Safety 

General Operational Precautions 

 

 

 

Keep work area clean. Cluttered areas and benches invite injuries. 

 

Consider work area environment. Don't expose power tools to rain. Don’t use power tools in damp or wet 
locations. Keep work area well lit. 

 

Don't use tool in presence of flammable liquids or gases. 

 

Power tools produce sparks during operation. They also produce sparks when being switched ON/OFF. 
Never use power tools in dangerous sites containing lacquer, paint, benzene, thinner, gasoline, gases, 
adhesive agents, and other materials which are combustible or explosive. 

 

Guard yourself against electric shocks. Prevent bodily contact with grounded surfaces like piles, radiators, 
ranges, refrigerator enclosures, etc. 

 

Keep children away. Do not let visitors touch the tool or extension cord. All visitors should be kept away from 
the work area. 

 

Store idle tools. When not in use, tools should be stored in a dry and high or locked-up place, out of reach of 
children. 

 

Don’t force the tool. It will do the job better and safer at the rate for which it was Intended. 

 

Use the right tool. Don't force a small tool or attachment to do the job of a heavy-duty tool. Don't use tool for 
purposes that are not intended for it, like using a circular saw to cut tree limbs or logs. 

 

Dress property. Do not wear loose clothing or jewellery. They can be caught in moving parts. Rubber gloves 
and non-skid footwear are recommended when working outdoors. Wear protective hair covering to contain 
long hair. 

 

Use safety glasses. Also use face or dust mask if the work area is dusty. 

 

Don't abuse the cord. Never carry the tool by the cord or yank it to disconnect it from the receptacle. Keep 
the cord away from sources of heat, oil and sharp edges. 

 

Secure the work piece. Use clamps or a vise to hold the work piece down. It’s safer than using your hand 
and it frees both hands to operate the tool. 

 

Don't overreach. Keep proper footing and balance at all times. 

 

Maintain tools with care. Keep tools sharp and clean for better and safer performance. Follow instructions for 
lubricating and changing accessories. Inspect tool cords periodically and if damaged, have them repaired by 
an authorised service facility. Inspect extension cords periodically and replace if damaged. Keep handles 
dry, clean, and free from oil and grease. 

 

Disconnect the tool when not in use, before serving, and when changing accessories such as blades, bits 
and cutters. 

 

Remove adjusting keys and wrenches. Form a habit of checking to see that keys and adjusting wrenches 
are removed from the tool before turning it on. 

 

Avoid unintentional starting. Don't carry a plugged-in tool with a finger on the switch. Be sure that the switch 
is off when plugging in. 

 

When tool is used outdoors, use only extension cords that are intended to be used outdoors.
