operating a power tool.

 Distractions can cause 

you to lose control. 

Electrical Safety 

4. 

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. 

5. 

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. 

6. 

Do not expose power tools to rain or wet 
conditions.

 Water entering a power tool will 

increase the risk of electric shock. 

7. 

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. 

8. 

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 

9. 

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. 

10. 

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. 

11. 

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. 

12. 

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. 

13. 

Do not overreach. Keep proper footing and 
balance at all times.

 This enables better control 

of the power tool in unexpected situations. 

14. 

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. 

15. 

If devices are provided for the connection of 

dust extraction and collection facilities, 
ensure these are connected and properly used.

 

Use of these devices can reduce dust-related 
hazards. 

Power tool use and care 

16. 

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. 

17. 

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. 

18. 

Disconnect the plug from the power source 
and/or the battery pack 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. 

19. 

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. 

20. 

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. 

21. 

Keep cutting tools sharp and clean.

 Properly 

maintained cutting tools with sharp cutting edges 
are less likely to bind and are easier to control. 

22. 

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 
those intended could result in a hazardous 
situation. 

SERVICE 

23. 

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. 

24. 

Follow instruction for lubricating and 
changing accessories. 

25. 

Keep handles dry, clean and free from oil and 
grease.
