OPERATION & MAINTENANCE / 3
VENTILATION: The purpose of ventilation is the establishment of a safer interior environment through planned and
systematic removal of heat, smoke, and toxic gases and their replacement with fresh air. It is an offensive technique that,
when accomplished early and effectively, can speed tactical operations.
As fire develops within a structure, several conditions result. First, the temperature and toxicity of the atmosphere increase
rapidly. Then radiated and convected heat result in flashover and the subsequent rapid spread of fire throughout the struc-
ture.
Without ventilation, the fire will develop a super-heated, oxygen-deficient, and fuel-rich environment ripe for backdraft.
Firefighters can minimize these conditions with proper ventilation techniques and proper tools. Knowledge, training and
Cutters Edge Fire Rescue Saws are the proper tools.
Cutters Edge Fire Rescue Saws are designed and built exclusively for use by TRAINED FIREFIGHTERS. Although Cutters
Edge Fire Rescue Saws are essentially modified chain saws, their use and applications differ substantially. This manual is
provided to assist you in learning the safe and proper set-up, operation and maintenance of your new Cutters Edge Fire
Rescue Saw. However, you should not attempt to use this tool without knowledge of the safe and proper application of
power saws in fighting fires. Cutters Edge recommends that you view the video edition of this training manual that further
ill
ustrates these steps and techniques. This manual is in no way intended to replace the chainsaw manuals, rather it should
be used as a supplemental manual dealing with the specific applications of this specialized tool. Nor are the guidelines for
operational procedures described herein intended to contradict the standard operating procedures (SOP) of your individual
fire department.
For more information about the principles and techniques of ventilation, we recommend the book "FIRE RESCUE METH-
ODS AND TECHNIQUES", by Los Angeles City Fire Department Battalion Chief John Mittendorf. There are order forms for
both the video and Chief Mittendorf's book at the back of this manual.
RESCUE:
With the introduction of the BULLET® CHAIN, applications for your CUTTERS EDGE® FIRE RESCUE SAW
have increased dramatically!
Ventilation, Forcible Entry, Storm Damage, Rescue, Crash Rescue (Aircraft & Automobile) and conventional chain saw and
rotary saw applications are some of the many operations your saw can be used in.
While chain wear and damage may be accelerated when cutting materials other than wood. Your BULLET® CHAIN
equipped saw is capable of cutting most building materials including nails, sheet metal and some lightweight concretes. It
i s capable of cutting automotive sheet metal, automotive glass, plastics, fiberglass and many composite materials. It can
cut aircraft skin, cockpit and aircraft windows and even some aircraft structural materials.
*
There are of course limitations, but your CUTTERS EDGE FIRE RESCUE SAW with BULLET® CHAIN will cut a wide vari-
ety of materials under the most severe fireground and rescue scene conditions.
This manual will take you through each step of assembling the saw when you receive it, how to properly operate the saw,
and how to clean and maintain the saw after use.
Before attempting to assemble or use your saw, we strongly suggest that you view the optional video completely and read
• When materials other than wood are cut, increased wear and damage should be anticipated. The possibility of chain breakage also increases. All mate-
rials listed have been successfully cut under controlled conditions and during actual fireground and rescue incidents. However, quantlty, composition of
specific materials, operator experience, existing conditions, and unknown factors can adversely affect the outcome.
the manual completely. Then carefully follow the instructions in this manual as you proceed to prepare your Cutters Edge
Fire Rescue Saw for use.
WARNING
Please take note of the warnings in this manual and the
warning labels attached to various parts of the saw and
its accessories. Read these warnings and heed their
advice. Failure to do so could result in injury to you
and/or damage to the saw. Any warranties provided by
the manufacturer will not cover abuse, neglect or mis-
handling of the saw.

