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.

Properly maintained cutting tools with 

sharp cutting edges are less likely 

to bind and are easier to control.

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.
