Fixing The Clamp Lever; Changing The Stop Latches - Festool DOMINO DF 500 Instruction Manual

– For best results, only the tip of the bit
should be ground, not the sides.
– The maximum tip material removal from
sharpening before the bit must be replaced
is approximately 1mm. Any more than this
and the bit will be too short for proper fi t
of the tenons.
Cleaning and Maintenance
– Blow off the exterior of the machine with
low-pressure compressed air to remove
sawdust, but do not blow air directly into
the air cooling vents on the back of the mo-
tor as this can drive debris into the motor.
– Blow out impacted sawdust from the mor-
tising bit area.
– Do not remove the fence body from the
motor housing when the joiner is coated
with sawdust.
– With the exterior of the joiner free from
sawdust, remove the fence body from the
motor housing and clean the linear slides:
• With a soft cotton cloth, wipe down the
linear rails.
• With compressed air, blow out any dust
from inside the linear bores.
• With a soft cotton cloth, wipe down the
interior of the bronze linear bearings.
– With a clean cotton cloth (not the same
cloth used previously), apply a coating of
light-weight machine oil to the linear rails.
• Use a lightweight machine oil such as
"sewing machine" oil or pneumatic tool oil.
• Do not use a penetrating oil as these may
contain solvents and detergents that can
remove the impregnated lubricant from
the bronze bearings.
• Do not use a rust inhibiting fl uid/oil as
these have limited lubrication properties,
and can also remove the impregnated
lubricant from the bronze bearings.
– With the plunge depth set to maximum,
plunge the joiner in and out several times
to spread the lubricant into the internal
bronze bearings.
– Remove the fence body from the motor
housing and wipe off the excess oil from
the linear rails.
– Replace the fence body onto the motor
housing.
– Never store the joiner with the fence body
separated from the motor housing, as this
can permit dust and debris to enter the
linear slide.

Fixing the clamp lever

– Remove the clamp lever [21.1] as shown
in [Fig. 21] step 1 and 2.
– Clamp the hexagon bolt [21.2] more fi rmly,
as described in step 3.
– Place the clamp lever onto the hexagon bolt
and secure with the cross head screw.

Changing the stop latches

It is important that the two stop latches are
perfectly spaced from the center of the mor-
tise hole for properly aligned mortises.
If the position of the Domino tenons, which
were created with the left and the right stop
latch, does not exactly match (different dis-
tance to workpiece edge) a change of the stop
latches is necessary:
Special stop latches for making accurate
adjustments are included in the scope of
delivery.
22.1
a
Remove one of the stop latches mounted
on both sides of the dowel jointer [Fig.
22a]:
• Step 1: loosen the hexagon socket screw.
• Step 2: lift up the stop latch, pull to the
side and remove.
