d) The models
let the piston go; it will fall by its own weight. If this is not the case, please apply the
dosing piston manually.
SAFETY, SAFETY S
The models
liquid push the piston down to the zero-position using the finger guard.
The stopper cap of the discharge tube may never come into the dosing jet, in order
!
to avoid dangerous squirting.
e) Avoid uneven and strong piston movements or jerking of the stopper ring.
f) Replace stopper cap after dispensing by holding the discharge tube tight with other
hand.
Warning:
!
If the stopper cap is not removed when dispensing, there
may be an overpressure in the channel system and un-
controlled dispensing may be the result.
To fill the dispenser the first time lift and lower piston a
short distance several times until no air bubbles are seen
in the cylinder.
HF:
Lift and dose the piston several times to fill the channel
system.
2. Volume setting
Loosen the nut of the volume setting system, set the
desired volume. The upper edge of the fine adjustment
screw shows the volume set. Fix the screw.
For calibrating purposes turn the screw of the fine ad-
justment. Turn downwards to increase the volume, turn
upwards to decrease the volume.
3. Dispensing procedure
a) For safety make sure that the discharge tube does not
point at the user or any other person. By using the built-in
FIX adapter it is possible to fit the dispenser as required.
Remove stopper cap by holding the discharge tube tight
with other hand.
b) Set the desired volume with the volume setting system.
c) Lift the dispensing piston up with the finger guard. Do
not touch the piston itself to avoid any unlikely contact with
chemicals. The piston stops at the volume set. The gradua-
tion on the glass cylinder is an additional optical control of
the volume set or air-bubbles. There is no graduation on
the PTFE-cylinder of the HF.
