1.0 IMPORTANT SAFETY
INSTRUCTIONS
WARNING: To avoid risk of injury:
1. Read and understand the entire owner's
manual before attempting assembly or
operation.
2. Read and understand the warnings posted on
the machine and in this manual. Failure to
comply with all of these warnings may cause
serious injury.
3. Replace warning labels if they become
obscured or removed.
4. This chain hoist is designed and intended for
use by properly trained and experienced
personnel only. If you are not familiar with the
proper and safe operation of a chain hoist, do
not use until proper training and knowledge
have been obtained.
5. Do not use this chain hoist for other than its
intended use. If used for other purposes, JET
disclaims any real or implied warranty and
holds itself harmless from any injury that may
result from that use.
6. Do not install this chain hoist where explosive
hazards may exist.
7. Give your work undivided attention. Looking
around, carrying on a conversation and “horseplay” are careless acts that can result in
serious injury.
8. Do not use to lift people, or loads over people.
Warn others in the vicinity when lifting or
transporting a load. Avoid swinging load and
hook.
9. Do not exceed the rated lift capacity of the
chain hoist.
10. Make sure limiter devices are operating
properly. Do not use limit switches as routine
operating stops; they are emergency devices
only.
11. Verify that load chain is properly seated in load
sheeve before operating hoist.
12. Do not use the load chain as a sling or wrap
load chain around the load.
13. Do not use the load chain to side-pull a load.
14. Always inspect the chain hoist for damage
prior to use. Do not use a chain hoist with
twisted, kinked, worn or otherwise damaged
chain. If the chain hoist is damaged, do not
use until it has been repaired or replaced.
15. Do not use more than one chain hoist to lift or
move a load. If this is unavoidable, each chain
hoist must have the same capacity as the load
to be moved.
16. Never allow the load chain to “set” over sharp
edges. All lifts must be made with straight
chain that is free of obstacles.
17. Do not use chain hoist unless load is centered
between top and bottom hooks.
18. Protect load chain from weld splatter and other
contaminants. Do not allow the hook or chain
to be contacted by a live welding electrode.
19. Always take time to study the job to be
performed and choose the safest method. Do
not place yourself or other people in an unsafe
position. Maintain constant awareness of the
lifting environment.
20. Leave all internal maintenance to a qualified
JET service center.
21. Disconnect hoist from power source before
performing maintenance or opening the
housing.
22. Do not leave a suspended load unattended.
23. Replace the chain with factory replacement
chain only. Do not use any other type of chain.
24. Never use the chain hoist if either hook is
stretched, deformed, or has a broken or
missing safety latch. Always replace the safety
latch and/or the hook before placing the chain
hoist back into service.
25. Keep safety guards in place at all times when
the hoist is in use.
26. Do not operate this hoist while tired or under
the influence of drugs, alcohol or any
medication.
27. This hoist is not designed for exposure to
outdoor elements.
28. Understand and follow all procedures as set

5.0 Product introduction
Your JET variable speed hoist is designed and constructed to provide consistent, long-term operation if used in
accordance with the instructions set forth in this manual.
JET BLVS series hoists are variable speed, available in 120 volt, single-phase power, and varied chain lengths.
The mechanical load brake prevents slippage up to maximum load capacity. The hoist is also provided with
overload protection and limit switches.
This hoist complies with FEM standards.
6.0 Glossary
Key terms the hoist operator should know:
Creep speed: Slow, constant, fixed rate of motion
of a hoist.
Duty cycle: The amount of work a hoist can
perform in a given period of time, generally
measured by maximum run time and number of
starts within that period. Duty cycle ratings are
designated H1 through H5.
Duty class: Identifies the type of service for which
a hoist is designed, designated A through F.
Headroom: Minimum distance between saddle of
top hook to saddle of load hook, measured when
load hook is at upper travel limit. Smaller
headroom allows a hoist to fit in tighter work
spaces.
Hook saddle: The inside arc of the hook which
contacts the beam (top hook) or where the load
sling is seated (load hook).
Toggle or “bump fire”: Rapid press and release
of a control button to raise or lower load in
intermittent steps. (A variable frequency drive in
lowest speed range often eliminates the need for
toggling.)
