Bosch Power Tools PR20EVSNK Router User Manual


 
Installation of Bit
1. Insert bit to the desired depth as per the
instructions on page 9.
2. Press large red spindle lock button on top of
offset spindle (Fig. 27).
3. Tighten collet nut using the same collet
wrench as is used on the motor’s own collet
nut. (The collet used on the PR004 is the
same type of self-releasing collet used on
the motor itself when used with the other
bases.)
4. Make a trial cut to check the depth and
readjust as necessary.
Using the Offset Router
The principles of using the offset router are
basically the same as for the fixed-base router
set-up (motor in fixed-base assembly), with the
following differences
1. The offset router should be gripped with one
hand gripping the motor gripping area and
the other hand gripping the back of the base
housing (Fig. 23) or gripping the top of the
offset spindle.
2. For routing backsplashes and other elevated
workpieces, some installers mount the offset
base to a wood block that matches the
height of the laminated backsplash. This
helps to maintain a consistent angle
between the bit’s cutter and the workpiece
and to provide addition stability.
Offset Base Roller/Bushing Guide
The PR004’s roller/bushing guide is required
when edge-forming or trimming with unpiloted
non-bearing bits.
Attachment of Roller/Bushing Guide
The PR004’s roller/bushing guide is attached
using two screws with a Philips screwdriver
(not included). Fig. 28
Adjustment of Roller/Bushing Guide
Whether making straight or bevel cuts, the
width of material removed is determined by the
distance between the front of the router bit’s
cutter and the front of the roller/bushing. Adjust
the front of the roller/bushing as follows
(Fig. 29):
1. Using a Phillips screwdriver, to adjust,
loosen screw.
2. Rotate the knurled knob on back of the
guide to move the roller/bushing in or out to
create amount of cutter exposure needed to
trim the laminate flush with the guiding
surface or to create the desired bevel.
3. Be sure the bit clears the top of the
roller/bushing guide by at least 1/8" (3 mm)
to avoid damage.
4. Tighten clamping screw using a Phillips
screwdriver.
5. Make a trial cut to check the setting and
readjust as necessary.
Use of the PR004 with
Roller/Bushing Guide
1. With the guide installed and adjusted, the
router should be fed normally, keeping the
guide in contact with the edge of the
workpiece at all times.
2. To maintain a consistent width of cut, a
consistent angle must be maintained
between the router and the workpiece.
