4.
Disconnect the plastic Water Hose (38) @ the ¼” 90 deg. elbow (40), by pressing the end of a flat head screwdriver
against the end of the black plastic elbow , force parallel with the tube , in the direction of the elbow. While doing this, pull
the plastic tube out of the elbow.
5.
Remove the Roller Frame (1) with the blade (36) from the Gearbox Housing(16)
6.
Remove the Blade Guide (18A), or (2) spacers(18B),(when optional blade guide is not purchased), by removing (2)
¼” HHCS’s (29,21,3) from Roller Frame.
7.
Loosen (4) Rollers: by loosening each ¼” HHCS(6,4,5), then turning ea. Ecc. shaft (7) slot to 3 o-clock/9 o-clock
position from the blade, with a flat head screw driver.
8.
Blade will now be free to slide out of Roller Frame slot opening.

Ref.: Drive Wheel Removal and Installation Diagram, Figure 4-1, pg. 12:
Remove the Drive Wheel (36) from the Gearbox Housing (16) by loosening the (2) #10 SHCS’s (23), with a 5/32”
(156”) hex. wrench. In order to keep the Drive Wheel from turning while loosening the (2) screws, hold the Drive
Wheel Mounting Flange (15) around the outside edge with a vice grip pliers.

Blade and Drive Wheel Installation
(continued from above step).
1.
Slide the Mounting Flange (15) onto the New Drive Wheel (36) and slide both onto the drive shaft of the Gearbox
Housing (16).
2.
Insert the (2) lock washers (24) and (2) #10 SCHS’s (23) and tighten with a 5/32” (.156”) hex. wrench. In order to
keep the Drive Wheel from turning while tightening the (2) screws, hold the Drive Wheel Mounting Flange (15)
around the outside edge with a vice grip pliers
3.
Insert the New Blade (36) into the Roller Frame (16) slot opening, with the blade side grooves positioned within the
(2) Guide Rollers item(2). Located on the far side while facing from the motor side.
4.
Adjust the (4) Eccentric Shafts (7), so that the Blade is centered within the blade slot opening of the Roller Frame (1),
making sure the side grooves of the Blade are engaged within the Guide Rollers(2).
5.
Tighten the (4) Eccentric Shafts (7), so that the (4) Rollers exert enough force on the blade, such that when the blade
is turned by hand, the rollers rotate. Also, while turning the blade by hand, when you put your thumb on each roller,
you can stop the rotation of that roller. This assures that the contact between the blade and the rollers is neither too
loose or too tight.
6.
Tighten the (4) ¼” HHCS’s (6), one on each Roller. This locks the Rollers into position.
7.
Position the Roller Frame (1), with the blade in position, onto the Gearbox Housing (16), so that the “V” groove on
the inside diameter of the Blade engages with the Drive Wheel (36) on the Gearbox Housing.
8.
Adjust the Knurled Knob Adjusting Screw (41) so that the Blade “V” seats tightly against the Drive Wheel “V”. This
contact provides the frictional force necessary for the Drive Wheel to rotate the blade.
9.
Tighten the (2) 3/8” HHCS’s (25, 20, 44) that attach the Roller Frame to the Gearbox Housing. This locks the
position of the Drive Wheel to the Blade.
10.
Insert the Blade Guide (18A), or the (2) spacers (18B), into position of the Roller Frame (1) with (2) HHCS’s
(29,21,3).
11.
Insert the plastic Hose (38) into the ¼” 90 Elbow (40).
12.
Run the RingSaw (without water), and observe the Blade rotation and (4) Roller’s rotation:
