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.
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.
WARNING!!!
TO AVOID KICKBACK

SAFETY
Keep a safe distance from coworkers
Clear work area
Operate safely
Make sure there is another person nearby when
operating the system, but also make sure they are
at a safe distance.
Make sure that hazardous debris such as glass or
wire is cleared from the area to be ventilated.
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.
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.

QV-8000 TYPE1-E
SAFETY
Use correct technique
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.

Carburetor adjustment
(As Needed)
MAINTENANCE
Every unit is run at the factory and the carburetor is
set in compliance with Emission Regulations. In
addition, the carburetor is equipped with “H” (High
Speed) and “L” (Low Speed) needle adjustment
limiters that prevent settings outside acceptable
limits.
1. Before adjusting carburetor clean or replace air
filter and muffler “Spark Arrestor Screen”.
2. Make sure the bar and chain are properly
adjusted.
3. Start engine and run several minutes to bring to
operating temperature. Flash choke twice during
warm-up to clear any air from the fuel system.
4. Stop engine.
Turn “H” speed needle counterclockwise (CCW)
to stop.
Turn “L” speed needle midway between full
clockwise (CW) stop and CCW stop.
5. Idle Speed Adjustment:
• Start engine, turn “Idle” speed adjustment
screw CW until the saw chain begins to turn,
then turn screw out CCW until the saw chain
stops turning.
Turn screw out, CCW, an additional 1/4 turn.
6. Accelerate to full throttle for 2 - 3 seconds to
clear any excess fuel in the engine, then return
to idle.
Accelerate engine to full throttle to check for
smooth transition from idle to high speed.
If engine hesitates turn “L” needle CCW 1/8 turn
and repeat acceleration.
Continue adjustment until smooth acceleration
results.
7. Check idle speed and reset if necessary as
described in item 5. If a tachometer is available
idle speed should be set to 2800 - 3000 r/min.
WARNING
Cutting attachment must not move when unit
is idling.
CAUTION
When starting, idling adjustment speed
should be adjusted not to rotate the saw
chain. Correct idle speed is adjusted 2800 to
3000 r/min. Or 1/4 turn CCW from the point
the chain stops moving.
When you experience trouble with the
carburetor, contact your dealer.
