GENERAL
ASSEMBLY
INSTRUCTIONS
Step 1 Insert Front Eccentric Axle assembly (eccentric without scale). Rotate eccentric axle until small scribe mark aligns with indicator arrow on base.
Tighten mounting screws.
Step 2. Insert Floor Slope Eccentric Axle assembly (attached indicator scale & handle). Tighten mounting screws.
Step 3. Place flat washer on 5/16”-18 x 2.5” bolt and push bolt through hole inside of base. Secure bolt in place using one 5/16” steel flat washer and non-
locking nut. Tighten until bolt is secure. Place one thin 5/16” nylon washer on bolt, followed by wheel, additional nylon washer and locking 5/16”
nut. Tighten locking nut until wheel is snug but spins freely.
Step 4. Lay the wheelbase flat on floor. Place the nylon thrust bushing over the hole in the center of the wheelbase. Holding the mast upright, place the stud on
the bottom of the mast through the bushing and into the hole in the center of the wheelbase. Tilt the wheel-base and mast together until you can access
the large hole on the bottom of the wheelbase. Place the provided1/2” flat washer and self-locking nut on the stud, and tighten to zero tolerance.
Loosen 1/16 turn at a time until the mast rotates smoothly with slight resistance.
Step 5. Remove attachment screw at top of mast spring cover.
Step 6. Slide Glide Plate over end of mast, between mast and mast spring cover, ensuring that handle is pointed away from spring cover. Slide glide plate
down over mast until the spring hook of the glide plate is even with the bottom of the spring inside of the mast spring cover. Place bottom of spring
into spring hook, and reattach screw at top of mast spring cover.
NOTE:
Four (4) tension adjustment set screws are located on the glide plate, two (2) are visible on the outside of the glide plate and two (2) are
located on the side that is covered by the spring cover. If glide plate becomes loose, or is overly tight during assembly, these tension
screws can be loosened/tightened for optimum operation and smoothness.
NOTE:
Lightly lubricate mast with light-weight oil for smooth movement of glide plate.
DO NOT
lubricate side of mast that has the brake
mechanism, if oil is place on this side of mast, brake could loose friction properties during use.
Step 7. Place Mirror Assembly on top of mast, and attach using two ¼”-20 x 1 ½” Allen head cap screws with 1/4” washers, insuring that mirror extends out
on the same side of the mast as the glide plate. Tighten the locking nut until the mirror is held tight, but is allowed to turn with slight resistance.
Step 8. Mount the HBA5 Head to the glide plate with four ¼”-20 button head cap screws.
Step 9: Remove viewing window (window is attached with tape during shipment) and packet of attachment screws. Attach battery to terminal and adhere to
side of head with supplied Felcro fastener. Replace window and attach with supplied screws.
Step 10. Place Laser on top of HBA5, unit assembly is complete. NOTE: The laser is to be removed from the head when floor slope calibration procedure is
NOT being performed.
Step 11. Battery must be initially charged for 12 hours prior to first use for optimum performance.
1.2
BASE / MAST CALIBRATION
Step 1:
Verify that scribe mark on eccentric axel is aligned with arrow on base.
Calibration Complete
IF NOT
Step 2:
Locate a level surface area and place HBA 5 in this area.
Step 3:
Lower HBA 5 alignment head to its lowest point.
Step 4:
Loosen bolts on front eccentric wheel (1).
Step 5.
While viewing level vial, located on the aiming screen, rotate the front eccentric wheel until level vial is centered.
Step 6:
Tighten bolts on front eccentric wheel, recheck level vial for center. Calibration Complete.
1..3 MIRROR CALIBRATION PROCEDURE
Step 1:
Standing at the rear of the alignment head (opposite the lens,) note the black calibration points on top
at front of the alignment head.
Step 2:
Turn mirror down until the mirror’s line and the calibration points on the alignment head can be clearly viewed
in mirror.
Step 3:
Line up the calibration points, and the mirror line
Step 4:
If the mirror line and the calibration points are not parallel, slightly loosen the mirror mount
bolts on the top of the mast.
Step 5:
While viewing the calibration points through the mirror, push or pull the mirror until the line
in the mirror is parallel with the points on the alignment head.
Step 6:
Tighten the mirror mount bolts, holding the mirror firmly in place.
Step 7:
Re-check the mirror and alignment head calibration points to ensure they are both parallel.
