EMI Warning
EMI Safety Information
The increasing rate at which communication technology develops has
flooded our environment with electromagnetic (EM) waves that are emitted by
various sources (such as television transmitters, cellular phones, wireless
technologies, and etc). Electromagnetic Interference (EMI) occurs more intensely
as you approach the source of the transmission and are capable of causing your
scooter to malfunction or function uncontrollably. EMI may cause possible
interference with the motor and its braking system!
WARNING! Be wary of EM sources around you, as unintended EMI may cause
accident or injury! Some cellular phones and similar devises transmit signals
while they are on, even when not in use!
While not guaranteed, the following devices are not likely to cause emit
enough EMI to interfere with the scooter: cordless phones, laptops, AM/FM
radios, TV sets, CD players, cassette players, and small appliances.
EMI Recommendations
•Do not use hand-held personal communications (cellular phones, CB
radio, ham radio, walkie-talkies, etc) while the scooter is in operation
•Be aware of any nearby transmitters along your route to reduce
unwanted interference
•Turn off your scooter when not in operation to reduce chances of
unintended movement
•If unintended movement occurs, turn off your scooter as soon as it is
safe

SAFETY WARNING! When getting on or off the scooter, please make sure that
the key is in the off position to prevent engaging the scooter accidentally. When
seated comfortably, set the speed control knob according to your driving ability.
We recommend that you keep the speed at the lowest setting (fully counter-
clockwise) until you are comfortable with higher speeds.
Getting Started
Before the first use, you must charge your scooter completely. This should take
approximately 8 to 12 hours. Please refer to the Getting to Know Your Scooter
section for information on how to charge your scooter.
Getting On/Off
Before getting on or off your scooter, always make sure that the keys are not in
the ignition and that the scooter is off. This is a safety measure to prevent any
unwanted injury due to accidental engaging of the levers.
For easier mounting or dismounting, lift one of the arm rests before getting on or
off. Return the arm rest to its normal position before operation. Before operating
your scooter, ensure that you are seated in a comfortable position.
IMPORTANT! Do not use the handlebars or the tiller when mounting or
dismounting the scooter. For support, please use the arm rests!
Operating Instructions
Before going on your first trip, spend some time to practice handling your scooter.
Find an open area with plenty of room and no obstacles around. It is
recommended that you have a friend or family member assist you until you are
comfortable to operate the scooter on your own.
Forward and Reverse
First, make sure you are seated comfortably. Put the key into the ignition and turn
the scooter on. You will know that the scooter is active when the LEDs light up on
the control panel. Set your scooter to the lowest speed possible. You may adjust
the speed once you are comfortable with operating the scooter.

Daymak Inc. · 130 Oakdale Rd · Toronto, ON · 416-749-2324 · 1-866-379-7779 · www.daymak.com
Start by gently squeezing the right lever. Gradually apply more pressure to the
lever and the scooter will begin to pick up speed. If you have set your speed to
the lowest, your top speed will be restricted.
Once you are in motion, gently release the lever and the scooter will smoothly
come to a stop. Repeat moving forward and braking a few times to get used to
the motion.
Next is to practice reversing. To reverse, gradually squeeze the left lever. Same as
before, the more pressure applied to the lever, the faster the scooter will move.
Practice reversing and stopping a few times to get used to the motion.
WARNING! Make sure that there are no obstacles, curbs, or angled slopes
behind you before reversing! Practice reversing to get used to judging your
environment.
Steering
Steering the scooter is effortless and simple. Before you begin your practice,
ensure that there are no obstacles in the way.
To steer, simply rotate the tiller (handlebars) to the desired direction; the more
you rotate, the more sharp the turn. Begin by slowly moving forward and steering
the tiller at small angles; gradually increase the angle for your turn to familiarize
yourself with the maximum turning radius.
Practice by making gentle “S” patterns in both forward and reverse as much as
necessary.
When steering through limited spaces (such as a doorway or hallway), make sure
to mind the width of your scooter. When approaching doorways, take your time
and proceed slowly to prevent injury to yourself or others or damage to the
scooter.
When turning around corners, always keep a safe distance from the wall you are
turning towards. Most importantly, you want to ensure that your rear tires will
clear the corner without getting caught.

Daymak Inc. · 130 Oakdale Rd · Toronto, ON · 416-749-2324 · 1-866-379-7779 · www.daymak.com
WARNING! Never turn sharply while the scooter is at top speed! Always
exercise caution when taking corners. Failure to do so can cause injury and
damage.
Ramps / Slopes
Extra Guidelines
The stability of your scooter is governed by several factors such as seating
position, the angle of the slope, your height and your weight. Take caution when
approaching an incline and always head directly (perpendicular) to the slope and
not at an angle. While on the slope, avoid making any turns. When heading down
a slope, keep your scooter’s speed setting to slow.
Grass / Gravel
Your scooter was not designed to travel off-road and therefore caution should be
exercised when traveling on grass, sand, or loose gravel. If necessary, always
travel at a slow pace to prevent slipping.
IMPORTANT! You should never operate your scooter in wet weather or on wet
surfaces.

