Safety Instructions - Fisher Scientific Power Overhead Stirrer Manuel D'instructions

Safety Instructions

1. All operators must be familiar with the stirrer and should read this entire manual.
2. The stirrer must be securely fi xed to a stable support. Mount to a Fisher
Scientifi c Stand (Part Number 14-500-354 / 1298-7096) with a Fisher Scientifi c
heavy duty clamp (Part Number 14-500-357 / 1290-7106). If other stands or
clamps are used, the unit must be secure and can not fall if tipped up to ten
degrees from the vertical.
3. The stirrer must be supplied with the rated voltage. See serial plate.
4. CAUTION: This is not an explosion proof stirrer. Do not use with highly
fl ammable or explosive materials.
5. Spinning paddles or impellers can cause severe personal injuries. Operators
must use extreme care and good judgement when mixing at any speed. The
stirrer has higher torque capabilities than conventional stirrers.
6. All mixing paddles and impellers must be in good condition with straight shafts.
If the stirrer vibrates at high speeds check the paddle shaft for damage and repair
or replace it.
7. Extreme care must be taken when mixing chemicals so that no chemicals are
splashed outside the mixing vessel. Care must be taken when changing to faster
mixing speeds. On power up, the unit will display its set speed and will climb to
that speed when the start/pause button is pushed. Always start at lowest speed
if unsure of maximum safe speed.
8. Ensure that the mixing impeller does not contact the containing vessel.
9. Do not operate while standing in water. Keep the unit dry and do not immerse
any part, except the mixing paddle, into any liquids. Protect from splashing.
10. Ensure that no loose clothing, jewelry, or hair can become entangled in any
rotating parts. A fast spinning chuck can cause injury to an operator. Use chuck
guard provided when stirrer is in use.
11. Power can be interrupted to the stirrer by pressing the power button or by
disconnecting the mains cord. If rotating, this will cause the stirrer to stop and
will disconnect power to the stirrer's internal drive circuit.
12. Shaft rotation can also be stopped by pressing the start/pause button. This does
not disconnect power to the stirrers internal drive circuit.
13. Wear safety goggles and suitable clothing when operating the stirrer.
14. Repairs must be carried out by authorized technicians only.
