Electrical Safety  
Use of these devices can reduce dust-related  
hazards.  
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.  
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.  
Do not expose power tools to rain or wet  
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.  
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.  
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

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.

SERVICE  
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.  
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.  
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.  
24. Follow instruction for lubricating and  
changing accessories.  
25. Keep handles dry, clean and free from oil and  
grease.
