the handle bars are located on the inside of the frame. Remove both side plastic
housings, (Items #234 and #235, Drawing 5.1.1).
2. Remove the V-belt, (Section 4.3).
3. Close the rear chamber opening to its maximum, dial reading “0”. Remove the
timing belt (Item #327, Drawing 5.1.2), by pushing the belt tensioning arm, (Item

timing pulleys.
4. Remove the timing belt pulley, (Item #306, Drawing 5.1.2).
5. Move the chamber so that the lower pivot screws, (Item #112, Not shown, Refer to
upper pivot screws, Drawing 5.1.1), are lined up with the holes in the frame. Remove
both the right hand and left hand lower pivot screws. At this time you should secure
the chamber’s weight with pieces of wood. After securing the chamber, remove the
upper right and left hand pivot screws, (Item #112, Drawing 5.1.1), freeing the upper
connecting rods. By tilting the chamber slightly the lower connecting rods can be
dislodged. The chamber can now be removed by first moving it to the left so the drive
cylinder shaft clears the frame and then lifting it out from the machine. The rear
chamber assembly can then be placed on a convenient work surface.

slide the rear chamber tension cylinder, (Item #111, Drawing 5.1.1), out from the rear
chamber belt.
