OPERATING CONTROLS
FOR DELTA TILLER
SECTION 7
1. KEY SWITCH - Insert the key and turn it clockwise one-quarter turn to turn on power.
The Battery Level Meter will move only when the key switch is on.
2. BATTERY LEVEL METER - This shows how much power is left in the batteries. The
batteries are charged when the needle is on the right hand side of the green area, and
low when it is in the red area.
NOTE: Battery condition should be checked when the Solo XT550 is stopped. While
operating, the needle will read lower.
3. HORN - Push button to sound horn.
4. VARIABLE SPEED SELECTOR - This controls the maximum speed you can travel.
Rotate the knob clockwise for higher speeds and counterclockwise for lower speeds.
Operate your Solo XT550 at lower speeds until you are familiar with how it handles.
Always use lower settings in confined or crowded areas. Faster speeds should not be
used except when traveling straight and in open areas.
NOTE: Reducing the speed setting also reduces power. If you are unable to climb a
ramp, you may need to turn the knob clockwise to increase power.
WARNING
Operating too fast for conditions can cause the Solo XT550 to tip over. This may
result in serious injury to yourself and damage to your Solo XT550. ALWAYS
REDUCE SPEED BEFORE TURNING AND WHILE OPERATING ON UNEVEN
SURFACES.

Accidentally bumping the Accelerator Lever while the key switch is on will cause the
Solo XT550 to move out of control. This may result in an accident, causing serious
injury or property damage. Do not turn the key switch on until you are securely
seated on the Solo XT550. ALWAYS TURN THE KEY OFF WHENEVER YOU ARE NOT
DRIVING THE SOLO XT550, EVEN IF YOU ARE SITTING IN THE SEAT. ALWAYS BE
SURE THE KEY IS REMOVED WHEN YOU ARE NOT SEATED ON THE SOLO XT550
TO PREVENT UNAUTHORIZED USE OR ACCIDENTAL MOVEMENT.

C24AB10
5. ACCELERATOR LEVER - The accelerator
lever controls both your speed and direction of
travel (forward or reverse). The Solo XT550
uses a “proportional” speed control system,
meaning the further forward you push the
Accelerator Lever the faster you will go, up to
the limit you have set on the Variable Speed
Control.
To go FORWARD, place both hands on the
handlebar and use your RIGHT thumb to push
the RIGHT hand side of the Accelerator Lever
ahead. (See Figure 11).
To go in REVERSE, use your LEFT thumb to
push the LEFT hand side of the Accelerator
Lever ahead.(See Figure 12).
Single Handed Operation. Your Solo XT550
can be operated with only one hand if
necessary. If only using the right hand, push
with the thumb to go forward and pull with the
index finger to go in reverse. If using the left
hand push with the thumb for reverse and pull
with the index finger to go forward (See figure
13 for right hand reverse example).
NOTE: If you must operate the Solo XT550 with your left hand only, the operation of the
Accelerator Lever can be permanently reversed for easier use. Consult your
Authorized ConvaQuip Dealer. THIS MODIFICATION MUST BE MADE ONLY BY
AN AUTHORIZED CONVAQUIP DEALER OR THE FACTORY.
6. POWER - The power LED indicates that the key is in the ON position, the Circuit
Breaker is not tripped and the batteries are correctly installed.
7. LIGHT (optional) - This switch turns the headlight and taillights on and off.

SECTION 8
Be sure you read and understand the Safety Instructions in Section 2 before attempting to
operate the Solo XT550.
1. Seat yourself securely on the Solo XT550, with the seat facing forward and locked in
the forward facing position. Use the armrest to aid in lowering and raising yourself from
the seat. The tiller is not designed for this purpose and it is considered misuse to use it
for this purpose.
2. Be sure both armrests are down and both feet are on the floor.
3. Adjust the steering tiller to a comfortable position and be sure it is locked in place.
4. Check position of Variable Speed Control knob. Always start in a lower setting.
5. Insert the key and turn the key switch on by rotating it 90° clockwise.
6. Check the Battery Level Meter to be sure you have enough power to get where you are
going.
7. Use the Accelerator Lever to go forward or reverse and to control your speed as
described in Section 7.
8. To stop, gradually release the Accelerator Lever, The faster you release the Lever, the
quicker you will stop.
9. Turn the key switch off when you stop, and remove the key when you get off.
As with many things, learning to safely operate a scooter is a skill that requires practice.
Ramps, inclines, and uneven surfaces require extra caution. Make sure you are familiar
with your Solo XT550 and comfortable with its operation and capabilities before attempting
these things.
WARNING
The Solo XT550 is an electrical device. DO NOT ALLOW THE SOLO XT550 TO GET WET!
√√
√√
√Do not spray with water from a source such as a garden hose or a pressure
washer. Take extreme care not to expose the electrical connections and
components to any moisture. Cleaning should be done with a damp cloth.
√√
√√
√Do not leave the Solo XT550 outdoors, uncovered, where moisture may contact it.
√√
√√
√Do not transport the Solo XT550 on the outside of the motor vehicle (such as an
open pickup bed, trailer, or outside mounted scooter lift) without an adequate
cover to protect it from moisture.
If the controller does become wet, do not operate the Solo XT550 for at least 24 hours or
until it has had adequate time for the unit to dry thoroughly. Operating the Solo XT550 or
energizing its electrical components while wet can damage the components and create
hazardous operation conditions.
CAUTION
If the Solo XT550 becomes stalled and does not move after applying full power for five
seconds, release the Accelerator Lever immediately. Continuing to apply power while
the Solo XT550 is not moving can cause severe damage to your electrical system.
CAUTION
Do not reverse directions while the cart is moving. Doing so will cause a very
sudden stop and may cause you to lose control or tip over. It may also damage the
electrical system of your Solo XT550

