15 OPERATION. With the Power switch OFF, open the cover and check that the four platform screws are fully tightened before using the apparatus. CAUTION: WEAR PROTECTIVE GLOVES WHEN HANDLING GLASSWARE.. For proper high speed performance, fully load the shaker platform. The Shaker has been designed for precise dynamic balance when the platform is fully loaded with each flask containing 0% by volume of water. If the total number of cultures to be used are less than the platform capacity, install empty flasks in the remaining holders and fill each with water to 0% capacity. For speeds below 400 RPM, the dynamics of the system are less sensitive, and therefore less care need be taken in the loading procedure. Close the cover after loading.. Set both the Power and the Shaker switches ON. Set the speed/temp. selector switch to the speed position. Depress the locking tab on the Speed Control and adjust the Speed Control for the desired shaking speed and release the locking tab. 4.