Overtravel limit device: A device for limiting
upward or downward travel of the load hook at the
extremities of its lift. (If activation of the device
alters the electrical circuit within the machine, it is
often called a “limit switch.”)
Load block: The assembly of hook or shackle,
swivel, bearing, pins, sheaves and frame
suspended by the chain.
Overload limit device: A mechanical or electrical
device that prevents the hoist from lifting when
excessive load is applied.
Rated Load, or Capacity: The maximum load
weight, usually labeled as tonnage, which the hoist
is designed to handle as designated by the
manufacturer.
Reeving: The system in which a chain or rope
travels around a running sheave.
Running Sheave: A sheave which engages the
chain/rope and rotates as the load block is raised
or lowered. Also called “load sheave” or “load
sprocket.”
Variable frequency drive (“inverter”): A control
system that converts fixed line voltage and
frequency into a three-phase system with infinitely
variable voltage and frequency, in order to regulate
motor speed.

9.2 Lubrication
9.2.1 Gear oil
Your hoist has been shipped with oil included in
the gearbox. Before operating, verify the oil level
by removing the fill plug on top of the hoist, shown
in Figure 9-1. The oil level should be just below the
edge of the hole.
Check the level again after the first 100 hours of
operation, then check every 3 months. See sect.
16.1 for oil specifications.
IMPORTANT: Before operating hoist, pull out the
rubber breather plug from the top fill plug (Figure 9-
1). Reinsert this plug if hoist is to be transported or
placed in storage.
9.0 Installation
Hoist must remain disconnected from electrical supply during assembly
and installation unless instructed otherwise.
Support for the hoist may be hook, clevis pin,
trolley, or beam clamp. Whatever method of
suspension is chosen, the support components
must be rated equal to, or greater than the
capacity of the chain hoist. Supporting structures
(such as I-Beams) should be installed by properly
licensed professional installers.
If you are using the hoist with a trolley, refer to the
trolley manual for instructions on securing the
control cord and maintaining proper slack in the
cord during operation. Optional pendant cords for
use with a trolley system are shown in section
20.0.
TIP: If suspending from a trolley, do not mount the
top hook but install the hoist directly to the trolley if
possible.
Make sure the suspension system used is properly
grounded, in addition to the grounding of the hoist.
9.1 Mounting top hook
Attach the top hook with the provided lock bolt, hex
nut and cotter pin (Figure 9-1).
Figure 9-1 (BLVS050 shown)
9.2.2 Chain lubrication
Periodically apply a light coat of 30W oil to the
chain. This will create easier operation and prolong
the chain’s life. For optimum results, clean chain
with an acid-free solution before oiling.
9.3 Power cable
All electrical connections
must be made by qualified personnel. Read
sect. 10.0 before connecting this unit to power.
Connect the power cable leads to an extension
and run the line to the electrical panel, or install a
UL/CSA approved plug to draw from a receptacle.
IMPORTANT: The power cable should be directed
so that it is safely out of the way of loads. If a
trolley is used, power cable must not interfere with,
or be pinched by, trolley travel. See Figure 9-2 for
a recommended solution.
8
Figure 9-2
9.4 Controller setup
Screw the receiving antenna onto the bottom of the
hoist. See Figure 9-3. The wrist strap can be
placed on the wireless controller.
The wireless controller (transmitter) has been
synchronized to your specific hoist by the
manufacturer. If replacing a transmitter, see sect.
14.0 for instructions.
If using a wired pendant controller (optional
accessory), the antenna is not needed. Connect
the 12-pin male plug on the controller cable to the
receptacle beneath the hoist, and clip the carabiner
to the eye bolt to relieve stress on the plug
connection.
See sect. 12.1 for controller operation.
resulting in serious personal injury or property
damage.
To assemble chain container to hoist:
1. Hang hoist in position on the I-Beam or trolley.
Do not install chain container yet. Allow slack
side and load side of chain to hang freely from
hoist.
2. Apply power to hoist and press DOWN button
until limit switch is tripped.
3. Mount chain container to bracket on side of
hoist (Figures 9-1 and 9-4), using the two
socket head bolts and lock washers.
4. Place chain stop into container, and operate
hoist to bring load hook up until upper limit
switch is tripped.
