at time of initial setup.
Make sure to loosen the attachment screws for the
axle block before attempting to adjust the wheel. Damage will occur if
this step is not accomplished first.
2.4.3 WHEELS TO WHEELBASE MOUNTING
There are three wheels on the wheelbase. Two wheels have an axle block that allows them to fit inside the
wheelbase, and be adjusted. Each axle block has two bolts, one for mounting to the wheelbase, and a second for
clamping the wheel axle into the block. The eccentric wheel is installed on the right leg of the wheelbase. The
straight shaft wheel is applied to the left leg of the wheelbase. The slope adjustment wheel is applied to the rear
leg Of the Wheelbase.
2.5 FLOOR RAIL
The floor rails are provided for guiding the horizontal movement of the wheelbase along the floor before the
vehicle. The floor rails assure that the alignment of the wheelbase to the vehicle does not change when moving
from lamp to lamp. The rails are attached together by using 1/4” dowel pins. Permanent attachment can be
accomplished by simply placing a couple of drops of locktite to each dowel pin before mating rails.
2.5.1 FLOOR RAIL OPERATIONS
It is recommended that the floor rail be positioned no further than 20 /- 3 inches from the face of the
headlamp lens, and perpendicular to the centerline of the vehicle. The wheelbase’s two front wheels are placed
in the valley of the rail, and the rear wheel can be adjusted to conform to the floor slope of the work bay.
The floor rail is shipped in two 4-foot lengths. Included with the rails are two 1/4” dowel pins.
To assemble, slide the rail with dowel pins in the end of the rail with the arrow, and over the pins until the
edges are flush. The two pieces should hold each other firmly with no loose movement.
NOTE
: If attachment of rail guide to floor is desired it will be necessary to drill holes on each end of
the rail into the working surface to accept anchoring devices.
2.6 VEHICLE POSITIONING MIRROR
The vehicle-positioning mirror is used by the operator as a guide in
positioning
he HBA 5 perpendicular to the vehicle headlamp. The mirror contains a
printed line that runs horizontally in the middle of the glass, which serves as
an eyesight guide in aligning the vehicle.
Tension of rotation of mirror should be snug, but loose enough to allow the
mirror to turn.
2.7 ALIGNMENT HEAD & MAST
The alignment head is attached to the mast by the glide plate. The head fastens to the glide plate by four 1/4-20 x
1/2 Button Head Cap Screws.

OPERATING
PROCEDURE
3.1 ALIGNMENT PREPARATION
Certain preparations must be made prior to beginning the alignment process.
1.
The alignment area floor should be clean and clear of any unusual objects that could distort the position of the vehicle or the HBA 5 itself.
2.
The vehicle should be free of any ice or mud, in and around, the fenders and headlamps. The vehicle should not have any suspension problems, bad
shocks, springs, or struts causing the vehicle to sag or dip to any one side.
3.
The vehicle’s tires should not be noticeably deflated
4.
There should be no unnecessary or heavy loads inside the vehicle except for the driver.
5.
The headlamps should be cleaned, including any reflective areas around the lenses. The alignment head lens should also be free of any dirt or dust.
6.
The headlamp should be checked for burnouts, or condensation inside the lamp. If condensation is present, replacement of the lamp assembly is
recommended.
7.
Before setting floor slope, head should be set level using the level vial mounted on the aim screen. Move HBA5 to a
known level
surface
, and
proceed in leveling the head. Adjust the head level (left to right) by loosening and adjusting front eccentric axle until bubble appears in center of
level vial. Re-tighten axle and confirm level of head. You are now ready to set your floor slope.
3.2 FLOOR SLOPE ALIGNMENT
The floor slope adjustment must be performed to align the alignment head parallel with the slope of the floor. Improper floor slope adjustment
will result in improper headlamp alignment. NOTE: Floor rail must be used during floor slope adjustment IF floor rail is used during
headlamp alignment procedure.
