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
GB 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
See Image M
The Turret Stop (13) allows 6 different plunge depths to be configured for fast switching during use. 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 appropriate personal protective equipment, including eye protection 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 & 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 tool 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 finish, and
prolong the service life of your router bits.
Note: ALWAYS set the tool speed to its lowest setting before ceasing operation, as the router will resume
operation with the last speed setting used.
Base Plate
• The router features a combined flat-sided and round Base Plate (14). This allows the round edge to follow
contours easily but also gives an easy straight edge which may be useful for some straight cuts (when the
Parallel Guide (30) cannot be used), using with guide bushes and also where the edge of the Base Plate
needs to be closer to the router bit cutter, e.g. for use with dovetail jigs etc.
• Always remember which edge of the base plate you are working with as the distance is different to the
router bit cutter
If the router bit cutter impacts hard material such as metal the router bit will be destroyed and the router itself
may be damaged
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. IV), Parallel Guide (Fig. I), Circle Guide (Fig. II), roller guide (Fig. III) or
a straight edge (Fig. V).
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.
Accessories
• A full range of accessories, including router bits is available from your GMC stockist
• Spare parts can be obtained from toolsparesonline.com
Maintenance
WARNING: ALWAYS disconnect from the power supply before carrying out any inspection, maintenance
or cleaning.
General inspection
• Regularly check that all the fixing screws are tight
• Inspect the supply cord of the tool, prior to each use, for damage or wear. Repairs should be carried out by
an authorised GMC service centre. This advice also applies to extension cords used with this tool
Cleaning
• Keep your tool clean at all times. Dirt and dust will cause internal parts to wear quickly, and shorten the
machine's service life. Clean the body of your machine with a soft brush, or dry cloth. If available, use
clean, dry, compressed air to blow through the ventilation holes
• Clean the tool casing with a soft damp cloth using a mild detergent. Do not use alcohol, petrol or strong
cleaning agents
• Never use caustic agents to clean plastic parts
Lubrication
• All the bearings in this tool are lubricated with a sufficient amount of high-grade lubricant for the life of the
unit under normal conditions. Therefore, no further lubrication is required.