4 / CUTTERS EDGE FIRE RESCUE SAWS
WARNING
Beware of kickback!
There are two types of kickback that can be encountered with the improper use of a chainsaw or the Cutters
Edge Fire Rescue Saw. Both types are the result of an equal and opposite reaction that occurs when the chain
i
s suddenly stopped. This kickback movement is so fast that the operator cannot react quickly enough to avoid
serious injury.
ROTATIONAL KICKBACK is the violent reaction which occurs when the chain at the upper section of the nose
i
s suddenly stopped, thereby dangerously driving the bar nose in an upward arc towards the operator.
LINEAR KICKBACK i
s a push reaction, which can occur with the saw blade buried in the cut when the cut clos-
es, pinching the chain along the top rails of the bar.
KICKBACK MAY OCCUR WHEN:
The upper section of the nose or tip of the guide bar touches an object.
The wood closes in and pinches the saw chain in the cut.
Tip contact in some cases may cause a lightning-fast reverse reaction, kicking the guide bar up and back
towards the operator. Pinching the chain along the top of the guide bar may push the saw rapidly back towards
the operator. Either of these reactions may cause you to lose control of the saw, which could result in serious
personal injury.
Cutters Edge builds several safety devices into their saws, but you should not rely exclusively upon these safety
devices. As a Fire Rescue saw user, you should take several steps to keep your cutting jobs free from accident
or injury:
1)
With a basic understanding of kickback, you can reduce or eliminate the element of surprise. Sudden
surprise contributes to accidents.
2) Keep a good firm grip on the saw with both hands when the engine is running. Use a firm grip with thumbs
and fingers encircling the chainsaw handles. A firm grip will help you reduce kickback and maintain control
of the saw. Don't let go.
3) Make sure that the area in which you are cutting is free from obstructions. Do not let the kickback zone of
the guide bar contact any obstructions while you are operating the saw.
4) For ventilation and rescue cutting, always cut at full RPMs.
5) Do not overreach or cut above shoulder height
6) Follow manufacturer's sharpening and maintenance instructions for the BULLET®
CHAIN.
7) Only use replacement bars and chains specified by the manufacturer or the equivalent.

CUTTERS EDGE FIRE RESCUE SAW
Cutters Edge Fire Rescue Saws are shipped fully assembled. The 12", 16" and 20" RS Models come with a protective
scabbard covering the BULLET® CHAIN. The GUARD/DEPTH GAUGE® on the D6 and D8 Models covers the BULLET®

Part One
Set-Up
This section will cover assembly of the saw and preparation
for operation. All necessary tools and equipment have been
included with your saw.
THE CHAIN BRAKE
The chain brake is designed to stop the rotation of the chain
in less than one-twentieth of a second. If kickback should
occur, the violent reverse action will drive the chain brake
handle back into the operator's top hand, engaging the
chain brake and stopping movement of the chain. We utilize
a sealed inertia chain brake which works on the same prin-
ciple as an auto seat belt.
The chain brake has three positions-
3. 1. 2.

I
l
Fig. 1. Center - Neutral position, chain brake disengaged.
During operation, the brake is in the neutral, or center posi-
tion (Fig. 1). This allows the chain to turn freely.
Fig. 2. Forward position, chain brake engaged.
When engaged, the chain brake handle is in the fully for-
ward position (Fig. 2). At this point, the chain will not turn.
CAUTION
If the saw is run with the chain brake engaged - the
clutch, oil pump, and chain brake will be damaged.
3. 1. 2.
Fig. 3. Back position, to disengage chain brake.
To disengage the chain brake, pull the chain brake handle
back completely to the saw's top handle (Fig. 3). It is
important that the chain brake handle comes to full
contact with the saw's handle. Any obstructions, such
as your hand, will prevent disengagement of the chain
brake. Once you have pulled the chain brake handle back
completely, let go and it will snap back to the center or oper-
ating position.
THE CLUTCH COVER
Place the power head on your work surface, use the
scrench tool to loosen the two clutch cover nuts (Fig. 4).
Fig. 4. Clutch cover nuts.
Remove the clutch cover. Now you can visually inspect the
chain brake to see how it operates. When engaged, the
chain brake band grabs the spinning clutch drum and
i mmediately stops it.

