Adjustments - RIDGID R4512 Operator's Manual

ADJUSTMENTS

WARNING:
Before performing any adjustment, make sure
the tool is unplugged from the power supply and
the switch is in the OFF ( O ) position. Failure to
heed this warning could result in serious personal
injury.
To avoid unnecessary set-ups and adjustments, a good
practice is to check your setups carefully with a framing
square and make practice cuts in scrap wood before making
finish cuts in good workpieces. Do not start any adjustments
until you have checked with a square and made test cuts to
be sure adjustments are needed.

tightened. Do not overtighten.
