g.

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.

4) Power tool use and care

a.

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. 

b.

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.

c.

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. 

d.

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. 

e.

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. 

f.

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

g.

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. 

5) Service

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.