THE BAR PLATES
Remove the outer bar plate. Note that the two bar plates
are similar (Fig. 5) but that the inner bar plate is smaller and
has an additional slot that allows oil to reach the chain.
Fig. 5. Inner tear plate, with oil slot
It is imperative that the inner plate with the oil
slot is installed properly or the flow of bar oil will
be blocked and damage to the saw and chain will
occur.
INSTALLING THE BAR AND CHAIN
Next, install the bar by first adjusting the chain tensioning
screw fully back (using the scrench tool, turn the tensioning
screw counter clockwise to move the tensioner back
toward the clutch drum)
(Fig. 6). Slide the guide bar onto
the 2 bar studs, aligning the tensioner with the adjusting
hole in the bar.

INSTALLATION OF THE CHAIN
To install the chain, first align the chain so that the cutters
are pointing toward the tip of the bar as they lay on the top
of the bar. Slip the chain onto the clutch sprocket rim (Fig.
8). Then 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.
Now replace the outer bar plate.
Replace the clutch cover, tightening the clutch cover nuts
only finger tight.
SECURING THE BAR & CHAIN
Wearing gloves or with a shop rag protecting your hand,
pull up on the tip of the bar. While holding up the bar tip,
tighten the chain tension adjustment screw by turning it
clockwise.
While still holding up the bar tip, tighten the
clutch cover nuts (Fig. 9). Holding up the tip of the bar takes
out any slack between the bar mounting slot and the two
mounting studs. This will eliminate any upward movement
of the bar when cutting pressure is applied at the bottom of
the bar. Any such upward movement of the bar would cause
the chain to loosen.
Fig. 9.Tightening the clutch cover nuts.
CHAIN TENSION
Proper chain tension is a key factor in reducing carbide
breakage and increasing guide bar life. Proper chain ten-
sion has the chain as tight as possible without restrict-
ing chain movement.
At proper tension, the chain should move along the bar
freely.
You should feel only the resistance of the sprocket
and clutch drum turning. If the chain does not move
smoothly i.e., catches or requires excessive force to move,
it is too tight. At proper tension, the chain is in full contact
with the bar along the bottom rails, there is no "sag".
At the midpoint along the bottom rails, when pulling down
on the chain, you should be able to pull the chain away from
the rails - to the distance where point of the drive link is "just

Next remove the bar and chain oil tank cap and fill the tank
with bar and chain oil. Replace the cap.
You do not need special detergent oils; as the chain pro-
duces high enough temperatures to prevent the buildup of
tars on the chain.
WARNING

WARNING
Do not mix the bar and chain oil with diesel or
kerosene as this actually reduces its lubricating
ability and does not reduce tar buildup.
We recommend the use of Cutters Edge Bar & Chain Oil for
its excellent lubricating and anti-sling properties. This oil
has been developed to provide high flash and fire points for
optimum performance during harsh fire-ground applica-
tions, with high flow properties for use even in extreme cold
temperatures. This anti-rust, anti-wear formula is recom-
mended for use on all Fire Rescue saws and other con-
ventional chainsaw.
THE FILTERS
The filter element is coated at the factory and needs no oil
prior to this first use.
THE MOMENTARY CONTACT SWITCH
The saw is now ready to start. Before starting the saw, you
should know how to stop it. The Cutters Edge Fire Rescue
Saw is equipped with a momentary contact switch that is
always in the "on" position (Fig. 11). To stop the saw, push
the momentary contact switch to the right. This kills the saw.
When released, the switch will snap back to the "on" posi-
tion automatically.
Fig. 11. Momentary contact switch.
I MPORTANT
Before starting the saw, it is important to note that
you should not run the saw at full throttle until after
breaking in the engine, which will be the procedure
following running-in the chain.
STARTING THE SAW
OPERATION & MAINTENANCE / 9
To start the saw, place it on the ground. If you intend to run-
i
n the chain at this point, you should perform these steps
outdoors or in a well-ventilated area.
NOTE:
Do not start the saw with the chain brake engaged.
Be sure the chain brake is disengaged by pulling
back the chain brake handle until it contacts the
front of the full wrap handle. (See page 8.)
Grip the top handle firmly and step on the outer edge of the
back handle (Fig. 12).

