Your product PROFI 2 TI is designed for lifting and
lowering loads in the range of the rated load ca-
pacity with a vertically arranged chain.
Your product is also suitable for pulling loads hori-
zontally.
In combination with a trolley, your hoist is also suit-
able for overhead horizontal movement of loads.
Under certain conditions, however, lifting person-
nel suspension means is allowed in cases of ex-
ception. However, it is prohibited to transport peo-
ple.
Please observe the following national legal provi-
sions. Any other or exceeding use is considered
improper. J.D. Neuhaus GmbH & Co. KG assumes
no liability for damage resulting from this improper
use. The risk is borne solely by the user.
Proper use also includes the observance of the
operating instructions and compliance with the
inspection and maintenance conditions.
3.2. Improper use
Among others, the following are considered im-
proper uses
•Changing load capacities with the load posi-
tion: Your product is not equipped with a load
capacity display, which is why it may only be
used in such cases where the load capacity
does not change with the load position
•Exceeding the load capacity
•Breaking free or towing loads
•Load the hook at the tip
•Catching falling loads
•Transporting people (→section 3.1, page 11).
•Jog controls
•For ongoing motion, switch in the opposite
direction

Doc.-No.: VA058498-50-OM-EN-1021-62-2 Page 11 of 62

PRODUCT INFORMATION
Definition of oblique pulling (→Figure 1)
Figure 1: Oblique pulling
Oblique pulling is the deviation from the vertical
position of the load chain and the chain hoist in
the straight course of the force line between the
point of application of force of the load on the load
hook and the suspension on the carrying structure
(α6= 0◦).
Using special safety precautions that are ap-
propriate for the respective situation, your prod-
uct PROFI 2 TI can be used for diagonal pull. In
the process, a chain box may not be used, as
the chain could fall out here or become knotted.
Please contact us if necessary.
For other foreseeable misuses:
→Rules for safe operation, page 35
Your product PROFI 2 TI may not be used in the
following areas:
•critical areas in nuclear plants
•over acid baths or systems with aggressive
substances
•in areas where there are organic acids
•in areas outside of the permissible ambient

in the event of light alloy metal or other impact
sensitive dusts. The permissible ambient tempera-
ture range is from -20◦C (-4◦F) to +40◦C (+104◦F).
For more information about explosion protection
→Section 3.10, Page 21
3.5.4. Vane motor
The vane motor (→Figure 4) consists of a cylin-
der liner (1) with two lateral bearing washers and
an inner rotor (2).
The rotor is mounted eccentrically in the cylinder
liner and is provided with slots (3) for holding the
slats (4).
The slots can move freely and are on the inner
wall (5) of the cylinder liner. Two slots form a
chamber (6).
The incoming compressed air creates a greater
force at the leading larger slot surface (4.1) than at
the following smaller slot surface (4.2). The rotor’s
torque results from the difference in force.
The compressed air can again escape when pass-
ing through the outlet opening (7) Lubricant cham-
bers (8) are arranged between the vane slots of
the rotor. They ensure a continuous motor lubrica-
tion (not applicable for mini).
The arrows in the illustration indicate the direction
of rotation of the rotor and the corresponding path
of the compressed air.

motor
Page 14 of 62 Doc.-No.: VA058498-50-OM-EN-1021-62-2

PRODUCT INFORMATION
3.5.5. Motor lubrication
The JDN high performance grease contained in
the motor allows for operation with oil-free com-
pressed air.
It works over an operating time of about 250 hours
and should, however, be replaced as required, but
after five years at the latest.
3.5.6. Control
The lifting and lowering motion is controlled di-
rectly from the rope control (→Figure 5) One-
handed sensitive operation is possible. The di-
rection of movement is indicated by arrows.
ILifting: Carefully pull on the rope with the
green handle cone. The load will be lifted
slowly.
IPull on the rope harder to increase the lifting
speed.
IEase up on the rope slightly to reduce the lift-
ing speed.
ILowering: Carefully pull on the rope with the
yellow handle cone. The load will be lowered
slowly.
IPull on the end of the rope harder to increase
the lowering speed.
IEase up on the rope slightly to reduce the
lowering speed.
Figure 5: Control
The control system is suitable for use in explosive
areas.
All control switches automatically return to the
neutral position when released. All movements are
stopped instantaneously and the load is securely
held in its current position.
3.5.7. EMERGENCY STOP device
The lifting and lowering motion is controlled di-
rectly from the rope control.
The control devices of the rope control and the
energy-switching part of the control valve on the
motor (reversing valve) are positively linked with
each other. This connection is designed so that
the control valve can be reset to a stable neutral
position in cases of emergency. This means that
no other EMERGENCY STOP device is neces-
sary.

