Maintenance - Ryobi BT3100K Owner's Operation Manual

WARNING:
Begin by unplugging your saw. Failure to unplug saw
could result in accidental starting causing possible serious
injury.
TO ADJUST THE MITRE FENCE
■ Set the mitre fence (H) at 0° as shown in figure 53. Mitre
indicator (I) should be set precisely on 0° and secured in
place with adjusting clamp (J).
■ There are four slides located under the sliding mitre table.
These slides let the mitre table move on the base. Three
slides are mounted on eccentric screws that can be
adjusted by loosening the hex nuts on top of the mitre
table. See Figure 55.
■ Loosen the rear hex nuts (Q) on top of sliding mitre table
for this adjustment procedure.
Note: The front screws (R) are only needed to remove
excessive play in the slides due to wear from extended
use. They are not needed for this procedure. The right
front hex nut is a non-eccentric pivot and should never be
loosened.
■ Adjust the right rear eccentric screw from the lower side
of the mitre table so that maximum play exists between
the slide and mitre base.
■ Push left rear of mitre table snugly against mitre base as
shown by the arrow (S) in figure 56 and secure.
■ Place a framing square firmly against the mitre fence, with
the other side against the blade.
■ Adjust left rear screw from underneath mitre table until
mitre fence and blade are square with each other.
■ Tighten hex nut securely.
■ Adjust right rear screw from underneath mitre table to
remove excessive play.
■ Tighten hex nut securely.
■ Recheck your setups carefully. Also make sure all screws,
hex nuts, etc. have been tightened securely.
■ If sliding mitre table assembly is still not square with the
blade, repeat the above procedures as needed.
■ Make sure that slides remain square to mitre base edge
to prevent "cocking" which will result in excessive play in
mitre table.
TO ADJUST QUICK-STOP
The quick-stop is preset at the factory to stop the mitre fence
at exactly 0°. However, when sliding mitre table adjustments
are made, these adjustments may cause the quick stop to
need adjusting. Check quick-stop with mitre scale set at 0°.
If adjustments are needed, proceed with the following steps:
■ Loosen the eccentric screw holding the quick-stop.
■ Place the quick-stop against the mitre fence with mitre
scale set at 0°. See Figure 57.
■ Adjust eccentric screw until it holds quick-stop securely
against mitre fence.
■ Retighten hex nut, securing eccentric screw and quick-
stop.
■ Check your work. If the quick-stop is not at 0°, repeat
above steps.
