V ERTICAL C LEARANCE
Check the height of the area where the lift is to be
installed. Clearance should be calculated based on
the full raised height of the lift.
Failure by purchaser to
provide adequate clearance
could result in unsatisfactory
lift performance, property damage, or personal
injury.
F LOORING
Be certain you have the proper concrete floor to
properly handle the loaded lift. Floor should be in
generally good condition with no large cracks, spalling
or deterioration.
Minimum requirements for concrete are 4 inches
minimum depth, with steel reinforcement, 3500
psi, cured for 28 days per local commercial
practice. Floor should be level within 3/8 inch over the
installation area. No anchors should be installed
within 8 inches of any crack, edge, or expansion joint.
If these conditions cannot be met, a pad may be
poured to accommodate the lift.
Check with local building inspectors and/or permits
office for any special instructions or approvals
required for your installation.
A qualified person should be consulted to address
seismic loads and other local or state requirements.
Failure by purchaser to
provide the recommended
mounting surface could result
in unsatisfactory lift performance, property
damage, or personal injury.

LAYOUT
Note:
This lift can be installed at two different heights
and three different widths. The Cable adjustment
for the Height and Width variations will be
accommodated by the Lower Sheave Bracket.
The height and width must be established before
beginning, as this will determine the lower
sheave position.
1) Once the general location of the lift has been
determined, ensure that the proper conditions
exist per page 3.
2) Determine which side of the bay the power unit
will be located and identify the column assembly
with the power unit bracket.
3) Lay out the service bay according to the
architect’s plans or owner’s instructions (see Fig
1b–Service Bay Layout). Failure to install in this
orientation can result in personal and property
damage.
LIFT PREPARATION
4) With column assemblies lying flat, remove cable
and hose rolls from inside the column.
5) Manually push carriages up enough to unhook the
cylinder hose from the base plate tabs. Proceed
with pushing the cylinder and carriage up enough
to access all five sheave locations on the sheave
bracket, see Fig 3.

Model CL12A
Installation, Operation and Maintenance
Page 5
Rev. 01/23/2023
CL12-IOM-A.doc
6) Determine the sheave location on the lower
bracket based on the overall height and width of
the lift at its chosen configuration. Use the
General Specifications table from page 2 and
Fig 2 below.
Note: The column has been assembled with the
sheave in the highest position on the bracket for
the lift installed at max height and max width.

7) The sheave must be removed and reassembled
to route the synchronizer cable. Remove the bolt,
sheave pin, bearing disc, sheave, and spacer
bushing, Fig. 3.
8) Route a cable through a carriage and out the
bottom. Route it back up and into the inside hole
at the top of the carriage, see Fig 3. Ensure
cables do not twist or wrap around hoses
during routing.
9) Install a nut and jam nut at the cable end, Fig 3.
10) Reinstall the sheave. Place the bearing disc
inside the bracket centered over the bracket hole
based on the chosen install height. Install the
cable on the sheave and slide into place. Stack
the spacer bushing onto the sheave assembly.
Still holding the sheave assembly, slide the pin
into place and secure it with the bolt, see Fig 3.
11) Pull tension on the free end of the cable and
ensure proper routing. While pulling tension on
the cable, slide the cylinder and carriage down
until the carriage is 8” from the baseplate. Slide
the hydraulic cylinder down and route the
hydraulic hose around the hose guide tabs to
prevent rotation of the cylinder, Fig 4. While
pulling tension on the cable to avoid kinking, slide
the carriage and cylinder down to base of lift.

