Initial Set-Up
1. Install the two large drive wheels on the correct side of the
trolley. The arrow design on the tire should face forward, and
each wheel hub has a side indicator on it. Depress the release
pin on the inside wheel hub, and fully seat wheel onto axle drive
collars. The metal screws should fully insert into the holes on
the drive collar.
2. Install front wheel and fork assembly. Review the following
drawing and install the front wheel.
OPERATING YOUR
GRi-975Li
1. Lift lower handle.
2. Load golf bag onto the
trolley, bottom first, then the
top. Balance weight of golf
bag equally “side to side”.
3. Secure golf bag with
bungees. Slide one ball through the space in the opposite
bungee. Securing your golf bag on the cart locks the cart in
the “open” position. It is important that both top and bottom
bungees are tight. If one bungee is loose, you can tighten this
connection by putting a knot in the bungee to shorten the
length.
4. Extend the upper handle into the desired position and secure it
by turning the black locking knob.
5. Ensure the speed dial knob is rotated counterclockwise to the
“Zero” position.
6. Insert your battery cable into the battery port and secure the
battery inside your golf bag with the supplied extension cord or
inside the optional battery basket. The status LED on the cart
should be an alternating long and short flash.
7. Roll the speed dial forward to deliver power to the motors. Set
this speed to your desired walking pace.
8. To stop the cart, press and release the button on the cart. The
cart will come to a stop and apply the electronic parking brake.
As a precaution always turn the trolley across the hill if parking
on a slope. To disengage the parking brake, turn the speed dial
to zero, or resume your walking pace by pressing the button on
the cart once more.

DISTANCE CONTROL
FUNCTION (DCF):
When the trolley is stopped (with the parking brake engaged), press
and hold the LED until it flashes rapidly (Approximately 2 seconds).
When you release the button, the GRI-975Li will move forward for 8
seconds at the currently set speed.
FREE-WHEEL MODE
If you have a sudden loss of power, you must put the Trolley into
“Free Wheel Mode” to safely move the trolley. For “freewheel”
mode depress the buttons on each wheel hub and pull wheels
out approximately 1/4 of an inch, away from the drive collar on the
motor. Make sure the wheels are engaged into the freewheel groove
on the axel.
Free Wheel Groove
PRECAUTIONS
1. For best performance, cart bags are recommended. If you use a
carry bag or stand bag you may need to add weight and secure
the stand legs. (See # 4 below)
2. Consider the all-around weight distribution of your golf bag.
Ensure the bag is balanced evenly side-to-side. Uneven weight
distribution may lead to “tracking errors” i.e. too much weight
on the right side will cause the trolley to veer to the left.
3. The front wheel should stay grounded during play at all times.
On steep inclines, you may find the front wheel coming up,
o the ground. You must maneuver the front wheel down by
holding the handle upwards. The cart will still power the wheels
up the hill. You are simply helping balance the caddie up the hill.
4. If you are having issues keeping the front wheel down on the
ground on slight inclines, increase the weight over the front
wheel. Consider adding extra golf balls, or bottles of water to
your bag closest to the front wheel if possible. Equally distribute
the weight in your golf bag. Use the center pouch or equal
weight added to each side.
5. To minimize the drain on the battery avoid driving through deep
rough.
6. Avoid using the GRI-975 to pull you up hills.
7. Do not pull Trolley backwards while riding in a cart. If you need
to pull trolley backwards for an extended distance, disconnect
the battery and swap the wheels from left to right and ensure
the wheels are in free-wheel mode.
CAUTION: Wheels can disengage in sharp turns or
from excessive speed if you do not swap the wheels
from side to side.

