Stewart Golf FAQs and Technical

Before going further, do read the instructions that come with every trundler, battery and charger supplied by Stewart Golf.
All manuals you can find here.
X Series
1) Are X9 batteries compatible with lead-acid chargers?
X9 batteries must only be charged using the charging equipment supplied with the battery. It is not possible to charge the battery using any other charging equipment.
 
2) Are X9 batteries dangerous?
No is the simple answer! Unfortunately, certain other types of Lithium battery can be dangerous if not treated in the correct manner. The X9 battery is made from LiFePO4 (Lithium ion Phosphate) which is widely recognised as the safest type of lithium battery. This makes it the material of choice for electric vehicle manufacturers.
3) How long will an X9 battery last?
The lifetime of a battery is determined by a number of factors including regularity of play, weight of golf bag, course type, trolley age and trolley type. With this in mind it is not possible to predict how long a battery will last.
4) How should an X9 battery be stored if not used for considerable periods of time?
For storage in excess of four weeks, it is recommended to fully charge the battery before reducing the level of charge to around 60% (ideally by using it for 40% of its capacity). It should then be fully charged prior to its next use.
5) Is it possible to use an X9 battery and still use a lead-acid battery?
Yes. The X9 battery is designed to work just like a lead acid battery with no modification required.
6) Should a X9 battery be recharged if not been used for a full round?
X9 batteries do not suffer from a “memory effect” seen in certain other high technology batteries. This means that it will not cause any damage to the battery. The only effect will be a quicker charge!
7) What is the safest way to dispose of an X9 battery?
At Stewart Golf we are dedicated to protecting the environment and strongly recommend disposing of our batteries in a safe and environmentally friendly way. X9 batteries can be taken to a registered recycling point or alternatively returned to Golf Warehouse to allow us to dispose them.
8) What maintenance is recommended for X9 batteries?
In addition to regular charging, it is recommended to regularly check the battery connections and keep the battery clean with a damp cloth.
9) What battery can I use as a replacement on my X9?
1. Lithium Phosphate (LiFePO4)

This is the battery that is supplied as standard with the X9 models and is the option that we recommend. It has several significant benefits over the lead-acid battery, such as:

Weight reduction (3kg instead of 12kg)
Smaller size
Longer overall life
More reliable charging
Constant power delivery (so the trolley won't slow towards the end of a round)

This is supplied as a set with battery and charger - your old lead-acid charger will not charge the new lithium battery.

Misc

1) How do I brake when going down hill?
On most 'manual' or single motor trolleys, it is highly likely that the rear wheels will incorporate single direction Sprag Clutches. These are designed to allow the trolley to be driven as well as freewheeled forwards. This is to help the golfer to steer the trolley easily, however the other effect is that the trolley could 'run away' when going downhill (unless prevented by the golfer holding on to the handle)

Stewart Golf remote controlled golf trollies have direct drive in both directions through a 25:1 worm wheel gear box. This is required to allow the steering to work effectively in both directions, as well as allowing the machines to drive backwards and forwards. This also has the effect of dramtically slowing the trolley when going downhill. It also has the addition of an emergency brake that will bring the unit to a stop if required (this is not a 'true' brake, so the trolley may still 'creep' when on a steep hill). Also by making small turns down a steep hill the speed can be controlled even on the steepest of hills (because during a turn one wheel uses the braking mechanism)


2) What type of motor brushes do I have?
To ascertain the type of motor brush you need to check if the motors on your trolley have the 'nodes' on the top and bottom of the cylinder that holds the brushes (like in the image at http://www.stewartgolf.co.uk/product/X-MOTOR/X-Series+Motor) if so, then you have the changeable brushes or if the brushes are held in the end caps of the motors then you need to replace the end cap assemblies.

If you have any doubt, please send an image to info@stewartgolf,com.

3) How do I put my trolley into freewheel mode?
If you want to put your alloy or V3 wheels in to the free wheel mode, please follow these instructions. Firstly, with one hand tip the trolley slightly to lift the wheels of one side off the ground. Using the other hand, hold the hub of the wheel with your thumb on the black button. Press the button fully and withdraw the wheel by 4cm (or so) and turn it by around 45 degrees and then push the wheel back towards the trolley. Release the button and waggle the wheel to ensure the button comes back out and the wheel spins freely. Repeat for the other side.

To re-engage drive, lift the wheels of one side off the ground with one hand and use the other hand to hold the hub of the wheel with your thumb on the black button. Fully depress the button and apply light inward pressure while turning the wheel slowly until the wheel goes a further cm or so. Release the button and waggle the wheel to ensure the button comes out and the wheel is secure and wheel is stiff to turn.

4) How do I set the trim (Motor Balancing) on my trolley?
Over time the two motors in your trolley can wear unevenly. This may cause the trolley to 'lean' to one side when it should be going in a straight line.

You can fine-tune the 'trim' from the handset by using the procedure below:

1. Place the trolley (with bag) on a flat surface.
2. Press and hold both the 'brake' and 'off' buttons for 5 seconds until the trolley starts off. On older trolleys press the 'off' button (next to the 1,2,3,4 buttons) for 10 seconds, or until the trolley starts off.
3. Use the left and right buttons to fine tune the steering until you have the trolley going straight.
4. Press the brake (the red button) to store this new setting.
5. Repeat steps 2-4 until you are happy that it's straight.

5) I have broken my belt clip, what do I do?
If the clip on the back of the remote handset of the X or F Series has been over stretched this can cause fatigue and eventually break. Don't worry though as this can be easily repaired.

You have two options:
1. Replacement handset back & clip.
We have put these parts together so that you just have to remove the two screws at the top & bottom of the handset, replace the whole back moulding and then replace. You should see that the handset has been sealed with silicone sealant. Ideally you should do this as well to guard against water ingress.

2. Silicone Handset Skin.
The handset skin can be fitted to any remote handset. It comes supplied with a new handset back and a new extended and extra flexible belt clip (it has to be extended to compensate for the thickness of the skin).

Note: Older handsets with silver button pads can still use the skin, but the buttons may not align perfectly. Both are available to buy online, please look under the 'Spares' tab or search for 'handset' using the search bar.
