10. Machined flats are provided on the tool's base and
posts to assist leveling by using a torpedo level.
(Figures 17 & 18) Once the tool is properly posi-
tioned, tighten crank handle securely.
NOTE! The flat area with the RIDGID lettering in the
back of the base and the machined areas on
the side of the posts are designed for level
mounting. They are useful when series of holes
need to be aligned.

WARNING Never let go of the tool until the chain is
fully tightened. Doing so may result in the tool becoming
loose and falling, resulting in serious injury.
11. Lift the HC-300 motor assembly and mount on the
two posts by pushing firmly against the post springs
until you hear a click sound, indicating that the plunger
latch mechanism is properly engaged. (Figure 19)
NOTE! The click sound indicates that the plunger has
captured the base and the motor assembly.

WARNING
tool without the plunger engaged. The motor assembly
and the base could separate resulting in serious injury.
WARNING Position electrical cord clear of the
base of hole saw to prevent cord damage and elec-
trical shock.
12. Plug the hole cutting tool into the electrical outlet,
making sure to position the power cord along the
clear path. If the power cord does not reach the outlet,
use an extension cord in good condition. (See page 2.)
WARNING
To avoid electric shock and electrical fires, never
use and extension cord that is damaged or does not
meet the following requirements:
• The cord has a three-prong plug similar to shown
in Electrical Safety.
• The cord is rated as "W" or "W-A" if being used
outdoor.
• The cord has a wire thickness gauge that does
not exceed 14 AWG if shorter than 30 feet or
12 AWG if 30 feet or longer. If the cord is too long
or if the wire thickness is too small, the cord may
overheat, melting the cord's insulation or causing
nearby objects to ignite.
