Welcome
Welcome
Thank you for purchasing Hurco’s Ripcord Ventilator / Stringer. The Ripcord has been part of Hurco’s
product line since the early 1980’s. The Ripcord was invented to offer a quick and efficient way to get
a tagline through a sewer line to retrieve cables for sewer cameras and pipe re-rounding equipment.
As this product evolved, it was discovered that it made a very efficient sewer manhole ventilator. The
Ripcord actually removes dangerous gases from the manhole rather than diluting them! This method of
“cross-ventilation” creates a safe, comfortable and unobstructed workspace.
Ripcord will:
• Pull a String-line 400 feet in approximately 15 seconds.
• Powerful enough to pull a deflection testing mandrel through a sewer pipe in 17 seconds
• Creates a safe work place in seconds.
• Solid Cast Aluminum impeller for maximum performance. Tested in accordance with AMCA (Air
Movement and Control Association) standards.
Hurco Technologies, Inc. would like to take this opportunity to welcome you as a new customer and
user of the Ripcord Ventilator/Stinger. You have just purchased the best ventilation and line stringing
system available. The Ripcord is simple to use and will provide you with years of service.
This manual will take you through the step by step procedures for using the Ripcord. We use simple
to understand instructions and photos to assist you in learning how to get the best results from your
Ripcord. Please follow each step completely to insure maximum performance from your Ripcord.
Your Ripcord will give you many years of service if you take care of it as you would any expensive piece
of equipment. The Ripcord is rugged and built to last. It will withstand the demands of your jobsite;
however, is not abuse proof! Be sure to assign the use of your Ripcord to a competent worker who will
take care of it.
In this manual, we will be giving you suggestions on basic line stringing and ventilation activities. As a
general rule, these suggestions are based on testing that was done on the Ripcord and OSHA’s 1910.146
confined space regulation. It will be your responsibility to read and understand this OSHA regulation and
to always use safe manhole entry procedures. Hurco Technologies, Inc. will not be responsible for the
incorrect use of the Ripcord or for the failure to follow safe manhole procedures. Assign a competent
worker with knowledge on proper confined space procedures. You can find a copy of the OSHA
regulations on the OSHA website at http://www.osha.gov or do a Google search on “OSHA 1910.146”. To
watch a video on safe confined space ventilation, go to Hurco’s website at www.gethurco.com.
WARNING: The Ripcord is not explosion proof. Do not start the Ripcord in the presence of volatile gases.

Important Safety Information
WARNING!
READ ALL OPERATING MANUALS
BEFORE OPERATION OF EQUIPMENT
GENERAL SAFETY INFORMATION
Machine Operation
• Always wear protective clothing and safety glasses when operating machinery.
• Never service or repair the Ripcord while running. Allow engine to cool.
• Whenever fueling the Ripcord, shut off engine and do not smoke.
• Periodically inspect system components. Perform routine maintenance as required.
• Do not operate a gasoline engine in an enclosed area. Be sure the area is well ventilated.
SAFETY FIRST!
Simply opening manholes to air them out will not insure a safe work environment. ALWAYS ventilate and test your work area
before entering any confined space. Refer to these NIOSH recommendations for confined space entry:
• Always test confined spaces for oxygen content and the presence of toxic or flammable gases or vapors before entry.
This would mean an oxygen supply of at least 19.5%, flammable range less than 10% of the lower explosive limit, and
an absence of toxic air pollutants.
• Test the air quality of the confined space. Ventilate with the proper ventilation equipment, and then test again before
entry.
• No one should ever enter a confined space without an observer posted outside with the appropriate rescue
equipment (safety belt/harness, lifeline, respirators, etc.).
• Contractors should also ensure that all subcontractors they employ have a safety program which addresses the
hazards to which they will be exposed. All employees at the worksite should be trained.
For more information concerning confined space entry, go to the Center for Disease Control / NIOSH at
http://www.cdc.gov/NIOSH/ then type “confined space” in the search box.

