~ Fixed guards that are to be removed as a part of maintenance procedures, described in the operator's manual, shall be fixed by systems that can be opened or removed only with tools. These guards fixing systems shall remain attached to the guards or to the machinery when the guards are removed. Where possible, fixed guards shall be incapable of remaining in place without their fixings. <5I

Articulated machines shall be equipped with an articulated frame lock according to ISO 10570:2004.

5.14.6 Sharp edges and acute angles

Sharp angles and acute angles shall meet the requirements defined in ISO 12508:1994 in the areas which can be accessed during operation and daily maintenance, except for the area of the attachment. See also 5.3.1.6.

5.14.7 Fenders

Earth-moving machinery with a design speed according to ISO 6014:1986 greater than 25 km/h shall be equipped with fenders according to EN ISO 3457:2003 that protect the operator's station from debris ejected by the tyres or tracks if the risk exists.

5.15.2 Retrieval

Retrieval points shall be provided at the front and/or rear of the earth-moving machines according to ISO 10532:1995.

Attachment points for retrieving of the machine shall be described in the operation manual as well as permissible forces and correct use.

5.15.3 Tie-down

To transport earth-moving machinery safely, tie-down points to anchor the machine e.g. on a trailer, shall be provided and clearly identified on the machine (see ISO 6405-1:2004, symbol 7.27). Instructions for their use shall be included in the operation manual.

5.15.4 Lifting

Lifting points shall be provided and be designed for the operating mass in the heaviest configuration and shall be clearly identified on machines or subassemblies that are to be lifted in one piece.

The method of lifting heavy attachments, components and machines shall be described in the operation manual (see 7.2).
