Introduction
VENTILATION:
Cutters Edge Fire Rescue Saws are designed and built exclusively for use by trained firefighters. Although
Cutters Edge Fire Rescue Saws are essentially modified chainsaws their use and applications differ substantially. This manual is
provided to assist you in learning the safe and proper set-up, start-up 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 applications of power saws in fighting fires.
This manual is in no way intended to replace the basic chainsaw manual; rather it should be used as a supplemental manual dealing
with the specific applications of this specialized firefighting tool. Nor are the guidelines for operational procedures described herein
intended to contradict the standard operating procedures (SOP) of your individual fire department.
There are a number of excellent training publications available about the principles and techniques of ventilation. Cutters Edge
recommends the book “FIRE RESCUE METHODS AND TECHNIQUES”, by Los Angeles City Fire Department Battalion Chief (Ret.),
John Mittendorf
The purpose of ventilation is to establish a safer interior environment through planned and systematic removal of heat, smoke, and
toxic gases and their replacement with fresh air. Ventilation is an offensive technique that, when accomplished early and effectively, can
speed tactical operations and provide a safer environment for firefighters.
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 structure. Without
ventilation the fire will develop a super-heated, oxygen deficient and fuel-rich environment ripe for backdraft.
Firefighters can minimize these dangerous conditions with proper ventilation techniques and proper tools. Knowledge, training and
Cutters Edge Fire Rescue Saws are the proper tools.
RESCUE:
With the development of the BULLET® CHAIN, applications for your CUTTERS EDGE
®
FIRE RESCUE SAW have
increased dramatically compared to conventional chain saws and rotary saws.
Your Fire Rescue Saw can be used for many operations, including: Ventilation, Forcible Entry, Storm Damage, Rescue, Crash Rescue
and many conventional rotary and chain saw applications.
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 roofing nails, joist hangers, nailing plates, flashing, light gauge sheet metal and
some lightweight concretes. It is capable of cutting automotive sheet metal, automotive glass, hurricane glass, bulletproof glass,
plastics, fiberglass, and many other composite materials. It can also cut aircraft skin, cockpit and aircraft windows, including some
aircraft structural materials*.
There are, of course, limitations but your CUTTERS EDGE FIRE RESCUE SAW with BULLET
®
CHAIN will cut a wide variety of materials
under the most severe fire ground and rescue scene conditions.
This manual will familiarize you with your new Fire Rescue Saw and take you through the proper procedures for installing the guide bar
and BULLET
®
CHAIN and Guard/Depth Gauge
®.
It will also show you how to clean and maintain the saw after use.
Before attempting to assemble or use your saw, we strongly suggest that you read this manual completely. Then carefully follow the
instructions in this manual as you proceed to prepare your Cutters Edge Fire Rescue Saw for use.
* When materials other than wood are cut, increased wear and damage should be anticipated. The possibility of chain breakage also increases.
All materials listed have been successfully cut under controlled conditions or during actual fireground and rescue incidents. However, quantity,
composition of specific materials, operator experience, existing conditions and unknown factors can adversely affect the outcome.
Beware of Kickback !
There are two types of kickback that can be encountered with the improper use of a chainsaw.
ROTATIONAL KICKBACK is the violent reaction which occurs when the chain at the upper section of the nose is
suddenly stopped, thereby dangerously driving the bar nose in an upward arc toward the operator.
LINEAR KICKBACK is a push reaction, which can occur when the saw is buried in the cut and the cut closes,
pinching the chain along the top rails of the bar, pushing the saw into the operator.
CUTTERS EDGE FIRE RESCUE SAWS WITH BULLET®CHAINS HAVE THE LOWEST KICKBACK POTENTIAL AND HIGHEST
LEVEL OF SAFETY AVAILABLE.
The Cutters Edge Fire Rescue Saw, equipped with the BULLET®CHAIN was tested for kickback by SMP, The Swedish Testing
Institute. Because of the unique cutting action of the BULLET®CHAIN, the test results on the CUTTERS EDGE FIRE RESCUE SAW
showed it to have extremely low kickback, in fact, the lowest kickback potential of any chainsaw style saw.
WARNING!

The 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®CHAIN so a scabbard is not included on these models.

