Model 1700 / 1750 Rotary Platform Abraser

Operating Instructions ver. 1.0
p/n 135505
To operate with a load of 500 gram, slide the
auxiliary weights marked 500 g onto the left and
right auxiliary weight mounts.
To operate with a load of 1000 gram, slide the
auxiliary weights marked 1000 g onto the left
and right auxiliary weight mounts.
NOTE:
For simplicity sake, each auxiliary weight is
marked with the total load that will be exerted on the wheel
and is the combined total of the weight and the abrading
arm. The weights marked 500 g are actually 250 grams.
Likewise, the weights marked 1000 g are 750 grams.
NOTE:
Wheel
l
oad references are
per arm (not
combined). The load that is specified in most test methods
does not include the mass of the wheel.
NOTE:
An optional counterweight kit is available when
less than 250 g load is required.
Vacuum System
Models 1700 / 1750 include a Taber vacuum unit
that includes a heavy-duty motor and life-lubricated
sealed bearings. When the vacuum power
connection is plugged into the rear of the abraser
housing, the vacuum will automatically turn on
when a test commences and shut off at the end of
the programmed test cycles. A flexible rubber
suction hose connects it to the Abraser.
Vacuum Nozzle Height Adjustment
– To adjust
the gap between the vacuum nozzle and test
specimen, rotate the precision adjustment knob.
Each full rotation of the knob represents a 1 mm
height adjustment. All adjustments should be made
after the specimen has been mounted.
WARNING:
When testing flexible materials, ensure
the suction from the vacuum nozzle does not lift the
specimen. Any contact between the specimen and
vacuum nozzle during the test, will cause additional
wear that may influence the test results.
