mist.
The specification is valid up to a height of 800 m
above sea level.
Transport and storage
Store pump in a dry area. Prevent condensation
caused by vapour.
Lift and transport only by using the ring screws.
Installation
It is recommended to install the pumps with easy
access for maintenance.
Clearance between compressors and adjacent
walls should be no less than 10 cm of free space
in order to ensure sufficient air flow for cooling.
Contact TAWI prior to installation
under noise insulation canopies.
Ambient temperatures must not exceed 45°C.
Connection and installation
Ensure correct dimensions (see Table) and clean
pipelines (no weld spatter, chips or similar contamination).
With pipelines exceeding 5 m in length we
recommend the installation of non-return valves.
Keep connections free from oil, grease, water
and other contaminants.
Remove end caps at DA and SA. Do not connect
to pipeline yet.
Motor connection
Connect the pump to the electricity supply
observing all applicable safety regulations. Comply
with EN 60204 T1.
Connect motor based on connecting diagram (in
terminal box) or ready-made plugs. This work
should be carried out by an experienced electrician
only. Check for connecting voltage and frequency.
Install motor circuit-breaker and set to nominal
motor current. (For data see motor rating plate).
Avoid switching of more than 10 times per hour.

more information.
Maintenance
Maintain pump regularly to achieve the best operating
results. Maintenance intervals will depend
on the pump´s use and ambient conditions.
Before commencing maintenance, remove mains
plug from socket to avoid unintentional restarting.
The filter cartridges are inserted behind the
enclosure cover GD. Clean depending on dust
accumulation. Blow out filter from inside to outside.
Replace blocked, oily or greasy cartridges.
The built-in filter is designed for clean environments.
Additional filters are available and recommended for
operation in dusty environments.
Blow out dirt in cooling air channels KK by compressed
air.
The vanes are subject to wear due to abrasion
from the walls of the enclosure.
Check vane width every 3000 operating hours or
annually (for minimum widths see Table). Remove
housing cover GD and side cover SD for this.
On replacement blow out enclosure by dry compressed
air.
The roller bearings are prelubricated for life and
will thus not require maintenance. Replace by original
roller bearings only.

What is a VacuCobra?
VacuCobra is a lifting device that uses vacuum from
a vacuum pump to hold and move a load thus
creating a smooth, safe and efficient operation.
Maximum lifting height for VacuCobra is 1,8 metres
and maximum load capacity 30 kg.
VacuCobra consists of 2 main parts:
Lift unit:
- Swivel with suspension point
- Lift tube
- Suction head
- Suction foot
Motor unit:
- Vacuum pump with built-in silencer and filter unit
- Air tube
Assembly Instructions
- Connect air tube to nozzle on the top swivel.
- Suspend the lift unit onto the trolley of a jib
crane or over head crane system. The unit must
hang freely so that unnecessary wear is avoided.
The lowest point of the suction foot must not be
closer to the floor than 15 cm. If the work place
has more than one level the unit must be
adjusted to the lowest level.
- The over head crane system for the lift tube must
be designed for minimum 1,5 x lifting capacity of
the lift tube.
- Check that the crane system is level and moving
freely. When not in operation the lift unit must
not drift or move.
- Mount the vacuum pump unit in a suitable
position and connect it to the power supply.
Check that a motor circuit-breaker is fitted and
set to the normal current shown on the motor
serial plate.
- Follow the separate instructions for the pump.
- Connect the air tube to the vacuum pump.
WARNING!
VacuEasylift must not be used by anyone who has not
received proper training. Stay clear of the area
underneath and above the load.
This unit must be operated only
by trained operators.
If incorrectly used it may cause
damage and injury to operators.
All instructions in manual must
be followed at all times.
WARNING!
Do not walk under
suspended goods.
WARNING!
Eliminate risk of
hands or feet getting
caught under
suspended load.
WARNING!
Use only the handle
to move the load.
WARNING!
Always check the
unloading area before
lowering the load.

