The TS55 saw comes equipped with a removable Plug-It 

power cord. To install the power cord, insert the cord into 

the inlet on the tool with the key and keyway aligned, and 

twist the locking ring. Reverse the procedure to remove the 

cord.

  NOTICE: Make sure to fully tighten the plug-it cord 

a full quarter-turn until it clicks. If the plug is not 

fully locked, the socket and cord can overheat and be 

damaged.

To prevent unexpected start-ups, the power switch has an 

integral safety interlock. Before the saw can be started or 

plunged, the plunge release must be engaged.
To start the saw, push up on the plunge release, and pull 

back on the trigger. Once the trigger has been engaged, you 

no longer need to hold the plunge release raised.

Most circular saws do not have variable speed electronic 

controls like the TS55 has. For this reason, many new saw 

owners aren’t accustomed to the slight “growling” sound 

of the motor’s gears when they first operate the saw. This 

sound is normal and not an indication that something is 

wrong with the tool.
The sound is the result of the gears interacting with the 

electronic speed control. The electronic controller in the 

motor controls the motor speed by turning it On and Off 

very rapidly. This form of speed control is called “Pulse 

Width Modulation” (PWM), and is common in most power 

tools with a variable speed control. When there is little or 

no load on the sawblade, the pulsations of the motor cause 

the gears to rapidly engage and disengage (called lash), and 

this is the sound you are hearing.
