OWNER’S MANUAL
02.
While most rowing machines imitate the action of rowing, they do so
mechanically, and therefore lack the natural dynamics experienced when a boat
and crew glide down a river.
At WaterRower, we have focused on replicating the physical dynamics of rowing,
with the knowledge that this will achieve all of its physiological benefits, as well
as much of the aesthetic pleasure.
To maximize the enjoyment from using your WaterRower we recommend that you
follow our suggestions on rowing technique and training programs. We hope that
some of the discussion points in this manual will improve your knowledge about
exercise in general, so that you are better able to fulfill your specific exercise
objectives.
Your WaterRower has been carefully hand-crafted to give you years of trouble-
free use. You will notice that each WaterRower is unique due to the variance in
color and grain that occurs naturally in genuine hardwood. We recommend that
you closely follow the assembly details provided, particularly by assembling the
machine in the correct sequence, and adhering to the suggested maintenance
schedule.
We hope you enjoy using your WaterRower for many years to come!
“Rowing, indoors or outdoors, at any exercise level of intensity, requires a greater
exercise expenditure than any other aerobic activity. Calories are burned in relation to
the number of muscles used and the intensity and duration of the exercise. Rowing with a
sliding seat uses a very large muscle mass since the upper, lower and trunk muscles are
used vigorously.”
- Dr. C. Everett Koop- Former US Surgeon General

SAFETY
We recommend consulting a physician before starting out with an exercise
program. Please read all instructions before using the WaterRower. Additional
information on getting started, rowing technique and rowing training advice can
be found at www.HowToRow.com.
CAUTION:Please keep hands away from moving parts when rowing machine is
in use. Failing to do so can lead to injury. For further information on safety tips,
please refer to:
www.waterrower.com/safety.
OPERATION
The WaterRower is unique in using the effect of drag to provide an exercise which
is entirely self paced. Because drag is linked to speed, a crew rowing down a
river chooses its intensity of exercise simply by altering the pace at which they
row: the faster the boat travels the greater the drag and the harder the crew
must work. There is a similar effect in swimming.
By replicating these dynamics the WaterRower does not require adjustment to
increase resistance: if a more intensive workout is required, simply row faster
and harder, and the WaterRower will respond accordingly.
WATER LEVEL
The amount of water in the tank simulates the weight of the boat and crew as it
glides down the river. Changing the water level does not change the resistance, it
simply changes the mass which the user is trying to move. Increasing the water
level simulates a heavier boat and crew mass, similarly reducing the water level
simulates a lighter boat and crew mass.
The water level is adjusted according to one’s personal preference or user type;
the intensity is altered simply by moving the chosen mass faster or slower. A
level gauge is positioned on the side of the tank. Overfilling the tank could impact
the warranty coverage. Do not fill above the maximum level.
Note: Fill the tank with ordinary municipal water. Municipal water contains additives which
will deter the growth of algae. If municipal water is unavailable, use distilled water (do
not use well water). Unless using blue dye, add the purification tablet supplied with your
WaterRower. Refer to the section on Preventative Maintenance for advice on keeping the
water clean and clear.
FOOTPAD POSITION
The Footpad has been designed to be adjusted for maximum
comfort. The Footstrap is designed to cross the foot at the
pivot point of the toes (the ball of the foot). This should enable
the heel to be raised off the footboard as the user comes
forward with each stroke. The Footpad can be easily adjusted
to accommodate different users, simply lift the top lip of the
Footpad to unhook and slide up or down to reposition on
another hole.
START UP MAINTENANCE
During the first weeks of use, your WaterRower will adjust to use and the
temperature/humidity of the environment. During this period we advise that you
GENTLY tighten all the connecting bolts with the 5mm ratchet supplied. Please be
careful not to overtighten any of these bolts.
Additionally, as the drive and recoil belts loosen up with use, it may be necessary
to tighten the bungee cord. To do this, leave the handle in the full forward
position and adjust the bungee/recoil belt buckle to provide a little more tension.
It may be necessary to tighten to perform these two simple start up procedures
once or twice over the first month of use. Please refer to Adjusting the Recoil
video at:
www.waterrowerservice.com/videos
PREVENTATIVE MAINTENANCE
Periodic maintenance is required to maintain the condition of the water in the
tank. We strongly ADVISE USING MUNICIPAL TAP WATER which contains
treatments to keep it free from bacteria and algae, etc. The water must be
refreshed periodically by adding a Water Purification Tablet provided (if using the
blue dye, do not use the purification tablet). The purification tablet degrades by
exposure to light: this may vary from 6 months in direct sunlight to 2 years in an
artificially lit environment. Generally we suggest adding one purification tablet
every 6 months.
If water discoloration occurs, add a purification tablet immediately. If the water
does not clear, we recommend emptying the tank, flushing it out with clean
water, refilling and adding a purification tablet. NEVER USE POOL CHLORINE OR
CHLORINE BLEACH in the tank as this will irreparably damage the polycarbonate
tank. The use of an alternative purification option in the tank beyond the approved
WaterRower product could void the warranty.

