18. 

Do  not  use  tool  if  switch  does  not  turn  it  on  or  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.

 

Service 

24. 

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

 

 

VOLTAGE WARNING: 

Before connecting the machine to a power source (receptacle, outlet, etc.), be sure 

the voltage supplied is the same as that specified on the nameplate of the machine. 

A power source with voltage greater than that specified for the machine can result 

in SERIOUS INJURY to the user, as well as damage to the machine. If in doubt, 

DO  NOT  PLUG  IN  THE  MACHINE.  Using  a  power source with  voltage  less  than 

nameplate rating is harmful to the motor.

ADDITIONAL SAFETY RULES 

1.  Use  only  wheel  points  having  a  maximum  operating  speed  at  least  as  high  as 

“No-Load Speed” marked on the tool’s nameplate. 

2.  Check  the  wheel  point  carefully  for  cracks  or  damage  before  operation.  Replace 

cracked  or  damaged  wheel  point  immediately.

 

Run  the  tool  at  no  load  for  about  a 

minute, holding tool away from others. If wheel is flawed, it will likely  separate during 

this test. 

3.  Hold the tool firmly. 

4.  Keep hands away from rotating parts. 

5.  Make sure the wheel point is not contacting the workpiece before the switch is turned 

on. 

6.  Before  using  the  tool  on  an  actual  workpiece,  let  it  run  for  more  than  one  minute. 

(When mounting a new wheel point, let it run for more than three minutes.) Watch for 

vibration  or  wobbling  that  could  indicate  poor  installation  or  poorly  balanced  wheel 

point. 

7.  Watch out for flying sparks. Hold the tool so that sparks fly away from you  and other 

persons or flammable materials. 

8.  Do not leave the tool running. Operate the tool only when hand-held.
