Maintenance
Section 6
Note The shaking mechanism is equipped with sealed ball bearings which
do not require further lubrication or adjustment.
Note Make no attempt to service or repair a Thermo Scientific product
under warranty before consulting your distributor. After the warranty
period, such consultation is still advised, especially when the repair may be
technically sophisticated or difficult.
If assistance is needed beyond what the distributor can provide, call the
Technical Services department. No merchandise, however, should be
returned without prior approval.
Wash the exterior of the unit with a soft cloth using a solution of mild
soap and water, rinse off with clean water and dry thoroughly.
Warning Disconnect plug from electrical outlet before attempting any
maintenance or repair of the unit.
The gas springs should be checked periodically, and ideally every six
months. The opening force, as measured from the front lip from a closed
position, should be below 100 N (22.5 lbf) maximum. If the force is
above this value, the gas springs should be replaced. If a force
measurement is not possible, the gas springs should be replaced every two
years.
1. Remove the platform by loosening the 4 thumbscrews, remove ribbed
mat, remove the 9 smaller screws on the platform mounting plate,
there are 3 Phillips screws at each of the 3 bearing mounts. Refer to
Figure 6-1.
2. Position the platform mounting plate atop the shaker body and install
all 9 screws by hand until they are finger-tight only. Rotate the speed
control fully counterclockwise (OFF) and plug the unit into an outlet.
Rotate the speed control knob slowly in the clockwise direction to
allow the shaker to orbit at its slowest speed.