C24AB12
BRAKE SYSTEMS
SECTION 9
Your Solo XT550 uses two systems for braking, both of which are designed for automatic
operation. When you release the Accelerator Lever, the DYNAMIC BRAKE quickly and
safely brings you to a stop. After you are stopped the PARKING BRAKE automatically
comes on to keep the Solo XT550
from rolling. The PARKING
BRAKE also helps to stop you
when operating on a ramp or
incline.
The PARKING BRAKE is
engaged by spring pressure. It is
automatically released by an
electromagnet whenever you
move the Accelerator Lever. In
the event of a malfunction which
causes a loss of power, the
PARKING BRAKE will
automatically engage. A
MANUAL RELEASE LEVER is
provided which will release the
brake and allow the Solo XT550 to
be pushed. Simply pull up on the
lever (fig 14) to release the brake.
Push down to operate the Solo XT550.
When the MANUAL RELEASE LEVER is in the “released” position, a safety interlock
switch prevents the Solo XT550 from being driven. Do not leave the brake lever in the
“released” position when the Solo XT550 is unattended. A small amount of current is
required to power the interlock relay (even with the key switch off) which could eventually
drain the batteries.
WARNING
Never attempt to operate the Solo XT550 with the MANUAL RELEASE LEVER in the
“released” position. If the safety interlock is not functioning, you will be driving the
Solo XT550 with no PARKING BRAKE. This could result in an accident if operating
on a ramp or incline, causing serious injury and damage to property. Always be sure
the manual release lever is in the “drive” position before operating the Solo XT550.
Figure 14

C24AB13
BATTERIES
SECTION 10
The Solo XT550 is powered by two 12 volt “Deep Cycle” batteries (group 27 U-1 Gel).
ConvaQuip Ind., Inc. strongly recommends the use of gel cell batteries. Gel batteries
are sealed and do not require any water to be added. They are also safer and more
convenient to handle since they are sealed and not subject to spilling.
WARNING
IF YOU DECIDE TO USE UNSEALED LEAD-ACID TYPE BATTERIES, EXTREME CARE
MUST BE EXERCISED TO ENSURE THAT THEY DO NOT LEAK OR SPILL. BATTERY
ACID CAN CAUSE SERIOUS DAMAGE TO YOUR SOLO XT550 AND TO SURFACES
IN YOUR HOME OR CAR THAT COMES IN CONTACT WITH ACID. ALWAYS WEAR
PROPER PROTECTIVE CLOTHING WHEN HANDLING UNSEALED LEAD ACID
BATTERIES. REFER TO INSTRUCTION ON THE BATTERIES FOR FURTHER
INFORMATION.
Use care when connecting or disconnecting wires from the battery terminals. Be
sure that the tools you are using do not accidentally drop, or other wise touch both
terminals together.
Severe electric shock, fire, or explosion can result from tools shorting across the
terminals.
Never wear rings, watches or other jewelry while working on or around batteries as
serious injury can occur if an object shorts across the battery terminals.

