6 Service and Maintenance
6.1 Tool Changes
Caution: Do not attempt to change tooling with compressed air power supplied to the
machine!
You do not need to remove the Work Top to change the bits, but removal of the Work Top will
give access to the Router Motor and facilitate the removal of the Trimmer Motor. To change the
Pocket Router Bit or the Pilot Drill Bit without removal of the Work Top, you will need to remove
the respective motors from the carriage.
6.2 Pocket Router Bit
• Open the rear door and unplug the router motor.
• Locate the black T-Knob to the right of the drill motor at the top of the carriage. The black T-
Knob is threaded onto a large U-bolt that secures the Router Motor.
• Support the bottom of the Router Motor with your left hand (Fig 21). Use your right hand to
loosen the T-Knob a few turns to provide slack on the U-bolt. (Push slightly forward on the
T-knob if necessary.)
