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. 

9. 

If operating a power tool in a damp location is 
unavoidable, use a ground fault circuit 
interrupter (GFCI) protected supply.

 Use of an 

GFCI reduces the risk of electric shock.   

Personal safety 

10. 

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. 

11. 

Use personal protective equipment. Always 
wear eye protection.

 Protective equipment such 

as dust mask, non-skid safety shoes, hard hat, or 
hearing protection used for appropriate conditions 
will reduce personal injuries.   

12. 

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.   

13. 

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. 

14. 

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

 This enables better control 

of the power tool in unexpected situations. 

15. 

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. 

16. 

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. 

 
 

Power tool use and care 

17. 

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. 

18. 

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. 

19. 

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. 

20. 

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. 

21. 

Maintain power tools. 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. 

22. 

Keep cutting tools sharp and clean.

 Properly 

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

23. 

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. 

Battery tool use and care 

24. 

Recharge only with the charger specified by 
the manufacturer.

 A charger that is suitable for 

one type of battery pack may create a risk of fire 
when used with another battery pack. 

25. 

Use power tools only with specifically 
designated battery packs.

 Use of any other 

battery packs may create a risk of injury and fire. 

26. 

When battery pack is not in use, keep it away 
from other metal objects, like paper clips, 
coins, keys, nails, screws or other small metal 
objects, that can make a connection from one 
terminal to another.

 Shorting the battery 

terminals together may cause burns or a fire. 

27. 

Under abusive conditions, liquid may be 
ejected from the battery; avoid contact. If 
contact accidentally occurs, flush with water. If 
liquid contacts eyes, additionally seek medical 
help.

 Liquid ejected from the battery may cause 

irritation or burns.
