•
Switch lamp to LOW BEAM mode and visually observe placement of low
beam on rear alignment screen of HBA 5. Pattern should be in a relative
position of alignment and appear as pictorial.
Q: The lights keep blinking on the control panel, what does this mean?
A: Continue blinking of the lights on the control panel indicates either the internal battery requires charging, or that the system is not in
front of a light pattern. It will require twelve (12) hours to full charge battery in system.
Q: How do I measure floor slope?
(Page 6~7: Section 3.2)
A: Move the aimer bay to be measured and in front of the vehicle. Move the aimer to approximately one foot outside side of the vehicle
and lower optical head to lowest point. Place laser on optical head and turn laser on. Using a tape measure or yard stick, go to the
front wheel area of the vehicle and measure up from floor to where the laser strikes the tape, note measurement. Go to the rear wheel
area of vehicle and again measure from the floor up to the laser, noting measurement. If measurements differ, rotate the rear floor
slope eccentric on the base until both height measurements are equal. Note the setting of the eccentric wheel tape and record setting
on the floor slope registry.
NOTE: Measurements are required for each bay that the HBA 5 is to be used.
Q: Do I need to always use a track? Does the track need to be attached to the floor?
(Page 6: Section 2.5.1)
A: The track is provided to smooth the floor surface and to ensure the system will roll evenly across in front of the vehicle once the
system has been squared to the vehicle. When the system is operated without the track, the system must be squared on each side of
vehicle prior to aligning that sides lamp(s).
NO, the track need not be attached to the floor for proper and accurate alignment.
Q: How do I square the system to the vehicle?
A: While standing behind the system, with system placed in front and centered on vehicle, rotate the mirror down until you can see the
reflection of the front end of the vehicle in mirror. Locate two symmetrical points on the hood or under the hood and pivot the
optical head until the horizontal line on the mirror intersects the two select symmetrical points. System is squared.
Q: What do the boxes mean on the aiming screen?
A: The inside box is equal to four (4) inches Up/Down and Left/Right at twenty-five (25) feet. The larger outside box is equal to eight
(8) inches Up/Down and Left/Right at 25 feet. Check your state regulations for inspection tolerances.
Q: The laser does not light up. How do I change the batteries? (Page 9: Section 4.1)
A: The laser requires three (3) LR44 batteries to operate. To change batteries, remove the On/Off thumb screw and peel back the label
until the set screw is exposed. Using a 5/64 th Allen wrench loosen the set screw until laser slides out of housing. Unscrew the rear of
laser and remove the old batteries and replace with new. Test laser prior to inserting into holder.
Insert laser into holder, carefull to align On/Off button on laser with thumbsrew hole. Lightly tighten set scew to secure laser in
holder and replace label. Inset On/Off thumb screw and test laser operation.
Calibration of the laser is required any time the laser is removed from the holder. Calibration instructions can be found on
page 9, section 4.1.
Q: There is a level vial attached to the bottom of the aiming screen. What is its purpose? (Page 3: Section 1.3)
A: This vial is used to ensure of vertical straightness of the aiming screen. During assembly of the unit there is an eccentric wheel on the
front of the base that must be correctly positioned to ensure that the mast, optical head and aiming screen are vertical as an assembly.
There is a small scribe mark on the front eccentric wheel that is to be placed directly in line with the indicator arrow on the base.
Should the vial on the aiming screeen be utilized for calibration, the unit must be placed on a true level surface and the front eccentric
rotated until the bubble is centered.