USERS GUIDE
1. Start the motor
2. Balance the unit
The VacuCobra can be vertically balanced without
load so that it is always at a convenient and
comfortable distance from the operator. See picture
below for instructions.
Adjusting the lift unit vertically, view from below.
Turn the adjustment knob slowly for desired level of
balance.
3. Get to know the controls
The fingertip control (green arrow) is pushed toward
the operator for downwards motion.
The thumb control (red arrow) is a quick-release
function. Press away from operator to release load.
(See picture below).
Controls for downwards motion and quick-release function.

4. Adjusting the hand controls
The quick-release control can be installed on the
right- AND the lefthand side to fit both left- and right
handed operators. Moving the control is easy: pull to
free and press to install in new position. (See picture
below).
Changing position for the quick-release control.
VacuCobra is now ready to operate!
5. Grip the VacuCobra handle!
6. Lift the load
Place the VacuCobra above the load. Lower the
VacuCobra by pulling the fingertip control (silver)
towards the operator. As soon as the suction cup
reaches the surface of the load it will automatically
grip. The load can now be lifted.
Upwards motion is automatic. Use the fingertip
control (silver, for downwards motion) to decrease the
lifting speed to a desired level.
Move the load horisontally using the overhead crane
system or jib crane in which the VacuCobra is
suspended.

7. Release the load
When the load is in position above the point of
release it can be released using one of two
alternative methods:
Alternative 1. Push the quick-release control (red)
away from the operator. The suction cup will
IMMEDIATELY release the load. Make sure that no
person is occupying the area under the lift unit
when load is released!
Alternative 2. Pull the fingertip control (silver) towards the
operator for downwards motion. When the load is resting
on a surface, tilt the suction cup to allow air to pass
between the load and the suction cup. At the same time,
release the fingertip control and the lift unit will move
upwards without the load.
8. Rotate the load
The standard version VacuCobra is delivered with two
swivels. One top swivel which rotates (unlimited) the
complete lift unit in the point of suspension. And a
bottom swivel which allows individual rotation
(unlimited) of the load, a very helpful feature for high
precision handling demands.
A bottom swivel allows unlimited rotation of the load around the
lift unit axis. (Horisontal rotation).
When there is no need for high precision positioning
demands, the VacuCobra can be delivered without the
bottom swivel. A rigid grip on the load (as opposed to a
rotatable grip) makes it possible to work the unit with one
hand only.

9. Lift from the side
VacuCobra has an angle adapter which makes it just
as easy to grip the load from the side as from the top.
Place the suction cup next to the load, above the
centre. Use the fingertip control (silver) to move the
lift unit downwards while simultaneously pushing the
cup towards the load slightly. The suction cup will
automatically turn 90 degrees and grip the side of the
load. Release the control and the VacuCobra will
move upwards, allowing the load to be swung down
under the lift unit in a steady grip.

Maintenance
Check daily:
- That the lift unit achieves
maximum lifting capacity
(lifting capacity is reduced if a
vacuum leak occurs in the lift
tube or air tube.)
- That the rubber gasket on the
suction foot shows no signs of
damage or wear. A damaged
gasket must be replaced.
- That the air filter is cleaned
on a regular basis, daily,
weekly or monthly depending
on the working environment.
Instruction for this are found
in the pump section of this
manual.
- Check the overhead crane
system or jib crane in which
the lift unit is suspended on a
regular basis. Look for sign of
wear and fatigue in all parts.
See separate maintenance
instructions for these products.
The top swivel joint includes a
safety valve. The valve
automatically closes if the power
fails and the load sinks to the
floor under control. Check the
operation of the safety valve by
suspending a load and then
stopping the vacuum pump.
A controlled sinking motion is
correct – anything else: contact
your VacuCobra dealer
immediately. Check the safety
valve operation on a weekly basis.
NEVER WALK UNDER LOAD.
USE ONLY TAWI manufactured
suction feet.