5. Inspect chain to ensure that all non-loaded
chain is completely in container.

Do not dump chain by hand
into the chain container. By not following the
above steps, the chain can become twisted or
kinked and can damage the hoist.
Figure 9-3: remote controller setup
9.5 Chain container
Your hoist is supplied with a chain container
designed to fit the particular length of chain. If a
different length chain is ever installed on this hoist,
the chain container must be replaced by one of
proper size. See chart in sect. 19.0.
The chain container should be installed after the
power supply is connected to hoist.
Do not overfill chain container.
If chain should overfill and begin to fall, entire
chain container may empty without warning,
10.0 Electrical connections
Electrical connections must
be made by a qualified electrician in
compliance with all relevant codes. This
machine must be properly grounded to help
prevent electrical shock and possible fatal
injury.
The BLVS series hoist is pre-wired for 120V,
single-phase power only.
The hoist should be connected to a circuit with
current overload protection, rated at minimum
120% of the full load amperage listed on the hoist’s
nameplate. If fuses are used, they must be timedelay fuses rated “D”. Local codes take
precedence over recommendations.
10.1 GROUNDING INSTRUCTIONS
In the event of a malfunction or breakdown,
grounding provides a path of least resistance for
electric current to reduce the risk of electric shock.
This hoist is not supplied with a power plug. Power
supply cables may either be fitted with a UL/CSA-
9
listed plug rated for the appropriate phase and
voltage, or “hard-wired” directly to a control panel.
If hard-wired, make sure a disconnect is available
for the operator.
If a plug is installed, it must have an equipmentgrounding conductor and a grounding prong. The
plug must be plugged into a matching outlet that is
properly installed and grounded in accordance with
all local codes and ordinances. Do not modify the
plug – if it will not fit the outlet, have the proper
outlet installed by a qualified electrician.
Improper connection of the equipment-grounding
conductor can result in a risk of electric shock. The
conductor with insulation having an outer surface
that is green with or without yellow stripes is the
equipment-grounding connector.
If repair or replacement of the electric cord or plug
is necessary, do not connect the equipmentgrounding conductor to a live terminal.
Check with a qualified electrician or service
personnel if the grounding instructions are not
completely understood, or if in doubt as to whether
the tool is properly grounded.
Repair or replace damaged or worn cord
immediately.
10.2 Inspecting hoist motion
1. Allow 15 seconds for start-up after connecting
power supply.
2. Before closing circuit breaker and testing hoist,
check that wiring has been complete. If hoist
cannot be observed when circuit breaker is
closed, station an observer within sight of hoist
to report any movement when power is
applied. Be prepared to disconnect power if
hoist motor starts when power is applied – the
hoist must remain motionless when power is
applied. Find and correct any problems before
continuing.
3. With no load on load hook, press UP button
very briefly and observe hoist action. The hook
should move upward.
4. Run hoist to maximum lifting height, then to
maximum lowering point to ensure that limiter
devices are operating properly.
11.0 Pre-operation inspection
2. Marks on the chain surface are deeper than
5% of the link’s diameter.
3. Links are twisted or deformed.
4. Links are stretched too long or considerably
worn on the surface, especially at points where
links contact each other.
Never extend load chain by welding a second
piece to the original.
Do not operate hoist with
twisted, kinked or damaged load chain. Do not
splice load chain.
Check that chain does not twist along its length
from hoist to hook (Figure 11-1). If twist is present
on units with multiple falls, the hook has been
capsized; it must be passed back through the chain
loop to remove all twist in the chain. See Figure 11-
2.
Figure 11-1
Figure 11-2
The load chain supplied with
your JET chain hoist is designed,
manufactured, and tested for proper fit and
durability. Over a period of time, the chain may
need to be replaced. For your own safety, use
factory replacement chain only. Use of other
than factory replacement chain may cause
serious injury and/or damage to hoist.
A light coat of 30W oil applied periodically to the
chain will create easier operation and prolong
chain life.
11.1 Inspecting load chain
Clean chain with non-acidic solution, and carefully
inspect entire load chain. Replace damaged chain
before using hoist. Use provided chain gauge and
refer to sect. 18.2. Replace worn chain.
