12 / CUTTERS EDGE FIRE RESCUE SAWS

The Cutters Edge D-8 GUARD/DEPTH GAUGE® has

been designed, engineered and carefully tested to provide

you with increased safety and efficiency in firefighting

applications.

While in its fully extended position, the D-8 completely

covers the guide bar and cutting chain, protecting you from

accidental contact with the spinning chain. Even while

retracted and set for specific depths of cut, the D-8 covers

all but that chain at the tip exposed for cutting.

The D-8 allows you to set a specific depth of cut,

preventing you from cutting any deeper than is absolutely

necessary. This prevents you from weakening the roof

structure and prevents exposure to hidden hazards like

electrical wiring.

These features of the D-8 are designed to provide you with

ncreased confidence as you make your ventilation cuts.

You will be able to cut faster and you will have less to worry

about. You can concentrate more on your cuts, your cutting

position, and your environment.

Of course, as with any tool, it is only as safe as its opera-

tor.

You must be careful to take all necessary safety pre-

cautions and to follow all safe operating procedures.

These instructions are intended to help you to install and

to safely utilize the Cutters Edge D-8, whether you are

nstalling it on a new Cutters Edge Saw or upgrading your

older Cutters Edge Saw. Take the time to read these

nstructions carefully. Familiarize yourself with the parts

and components of the D-8. If you are not experienced in

the use of Fire Rescue saws, refer to the Cutters Edge Fire

Rescue Saw Operation and Maintenance Manual and

Training Video.

NOTE

If you are upgrading your saw with a D-8 Kit:

Before proceeding you will first need to remove

the chain tension adjusting screw and replace it

with the alien head chain tension adjusting screw

supplied with your D-8.

You will also need to remove and replace the old

guard/deflector with the new guard/deflector sup-

plied with your D-8.

Prepare Your Saw

To begin installation of your D-8, remove the chain brake

cover, guide bar and chain according to the instructions in

your Cutters Edge Fire Rescue Saw Operations and

Maintenance Manual.

The Slotted Guide Bar

Adjust the chain tensioning screw fully back, then slide the

new, slotted guide bar into position, aligning the chain ten-

sioner with the adjusting hole in the bar.

The Chain

First

make sure that the chain cutters are pointing toward

the tip of the guide bar as they lay on the top of the bar. Slip

the chain into the groove of the guide bar, again verifying

that the top cutters point toward the tip of the bar.

Pull the chain around the bar to be sure the drive links are

properly seated in the drive sprocket.

NOTE

At this point you need not worry about tensioning

the chain, as it is easy to do so after the D-8 is

nstalled.

Now replace the outer bar plate.

Replace the clutch cover.

The D-8 Inner Section

Place the inner section of the D-8 over the chain and guide

bar, sliding the holes in the D-8 onto the bar mount bolts.

Snugly tighten the bar nuts.

Now align the holes in the flange of the D-8 with the holes

n the saw's guard/deflector. Carefully insert and tighten the

alien-head bolts with the special ball-driver included with

your D-8.

Fig. 15. Use the ball-driver to tighten the alien-head bolts.

The D-8 Outer Section

Place the D-8 outer section onto the bar.

WARNING

To avoid damaging the chain or the D-8, be care-

ful to slip the spacers that are inside the nose of

the D-8 outer section between two chain cutters.
