
further from the syringe-block holder
than the top of syringe plunger when
fully depressed.
Caution
On the Fusion 200, during withdrawal, a syringe plunger can potentially be pulled out from the
syringe, which could cause the contents of the syringe to leak out. Users should be especially
aware of the length of the plunger and the point where the withdrawing pusher block will
exceed that length. There are no safety collars on the Fusion 200 to prevent too much
withdrawal.
Fusion 400
The Fusion 400 uses a safety bar
instead of a collar to limit the
distance the pusher block may
travel. By loosening the safety bar
clamp knob on top of the pusher
block, the safety bar can be slid left
or right. The safety bar should be set
such that the length of the bar
exposed on the right side of the
pusher block is longer than the
distance from the top of a fully
depressed syringe plunger to the
edge of the syringe-holder block.
Once the safety bar has been set to
the proper length, tightening the