Also replace the load chain if any of the following
are identified:
1. Seriously rusted or cracked.
11.2 Inspecting hooks
It is important to check top and bottom hooks for
proper opening and other signs of deformation or
damage. Replace a hook immediately if any of the
following problems are identified:
1. The safety latch is damaged or bent, or no
longer has sufficient spring pressure to contact
the hook tip.
10
2. The vertical angle at neck of the hook reaches
10 (see Figure 11-3).
Figure 11-3
3. Chemical corrosion or cracks on the hook.
4. Excessive wear on the inside surface.
5. The throat opening has enlarged. (See sect.
18.1 for maximum allowable limits for the
throat opening.)
NOTE: Excessive hook throat opening or twist
indicates abuse or overloading of the hoist. If such
deformation is discovered, inspect hoist, chain and
all supporting members very carefully for additional
indications of excessive hoist loading.
Press and hold a button firmly; avoid excessive
inching. Allow at least one second before switching
between UP and DOWN buttons; hoist will not
move if the transition is too quick.
The UP and DOWN buttons are two-step. Press
lightly for slower speed, press fully for faster speed.
Press the red emergency stop button (“E-stop”) to
shut off power; the button remains locked and
prevents any movement of the hoist. To restart,
rotate stop button clockwise until it disengages.
Do not attempt repair of a
hook by heat treating, bending or attaching
anything by welding. Such procedures will
weaken and may cause failure of the hook.
12.0 Operation
Read all safety instructions in sect. 1.0 before
operating this hoist.
12.1 Controls
Refer to Figure 12-1.
Allow hoist to come to a full
stop before changing direction. Rapidly
reversing or catching a falling load can
overload the hoist system and cause failure in
hoist and/or chain, resulting in injury or
property damage.
The wireless controller is provided with the hoist.
An optional wired pendant controller is available.
See sect. 20.0.
Press START on wireless controller. To lift a load,
press and hold the UP button. To lower, press and
hold the DOWN button. Adjust speed using the
dial.
Pressing START button during operation will sound
the horn.
Figure 12-1
The wireless controller has a “zero-G” sensor: If
the unit is dropped, thrown, or receives a sudden
impact, commands will be disabled, to prevent
accidental hoist movement.
The wireless controller is powered by (2) AA
batteries, which may require occasional
replacement.
12.2 General procedure
If hoist is connected to a manual trolley, move hoist
by pushing on the suspended load. Move an
unloaded hoist by pulling on the empty hook. Do
NOT move hoist by pulling on control cord.
Always keep hoist clean, and store in a clean, dry
location.
Avoid lifting one load with two hoists. If this is
unavoidable, apply equal weight to both hoists and
use hoists with proper lift capacity. Capacity of
each hoist must be equal to the total load to be
lifted.
11
Follow this general procedure for hoisting loads:
1. Secure upper hook to the supporting structure.
2. Place load sling or chain in center of bottom
hook, making sure the safety latch is secure.
Never load the hook in front of the safety
latch. See Figure 12-2.
Figure 12-2
3. Press UP button (slow speed) and remove all
slack in load chain. Increase tension in load
chain until hoist is about to raise the load.
4. Check again that load is properly slung, is
directly under hoist, and will not suddenly
swing or twist.
5. Raise load an inch or two above ground and
stop. Observe load for a few moments, looking
for signs that load or hoist system is unstable,
or other indications of a problem.
6. Check that chain is not twisted at bottom hook.
All welds should face same direction (see
Figure 11-1). For hoists with two or more falls
of chain, make sure bottom hook is not
capsized. This may cause the chain to twist.
7. Raise load to traveling height. Raise only to
height necessary to safely clear all obstacles.
8. Lower load at destination. If both UP and
DOWN commands must be used during
lowering, pause for a moment between each
reversal of load direction.
9. Slowly allow weight to shift from hoist to
ground or new support. Do not approach load
until all tension is out of chain and load is
stable.
10. Press red stop button to lock out hoist
movement until load has been unhooked.
11. Always leave bottom hook and pendant
controls in a vertical, static position, never in a
position that can produce swing or slip.

13.1 Replacing load chain
Over time, the load chain will wear or elongate.