WATERCOACH
WaterCoach is a rowing education program designed to broaden the knowledge
of rowing as a fitness pursuit. WaterCoach consists of three rowing education
programs for the WaterRower owner, fitness professional/instructor and the
general rowing machine user in the gym:
• WaterCoach Home - personal training advice for the WaterRower owner.
• WaterCoach Professional - a rowing education program for the fitness
professional/ instructor. ACE certified course.
• HowToRow - for the rowing machine user, at a gym.
We hope that this expanded knowledge enables you to realize the unrivalled
physical benefits of rowing and get the best from your WaterRower. For more
information, please visit www.HowToRow.com.
YOUR EXERCISE PROGRAM
Most of us recognize the benefit of exercise and the potential improvements
to our general health and well-being. However, few of us fully understand the
physiology of exercise and the best means of achieving our specific exercise
objectives.
In order to get the most out of any exercise program, it is essential to have an
understanding of what your exercise objectives are. These may include reducing
or maintaining weight, improving general strength, developing bulging muscles,
improving sporting competitiveness or simply avoiding the health consequences
of a modern sedentary lifestyle. It is important to set a few different types of
objectives.
CATCH POSITION
Sitting tall, arms straight reaching
forward, shoulders relaxed, head up, eyes
looking forward, legs compressed and
shins vertical.
DRIVE PHASE
Drive back with the legs, arms hang off the
handle and only begin to bend once handle
is above the knees, torso is strong with
good posture and body angle opens up
slowly as you drive the legs.
RELEASE POSITION
Legs straight, handle drawn to chest,
sitting back just past the vertical, torso
firm, shoulders relaxed, head up and eyes
looking forward.

MAINTAINING AND CLEANING
To maintain the appearance and integrity of your WaterRower it is necessary to
keep the machine clean. It is particularly important to ensure that there is no dust
build up in the clutch and belt mechanism between the top and bottom decks.
Dust can be removed by using a cloth or vacuum cleaner.
The surface of the Rails must be kept clean to prevent dust and dirt from
deteriorating the Seat Wheels; the rails can be cleaned by wiping with a damp
cloth. The surface of the tank can be cleaned, however, please ensure you read
the instructions for any cleaning fluids prior to use: do not use methylated
chlorates or ammonia based fluids.
DO NOT USE METHYLATED SPIRITS, CHLORATES, BLEACH OR AMMONIA BASED
FLUIDS WHEN CLEANING ANY PART OF YOUR WATERROWER. The use of
improper cleaning products could void the warranty.
MAINTAINING THE FRAME
The metal surface can be wiped clean with a damp cloth and a small amount of
nonabrasive cleaner can be used. We do not recommend storing the WaterRower
outside. The use and/or storage of the WaterRower in inclement weather,
including, but not limited to, extreme temperatures and moisture could void the
warranty.
STORAGE OF YOUR WATERROWER
Your WaterRower can be stored upright. Lift the rear leg end, pull the
WaterRower towards you and use the momentum to stand it in an upright
position. When storing the WaterRower, please ensure the seat is in the forward
position (close to the footboard). When stored upright the WaterRower is stable
and it only takes the space of a chair.
USING YOUR WATERROWER
The Rowing Action uses 84% of your muscle mass; from the tips of the fingers
holding the handle/oars, to the balls of the feet connected to the footboard/boat,
all the muscles between these 2 points contribute to the Rowing Action.
The Rowing Action is comprised of both fast (drive phase) and slow (recovery
phase) movements. It is important to combine these 2 movements into a rhythm
in order to create a smooth, flowing, unhurried Rowing Action. The following
diagrams show 3 basic movements of the Rowing Action.
Allow yourself the first few rowing sessions to practice the correct positions and
phases as well as the correct ratio and rhythm of the rowing action. With regular
rowing, the technique will become easier and you will soon experience the
physiological benefits of rowing.
Please visit www.HowToRow.com to learn more about rowing technique.

