GENERAL SAFETY PRECAUTIONS

 

 

WARNING! 

When using electric tools, basic safety precautions should always be followed 

to reduce the risk of fire, electric shock and personal injury, including the following. 
 

 

 

 

 

 

 

 

 

 

Read all these instructions before operating this product and save these instructions. 

 
For safe operations:

  

 

1. Keep work area clean. Cluttered areas and benches invite injuries. 
2. Consider work area environment. Do not expose power tools to rain. Do not use power tools in 
damp or wet locations. Keep work area well lit. Do not use power tools where there is risk to cause fire 
or explosion. 
3. Guard against electric shock. Avoid body contact with earthed or grounded surfaces. (e.g. pipes, 
radiators, ranges, refrigerators). 
4. Keep children and infirm persons away. Do not let visitors touch the tool or extension cord. All 
visitors should be kept away from work area. 
5. Store idle tools. When not in use, tools should be stored in a dry, high or locked up place, out of 
reach of children and infirm persons. 
6. Do not force the tool. It will do the job better and safer at the rate for which it was intended. 
7. Use the right tool. Do not force small tools or attachments to do the job of a heavy duty tool. Do not 
use tools for purposes not intended. 
8. Dress properly. Do not wear loose clothing or jewelry; they can be caught in moving parts. Rubber 
gloves and non-skid footwear are recommended when working outdoors. Wear protecting hair 
covering to contain long hair. 
9. Use eye protection. Also use face or dust mask if the cutting operation is dusty. 
10. Connect dust extraction equipment. If devices are provided for the connection of dust extraction 
and collection facilities ensure these are connected and properly used. 
11. Do not abuse the cord. Never carry the tool by the cord or yank it to disconnect it from the 
receptacle. Keep the cord away from heat, oil and sharp edges. 
12. Secure work. Use clamps or a vise to hold the work. It is safer than using your hand and it frees 
both hands to operate tool. 
13. Do not overreach. Keep proper footing and balance at all times. 
14. Maintain tools with care. Keep cutting tools sharp and clean for better and safer performance. 
Follow instructions for lubrication and changing accessories. Inspect tool cords periodically and if 
damaged, have it repaired by authorized service center. Inspect extension cords periodically and 
replace, if damaged. Keep handles dry, clean, and free from oil and grease. 
15. Disconnect tools. When not in use, before servicing, and when changing accessories such as 
blades, bits and cutters. 
16. Remove adjusting keys and wrenches. Form the habit of checking to see that keys and adjusting 
wrenches are removed from the tool before turning it on. 
17. Avoid unintentional starting. Do not carry a plugged in tool with a finger on the switch. Ensure 
switch is off when plugging in. 
18. Use outdoor extension leads. When tool is used outdoors, use only extension cords intended for 
outdoor use. 
19. Stay alert. Watch what you are doing. Use common sense. Do not operate tool when you are tired. 
20. Check damaged parts. Before further use of the tool, a guard or other part that is damaged should 
be carefully checked to determine that it will operate properly and perform its intended function. Check 
for alignment of moving parts, free running of moving parts, breakage of parts, mounting and any other 
conditions that may affect its operation. A guard or other part that is damaged should be properly 
repaired or replaced by an authorized service center unless otherwise indicated in this instruction
