FREQUENTLY ASKED QUESTIONS
The HAMMER-HEAD gives you maximum vacuuming power in a small, lightweight, portable package. That is what sets our
cleaner apart from conventional vacuum systems. Our 12-volt rechargeable unit has you cleaning immediately without the
usual set-up and run-around.
WHAT WILL IT DO?
Just lower it into the water and turn it on. The patented pressurized motor can entirely recirculate the average pool in under
an hour, and vacuum it clean in under ten minutes. Sand, sticks, leaves, and even coins are pulled into the high capacity
debris bag, reducing the number of filter cleanings. You'll use less effort, too.
WHAT WON'T IT DO?
Hammer-Head units equipped with a standard debris bag can vacuum up large leaves, coarse sand, sticks, mulch, small
gravel and even some coins. With a superfine debris bag (HH1508) or ultra-fine volcano bag (HH1510), you'll be able to pick
up almost all finer silt and dust. It will not filter algae out of the water, and it is not a complete substitute for the pool's
filtration system or filtration vacuuming. There will be cases where the filtration system is the best way to clean the pool. For
all other cases, however, the advantage to using the Hammer-Head is that the debris goes into the bag, it stays out of the
filter system. This means fewer filter cleanings, and less strain on the pool equipment.
WHY WOULD I WANT TO USE ONE?
Hammer-Head can help you increase your profitability. In the pool business, time is definitely money, and the rapid setup
and working speed of the Hammer-Head unit will cut your pool vacuuming time by as much as 50%. If your goal is to shorten
your workday, or if you want to take on more work, you will save time with a Hammer-Head.
What is your time worth to you? In the maintenance business, time really is money, and any tool that saves you time is an
investment in your own profitability. Faster cleaning times means more pools can be serviced in a day, leaving time for repair
work or opening new accounts. Your Hammer-Head will pay for itself in time savings alone and will leave you wondering
how you ever got by without one.
DO I HAVE TO BE TRAINED TO OPERATE IT?
A Hammer-Head isn't that much different than your household vacuum cleaner. The cart is balanced, rolls easily over most
terrain, and carries most of what you need in one trip. You'll expend less energy on the job. Just attach a standard pool pole,
lower it into the water, and turn it on. It's that easy.
IS IT SAFE FOR VINYL LINER POOLS?
Yes. The Hammer-Head vacuum head has over 1" of clearance from the pool bottom, so scuffing or tearing a liner is not an
easy thing to do. And because the Hammer-Head vacuum head design has wheels on the outside of the head, they protect
it from making contact with the liner. The Hammer-Head suction is very powerful, but it can't lift the liner off the bottom
because it's not close enough to it. We also make a brush attachment for the 21" head that lifts the vacuum off the bottom on
firm brush bristles. It will change the steering, but raise the clearance even more.
WHAT IS THE MINIMUM WATER DEPTH?
Hammer-Head cleaners operate in any water depth greater than 12 inches. The debris bag does not have to be fully
submerged for the vacuum to work, but the propeller on the motor must be underwater. Hammer-Head vacuums do not
vacuum on dry land.
IS IT SAFE TO VACUUM WHILE SWIMMERS ARE IN THE WATER?
The Hammer-Head uses safe 12 volt DC power to operate. Although it is easier to vacuum a pool when there are no
swimmers present, there is no electrocution danger to swimmers when the Hammer-Head is battery powered and in use.

HOW DOES IT MOUNT TO MY TRUCK OR TRAILER?
The SERVICE-21 mounts to any truck equipped with a 2" REESE type hitch receiver. It mounts to any trailer with a set of U-bolts
(included). The cart is secured to the mount with a toggle clamp latch and a safety pin. The Resort-30 and Resort-21 units use
different carts and do not mount.
CAN I GET A RESORT-30 UNIT THAT CAN MOUNT?
No, but... Some prefer the larger head and longer cord on the RESORT-30, but need a portable unit for their daily pool route, so we
offer the SERVICE-30 as an alternative. It has the longer cord (60') and larger head (30") and also includes the mount system.
