GB-21RANSOMES MATADOR 71 series: BN/CFSAFETY, OPERATORS, MAINTENANCE AND PARTS MANUAL8 ADJUSTMENTS8.1 HEIGHT OF CUT ADJUSTMENTThe cutting height is determined by the position ofthe front rolls in relation to the bottom blade, variationof this height is made by adjusting the front roll. Arange of cut between 6mm and 28mm can beachieved with the adjustments explained below.The height of cut bar (A Fig. 8.1) is used toaccurately set the height of cut. The bolt in (A) ispositioned so that the head of the bolt is hooked overthe lip of the bottom blade. The bar rests against boththe front (C) and the rear (B) rolls. The measuredheight of cut would be from the underside of the headof the bolt to the surface of the setting bar.It is important when using the bar to set the bolt tothe desired height of cut first and then to try toposition it over the lip of the bottom blade. If it doesnot fit snugly then the front roll will requireadjustment.This procedure should be carried out at both ends ofthe bottom blade in order to set it parallel to the rearlandroll.SETTING THE HEIGHT OF CUTThe cutting height is determined by the position ofthe front roll in relation to the bottom blade; variationof this setting is made by adjusting the front roll bymeans of a handwheel (C Fig.8.2b):The height of cut range is between 6mm (1/4in) and28mm (1 3/32in).To raise the height of cut the roll must be lowered byturning the handwheel clockwise.To lower the height of cut the roll must be raised byturning the handwheel anti-clockwise.8.2 ALIGNING THE FRONT ROLLS (Fig.8.2)Should the front roll become out of line with thebottom blade, adjust accordingly:1. Slacken the locknut (A) on the adjustingswivel.2. Place a straight edge between the front rolland landroll, and check the variation in themeasurement between the bottom bladecutting surface and the straight edge atboth sides of the machine.3. Adjust swivel nut (B) to reset the front rollso that the measurement between thebottom blade cutting surface and thestraight edge is the same both sides.4. Retighten the locknut.Fig. 8.2bFig. 8.1a
