28.  Maintain a balanced stance at all times so that 

you do not fall or lean against the cutter or 
other moving parts. Do not overreach or use 
excessive force to perform any machine 
operation. 

29. Use the right tool at the correct speed and 

feed rate. Rotate spindle clockwise for right-
hand tools, counterclockwise for left-hand 
tools. Do not force a tool or attachment to do a 
job for which it was not designed. The right 
tool will do the job better and more safely.

brush or compressed air to remove chips or 
debris — do not use your hands. 

33. Do not stand on the machine. Serious injury 

could occur if the machine tips over. 

34.  Never leave the machine running unattended. 

Turn the power off and do not leave the 
machine until it comes to a complete stop. 

35. Remove loose items and unnecessary work 

pieces from the area before starting the 
machine.

understand all user information listed on the 
coolant container and protect yourself 
accordingly.
