  • Page 12: Step 4 - Hinge Side Plate

    STEP 4 – Hinge Side Plate Install the 3/8-16 Threaded Handles into the Hinge-Side Side Plate. Do not tighten down all the way. Only tighten until the tip of the threads meet the inside face. Lower the hinge-side side plate onto the hinges. Use two 3/8-16 x 5/8” Long hex head bolts.

  • Page 13: Step 5 - Tool Arm Plates

    STEP 5 – Tool Arm Plates Install the tabs of (in order from front to back) the tool arm top plate and tool arm plates (3), into the slots of the hinge-side side plate.

  • Page 14: Step 6 - Motor Mount Side Plate

    STEP 6 – Motor Mount Side Plate Place the motor mount side plate onto the tool arm and tool arm top plates. Insert (4) 5/16-18 x 2-1/2” carriage bolts and secure with the 5/16 nylock nuts. If you overtighten the sides plates may bow outward.

  • Page 15: Step 7 - Tension Arm

    STEP 7 – Tension Arm Install the tension arm using the ½-13 x 1.75” carriage bolt, spacer, flat washer(s), and nylock nut. Tighten enough to eliminate side to side wobble. Overtightening can cause tracking issues. Additional washers are provided to fine tune the tracking.

  • Page 16: Step 8 - Gas Spring

    STEP 8 – Gas Spring Install the gas spring using 5/16-18 x 1.00” hex bolt, a flat washer on both sides of each eye, and nylock nut. Do not overtighten the gas spring bolts. It will bind and cause tracking issues and premature failure.

  • Page 17: Step 9 - Tracking Knob And Handle

    STEP 9 – Tracking Knob and Handle Insert 3/8-16 threaded handle into the tension arm (apply loctite). Install 3/8-16 threaded knob into the tension arm. This will be used to adjust tracking in operation. STEP 10 – Tracking Wheel Install the tracking wheel into the tracking arm using ½-13 x 3” hex bolt, nylock nut, and flat washer.

  • Page 18: Step 11 - Motor Install

    STEP 11 - Motor Install Tilt the chassis into the horizontal position. Install motor into belt side plate using 3/8-16 x 1 hex bolts and split lock washers. Make sure the feet of the motor are facing the rear of the machine.

  • Page 19: Step 12 - Drive Wheel Install

    STEP 12 - Drive Wheel Install Install drive wheel and secure with set screw. Align with other wheels to ensure proper tracking. The drive wheel should be approximately 7/16” off of the side plate.
  • Page 20 Additional Notes: - Make sure all wheel centerlines are aligned with each other to ensure proper tracking. There may be some variance due to tolerance stack ups. - To make sure the belt has enough tension, put the belt on all four wheels, pull and hold down the tension arm all the way, pull the platen arm out until the belt is tight, lock the platen arm in place, and release the tension arm.
