5. Section 4 Accessories A Introduction The Reliant series floor scales have several accessory options available These accessories are Bolt down plates Ramps and Bumper Guards B Bolt Down Plates Bolt down plates are used to keep the scale from sliding or moving when loads are applied The plates are bolted via anchors at each of the scale s feet 1 Installation a Place the platform in position b Place the bolt down plate under the foot plate edge extending out from under the scale C Drill the two 2 holes using a hammer drill Insert anchors with the nut and washer already ON Tap the anchor into the hole then tighten the nuts securely Repeat this process for each plate used Note If ramps are NOT installed and bolt down plates are needed a set of four bolt down plates will be required C Ramps Each mild steel ramp accessory comes with two integral bolt down plates and four anchors 1 Installation a Place the ramp in position then lift and set the platform feet into the bolt down plate holes b Drill the two 2 holes using a hammer drill Insert the anchors with the nut and washer already ON Tap the anchor into the hole then tighten the nuts securely f two ramps are installed NO other bolt down plates are needed e If one ramp is installed a set of two bolt down plates is needed e Only two ramps total may be installed on opposite sides of a scale platform 10 06 9 50783 Issue 2 D Bumper G
