MAINTENANCE
Have qualified personnel do the maintenance work. Turn
the power off before working inside the machine. In
some cases, it may be necessary to remove safety
guards to perform required maintenance. Remove
guards only when necessary and replace them when the
maintenance requiring their removal is complete. Always
use the greatest care when working near moving parts.
If a problem cannot be corrected by following the
instructions, contact your local Lincoln Electric repre-
sentative for service options or contact Lincoln Electric
Customer Service.

Maintenance should only be performed by
authorized, qualified and trained persons
(skilled) using appropriate work practices.
When cleaning equipment or replacing
filter use personal protection equipment
(PPE) such as gloves, respirators and
protective clothing to protect against
overexposure to particulate. It is
recommended that a vacuum cleaner or wet methods be
used to clean up any loose particulate that is present in
the extraction arm. It is necessary to use a vacuum
cleaner with HEPA rated filtration.

Observe the maintenance intervals given in this manual.
Overdue maintenance can lead to high costs for repair
and revisions and can render the guarantee null and

During service, maintenance and repair jobs, always
use Personal Protective Equipment (PPE) to avoid
injury. This also applies to persons who enter the work
area during installation.

Always use tools, materials, lubricants and service
techniques which have been approved by the
manufacturer. Never use worn tools and do not leave
any tools in or on the product.
