GENERAL POWER TOOL SAFETY WARNINGS

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. Save all warnings and instructions for future reference. The term “power tool” in the warnings refers to your electric (corded) power tool or battery-operated (cordless) power tool.

Work area safety

1. Keep work area clean and well lit. Cluttered or dark areas invite accidents.
2. Do no t operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks that may ignite dust or fumes.
3. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

Electrical safety

1. Powe r tool plugs must match the outlet. Never m odify the plug in any way. Do not use any adapter plugs with grounded power tools. Unmodified plugs and matching outlets will reduce ris k of electric shock.
2.  Avoi d body contact with grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric s shock if your body is grounded.
3. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
4. 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.
5. 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.
6. 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.

Personal safety

1. 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.
2. 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.
3. 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.
4. 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.
5. Do not overreach. Keep proper footing and balance at all times. This enables better control of the po wer tool in unexpected situations.
6. 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.
7. If devi ces are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust colle ction can reduce dust-related hazards.

Power tool use and care

1. Do not force the power tool. Use the correct power to ol for your application. The correct power tool will do the job better and safer at the rate for w hich it was designed.
2. Do no t use the power tool if the switch does not turn i t on and off. Any power tool that cannot be controlled with the switch is dangero us and must be repaired.
3. Disco nnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessori es, or storing power tools. Such preventiv e safety measures reduce the risk of starting the power tool accidentally.
4. 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 dangero us in the hands of untrained users.
5. 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.
6. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
7. 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.

Service

1. 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.
2. If the replacement of the supply cord is necessary, this has to be done by the manufacturer or its agent in order to avoid a safety hazard.

Additional Warnings for Bench Grinder

1. Firmly bolt the grinder to a work bench or leg stand at approximately hip height.

2. Never reach to pick up a workpiece, a piece of scrap, or anything else that is in or near the grinding path of the wheel.

3. Avoid awkward operations and hand positions where a sudden slip could cause your hand to move into the wheel. Always make sure you have good balance.

4. Never stand or have any part of your body in line with the path of the wheel.

5. Do not turn the motor switch on and off rapidly. This could cause the wheel to loosen and coul d create a hazard. Should this ever occur, sta nd clear and allow the wheel to come to a complete stop. Disconnect your grinder
   from the power supply and securely retighten the whee l nut.

6. Use on ly flanges furnished with this bench grinder.

7. If any part of this grinder is missing or should break, be nd, or fail in anyway, or should any electrical c omponent fail to perform properly, shut off the power switch, remove the machine plug from the power source and have amaged, missing, o r failed parts replaced before resuming operation.

8. Do not overtighten the wheel nut. Excessive tightening can cause the wheel to crack during operatio n.

9. Always use the grinder’s wheel guards and safety shields.

10. Inspect grinding wheel for visible defects. Check the wheel for fissures and cracks, and test for normal operation prior to use. Replace cracked wheel immediately.

11. Adjust the distance between wheel and work rest to maintain 1/16″. or less separation as the diameter of the wheel decreases with use. The value of separation used in the marking is to be the separation recommended by the manufacturer but shall not be more than 1/8″.

12. Always ease the workpiece against the abrasive wheel when starting to grind. A harsh impact can break the wheel. Use light pressure when starting to grind; too much pressure on a cold wheel can cause the wheel to crack.

13. Never start the grinder when the wheel is in contact with the workpiece.

14. Secure work. Always hold the workpiece firmly against the work rest.

15. Do not use the bench grinder if the flange nut or clamp nut is missing or if the spindle shaft is bent.

16. Frequently clean grinding dust from beneath the grinder.

17. Secure long hair so it is above shoulder level to prevent entanglement in any rotating parts.

18. Stay alert and exercise control. Watch what you are doing and use common sense. do not operate tool when you are tired. do not rush.

19. Do no t touch the cut material until it cools.

20. If the power supply cord is damaged, it must be replac ed only by the manufacturer or by an authorise d service centre to avoid risk.

21. Make sure the grinder is securely mounted as described in the assembly instructions before connecting the tool to a power supply.

