Figure 16 – Tightening Chain

NOTE! The HC-300 features a spring loaded hooking mechanism that allows for easier tool pre-setting. Always tighten the chain using the swivel handle when the exact location of the cut is determined.

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 mount- ing. 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 becom- ing 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.
