3.1 IMPORTANT CONCRETE AND
ANCHORING INFORMATION
● Concrete shall have compression strength of at least
3,000 PSI and a minimum thickness of 4" in order to
achieve a minimum anchor embedment of 3 1/4”.
When using the standard supplied 3/4” x 5 1/2” long
anchors, if the top of the anchor exceeds 2 1/4” above
the floor grade, you DO NOT have enough
embedment.
● Use the existing holes in column base plate as a guide
for drilling the 3/4” diameter holes into the concrete.
Maintain a 6” minimum distance from any slab edge
or seam. Hole to hole spacing should be a minimum 6
1/2” in any direction. Concrete thickness or hole depth
should be a minimum of 4”.
CAUTION: DO NOT Install on asphalt or other
similar unstable surface. Columns are supported only by
anchoring in floor.
● Using the horseshoe shims provided, shim each
column base as required until each column is plumb.
If one column has to be elevated to match the plane of
the other column, full size base shim plates should be
used (Reference Shim Kit). Torque anchors to 120 ft-
lbs. Shim thickness MUST NOT exceed 1/2” when
using the 5 1/2” long anchors provided with the lift.
Adjust the column extensions plumb.
● If anchors do not tighten to 150 ft-lbs. Installation
torque, replace concrete under each column base with
a 4' x 4' x 6" thick 3,000 PSI minimum concrete pad
keyed under and flush with the top of existing floor.
Let concrete cure before installing lifts and anchors.
3.2 ANCHORING TIP SHEET
11 Aston® Overhead Two Post Lift AL-100RH User’s Manual
● Anchors must be at least 6” from the edge of the slab
or any seam.
● Use a concrete hammer drill with a carbide tip, solid
drill bit the same diameter as the anchor, 3/4”. (.775
to .787 inches diameter). Do not use excessively worn
bits or bits which have been incorrectly sharpened.
● Keep the drill in a perpendicular line while drilling.
● Let the drill do the work. Do not apply excessive
pressure. Lift the drill up and down occasionally to
remove residue to reduce binding.
● Drill the hole to depth equal to the length of anchor.
● For better holding power blow dust from the hole.
● Place a flat washer and hex nut over threaded end of
anchor, leaving approximately 1/2 inch of thread
exposed carefully tap anchor. Do not damage threads.
Tap anchor into the concrete until nut and flat washer
are against base plate. Do not use an impact wrench to
tighten. Tighten the nut, two or three turns on average
concrete (28-day cure). If the concrete is very hard
only one or two turns may be required. Check each
anchor bolt with torque wrench set to 120-foot pounds.
3.3 INSTALLATION PRECEDURE
PLEASE READ THIS INSTRUCTION
BEFORE STARTING TO OPERATE THE LIFT.
Check for ceiling clearance first to confirm the
lift can be set up in your bay.
STEP 1: After unloading the lift, place it near the intended
installation location.
STEP 2: Remove the shipping bands and packing
materials from the unit.
STEP 3: Open the wrapping from the upper column and
carefully remove the parts from inside. Remove the
packing brackets and bolts holding the two columns
together (do not discard bolts, they are used in the assembly
of the lift)
STEP 4: Position the columns facing each other 107-1/4”
inside base plates Square the columns by measuring
diagonally from corner points on base plates (within 1/4”).
STEP 5: Using a 3/4" concrete drill, drill the anchor holes
in the main side column, installing anchors as you go. Use
a block of wood or rubber mallet to drive anchor bolts in.
Drill to a minimum depth of 4" to insure maximum holding
power. Drilling thru concrete (recommended) will allow
the anchor to be driven thru the bottom if the anchor needs
to be replaced later.
STEP 6: Using a level, check column for side-to-side
plumb and front-to-back plumb. If needed, use horseshoe
shims provided by placing shims underneath the base plate
and around the anchor bolt. This will prevent bending the
column bottom plates (Shim thickness should not exceed
1/2”). Tighten anchor bolts to 120 ft-lbs.
STEP 7: Install the overhead cross beam. Be sur e to bolt
them together by installing the bolts from inside the cross
beam out. This is to avoid interference with the cable when
operating the lift. Next, install the cross beam between two
columns.
STEP 8: After fastening the cross beam, check and
confirm that the remaining column is plumb.
STEP 9: Secure the remaining column by duplicating
STEP 6 and STEP 7.
STEP 10: Install the safety latch on both side columns. Connect the safety release cable between two latches.
12 Aston® Overhead Two Post Lift AL-100RH User’s Manual
Check that the tension of the cable is tight. Pull the single
point release handle several times and check the tension
again by making sure both latches release at the same time
when the handle is pulled.
STEP 11: Mount the power unit on the main side leg to the
power unit bracket using the four 5/16” bolts and nuts.
Connect the power unit to the fitting in- stalled on the back
of the main leg by using a short hose supplied.