WHAT IS THE DIFFERENCE BETWEEN THE RESORT UNIT AND THE SERVICE UNIT?
The Resort units and Service units both use the same motors and the same interchangeable parts. The main difference between the
two is in the cart design. Our service units are designed for pool to pool service route work and are ready to mount on your truck or
trailer. Resort units are designed for maintenance work where the unit will be left on site, and are not compatible with the vehicle
mount assembly. Resort-30 units have been used by aquatic facility managers around the US and abroad. Disney Resorts, Sea
World, the US ARMY, the YMCA, cruise lines, countless country clubs, condominium associations, and municipalities have relied on
the portability and ease of use that make the Resort-30 and Resort-21 the only economical equipment choice.
IS THERE A WARRANTY? CAN I GET PARTS?
Hammer-Head units are backed by a limited one year warranty (12 months upon registration, or 6 months if the unit is not registered)
and we offer a full compliment of readily available parts through your dealer/distributor, and service through Hammer-Head to keep
your cleaner's motor working smoothly year after year. Click here to download our warranty statement.
CAN I JUST PLUG IT INTO A WALL SOCKET?
NO. The HAMMER-HEAD is designed to accept a 12 volt deep cycle marine battery as a power source (not included), and the use of
any other power source is not advised. Attempting to use any other power source can damage the unit and/or put you at risk of
electric shock. You can use any 12 volt battery of any size, but typically, the bigger the battery, the longer the run time. Deep-cycle
batteries are the only batteries that will last. It is possible to run the Hammer-Head using a 110 volt AC to 12 volt DC converter, we do
not recommend operating the unit in this way due to the higher risk of electrocution. Please call to discuss the necessary
specifications using a converter.
WHAT KIND OF BATTERY AND CHARGER WILL I NEED?
We suggest the use of a 12 volt deep-cycle marine battery and an automatic charger that can charge at a minimum of 6 amps and no
more than 10-12 amps. Charge your battery every day. DO NOT TRICKLE CHARGE. DO NOT USE A CAR BATTERY.
Marine batteries typically come in series sizes 24, 27, and 30. We suggest a series 27 size battery. The bigger the battery, the longer
the run-time. Avoid marine starting batteries. A general purpose trolling motor battery will work fine. We do not recommend using
marine starting or cranking batteries due to their shorter life span. Sealed, or maintenance-free batteries are a good idea so you don't
have to check liquid levels. These items are available at super stores, marine supply stores, auto supply stores, and some buyer's
clubs. Make sure you charge your new battery before using it for the first time. Hammer-Head strongly suggests that you use a deep-
cycle marine gel battery for the best performance and longest life. For more information about gel batteries and chargers, visit
www.poolandmarine.com
WHAT IS THE NOCO CHARGING PORT FOR?
Hammer-Head units are equipped with a NOCO battery charging port, located just below the switch (NOCO part number GC016 or
Hammer-Head part number HH1902). When using the compatible NOCO charger (NOCO part number G7200 or Hammer-Head part
number HH1900 - not included), you can plug directly into the side of the unit for nightly charging. The NOCO charging port also gives
an LED readout of the battery charge level. TIP: After connecting to the port and plugging the NOCO G7200 charger into an
outlet for the first time, make sure you do the initial setup. Press the "MODE" button to select the proper voltage level
(12volts) and the battery type (in most cases select "NORM", unless you are using an AGM-type marine battery). Once you
have set up the charger, it will charge at the proper rate of 7.2 amps, bring the battery up to a full charge, and then maintain
it until you are ready to work again. Remember, the charger setup only has to be done the first time you use your NOCO
G7200 charger, after that, the charger automatically knows what to do. For best results and longest battery life, make sure your
Hammer-Head unit is always plugged in to your NOCO charger (or an automatic charger with a minimum charge rate of 6
amps) when not in use.

BATTERY USE AND LIABILITY
Thousands of Hammer-Head pool cleaning units are currently in use across the United States and in other parts of
the world. With proper care they will provide years of dependable service. Please review the following safety
information.