Adjustment
Tiller Angle Adjustment
The Tiller Adjustment lever is located
on the side near the bottom of the
tiller. To adjust the tiller angle, hold
onto the handlebar with one hand to
support its weight, pull the tiller
adjustment lever outwards and
adjust the angle of the tiller to the
desired position. When you are
comfortable, tighten the lever once
more.
IMPORTANT! Do not drive the
scooter if the tiller is not secured.
Seat Adjustment
You can adjust the seat to be either
closer or further from the tiller. The
seat adjustment lever is located on
your seat to the left hand side where
your left leg rests. To adjust your
seating distance, simply lift the lever
and adjust your seat accordingly.
Once released, the seat will
automatically lock into place.

Armrest Adjustment, Swivel Adjustment and Seat Removal
Swivel Adjustment
An alternative solution to mounting the scooter is to turn the seat outwards to sit
comfortably and then turn the seat back to original position.
To do this, simple pull the swivel adjustment lever outwards and the seat will
loosen. Adjust the seat appropriately and return the lever to its original position.
Armrest Adjustment
The armrests can easily be adjusted to be wider. To do this, turn the armrest
adjustment knob found behind the seat near the bottom counter-clockwise to
loosen the armrest. Adjust the armrest to the desired width and then retighten
the knob by turning clockwise. The knob should be not be over tightened.
IMPORTANT! Never operate your scooter without armrests securely in place.

Seat Removal Nut
The seat removal nut is located on the shaft holding the seat, next to the swivel
adjustment lever. This is a grub screw that engages a groove on the shaft that the
seat is mounted on. By loosening or removing this nut, you will be able to remove
the seat. Upon reinstallation, pay extra attention to ensure that the nut is secured
and in place.
Seat Removal
After you have removed the seat removal nut, the seat can be easily removed by
lifting the chair off of the shaft it rests on.
The Boomerbuggy series was designed to be easily dismantled for efficient
transportation and storage. Disassembling the scooter requires very little time
and effort. Simply follow these steps to disassemble your scooter.
Disassembling the Scooter for Transport or Storage
•First remove the seat. You can do so by loosening the swivel lever and
removing the grub nut that holds the seat to the shaft. Please refer to
the Seat Removal for more information.
•With the seat removed, release the tiller lever and fold the tiller all the
way down to where the seat used to be.
IMPORTANT! While disassembled, the scooter is still considerably heavy due to
the batteries and motor. When transporting the scooter, always have someone
around to assist you!

Daymak Inc. · 130 Oakdale Rd · Toronto, ON · 416-749-2324 · 1-866-379-7779 · www.daymak.com
The Boomerbuggy series utilizes two maintenance free, seal lead acid batteries.
Battery performance is affected by various factors including: temperature,
terrain, the weight of the user, and overall usage for the batteries. The battery
level indicator/gauge is only a guide for judging the amount of charge in the
batteries. The true charge of the batteries will display once the scooter is in drive.
Batteries and Charger
To optimize the battery life, only charge the scooter once the batteries are at
approximately 20%.
When storing your unit, be sure to charge the scooter at least once every two
weeks to optimize the battery’s life. Leaving the batteries completely discharged
can cause irreversible damage to the batteries and may need to be replaced.
Charger and Charging
To charge your scooter, first make sure that the bike is off. Plug the charger into
the charging port (refer to the Getting to Know Your Scooter section) and then
plug the charger into the outlet. Once connected, a red light should appear on the
charger; this indicates that the scooter is being charged. When the scooter is
completely charged, the charger will automatically terminate the charge and the
light will turn green.
The charger requires a minimum feedback voltage signal from the batteries in
order to begin the charging cycle. If your batteries are severely discharged for a
long period of time, the charge may not receive the necessary feedback and
therefore the batteries will not charge. If this occurs, contact your nearest
Daymak dealer for assistance.
IMPORTANT! Always insert the charger into your scooter before the outlet!
Failure to do so has a possibility of short circuiting the scooter.
IMPORTANT! Never let your batteries completely discharge. Doing so can result
in irreversible damage to the batteries.

Daymak Inc. · 130 Oakdale Rd · Toronto, ON · 416-749-2324 · 1-866-379-7779 · www.daymak.com
Lubrication
Maintenance and Troubleshooting
In six-month intervals, you should lubricate the following parts with multipurpose
grease or similar lubricant: seat pivot post and seat release lever.
CAUTION! Do not lubricate the transaxle gears!
Wheels and Tires
The wheels have split rims, which allows easy puncture repair. To change the
wheel, remove the center 13mm bolt and slide the wheel off its axle. When
refitting the wheel, be sure to use a locking washer and use locktite or a similar
adhesive. When changing a tire, the inner tube must be deflated. Remove the
four bolts from the wheel and split the rim.
General Maintenance
Every six months, you may need to tighten certain nuts and bolts. The reason for
this is due to the fact that operating the scooter will cause a lot of vibrations,
which can gradually loosen the nuts and bolts on the scooter. The following are
some areas that require attention: tiller base bolts, wheel axle bolts, armrest
adjustment bolts, wheel-to-axle bolts, and etc.
Troubleshooting Check List
If you are having trouble operating your scooter, please check the following:
•The unit is switched on
•All plugs and connectors are firmly fixed
•Battery is fully charged
•Free wheel lever is engaged
•Battery fuses are not blown
If the problems persist, try resetting the circuit breaker. The circuit breaker can be
found under the rear chassis cover and is accessible through a port hold under the
seat.
