#3 CONDITION: The tool runs sluggishly.
CAUSE
1.
The air filter-regulator-lubricator is malfunctioning
or is not properly maintained.
2.
The tool may run sluggishly due to a clogged or
dirty motor filter screen due to a lack of properly
filtered air supply.
3.
The tool may run sluggishly due to an improper air
motor adjustment or a clogged or dirty vibrator
assembly.
4.
The end plates, pinion teeth on the rotor and the
rotor blades are worn, dirty or rusted.
#4 CONDITION: Feedwheel milling on strap and/or strap breaking.
CAUSE
1.
Feedwheel is clogged with dirt or strap residue.
2.
Worn teeth on the feedwheel.
3.
The bushing in the weld housing has worn because
of a lack of lubrication.
4.
Excessive or improperly set feedwheel to gripper
plug clearance.
5.
VXT-19 Break-in period performance change.
#5 CONDITION: The top strap is being properly tensioned but the tool does not hold the
bottom strap.
CAUSE
1.
The gripper plug may be packed with dirt or strap
residue preventing the teeth from penetrating the
strap.
2.
Worn teeth on the gripper plug.
3.
VXT-19 Break-in period performance change.
1A. Check the regulator to see that the correct air
pressure is getting to the tool.
1B. Check to see the filter unit is clean and
functioning properly.
1C. Examine the lubricator to see there is oil in the
bowl and that oil is seen dripping from the sight
dome as the tool operates. This assures the air
motor is being properly lubricated.
2.
Remove the Hansen plug at the inlet to the air
motor and examine the filter screen in the filter
assembly and clean it if necessary. See "Special
Instructions", page 9, on removing Hansen plug.
3.
Refer to Parts Removal and Replacement, Air
Motor, for proper motor adjustment. For clogged
or dirty weld assembly, see troubleshooting
remedy under "Welding".
4.
Carefully remove the air motor from the tool and
disassemble it. If these parts are only dirty,
clean, thoroughly oil and reassemble. If they are
worn or rusted, replace them.
1.
Clean teeth on feedwheel with the special brush
provided.
2.
Replace the feedwheel.
3.
Replace the bushing.
4.
Adjust feedwheel as required, see page 13,
Feedwheel to Gripper adjustments.
5.
Adjust the air motor as required, see "Strap
Tension" on page 7 of this manual.
1.
Clean the gripper plug with the special non-
metallic tool brush.
2.
Replace the worn plug. Since the feedwheel and
gripper plug are prevented from contacting one
another by an inside shoulder on each part, it is
not often these parts have to be replaced.
3.
Adjust the air motor as required, see "Strap
Tension" on page 7 of this manual.