PRODUCT INFORMATION
3.5.8. Lifting limiter
WARNING
Danger from chain fracture
If the buffers are damaged, unacceptably high
loads may act on the chain when starting the
lifting limiter. The chain may break.
IDo not use product
IHave product repaired (replace buffer)
NOTICE
The lifting limiter may only be started in cases of
emergency. The operator must monitor the load
hook movement and stop the lifting movement in
due time. Striking the buffer against the housing
is to be avoided. This may result in damage to the
buffers.
Your product is equipped with a limiter that limits
the lifting movement (→Figure 6).
In order to achieve a limitation of the lifting move-
ment, a buffer (1) is mounted to the bottom block /
load sleeve. If the buffer is moderately deformed
in the boundary layer, the overload protection
switches the motor off.
Figure 6: Lifting limiter
3.5.9. Lowering limiter
WARNING
Danger from chain fracture
If the buffer is damaged, unacceptably high loads
may act on the chain when starting the lowering
limiter. The chain may break.
IDo not use product
IHave product repaired (replace buffer)
NOTICE
The lowering limiter may only be started in cases
of emergency. The operator must monitor the load
hook movement and stop the lowering movement
in due time. Striking the buffer against the housing
is to be avoided. This may result in damage to the
buffers.
Your product is equipped with a limiter that limits
the lowering movement (→Figure 7).
In order to achieve this, a buffer (1) is mounted to
the empty end of the part of the chain. The motor
is not switched off.
Figure 7: Lowering limiter
Page 16 of 62 Doc.-No.: VA058498-50-OM-EN-1021-62-2

PRODUCT INFORMATION
3.5.10. Load hook
NOTICE
Load hooks may not be loaded at the top. They
may not be directed or annealed. This may result
in damage to the load hook.
If the load hook is bent, your productPROFI 2 TI
must be inspected.
The permissible temperature range is -40◦C (-
40◦F) to +150◦C (302◦F).
3.5.11. Chain
WARNING
Danger from chain fracture
The fatigue strength of chains is significantly im-
paired by extreme corrosion (pitting corrosion). In
addition, rusty chains result in heavy wear. There
is a danger of breakage!
IDo not use rusty chains
WARNING
Danger from chain fracture
Hydrogen-induced embrittlement with subsequent
stress corrosion from highly corrosive media (e.g.
sea water) may appear on high-strength alloys
(e.g. on the chain). There is a danger of break-
age!
So-called recombination toxins promote this
process. Hydrogen sulphides, cyanide, arsenic
compounds and thiocyanates are known for this.
IProtect the chain against strong corrosion
NOTICE
JDN chains are matched in close tolerances to
the sprocket. In order to ensure an optimum func-
tion of the chain and in order to prevent dangers,
only genuine JDN chains may be installed.
Your product PROFI 2 TI has 2 falls and the chain
size 7 x 21.
Your product was shipped without a chain. Assem-
bly chains are inserted for the installation of the
chain.
Doc.-No.: VA058498-50-OM-EN-1021-62-2 Page 17 of 62

