Conveyor Belt Tracking
Belt tracking adjustment may be necessary during
Abrasive belt tension must be properly adjusted before adjusting the tracking. Adjust the belt tracking while conveyor belt is running at its fastest speed.
Tighten hex nut (A, Fig. 3) on the side the belt is drifting towards, and loosen hex nut on the opposite side. Use the attached wrench (B, Fig. 3) to adjust the hex nuts. Note: Adjustment should be made in 1/4 turns of the hex nut. Allow time for the belt to react to the adjustment. Do not over adjust.
Dust Cover
To open dust cover push in on the knob (C, Fig 3) and lift.
Checking Drum Alignment
The sanding drum comes preset from the factory. If a problem with drum alignment occurs follow the below listed instructions.
1.Push in and lift knob (C, Fig. 3) to open cover and remove abrasive strip. If you are unsure how to do this see the “Wrapping Abrasive Strips” section page 10.
2.Use a metal straight edge, or ruler as a thickness gauge (D, Fig. 4). Insert the gauge between the drum and conveyor bed on outer end of drum.
3.Open dust cover and lower sanding drum while slowly rotating drum by hand until the drum lightly contacts the thickness gauge.
4.Remove thickness gauge and place under the drum at opposite end. If drum does not contact the thickness gauge to the same degree as the other end of the drum, alignment is necessary.
Aligning the Drum
1.Loosen the four hex cap bolts (E, Fig. 5) two in front and two in back.
2.Lay the thickness gauge under the drum lengthwise.
3.Adjust the knob, (F, Fig. 5) until drum contacts the gauge equally along its surface. Turn the adjusting knob clockwise to raise
outboard end of drum, and counter- clockwise to lower outboard end of drum.
4.When drum is parallel to the conveyor tighten the four hex cap bolts.
