epoxy systems. Under no circumstances should any acid or corrosive
chemicals be used in the unit. Consult GUSMER if there is any doubt about
the compatibility of the system to be used in this equipment.

caution to insure the gun or head is never pointed at or near any persons,
and that the head is never actuated with the outlet tip blocked or restricted
by any part of the body.
PERSONAL PROTECTION
The use of solvents and chemicals will be required when operating,
servicing or cleaning. To prevent excessive exposure to the chemicals and
solvents to which will be used when operating this equipment, appropriate
personal protective gear such as eye and face protection, respiratory
protection, and protective gloves and clothing may be required.