Grasp the starter handle and pull sharply upward a few
times until the engine catches.
Push the choke in.
Pull the handle again. The engine will start.
Quickly squeeze and release the trigger to set the idle.
WARM START (engine still warm from previous use)

NOTE
Note that you must depress the safety lock on top
of the handle to be able to pull the trigger (Fig. 14).
The trigger cannot be pulled without depressing
this safety lock.
Fig. 13. Throttle lock.
You may stop the saw with the momentary contact switch
or you may continue on to the chain run-in procedure.
RUNNING-IN THE CHAIN
The next step is running-in the chain. This important proce-
dure stretches and fully lubricates the chain.
Start the saw and run it at one-half to three-quarter speed
for approximately 10 minutes or until the bar and chain
begin to smoke.
Now turn off the saw. The chain has reached its operating
temperature. You will notice that the chain has sagged (Fig.
14). Before readjusting, allow the chain to cool down for
three to five minutes, or until it is cool enough to touch with-
out discomfort.
Fig. 14. The chain will sag when hot.
Once it is cool enough to handle, readjust the chain to the
proper tension.
NOTE
Repeat this entire chain adjusting procedure once
more.
Running-in the chain will remove approximately 75% of
chain stretch. However, under normal use the chain will
continue to stretch throughout its life. Re-check the chain
tension during prolonged use and after each use.
BREAKING IN THE ENGINE
Proper breaking-in of the engine is a crucial step
in the set-up of your saw. This procedure allows
the cylinder to coat with oil and seat the piston
ring properly. If you skip this procedure and run
the saw at full throttle, severe damage to the
engine can occur.
NOTE:
Even though the chain will not turn at idle and no
bar and chain oil will be pumped, this break-in
procedure must be performed with the bar and
chain installed and with the bar and chain oil tank
filled. Also be sure the chain brake remains disen-
gaged throughout the procedure.
To perform the initial engine break-in, start the saw and let
it idle through a complete tank of fuel. It is advisable to
briefly operate the saw at full throttle periodically during this
procedure to avoid "loading up". (Do not run the engine at
full throttle,
with "no load," for more than 2 seconds or
engine damage may occur!)
This is an initial engine break-in only. The engine will not be
completely broken-in until it has been operated through
several tanks of fuel.

Installation, Operation & Maintenance
CUTTERS EDGE® D-8 & D-6 GUARD/DEPTH GAUGE®
D-8 fits 20"bar, has8"maximum cutting depth. D-6 fits 16"bar, has6"maximum cutting depth.

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
i 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
i nstalling it on a new Cutters Edge Saw or upgrading your
older Cutters Edge Saw. Take the time to read these
i 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
i 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
i 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.

Fig. 16. Slip the spacers between two cutters.
Position the outer section properly, with the spacers
between the cutters on the chain. Tap it into place.
The Adjusting Knob
Place the nylon washer and serrated washer onto the knob
shaft. Insert the knob shaft through the slot in the outer
section then the bar slot and screw into the threaded hole.
Chain Tensioning
Slide the D-8 back all the way to the guard/deflector and
check the chain tension. If the chain needs tensioning,
loosen the bar nuts and the adjusting knob. Adjust the
chain tension as needed, using the ball driver.
Fig. 17 Use the ball-driver to tension the chain.
Retighten the bar nuts, then slide the D-8 out to its full
extension.
Your Cutters Edge Fire Rescue Saw with the D-8 Guard/
Depth Gauge installed is now ready for use.
NOTE
For detailed instructions on the uses and applica-
tions of ventilation saws, please refer to your
Cutters Edge Fire Rescue Saw Operations and
Maintenance Manual.
Operation of the D-8
OPERATION & MAINTENANCE / 13
You can now adjust the D-8 to various depths of cut. If the
saw is running, first set the saw's chain brake. Then loosen
the adjusting knob. Slide back the outer section of the D-8
to the desired setting on the depth scale. Retighten the
adjusting knob and release the chain brake. You are ready
to cut.
Fig. 18.
Set the D-8 to the necessary depth.
NOTE
Since the D-8 completely covers the cutting chain
when it is fully extended, you can now start your
saw on the ground and then carry it up to the roof
while it is running. This eliminates the need to re-
start the saw after you are in position on the roof.
I nspection Cut
On the roof, first make an inspection cut to determine the
thickness of your roofing materials. Slide back the D-8 to
i
ts fully retracted position, then make the inspection cut as
you normally would, keeping the saw at ninety degrees to
the rafter, feeling for and rolling the rafter.
Set your chain brake. Visually determine the thickness of
the roofing materials and then adjust the D-8 to the
necessary setting. Release the chain brake and make
your ventilation cuts.
Cutting deeper than the D-8 setting
Even with the D-8 set to a pre-determined depth you can
increase the depth of your cut-without changing the set-
ting-by increasing the angle of the saw to the roof sur-
face. While cutting at the normal forty-five degree angle,
the saw will cut to the depth you have set. But by raising
the angle of the saw up to ninety degrees, you can cut up
to one-half inch deeper for every one inch you have set on
the D-8 scale.

