cated inside the tip holder. In this case, the 0-
ring can not be accessed for maintenance.

mended to grease the piston slightly using the

piston.

10. TROUBLE SHOOTING
A quick inspection of the pipette referring to the
below questions may help you isolate the problem.
- ls the push button rod straight?
- ls the push button free of chemical damage?
- Are the volumeter digits clear and easy to read?
- Can you set any volume in the useful range?
- Can you set the maximum volume?
- Does the volumeter operate smoothly without
hitching?
lf the answer to any of these questions is NO, the
pipette probably has been damaged as the result
of a mechanical shock or chemical damage, in
which case it should be returned to your supplier
