I. Introduction
The GB/JetLine®Blower and Blo-Vac™ Systems are
low pressure tools that deliver high volume air stream,
which is used to place pull line in most conduit from
1
⁄2” to 6” diameter.
Blow-Vac™ systems are intended for commercial
use only.
The systems are convenient to use in new and existing
construction. They require a 120V, 60Hz. grounded
power source. See Power Unit Specifications for
electrical power requirements, Tables 1 and 2.
A Line Carrier – to serve as a movable object that
supplies the pulling force to install pull line in conduit.
Pull Line – for pulling wire through the conduit, to pull
rope or cable for large or difficult runs.
A thorough understanding of all components and their
functions and operating precautions is essential for safe
and efficient use of the system.
Read and understand all the instructions before
attempting to use the system or blow line into conduit.
II. Purpose of this Manual
The Blower or Blo-Vac™ System consists of four
basic components:
The Power Unit – a high volume air or vacuum source.
Hose and Seal-Off – to channel the air into the conduit
and form a seal at the conduit entrance.

appliance basic precautions should always be followed,
including the following.
Read all Instructions before using the Blo-Vac™ System.
Do not pick up anything that is burning or smoking, such
as cigarettes, matches, or hot ashes.
When used for vacuum clean-up, do not use without filter
bag in place.
Do not leave the Blo-Vac™ when plugged in. Unplug
from outlet when not in use and before servicing.
To reduce the risk of electrical shock: Do not expose to
rain. Store indoors.
Use only as described in this manual. Use only
manufacturer’s recommended attachments.
Do not use with damaged cord or plug. If the Blo-Vac™
is not working as it should, has been dropped, damaged,
or dropped in water, return it to a service center.
Do not pull or carry by cord, use cord as a handle, close
a door on cord, or pull around sharp edges or corners.
Do not run the Blo-Vac™ over cord. Keep cord away
from heated surfaces.
Turn off switch before unplugging.
Do not use to pick up flammable or combustible liquids
such as gasoline. Do not use in areas where they
are present.
Use extra caution when working on a ladder, elevated
platforms, stairs, etc.
Do not use the power unit in a manhole — keep the
power unit above ground.
All GB/JetLine®conduit fishing Blo-Vac™ systems are
designed to force loose debris of all types out of the
conduit by means of a pressurized force. Serious or
critical injury may result to anyone struck by high velocity
debris or the line carrier. Warn all personnel to stand
clear of the conduit exit prior to pressurization
procedures or blowing line into the conduit.
Do not unplug by pulling on cord. To unplug, grasp the
plug, not the cord.
Do not handle plug or Blo-Vac™ with wet hands.
Do not put any object into openings. Do not use with any
opening blocked: keep free of dust, lint and anything that
may reduce air flow.
Keep hair, loose clothing, fingers and all parts of body
away from openings and moving parts.
GB/JetLine®Blo-Vac™ Systems have been designed
specifically for fishing conduit. The system, under certain
field conditions, may be used to remove debris or water
from the conduit. The electric motor is protected from
liquid entering the fan area by a float ball. If liquid is
discharged, the float ball has been defeated. Immediately
unplug unit from power source and check to make sure
the float ball is functioning properly and the sealing area
is free of foreign matter.
Failure to observe these instructions or misuse of
equipment could result in serious injury or possible death.

VI. Product Description
Blo-Vac™ Systems
GB/JetLine®Blowers and Blo-Vac™ systems are
designed to provide a convenient means of installing pull
line in a “sealed” conduit. “Sealed” conduit for this
purpose is considered EMT conduit with compression
type couplings, rigid conduit with threaded joints, or PVC
conduit with adhesive bonded joints.
Conduit with set screw type couplings does not
effectively seal joints and substantial air or vacuum loss
occurs making it difficult to maintain pressure or vacuum
to place a line in the conduit.
Blower Systems
GB/JetLine®supplies two blower systems; the
B45 Bak-Pak™ (for fishing from 1⁄2” through 21⁄2” trade
size conduit) and the B60 Super Blower™ for heavy duty
work in conduit from 21⁄2” through 6”. FIGS. 2 and 3.
B45 Bak-Pak™
The B45 Bak-Pak™
conduit fishing kit is
equipped with a light
weight 1261 (Fig. 2)
Power Unit, three foot
hose, shoulder strap,
power saver line
packages, foam line
carriers, inflatables and
accessories for fishing
conduit from 1⁄2” through
21⁄2”. Bulk pull line is not
included with the kit.
B60 Super Blower™
The B60 Super Blower™
was designed for use
in long underground
single bore conduit from
21⁄2” through 6”. The
B3000 Power Unit must
remain above ground for
safety reasons, and the
21⁄2” diameter x 25 ft.
long hose and seal-off
are used in the manhole.
The portable triple motor
power unit provides a
high volume of air to
blow a line in large bore
conduit whether above
ground or below ground.

