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


● 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.


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 installed 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.

Lift operation by authorized personnel over 18

years only.

Apply the parking brake after positioning the vehicle on

the lift.

Do not allow anyone to stay in lift area during raising

and lowering cycles. Closely watch the vehicle and the lift

during raising and lowering cycles.

Observe the rated load capacity and load distribution Do

not allow anyone to climb on lift or stay inside vehicle.

After raising the vehicle briefly, stop and check adapters

for secure contact.

lift you must press the lowering lever to relieve the

hydraulic pressure and let the latch set tight in a lock

position.

5. MAINTENANCE SCHEDULE

The following periodic maintenance is the suggested

minimum requirements and minimum intervals;

accumulated hours or monthly period, which ever comes

sooner. If you hear a noise or see any indication of

impending failure-cease operation immediately-inspect,

correct and/or replace parts as required.

WARNING-USERS SHOULD ALWAYS

INSPECT LIFTING EQUIPMENT AT THE START OF

EVERY SHIFT. THESE AND OTHER PERIODIC

INSPECTIONS ARE THE RESPONSIBILITY OF THE

USER.

5.1 DAILY PRE-OPERATION CHECK (8

HOURS)

Always lock the lift before going under the

vehicle. Never allow anyone to go under the lift when

raising or lowering. Read the safety procedures in the

manual.

The user should perform daily check.

ATTENTION! LOOK OUT! Daily check of safety latch

system is very important - the discovery of device failure

before needed could save you from expensive property

damage, lost production time, serious personal" injury

and even death.

Note: It is normal for an empty lift to lower

slowly. It may be necessary to add weight.

4.4 Lowering

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.
