7. With one hand on the Hole Cutting Tool to stabilize
and guide it, slightly loosen the crank screw assembly
to allow final positioning of the tool. Align the pilot
drill with the desired cut location, and firmly tighten the
crank screw assembly. Do not remove your hands
from the Hole Cutting Tool until you have confirmed
that it is securely attached to the pipe. The Hole
Cutting Tool must be securely and squarely attached
to the pipe to help reduce the risk of hole saw jam-
ming.
To mount the HC-300 on the pipe as a complete unit, fol-
low the steps indicated in the HC-450 section, using
the information in the HC-300 section on chain hooking
and alignment.
Powering the Hole Cutting Tool
1. Confirm that the ON/OFF switch is in the OFF position.
2. Makes sure that the power cord is routed out the back
of the tool away from the chuck and work area. Run
the cord along the clear path to the outlet, and with dry
hand plug in. Keep all connections dry and off the
ground. If the power cord is not long enough, use an
extension cord that:
• Is in good condition
• Has a three prong plug similar to that on the tool.
• Is rated for outdoor use and contains a W or W-A in
the cord designation (i.e. SOW), or complies with
H05VV-F, H05RN-F types or IEC type design
(60227 IEC 53, 60245 IEC 57).
• Has sufficient wire size (16 AWG (1.5mm
(15.2m) or less, 14 AWG (2.5mm
(15.2m – 30.5m) long). Undersized wires can over-
heat, melting the insulation or causing a fire or other
damage.
