3.0 Maintenance Guide

3.3.2 Backgauge Leadscrew

With the top cover ON, place machine on a flat level surface on it’s left side and remove bottom

cover. Use any brand-name type of grease or light oil to lubricate backgauge leadscrew (Figure 4). It

may be helpful to use a small brush to apply grease. Note: the leadscrew may be lubricated with

grease or oil. Oil has a tendency to run off and must be lubricated more frequently; grease tends to

collect paper dust and must be cleaned off periodically.

3.4 Adjustments

Some of the following tests require the machine to be operational for

checking and adjusting. Be very careful that tools and other people are clear of moving parts and that

the cutter is not accidentally operated while adjustments are being made. Whenever possible,

disconnect the power and lock it out (see SAFETY PRECAUTIONS, page 4) unless the directions

specifically require the machine to be powered.

3.4.1 Squaring the Backgauge

To test if the backgauge is square, place a small lift of paper against the left side of the backgauge

(but not against the side guide) and make a cut. Now, leave the backgauge in the same position, flip

the lift over and push it against the right side of the backgauge (but not against the side guide). Make

another cut to see if any of the paper will trim off (Figure 5). Run two checks, one starting on the left

and moving to the right; the other, moving from the right to the left. If paper is trimmed in either

sequence, the backgauge is out of square.