PRODUCT INFORMATION
3.5.12. Dead end chain mount
WARNING
Danger from falling chain
It is important to ensure that the idle chain (un-
loaded chain end) accumulating on or sagging
from the sprocket does not cause any hazard,
such as from catching, impacting or falling.
There may be hazards from the chain falling if the
idle chain is first deposited on a load with a large
surface when lifting and then slides off and drops.
IEnsure that the chain does not get caught, hit
anything or fall down.
The last link of the dead end chain mount (un-
loaded chain end) is attached to the empty strand
anchorage (→Figure 8 (1)). This serves the pur-
pose that the empty chain strand does not dangle
so long and thus cannot lead to the hazardous sit-
uations listed above.
Figure 8: Dead end chain mount
3.6. Emissions
3.6.1. Noise emissions
When lifting the nominal load, the sound pressure
level is 76 dB(A). When lowering the nominal load,
the sound pressure level is 78 dB(A).
The decrease of the sound pressure level in the
hall is about 3 dB(A) per distance doubling.
3.6.2. Oil emissions
When operating with oil lubrication of the motor,
small amounts of lubricating oil are discharged into
the environment with the exhaust air.
3.7. Conditions of use
Your product PROFI 2 TI is very sturdy and re-
quires very little maintenance. It is suitable for ap-
plications in explosive areas as well as in areas
with increased concentrations of soot, dust, hu-
midity and ambient temperatures from to , if it is
not heated up further due to external influences.
The thermal resistance of the chain and hook is
150◦C (302◦F).
For stationary use outdoors, you must protect your
product against the effects of weather and shorten
the maintenance intervals.
Stopping and securing against the wind is required
upon reaching a critical wind surge pressure. The
critical wind surge pressure depends, among other
things, on the mass and shape of the load to be
lifted.

PRODUCT INFORMATION
3.8. Power requirement
3.8.1. Connections
The connection for the compressed air supply has
the size G 1/2.
Please use the corresponding hose lines for the
selected pressure.
3.8.2. Pressure
WARNING
Danger of explosion
Operating at higher system pressures may result
in hazards due to overload.
When operating at lower system pressures, the
brake can grind and is therefore subject to very
high wear. Inadmissibly high heating may result.
The load capacity of the device is reduced. The
response of the control system decreases notice-
ably.
IComply with the specified pressure.
Your product PROFI 2 TI must be operated with a
nominal pressure of 6bar (85psi) (see specification
on the nameplate).
Air pressure conditions during operation (→
Figure 9)
The system pressure existing in the line must cor-
respond to the nominal pressure. Higher pres-
sures must be reduced.
After switching on, the adjoining nominal pressure
p1 reduces to the actual pressure p2. The extent
of the actual pressure p2 at which the product is
operated is dependent on
•the weight of the load (2) and the
•direction of movement of the load (3) .
When lifting the nominal load (load capacity) at the
specified lifting speed, the actual pressure p2 may
at a maximum be 10% below the specified nomi-

3.8.4. Quality of the compressed air
NOTICE
There is a danger of icing in the motor if there is
moist air and ambient temperatures at or below
0◦C (32◦F)!
You can avoid icing by:
IConnecting an air dehydrator upstream
IWhen using a service unit with an oiler, de-
pending on the moisture content of the com-
pressed air, add an anti-icing agent to the lubri-
cating oil or use an air lubricator (type no. 11900)
with an anti-icing addictive for the corresponding
temperatures.
Your product PROFI 2 TI must be operated with a
sufficiently clean and dry working air. The working
air must meet the following quality requirements:
•Particle size less than 40µm (1,57mils)
•Particle density smaller than 10 mg
m3(entspricht
Class 7 nach ISO 8573-1 : 2001)
To provide a sufficient compressed air quality, we
recommend operation with a filter regulator.
The pressure condensation point must be at least
10K below the lowest expected ambient tempera-
ture.
Do not operate your product with other gases!
3.9. Operating materials
CAUTION
Danger of skin irritation
Oils and greases may cause skin irritation.
IWear protective gloves
NOTICE
Do not mix synthetic oils or greases with mineral
oils or greases, as the properties may deterio-
rate. Also never mix different types of lubricating
grease within the synthetic or mineral lubricant
groups. When operating with oilers, synthetic
lubricants may never be used. Alcohols are not
permitted as de-icing agents.
The following operating materials and lubricants
are intended for normal environmental influences.
In the event of environmental influences that pro-
mote wear, please contact J.D. Neuhaus to obtain
appropriate information.
