WARNING
Some dust created by power sanding, sawing, grinding, drilling, and
other construction activities contains chemicals known to the State of
California to cause cancer, birth defects or other reproductive harm.
Some examples of these chemicals are:
• Lead from lead-based paints,
• Crystalline silica from bricks and cement and other masonry products,
and
• Arsenic and chromium from chemically treated lumber.
Your risk from these exposures varies, depending on how often you do
this type of work. To reduce your exposure to these chemicals: work in a
well ventilated area, and work with approved safety equipment, such as
those dust masks that are specially designed to filter out microscopic
particles.

INTRODUCTION
DANGER
• This system is designed for use with a
special bar and chain for fire department
application. This system should not be used
for conventional wood cutting applications.
• Review ECHO Safety Chain Saw Manual and
note exceptions as listed below.
• If the unit is modified for conventional wood
cutting operations, read rules for safe
operation and instructions carefully in the
corresponding CS-8000 TYPE1-E ECHO
Chain Saw Instruction Manual and the
ECHO Chain Saw Safety Manual. Use only
the guide bar and chain combinations listed
in the instruction manual with a Kick Guard
installed on the guide bar. A free copy of
the Chain Saw Safety Manual can be
obtained from your ECHO dealer or by
writing ECHO, INCORPORATED, 400
Oakwood Road, Lake Zurich, IL 60047-1564.

SAFETY
Read and understand the ECHO
chain saw safety manual before
using this saw
The Safety Manual available for your QuikVent™
system and this Instruction Manual, covers
terminology, safety features, practices and forces
at work during cutting.

SAFETY
Part Number 890191-32632
WARNING!!!
This system is capable of severe kickback that could result in serious
injury. Read and follow all safety precautions in the instruction and
safety manuals. Failure to follow instructions could result in serious
personal injury.
For Quickvent System: This system is designed for use with a special
bar and chain for fire department applications. The QV bar and chain
should not be used for conventional wood cutting applications. Do not
operate the system unless you have specialized training in its use for
dangerous and hazardous operations. Full fire department turnouts are
required when using this system.
For Chain Saw (Woodcutting): Do not operate this chain saw unless you
have extra ordinary cutting needs and experience and specialized
training for dealing with kickback. ECHO chain saw with significantly
reduced kickback potential are available.
TO AVOID KICKBACK
1) Hold the chain saw firmly with both hands,
2) Tip contact is required (for QuickVent applications only) to complete
boring operations. Be aware that kockback could occur.
Part Number 890191-32632
Follow IFSTA practices Follow safe and effective practices developed by
The International Fire Service Training Association
(lFSTA) for transport, venting and all other fire
fighting techniques.
Follow safety decals Locate the safety decals on your QuikVent™
system. Make sure the decals are legible and that
you understand them and follow them.
WARNING
Chain brake must be unlocked before removing or installing clutch
cover. Improper cover installation can result in serious injury and
cause severe damage to saw.
El freno de la cadena debe ser bloqueado antes de remover o de instalar
la cubierta del embrague. La instalación incorrecta de la cubierta

Avoid carbon monoxide
CAUTION
DO NOT operate system in a confined area.
SAFETY
Follow all maintenance procedures
Handle fuel safely
DANGER
ALWAYS store gasoline in an approved
container.
DO NOT smoke while handling gasoline.
ALWAYS stop the engine before refueling.
DO NOT refuel a hot engine. Wait until it
cools.
ALWAYS remove the fuel cap slowly in order
to relieve any pressure build-up in tank.
DO NOT overfill the tank and always clean up
spilled fuel.
After refueling tighten fuel cap firmly and
check for leakage. In case of fuel leakage
repair before starting operation since there is
a danger of fire.
ALWAYS restart the engine at least 3 m (10
feet) away from refueling point.
3 m
(10 feet)
Follow all maintenance procedures outlined in the
maintenance section of this manual to ensure that
the saw will operate safely and will start and
operate when needed.
Wear protective clothing and
equipment
Wear full turn-out gear in accordance with your fire
department’s regulations.

5QV-8000 TYPE1-E
Avoid kickback
DANGER
KICKBACK may occur when the nose or tip
of the guide bar touches an object, or when
the material being cut 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 saw chain along the top of the
guide bar may push the guide bar rapidly
back towards the operator. Either of these
reactions could result in serious personal
injury by causing you to lose control of the
system. Do not rely exclusively upon the
safety devices built into your saw. As a chain
saw user, you should take several steps to
keep your cutting jobs free from accident or
injury.
SAFETY
Keep a safe distance from co-
workers
Make sure there is another person nearby when
operating the system, but also make sure they are
at a safe distance.
Clear work area Make sure that hazardous debris such as glass or
wire is cleared from the area to be ventilated.
Operate safely AVOID operating the system when you are fatigued.
ALWAYS remains alert when operating the system
to avoid possible injury to yourself and others.
DO NOT operate the system while under the
influence of alcohol or drugs.

QV-8000 TYPE1-E
Use correct technique
SAFETY
DANGER
Grasp both handles firmly and bring the saw
to full throttle. Using a steady pressure, rock
the tip of the saw into the roof surface, using
the skid plate as a pivot point between the
system and the roof. Keeping the weight of
the system against the roof with a firm grip
will increase operator comfort and control
during this dangerous operation.
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 of the saw with both
hands, the right hand on the rear handle, and
the left hand on the front handle. When the
engine is running, use a firm grip with thumbs
and fingers encircling the chain saw handles. A
firm grip will help you reduce kickback and
maintain control of the saw. Do not let go.
3. Always work upwind.
4. Cut at high engine speeds.
5. Ventilation and breaching use “plunge cutting”
which entails boring into a structure. There is
always a chance of kickback even when the
plunge cut is expertly done.
6. Keep the skid plate touching the cutting
surface.
7. Avoid cutting joists.
8. Do not overreach or cut above shoulder height.
9. Follow manufacturer’s sharpening and
maintenance instructions for the saw chain.
10. Use only replacement bars and chains
specified by ECHO, Inc.

Safe operation tips
(Ventilation Procedures)
DANGER
BORING -Ventilation and breaching uses
“plunge cutting” which entails boring into a
structure. There is always a chance of
kickback even when the plunge cut is
expertly done. Keep the skid plate touching
the surface. Grasp both handles firmly and
bring the saw to full throttle. Using a steady
pressure, rock the tip of the saw into the
surface using the skid plate as a pivot point
between the system and the surface. Keeping
the weight of the system against the surface
with a firm grip will increase operator
comfort and control during this dangerous
operation.
CUTTING - After penetration, follow the
contour of the skid plate until the bar has
reached the approximate angle illustrated at
the right. Position the skid plate on the flat
surface, maintaining full throttle and steady
pressure while keeping the saw on the
surface. Pull the saw back, ripping through
the surface. Avoid cutting through joists and
rafters.
1. Follow all fire department procedures on safe
ventilation techniques and on avoidance of
cutting near gas and electric services.
2. Keep both hands on handles when engine is
running.
3. Always operate the saw at full throttle when
making a cut.
4. Always bury the tip of the cutting bar in the
cutting surface.
5. Make sure the skid plate is in contact with cutting
surface.
6. Avoid cutting above shoulder height and
overreaching.
