to your trim router motor and cutter). A deep cut requires
a slower feed than a shallow cut and a too deep cut will
cause you to slow the feed so much that the cutter is no
longer cutting.
Making a deep cut is never advisable. The smaller cutters
especially those only 1.6 mm in diameter are easily broken
when subjected to too much side thrust. A large cutter
may not break, but if the cut is too deep a rough cut will
result and it may be very diffi cult to guide and control the
cutter as desired. For these reasons, we recommend that
you do not exceed 3 mm depth of cut in a single pass,
regardless of the cutter size or the softness or condition
of the workpiece. This will result in a higher quality cut.
To make deeper cuts it is therefore necessary to make as
many successive passes as required, lowering the cutter
3 mm for each new pass. In order to save time, do all the
cutting necessary at one depth setting, before lowering the
cutter for the next pass. This will also ensure a uniform
depth when the fi nal pass is completed.
WARNING
If desired depth of cut is greater than it can be safely cut
in one pass, make cuts in two or more passes.
DIRECTION OF FEED AND THRUST
See fi gure 12
The trim router motor and cutter revolve in a clockwise
direction. This gives the tool a slight tendency to twist (in
your hands) in a counterclockwise direction, especially
when the motor starts.
Because of the extremely high speed of cutter rotation
during “proper feeding” operation, there is very little
kickback under normal conditions. However, should the
cutter strike a knot, hard grain, foreign object etc, that
would affect the normal progress of the cutting action,
there will be a slight kickback — suffi cient to spoil the
trueness of your cut if you are not prepared. Such a
kickback is always in the direction opposite to the direction
of cutter rotation.
To guard against such kickback, plan your setup and
direction of feed so that you will always be thrusting the
tool to hold it against whatever you are using to guide the
cut in the same direction that the leading edge of the cutter
is moving. In short, the thrust should be in a direction that
keeps the sharp edges of the cutter continuously biting
straight into new (uncut) timber.
MAINTENANCE
WARNING
When servicing use only identical replacement parts.
Use of any other parts may create a hazard or cause
product damage.
BRUSH REPLACEMENT
See fi gure 13
Your trim router has externally accessible brush
assemblies that should periodically be checked for wear.
Proceed as follows when replacement is required:
Unplug your trim router.
WARNING
Failure to unplug your trim router could result in
accidental starting causing serious injury.
Remove the brush cap with a flat blade screwdriver.
Brush assembly is spring loaded and will pop out when
you remove the brush cap.
Remove the brush assembly (brush and spring).
Check for wear. If worn, always replace in pairs. Do
not replace one side without replacing the other.
Reassemble using new brush assemblies. Make sure
curvature of brush matches curvature of motor and
that the brush moves freely in the brush tube.
Make sure the brush cap is oriented correctly (straight)
and replace.
Tighten the brush cap securely. Do not over tighten.
PROPER CARE OF CUTTERS
Get faster, 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 outer diameter. Be sure when sharpening the
end of a cutter to grind the clearance angle the same as
originally ground.
PROPER CARE OF COLLET
From time to time, it also becomes necessary to clean
your collet and collet nut. To do so, simply remove collet
nut from the collet and clean the dust and chips that have
collected. Then return the collet nut to its original position.
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.
If the power supply cord is damaged, it must be replaced
only by the manufacturer or by an authorized service