Operating Instructions
Ripcord for Cross Ventilation
Setting up your Ripcord for Cross Ventilation will draw
dangerous gases away from your work space. This method
of ventilation will help create a safe and unobstructed work
space. However, before you ever enter a confined space,
such as a manhole, you must follow safe confined space
entry techniques. Refer to OSHA’s 1910.146 regulation and
never enter a manhole until it has been thoroughly tested
using high quality, calibrated gas detection equipment.
Always keep a gas monitor with you at all times. The
environment in a manhole can change rapidly.
Testing the Manhole for Dangerous
Gases
There are many gases that can be found in a manhole, and
the type and quantity of gases will vary greatly from one
area to another. Gases cannot be properly ventilated in a
confined space by simply opening manhole covers. You
must use forced air ventilation whenever you work in a
manhole.
Three of the most common gases found in a manhole are
Hydrogen Sulfide (heavier than air), Methane (lighter than
air) and Carbon Monoxide (same weight as air). However, the
lack of oxygen in a manhole is the number one killer. Never
trust your sense of smell to determine if a manhole is safe.
Some of the most dangerous gases will not have an odor.
Follow these steps:
1. Read and understand the OSHA 1910.146 regulation.
2. Use a high quality and calibrated gas detection
instrument to test the manhole prior to entry.
a. Test the top area of the manhole for lighter than air
gases.
b. Test the middle area of the manhole for gases that
are the same weight as air.
c. Test the bottom area of the manhole for gases that
are heavier than air.
3. Always keep a properly working and calibrated gas
monitor with you at all times.
4. Have a properly trained person watching you at all
times.
5. Use a certified and man-rated tripod when entering or
leaving a manhole.
6. Use continuous ventilation when working in the
manhole.
It is important to understand that ventilation times will vary
depending on the type of gases that are in the manhole.
Some gases, like hydrogen sulfide, are heavier than air and
will take longer to ventilate. Give the Ripcord ventilator
plenty of time to ventilate the manhole, and then re-test it
for gases. Other causes for additional ventilation time can
4
be due to variations in atmospheric conditions, plugged
or partially plugged pipelines, and manhole depths and
diameters.
When you are using the Ripcord set up in the cross
ventilation configuration, never allow a worker in the same
manhole where the Ripcord is located. Doing so can cause
serious harm or even death.
In areas where controlling the gases in a manhole are
difficult, two Ripcords can be used; one on the uphill
manhole and one on the downhill manhole, with the worker
entering the middle manhole.
Setting up the Ripcord for Cross
Ventilation
1. Read all warnings displayed on the Ripcord before
operation!
2. Check oil and gas before starting Ripcord.
3. Place Ripcord on first manhole above or below the
manhole to be worked in. You cannot skip a manhole
between the worker and the Ripcord. Only the
manhole to be worked in and the manhole where the
Ripcord is located should be open. All other manholes
in the vicinity of the work manhole should be kept
closed.
4. Start the Ripcord and operate at full throttle.
Note: It should not be necessary to block pipes entering
either the manhole where the Ripcord is located or the
manhole where the worker is located. However, because
every manhole configuration can be different, never trust
your senses. Always test the manhole prior to entry and
continually monitor the manhole while working in it. If it
is determined that you cannot control the gases migrating
into the manhole, blocking or partially blocking incoming
pipes may be necessary.
As the Ripcord pulls dangerous gases away from the work
manhole, it pulls in fresh air. This air enters the manhole at a
very high pressure and will actually create an “air dam” effect,
holding back gases from migrating in to the work manhole.
This affect is similar to the air curtains often found in super
market entry ways. These air curtains allow the store to
keep their doors open while keeping the temperature in the
store constant and holding out the cold or warm outdoor
air. That blast of air you feel when you enter the store is the
air curtain. It should be noted, however, that there can be
situations where this effect may not work. Always use your
gas monitors to determine if the area in the manhole is safe.

Operating Instructions
Ripcord for Blow-In Ventilation
When cross ventilation is impossible, you can use the
Ripcord with an optional blow-in ventilation kit. Setting up
your Ripcord for blow-in ventilation will dilute dangerous
gases in your work space. This method of ventilation
will help create a safe work space but will require more
ventilation time. However, before you ever enter a confined
space, such as a manhole, you must follow safe confined
space entry techniques. Refer to OSHA’s 1910.146 regulation
and never enter a manhole until it has been thoroughly
tested using high quality, calibrated gas detection
equipment. Always keep a gas monitor with you at all times.
The environment in a manhole can change rapidly.

plenty of time to ventilate the manhole, and then re-test it for
gases. Other causes for additional ventilation time can be due
to variations in atmospheric conditions, plugged or partially
plugged pipelines and manhole depths and diameters.
When you are using the Ripcord set up in the blow-in
ventilation configuration, the hose must be dropped to within
6
one (1) foot of the bottom of the manhole. This is the only
possible way to dilute heavier than air gases. Not following
this procedure can cause serious harm or even death.
Setting up the Ripcord for Blow-In Ventilation
1. Read all warnings displayed on the Ripcord before
operation!
2. Check oil and gas before starting Ripcord.
3. Install the optional Blow-In Ventilation Kit on to the
Ripcord (see page 9). Set Ripcord on stand that is
included with the Blow-In Ventilation Kit and attach
the flexible ducting.
4. Drop flexible ducting to within one (1) foot of the
bottom of the manhole.
5. Start the Ripcord and operate at full throttle.
Note: Blow-in ventilation will vary in the time it takes to
dilute the gases in the workspace to a safe level. These times
can be from a few short minutes to several minutes. Never
assume that the workspace is safe just because the Ripcord
is blowing air into the manhole. You must test the manhole
prior to entry. Remember, you are adding oxygen to the
manhole and potentially making some gases more volatile.
Allow plenty of time to ventilate the workspace and follow
the instructions for testing the manhole for dangerous gases
and oxygen content.
Remember that the ventilation duct must be within one (1)
foot of the bottom of the manhole. Always use your gas
monitor to determine if the area in the manhole is safe.