5/CUTTERS EDGE FIRE RESCUE SAWS
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 actuate the inertia chain
brake (same principle as a car
seatbelt) or drive the chain brake
handle back into the operator’s hand,
engaging the chain brake and
stopping the movement of the chain.
The chain brake has three
positions:
Fig. 1. Center- operating position,
chain brake disengaged.
(Normal cutting position).
During operation, the brake is in the
neutral or center position (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 forward position
(Fig. 2). In this position the chain will
not turn.
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 into 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 operating
position. (See Fig. 1)

OF THE GUIDE BAR AND CHAIN
REMOVE CLUTCH COVER
Using the scrench tool loosen the two clutch cover

Remove Chain and Guide Bar from the saw.
TO REINSTALL CHAIN AND GUIDE BAR
To mount the guide bar, slide the guide bar onto
the two bar mount studs. See Fig. 5.
To install the chain, align the chain so that the
cutters are pointing toward the tip of the guide bar
as they lay on the top of the bar. Slip the chain onto
the clutch sprocket rim (Fig. 5). Then slip the chain
into the groove of the guide bar, again verifying that
the top cutters point toward the tip of the guide bar.
Pull the chain around the bar to be sure the drive
links are properly seated in the drive sprocket.
Mount Clutch Cover onto the two bar mount studs
(Fig.5) Using the scrench tool, turn the tensioning
adjustment screw to align the chain adjuster pin
with the hole in the guide bar. (Figs. 6 and 7).
When the adjuster pin is aligned with the hole in
the guide bar push the clutch cover to set it fully
against the saw. Install the two bar nuts finger tight.
CUTTERS EDGE FIRE RESCUE SAWS/6

7/CUTTERS EDGE FIRE RESCUE SAWS
ADJUSTING THE CHAIN TENSION
Wearing gloves or using a rag to protect your
hand, pull up on the tip of the guide bar. While
holding up the guide bar tip, tighten the chain
tension adjustment screw (Fig. 6 on page 6) by
turning it clockwise. While still holding up the bar
tip, tighten the two clutch cover nuts (Fig. 8).
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 guide bar when cutting
pressure is applied at the bottom of the bar.
Any such upward movement of the bar could
cause the chain to loosen.
Proper chain tension is a key factor in reducing
carbide breakage and increasing guide bar life.
Proper chain tension has the chain as tight
as possible without restricting chain
movement. (Fig. 8)
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 (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, (Fig.8) there is no
“sag”. (Fig. 9).
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 the point of the drive link is “just clearing
the rail” (Fig. 10) and snaps back into place when
you release it.

is at proper tension

down, drive links just clearing the rail
Fig. 9 “Sag” chain is too loose

FILLING THE TANKS
Lay the saw on its side and remove the fuel tank
cap (Fig. 11). Fill with a fresh mixture of high
octane leaded or unleaded gasoline and Cutters
Edge Synthetic 2-Cycle Oil or a high quality two-
cycle oil. Replace the fuel cap.
IMPORTANT!
• Fuel/Oil Mix ratio using Cutters
Edge Oil ... 100:1
• Using synthetic oils mix ... follow oil
manufacturers recommendation
• Using any petroleum based oil ... 50:1.
Next, remove the bar and chain oil tank cap
(Fig. 11) and fill the tank with bar and chain oil.
Replace the cap.
You do not need special detergent oils; as the
chain reaches high enough temperatures to
prevent the buildup of tars on the chain. 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
applications, with high flow properties for use,
even in extreme cold temperatures. This anti-
rust, anti-wear formula is recommended for use
on all Fire Rescue saws and on conventional
chainsaws.
Fig. 11. Fuel Cap and Oil Cap
WARNING!
IF POSSIBLE AVOID USING
GASOHOL OR ALCOHOL
BLENDED FUELS
Fuel Cap
Oil Cap
Please note that each time you
fill up or top off the fuel tank,
always top off the bar and chain
oil tank. The fuel tank and the
bar and chain oil tank are sized
so that the saw will always run out of fuel
before it runs out of bar and chain oil,
eliminating the possibility of running the
chain without proper lubrication.
WARNING!
Do not mix the bar and chain
oil with diesel fuel, kerosene or
any solvents as this actually
reduces its lubricating
properties, increases its flash
point and does not reduce
tar buildup on the chain.
WARNING!
CUTTERS EDGE FIRE RESCUE SAWS/8

THE MOMENTARY CONTACT SWITCH
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 12). To stop the
saw, push and hold the momentary contact switch
to the right. This kills the saw. When released, the
switch will snap back into the “on” position
automatically.
STARTING THE SAW
IMPORTANT!
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.
To start the saw, place it on the ground. Grip the
top handle firmly and step on the outer edge of the
back handle. (Fig.13)
IMPORTANT! CHECK THE CHAIN
BRAKE BEFORE STARTING
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 Fig. 3 on page 5).
COLD START
(1) Pull out the choke knob*. This automatically
locks the throttle trigger and the carburetor into
their optimum positions for starting. If you do
not touch the throttle during starting, there is
no possibility of flooding.
(2) Grasp the starter handle and pull sharply
upward a few times until the engine catches.
(3) Push the choke in.
(4) Pull the starter handle again.
The engine will start.
(5) Let saw run at fast idle for 5 seconds.
(6) Quickly squeeze and release the throttle
trigger to set the idle.
* We recommend storing the saw with the
choke knob pulled out.

