EMI Safety Information

EMI Warning

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 devices 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.

Ignition

Place your keys in the ignition and turn clockwise one click to engage the motor. You will know the scooter is on once the LEDs light up on your control panel. To turn off your scooter, simply turn your key counter-clockwise.

Operating Levers

The forward lever is on your right hand and the reverse lever is on your left hand. The speed of the scooter is determined by the amount of pressure applied to these levers. Either lever is capable of both forward and reverse operation.

Brakes

The scooter uses electromagnetic brakes assisted by the motor to provide a smooth, comfortable stop. To use the brakes, simply release the operating levers, and the scooter will automatically engage the brakes.

Operating Controls

For emergency stopping situations, the Emergency Brake Button can be pushed for maximum braking at any speed. When this control is used, the key must be turned off and then back on to re-set the breaker.

Hi/Lo Speed Switch

This switch is used to select one of two speed settings, which can be used in conjunction with the speed adjustment knob for infinite adjustment.

Speed Controls

You can adjust the speed of your scooter by turning the speed adjustment knob. The lowest setting is achieved by turning the knob fully counter-clockwise; the highest setting is achieved by turning the knob fully clockwise.

Charge Indicator

The number of LED bars lit indicates the amount of charge left; this is a true battery remaining indicator.

Light Switch

This switch turns the headlights and taillights on or off. 'I' is the 'on' position and 'O' is the 'off' position.

Horn

The horn button is located on the tiller, facing the operator. Pressing the horn button operates it.

Horn/Audio Warning Level Control

The knob located above the cup holder controls all "Beeps" and audio levels, i.e., back-up alarm and turn signal warnings.

Direction Indicator Switch

The indicator switch engages the indicator respective to the position the switch is set to. Pressing up (labeled ◀️) engages the left indicator, and pressing down (labeled ➡️) engages the right indicator.

Charging and Operation

Charging Port

Turn the cover, and the charging port will be exposed. Align the charging plug's pins with the charging port's holes and gently insert the charger.

IMPORTANT! When charging your scooter, always make sure that you plug the charger into the scooter before plugging the charger into the wall! Failure to do so can potentially damage the scooter.

Brake Release Button

While the scooter is on, pressing the brake release button will release the brakes, allowing you to physically push the scooter forward and reverse regardless of the free wheel lever's position. Once the button is released, the brakes will automatically reengage.

Free Wheel Lever

The free wheel lever engages the parking brake while the scooter is inactive. Releasing the free wheel lever will allow you to physically move the scooter, but you will not be able to operate the scooter. For safety purposes, the lever should be left engaged.

• To release the wheels, push the free wheel lever up ⬆️.
• To engage the brakes (and for normal operation), push the free wheel lever down ⬇️.

WARNING! Do not put the scooter into free wheel mode on any grade of incline! The brakes will not be engaged in free wheel mode, and therefore the scooter can roll in an undesired manner and can result in injury or damage to the scooter.

Anti-Tip Wheels

The anti-tip wheels are a safety measure that helps to prevent the scooter from being tipped over. The anti-tip wheels are located at the rear of the scooter's frame.

WARNING! The scooter should never be used unless the anti-tip wheels are in place. Failure to do so can result in injury or damage.

Safety Warnings

WARNING! Failure to follow these instructions may result in damage to the scooter or personal injury!

Getting Started

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.

Before First Use

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 armrest 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.

Operation and Handling

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.

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 sharper 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.

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.

Extra Guidelines

Ramps / Slopes

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.

Adjustments

Tiller Angle Adjustment

The Tiller Adjustment Wheel is located on the side near the bottom right of the tiller. To adjust the tiller angle, hold onto the handlebar with one hand to support its weight, turn the wheel anti-clockwise to loosen the tiller, and adjust the angle of the tiller to the desired position. When you are comfortable with the new position, tighten the wheel by turning clockwise.

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 the bottom of your seat to the right-hand side where your right 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.

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 its original position. To do this, simply 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 not be over-tightened.

Seat Tilt Function

The seat back cannot be reclined, but it can be tilted forward for storage. Simply push the seat down until it is flat against the seat pan.

Seat Removal

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 where the seat is mounted. 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.

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.

Seat Height Adjustment

It is recommended that the scooter is returned to Daymak for all seat height changes, as the mechanism must be adjusted to the correct torque to ensure safe use.

Disassembling the Scooter for Transport or Storage

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:

1. 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" section for more information.
2. 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!

Batteries and Charger

The Boomerbuggy series utilizes two maintenance-free, sealed lead acid batteries. Battery performance is affected by various factors including: temperature, terrain, the weight of the user, and overall usage. 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.

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.

Maintenance and Troubleshooting

Lubrication

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.