STEP 12: Connect the equalizing cables. Do not tighten at
this stage of assembly.
NOTE: The cable stud that connects to the front
right corner of the carriage should be connected first by
pulling the stud through the carriage hole and up where
it is easy to be held by locking pliers. Pull the stud back
into place after threading at least 1/2” of the stud past the
locknut. Connect the other ends to the rear right corners
of the carriage with at least 1/2” of thread showing past
the lock nut (cables run on the inside of the carriage). It
may be necessary to manually raise both carriages above
the cylinder to provide enough space to use the locking
pliers. Make sure the carriage is set in the LOCK position.
STEP 17: Locate each hole in the center of the up-rights,
approximately 6” below the top edge, on the same side of
the columns as the power unit. Install the two eye-bolts to
the outside of each up-right with the hardware provided.
STEP 18: Insert the cable through the eye-bolt in the slave
column side and secure with crimp fitting. Run cable across
to the motor column side through the eye-bolt and down to
the motor. Insert cable through the pull-pin on top of the
motor and temporarily secure with locking pliers or small
clamp.
Operate lift and apply pressure to the safety cable to insure
motor shuts off prior to any part of vehicle coming in
contact with cross rail.
Adjust cable if necessary and secure with crimp fitting. Remove any excess cable with wire cutters.
STEP 19: Do not place any vehicle on the lift at this time.
Cycle the lift up and down several times to insure latches
engage properly and all air is re- moved from the system.
To lower the lift, first raised the lift to clear the latches and
then pull down the safety release handle to lower lift. lf
latches function out of sync, tighten the cable on the latch
that engages first.
STEP 13: Adjust the carriage cable tension. This is 4. OPERATION
accomplished by tightening the carriage adjustment nut on top of each carriage. The rear carriage adjustment nut
adjusts the opposite post carriage height. The left post
carriage nut adjusts the right column carriage, and the right
column carriage nut adjusts the left column carriage.
Adjust each cable to approximately 1/2” side-to-side play.
Check the latch releases to insure the carriage is still
engaged in the appropriate latch.
STEP 14: Install all four swing arms, readjust the arm lock
preinstalled to make sure that gear racks are engaging the
moon gear on the arm properly.
STEP 15: Remove the vent plug from the power unit and
fill the reservoir. Use a Ten Weight (SAE-10) non-foaming,
non-detergent hydraulic fluid (Texaco HD46 or equal). The
unit will hold twelve quarts of fluid.
STEP 16: Make the Electrical hookup to the power unit.
Warning: the wiring must comply with local
code. Have a certified electrician make the electrical hook
-up to the power unit.

LIMITED WARRANTY
Structural Warranty:
The following parts and structural components carry a three-year warranty: Arms, Columns, Carriages, Legs,
Overhead Beam, Tracks Cross Rails, Top Rail Beam, Swivel Pins, Uprights
Limited One-Year Warranty:
Aston® offers a limited one-year warranty to the original purchaser of Lifts in the United States, Canada and
Mexico. Aston® will replace, without charge, any part found defective in materials or workmanship under
normal use, for a period of one year after purchase. The purchaser is responsible for all shipping charges. This
warranty does not apply to equipment that has been improperly installed or altered or that has not been operated
or maintained according to specifications.
Other Limitations:
This warranty does not cover: 1. Parts needed for normal maintenance. 2. Wear parts, including but not limited
to cables, slider blocks, chains, rubber pads and pulleys. 3. Replacement of lift after the first 30 days. A seal kit
and installation instructions will be sent for repairs thereafter. 4. On-site labor: Upon receipt, the customer must
visually inspect the equipment for any potential freight damage before signing clear on the shipping receipt.
Freight damage is not considered a warranty issue and therefore must be noted for any potential recovery with
the shipping company.
The customer is required to notify Aston® of any missing parts within 72 hours. Timely notification must be
received to be covered under warranty. Aston® will replace any defective part under warranty at no charge as
soon as such parts become available from the manufacturer. No guarantee is given as to the immediate
availability of replacement parts.
Aston® reserves the right to make improvements and/or design changes to its lifts without any obligation to
previously sold, assembled or fabricated equipment.
There is no other express warranty on the Aston® lifts and this warranty is exclusive of and in lieu of all other
warranties, expressed or implied, including all warranties of merchantability and fitness for a purpose.
To the fullest extent allowed by law, Aston® shall not be liable for loss of use, cost of cover, lost profits,
inconvenience, lost time, commercial loss or other incidental or consequential damages.
This Limited Warranty is granted to the original purchaser only and is not transferable or assignable. Some
states do not allow exclusion or limitation of consequential damages or how long an implied warranty lasts, so
the above limitations and exclusions may not apply. This warranty gives you specific legal rights and you may
have other rights, which may vary from state to state.
