Warnings
- Hollis Buoyancy Compensating Devices (BC's) are intended for use by divers who have successfully
completed a nationally recognized course in scuba diving and specically, the Katana Sidemount Har-
ness is for use only by persons who have also completed a recognized sidemount training course.
- Hollis BC’s must not be used by untrained persons who may not have knowledge of the potential risks
and hazards of scuba diving and sidemount diving.
- As with all underwater scuba diving equipment, improper use or misuse of this product can cause seri-
ous injury or death.
- Improper use of the oral ination/deation or dump valve assemblies may allow water to enter the BC re-
sulting in a subsequent reduction in buoyancy. Loss of buoyancy control could result in serious injury
or death.
- The Katana Sidemount Harness is designed for operating temperatures between 1° and 40° C.
- The Katana Sidemount Harness is limited to the use of two 15 L aluminum or smaller cylinders.
- The Katana Sidemount Harness is limited to a maximum operating depth of 130 ft / 40 meters.
- This is not a life jacket; it does not guarantee a head up position of the wearer at the surface.
- DO NOT depend on any Hollis BC to save your life under any circumstances.
- Prior to each dive, inspect and test your BC for proper operation. If any part does not function properly,
DO NOT USE!
- DO NOT inhale gases from within any Hollis BC.
- If you do not fully understand how to use your Hollis BC, or if you have any questions regarding its
functions, you should seek instruction in its use from your authorized Hollis dealer before you utilize
this product.
- Read and understand the owner’s guide completely before diving with any Hollis BC.
- Have your Hollis equipment inspected and serviced annually or any time you have any concern about
your equipment’s function or condition by an authorized Hollis dealer.
- Any questions or concerns may be directed towards your local Hollis dealer. Alternately, you may con-
tact one of our technical support representatives at 888-383-DIVE or [e-mail].
- It is the diver’s responsibility to assure that fully congured, ready to dive systems are able to achieve
neutral buoyancy at the beginning and end of any dive. Adding Non-Drop weights or switching from a
single cylinder conguration to sidemount (2 cylinder) conguration can add signicant in water weight.

OVERVIEW
This User’s Guide describes the unique functions and features of the Katana Sidemount Harness. The more
acquainted that you become with your new kit, the more you will enjoy your diving experience. By following the
instructions in this guide - you will understand how the Katana Sidemount Harness works, how to make best
use of its features, and how to ensure it is set up best for your needs.
All Hollis BC’s are constructed with the highest quality materials and utilize the latest computer aided design
and manufacturing techniques to ensure their top performance and reliability.
The Katana Sidemount Harness characteristics are ideal for sidemount cave divers but was designed for any
diver. Whether you are a beginner, advanced or a technical diver this kit was designed for you. The kit comes

twin or single cylinders. It may also be used with rebreathers or rear mounted single tanks. This system is suit-
able in any environment from open water to overhead.
SIDEMOUNT DIVING ADVANTAGES:

monitors all gauges, valves and hoses without assistance.
• Reduces additional gear – backplate / double bands / hardware / manifold - benet when traveling
• Aids in transporting gear to and from the beach or boat (two or one tank at a time). This includes exiting the
water on a boat dive.
•Streamlines prole which in turn reduces drag and energy which increases your bottom time

Attaching cylinders to the Katana Sidemount Harness
Katana Sidemount Cylinder Harness Kit. (Sold separately).
Kit includes the following (Fig. 1):
• SS Cam Bands – Qty 2
• SS Tri-Glides – Qty 2
• SS Bolt Snaps 4.5” – Qty 4
• Nylon Line (secures bolt snap to tank)
The image to the right shows how to secure the hardware properly
(Fig. 2). The top bolt snap is considered a “safety clip” or a redun-
dant point of attachment in addition to the bungee which wraps
around the tank valve. This clip connects to the shoulder D-ring
on both the left and right side of SMS harness. The lower clip is
secured using the cam band and tri-glide. It then connects to the
appropriate rail on the butt plate. Cam bands on both tanks should
be roughly ¾ the way down the tank as shown in the image.
NOTE: The lower bolt snap should be congured with the knot
facing towards the top of the cylinder as shown. This is
to provide additional security, preventing the knot from
pulling out of the tri-glide and 2" webbing.
NOTE: This is only a suggestion on how to congure your Ka-
tana Sidemount Harness Regulator Kit. There are other
congurations that you may nd better suit your diving
preference.

Final configuration
Your Katana Sidemount Harness comes pre-assembled which makes nal conguration much easier.
The last step is the adjustment of the harness is to ensure proper t when donning the harness. First tighten the
waist strap. This will help the following steps pull the harness tight against the body. Next, secure the sternum
strap to its appropriate length.
NOTE: Tighten the sternum strap just enough to keep the shoulder straps straight over the shoul-
der. DO NOT over-tighten which causes the straps to pull towards middle.
Finally, adjust the shoulder webbing. This should provide a rm and comfortable t. You may need to give the
sternum strap one nal tug once complete.
The wing retention system or “bungee” is used to keep the wing streamlined when not fully inated. It pulls the
excess material in while still allowing full ination. The bungee can be trimmed to the desired length. However
use caution as you may need this additional bungee length at a later date. Once trimmed it can not be replaced
without replacing the whole strap.
NOTE: Over-tightening will reduce the amount of lift in the wing.
Although preparation will take a small time investment, once you have completed the conguration steps (rigging
the tanks, attaching the cylinders, and adjusting the harness properly) your in water prole should look something
like below. Trim is horizontal and streamlined.
NOTE: Cam band more towards the rear or bottom of tank = Feet down / Cam band more towards the
front or top of tank = head down
Your training course outline will have specied alternate methods of achieving perfect trim.
