KDS120 Push-Pull pump
To facilitate loading , the pusher block can be released from the leadscrew by pressing the
bronze button (1) and can be manually moved along the guide rods to accommodate the
syringes.
First place the withdraw syringe in the withdraw syringe holder, using the spring loaded retaining
clamp to retain the syringe barrel in the V of the syringe holder.
Make sure the barrel flange is held firmly by the withdraw clamp and that the adjusting screws on
the withdraw clamp are firmly tightened.
While keeping the button (1) pressed firmly "in" slide the block along the guide rods so that the
syringe plunger flange can be retained by the clamp on the pusher block.
Tighten the locking screws on the adjusted syringe clamp .
Loosen the locking screw on the Adjustable syringe rest and position the rest so that the plunger
of the loaded syringe is pressed firmly against the pusher block and the syringe barrel flange is
pressed up to the syringe rest.
The barrel of the loaded , infusion syringe should be clamped in the V of the syringe holder with
the spring loaded clamp.
Tighten the screw on the syringe rest to lock the rest in place on the guide rod.

MANUAL STALL SETTING AND MICROLITER SYRINGES
A movable collar, located on the rear guide rod, can be set to restrict travel of the pusher block.
The block moves until stalling against the collar. Stalling does no permanent damage but may
result in increased wear on the drive mechanism and should not be used routinely but only as a
"fail safe" device.
Microliter syringes with fine wire plungers can be damaged if the plunger is forced into the end of
the syringe barrel; the collar can be adjusted to prevent this occurrence.
