TROUBLESHOOTING

The following items are the most common types of tool malfunctions. For symptoms or remedies
not shown, contact your Signode service representative for additional information and details. The
following tool conditions are shown in this manual:

 AIR SUPPLY
 #1 - The air motor is frozen.
 #2 - A leaking or sticking air valve.
 #3 - The tool runs sluggishly.

 TENSIONING
 #4 - Feedwheel milling on strap and/or strap breaking.
 #5 - The top strap is being properly tensioned but the tool does not hold the bottom strap.
 #6 - The tool stops tensioning before maximum tension is reached (air motor continues to run).

 WELDING
 #7 - A poor weld identified by an incomplete area of weld.
 #8 - Incomplete or no weld.
 #9 - Strap is over welded.
 #10 - Motor shut-off is sluggish.
 #11 - Strap weld time is erratic.
 #12 - Weld time is too long.

 CUT-OFF ACTION
 #13 - The cut-off has become difficult.
 #14 - Weld strap is misaligned.

#1 CONDITION: The air motor is frozen.   

CAUSE

REMEDY

The motor is dry, hindering it from providing
maximum performance.

Add several drops of oil into the motor through the
air inlet.  Hook the tool up to air, depress and hold the
operating lever while gently tapping the motor with a
rubber mallet.  Repeat this procedure several times if
necessary. 

#2 CONDITION: Air valve leaking or sticking.   

CAUSE

REMEDY

Worn, damaged or dirty O-rings on valve assemblies. 

Clean and lubricate the valve assemblies and the
valve sleeve assembly.  Replace the O-rings on the
valve assemblies if necessary.
