2. Care must be taken as burns can result from touching hot parts
3. Do not operate equipment with a damaged cord or if equipment has been dropped or
damaged –until it has been examined by a qualified service person
4. Do not let a cord hang over the edge of the table, bench, or counter or come in contact
with hot manifolds or moving fan blades
5. Let equipment cool completely before putting away. Loop cord loosely around equipment
when storing
6. To reduce risk of fire, do not operate equipment in the vicinity of open containers of
flammable liquids (gasoline)
7. Adequate ventilation should be provided when working on operating internal combustion
engines
8. Keep hair, loose clothing, fingers, and all parts of body away from moving parts
9. To reduce the risk of electric shock, do not use on wet surfaces or expose to rain
10.Use only as directed in this manual. Use only manufacturer’s recommended attachments
11.ALWAYS WEAR SAFETY GLASSES. Everyday eyeglasses only have impact resistant
lenses, they are not safety glasses
Basic common-sense safety precautions should always be followed when installing, operating
and maintaining the lift as a risk of fire, electric shock, or injury may be present.
In addition:
1. Read and follow all safety instructions and decals included with the lift. Read and follow
all safety instructions in this manual. Read and follow the ALI "Lifting It Right" manual
(included with the lift). Always use the "Vehicle Lifting Points" reference guide when lifting
a vehicle. Insure all materials stay up to date(www.autolift.org/ )
2. Only trained and authorized personnel should position a vehicle and operate the lift. Do
not allow customers or bystanders to operate the lift or be in the lift area.
3. Inspect the lift daily. Do not operate if potential problems have been identified or lift
malfunctions. Do not operate if lift has damaged or broken components. Never walk or
work under the lift unless all safety locks are completely engaged.
4. Never overload the lift. The rated capacity decal is located on the powerpack column. The
hydraulic system on this lift is not designed to be a load holding devise. Mechanical safety
locks must be engaged before proceeding under the lift, with vehicle servicing, or system
maintenance. Never override operating controls. This is unsafe and will void the warranty.

5. Before driving a vehicle between the columns, position all arms to insure unobstructed
entry. Do not hit or run over arms as this could damage the lift and/or vehicle.
6. Use all 4 arms to raise a vehicle. Position all lift pads to contact vehicle manufacturer’s
recommended lifting points. Raise lift slowly until all pads contact the vehicle. Check all
pads for complete and secure contact with the vehicle. Check all arm restraints to insure
they are engaged properly. Check that vehicle is stable on the lift. Only after confirming
these procedures, raise the lift to desired working height.
7. Special care must be used when lifting pick-up trucks. Optional truck adapters may be
required to reach manufacturer recommended lifting points. Always use these lifting
points. Running boards and other installed accessories may also require optional
adapters. Insure contents of the cargo box will not affect vehicle balance while on the lift.
8. Important: Removal or installation of heavier parts can change the vehicle's center of
gravity on the lift resulting in a critical load shift. The vehicle may then be unstable. Plan
ahead for this possibility to insure continued safety and refer to the vehicle
manufacturer’s service manual for recommended procedures.
9. Always keep the lift area free of obstructions and debris. Clean up grease and oil spills
immediately.
10.Never raise a vehicle with passengers inside. Before lowering a vehicle, check the lift and

