1.0 INTRODUCTION

1.0.1  The procedures in this manual apply to the Zeagle RaZor Valve/Regulator, the Envoy type 

2nd stage that comes attached to it, and the Filling Whip. Refer to the exploded views as you 

read the service section of the manual.  The Item Numbers referred to in the service section are 

those seen in the corresponding exploded view

 

 

! WARNING !

     NEVER tighten the hose fitting to the first stage with more than 40 in. lbs. (4.5 Nm) of torque. 

The inlet hose fitting will be weakened by over tightening. Failure to heed this warning may result 

in serious injury or death.

 

NOTE:

 All Zeagle Scuba Regulators have service kits available which contain the parts which 

must be changed at every annual service no matter what their condition.  The standard annual 

service kit part numbers are shown in the parts list.  All other parts not contained in these kits 

must be inspected by the technician and changed if necessary.  Parts will be handled under war-

ranty, only if they have failed due to problems with material or workmanship.

 

 

! WARNING !

 

 Zeagle Scuba Regulators are manufactured using materials suitable for use with oxygen 

enriched gases (i.e. Nitrox, etc.) providing the oxygen content does not exceed 40%.  Equipment 

intended for enriched air (Nitrox) use, must not be used with regular compressed breathing air 

or other gases. Regulators intended for enriched air use, can be serviced only by technicians 

trained by one of the major oxygen enriched air training agencies.  Failure to heed this warning 

may result in serious injury or death.

1.0.2   This manual gives breakdowns of regulator parts, equipment specifications, servicing 

instructions, troubleshooting recommendations, and guidelines for proper care of Zeagle regula-

tors.  This manual is intended for use only by persons specially trained and authorized to service 

Zeagle Scuba equipment.  

1.0.3   Anyone attempting to service or repair Zeagle Scuba regulators must have a thorough 

understanding of the principles of operation of scuba regulators and valves, as well as the appro-

priate mechanical ability.  The technician must be properly trained in the safe use of compressed 

air and the various tools and cleaning solutions involved in the procedures outlined in this manu-

al.

1.0.4   The best source for current part numbers for any of the parts listed in this manual is your 

current parts and price list from Zeagle. 

1.0.5   Zeagle conducts seminars on a regular basis to train technicians in proper service and 

repair procedures for all current Zeagle regulators.   In addition, all Zeagle dealers and their 

staff members are encouraged to attend the seminars to gain an in-depth understanding of the 

construction, special features and operation of Zeagle regulators.  For information on the dates 

and locations of upcoming Zeagle service seminars near you, contact Zeagle or a Zeagle Sales 

Representative.  Service Videos in various formats (VHS, CD, DVD, etc.) are also available.
