General Care
As with any precision test instrument, basic
common sense care will ensure a long life from
your Rotary Platform Abrasion Tester. Brush or
vacuum all particulate material and debris off the
instrument and surrounding work area. The
motor drive shaft cavity is prone to collect
debris. Periodically, remove the specimen
holder and vacuum this area using the suction
brush attached to the vacuum hose or Taber
Clean Up Hose.
Figure 82
Keep the vertical drive shaft of the Abraser and
the shaft holes of the specimen holders wiped
clean with a soft cloth. Drive shaft and holder
bores are machined to close tolerances. Never
force on a holder when dirt is present. This may
damage the holder bore and affect its accuracy,
or make it impossible to remove the holder
without damaging the motor.
DO NOT
allow any foreign particulate to get
into any of the bearing assemblies.
DO NOT
spill any liquids onto or into the
instrument or onto any of the bearing
assemblies. Wipe off all spills immediately.
DO NOT
operate the Rotary Platform
Abrasion Tester at freezing, sub-zero or
elevated, high temperatures. The
instrument is designed to operate in a
temperature range at or around room
temperature and in nominal room humidity.
Lubrication
The bearing assemblies are factory lubricated
and do not require regular lubrication.
Installing / Removing the Specimen
Holder
The specimen holder can be removed from the
instrument. This will allow for optional holders to
be used or to clean the motor cavity.
Each specimen table is designed with a drive pin
and ball plunger to provide a positive retaining
force that locks the specimen holder in place.
To remove the holder, place your fingers under
the edge of the holder and lift straight upward.
In the event that the holder cannot be removed,
DO NOT USE a tool to pry the table up. Contact
Taber Industries for further instructions.
Figure 83
With frequent specimen holder removal, the ball
plunger may need to be adjusted. Using a
screwdriver, tighten the ball plunger
approximately 1/16 turn. A silicone type spray
may be used to lubricate.
To install the specimen holder, align the bottom
opening with the vertical drive shaft of the
Abraser motor making sure that the ball plunger
and drive pin are aligned. Using a downward
force, press lightly on the specimen table until it
is fully seated.
Cleaning Vacuum Pick-Up Nozzle
Abraded material and debris may collect in the
vacuum pick-up nozzle orifices. Keep the
orifices clean of particulate by using a small
brush.
Replacing Quick Release Wheel Collet
The expandable collet for the Quick Release
Wheel Hub is manufactured out of a wear
resistant plastic, however it should be replaced
when the retaining lip shows signs of wear. An
indication of this wear is a rounding of the lip or
wheels are no longer held securely in place. To
facilitate this repair, a replacement collet kit is
available from Taber Industries.
