GENERAL TOWER CARE & MAINTENANCE
This product is to be used for the sole purpose of wakeboarding, wakesurng, hydrofoiling, and
kneeboarding.
The tower is intended to center tow a maximum of two wake boarders at one time and no more than
400lbs (181kg) collectively.
Check all tower hardware before every use on the water. We recommend keeping a set of allen
wrenches on your boat for this purpose. Verify that all bolts, screws, and nuts are tight. Even with
loctite they may loosen over time.
Never attach a tow rope to anything other than the tow head.
Do not use the board racks as entry/exit handles to get in and out of the boat – they are not designed
for this purpose.
Never hang from the tower or speakers. Do not climb or sit on the tower.
Be aware of the tow rope at all times. Ensure that it is not attached to anything on the tower other
than the tow head, and that the rope is clear of any cleats or objects on the boat before pulling the
rider up and out of the water.
Never travel at speeds in excess of 30mph / 48kph (i.e. towing the boat on a trailer) or
through extremely rough water with wakeboards, wakesurfers, skis, etc. In the racks.
Never travel at speeds in excess of 30mph / 48kph (i.e. towing the boat on a trailer) or
through extremely rough water with the bimini in it’s deployed state. ONLY travel with the
bimini in it’s folded state secured to the tower.
Be cautious when driving your boat on the water or on a trailer if you have board racks. They may
decrease your clearance into a garage or slip. Rotate board racks inboard.
Check the clearance between your tower and any overhead obstacles including bridges, canals etc.
NEVER USE CLEANERS ON YOUR TOWER OR ACCESSORIES! Your Roswell tower has been treated
with an automotive paint coating that forms a protective layer. A mild soap and water combination
may be used to remove traveling grime or water spots. Clean with each use. Use only a soft cloth and
never use any chemical cleaners. Treat as you would your vehicle. Wax to protect nish.

Tightening your Moomba Bimini Canvas
It is normal that your bimini canvas will stretch over time and use. Your Moomba
Bimini has been designed to allow you to tighten your canvas as needed.

Remove
this bolt
Remove the rear bimini arm bolts on port and starboard sides. Do not remove the front bimini arm bolts or
your fabric. Once both rear bolts are removed, re-apply Loctite to each bolt and re-thread them loosely
back into the tower. Have a friend lightly pull down on the bimini arms one side at a time. With the arm
being pulled down, re-tighten the rear bimini arm bolt. Repeat on the other side.
This method is best executed with 2 people

Tips and Tricks for your Bimini
It is normal that there is potentially a slight variation from one tower bimini to another.
Listed below are some tips and tricks to ensure that your bimini is installed and
functioning properly. This process is not mandatory for all biminis.
it is possible that once your bimini is installed your frame and
arms are not parallel where they pivot. This could make inserting
and removing your quick release pins difficult. If you are not
experiencing any issues, skip this page.
If your quick release pins are still difficult to remove and insert
with the addition of the arm shim washers, Roswell recommends
using a drill with a 5/16” drill bit to clean out the holes. Drill
perpendicular through the frame and bimini arms at the same
time. This will help with the alignment and ensure an accurately
aligned hole.

If your bimini looks like

need to add shim
washers between the
rear bimini mounts and
your bimini arms
Choose one side of your tower to work on first. Determine which
bimini mount the shim washers will need to be added to. Completely
remove the bolt that secures the bimini arm to your chosen bimini
mount. Loosen the other bimini arm bolt. Add the shim washer(s) in
between the chosen bimini mount and bimini arm (In some cases 2
washers may be required under each arm). Re-insert the bolt with
loctite applied. Remove the loosened bolt, apply Loctite and
re-insert. Tighten down the front and rear bimini arm bolts in the
same position they were in prior to loosening them. Repeat on the
other side of your tower.

• Always ensure your boards are securely fastened in place
by the rack. Give the board a quick tug to check it is secure
before setting off.
• Always ensure your swivel is properly locked before
moving your boat. Give the rack a tug and visually check
locking pin to make sure it is secure after you have put the
swivel in a new position.
• Never insert boards that are beyond the stated maxi-
mums and minimums for the rack:
• Always swivel your racks inboard when docking and/or
trailering your boat.
• Never trailer your boat with boards in the racks. Racks
are for on water use only.
• Check all bolts on the rack and swivel for tightness
before using your boat. If any bolts are found to be loose
remove them, apply red thread lock and re-tighten the
bolts.
• The driver should check their lines of sight before
operating the boat being sure nothing in the rack blocks
their safe view and operation of the boat.
• Be aware of your rope making sure it does not get
wrapped around the board rack, the boards, or any other
objects.

Narrow board setting
Wide board setting
Your Triton rack is designed to be adjustable
to fit just about any size of wakeboard,
wakesurfer or wakeskate. There are 2
settings, one for narrower boards, one for
wider boards.
In the narrow setting,
the max board width
should be no greater
than 20” inches and no
less than 14” inches.
In the wide setting,
the max board width
should be no greater
than 23” inches and
no less than 17”
inches.
Adjust your telescopic arms one at a time. To adjust your telescopic
arms loosen the knobs on both sides of the rack for the same arm
until the knobs are past the counterbored holes they sit in. At this
point you will be able to slide the whole arm assembly up or down to
the next position where you will then retighten the knobs.
Tighten
Make sure your adjustment knobs
are tightened periodically.
Inserting Boards
1 : Slide your board
into one of the
Triton rack slots.
2 : Pull up on the telescopic
arm and flip your board
towards it.
3 : Let the telescopic arm
clamp down over your
board.
To remove a board, repeat
steps 1-3 in reverse
Ensure wakeboards with sharper
edges are located within the harder
rubber wakeboard pads in the tine
slots. This is essential to avoid
damaging the softer foam protection
intended for fragile surfboards and
wakesurfers.
