General visual inspection
1 Ensure the appliance to be safety tested has no obvious
mechanical faults and is free from external damage.
2 Inspect the mains lead for any damage, defects or loose
terminals in the accessories, connectors, plugs or outlet
sockets. Common faults encountered:
a) Frayed, cracked or otherwise damaged mains lead.
b) Exposed conductors and/or covered by insulation tape.
c) Abrasions in the outside insulation jacket.
d) Mains lead anchorage at plug or appliance entry.
3 Check that any controls, alarms and replaceable protective
devices accessible to the user, are of correct rating and in
good working order.
4 Inspect all switches and speed controls for mechanical
operation; ensure switches and controls are clear of any
obstruction, e.g. filings, swarf, metal particles, grease, etc.
5 Confirm all identity tags/labels etc. pertaining to the
frequency of safety testing are correctly attached and
records of all test/inspections are kept to ensure the safety
integrity and history of the appliance.
6 Unroll extension leads and inspect as above.
Identify the type of appliance to be tested
Examine the appliance to be tested and identify whether the
appliance is an earthed appliance, a double insulated appliance
or an extension cord.
Earthed appliances will always have an earth pin on their plug,
and may have exposed metal components.
Double insulated appliances may be identified by the double
insulation symbol, and/or by the absence of an earth pin on
a moulded socket (if not misssing or deliberately removed).
Note 1
: Many double insulated tools are colour coded blue.
Note 2:
If any doubt exists about the Class of an appliance
(Class I or II), the appliance should be tested as an earthed
appliance first (see also OTHER APPLIANCE menu).
Preparation of an earthed appliance to be safety tested
1 Switch any/all switches ‘ON’.
2 Set any speed control or thermostat to ‘FULL ON’
(Maximum speed).
3 Preparation for earthed appliance to be safety tested is now
complete and may be connected to the
SafeTcheck.
(see Safety Testing Earthed Appliances)
Preparation of a double insulated appliance to
be safety tested
1 Switch any or all switches to the ‘ON’ position.
2 Set any speed control or thermostat to ‘FULL ON’
(Maximum speed/temperature).
3 If not in Probe Mode, preparation for a double insulated
appliance to be safety tested requires the appliance to
be wrapped in a stainless steel cloak taking care to make
contact with all metal components and the exterior of the
appliance where hand contact is normally possible.
4 The double insulated appliance is now ready to be safety
tested and may be connected to the
SafeTcheck.
(see Safety Testing Double Insulated Appliances)
Note:
The above description regarding the inspection
and testing of electrical appliances is a guide only.
Please refer also to the current standard AS/NZS 3760.
WaRNINg
Upon completion of a safety test and subsequent
removal of test lead and/or stainless steel cloak, please
ensure all switches, speed and thermostat controls are
returned to their ‘OFF’ or minimum position.
