Gilson Company, Inc.
Since most test specifications require no more than sev-
eral hundred grams of sample for fine aggregates, using
8in round sieves is sufficient. A Gilson Sand Attachment
Accessory for round sieves is available for the Testing
Screen. It provides an inexpensive method when occa-
sional tests in the fine series range are required. If fine
series tests are made on a routine basis, use equipment
that is specifically designed for fine materials. Gilson offers
a complete line of sieve shakers for this purpose.
The capacity of the Gilson Testing Screen is suitable for
most laboratory test sizing work. For field laboratories
where mobility is important, Gilson offers a Porta-Screen
For large-scale mass separation jobs involving hundreds
of pounds of material, and for automated testing, use the
Gilso-Matic
. See a Gilson Catalog for further information.

note: The person performing maintenance and/or
repairs on the Testing Screen is responsible for safety
and is required to read and understand the safety
instructions in this manual prior to commencing work.
All shields, guards and other safety devices must be
properly replaced and secured upon completion of
work. Only parts supplied and/or approved by Gilson
are acceptable for use on the machine.
Most sample dusts are abrasive by nature. Daily lubri-
cation and cleaning of the Testing Screen takes only a
few minutes, and will greatly extend its service life and
reduce down time.
WArninG!:
Always unplug or disconnect the
Testing Screen from its power supply and lock out
the connection before performing any maintenance
or repairs.
5.1 Lubrication
Each Testing Screen is fully lubricated and test-run by
the manufacturer before it is shipped. However, periodic
lubrication is required.
Use a high-quality grease to lubricate parts listed below.
Wipe away excess grease and dirt from around parts
after lubrication.
a. At least daily, lubricate the wrist pin assemblies at the
lower ends of the connecting rods.
Access: Slot under front of top cover.
b. Lubricate the following parts on a regular basis, but
not as often as the wrist pin assemblies:
•
Upper connecting rod bearings.
Access: Holes in front of top cover.
•
Lower threaded blocks, TS-2.
Access: Panels on sides of machine case.
5.2 removal of top & Side/Back Covers
Use this procedure whenever you need to remove the cov-
ers for repair or maintenance of your Testing Screen.

WArninG!:
Disconnect the machine from its power
source and lock out the connection prior to performing
maintenance and/or repairs.
5.3.1 V-belt
Periodically check the Testing Screen's V-belt for
wear, tension, and alignment. The belt should be
snug, neither too tight nor too loose. It should deflect
about 1/4in (6mm).
A worn, loose, tight, or misaligned V-belt can adversely
affect the operation of the Testing Screen. A good fit
assures longer life, less bearing wear, and quieter
operation than a belt which is too tight. A loose belt
may cause the unit to run too slowly or to slip.
