DEPTH OF CUT
As previously mentioned, the depth of cut (30) is important
because it affects the rate of feed that, in turn, affects the
quality of the cut (and also, the possibility of damage to
your router motor and bit). A deep cut requires a slower
feed than a shallow one, and a too deep cut will cause
you to slow the feed so much that the bit is no longer
cutting, it is scraping, instead.
Making a deep cut is never advisable. The smaller bits
— are easily broken off when subjected to too much side
thrust. A large enough bit may not be broken, but if the
WARNING:
When servicing use only identical Ryobi replace-
ment parts. Use of any other parts may create a
hazard or cause product damage.
GENERAL
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use.
Use clean cloths to remove dirt, carbon dust etc.
WARNING:
Do not at any time let brake fluids, petrol, petroleum
- based products, penetrating oils etc. come in
contact with plastic parts. They contain chemicals
that can damage, weaken or destroy plastic.
Electric tools used on fiberglass material, wallboard,
spackling compounds or plaster are subject to
acelerated wear and possible premature failure, as the
fiberglass chips and grindings are highly abrasive to
bearings, brushes, commutators etc. Consequently, we
do not recommended that this tool be used for extended
work on these types of materials. If, however, you do
work with any of these materials, it is extremely impor-
tant that you clean the tool frequently by blowing it with
an air jet.
WARNING:
Always wear safety goggles or safety glasses
with side shields during power tool operation or
when blowing dust. If operation is dusty, also
wear a dust mask.
ADJUSTMENTS
cut is too deep a rough cut will result — and it may be very
difficult to guide and control the bit as desired. For these
reasons, we recommend that you do not exceed 3.2 mm
depth of cut in a single pass, regardless of the bit size or
the softness or condition of the workpiece. To make deeper
cuts it is therefore necessary to make as many successive
passes as required, lowering the bit 3.2mm for each new
pass. In order to save time, do all the cutting necessary
at one depth setting, before lowering the bit for the next
pass. This will also assure a uniform depth when the final
pass is completed.

MAINTENANCE

LUBRICATION
All of the bearings in this tool are lubricated with a sufficient
amount of high grade lubricant for the life of the unit under
normal operating conditions. Therefore, no further lubrication
is required.
CUTTERS
Get faster and more accurate cutting results by keeping
cutters clean and sharp. Remove all accumulated pitch
and gum from cutters after each use.
When sharpening cutters, sharpen only the inside of the
cutting edge. Never grind the outside diameter. Be sure
when sharpening the end of a cutter to grind the
clearance angle the same as originally ground.
COLLET
Dust and chips may collect on the collet from time to time,
making it necessary to clean the collet. To do so, remove
the collet assembly and wipe it with a clean dry cloth.
Clean the taper in the shaft in the same manner. Never
immerse the collet or end of the shaft in a solvent or in
water. Before replacing the collet assembly, put a drop
of motor oil on the inside of the nut, on the threads of the
shaft and on the taper in the shaft. Replace the collet
assembly onto the shaft by hand only. Never tighten the
collet nut without a bit in the collet. This action could
permanently damage the collet.
