TOOL MAINTENANCE

The most common reason for poor tool performance and incorrectly formed straps joints is
improper tool maintenance. The easiest way to determine if a tool is performing correctly is by
inspecting the strap joint. Having a tool maintenance program is a simple task which consists of
three parts. First, a quick daily inspection of the tool for any worn or broken parts. Secondly,
keep each tool on a schedule of service intervals for cleaning and lubrication. Third, when
problems do occur, use the troubleshooting guide to properly determine and fix problems before
they lead to more serious tool conditions. Each of these three tasks have been outlined for this
particular tool, read and understand all information for improving the life and performance of the
tool.

TOOL INSPECTION

Visually inspect the exterior of the tool on a daily basis. Decreased tool life can be prevented by
early detection of broken parts. Replace all broken parts with new parts. Review the Parts
Removal, Replacement & Adjustments portion of this manual for information and details.

SERVICE INTERVALS

This tool, like most Signode tools, can be used with various sizes of strap which cause different
rates of component wear. Also, wear is affected by the environment and tension that the tool
applies. In the worst case, heavy gauge wide strapping. All critical moving components of the
tool should be inspected at particular intervals, some more often than others. Broken parts can
decrease sealing effort, leading to additional component wear and produce lower joint strength.

Inspect the components of the sealing mechanism when:

A. Joint does not appear as shown in this manual or visually it is detected that the joint is

not all formed or formed improperly.

B. Sealing effort requires higher air pressure or tool is difficult to remove from strap.
C. When scheduled.

 If there is any question that joint formation is not as shown or is

suspect, it is important that you contact your tool representative immediately.  

The feed wheel and wear plug are also subject to wear and chipping. A daily cleaning of these
parts by brushing off debris will be important to maintaining long life. The first indication of wear
will be strap slippage during tensioning. The operator of the tool should be instructed on how to
determine when the strap slips during tensioning. Sometimes the teeth need to be cleaned with a
wire brush, but if slipping is allowed to continue, the parts will need to be replaced. Using the
tool in a dirty environment will increase feedwheel wear.

NOTE: On some Signode tools the feedwheel can be cleaned by holding the tool open in the
strap loading position while the tool runs without strap and using a wire brush to clean the
feedwheel as it rotates.  

Inspect the components of the tensioner mechanism when:

A. Strap slips when being tensioned.  
B. Evidence of feedwheel milling on the strap face.
C. When scheduled.

TOOL LUBRICATION

Signode tools use a variety of greases and oils, all of which can be ordered through Signode.
When ordering indicate tool model, part number and name.