14 / CUTTERS EDGE FIRE RESCUE SAWS
Fig. 19. Depth of cut at forty-five degrees.
In Figure 19, above, the saw is set for a cut of
approximately 2" inches. At the proper cutting angle of 45
degrees, the saw penetrates to that depth.
But as you can see in Figure 20, below, the saw penetrates
another half-inch for each inch set on the D-8-in this case
another inch, down to approximately 3" inches-when the
cutting angle is raised to ninety degrees.
Fig. 20. Depth of cut at ninety degrees.
Removing the D-8.
The process to remove the D-8 for cleaning and/or to use
your Cutters Edge saw for conventional cutting purposes
is simple and basically a reversal of installation:
1. Set the chain brake on to lock the chain and bar in
position.
2. Remove the adjusting knob.
3. Pull off the outer section of the D-8.
4. Remove the bar nuts.
5. Remove the allen-head screws from the guard/deflector
side of the D-8.
6. Pull off the inner section of the D-8.
7.
Rethread and retighten the bar nuts.
8.
Release the chain brake.
Your saw is now ready for use as a conventional chain
saw.
NOTE
If
you are removing the D-8 to use your saw for
conventional cutting; first set the chain brake. This
will prevent the need to retension the chain after
you have removed the D-8.
Cleaning the D-8
I
t's important that the D-8 be cleaned after each use, along
with your Cutters Edge-Fire Rescue Saw.
To clean the D-8, simply remove it as you would to config-
ure your saw for conventional cutting. Wipe off all inner and
outer surfaces of the D-8.
NOTE
Cleaning may also be done in a parts washer.
If you should have questions about the installation, opera-
tion or maintenance of your D-8 or any Cutters Edge prod-
uct, call our service department at 1-800-433-3716.

end of the sling to the back handle in the same manner.
Once on the roof, remove the sling and place it in your
pocket or out of your way.
WARNING
Never operate the Cutters Edge Fire Rescue Saw
with the sling attached.

