screw back into the mandrel to secure the cutting/sanding disc in position for use (do not
over-tighten)
Attaching the flexible shaft
Note: The 3.2mm Collet (2) will need to remain in the tool in order to secure the Flexible Shaft's

Operation
WARNING: ALWAYS wear eye protection, adequate respiratory and hearing protection, as
well as suitable gloves, when working with this tool.
Switching on and off
1. Start the hobby tool by moving the On/Off Switch (8) to the 'I' position
2. Stop the tool by moving the switch to the '0' position
Adjusting tool speed
WARNING: ALWAYS set the speed according to the requirements of the accessory fitted and
the material of the workpiece.
• Use the Variable Speed Dial (6) to control the rotation speed
Note: The higher the number on the dial the faster the spindle rotates.
Handling
WARNING: Always ensure the workpiece is adequately secured using clamps and/or a vice at all
times. Do not attempt to use this tool without sufficiently securing the workpiece first.
• Hold the tool securely, keeping hands well away from rotating parts. For most purposes, it is
most convenient to grip the tool as though it is a pen
• If possible hold the tool with both hands when performing cutting operations
• Practice using the tool with scrap material before starting a job. Be aware that different
accessories will require different techniques, and may require different speed settings
• Applying excess pressure does not result in faster or more efficient performance. If the
pressure applied to the tool has a noticeable effect on the speed of the tool then reduce the
pressure. Overloading the tool will reduce its service life
• Always ensure that material is secure. If appropriate use a vice or clamp to hold the work
Accessories
• A range of accessories and consumables, including Rotary Tool Accessory Kit 216pce, Rotary
Tool Telescopic Hanging Stand, and Panoramic Safety Goggles, is available from your GMC
stockist. Spare parts can be obtained from toolsparesonline.com

carried out by an authorised GMC service centre. This advice also applies to extension cords
used with this tool
Cleaning
WARNING: ALWAYS wear protective equipment including eye protection and gloves when
cleaning this tool.
• Keep your tool clean at all times. Dirt and dust will cause internal parts to wear quickly, and
