Manual

General Safety

WARNING Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.

WARNING: This appliance is not intended for use by persons (including children) with reduced, physical or mental capabilities or lack of experience or knowledge unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety. Children must be supervised to ensure that they do not play with the appliance.

Save all warnings and instructions for future reference.

The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

1) Work area safety

a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.

b) Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.

c) Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

2) Electrical safety

a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of

electric shock.

b) Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.

c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.

d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.

e) When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

f) If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.

3) Personal safety

a) Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.

b) Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.

c) Prevent unintentional starting. Ensure the switch is in the off position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents.

d) Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.

e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.

f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.

g) If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.

4) Power tool use and care

a) Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.

b) Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.

c) Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.

d) Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.

e) Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.

f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

g) Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.

5) Service

a) Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

Grinding Tool/Electric Chainsaw Sharpener Safety

• Always wear appropriate personal protective equipment. When using this machine, adequate eye protection, ear defenders and breathing protection must be worn

• DO NOT operate this machine without the appropriate guards in place

• Grinding tool accessories must be mounted, used and stored in compliance with the manufacturer’s recommendations

• The maximum speed of the cutting/grinding disc or other accessory must always be higher than the maximum speed of the machine on which they are mounted

• Do not use any form of spacers or adapters in an attempt to make an incorrectly sized wheel fit your machine

• Ensure that the cutting/grinding disc or accessory is fitted correctly and securely before use. Run the machine with the disc or accessory fitted, but without load, for a reasonable time before attempting to cut/grind. 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 operate the machine safely

• If the grinding wheel vibrates, turn off the machine immediately and check it is mounted correctly securely and that it is not damaged

• All wheels and accessories 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 disc is safe to operate, DO NOT USE AND DISCARD

• Always ensure that accessories are suitable to use. Check the expiry date on the label. Resin-based and other grinding and cutting discs and wheels CANNOT SAFELY BE USED beyond their expiry date

• Do not allow discs 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

• The wheel will continue to rotate for some time after the machine has been switched off. Allow the moving parts to stop completely without interference. Do not try to stop the machine by holding an object against the disc

• A grinding wheel will gradually wear down during use, reducing its size. If a wheel becomes too small to work with easily, stop using it and replace it with a new disc

Cleaning and degreasing of saw chains

• Saw chains must be thoroughly cleaned, degreased and dried prior to sharpening

WARNING: Always wear cut-proof gloves when handling saw chains.

• Clean all chain links according to the chain manufacturer’s recommendations

• Refer to the lubricant manufacturer’s instructions and recommendations for chain degreasing

Understanding saw chains

Before sharpening, familiarise yourself with the different elements of the chain. A saw chain has left and right angled cutting surfaces (‘teeth’). These take alternate chips from the wood as they make contact. A curved depth gauge is located in front of each tooth. The exact angles of the teeth and the height of the depth gauges are crucial to achieving efficient cutting.

Operation

WARNING: Always unplug the sharpener from the mains power supply before making adjustments.

WARNING: Saw chains are extremely sharp. Handle with care. Wear suitable cut-proof gloves.

WARNING: The grinding wheel supplied is suitable for sharpening chains with a 3/8" pitch only. Attempting to sharpen other types of chain with this wheel may cause permanent damage. Never attempt to sharpen objects other than saw chains with this tool.

WARNING: Ensure the chain is clean and free from oil prior to sharpening.

WARNING: Even though a quality saw chain can be sharpened multiple times, it is a consumable item. Inspect chains for wear and damage. Discard chains that show signs of damage, distortion or excessive wear. Do not use chains with links that do not move freely and easily.

Switching on and off

WARNING: Keep away from the wheel when it is turning. Ensure no other person is standing in the vicinity of the machine or in line with the wheel rotation trajectory.

Note: Do not switch the machine on/off when under load. Always allow the motor to reach its full speed before applying load, and to stop completely before leaving unattended.

Note: Always test the grinding wheel by running it for a few seconds before making contact with the saw chain.

• To start the machine, press the part of the On/Off Switch (5) marked '1'

• To stop the machine, press the part of the On/Off Switch (5) marked '0'

Sharpening a saw chain

Note: Ensure the tool is set up as described in ’Fitting the chain clamp assembly and setting the sharpening angle’ in order to begin sharpening the left angled teeth.

Sharpening the left angled teeth:

1. Place the chain into the Chain Clamp Assembly (11). The hook of the teeth should face away from you

2. Lower the Chain Stop (13) so that it is resting on the rear of a left angled tooth

3. Rotate the Chain Stop Adjustment Knob (12) so that the tooth is properly positioned when the grinding wheel is pulled down

4. Lock the chain into place by screwing the Chain Locking Knob (9) inwards

5. Check that the depth stop is correctly set. The machine head should be stopped before the wheel can cut into the lower part of the chain. To adjust, rotate the Depth Adjustment Knob (7) 6. Connect the machine to the mains supply and switch on

7. Grip the Handle (4) and pull the wheel down onto the blade tooth

WARNING: Remove as little material as possible and do not work too long on a tooth. The maximum amount that can be removed from each single tooth varies from chain to chain. Obtain this information from the chains manufacturer’s instructions and recommendations.

8. Raise the wheel and switch off. Allow the wheel to come to a complete stop, and disconnect from mains supply before proceeding

9. Loosen the Chain Locking Knob (9) and move the chain forward so that the Chain Stop (13) is resting on the rear of the next left angled tooth

10. Repeat the above steps to sharpen the rest of the left angled teeth

Sharpening the right angled teeth:

11. Loosen the Angle Locking Knob (8) (the machine might need to be removed from the workbench) and rotate the clamp assembly clockwise until the sharpening angle recommended by the chain manufacturer shows on the left side of the ‘0’ mark

12. The right angled teeth can now be sharpened in the same way as for the left

Fig. A

Adjusting the height of chain depth limiting gauges

• Once all the teeth have been sharpened, the depth gauges must be checked

• The depth gauges are measured against the teeth (see Fig. A). Refer to chain manufacturer’s literature for the correct depth setting

• If the chain has been repeatedly sharpened, the chain depth limiting gauges may need to be filed down using a flat metal file (not included) as shown in Fig. A

• File down each gauge so that they are at the distance to the cutting teeth recommended by the manufacturer