16 / CUTTERS EDGE FIRE RESCUE SAWS
IMPORTANT
Always operate the saw with a minimum of two
people on the roof for safety. One should operate
the saw and the other act as backup and as eyes
and ears for the operator.
Always wear full protective gear, along with a face
shield or goggles.
Sound the roof for the safest operator position.
Select and prepare an alternate escape route.
Position yourself properly and prepare to cut.
ONE-STEP STARTING PROCEDURE
Since you have properly warmed up the saw, you can start
it now using the One-Step Starting Procedure. After posi-
tioning yourself properly, securely holding the saw in place,
simply pull the starter handle upward (Fig. 22). The saw will
start and you will be ready to cut.
Fig. 22. One-Step Starting
CUTTING
Never cut with the saw directly in line with your
body or across your body.
When ready to begin cutting, choose a position that is safe
and comfortable. Cut with the saw held to one side of
your body, locking your top elbow, if possible. Avoid cutting
with the saw directly in line with or across your body.
PENETRATION CUT
To begin your penetration cut, hold the saw at an angle of
approximately forty-five degrees to the roof (Fig. 23). This
positions the highest number of cutters in contact with the
roof surface for optimum penetration speed.
Fig. 23. Penetrate at approximately 45 degrees.
Attempting to penetrate with too high an angle
may cause kickback, while penetrating with too
l ow an angle will actually increase penetration
ti me and cause unnecessary wear to the cutters.
Plunge the bar in aggressively for penetration, but don't
penetrate any deeper than necessary. This will prevent the
i nadvertent cutting of hidden dangers, such as rafters,
wiring or braces.
After you have penetrated the roof surface, increase the
angle of your saw up to ninety degrees. This places a
greater number of cutters in contact with the broad surfaces
of the rafters, increasing your sensitivity of feel.
With practice you will get a feel for boring through the roof
surface. If it feels like it is taking too long to penetrate, you
may be directly on a rafter. Simply move your cut over a few
i nches and begin to cut again.
"ROLLING THE RAFTERS"
When you feel a rafter, pull the saw up and allow it to cut
only the roof decking as you roll over the rafter (Fig. 24).
Then return to your previous depth of cut until you
encounter another rafter to roll (Fig. 25). This preserves roof
i ntegrity and provides you with another measure of protec-

tion. With practice, you will be able to do this quickly and
efficiently.

Criss-cross your cuts at their intersections. The overlapping
of your cuts will allow for easy removal or louvering of the
roof material (Fig. 26).

VENTILATION CUTS
OPERATION & MAINTENANCE / 17
There are many types of Fire Rescue cuts. We will demon-
strate some of them for your reference. For more informa-
tion about the principles and techniques of Fire Rescue,
please refer to the Cutters Edge Training Video and its sup-
plemental manual. We also recommend the book "VENTI-
LATION METHODS AND TECHNIQUES" by Battalion
Chief John Mittendorf. Order forms are in the back of this
manual.
I NSPECTION CUT
The 45 Degree Inspection Cut-or View Hole-is a trian-
gular cut through the roof decking and rolled over one rafter
at 45 degrees to any exterior wall (Figs. 27A & 27B). This
cut allows you to identify the type of smoke and the roof
composition, and to determine rafter direction.

Fig. 278. Inspection Cut.

LOUVER
To louver, start with a head cut perpendicular to the rafter
direction, rolling any rafters. The rafters will become the piv-
ots or hinges to louver the cut sections.
Make parallel longitudinal cuts approximately halfway
between and parallel to the rafters. Be sure to criss-cross
your vertical and horizontal cuts at their intersections.
Complete the louver cut by cutting another perpendicular
cut across the bottom, rolling the rafters again. Then louver
or hinge the sections, using the rafter as the pivot point (Fig.
28).

PULLBACK
The Pullback Method follows the same procedure as a lou-
ver cut, but you would then remove the roofing material
completely (Fig. 29).
Fig. 29. Remove roof materials for the pullback
STRIP
A Strip-or Trench Cut-would normally be used across the
width or length of the roof. You either cut between the
rafters and let the roofing material drop into the structure, or
cut across the rafters, being sure to roll the rafters, then
l ouver or pull back the roofing material.

CUTTING OTHER MATERIALS
Your Cutters Edge Fire Rescue Saw may be used to cut
many other materials such as downed trees, storm dam-
age, cutting shoring and cribbing, removal of rubble from
building collapse, auto accidents, aircraft crash rescue, and
forcible entry, to name a few.
To cut through other materials, remember the basic opera-
tional rules of your Cutters Edge Fire Rescue Saw. With
practice, you will develop a feel for the saw, enabling you to
"read" the material you are cutting. Remember to always
maintain full RPMs as you cut, and don't force the cut.
Remember the basic rules for safe operation of your
Cutters Edge Fire Rescue Saw:
1) Wear full turn-outs with gloves, face shield or goggles.
2) Keep a firm grip on the saw.
3) Avoid cutting across your body.
4) Cut with full RPMs.
5) Avoid the bar's kickback zone.
6) Do not attempt to operate saw without completion of
your fire department's training for the use of a power
tool.