Fig. 13. Proper starting position
9/CUTTERS EDGE FIRE RESCUE SAWS

WARM START
(Engine still warm from previous use)
(1) Pull starter handle until saw starts.
NOTE
You must depress the safety lock on top of the
handle (Figs. 14 & 15) to be able to engage the
trigger. The trigger will not function without
depressing the safety lock.
RUNNING-IN THE CHAIN
Running-in the chain stretches and fully lubricates
the chain for optimum longevity and performance.
Start the saw and run it at 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 the chain
now sags from the bar. (Fig. 16) Before readjusting,
allow the chain to cool down for three to five
minutes, or until it is cool enough to touch.
Once it is cool enough to handle, readjust the
chain to the proper tension. See Page 7 for
chain tension adjustment.
NOTE
We recommend you repeat this entire chain
running-in procedure at least once more.

CUTTERS EDGE FIRE RESCUE SAWS/10

BREAKING IN THE ENGINE
IMPORTANT: OIL TANK MUST BE FULL
Although 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
the bar and chain oil tank filled. Also, be sure the chain
brake remains disengaged throughout this 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 3/4 throttle periodically during this procedure to clear
out unburned fuel.
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.
NOTE
Cutting clean wood; plywood, trees, etc. (no nails or roofing
material) during the chain stretching procedure and/ or
engine break in procedure will decrease the required time and
result in a more complete break in. If you do cut clean wood
during these procedures make sure you do not exceed
3/4 throttle (75% maximum engine speed).
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.
WARNING!
During break-in do not run
the engine at full throttle for
more than 2 seconds or
engine damage may occur.

has been designed, engineered and carefully tested to
provide increased safety and efficiency in firefighting
and rescue applications.
In its fully extended position, the Guard/Depth Gauge
completely covers the guide bar and cutting chain,
protecting the operator from accidental contact with
the chain. Even when retracted and set for specific
depths of cut, the Guard/Depth Gauge covers all but
the chain exposed for cutting.
The Guard/Depth Gauge allows you to set a specific
depth of cut to prevent cutting any deeper than is
absolutely necessary. This prevents possible

weakening of the roof structure and prevents
exposure to hidden hazards like electrical
wiring and pipes.
These Guard/Depth Gauge features are
designed to provide the operator with
increased confidence resulting in faster cuts
with less worry. The operator can concentrate
more on cutting position, fire behavior and
the surrounding fire rescue environment.
Of course, as with any tool, it is only as safe
as its operator. You must be careful to take all
necessary safety precautions and to follow all
safe operating procedures.
These instructions are intended to help you
install and safely utilize the Cutters Edge
Tool-Less Guard/Depth Gauge®, whether you
are installing it on a new Cutters Edge Saw or
upgrading an older Cutters Edge Saw.
Take the time to read these instructions
carefully. Familiarize yourself with the parts
and components of the Tool-Less

Operation of the Tool-Less
Guard/Depth Gauge®
(Fig. 21) To adjust the Guard/Depth Gauge, if the saw
is running, first set the saw’s chain brake. Loosen the
adjusting knob and slide the outer section to the desired
setting. Retighten the adjusting knob and release the
chain brake.
IMPORTANT: In its fully extended
position, the Guard/Depth Gauge completely covers the
cutting chain. Thus, you can now start the saw on
the ground and carry it up to the roof or to your cutting
position while it is running.
This eliminates the need to restart the saw after you are in
position and assures a warmed up, operational saw.
Cutting Deeper than the Guard/
Depth Gauge®Setting
Even with the Guard/Depth Gauge set to a pre-determined
depth you can increase the depth of your cut without
changing the setting by increasing the angle of the saw in
relation to the roof surface. While cutting at the standard
45º angle (Fig. 22), the saw will cut to the depth indicated on
the depth of cut scale. But by raising the angle of the saw
to 90º (Fig. 23), you can cut up to .414 inch (10.5mm)
deeper for every one inch (25.4mm) indicated on the
depth of cut scale.
Removing the Tooless Guard Depth Gauge
(1) Remove the adjustment knob.
(2) Pull off the outer section. (Safety pin will
release as you pull outer section off)
(3) Remove the inner section by pulling up from the
locking key. (Fig 18 - See page 13)
Cleaning the Guard/Depth Gauge
It is important that the Guard/Depth Gauge be cleaned
and inspected after each use. To clean the Guard/Depth
Gauge, simply remove it, wipe off all inner and outer
surfaces and reinstall on the saw. Cleaning may also
be done with solvent in a parts washer.

