APPLYING POWER TO THE CORE DRILL
1. This core drill requires 115 VAC, 60 Hz power. Applying
power to the drill that is not specified will cause severe
damage to the core drill. Always read serial plate tag
before applying power to the core drill.
2. The power plug on this core drill is a 3-prong grounded
type plug.
ALWAYS connect this plug to a 3-prong
grounded receptacle.
NEVER plug this device into a
2-prong type receptacle. This will defeat the ground
circuit. The use of a 3-prong to 2-prong adapter is
strictly prohibited.
3. Connect the core drill's AC power cord to a 115 VAC
wall receptacle (Figure 9) that is protected by a 20
amp circuit breaker. For best results connect the power
cord to a GFCI receptacle.
