ENERAL POWER TOOL SAFETY WARNINGS

WARNING
Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below 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 mains operated (corded) power tool or battery-operated (cordless) power tool.

WORK AREA SAFETY

• Keep work area clean and well lit. Cluttered or dark areas invite accidents.
• 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.
• Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

ELECTRICAL SAFETY

• 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.

• 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.

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

• 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.

• 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.

• 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

• 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
• Use personal protective equipment. Always wear eye protection. Protective equipment such as a dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce
• 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.
• 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
• Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
• Dress properly. Do not wear loose clothing or jewellery. Keep your hair and clothing away from moving parts. be caught in moving parts.
• 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.
• Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause

POWER TOOL USE AND CARE

• Do not force the power tool. Use the correct power tool for your application. The correct power tool will designed.
• 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.
• Disconnect the plug from the power source and/or remove the battery pack, if detachable, 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.
• 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.
• Maintain power tools and accessories. 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.
• Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
• 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.
• Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

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.

GRINDER SANDER SAFETY WARNINGS

• Always wear safety googles and a dust mask.

• Wear ear protectors. Exposure to noise can cause hearing loss.

• The product is not suitable for wet grinding and sanding.

• Do not use a damaged accessory. Before each use, inspect the accessory such as abrasive wheels for chips and cracks. After inspecting and installing an accessory, position yourself and bystanders away from the plane of the rotating accessory and run the power tool at maximum no-load speed for one minute. Damaged accessories will normally break apart during this test time.

• The rated speed of the accessory must be at least equal to the maximum speed marked on the power tool. Accessories running faster than their rated speed can break and fly apart.

• Never grind on the sides of a grinding wheel. Grinding on the side can cause the wheel to break and fly apart.

• The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances. If you are not sure, have a certified electrician check the receptacle.

• Mount the grinder sander firmly to the workbench, grinding stand or other rigid frame before operation. An unsecured grinder sander is unstable and may move

• Provide adequate general or localized lighting to prevent stroboscopic effect and hazards.

• Always use the product with grinding wheel and sanding belt fitted on both spindles in order to limit the risk of contact with the rotating spindles.

• Always use the guards, work rests, transparent screens and spark arrestors as required for the accessory(ies). the work rest and the tangent of the grinding wheel is aways greater than 85°.

• Prior to operation, inspect the components and any accessories of the grinder sander to ensure there are no conditions that may affect proper operation. Tighten grinding wheel lock nuts, securing bolts and all clamps and guards.

• Prior to each start up, inspect the grinding wheel for damage. Do not use damaged or misshapen wheels. Replace any damaged grinding wheel according to the instructions.

• Check that the wheel rotates freely prior to each start up. With the grinder sander unplugged and the switch turned to OFF, carefully spin the wheel by hand. The wheel should not contact any components of the bench grinder, and there should be no  binding or other conditions that may affect proper operation.

• During each start-up, stand to one side of the grinder sander and switch it ON. Let the grinder sander operate at full speed for one minute so that any undetected flaws or cracks of the wheel will become apparent. Do not contact the wheel with the work  piece until the grinder sander has reached full speed.

• Keep hands and body parts clear of grinding wheels. Contacting the rotating

• Always use guards and transparent screens. Keep all guards in place and in working order. Operating the grinder sander without guards or with damaged guards

• Avoid burns. Grinding may cause items and the grinding wheel to become hot. Do not touch the grinding wheel or items that may be hot.

• Do not use the grinder sander to work on small items or items which cannot be held properly. The item may be thrown and result in injury.

• Never grind on the side of the wheel. The wheel will shatter. Grind on the face of the wheel only.

• Never leave a running tool unattended. Turn the power switch to OFF. The grinding wheels continue to rotate after the tool is switched off. Do not leave the tool until it has come to a complete stop.

• Never reach behind or beneath the grinding wheels.

• Use ear protection, such as plugs or muffs, during extended periods of operation.

• Remove the plug before carrying out any adjustment, servicing or maintenance. The power cord must remain unplugged whenever you are maintaining your grinder sander.

• Adjust the work rests and spark arrestors frequently so as to compensate for the wear of the grinding wheel.

• Adjust tool rests whenever necessary to keep the distance between the work rests and the grinding wheels as small as possible. This distance should be less than or equal to 2 mm. As the diameter of the grinding wheel decreases with use, maintain the maximum tool rest distance by adjusting it.

• Adjust spark arrestors whenever necessary to keep the distance between the spark arrestors and the grinding wheels as small as possible. This distance should be less than or equal to 2 mm. As the diameter of the grinding wheel decreases with use, maintain the maximum spark arrestor distance by adjusting it.

• Replace the worn wheel when the distance of 2 mm between the spark arrestor/work rest and the wheel are no longer able to be maintained.

• If the spark arrestor or work rest becomes worn or damaged, replace it with an identical replacement from the authorised service centre.

• When fitting a new grinding wheel, always check that the stated maximum RPM meets or exceeds that stated on the grinder sander. Ensure the wheel diameter and arbor size meet that stated on the specifications. Also check the new wheel for damage, such as flaws or cracks.

• Do not use sanding belt larger than needed.

• Make sure the sanding belt is installed in the correct direction.

• Do not operate the product without a properly tracked and fitted belt. An incorrectly tracked belt may come off the product and cause personal injury or damage to the product.

• Change the sanding belt frequently to maintain the product’s ability to effectively remove material.

• Do not use a sanding belt which is damaged, torn, or loose. Use only a sanding belt of the correct size.

• Choose a belt of the correct size and appropriate roughness for the task. Use belts with a lower grit number for removing more material, higher grit number for removing less material and for a finer finish. Replace  the belt if it becomes damaged. clogged with debris or I is worn.

• Do not force the product. Use the correct product for your application. The correct product will do the job better and safer at the rate for which it was designed.

• Always hold the workpiece firmly when grinding or r sanding.

• To minimise the risk of tipping machine, always support long workpieces.

• Never grind or sand more than one workpiece at a time. Do not stack more than one workpiece on the work rest at a time.

• Do not reach into the product while it is running.

• Avoid awkward operations and hand positions where a sudden slip could cause your hand to move into the grinding wheel or sanding belt.

• Avoid kickback by grinding or sanding in accordance with directional arrows.

• Never stand or have any part of your body in line with the path of the workpiece.

• Chips and splinters must not be removed while the
  product is running.

• The dust produced when using the product may be r harmful to health. Do not inhale the dust. Use a dust absorption system and wear a suitable dust protection mask. Remove deposited dust thoroughly. e.g. with a vacuum cleaner.
