5. SERVICE AND OPERATION DISTURBANCES
The amount of use and working environment should be taken into consideration when planning
the frequency of maintenance of Feed 420R and 120R. Careful use and preventive maintenance
will help to ensure trouble-free operation.
Following maintenance operations should be carried out at least every six months:
Check:
– Feed roll grooves. Excessive wear of grooves causes wire
feed problems.
– Wire guide tubes. Badly worn feed rolls and wire guide
tubes should be discarded.
– Wire guide tube in the gun should be set as close to the feed
rolls as possible and the wire must follow a straight line
from the end of the tube to the groove of the feed roll.
– Reel brake adjustment.
– Electrical connections:
* Oxidized couplings must be cleaned
* Loose couplings must be tightened
Clean dust and dirt from the equipment.
When using compressed air, always protect your eyes with proper eye protection.
In case of problems contact an authorised KEMPPI service workshop.