VII. Use and Operation
C. Selecting the Pull Line
The primary purpose of the GB/JetLine®Conduit Fishing
System is to place a pull line in the conduit by the
quickest and easiest means available. The GB/JetLine
®
Blower and Blo-Vac™ systems are low pressure, high
volume machines that are easy and convenient to use.
A. Blowing Line in the Conduit
The GB/JetLine®Blower and Blo-Vac™ systems are
designed to blow line in a “sealed” conduit such as EMT
conduit with compression type couplings, rigid conduit
with threaded joints, or PVC conduit with adhesive
bonded joints. These types of conduit require very
little effort to install a pull line with the Blower or
Blo-Vac™ system.
There are some conduit runs that will be difficult or
impossible to blow a line in, such as:
1. Conduit containing hard packed sand, silt, debris
or concrete.
2. Conduit containing water with a head greater
than the maximum water lift of the Blower or
Blo-Vac™ system.
It is not possible to foresee all conduit situations that may
be encountered, therefore, the following is presented as
a guide in selecting pull line. Determine which best fits
the situation; whether the line is to be used for conduit
identification, pulling in a larger line or rope, pulling in
wire or for wire pulls at a later date.
1. Identification of a conduit termination where multiple
conduit runs originate from a single location.
Recommended line: Power Saver™ Line Packages
or Bulk Nylon Line.
2. Placing a line in the conduit for use at a later date.
Recommended line: Small conduit 1⁄2”, 3⁄4” and 1” —
Power Saver™ Line Packages, Bulk Nylon Line or
PL232 Pull Line. Larger conduit 11⁄4” through 6” —
Tag-Along™ Line Packages, PL232 or PL235.
3. Pulling in larger line, rope or steel winch cable.
Recommended line: Small conduit — same as
above. Larger conduit PL232, PL235 or Poly Rope.
4. Pulling wire in conduit. Recommended line: PL232,
PL235 or Poly Rope
D. Power Saver™ Line Packages
3. Conduit with leaking or separated joints.
4. Conduit with two sizes of duct connected by
a reducer.
5. Conduit with unsealed set screw couplings.
6. Small diameter conduit of several hundred feet
with multiple bends.
Let Gravity Help
When blowing line in conduit of tall buildings or
underground duct, start at the highest elevation of the
conduit entrance. In underground duct; water may have
accumulated in low points of the run, and the blower may
not be able to force it out. Start at the highest point.
B. Preparation
It is helpful to know the purpose for which the line is to
be used once it has been blown into the conduit.This will
aid the user in selecting the appropriate line for
the job.
Knowing the approximate length of the conduit run will
prevent selecting a line too short for the run. For
example, if lightweight pull line is being placed in 3⁄4”
conduit with a estimated length of 195 to 200 feet, select
a 300 ft. Power Saver™ line package for the run. An
alternate solution would be to use a 3⁄4” foam line carrier
pulling bulk nylon line. Either selection would insure an
adequate length of line.
The Power Saver™ line package is the easiest and
most versatile line that can be installed in conduit. The
self-contained (no line carrier needed) 17 lb. breaking
strength nylon line package comes in different lengths
sized for 1⁄2”, 3⁄4” and 1” conduit. It dispenses a line as
the package is blown or vacuumed through the conduit.
The line may be used for identification of the conduit
exit, pulling in a heavier pull line (PL series pull line
or small rope).

