  This tool can quickly start up while connected to an electrical supply causing serious personal injury. Always disconnect the  

Tire Machine from the electrical supply before making adjustments or performing maintenance.

EYE INJURY HAZARD! 

  Moving/rubbing components under great pressures can suddenly eject particles at high velocity. Always wear ANSI approved  

eye protection when operating this equipment.

  Excessive air pressure can cause tool to explode resulting in tool damage and personal injury. Do not exceed 145 psi [10 bar] of  

tool inlet air pressure.

BURST HAZARD! 

  Disconnect compressed air source and electrical supply before servicing Tire Machine.

ADJUSTMENTS

The Mount/Dismount Shoe positioning was adjusted at the factory 
so that the inner curve will be concentric to the outer edge of wheel 
rims with the 

“Duckhead”

 and 

“Ducktail”

 sections at equal dis-

tance from any size wheel rim diameter. With use, this may require 
periodic checking and adjustment. To do so:

•  Place a wheel face-up on the Turntable 

“jj”

.

•  Depress the Rim Clamp Pedal 

“mm”

 to clamp it in place 

(FIG 6)

.

•  Release the Lock Lever to unlock the Slide Shaft 

“bb”

.

•  Allow the Mount/Dismount Shoe 

“Ducktail”

 Plastic Glide 

[G]

 to stop just above the face of the rim then lock the  

Slide Shaft.

•  Rotate the Wheel Diameter Adjustment Knob 

“nn”

 inward 

or outward to determine the distance of the “Duckhead” 
Replaceable Plastic Glide 

[H]

 of the Mount/Dismount  

Shoe in relation to the edge of the wheel rim bead area 

(FIGS 9 & 10)

.

•  Check for any variation in distance from the 

“Duckhead”

 

and the 

“Ducktail”

 ends of the Mount/Dismount Shoe and 

the outer edge of the wheel rim.

•  If the distances are unequal, adjustment is required. 

To adjust:

  -  Loosen the large bolt at the underside of the Mount/ 

  Dismount Shoe with a 16mm wrench (not included)  
 

(FIG 15)

.

  -  Loosen the set-screw on the 

“Duckhead”

 side with a  

  6mm hex key (not included) 

(FIG 15)

.

  -  Using the same 6mm hex key, turn the 2 adjusting  

  screws on the inner side in or out to rotate the Mount/ 
  Dismount Shoe as required to bring it into alignment

  

  (FIG 16)

.

  -  Re-tighten the set-screw and the large bolt to lock in  

  the adjustment and check once again.
