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 residual current device 
(RCD) protected supply.

 Use of an RCD 

reduces the risk of electric shock.   

10. 

Use of power supply via a RCD with a rated 
residual current of 30mA or less is always 
recommended. 

Personal safety 

11. 

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. 

12. 

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.   

13. 

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.   

14. 

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. 

15. 

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

 This enables better control 

of the power tool in unexpected situations. 

16. 

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. 

17. 

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 

18. 

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. 

19. 

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. 

20. 

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. 

21. 

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. 

22. 

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. 

23. 

Keep cutting tools sharp and clean.

 Properly 

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

24. 

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. 

Service 

25. 

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. 

26. 

Follow instruction for lubricating and 
changing accessories. 

27. 

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