C24AB14
To charge gel-cell batteries in the Solo XT550
with the charger:
1. Connect the charger plug to the port on the
right side of the accelerator control box
located at the top of the steering tiller. Then
connect the charger plug to a properly
grounded 115 VAC outlet. (See Figure 15)
NOTE: Your Solo XT550 is equipped with a safety mechanism called a “Battery Charger
Interlock.”
This prevents the cart from being driven with the charger plugged in.
2. Charging time may vary from under ½ hour to up to 18 hours for severely discharged
batteries. Normally an overnight charge will suffice.
3. The charger has an automatic shut off. If the charge of the batteries is unknown check it
by unplugging the charger and turning the key on. This will give a reading on the
BATTERY LEVEL METER located on the ACCELERATOR CONTROL PANEL. The
batteries are fully charged when the needle is all the way to the right in the green area of
the meter. Do not check the meter with the charger plugged in as it will give a false
reading. If after charging, the batteries will not take a charge as shown by the BATTERY
LEVEL METER or one or both batteries get warm during charging it could mean that you
need a new battery. Call your dealer.
4. When the batteries are fully charged disconnect the charger from the 115 VAC outlet.
WARNING
The charger for your Solo XT550 must be
connected to a properly grounded 115 VAC
outlet. If it is absolutely necessary to use an
extension cord, use a 3-prong (grounded)
14 gauge or heavier extension cord.
FAILURE TO OBSERVE THIS WARNING MAY
RESULT IN FIRE OR ELECTRICAL SHOCK.
BATTERY CHARGING
SECTION 11
Figure 15

C24AB15
OCCASIONAL USERS:
Always be sure to charge before an outing and always after active use. The ideal recharge
point is about 50% on the battery level meter.
STORING BATTERIES:
Store batteries FULLY CHARGED. Check them once a month and recharge as needed.
And remember, if storing your scooter for longer than a couple of weeks, it is best to charge
the batteries and then disconnect them.
√√
√√
√Use only the charger that came with your Solo XT550.
√√
√√
√Do not use automotive or wet-type chargers on gel/sealed batteries. They will
ruin your batteries quickly.
√√
√√
√Never run your batteries completely flat.
√√
√√
√Do not “top off” with frequent charges.
√√
√√
√Do not store batteries in temperatures below 32°F
INSTRUCTIONS FOR GEL-CELL BATTERIES WITH YOUR CHARGER:
To charge the batteries on your Solo XT550 begin by connecting the power cord to the
charger. Then plug the charger cord into the right side of the accelerator control box. Now
plug the charger into a 115 volt wall outlet. Turn the charger on and look at the indicator
lights on the end opposite the power switch. The red light should be on indicating power is
on. The other light will be orange when the unit is charging and will turn green when
charging is complete. Always place the charger on a hard flat surface with plenty of air
space around it, do not place the charger on the seat of the vehicle.
WHEN SHOULD I CHARGE MY SOLO XT550?
DAILY USER:
Charge daily. This applies to any one who actually uses his or her equipment for
community mobility outside the home
WARNING
Do not expose any battery charger to moisture. Do not connect the charger while
standing in water or on a wet floor. Use the charger on a hard flat surface only. Do
not place it on the seat of the Solo XT550. Do not restrict airflow around the charger.
FAILURE TO FOLLOW THIS WARNING MAY RESULT IN FIRE OR ELECTRICAL
SHOCK. Read and follow instructions in the charger owners guide.
INSTRUCTIONS FOR LEAD-ACID BATTERIES
If you have decided to use lead-acid batteries instead of gel-cell it is of utmost importance
that you read and follow the instructions in the “personal precautions” section of the
charger owners guide, and on the batteries. FAILURE TO FOLLOW THESE PRECAU-
TIONS COULD RESULT IN SERIOUS BODILY INJURY OR DAMAGE TO PROPERTY.
WARNING
RISK OF EXPLOSIVE GASSES FROM LEAD-ACID BATTERIES. WORKING IN THE
VICINITY OF LEAD-ACID BATTERIES IS DANGEROUS. Batteries generate explosive
gasses during normal operation.
√√
√√
√Do not smoke near the charger.
√√
√√
√Do not operate charger near an ignition source or in a non-ventilated area.

C24AB16
DAILY:
1. Charge Batteries as needed. Batteries should generally be charged daily. Unplug the
charger from both the Solo XT550 and the 115 volt outlet each morning. Do not leave
the charger plugged into the Solo XT550 when it is not operating because there is
always a small current drain for the charger interlock relay.
MONTHLY:
1. Check tire pressure and tread wear. Maintain 45 lbs. in front tires and 45 lbs. in the
rear tires.
2. Check and tighten all nuts and bolts.
3. Parking Brake: Be sure the brake will hold you when parked on an incline. If it will not,
it must be replaced. Consult your ConvaQuip dealer.
4. Inspect all electrical connections for damage and corrosion.
ANNUALLY:
It is recommended that your ConvaQuip dealer perform an annual inspection of your
Solo XT550. Many times he or she may be able to prevent problems before they
happen, saving time and inconvenience.
GENERAL INFORMATION:
Cleaning: The body covers on your Solo XT550 are made from a high grade ABS
plastic. Use only a mild soap and water for cleaning. Do not use any petroleum based
solvents since they can damage the finish. Clean the vinyl seat cushion with a mild
