MaxQ SHKE8000 Series Shakers
Make sure the shaker is in place, level and the platform installed. With the
unit turned on and empty, set the speed to 300 RPM. Kneeling in front
of the shaker, lightly touch the lower left and right corners of the cabinet.
If one side seems to vibrate more then the other, raise or lower the leveling
foot using the 3/4" open end wrench supplied in the parts bag. Continue
this "fine tuning" until the vibrations are reduced as far as possible. Ensure
locking nuts are secured when complete.
Caution Do not extend leveling feet more than
1/4 inch from the bottom of the unit. When the
unit is leveled and tuned, with the leveling feet
locked in place, the adjustment and locking nuts
should be no further apart than 1/4 inch.
Each platform is adjusted to fit the unit with which it is shipped. In the
instance of replacement or additional platforms, adjustments may be
required. To check for undue platform vibration noise during operation,
see the steps following.
1. Make sure the platform handle is in the vertical position and the door
is closed. The unit should also be leveled and tuned.
2. With the unit turned on and empty, set the speed to 300 RPM. Allow
the shaker to run for several minutes. If the vibration is normal, return
the unit to service. If not, continue to Step 3.
3. Remove the platform from the chamber. At the back
of the platform are two tapered pins (Figure 4-10).
4. Loosen the nut closest to the platform. Turn the
center nut slightly to extend the pin away from the
platform. A quarter-turn or less is a good first test.
5. While holding the center nut, tighten
the nut closest to the platform back
against the pin mounting block.
Install the platform into the
chamber. Note pin locators (Figure
4-11) on quick-release platform.
6. With the unit turned on and empty,
set the speed to 300 RPM. Allow shaker to run for several minutes. If
the vibration is normal, return the unit to service. If not, repeat Step 4.
