Starting your cart
When switched on, your cart will start in the last Mode you used. Your new cart will
start in Mode 0.
This is the Competition Mode and allows adjustment of speed without any distance
measurement.
Speed Adjustment
To start your cart in Mode 0, briefly press the Command button. Your cart will begin
to move forward. To adjust the speed , turn the Command Button clockwise to

the speed setting or the distance setting.
Cruise Control
When you wish to stop your cart, briefly press the Command Button. Your cart will
memorize the last you speed setting.
When you want to start again, briefly press the Command Button and your cart will
resume at the previous speed.
Constant Speed Feature
Your cart measures each revolution of the wheel to determine speed and distance.
This sensor will ‘feed-back ’ to the microprocessor and automatically increase or
decrease the motor power to suit the terrain. Your cart will automatically adjust

when going uphill and thus maintain a constant speed. Please be aware that on
steep downhill slopes your cart will Not slow down due to freewheel function and
gravity! Please keep control of your cart when going downhill. The cart may slow
down on steep slopes due to the gearing.
Mode 1- Speed Setting
Press the Mode Button until Mode 1 is displayed.
Turn the Command button clockwise to set your speed. There are 10 settings, S0 to
S9 . Most users find setting S6 or S7 the most comfortable.
After setting the speed, briefly press the Command Button and your cart will move
forward and run at a constant speed. To adjust the speed, turn the Command
button to increase or decrease the speed.
When your cart is moving, the display will show the speed you are traveling in mph
or kph. This may vary slightly as you go up or down slope but will generally be a
constant speed.
To stop your cart, briefly press the Command Button. The cart will stop, the speed
display will revert to ‘0.00’ and the Motion Indicator arrow will turn off.
To resume, briefly press the Command button. Your cart will resume at the last
speed setting(Cruise Control).
Mode 2- Distance Measurement
When you access Mode 2, the distance Indicator will be set to ‘000’. As you move

your cart by briefly pressing the Command button, the counter will stop and then
resume counting when you move forward again.
If you move out of Mode 2, or switch off your cart, the Indicator will revert to ’000’.
If you want to calculate the distance to the green, set Mode 2 at, say, the 150yd
marker and measure the distance to your ball. Deduct this from 150 and it will give
you the yardage.
If you wish to reset the counter to zero, move out of Mode 2 or switch off your cart.
Mode 3-Distance Control
Access Mode 3 by pressing the right Mode Button.
With your cart stationary, rotate the Command button clockwise until the distance
you want to travel is displayed on the screen- from 1 to 999 yards/meters ! Please
note –if you try and turn the Command button too quickly, the display will count up
more slowly! A moderate turn is the optimum.
Point your cart in the right direction and briefly press the Command button. Your
cart will travel the set distance and then stop and wait for you.
Most users find this particularly good for sending their cart off to next tee , usually
around 50 yards. If you hit a super drive and want to walk ‘hands-free’ behind your
cart, set the distance to say, 250 yards ! The cart will stop after this distance.
When you want to reset a distance, the cart will start at the last setting, even though
the display shows ‘000’. If you had last set the distance to ‘55’ when you turn the
Command button it will count up or down from ‘55’.
Setting your cart to travel without your control can be hazardous. Always ensure
that the stabilizer wheel is fitted. If your cart goes up a steep incline and the
stabilizer wheel is not fitted, the cart may tip backwards damaging your cart, your
clubs and you vanity!

CAUTION

Electric Golf Cart User Manual

A bump in the grand may know your cart off course and send your cart into a hazard
or a cart- please take care.
Finally, do not send your cart to stop on a down slope. Your cart has no brakes and
has a ‘freewheel’ so it will not stop on a down slope. Gravity will take over and your
cart may end up at the bottom of the hill !
Please use your cart sensibly and avoid damage to your cart, yourself and other
golfers.
Mode 4- Universal Counter
In Mode 4 you have access to a ‘Counter’. This is useful if you want to count strokes
taken, Stable ford points, number of putts taken or just about anything else.
To increase the counter, simply press the left button. Each press will add 1 to the
count. The total will be memorized.
To reset the Counter to ‘000’ , switch your cart off and back on again.
Battery Indicator
The Battery Indicator will show the amount of charge in your battery. When 4 bars
show, the battery is full. The number of bars will reduce as the battery charge drops.
When only one bar is shown, you will have only enough charge for 4 more holes.
When the charge drops below a critical level, your cart will automatically switch off
to prevent any damage to the battery or the electronics.
Automatic Switch-off
If you do not use your cart for a period of 10 minutes, the cart will switch off
automatically and any memory settings (Distance, Distance Control, Counter) will
be lost).

6. Charging the battery.
Always start every round with a fully charged battery.
Charge your battery as soon as possible after every round (certainly within 24 hours)
even if you have played only a few holes. This will maximize the life of your battery.
To charge your battery, ensure your charger is not connected to the mains and
connect it to the battery. Connect the charger to the mains. If the green light on your
charger flashes, switch off immediately and check the polarity of the charger leads.
The charger light will turn red indicating that charging is taking place. When your
battery is charged, the light will turn from red to green. With a new or fully charged
battery, the red light may show only for a short time before turning green.
Ideally, you should charge your battery for a minimum of 8 hours, even if the red light
turns green before this. This will ensure that the maximum charge is put into the
battery and will increase battery life.
The charger supplied with your cart is a modern 3 stage charger. We recommend
that you leave the battery connected to the charger with the mains until the next time
you play golf. The electronic circuits in the charger will protect your battery from
over-charging and will ensure your battery is kept topped-up.
Switch the charger off at the mains before disconnecting the battery. If you do not
intend to use your cart for several months, fully charge the battery and then
disconnect from the charger. Recharge your battery every 30 to 45 days. Leaving the
battery on charge for an extended period may cause the battery to dry out and
shorten the life of both the battery and charger.
You must give your battery an initial ‘commissioning’ charge before using it for the first
time. Charge your battery for a minimum of 16 hours, even if the green light appears
soon after commencing charging.

DO NOT leave the charger connected to the mains if the battery is not attached. This
will shorten the life of the charger.
DO NOT leave the charger connected to the battery if it is not connected to the mains.
This will discharge your battery.
DO NOT charge your battery on a concrete floor - always charge on a shelf/bench
or place the battery on a plank of wood.
7 Use & Maintenance
Battery
1) Regularly check to see if the battery is damaged
2) Keep the battery surface clean, and check underneath the battery cover to
make sure that no dirt or water has attached to it.
3) Check the battery connections – underneath the small plastic covers – for
any signs of corrosion or bad connection.
4) Check that the wires from the battery cover are firmly fixed to the terminal
posts.
5) After use always place the battery on charge – in warm dry conditions.
6) If the cart will be used again soon then you can leave the battery on charge
until that time. Always allow sufficient charging time to completely charge the
battery – overnight or 6 to 8-hours should be sufficient.
7) If the battery is to be stored – for instance over winter – and not used it can
be disconnected. If disconnected for storage always recharge the battery
completely at intervals – at least once every 30-45 days. Allowing the charge
of the battery to drop to a completely exhausted state can shorten the life of
the battery.
8) Do NOT charge the battery with a different charger that that supplied with
the cart.
9) If stored place the battery on a wooden shelf – not on a concrete floor. Keep
away from fire – flames – heaters – and do not allow it to be in a temperature
of over 45 deg C (113 deg F)
