Turn on: Push ON/OFF. AccuLevel™ is ready to use. ABS
ABS ABS ABS ABS will appear on the display if the unit is in
Absolute Angle Measurement Mode. If it does not display ABS
ABS ABS ABS ABS push ZERO. Otherwise DO NOT push ZERO.
Zero: The ZERO button is ONLY used to compare one angle to another and in measuring caster (see CASTER
section). Place AccuLevel™ on an angled surface and push ZERO. The display will go to 00.0
00.0 00.0 00.0 00.0 and ABS ABS ABS ABS ABS will
disappear. Move to a different surface to compare angles .FOR NORMAL USE ABS

To hold reading: Push “HOLD”. The display will show HOLD and flash . When HOLD stops flashing (approx. 6
sec.) the reading is held on the display. AccuLevel™ must be head very steady during this 6 seconds. Push

Instructions For No. 78110 Kart Digital Caster/Camber Gauge
1) Find a level place to set up your front end. This unit reads camber very accurately. Unlevel
ground will affect that accuracy.
2) Attach the gauge to the spindle by screwing onto the extra threads outside the nut. If there
are none remove the nut and screw the adaptor on until the the hub is tight. When done reinstall
the spindle nut and pre-load bearings as required.
BE SURE WHEELS ARE POINTED STRAIGHT AHEAD WHEN SETTING CAMBER.
3) Rotate the gauge until the small vial on the top of the gauge shows level.
4) CAMBER: Turn on the AccuLevel™ Digital Readout by pushing “ON/OFF”. Camber is
read directly on the display to .1 O (1/10 O ). See separate
AccuLevel™
below instructions if
needed. On the left side of the display a pointing up indicates negative camber (top of tire
in). A pointing down indicates positive camber (top of tire out). Race cars usually use nega-
tive camber on RF and positive camber on LF.
5) CASTER: To set caster more precisely using the AccuLevel™ digital readout first turn the
wheels 15 O (this is different than when using vial type gauges) to the right when setting the RF
or 15 O left when setting LF. Rotate the gauge until it is level.
6) Turn on the AccuLevel™ and push ZERO to zero degrees at that point (shows
00.0 00.0 00.0 00.0 00.0
O ).
7) Turn wheels back to center and continue to 15 O in the other direction (a total of 30 O ). Again
this is different than when using vial type gauges. The 15 O must be done accuretely. An error
of even 1 or 2 O turning will give a noticeable caster error.
8) Rotate gauge to level. Read the digital display and DOUBLE THE NUMBER FOR (TOTAL)
CASTER, accurate to .1 O . For example display reads 4.8 O x 2 = 9.6 O caster.
