7.0 OPERATIONAL PRECAUTIONS
7.1 SAFETY
LLOYD INSTRUMENTS testing machines are inherently safe if used properly. Operators must be
made aware that:-
1 High physical forces are involved.
2 Samples under test may shatter.
3 Electrical power supplies are involved.
4 The following must ALWAYS be brought to the attention of any operator before they are allowed
to use the machine. Hands, ngers and other parts of the body must at all times be kept well
away from the moving crosshead. Operators should be particularly careful when moving the
crosshead to insert test samples, to ensure that no part of the hand could be accidentally com-
pressed as the crosshead and grips are jogged into position.
5 NEVER drive the machine from a computer when anyone else is working on or near the ma-
chine.
6 If there is any danger that liquids may be spilt during tests, operators must use a drip tray (which
is available from LLOYD INSTRUMENTS) to guard against the possibility of any spillage enter-
ing the machine and giving rise to electrical or other hazards.
7 Take extra care when operating in compression mode where specimens may burst, shatter or y
out from between the platens. Operators should STAND CLEAR during testing. Splinter shields
are available in various options to suit specic requirements.
8 All operators must receive adequate training in basic operation before being allowed to use the
machine. Additional copies of this manual are available from AMETEK Inc.
9 Operators must ensure that the Emergency Stop Button is never obstructed.
10 Operators must ensure that other personnel working in or near the area are made aware that
testing is taking place and that they should not approach the machine while it is in use.
11 Operators must ensure that the machine is regularly serviced and calibrated by LLOYD IN-
STRUMENTS, or one of their accredited service dealers.
12 To maintain EMC compatibility, the machine should only be used as prescribed in this manual.
Connecting cables, plugs and sockets should be inspected regularly. Cables damaged or worn
in any way should not be used. Accessories and accessory connecting leads, if suspect, should
be replaced only with a LLOYD INSTRUMENTS approved replacement. Failure to observe this
may cause your machine to infringe the EMC legal requirements.
13 NEVER attempt any form of machine maintenance without disconnecting the mains electrical
supply.
14 NEVER attempt to test any samples with a type of grip or other accessory, which is not de-
signed for that particular test. Never use grips or the machine for tests in excess of the stated
load limits. A comprehensive range of alternative grips, together with an applications advisory
service, is available from LLOYD INSTRUMENTS and their accredited dealers.
