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
