TROUBLESHOOTING, Continued
#6 CONDITION: The tool stops tensioning before maximum tension is reached, but the air
motor continues to run.
CAUSE
This is an indication that the clutch and drive gear
teeth are worn through normal use, or the clutch and
drive gear teeth are worn due to improper tool usage,
i.e., activating the eccentric handle before stall-out
occurs during the tensioning cycle. Refer to
Operating Instructions for proper tool usage.
#7 CONDITION: A poor weld identified by an incomplete area of weld.
CAUSE
The grippers have become clogged with strap residue
or the bearings in the weld mechanism are extremely
dry. Welding is achieved by a combination of
vibration and downward pressure of the upper
gripper. Either a restriction of motion or a reduction
of downward pressure will cause a poor weld.
#8 CONDITION: Incomplete or no weld.
CAUSE
1.
Improperly set weld time adjustment.
2.
Worn teeth on upper or lower gripper.
3.
Insufficient air supply pressure.
4.
Worn pressure eccentric or bushing in weld
housing.
5.
Worn slider link.
#9 CONDITION: Strap is over welded.
CAUSE
Improper weld timing adjustment.
#10 CONDITION: Motor shutoff is sluggish.
CAUSE
Air leakage in the timing circuit.
REMEDY
These parts must be replaced. See Parts Removal
and Replacement Section.
REMEDY
Dismantle and clean the weld mechanism by brushing
away the strap residue or washing the entire unit in a
solvent. When a solvent is used it is imperative the
assembly be blown dry to remove all solvent. Check
for dry or worn bearings in the slider link and gear
housing. Replace or lubricate as required. If the tool
has been used extensively, examine the teeth on the
upper and lower grippers for wear. Replace if worn.
Lubricate the weld mechanism with Mo-Lith #2 grease
and reassemble.
REMEDY
1.
Adjust weld time as required per instruction in
this manual.
2.
Replace as required.
3.
Remedy as required.
4.
Replace as required.
5.
Replace as required.
REMEDY
Decrease weld timing as needed.
REMEDY
Check air lines and fittings for leaks.
