Changer Placement: We recommended assembling the tire changer before mounting to the floor so the user will better understand the space needed for the changer and changer tools. We
recommend providing a 5-foot clearance circle from the center of the frame assembly, and 12” clearance from the rear of the machine to any wall. See Figure B.
STEP 1 Attach Stand Square Base (B) and Stand Triangle Top (C) to Stand Post (A) Using (16) Screws (S). There are 8 screws for each plate, but only 4 of each are shown on the diagram due to a
design revision. Make sure all threads of all screws are started before tightening. The notch in the Stand Triangle goes towards the front. The ATV bead breaker accessory tab on the stand post
should be pointed to the rear of the changer to keep it out of the way unless you will be using the ground-level ATV bead breaking upgrade.
STEP 2 Attach 3 frame arms (D) using 2 "Y-plates", fastening with 6 screws (Z) on top and bottom.
STEP 3 Attach Frame Assembly (D) to the Stand Assembly in the orientation pictured, using (3) 1/2" hex bolts (Q) and washers (R). Use a 3/4" (19mm) wrench to tighten.
STEP 4 Secure Tool Collar (N) onto the Back Post (E), approximately 1/8" below Swivel Tee by tightening 2 set screws (P).
STEP 5 Slide Clevis Collar (G) onto Back Post (E) and leave loose. This part needs to spin freely.
STEP 6 Secure the Stop Collar (F) onto Back Post (E) 1/8" below Clevis Collar (G) by tightening 2 set screws (P).
STEP 7 Slide Back Post (E) into the top of the Frame (D) so that it extends 2" below rear frame arm collar. Tighten (4) set screws (P).
STEP 8 Attach Bead Breaker Arm (H) to the Clevis Collar (G) by first removing the 3/4" shoulder bolt (V) and 2 washers. Place one washer on either side of the break arm tab, hold the end of the
break arm and washers together and align in the slot, followed by inserting the shoulder bolt until the threaded end can be screwed into the threads and tightened.
STEP 9 Attach Bead Breaker "Tee" (I) to the Bead Breaker Arm (H) using the 1/2" shoulder bolt (W) and Nylock nut (X). Verify proper alignment of the tee so that the No-Mar markings on the non-
marring wedges face forward when the break arm is raised. Use 5/32" Allen Wrench and 7/16" wrench on Nylock nut to tighten. (There will be play in this joint -- this is by design!!!)
STEP 10 Insert Slide Arm (J) in the opening of the Swivel Tee as shown with the larges holes at the front and oriented up and down. Tighten the Locking Knob (T) to secure the slide arm in
position. Do not over-tighten. The upper arm should swing side-to-side freely at this time.
STEP 11 Insert the Center Post (K) into the hole on the end of the Upper Arm (J) with the pin pointing down. Hold the center post in position using the Center Post Knob (Y) on the side. There is a
hole in the center of the “Y-plate” on the Frame Assembly where you can engage the pin from the center post for single-sided swingarm wheels, automotive wheels, or any wheels with a large
axle opening (the center post will not fit through all wheels, for such wheels the eccentric pin should be engaged in the bearing).
STEP 12 Mount the tire changer to a suitable floor using anchors.
STEP 13 Compare your assembled changer to the photo in Figure C to verify everything was done correctly.
STEP 14 Please visit the Video Library on our website to familiarize yourself with tire changer use and technique prior to changing your first tire.
