After unpacking the trolley and while reading this manual, place
the battery on charge while you assemble the unit. Plug battery
into charger and charger into power source. The battery may be
delivered with a charge but you should verify a full charge before
using the trolley for the first time.

•Install front wheel. Review the following drawing and
install the front wheel.
•Lift lower handle.
•Load golf bag onto trolley. Balance weight of golf bag
equally “side to side”. Secure golf bag with bungees.
•Securing your golf bag on the cart locks the cart in the
“open” position. It is important that both top and bottom
bag straps are tight and your bag is firmly secured in the
bag rests.

•Extend upper handle into desired position and secure by
turning black locking knob.(mount bag first)
•Attach extension cable to battery. Place battery in a
convenient pocket in golf bag where the cable will reach
the battery port without stress.
TURNING ON YOUR GRX-965LI / GRI-975LI
Turn speed knob back counter clockwise to the stopped
position. Plug battery cable into the electrical port on trolley
handle. The LED on handle will be a solid blue. (When initially
plugging in your battery if you see a flashing LED your speed
knob is not at zero.) Trolley is ready to go. Turn speed knob
forward to desired speed. To stop trolley turn speed knob
back to zero.
Alternatively, the trolley may be controlled by using the push
button at the end of the handle. (Where the blue LED is
located). Simply push the button while the trolley is moving
and the trolley will stop. The LED will triple flash. Push the
button again to resume at the same pace.
Distance Control Function: when the trolley is stopped, press
and hold the LED until it flashes rapidly. Release the button,
the cart will move forward for 10 seconds at the currently set
speed. (Distance control function will not work when cart is
stopped via the speed dial.)

To engage the “parking brake” stop caddy with on/off button.
As a precaution always turn trolley across hill if parking on a
hill. To disengage parking brake, turn speed dial to zero (carts
with AMB must press the on/off button with speed @ zero)
FREE WHEEL MODE
In the event that you have a loss of power or have a need to
pull the GRI-975Li backwards, you must put the Trolley into
“Free Wheel Mode”. For “free wheel” mode depress button on
wheel hub and pull wheels out approximately 1/4 of an inch,
making sure the wheels engage into the next axel position. The
metal prongs on the inside wheel hub will show and will not be
engaged with the drive collar. You can now safely pull cart
backwards slowly.
PRECAUTIONS
1) For best performance heavy cart bags are recommended. If
you use a carry bag or stand bag you may need to add
weight. (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 trolley to veer to
the left.
3) The front wheel should stay grounded during play. If on
steep inclines your trolley’s front wheel comes off of the
ground, maneuver front wheel down with handle.
4) If you are having issues keeping the front wheel down on
the ground, increase the weight over the front wheel.
Consider adding a water bottle full of sand inside a low
pouch in your golf bag. Equally distribute the weight, use
the center pouch or equal weight added to each side pocket.
5) During play, minimize the drain on the battery by avoiding
taking the trolley into the rough.
6) Avoid using the trolley 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 pull the main drive wheels out
to the free wheel mode groove on the axel.
CAUTION: Wheels can disengage in sharp turns or from
excessive speed.
BATTERY MAINTENANCE
Your GRI-975Li Trolley comes with a 24 volt, 7.5 Ah Lithium
Ion battery.
Whenever possible we ship your battery fully charged. Before
trying to operate your cart, please verify that the Li battery is
fully charged. Plug your battery into the charger; and then plug
your charger into the power source. Your trolley is ready for
play when your charger LED flips from orange to green. It is
likely that your battery will need very little charge time before

Page 9 of 13
being ready for play the first time. Normal charge time is 3-4
hours after a full round of golf.
✓Always ensure battery is connected to charger when
connecting AND disconnecting charger from power
source.
✓Your battery charger should not be left plugged into the
power source when not in use.
✓The charger has a green LED light when inserted into a
power source if it does not have a battery connected to it.
✓Do pay attention to the charger lights and verify that the
charger flips to orange when a depleted battery is
plugged in. (Depleted meaning you played golf.)
✓To maximize battery life, charge your trolley battery
immediately following your round of golf. Charge your
battery after any use, even if you only played 9 holes.
✓The LED on the charger will turn green when battery is
fully charged. A full charge usually takes between 3-4
hours. Charge the battery in the evening, unplug in the
morning. Do not leave your battery on the charger for
extended periods; do not leave the charger plugged into
power source.
✓Provided your next golf game is within 3 weeks your
battery is ready to go and there is no need to top off.
✓During periods of inactivity (i.e. winter storage) re-charge
your battery overnight every 12 weeks. Battery life is 500
plus charging cycles, depending on course conditions.
✓Store your battery at normal room temperature. Avoid
freezing temperatures.
✓Do not store or charge battery on concrete surface.

✓At the plug end of the battery cable check to see that the
cable has not become loose or "unscrewed" from the
plug. Tighten compression ring if needed.
✓Take precautions and be careful to not drop the battery.
The battery casing could crack and the subsequent
battery life will be severely compromised.
✓Do not strain or pull on battery cable. Always push silver
slide latch on round plug when inserting and removing
from cart or charger.
ALIGNMENT SYSTEM
If you have issues with your trolley not going straight you may
have to adjust the tracking. Verify that the trolley has a
tracking issue without a bag before making any adjustments. If
you only have a tracking issue with the trolley when your golf
bag is on the trolley adjust the weight in the golf bag.
In order to adjust the alignment you will need to loosen a
locking CAP nut and two #2 Allen sets.

Page 11 of 13
When standing in the front of the trolley looking at the front
wheel, loosen the 17 mm nut on the right side of the front
wheel.
Depending on how the trolley is tracking, will determine which
way to turn the Allen set screws.
17 mm CAP NUT
FRONT of Allen Set Screws
Turn with Allen Wrench

Page 12 of 13
The Allen Set Screws should be gently turned on both the front
and back sides an equal amount.
If the Trolley is tracking to the right, (when standing behind
the trolley) turn the rear side of the Allen Set screw counter
clockwise. Turn the front of the Allen Set screw clockwise.
Turn both sides equally.
If the Trolley is tracking to the left (when standing behind the
trolley) turn the front of the Allen Set screw counter clockwise
and turn the rear side of the Allen Set screw clockwise.
Retighten 17 mm cap nut. Test and repeat if necessary.
QUICK TIP
FOR WARRANTY, SPARE PARTS AND ACCESSORIES:
When first using your trolley, practice in a large open area.
Take the time to practice controlling trolley with the start
stop switch on handle and using the distance control function.