22. Save these instructions. Refer to them frequently and use to instruct other users. If you loan someone this tool, loan them these instructions also.

Using an Extension Cable.

1. If an extension cable is required, use an approved triple core extension cable suitable for the power input of the tool.
2. Grounded tools always require a three wire extension cable.
3. As the distance from the supply outlet increases you must use a heavier gauge extension cable. Using extension cables with inadequately sized wire causes a serious drop in voltage, resulting in loss of power and possible tool damage.
4. The smaller the gauge number of the wire the greater the capacity of the cord.
5. When using a cable reel, always unwind the cable completely.

OPERATING INSTRUCTIONS

1. WARNING! KEEP TOOLS AND EQUIPMENT OUT OF THE REACH OF YOUNG CHILDREN
2. CONNECT THE WET & DRY GRINDER TO THE MAINS SUPPLY.
3. ALWAYS WEAR EAR DEFENDERS AND SAFETY GOGGLES.]

Carry out final checks e.g. check the gap between the tool rest and the stone is correct, check the stones are not badly deformed (rounded edges, grooved face, etc; unless you have specifically shaped the stone to these profiles), check the eye shield is correctly positioned. Have a cooling pot to hand if you need it. Fill the water container (L) to a level about 15-20mm below the lip of the container, see fig 01

Mark the bevel with a marker to allow you to see where the grinding will occur.

Place the tool into the jig (N) around half way along the blade and position it against the jig’s stops, see fig 3. Tighten the clamping knobs. Slide the assembly onto the universal bar (M), see fig 04.

The most common secondary bevel is 30° when the main body of the tool is ground at 25°. The chart below gives you some guidance as to which angle is most suited to which materials.

Bevel edge chisels

Primary Bevel| Secondary Bevel
20˚| Paring| N/A
25˚| 12mm-50mm| 27° – 30°
30˚| 6mm-10mm| 32° – 35°
In general, secondary bevels can be between 2° and 5°
Primary Bevel| Secondary Bevel
---|---
Mortice chisels
30˚| | No secondary bevel needed
Plane blades
25˚| | 30˚

Bevel up blades can be sharpened at different angles dependant on the grain and difficulty of the timber.

Using an angle gauge, adjust the universal support bar with the micro adjuster (M) to set the ‘Primary Bevel’ at 25˚ degrees. Make sure the heel of the bevel touches the grinding stone, see fig 06-08

. Turn the wet stone (I) by hand to check the full width of the ‘Primary Bevel’ is in contact with the stone. Make adjustments to the universal support bar until even contact.

CLEAR ALL TOOLS AWAY FROM THE WORK AREA!

Check that everything is secure, place a container under the water trough drain hose (Q). Make sure the bevel is not in contact with the wet stone and switch on the grinder. Wait until it reaches full speed. Check it runs smoothly, no knocking or scraping noises for example. Twist the regulator knob to allow water to cascade down onto the wet stone. Allow the water to cover the stone. Lower the blade so it is in contact with the revolving stone. Observe how the water flows over the width of the blade. This is very important to create an even bevel. Keep light finger pressure on the tool and slide it from left to right.

After a number of passes wipe the blade to assess the progress. A new, very bright line should appear which needs to be even across the length of the blade. If the honed edge appears one-sided simply return the guide and tool to the water stone and draw back again applying more pressure to the side with the least apparent grind. You should apply slightly more pressure to the side least ground.
The secondary bevel will work even if it is very small. It doesn’t need to be much more than 1.0mm in width for it to achieve the desired effect. When finished switch off the grinder.

Tip: Before removing the blade from the square edge jig (N), use a marker to mark the position of bevel angle as shown in fig 12. This will allow you to clamp the blade in the same position the next time it needs re sharpening.

As with all tools, this guide will need care and a fair degree of familiarisation before the user is able to get perfect results. You might want to spend time on sharpening some old tools first.
Remember, any edge is a combination of two faces. The tools, no matter how finely ground, will need to have had their reverse side flattened and honed so that it is as equally fine as the bevel edge is ground.
