Note: Alternatively, just the Guide Block with Roller Guide attached can be connected using
two Guide Rods only. This is a lighter configuration which will eliminate the option for fine
adjustment using the Guide Micro-Adjuster Knob (Image. K)
Note: Ensure the Roller Guide wheel is kept clean and rotates freely. Lubricate with a suitable
PTFE spray if necessary.
Using the guide bush plate
A Guide Bush can be used when template/jig cutting. A 30mm Guide Bush Plate is provided
(30mm is commonly used for kitchen jigs).
A template or jig can be clamped on top of a workpiece so that the router can create exact size
shapes, patterns or writing in a workpiece surface, such as signs (Fig.V). It can also create
holes for devices that are mounted in wood such as basins, taps etc.
• Fit the Guide Bush Plate (43) into the recess in the Base Plate (14) of the router with the
raised circular edge facing away from the router and secure with the Guide Bush Screws
(44) (Image. F)
Note: Ensure the central opening diameter of the guide bush is correct for the required router
cutter fitted to the tool.
Note: Always refit the Guide Bush Screws after removing the Guide Bush Plate to secure the
dust extraction assembly.
Adjusting the plunge depth
1. Hold the router securely with two hands and press down on the Plunge Lock Lever (19)
and in a controlled manner allow the router to reset to its full height. The Plunge Lock Lever
self-locks the plunge height when released so ensure you don't release the lever until the
router is at its full height
2. Set the Turret Stop (13) to the lowest step position under the Depth Stop (12). The Depth
Stop has a major adjustment by slackening the Depth Stop Lock (11) and adjusting the
height with the Depth Stop Height Adjuster (10). Use the Depth Scale (7) and Depth Stop
Height Indicator (8) to aid adjustment of the cutter height. Ideally configure so '0' on the
Depth Scale represents the cutter height level at zero at the base plate
3. Minor adjustment of the Depth Stop can be achieved with the Depth Stop Micro Adjustment
(6). The graduations are marked in 0.1mm graduations but are only approximate
4. Retighten the Depth Stop Lock at the correct height for the required cut so when plunged
the correct depth of the router bit cutter is exposed to the material
Note: The scales and indicators can be used to check changes in depth setting, but actual
cutting depth is best measured by making a trial cut on scrap material.
Using the turret stop
The Turret Stop (13) allows 6 different plunge depths to be configured for fast switching during
use. This can massively speed up operations or allow a multi-step procedure to reaching the
final required depth of cut. This is especially important where the workpiece is more difficult to
cut, i.e. harder wood or when a better finish is required in some situations.
• Simply rotate the turret stop to the required height. For multi-step cut rotate to the highest
required position and perform the cut. Then rotate the turret to the next lowest position you
require and continue making deeper cuts until you reach the required depth
Setting the depth of cut
• To lock the router at a set depth of cut without using plunge in use, set the plunge depth as
described in 'Adjusting the plunge depth'
• Press the Plunge Lock Lever (19) down and plunge the router head down to the set Depth
Stop position
• Release the Plunge Lock Lever then check it has self-locked with the Depth Stop contacting
the Turret Stop
IMPORTANT: It is more dangerous to start the router with the cutter already exposed below the
base and requires extra care in use.
Operation
WARNING: ALWAYS wear eye protection, adequate respiratory and hearing protection,
as well as suitable non-fabric gloves, when working with this tool.
IMPORTANT: Ensure the Motor Vents (1) and other vents of the tool are kept clean. The tool
is designed with the Motor Vents at the maximum height but wood dust, chippings, metallic
swarf, fibre glass, plaster and other particles and dust can damage the tool if allowed to enter
the Motor Vents. Use a vacuum cleaner to ensure the vents are clean. If necessary blow out
with compressed air.
Switching on and off
1. Ensure that the router bit is held securely in the collet, and that the router bit cutter is not in
contact with the workpiece or any other object
2. Start the motor, hold the Safety Button (16) down, and by squeezing the On/Off Switch (26).
The router is equipped with a soft start feature so the motor will take a few moments to
reach its full operating speed
3. Stop the motor by releasing the On/Off Switch
Speed control
The speed of the router is set electronically with a range of 18 speeds from 9,000 to
27,000rpm: a higher number corresponds to a higher motor speed. 9 represents 9,000rpm and
27 represents 27,000rpm with each number in-between representing an increment of 1,000rpm
The router features 'constant speed under load', an electronic circuit that works to maintain the
set speed under load, improving cutting results and performance.
IMPORTANT: Never exceed the maximum speed of the router bit. This router has been
designed so a precise speed can be selected with no rotary wheel that can be accidentally
altered.
1. Switch on the router
2. Adjust the speed up or down with the Speed Adjustment Buttons (3)
3. The speed will be visible in the LCD Speed Display (2)
Note: Choosing the correct speed for the router bit and material will produce a higher quality
of finish, and prolong the service life of your router bits.
Note: The router remembers the last speed set so remember to set to the lowest speed at the
end of the work session so the router doesn't power up at too high a speed.
Making a cut
Note: NEVER operate the router freehand without some form of guide. Guidance can be
provided by a bearing guided router bit cutter, guide bush (Fig. V), parallel guide (Fig. I), circle
guide (Fig. III), roller guide (Fig. II) or a straight edge (Fig. IV).
1. ALWAYS hold the router using both hands, on the handles provided. Ensure the workpiece
does not move. Use clamps wherever possible
2. Allow the motor to reach the full operating speed to which it has been set
3. Lower the router bit cutter into the workpiece whilst moving the router slowly, keeping the
base plate held flat against the workpiece
4. If edge cutting, the cutting of the workpiece should be on the left side relative to the cutting
direction (Fig. VI). Maintain constant pressure and allow the cutter to work steadily through
the material. Be aware that knots and other variations will slow the rate of progress
Note: To avoid 'bit chatter', direct the cut anti-clockwise for external cuts, and clockwise for
internal cuts.
Note: Moving the router too fast can result in a poor quality finish and overloading of the motor.
Moving the router too slowly can result in overheating the workpiece.
Note: Normal operation of a router is to plunge the head after the router has been switched on.