If the cart is tracking to the left (from behind the cart):
1. Loosen the 17mm locking cap nut on the Fork side.
2. Loosen the front #2 Allen set screw 1/4 of a turn (90 degrees).
3. Pull the axle tight against the front set screw.
4. Tighten the 17mm cap nut.
5. Test alignment. Readjust if necessary.
6. When satisfactory alignment is achieved, tighten the rear
set screw down to the axle. Ensure both set screws are snug
against the axle.
When first using your trolley, practice in a large open area. Take the
time to practice controlling the trolley with the start-stop switch on
the handle and using the distance control function.
ALIGNMENT SYSTEM
If you have issues with your trolley not going straight you may have
to adjust the tracking. Keep in mind that the cart will drift slightly
depending on if you have steep side slopes, rough terrain, etc. On
a perfectly flat fairway, a normal tolerance of drift is 1 foot over a
50-foot run.
1. VERIFY both wheels are fully engaged in the drive collar.
2. VERIFY the front fork is tightly secured. Sometimes the 6mm
hex bolt will come loose, causing the fork to make erratic
movements. If your bolt comes loose more than once, apply
some thread locker to the bolt.
If the cart is tracking to the right (from behind the cart):
1. Loosen the 17mm locking cap nut on the Fork side.
2. Loosen the rear #2 Allen set screw 1/4 of a turn (90 degrees).
3. Push the axle tight against the rear set screw.
4. Tighten 17mm cap nut.
5. Test alignment. Readjust if necessary.
6. When satisfactory alignment is achieved, tighten the front
set screw down to the axle. Ensure both set screws are snug
against the axle.

My caddy will not move, what can I do?
If your caddy experiences some kind of failure on the course and
you cannot get it running, you can put the caddy in “free wheel”
mode.
1. Press the lock button on the inside wheel hub and pull each
wheel out of the drive collar and lock the wheels into the free
wheel grove on the axle.
2. In free wheel mode, you should not pull the caddy backwards
for more than 5 feet.
My caddy stops unexpectedly during a round.
1. Check indicator LED’s on end of caddy handle.
• No light – Make sure your battery is connected to the
caddy receptacle. If the connection is good, you may
need to replace the battery cable or extension cable.
• Rapid flashing BLUE LED is an overload high current
warning. Stop and Allow caddy to cool down. This can
be caused by too much weight on your caddy or trying to
climb too steep of hill.
• Flashing BLUE LED is standby mode, you have
temporarily lost and regained power. Check battery
cable/connections. If this happens many times in a row,
your battery could be completely drained, or you may
need a new battery cable.
• Very Slow Flashing BLUE LED is low voltage warning.
Stop or use Free Wheel Mode, do not use the battery,
and recharge battery.
TROUBLESHOOTING
My caddy will not show any indicator LED on the handle.
1. Ensure both the battery and wall charger are fully plugged in.
2. A fully depleted battery may take upwards of 6 hours to
charge.
My caddy will not make 18 holes.
1. Verify that your charger is charing fully. Your battery should
read 29.3 volts.
2. Ensure both the battery and wall charger are fully plugged in,
when charging.
My caddy has erratic steering (i.e. Spins to the right/left, goes
forward/backwards when pressing right/left).
1. Ensure both wheels are fully engaged into the drive collars,
located on the axles.
My caddy does not track in a straight line.
See section: ALIGNMENT SYSTEM on page 14.

IMPORTANT CUSTOMER
CARE INFORMATION
1. Mount wheels with arrow tread design pointing in direction of
wheel spin. If pulled backwards in free wheel mode, reverse the
wheels so that the tread arrows point in direction of rotation.
2. Mount the golf bag prior to opening the top handle in order to
avoid tipping the cart over and damaging the start/stop button
3. Likewise, lowering the adjustable handle before removing your
golf bag will help prevent knocking the cart over
4. Consider the all-around weight distribution of your golf bag.
Ensure the bag is balanced evenly side-to-side. Uneven weight
distribution may lead to tracking errors. I.E., if there is too much
weight on the right side, the caddy will drift to the left.
5. Periodically spray the front wheel bearings with a silicone-based
lubricant.
6. Clean your cart with a damp cloth and or compressed air. DO
NOT spray the cart with water.
