Low Batt
Change Soon
on display when batteries needs
replacement (at this point you still have
approximately 2 hours of run time).
Power consumption is so low that it
should not be necessary to replace
more than once per season. There are 2
types of batteries used and 2 different
battery access locations, depending on
production date:
• 9 volt access is on the front or side of
the control box. There are 2 battery
‘drawers’. Push down with your
fingernail and pull out. Replace both w.
quality Alkaline 9 volt batteries.
BE SURE THE POLARITY IS CORRECT.
• AA battery access is on the outside
bottom of the carrying case. Replace
batteries with 6 quality AA Alkaline.
BE SURE THE POLARITY IS CORRECT.
There is no recharger or rechargable
batteries since the battery life is so long.
Zero:
Push BEFORE putting car on
scales.
DON'T push Zero AFTER car is
on scales.
Weights &
Partial % Displays
These 2 buttons let you show either 4
wheel weights and cross - OR - all
partial weights and %. You can go back
and forth as needed. Do NOT reZero.
There are 2 different displays for both
Wheel Weights
and
Partial %
. See
examples at the right. If you want the
other one push the
Wheel Weights
or
Partial %
button and hold for 6
seconds. That display will change and
will stay until you change it again.
NOTE: “Bite” is LR minus RR.

scales. Allow to warm up for a
minute or so.

Instructions for Model #s.
General Tips:
• Keep the system clean and dry.
Do not drop either the pads or the
control box.
• Route the cables so that no one
trips and they do not get run over
by floor jacks.
• Store in a clean dry place.
Remove batteries if scale will be
stored unused for more than 3
months
• Capacity per scale pad is:
1500 lbs. for #72594 & 95 (15” pad)
2500 lbs. for #72595 (w. #72999
upgraded 15” x 4” tall pads)
1100 lbs. for #72581 (12” pad)
400 lbs. for #72625 & 26 (kart pad)
WEIGHT OVER THIS COULD
DAMAGE LOAD CELLS
and cannot be warrantied.
• Keep away from static electricity.
1) Set up pads along side car. Scale pads are marked RF, LR, etc. They are closely matched and can be interchanged if desired.
2) Connect cables from control box - note RF, LR, LF, etc. Cables MUST be connected to this corner of the car.
3) Turn on control box, allow to warm up for a minute or so. Push Zero. This defines "0" weight. DON'T PUSH ‘ZERO’ AFTER CAR IS ON SCALES.
4) Lift car and place pads under wheels. For more consistant cross weights "shake" car up & down at each corner to settle out any shock or suspension friction.
5) System shuts down after 1 hour to extend battery life. Simply turn back on. DO NOT REZERO unless car is off scales.
