Insert the cutter shank into the collet at least
all the way to the marked line indicated on the
shank. This ensures at least 3/4 of the shank
is held in the collet.
The cutter can be used freehand in any
portable router which has the capacity to
take a 1/2” (12.7mm) shank. If the cutter is
to be used in a workshop environment then

in a table. To use the router in a stationary
position would necessitate machining any
stiles or rails before the final assembly of the
door or frame.

Safety Points
1. Disconnect power tool and attachment from power supply when not in
use, before servicing, when making adjustments and when changing
accessories such as cutters. Ensure switch is in “off” position and cutter
has stopped rotating.
2. Read and understand instructions supplied with power tool, attachment
and cutter.
3. Current Personal Protective Equipment (PPE) for eye, ear and
respiratory protection must be worn. Keep hands, hair and clothes
clear of the cutter.
4. Before each use check cutter is sharp and free from damage. Do not
use if cutter is dull, broken or cracked or if any damage is noticeable or
suspected.
5. The maximum speed (nmax) marked on tool or in instructions or on
packaging shall not be exceeded. Where stated, the speed range
should be adhered to.
6. Insert the shank into the router collet at least all the way to the marked
line indicated on the shank. This ensures at least 3/4 of shank length is
held in collet. Ensure clamping surfaces are clean.
7. Check all fixing and fastening nuts, bolts and screws on power tool,
attachment and cutting tools are correctly assembled, tight and to
correct torque setting before use.
8. Ensure all visors, guards and dust extraction is fitted.
9. The direction of routing must always be opposite to the cutter’s
direction of rotation.
10. Do not switch power tool on with the cutter touching the workpiece.
11. Trial cuts should be made in waste material before starting any project.
12. Repair of tools is only allowed according to tool manufacturers
instructions.
13. Do not take deep cuts in one pass, take shallow passes to reduce the
side load applied to the cutter.