Part Two:
MAINTENANCE
After each use, your Cutters Edge Fire Rescue Saw
should be cleaned and inspected. We recommend
you develop a departmental standard operation
procedure (SOP) for periodic inspection, testing and
maintenance of your Fire Rescue Saw.
CLEANING
Remove the clutch cover. Inspect it and clean all
foreign matter and debris from it (Fig. 24).
THE CHAIN
Remove the chain and inspect it closely. (Fig. 25)
THE BULLET®CHAIN COMPONENTS (Fig. 26)
Note: The BULLET®CHAIN is designed to allow
chips of carbide to break away under normal use.
If six or more cutters have 50% or more of the
carbide missing you should have the chain
repaired and sharpened. Do not judge the usability
of the BULLET®CHAIN on visual appearance alone.
The only true determination should be made on
how it cuts. If you are in doubt, make a test cut to
determine the chain’s performance.
Failure to clean the saw after
each use can lead to a loss of
performance, engine failure and
premature wear.

THE GUIDE BAR
Remove the guide bar and wipe debris from it.
Clean out the chain groove using a bar cleaning tool
or a putty knife (Fig. 27). If there is excess tar or
debris buildup on the bar, clean it off with solvent.
It is also important to thoroughly clean the oil holes
on both sides of the guide bar. (Fig. 28 )
After cleaning the bar, lubricate the bearings in the
sprocketnose (Fig. 29) with the grease and grease
gun provided with each saw.
When you reinstall the guide bar, flip the guide bar
over so the edge that was on the bottom is now on
the top. This allows even wear to the guide bar rails.

WARNING!
THE POWER HEAD
Inspect and clean the power head. (Fig. 31)
Wipe all debris and foreign matter from the power
head, making sure to clean carefully around the
clutch.
Make sure the oil slot on the power head is clear and
open. Use a bar cleaning tool or a small screwdriver
to remove any debris from this slot. (Fig. 32)
THE AIR FILTERS
Remove the foam pre-wrap air filter from the
saw (Fig. 33). Wash the pre-wrap with soapy
water, rinse with clean water and squeeze dry.
The main filter element is coated at the factory and
needs no oiling prior to its first use. The main filter
element needs to be cleaned only if there is
substantial buildup of debris. To remove the main
filter, loosen the filter clamp with a screwdriver or the
scrench tool. (Fig. 34)
Note: Pull out the choke to close the butterfly
before removing the main filter. This will prevent
foreign objects from entering the carburetor after
you have removed the filter.
Clean the main filter element with soap and water,
rinse with clean water and allow to thoroughly dry. It
is important that the main filter element is thoroughly
dry. When dry, recoat main filter element with the
filter oil provided with the saw. Spray filter oil only
around the exterior of the filter. Do not spray oil inside
the filter element.
IMPORTANT! It may take up an to hour for
the main filter element to thoroughly dry, depending
on the weather. NOTE: It is a good
idea to have a spare filter. Drying time can be over
an hour and the extra filter can get your saw
back in service faster.

CLEANING THE COOLING FINS
ON THE CYLINDER
Remove the carburetor compartment cover by first
opening the two carburetor compartment latches
(1 & 2) and remove the top of the compartment that
includes the main filter. Next, loosen the two
screws; A & B. Then loosen the one cylinder head
cover screw, C. (Fig. 35)
Remove the cylinder head cover. Check the cooling
fins (Fig. 36) for excess buildup of tar and debris. If
necessary, scrape clean or clean with a solvent.
REASSEMBLY
When you have completed all maintenance
procedures, reassemble the saw paying attention
to flip the guide bar over before you reassemble
the saw.
Flip the guide bar each time you reassemble the
saw. This provides even wear on the guide bar.
Reference the logo position each time the bar is
flipped (Fig. 30 - See page 16).
For specific engine adjustments and settings,
consult the accompanying chainsaw operations
manual.
FINAL MAINTENANCE CHECK
When the maintenance and cleaning is completed
check to make sure all nuts and screws are properly
retightened. Start and run the saw briefly.
Shut off and store for its next use.
The heat exchanging action of the
cooling fins is critical to cooling the
engine. If the fins are coated with
tar or blocked by debris over heating
and engine damage can occur!
