Drill Bit Sharpener Safety
WARNING: Bench mounted and other non-handheld power tools limit
user exposure to vibration but it is still important to be aware of
vibration levels and stop operating the tool if the vibration level causes
discomfort. Take regular breaks when operating the tool.
• ALWAYS wear appropriate personal protective equipment including eye
protection, ear defenders and respiratory protection
• Grinding tools and accessories must be mounted, used and stored in
compliance with the manufacturer's recommendations
• Use ONLY compatible replacement grinding wheels as stated in
this instruction manual. Attempting to use any other accessory or
attachment is extremely dangerous and could lead to serious injury or
destruction of the device
• DO NOT use any form of spacers or adapters in an attempt to make an
incorrectly sized grinding wheel fit your machine
• Ensure that the grinding wheel is fitted correctly and securely before
use. Run the machine with the grinding wheel fitted, but without
load, for a reasonable time before attempting to sharpen drill bits. If
excessive vibration occurs, stop the machine, investigate and correct
the cause before use. Seek professional guidance if you are in doubt
about how to set up or operate the machine safely
• All replacement grinding wheels must be checked before installation.
If a wheel is damaged in any way, such as by being chipped, fractured,
warped or misshapen, DO NOT USE AND DISCARD. If you are unsure
about whether a grinding wheel is safe to operate, DO NOT USE AND
DISCARD
• Always ensure that grinding wheels are suitable to use. Check the
expiry date on the label. Grinding wheels CANNOT SAFELY BE USED
beyond their expiry date
• DO NOT allow grinding wheels to become wet or contaminated with
oil. If you suspect that a wheel has degraded in storage, or if you are
unsure about whether its expiry date has passed, DO NOT USE AND
DISCARD

Unpacking Your Tool
• Carefully unpack and inspect your new tool. Familiarise yourself with all
its features and functions
• Ensure that all parts of the tool are present and in good condition. If
any parts are missing or damaged, have such parts replaced before
attempting to use this tool
Before Use
WARNING: Ensure the tool is disconnected from the power supply
before attaching or changing any accessories, or making any
adjustments.
WARNING: ALWAYS handle drill bits with care and avoid touching the
cutting edges. Burrs and sharp edges may cause deep skin cuts. Drill bits
become hot during sharpening, and can cause severe burns.
WARNING: This tool is suitable for sharpening twist drill bits ONLY. Masonry,
lip and spur, auger, flat and step drill bits and router cutters can NOT be
sharpened with this device.
• Place the sharpener on a sturdy, even surface and connect the plug to
the power supply
• Clean drill bits prior to sharpening, to remove dirt, grease and cutting
fluids. Drill bits must be completely dry
Adjusting the grinding wheel
Note: Depending on the drill bit you may need to adjust the height of the
Grinding Wheel (8).
1. Turn the Adjustment Knob (5) clockwise to raise the Grinding Wheel
• Raising the Grinding Wheel will lead to a more aggressive cutting action
• When sharpening short drill bits, it may be necessary to raise the
grinding wheel
2. Turn the Adjustment Knob anticlockwise to lower the Grinding Wheel
• Lowering the Grinding Wheel will lead to a finer ground edge
• Fine grinding may take longer and can require additional repetitions
• When sharpening long drill bits, it may be necessary to lower the
Grinding Wheel
Operation
WARNING: ALWAYS wear eye protection, adequate respiratory and
hearing protection, as well as suitable gloves, when working with this
