GENERAL SAFETY RULES FOR OPERATION
WARNING! Read all instructions. Failure to follow all instructions listed
below may result in electric shock, fire and/or serious injury. The term
“power tool” in all of the warnings listed below refers to your mains-operated
(corded) power tool or battery-operated (cordless) power tool.
SAVE THESE INSTRUCTIONS
Work Area
- a. Keep work area clean and well lit. Cluttered and 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.
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.
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 safety equipment. Always wear eye protection. Safety equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
- c. Avoid accidental starting. Ensure the switch is in the off-position before plugging in. Carrying power tools with your finger on the switch or plugging in 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.
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 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 tools 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 and in the manner intended for the particular type of power tool, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from intended could result in a hazardous situation.
Service
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.
ADDITIONAL SAFETY RULES FOR BENCH GRINDERS
- a. Ensure that the bench grinder is disconnected from the mains supply when not in use, before servicing or making adjustments and when changing accessories such as grinding wheels.
- b. Always use the correct type of grinding wheel for the type of operation to be carried out and the material being machined. Do not use a grinding wheel as a cutting disc.
- c. Only use grinding wheels that are in good condition. This will improve grinding and reduce the load on the machine ensuring a longer life of the grinding wheel and the machine.
- d. Never use damaged grinding wheels. Grinding wheels that are cracked, chipped or worn could shatter causing injury to the operator and bystanders and damage to the machine.
- e. Do not use grinding wheels that are larger than specified, only use grinding wheels that are rated for the machine. The rotational speed shown on the grinding wheel should always be HIGHER than the rotational speed of the machine.
- f. Always fit the blotter or paper washers on either side of the grinding wheel if not already fitted to the grinding wheel.
- g. When fitting a new wheel ensure blotter or paper washers are in place, fit concave side of washers to face the wheel and tighten the lock nut firmly.
- h. Do not over tighten (over tightening can crack a grinding wheel).
- i. Do not attempt to modify the machine or its accessories in any way.
- j. Do not use excessive force on the grinding wheel. Only use gradual pressure as this will reduce the wear on the bench grinder and grinding wheels and increase its efficiency and operating life.
- k. Use approved safety glasses or goggles, face mask and if being used for an extended period wear ear defenders.
- l. Do not start the machine with the work piece in contact with the grinding wheel or before checking the position of the tool rest.
- m. Never apply the work piece to the side of the grinding wheel, this could cause the grinding wheel to shatter.
- n. Keep guards in place and in good working order. With the machine disconnected from the mains supply check that the guards are secure and fitted correctly.
- o. Always keep the tool rest as close to the grinding wheel as possible. The gap between the tool rest and the grinding wheel should be no more than 3mm.
- p. Do not attempt to grind objects that are too small to hold safely.
- q. Do not use the work piece to slow down the grinding wheel once the machine has been switched off.
- r. WARNING! Do not use bench grinders in areas where there is a risk of explosion or fire from combustible materials, flammable liquids, paint, varnish, petrol etc. flammable gases and dust of an explosive nature. As a precaution it is recommended that you consult an expert on a suitable fire extinguisher and its use. The metal particles (sparks) which are produced during grinding are hot and could ignite any combustible material in the vicinity of the operation.
WARNING Ensure the bench grinder is disconnected from the power supply when performing maintenance tasks to avoid injury.
MAINTENANCE REQUIRED FREQUENCY

WHEEL DRESSING
Wheel dressing is done to renew sharpness or to true up the face of a wheel. A
build up of metals and dirt will become embedded in a wheel as it is used. Use
a wheel dressing tool (not supplied) to clean wheels on a regular basis. In
doing so, it will improve the bench grinder’s performance.
NOTE: New wheels may sometimes require dressing to true up their surface.
CLEANING
Use only mild soap and a damp cloth to clean the bench grinder. Never let any liquid get inside the tool. DO NOT immerse any part of the bench grinder into a liquid. Service beyond recommended maintenance on this bench grinder should only be performed by an authorized, qualified technician.
GETTING STARTED
Accessories
- The bench grinder is supplied with the following accessories:
- 2 eye shields with mounting brackets and 2 tool rests
- CAUTION. Always ensure that the bench grinder is switched off and plug is removed from the power point before making any adjustments.
- To fit the eye shields locate the nut, screw and washers provided through the slot in the eye shield and hole on the grinding wheel guard and finger tighten. Position the eye shield so it does not come in to contact with the grinding wheel. Tighten the nut and screw to secure the eye shield in place.
- Attach the tool rests using the bolts and securing knobs provided and adjust to the correct position. The gap between the tool rest and grinding wheel should be set to 2mm.
Bench Mounting
The Grinder can be secured with screws or nuts and bolts. Locate the mounting
holes. The length of the bolts or screws will depend on the thickness of the
bench. Where a steel bench is used, it is best to mount the grinder on to a
board, then attach the board to the bench, this will also minimize vibration.
Switching On And Off
Before connecting to the power supply rotate the wheel by hand to ensure that
it is running properly and free from obstruction. Connect to the mains supply
and press the rocker switch to the ON position (l).To stop the machine simply
press the rocker switch to the OFF position (o).
General Inspection
Regularly check that all the fixing screws are tight. They may vibrate loose
over time.