07. 08.
These are divided into:
• Immediate Objectives - weekly
• Short Term Objectives - monthly
• Long Term Objectives - yearly
Your long term objectives are your final objectives. To achieve these, you need
stepping stones which are the short term objectives and immediate objectives.
Objectives need to be:
• Specific - set goals that you would like to achieve by certain dates
• Realistic - do not set a standard too high or motivation will be lost
• Flexible - be prepared for set backs such as injuries and illness
WEIGHT MAINTENANCE
At lower intensities, our body uses a mixture of fat and carbohydrates as its
source of fuel. As the maximum aerobic output is approached, the percentage
of fat consumed as fuel reduces to zero. Also, as the duration of exercise is
increased, the percentage of fat consumed tends to increase.
If your objective is weight maintenance, then the energy (food) you consume must
equal energy used (exercise, metabolism etc.). Exercising for weight maintenance
is best achieved at lower intensities and over longer durations. A low intensity
(60 - 70% of the maximum heart rate) is typically that at which you can hold a
conversation; it is by no means strenuous and is about that achieved by a brisk
walk.
AEROBIC TRAINING
A sustained exercise program will improve the efficiency with which the
respiratory and cardiovascular system can supply oxygen. This improves lung
function, heart function, vascular efficiency and capillary growth, leading to
improved well-being and endurance. At about 70 - 80% of the maximum heart
rate, lactic acid begins to accumulate in the blood supply at a greater rate than
it can be extracted by the liver, kidneys and other organs. Exercising above this
intensity will cause progressive accumulation of lactic acid in the blood, increased
heart and breathing rates and cause muscle fatigue.
Prolonged exercise at or below this intensity will maintain lactic acid at non-
fatiguing levels and exercise duration will be limited solely to the depletion of
available fuel stores. If your exercise objective is aerobic training (cardiovascular/
endurance), then it is necessary to exercise at an intensity which will avoid fatigue
due to lactic acid build up. This is best achieved at moderate levels of intensity
over medium/long durations.
A moderate exercise intensity (70-80% of the maximum heart rate) is about that
achieved by a steady jog, avoiding the onset of muscle soreness.
ANAEROBIC TRAINING
Anaerobic training causes the build-up of lactic acid (as rapidly as one minute
after exercise is commenced). Lactic acid saturation will necessitate either a rapid
reduction in exercise intensity or complete cessation.
The accumulation of lactic acid limits the contribution of the anaerobic process
to total energy production. Though energy may be generated rapidly, total work
capacity and total output is limited.
The level of intensity at which lactic acid begins to accumulate can be altered by
training. This is best done by improving the efficiency of the aerobic process and
is achieved by training at moderate levels of intensity.
Exercising at anaerobic intensities may condition an athlete’s tolerance to fatigue,
but the benefit can be more psychological than physiological. Prolonged exercise
at high intensity not only impairs the weight reduction and aerobic training effect,
but the rapid onset of fatigue can cause poor technique and increase risk of injury.
Training anaerobically is done at high intensities (80-100% of the maximum heart
rate) over a short period of time (10 seconds to a few minutes). Interval training is
a form of anaerobic training.
TRAINING GUIDELINES
To ensure you get the maximum benefit from training on your WaterRower and to
avoid unnecessary problems or injuries, here are a few guidelines:
• Consult your doctor before starting an exercise program.
• Use heart rate to monitor your intensity.
• Always warm up and cool down.
• Always stretch, especially at the end of your workout.
• Keep a record of your workouts.
• Keep well-hydrated.
• Gradually increase the intensity, duration and frequency of your workouts.
• Ensure you include recovery time in your training program.
• Add variety to your workouts. (Refer to www.HowToRow.com/workouts).

ADJUSTING RECOIL BELT TENSION
Make sure the recoil belt is properly tensioned:
• The recoil belt is too tight if the bungee is resisting you at the back of your
stroke (when you are farthest from the tank)
• The recoil belt is too loose if there is slack during the recovery phase of your
stroke (when you are coming forward toward the tank)
Adjusting the recoil belt is simple:
1. Rest the handle as far forward as possible (resting against the forward
riser cap).
2. Unclip the recoil belt from the bungee cord.
3. Adjust the recoil belt using the ladder lock buckle of the belt.
To increase tension, shorten the belt. To reduce tension, lengthen the belt.
