5. Carefully lift the motor assembly and align the post
openings in the motor assembly with the posts of
the base assembly. Press the motor assembly on
until the plunger engages the post to retain the
motor assembly to the base. Confirm that the mo-
tor assembly is securely attached to the base. (See
Figure 9.)
6. The base of the HC-300 includes several machined
flats for use with levels for hole alignment. (See Fig-
ure 10.)

7. With one hand on the Hole Cutting Tool to stabilize
and guide it, slightly loosen the crank screw assem-
bly 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 jamming.
To mount the HC-300 on the pipe as a complete unit,
follow the steps indicated in the HC-450 section, using
the information in the HC-300 section on chain hook-
ing and alignment.

Powering the Hole Cutting Tool

1. Confirm that the ON/OFF switch is in the OFF posi-
tion.
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 out-
let, 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 com-
plies with H05VV-F, H07VV-F, H05RN-F, H07RN-F
types or IEC type design (60227 IEC 53, 60245 IEC
57).
• Has sufficient wire size (16 AWG / 1,5 mm
15,2 m or less, 14 AWG / 2,5 mm
15,2 m – 30,5 m long). Undersized wires can over-
heat, melting the insulation or causing a fire or
other damage.