Ripcord for Stringing a Pipeline
Using the Ripcord for pulling a rope through a pipeline is
quick and easy. You can also use the Ripcord to pull Hurco’s
Whistle Gauge through a pipe in about 17 seconds! You
should not have to enter a manhole to do pipe stringing
or deflection testing; however, if you do need to enter
the manhole, you must follow safe confined space entry
techniques. Refer to OSHA’s 1910.146 regulation and never
enter a manhole until it has been thoroughly tested using
high quality, calibrated gas detection equipment. Always
keep a gas monitor with you at all times. The environment in
a manhole can change rapidly.

you can actually ventilate the manhole prior to stringing.
But again, if you must enter the manhole, you are required
to follow safe manhole entry techniques. Refer to the OSHA
1910.146 regulation. Not following this procedure can cause
serious harm or even death.
Setting up the Ripcord for stringing a
pipeline
1. Read all warnings displayed on the Ripcord before
operation!
2. Check oil and gas before starting Ripcord.
3. Install the Ripcord on a manhole adjacent to the
manhole you are stringing from. You cannot skip
manholes.
4. Start the Ripcord and operate at full throttle.
5. Lower the parachute into the manhole close to the
pipe you are drawing air through. The suction will
inflate the parachute and it will take off down the line.
6. Once the parachute has reached the manhole where
the Ripcord is, turn Ripcord off, remove from manhole
and use a rope with a hook on the end to retrieve the
parachute and string.
Note: The time it takes to pull a string through a pipeline can
vary on a number of conditions. The number of laterals, the
size of the pipe, the size of the adjacent pipes and the size of
the manhole can all have an effect on how quickly the string
travels through the pipe. In rare cases, it may be necessary
to plug or partially plug the adjacent pipes coming into the
manhole where the Ripcord is.
Hurco offers a full line of rope reels and parachutes for your
pipeline stringing activities.
It is important to understand that ventilation times will vary
depending on the type of gases that are in the manhole.
Some gases, such as hydrogen sulfide, are heavier than air
and will take longer to ventilate. Give the Ripcord ventilator
plenty of time to ventilate the manhole, and then re-test it

Follow these steps to remove an impeller:
1. Drain all gas and oil from the Ripcord.
2. Turn Ripcord upside down and remove the expanded
metal guard.
3. Remove the center bolt from the impeller.
4. Remove the three securing bolts from the taper lock
bushing.
5. Reinstall two of the bolts into the threaded holes in
the taper lock bushing.
6. Slowly and evenly tighten bolts until taper lock
bushing separates from the impeller.
7. Remove Impeller and taper lock bushing.
Note: The Ripcord impeller was installed using Loc-Tite
609 adhesive. It may be necessary to warm the taper lock
bushing to help release this adhesive. Do not apply too
much heat.
the impeller. DO NOT USE AN IMPACT WRENCH! All
tightening must be done by hand. Special bolts were
shipped with your impeller. Do not attempt to use
bolts other than those supplied because they could
cause damage to the impeller. Damage caused during
installation is not covered under warranty.
7. Do not use torque instructions on the box provided
with the taper lock bushing. These instructions are
for installing a cast iron pulley on an engine shaft.
This is too much torque for the Ripcord impeller.
Recommended torque for the taper lock bushing
when used with the Ripcord impeller is 10 ft lbs of
torque. This is a situation where tighter is not better.
Over tightening of the taper lock bushing will break
the impeller which is not covered under warranty.
8. CAUTION: Do not attempt to tighten the collar of
the taper lock bushing tight against the impeller. This
will break the impeller which is not covered under
warranty. There should be about 1/8” to 1/4” space
between the collar of the taper lock bushing and the
impeller when installed correctly.
9. Install center washers into the taper lock bushing to
fill gap from the end of the engine shaft to the face of
the taper lock bushing. Install center bolt. Remember,
you must use the Loc-Tite 609 adhesive on all contact
surfaces and on all bolts.
10. Install protective expanded metal screen.
Follow these steps to install an impeller:
1. Make sure engine shaft is clean and the bore on the
taper lock bushing is clean. Using a quality brake parts
cleaner will make this much easier. Remove any burrs
or nicks from all metal parts.
11. Let Ripcord sit for 24 hours before using to allow the
Loc-Tite 609 to cure.
12. Put oil and gas in engine.
2. Align holes of taper lock bushing with the threaded
holes in the impeller. The taper lock bushing is
tapered and must align into the impeller so the taper
in the impeller matches the taper of the taper lock
bushing.
3. Be sure to align the keyway on the motor shaft with
the black line on the impeller. This black line is a
balance mark and it is critical to have it in line with the
keyway to prevent vibration.
4. Use Loc-Tite 609 on engine shaft, the inside and
outside of the taper lock bushing and on all bolts.
Loc-Tite 609 is the only acceptable adhesive. Using
another adhesive may cause a failure of the impeller.
5. When the impeller and bushing are properly
placed on the engine shaft, the shaft should be
approximately 1/8” to 1/4” inside the bushing. You
can use a thick piece of cardboard as a gauge on the
distance to hold the impeller away from the engine
mounting support brackets.
6. Gradually and evenly tighten the three taper lock
bushing bolts by turning 1/4 turn at a time and
rotating to the next bolt. Note: The taper lock
bushing must be installed evenly or it could damage
