The base weights are designed with a carrying handle and weigh less than 16.8 kg
each. Refer to the Lifting Operations and Lifting Equipment Regulations 1998 (LOLER) for
guidance on safe lifting and be certain to only lift what you are comfortable with.

For safe zoning and cordoning off working areas measure a two metres distance from the desired area. Position the base at this point, placing it down outwards, away from the body as shown, with the D-marc™ logo facing away from the hazard.
3
Insert the D-marc 105 upright into base ensuring the integrated hook for the chain is on
the side facing the hazard. The upright base plate must fit flush into the weighted base.
4
Lift the base to reveal the underside.
5
First place the repair washer, then the spring washer & finally the wing nut onto the
exposed threaded pin & hand tighten until the flat plate on the post fits snuggly against
the rubber base.
6
Thread the first link on the chain through the top section of the upright and position onto
the integrated hook. Continue by feeding the opposing end of the chain through the
adjacent upright until the sag in the chain is approximately 100 mm below the horizontal then
attach the intermediate link to the hook.