WARNING: IMPROPER BATTERY USE OR FAILURE TO INSPECT AND MAINTAIN YOUR 12 VOLT
BATTERY CAN RESULT IN SHORT CIRCUITS, DAMAGE DUE TO OVERHEATING, BATTERY
FAILURE, AND POSSIBLE FIRE OR PERSONAL INJURY.
THE OPERATOR ASSUMES ALL RESPONSIBILITY AND/OR RISK ASSOCIATED WITH THE USE OF
ANY HAMMER-HEAD PRODUCT, INCLUDING BATTERY SELECTION, INSTALLATION, USE, AND
MAINTENANCE. USE OF ANY POWER SOURCE OTHER THAN A 12 VOLT DEEP CYCLE MARINE
BATTERY IS NOT RECOMMENDED AND CAN VOID ALL WARRANTY OR LIABILITY CLAIMS.
•Wiring connections must be inspected daily. Wires that are hot to the touch indicate a connection problem and
should be repaired. Hammer-Head units that are not working properly should be either repaired immediately or
disconnected from all power sources and removed from service.
•Do not place anything in the battery box that can bridge the terminals on the battery - this can cause direct short
circuits and possible fire or even battery explosion.
•If you reverse the positive and negative wire connections on your battery, the motor will run in reverse and the
vacuum will suck the bag into the propeller. (If you have the HH1062 Smart Switch, the switch will not allow the unit
to run if the wires are reversed).
INSTALLING YOUR BATTERY

CORD CARE
•Poor power cord maintenance drastically shortens the
life of the motor assembly. Store the cord in large loops
as shown - Do not wind the cord up tightly.
•Avoid kinking the power cord or sucking it up into the
vacuum head.
•Avoid pinching the power cord in the mount assembly
when mounting the unit on to your vehicle.
•After vacuuming, remove any twists in the cord by
coiling the cord starting from the cart and ending at the
vacuum head. The head can roll across the deck on its
wheels, allowing you to take the twists out by spinning
the vacuum head before you put it on to the cart rest.
HOW CAN I KEEP MY SERVICE UNIT FROM BEING STOLEN?
Unfortunately, theft of Hammer-Head units is on the rise. The
easiest way to secure your cleaning unit is to put a padlock
through the mount ring on the cart frame (as shown here). If the
lock is in place, the cart can't easily be removed from the mount
assembly.
We also suggest using a locking hitch pin. (Hitch pins are not
included with the HH1300 mount assembly or with complete
Service-type cleaning units and cart assemblies.
MOTOR SAFETY & CARE
•Do not run the motor out of the water longer than three minutes.
•Do not attempt to remove or replace the bag or reach into the vacuum head while the motor is running.
•Hammer-Head units are very durable, but it is often better to scoop toys, rocks, sticks, or tree seeds out of the
pool before vacuuming to avoid jamming or breaking the propeller.
•Heavy piles of leaves can sometimes clog the vacuum. One way to clear clogs without stopping is to turn the
unit off and on a few times. (If you have the HH1062 Smart Switch, the motor will do this automatically three
times to clear the obstruction). You can also try raising the vacuum up to the surface and slightly out of the
water. When the vacuum sucks in a little air, it can loosen clogged debris so that it will pass into the bag.
•If the motor stops abruptly while cleaning, turn the unit off as quickly as you can to avoid damaging the unit.
(The HH1062 Smart Switch will prevent the motor from overheating in the event of a propeller jam). Some units
may also be equipped with a 30amp blade-type automotive fuse to prevent a motor overheat. If a motor jam
occurs on a unit equipped with a fuse, the fuse must be replaced before the unit will turn on again. (Spare fuses
can be purchased from any automotive parts supply store.
•Do not open the motor or disconnect the blue power cord from the motor assembly. Doing so voids the warranty
and exposes the motor to water damage.
•Motor/cord assemblies are sold through you dealer as a sealed unit. Damaged motors can also can be rebuilt.
