(1615EVS) RA1001
Fine Adjustment Accessory
Installation and Operating Instructions
The RA1001 fine-adjustment accessory will
allow precise bit height adjustments on Bosch
routers. It is important to note that this acces-
sory restricts the movement of the router motor
on the plunge base and effectively replaces the
normal plunge action with a threaded feed.
CAUTION; Always disconnect the tool from
the power source before installing bits, acces-
sories, or making any adjustments. Never ad-
just this accessory when the tool is running or
the bit is in contact with the workpiece.
Installation
1. Plunge router down so that boss O on the
motor is not in contact with nuts J on threaded
guide rod I. Remove the 17mm locknut and two
flat nuts J from rod I with a suitable wrench
(Fig. 1).
Place washer K over
threaded rod, and re-
install one of the flat
nuts J about 3/8" from
the top of rod I. A
light film of general
purpose grease may
be applied to washer
K to help reduce fric-
tion (Fig. 2).
2. Place the threaded end of the RA1001 over
the top of rod I and press it down to compress
the spring until the cutaway portion engages nut
J and thread adjuster onto rod. When the
RA1001 is properly installed, the 17mm nut J
will protrude slightly from the cutaway end of
the RA1001 so that the face of the nut (NOT the
RA1001) will contact washer K. Figure 3
shows the RA1001 properly installed. If de-
sired, 17mm nut J below boss O may be used to
lock the router in a fixed depth setting by
tightening it against the opposite side of boss O.
(Note: Keep the nuts you have removed in a
safe place so that they may be reinstalled on
your router if the RA1001 is removed for any
reason.)
Operation
To use the RA1001, depress the plunge release
lever and turn the RA1001 clockwise to lower,
or counterclockwise to raise the bit. (Note that
one full turn of the knob will raise or lower the
bit approximately .060", or 1.5mm.) It is nec-
essary to exert slight downward pressure on the
router handle opposite the RA1001, to avoid
cocking the motor on the posts (Fig. 4).