INSTALLATION PROCEDURE
See the Illustration and Parts Reference section of this manual for diagrams and parts lists
that will assist you during the installation process. Use these diagrams and parts lists
together with the following written instructions. Insure the lift installation complies with
ANSI/ALI/ALIS, Safety Requirements for Installation and Service of Automotive Lifts.
1. With columns laying on the ground (carriage side up), tightly fasten one column extension
to one column using bolts, washers provided (reference diagram #1). Use extra washer
if necessary to shim bolts to make it flush with inside of tower to clear sliders.
Use the appropriate bolt hole locations to achieve either a 148’’ (3759mm) or 138’’
(3505mm) inch overall height. Repeat this procedure with the second column. Note:
extended model has 172’’ (4369mm) overall height.
2. Layout all pieces of the overhead crossmember on the floor and fasten tightly together
using bolts, washers and nuts provided (reference diagram #4).
3. Identify all parts for overhead safety shut-off bar (reference diagram #4). Tightly fasten
these parts to overhead crossmember with bolts, washers and nuts provided.
4. Raise each column so that its baseplate is located on the floor marking you made earlier.
Confirm that baseplate angles and measurements between columns match lift
specifications. Use extreme caution to insure the columns do not fall over.
Secure baseplate of the most level column by installing only one anchor bolt.
5. For optimum safety, two installers should lift and secure the overhead crossmember to
both columns using bolts, washers and nuts provided (reference diagram #4). Hand tighten
all crossmember nuts and bolts. Final tightening is completed in step 9.
6. Using two 4 ft. levels and required shims, level each column vertically on all four sides
(reference diagram #5). Use extreme caution to insure the columns do not fall
over. IMPORTANT: When leveling each column using anchor bolts provided, do not use
more than 3/4 inch (19 mm) of shims under any area of the baseplate. Use a 4 ft. level to
confirm the overhead crossmember is also level and at 90 degrees to both columns.
7. Drill and install all anchor bolts, washers and nuts (reference diagram #5). Insure that
each nut is torqued to 150 ft-lbs (204N-m). This should be checked monthly.
8. One equalizing cable comes partially installed on each carriage. Before feeding a cable up
its column to the overhead crossmember, insure the cable is properly seated around the
lower pulley at the base of each column (reference diagram #6). Route each cable up its
column, over the appropriate pulleys in the overhead crossmember, and lower it down to
the opposite carriage. Insure both equalizing cables are properly seated in overhead
crossmember pulleys. Thread one nut to its farthest point on each equalizing cable. Insert
threaded end into appropriate location on the carriage. Install and hand tighten second
nut to secure each cable. Final equalizing cable adjustment is step 17. Install two bolts
and nuts to prevent unintentional cable displacement.
9. Completely tighten both sides of the overhead crossmember to its column.

13
10.Identify component parts for the safety release cable. Install safety release cable so that
safety locks in both columns will completely disengage when lift is lowered. Final safety
release cable adjustment is step 16.
11.Identify parts to install arms (reference diagram #11). Install all 4 arms and arm pins.
Secure each arm pin by inserting roll pin provided. Adjust arm restraint to make sure it
works properly.
12.Install rubber mounts on powerpack bracket (reference diagram #13). Keep these rubber
mounts between the powerpack and the mounting bracket
13.Identify parts for hydraulic system installation (reference diagram #12). Tightly fasten
hydraulic lines to "T" fitting. Locate "T" assembly in overhead crossmember and route
the appropriate lines to cylinders and powerpack. Tightly fasten all hydraulic lines and
secure these lines to both columns and overhead crossmember using hardware. Insure
that nothing will rub or wear the hydraulic lines.
14.NOTE: this should be performed by a licenced electrician. Attach microswitch to
overhead safety bar bracket on powerpack side of overhead crossmember. Wire overhead
safety bar micro-switch to the powerpack. Wire powerpack to shop electrical system.
15.Fill powerpack reservoir with ISO 32 hydraulic oil. Make sure black venting plug is
attached at the top of the reservoir. Attach red plug at the bottom of the
reservoir.
16.Operate the lift with no vehicle and no other weight. Raise lifting carriages
approximately 30 inches (760mm). Confirm that safety locks on both sides engage
properly while lift is being raised. Verify that both lifting cylinders are properly seated in
the baseplate locator hole. Continue raising lift to full height confirming safety locks are
engaging. Adjust safety release cable to insure safety locks can be completely disengaged
while lowering lift (reference diagram #7). Insure that no people or obstacles are near the
lift when adjusting the safety release cable. Lower lift completely. Raise and lower the
lift at least three times or until all air in the hydraulic system is removed.
17.After confirming that all air has been bled from the hydraulic system, adjust equalizing
cable tension as follows: (also reference diagram #6).
Step 1) Hold top of threaded stud with a wrench to prevent it from rotating.

14
Step 2) Tighten nut "B" until all loose slack is removed from the cable. Do not over
tighten.
Step 3) Firmly tighten nut "A" to lock cable in place. Repeat this process for the other
cable insuring both cables have the same degree of tightness.
18.Raise lifting carriages approximately 12 inches (300mm) off the floor. Choose one arm
and align arm restraint gear with locking plunger insuring both components mesh
smoothly and totally. Completely tighten all arm restraint gear locking bolts to maintain
this position. Lower carriage to the floor to insure arm restraint disengages in the down
position. Raise the lift 12 inches (300mm) off the floor to insure arm restraint engages
smoothly and totally. Repeat this process with the remaining 3 arms. Raise and lower
the lift once more to confirm all arm restraints totally engage and disengage smoothly.
19.Install safety lock cover on each column (reference diagram #14).
20.The installation is now complete. Insure that all lift operators are trained in all
points covered by ALI-WL101 label kit (they are applied at the factory).
