ume mode, the pump must be stopped first.
5. Maintenance
No special maintenance is required other than keeping the pump 11 clean and
dry. Avoid liquid spills that may find their way into the electronics.
A small container of grease is provided for periodic lubrication of the lead
screw. A small bottle of oil is provided for periodic lubrication of the two steel
guide rods. It is important to keep these guide rods clean and oiled.
6. Protecting Small, Fragile Syringes
The Pump 11 will hold microliter size syringes down to 0.5µl size. These
small syringes have fine wire plungers that may be damaged if allowed to bot-
tom out. The Pump 11 is equipped with an adjustable stop collar on one of
the guide rods. Use the provided hex wrench to position and lock the stop col-
lar to prevent damage to small syringes.
