To simplify syringe loading, the pusher block can be disengaged from the leadscrew by turn-
ing the knob(1) and manually moved along the guide rods. Alternately, the Fast forward,
Fast reverse feature can be used (press Run and respective Arrow key simultaneously).
Knob (1) is rotated to release the drive nut from the leadscrew. When the white line on the
knob is facing toward the syringe barrel the drive nut is engaged and when the white line
faces the keypad the nut is disengaged.
Raise and rotate the spring loaded retaining arm (2) and place the syringe barrel in the "V"
of the syringe holder. With the syringe in place release the retaining arm so that it clamps
down on the barrel and holds it securely in place.
Release the pusher block mechanism and slide the block along the guide rods until the block
presses firmly against the syringe plunger. Rotate the knob (1) to re-engage the drive nut.
KDS210 AND KDS230 WITHDRAWAL OPERATION
For withdrawal, or refill operation, the syringe plunger and barrel flange must be secured by
additional brackets.
Loosen screws (3) on the syringe holder and, after loading the syringe, press the retaining
bracket against the barrel flange to secure the flange between the bracket and syringe
holder. Tighten screws (3).
To restrain the plunger, rotate knob (4) to release the retaining bracket and position the
syringe plunger between the pusher block and retaining bracket. Turn knob (4) clockwise to
tighten the retaining bracket and then re-engage the drive nut knob (1).
The mechanism is designed to accommodate a wide range of syringe sizes however, there
are some syringes which require additional attention. (See page 12)
