WARNING
Do not attempt to start, detach or carry the tool without the plunger engaged. The motor assem- bly and the base could separate resulting in seri- ous injury.
WARNING
Position electrical cord clear of the base of hole saw to prevent cord damage and electrical 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
•The cord is rated as “W” or
•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 insula- tion or causing nearby objects to ignite.

2.Feed the hole saw into the pipe by turning feed wheel handle counterclockwise using moderate force so as to not overload the motor.
WARNING
Keep fingers and hands away from the saw blade. Do not reach across the hole saw or wear loose gloves or clothing that may become entan- gled and cause serious injury.
3.Rotate feed handle
WARNING
Forcing hole saw into pipe will not reduce cut- ting time. Therefore, do not overfeed saw while cutting. Doing so will result in premature saw failure or possible serious injury.
4.After completing the hole cut, retract the saw from the pipe by turning the feed wheel clockwise.
NOTE! When branching off an existing pipe system, use a hole saw with the 1/4″ pilot drill. The pilot drill helps retain the pipe slug in the hole saw.
5.Turn unit OFF by depressing ON/OFF switch to the OFF position.
6.Remove unit by:
A.Unclamping entire assembly or
B.Retrieving motor assembly by pulling plunger and then unclamping the base.
7.Brush away all metal chips created by the hole saw from the area around the hole.
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 mount- ing. They are useful when series of holes need to be aligned.
