Prior to installing unit, carefully inspect it for possible shipping damage.
• Owners and users are advised to examine specific, local or other
regulations, including American National Standards Institute and/or
OSHA Regulations which may apply to a particular type of use of this
product before installing or putting the unit into use.
• Before installing, read "SAFETY INFORMATION".
Ensure unit is properly installed. A little extra time and effort in doing so
can contribute a lot toward preventing accidents, injuries and will help
achieve the best service possible.
• Lubrication of the EZ-Torque Tube is not recommended.
Adjustments
Prior to operating the EZ-Torque Tube, but after installation, ensure the
following adjustments, as they apply to your assembly and optional
components, are made:
1.
If necessary, adjust air regulator as described in this section. Refer to
"Regulator Installation" and "Operational Adjustments".
2.
If an air cylinder is used, ensure air cylinder is correctly installed,
fasteners are tightened and any adjustments are complete in
accordance with manufacturer's instructions.
3.
If a spring balancer is used, ensure spring balancer is correctly
installed, tested and performing in accordance with manufacturer's
instructions.
Regulator Installation
Refer to Dwgs. MHP1703 on page 3 and MHP1675 on page 64.
The regulator is connected with a connector fitting (36), elbow (37) and a
check valve (26). Connector fitting (36) should be threaded into rod end
port on air cylinder. Check valve (26) will be threaded into elbow (37),
which is threaded into the regulator input.
• Arrow on the check valve (26) must be pointing towards cylinder. If
check valve is installed backwards, cylinder will not function.

Operational Adjustments
To establish a "zero gravity" condition for the operator to manipulate the
tool, complete the following adjustment procedures:
• Prior to performing operational adjustments, or servicing, ensure
air supply is off and unit is not under load.
1.
Turn adjustment knob (21) counterclockwise until unit stops.
2.
Attach tool to unit. This will require tool be installed in tool holder.
Connect coiled air tube.
3.
Turn on air supply.
4.
Turn adjustment knob clockwise until tool begins to move.
Regulator is properly set when equal effort is required to raise and
lower the tool.
5.
Tighten locknut on regulator stem to lock adjustment in position.
An air supply system is required for EZ-Torque Tubes equipped with an
air cylinder and/or air operated tool.
Supply air must be clean and free from water, water vapor and oil. 6.9 bar/
690 kPa (100 psig) at the unit is required to provide rated capacity. Do not
exceed 6.9 bar/690 kPa (100 psig).
• Do not use an air line lubricator of any kind. Oil may damage
internal components.
Check tool manufacturer's specifications for correct air supply
requirements.
Air Lines
The inside diameter of the air supply lines should not be smaller than 10
mm (3/8 inch) based on a maximum of 30 metres (100 feet) between the
air supply and the unit. Contact the factory for recommended air line sizes
for distances greater than 30 metres (100 feet). Before making final
connections, all air supply lines should be purged. Supply lines should be
as short and straight as installation conditions will permit. Long
transmission lines and excessive use of fittings, elbows, tees, globe valves,
etc. cause a reduction in pressure due to restrictions and surface friction in
the lines. If quick-disconnect fittings are used at the inlet of the unit, they
must have at least a 10 mm (3/8 inch) air passage. Use of smaller fittings
may affect performance.
