(UL) under its Follow-Up Service for this category within the limitations given below and in the Scope section
4、of this Outline of Investigation. They are subject to revision as further experience and investigation may show is necessary or desirable. B. The observance of these requirements by a manufacturer is one of the conditions of the continued coverage of the manufacturers product. C. A product which com
5、plies with the text of this Outline of Investigation will not necessarily be judged to comply with the Outline of Investigation if, when examined and tested, it is found to have other features which impair the level of safety contemplated by these requirements. D. A product employing materials or ha
6、ving forms of construction which conflict with specific requirements of the Outline of Investigation cannot be judged to comply with the Outline of Investigation. A product employing materials or having forms of construction not addressed by this Outline of Investigation may be examined and tested a
7、ccording to the intent of the requirements and, if found to meet the intent of this Outline of Investigation, may be judged to comply with the Outline of Investigation. E. UL, in performing its functions in accordance with its objectives, does not assume or undertake to discharge any responsibility

11、s” is replaced by ”routers and trimmers.” 2 Components This Section of Part 1 is applicable. 3 Undated References This Section of Part 1 is applicable. 4 Units of Measurement This Section of Part 1 is applicable. 5 Glossary This Section of Part 1 is applicable except as follows: Add definitions: 5.1
12、01 ROUTER - A tool designed to be fitted with a rotary cutter for cutting slots in wood or shaping the edge of wood. Note: Routers may have one or more handles to help control the tool during use. 5.102 TRIMMER - A tool designed to be fitted with a rotary cutter for trimming the edge of a plastic la
13、minate sheet. wood veneer or similar materials fixed to a substrate. Note: A trimmer is normally gripped around the body of the tool and does not have additional handles or gripping areas.

16、th This Section of Part 1 is applicable. 15 Construction This Section of Part 1 is applicable except as follows: 15.14 This paragraph of Part 1 is not applicable. Add paragraph: 15.101 A router having a mass exceeding 2 kg (5.4 lb-mass) shall be provided with two handles. For other routers and for t
17、rimmers, only one handle is required. A handle or handles shall be shaped or located to reduce the risk of unintentional contact of the users hand with rotating parts. When the gripping area of the handle is provided with a shroud or barrier at its end adjacent to the body of the tool, it is conside
18、red to reduce the risk of unintentional contact of the users hand. Adjustment elements capable of being readjusted while the tool is operating, such as a revolving depth gauge, shall be located so that they are unable to be contacted. The base plate of a router shall surround the cutter so as to red
19、uce the risk of unintentional contact with the cutter. Compliance is checked by inspection. Note: The mass of the router is to be measured with attachments, but without accessories. Examples of an accessory are a mandrel, a cutter and an airhose. 16 Noise Emission This Section of Part 1 is applicable.
