MAINTENANCE SECTION
BEFORE ATTEMPTING ANY REPAIR OR MAINTENANCE OPERATION DISCONNECT TOOL FROM
THE POWER SUPPLY. USE OF PROTECTIVE GLOVES IS RECOMMENDED.
Other than those areas detailed below, we recommend that maintenance be limited to:-
•
Keeping the nozzle externally clean (by wiping after use and while still warm).
•
Periodic cleaning of the nozzle (to ensure smooth repair material application).
FOR OTHER REPAIRS CONTACT YOUR SUPPLIER.
REPAIR ROD “BACK UP”
This is when molten repair rod material is forced between the repair rod and inlet tube wall. It normally
occurs if the nozzle is blocked, or if the tool has been operated before having reached operating
temperature.
Remedy :- Allow tool to stand for a few minutes and try again. If nozzle blockage suspected clean nozzle.
“Back up” is normally self-clearing during normal operation due to the tool’s non-stick inlet tube.
If the tool has been switched off in a “backed up” state after previous use, it may show symptoms of slow
warm up, and may take a little longer than normal before repair material can be extruded
REPAIR ROD “BUNCHING “ AT INLET TUBE.
This will only occur when the tool is left unused for longer than the recommended time. To clear any
bunching, cut the repair rod as close to the inlet tube as possible. Remove the unused portion, reload with a
fresh rod and operate normally.
