MAINTENANCE INSTRUCTIONS
MAXON electro-mechanical valves are endurance tested
far in excess of the most stringent requirements of the
various approval agencies. They are designed for long life
even if frequently cycled, and to be as maintenance-free
and trouble-free as possible. A valve operational test
should be performed on an annual basis. If abnormal
opening or closing is observed, the valve should be
removed from service and your MAXON representative
should be contacted. (See Technical Document
Maintenance of MAXON Shut-Off Valves 10-35.1. at
www.docuthek.com)
Valve leak test should be performed on an annual basis to
assure continued safe and reliable operation. Every
MAXON valve is operationally tested and meets the
requirements of FCI 70-2 Class VI Seat Leakage when in
good operable condition. Zero leakage may not be
obtained in the field after it has been in service. For
specific recommendations on leak test procedures, see
Technical Document Functional Testing of MAXON Shut-
off Valves 10-35.2 at www.docuthek.com. Any valve that
exceeds the allowable leakage, as set forth by your local
codes or insurance requirements should be removed from
service and your MAXON representative should be
contacted.

Actuator assembly components require no field lubrication
and should never be oiled.
Auxiliary switches, solenoids, motors, clutches or circuit
boards may be replaced in the field.
WARNING
Do not attempt field repair of valve body or
actuator. Any alterations void all warranties and
can create potentially hazardous situations.
If foreign material or corrosive substances are present in
the fuel line, it will be necessary to inspect the valve to
make certain it is operating properly. If abnormal opening
or closing is observed, the valve should be removed from
service. Contact your MAXON representative for
instructions.
Operator should be aware of and observe characteristic
opening/closing action of the valve. Should operation ever
become sluggish, remove valve from service and contact
MAXON for recommendations.
Address inquiries to MAXON. Local worldwide offices may
be located at www.maxoncorp.com. Include valve serial