E. Tag-Along™ Line Packages
F. PL Series Pull Line
The Tag-Along™ line package must be used with a line
carrier (foam or inflatable) in 11⁄4” or larger conduit. The
increased package diameter and length prevents the
package from passing freely through or around bends in
conduit less than 11⁄4”. Once attached to the line carrier,
the Tag-Along™ line package function and operation is
similar to that of the Power Saver™ package. Breaking
strengths are 22 lb. and 50 lb. depending on the
particular Tag-Along™ package.

JetLine®linear stranded PL series pull lines are designed
specifically for conduit fishing. These lines are made of
strong polyolefin plastic that will not rust, rot or mildew.
The coreless wound roll of knot free pull line makes
center dispensing from the carton a convenient feature
when feeding the pull line directly into the conduit
through the seal-off.

Tag-Along™ line packages perform the same function
as Power Saver™ line packages except they are used
in 11⁄4” diameter and larger conduit. Tag-Along™
package must be used with a line carrier to supply the
pulling force.
Select the Tag-Along™ line package and a line carrier
either foam or inflatable that fits the conduit diameter and
proceed as follows:
If a foam line carrier is selected—
1. Attach the Tag-Along™
line package plastic eye
to hook. Pull out
approximately two feet
of line. Tie off the ends
of the line to prevent it
from being accidentally
pulled into the conduit.
2. Insert the foam line
carrier and Tag-Along™
package in the conduit.
3. Select the seal-off that
best fits the conduit —
JV07 Dial-A-Line™ body
with the JV12 seal-off or
the B26 Dial-A-Line™
body with the BV23 or
BV24 seal-off.
4. Hold the seal-off rubber
cone firmly in the
conduit and turn on the
power unit. The run time
will be longer than that
for the Power Saver™ line package because of the
larger conduit and greater volume of air required.
However, the run time in 3” and 4” conduit
200 to 300 feet long should be complete in
10 to 15 seconds.

3. In large conduit: (4”, 5” and 6” diameter), it may be
necessary to point the seal-off nozzle at the plastic
sleeve of The Inflatable®to achieve initial inflation.
This is accomplished by tilting the seal-off in the
conduit entrance. Otherwise, the Inflatable®in its
collapsed state may allow the stream of air to blow
past it.
Blowing Pull Line in the Conduit
All GB/JetLine systems may be used to blow pull line or
nylon line in the conduit. Position Blo-Vac™ systems in a
location that allows good access to the conduit entrance.

Vacuuming Line in Conduit
with the Inflatables®
Vacuuming Dirt and Water — Each Blo-Vac™ comes
with a cloth filter bag that must be used when vacuuming
dirt and water. Use as follows:
The Blowers and Blo-Vac™ systems should require very
little maintenance. If the unit should require service, see
instructions below.
Blower overheating occurs when attempting to blow line
in blocked conduit or a duct filled with water having a
head greater than the water lift capability of the blower.
See Table 1.
The 1261 and B3000 Blowers have an automatic thermal
overload switch built into the motor. If overheating
occurs, the switch will turn the motor off. After a cooldown period of 15 to 30 minutes, the motor will
automatically re-set. The motor can be restarted.
Blo-Vac™ power units are equipped with a perforated
filter screen, located on the under side of the motor
compartment. Occasionally the screen becomes clogged
with lint and dust and it should be cleaned to maintain
maximum air flow.

1. Release the latches securing the top and center
together.
2. Remove the filter bag from the bottom tool storage
section. Slide the filter bag onto the intake canister
located on the bottom of the motor. The filter bag
prevents dust from entering the motor. Dust and dirt
will damage the motor and cause premature failure.
3. After use, clean the filter bag by shaking off the
excess dirt and store the clean bag in the lower
compartment.
4. The Blo-Vac™ is equipped with a ball float to
prevent water from entering the motor. If the ball
float seals the motor inlet, the motor will sound
different from usual. Immediately turn the unit off.
Empty the recovery section and check the inlet
screen for lint and dirt. Clean and reassemble the
Blo-Vac™ sections.
