wheel. It should slip into the center hole with no play. If it is not a snug fit, it
should be replaced.
2. If the vibration is still present with the wheel removed, the problem lies with
the aluminum back plate (P/N M222 for MT10, P/N M221 for MT12 and
MT15). The backing plate must be removed and cleaned of all plaster, or
replaced. To remove the aluminum back plate a Back Plate Removal Tool
(item M816) is needed. Please refer to the "Accessories" section of this
manual.
INSTALLATION OF REPLACEMENT WHEELS
1. Unplug the model trimmer from the electrical power source, remove the door
secure knob (A), and swing the door open wide.
2. Loosen the three screws and remove P/N M095 Lock Button (B). The old
wheel may now be removed from the trimmer. Remove the P/N M096 Cork
Gasket (C) from the backside of the attach button, and replace it with the new
gasket included with all Foster replacement wheels. If only reversing the
existing wheel or using a wheel from a source other that Ray Foster, make
sure that the existing cork gasket is in good condition, if not, a new one is
needed. This is essential in preventing slippage of the abrasive wheel.
3. Install the new replacement wheel flush with the aluminum back plate,
aligning the center of the wheel with the arbor hole of the back plate, and
aligning the drive pin hole (D) of the wheel with the drive pin of the back plate.
4. Replace the lock button with the three screws. Tighten the three screw
evenly, in rotation, and firmly enough to pinch the cork gasket.. Close the
door of the model trimmer, and secure it with the Door Secure Knob (A). Your
Foster model trimmer is now ready to operate. CAUTION: NEVER
OPERATE OR TURN ON THE MODEL TRIMMER WITH THE DOOR OPEN.