This can cause damage to hoist, breakage, or nonengagement of the load sheave. The following
procedures describe replacing the load chain for
single and multiple fall hoists. These procedures
must be performed by qualified persons only.
It is recommended that after installing new chain,
the first few lifts be limited to no more than 25-50%
of rated load capacity. Thoroughly inspect new
chain for twist before placing hoist into routine
service.
IMPORTANT: Due to the internal space of hoist,
additional length must be added to the nominal
chain length, as shown in Table 2. For example,
model BLVS018 with 10 ft. lift requires 10.66 ft. of
chain.
Model Additional length of chain
BLVS018 0.66 ft.
BLVS025 0.66 ft.
BLVS050 1.32 ft.
BLVS100 1.65 ft.
BLVS200 3.3 ft.
Table 3
13.1.1 Cutting chain
Use eye/face protection when
cutting chain.
Use a bolt cutter with special cutter jaws for cutting
hardened chain. Cut only one side of the link at a
time. When making the second cut, place a mat
over the chain to catch the flying chain section.
(Note that the following Figures may or may not
show your particular hoist model, but the procedure
is identical.)
13.1.2 Single fall chain hoist
1. Locate the flexible chain puller that was
provided with your hoist.
2. Lower the load hook until only 1 to 2 feet of
slack chain remains in the chain container.
3. Remove chain container.
4. On the slack side of the chain, remove the
chain stop, spring, and plates (Figure 13-1).
Keep these handy for later re-installing.
12.3 Load brake function
The mechanical load brake holds a full capacity
load independent of the motor brake, and prevents
load from accelerating during lowering process.
12
Figure 13-1
5. Keep tension on chain and press DOWN on
controller until slack end of old chain comes
free of the hoist.
6. Insert chain puller through hoist as shown in
Figure 13-2.
7. Connect hook of chain puller to the link on new
chain (Figure 13-3), and pull chain through
until it engages the sprocket. Do not let the
chain twist or bind as it is being pulled
through the hoist.
10. Install chain container, making sure to install
the self-locking nut on the screw. Do not fill
chain container by hand.
11. Remove load hook from old chain and install
on new chain end.
12. Test limit switches by raising and lowering
hook. Inspect chain for any signs of twist or
binding, and correct before continuing.
13. Lubricate new chain with light coat of oil.
13.1.3 Vertical and horizontal links
Vertical and horizontal are determined by the
relationship to the load chain sheave. Vertical links
will be guided by the center slit in the sheave.
Horizontal links will engage the oval pockets on the
sheave. See Figure 13-4.
Figure 13-2
Figure 13-3
8. Keep tension on the end of the new chain and
press the DOWN button on the controller, until
chain clears the hoist. Stop hoist when 1 to 2
feet of new chain remains on the slack side.
9. Install the chain stop, spring and plates (Figure
13-1) on the slack end of the chain.
Figure 13-4
13.1.4 Double fall chain hoists
The link on the load side end
must be a vertical link. If it is a horizontal link,
the chain will have a twist in it.
1. Locate the flexible chain puller that was
provided with your hoist.
2. Lower the load hook until only 1 to 2 feet of
slack chain remains in the chain container.
3. Remove chain container.
4. On the slack end of the chain, remove the
chain stop, spring, and plates (Figure 13-1).
Keep these handy for later re-installing.
5. Keep tension on chain and press DOWN on

The link on the load side
end must be a vertical link, as shown in
Figure 13-3. If it is a horizontal link, the
chain will have a twist in it.
8. Press DOWN on controller while pulling chain
through until it completely engages the
sprocket and emerges from other side. Do not
let the chain twist or bind as it is being pulled
through the hoist.
9. Keep tension on the end of the new chain and
press DOWN on the controller, until 1 to 2 feet
of new chain remains on the slack side.
10. Install the chain stop, spring, and plates
(Figure 13-1) on the slack end of the chain.
11. Install chain container, making sure to install
the self-locking nut on the screw. Do not fill
chain container by hand.
12. Press UP button to further lower some of the
slack end of chain into container, while
keeping light tension on the load end of chain.
13. Attach the load hook using the chain puller, as
shown in Figure 13-5.

