1、_Hilka Confidential Page 1 of 6 Grass TrimmerInspection Procedure Grass Trimmer (275W)PurposeTo define the method used to inspect and test hand held mains powered grass trimmers, to ensure consistent manufacture and thus assure Hilka Tools (UK) of the inherent safety and reliability of these items.S
2、copeGrass trimmers (Hand Held) capable of accepting a variety of nylon lines which rotate and “flail” the grass. These units will be powered via a 13Amp plug directly from a 230v mains source. Note: the cable must be a minimum of 6m long.Associated documentsInspection Report Form : 001 and Form : 00

10、is selected. Then all 125 units are subjected to the test.Test 1: Insulation ResistanceMeasured 100Mohms between live andbody, with the switch ON. DC voltage applied 500V. (Pass range: 7Mohms to 100Mohms)Test 2: Electric StrengthBetween live plug pins and body, with the switch ON Applied voltage 400
11、0V AC for 2 Secs. Overcurrent trip relay 5mA. Result, no breakdown or flashoverRecord the results for each unit tested (Pass or Fail)Record the calibration date on the machine(s) and equipment used and review the calibration certificate(s). Confirm and record these dates.The equipment MUST be within
12、 calibration prior to commencing the tests.In addition review the daily check procedure used by the factory and record the results. Check the daily check record sheet and confirm machine identity codes and certificates. (only applicable when conducting outgoing inspection)General Inspection - 13 AMP
