Safety Instructions
Each operator should read all instruction before using this device.
The stirrer must be securely xed to a stable support such as the provided stand.
If other stands are used, the unit must be secured such that it will not fall if tipped.
CAUTION: This is not an explosion-proof stirrer. Do not use in a highly
ammable or explosive environment.
Spinning paddles or impellers can cause severe personal injuries. Operators must
use extreme care and good judgment when mixing at any speed.
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 if needed.
Extreme care must be taken when mixing chemicals to ensure that no chemicals
are splashed outside the mixing vessel. Care must be taken when changing to
faster mixing speeds.
Ensure that the mixing impeller does not contact the containment vessel.
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 unit and operator from
splashing.
Ensure that no loose clothing, jewelry, or hair can become entangled in any
rotating parts. A fast spinning chuck can cause injury to operator.