16.0 Inspection and maintenance
All repairs and adjustments are to be performed by qualified persons using
procedures that are approved for the hoist system being serviced. All safety-related deficiencies
discovered in the inspection are to be corrected before hoist is placed back into service. Check for
internal damage whenever external damage has occurred.
Appropriate LOCK OUT/TAG OUT procedures must be followed when performing maintenance.
Read and follow all relevant ANSI Inspection and Maintenance standards, particularly ANSI/ASME B30.16
Overhead Hoists (Underhung). Know the meaning of Frequent Inspection, Periodic Inspection, Normal Service,
Heavy Service, and Severe Service. It is the customer’s responsibility to understand and follow all ANSI and
JET inspection and maintenance instructions.
The following definitions are based upon ANSI/ASME B30.16.
Normal Service: Operation with randomly distributed loads within the rated load limit or uniform loads less
than 65% of rated load for not more than 25% of the time.
Heavy Service: Operation within rated load limit, which exceeds normal service.
Severe Service: Normal or heavy service with abnormal operating conditions.
Designated Person: A person selected or assigned as being competent to perform the specific duties to
which he/she is assigned.
Qualified Person: A person who, by a recognized degree or certificate of professional standing, or who,
by extensive knowledge, training, and experience, has successfully demonstrated the ability to solve or
resolve problems relating to the subject matter and work.
16.1 Gearbox oil
The oil in the gearbox should be changed annually, or more frequently under severe service, as follows.

17.0 Inspection schedules
The TS series Hoist should be given an initial inspection upon installation and prior to use (see also Pre-
Operation Inspection in this manual). Following that, it must be inspected by a designated person at the time
interval noted below. Dated inspection and repair reports must be maintained. Copies of all reports must be
available to service personnel.
Visual inspections are divided into two general classifications based upon frequency, then further categorized
by type of service, as shown below.
More detailed information may be found in ANSI/ASME B30.16 standards publication.
FREQUENT Inspection Schedule
Service Interval:
Normal Service: Monthly
Heavy Service: Weekly
Severe Service: Daily
1. Check oil level in gearbox.
2. Check braking system for slippage.
3. Check that pushbutton controls and
emergency stop operate properly.
4. Check that limit switches function properly.
Without load, operate UP button control while
observing limit spring. If limit spring becomes
compressed and motor does not stop, STOP
operation immediately. Limit switch is not
operating properly. Repeat test with DOWN
button control.
5. Check top hook and load hook for deformation,
chemical damage, and cracks.
6. Check hook latch operation.
7. Check that load chain is clean and lightly
lubricated, free of excessive wear or
deformation at the contact points between
links and link and hook (see section 17.0 in
this manual). This hoist uses special alloy
hoisting chain and does not interchange with
any other manufacturer. All replacement chain
must be purchased from your JET distributor
or from JET directly by calling 800-274-6848.
8. Check that the chain passes smoothly through
all sprockets while under load.
9. Check entire hoist system for signs of damage
and loss of integrity. Listen for any abnormal
sounds.
PERIODIC Inspection Schedule
Service Interval:
Normal Service: Yearly
Heavy Service: Semi-Annually
Severe Service: Quarterly
1. Perform all of the Frequent Inspection items.
2. Drain and refill gearbox. (See section 10.2.1
for details and capacities.)
3. Check entire unit for loose screws, bolts, nuts,
rivets and pins.
4. Check for evidence of excessive wear,
corrosion, cracks, or distortion in the following
parts: hook parts, chain attachments,
suspension bolts and shafts, housings, gears,
bearings, pins, rollers, and locking and
clamping devices.
5. Check for evidence of damage to hook parts
including hook retaining nuts and collars and
pins, and hook holding frame and parts used
to secure the frame.
6. Check for evidence of damage or excessive
wear of load gear, sheave and sprocket wheel.
If the pockets are too deep, the chain may jam
with corresponding failure of engagement
between chain and sprocket or sheave.
7. Check for evidence of excessive load brake
wear. Inspect clearance between brake
components, and adjust if needed.
8. Check for evidence of pitting or other
deterioration of visible controller contacts.
9. Check for evidence of deterioration of
supporting structures and trolleys.
10. Check for visible deformation of limit switch
coil springs.
11. Check that all warning labels are present and
legible.
