Introduction - Sherwood Scuba maximus SRB5600 Assembly & Maintenance Manual

1.0 INTRODUCTION

1. The procedures in this manual apply to the Sherwood Scuba SRB5600 Maximus regulator
only. The older SRB3600 Maximus regulator has different parts and service procedures. The
SRB3600 has its own service manual. The correct service manual for the two models can be
determined by looking at the cover picture of the regulator. The most current part numbers can
be obtained by referring to the dealer price guide, or calling your Sherwood Sales
Representative.
Proper torque for the hose fittings is 40 in. lbs. (4.5 joules). NEVER tighten the hose fit-
ting to the first stage with more than 45 in. lbs. (5 joules) of torque. The inlet hose fitting
can be weakened by overtightening. Failure of the fitting could cause air loss resulting
in death, personal injury, or property damage.
All current Sherwood 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 for the Maximus is 4000-4. All other parts not contained in this kit must be
inspected by the technician and changed under warranty only if they have failed due to
problems with material or workmanship.
NOTE: Oxygen Enriched Air conversion kits are available for all current Sherwood regulators and valves.
The part number for the model covered in this manual is 4000-15N. These kits are to be installed into
properly cleaned and prepared regulators only by technicians trained by one of the major oxygen enriched
air training agencies.
2. This manual gives breakdowns of regulator parts, equipment specifications, servicing
instructions, troubleshooting recommendations, and guidelines for proper care of the SRB5600
Maximus regulator. This manual is intended for use only by persons specially trained and
authorized to service Sherwood Scuba equipment.
3. Anyone attempting to service or repair Sherwood Scuba regulators must have a thorough
understanding of the principles of operation of scuba regulators and valves, as well as the
appropriate 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 manual.
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 Sherwood.
5. Because of the many unique features found in Sherwood regulators, Sherwood conducts
seminars on a regular basis throughout North America to train technicians in proper service and
repair procedures for all current Sherwood regulators. In addition, all Sherwood 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 Sherwood regulators. For information on
the dates and locations of upcoming Sherwood service seminars near you, contact
Sherwood or your Sherwood Sales Representative.