ANCHORING
The anchor bolts must be installed at least 8” from
any crack, edge, or expansion joint. Recheck the
area around both base plates.
Use a concrete hammer drill with a 3/4 inch carbide
bit. Tip diameter should conform to ANSI Standard
B94.12-1977 (.775 to .787). Do not use excessively
worn bits or bits, which have been incorrectly
sharpened. A core bit may be necessary if an
obstruction is encountered. Never substitute with
shorter anchor.
16) Recheck “Inside of Columns” dimension (Fig. 1).
17) Using the base plate as a template, drill one
anchor hole. Drill through the floor if possible or to
a depth of 5 inches minimum.
18) Clean the hole inside and out.
19) Assemble a washer and nut to the anchor with nut
just below impact section of bolt. Drive the anchor
into the hole until the nut is 3/4” above the
baseplate (leaving room for shims).
Complete steps 17 thru 19 for the six (6) exposed
anchors (one at a time) around each column.
20) Raise both carriages (275 lbs. ea.) high enough to
drill the two inner anchor holes on each column.
Measure both carriage heights to ensure they are
in the same lock position.
21) IMPORTANT:Place a safety support inside each
column as a backup to the locks, since the
hydraulic cylinders are no longer engaged with
the carriages.
22) Repeat steps 17 thru 19 for the two (2) anchors
under each carriage.
23) Shim both columns to plumb using the shims
provided as shown in Fig. 7. DO NOT shim more
than 1/2" at any given point. Use a level no less
than 24” in length to plumb columns.
24) Drive all the anchors until nut and washer contact
baseplate.
Fig. 7 – Column Shimming
25) Tighten Power Column anchors and recheck
column for plumb. Re-shim if necessary. Torque
to 150 foot pounds to set anchors.
26) Loosen Idler Column anchors 1/8” and proceed
with the Overhead Beam installation.
OVERHEAD
27) Before raising overhead into position install 4 (2
per column) hex flange bolts and nuts in bottom
hole of column extension (see Fig. 8 Installation
Aid) for temporary support of overhead. Lift
overhead assembly up into position and install
with 8 each (4 per column) 3/8”-16 x 3/4” lg. hex
flange bolts and hex flange nuts per side as
shown in Fig. 8. For the max width position, the
outer overhead holes will be used. For the (-6”)
width, use one set of outer overhead holes and
one set of inner overhead holes. For the (-12”)
width, use the inner sets of overhead holes.
Fig. 8 – Overhead Assembly
28) Check idler column shimming. Use additional
shims (see Fig. 7) to remove any gaps that may
have been created while installing overhead
beam. Tighten anchor bolts and re-check column
for plumb. Torque to 150 foot-pounds.

29) Attach the Overhead Limit Switch to the rear set
of holes on the Power Side of the Overhead
Beam using the hardware already attached to
the switch bracket, Fig. 9.
Fig. 9 – Overhead Limit Switch Power Side
30) Repeat for Idler Side – Attach the Idler Bracket
to the rear set of holes on the Idler Side of the
Overhead Beam using the hardware already
attached to the bracket, Fig. 10. Note the
orientation of the Idler Bracket. The narrow
slot needs to be facing towards the Power
Column.
Fig. 10 – Overhead Bracket Idler Side
31) Carefully insert the Shutoff Bar into the Power
Side Switch Bracket over the limit switch and pin
the Shutoff Bar to the Idler Side Bracket with the
10mm dia. x 55mm Lg. clevis pin & hairpin
cotter.

SYNCHRONIZER CABLES
32) Route the free end of a cable coming out the top
of the carriage up and over the upper sheaves and
back down the opposite side. Install a 3/8x3 cable
trapping bolt with a nut on each side of the
overhead support plate at each sheave, Fig. 11.
Do this for both cables.
Fig. 11 – Column Ext. Cable Trapping
33) Mount synchronizer cables to carriages as shown
in Fig. 12.

Hydraulics
IMPORTANT: To ensure proper hose fitting seal
without damage to the fitting follow this procedure
for each hose connection: Screw flared fitting on
finger tight. Rotate flared fitting 1 1/2 hex flats (90
deg.). Back the flared fitting off one full turn. Again
tighten flared fitting finger tight, then rotate flared
fitting 1 1/2 hex flats (90 deg.).
Fig. 13 – Idler Hose Routing & Hose Brackets
34) Install the Hose Guide Brackets and Hose
Support Tabs to both the Idler & Power Columns
using 1/4”-20NC x 3/4” lg. hex flange bolt and nut,
see Fig 13.
35) Uncoil Idler side hose and Overhead hose and
attach them together. Route the loose end up the
Idler Side column extension and attach to the
Hose Support Tab with a “P” Clamp, Fig. 13.
(Each hose clamp requires one 3/8”-16NC x 3/4”
lg. hex flange bolt and one hex flange nut.)
Remove slack and tighten the clamp.
36) Route hose across overhead through both Hose
Guide Brackets, Fig.13, and down through the
Power Side column extension. Do not attach
clamps to the Overhead Hose at this time.
37) Uncoil Power Column hose and loosely attach it
to the hydraulic tee fitting (in hardware box). Note:
CL12A-1 & CL12A-2 will require two extension
hoses (supplied) to be attached to the tee
fitting to extend the power column hose and to
the power unit to extend the power unit hose.
38) Bring the Power Unit Hose and Power Side Hose
up the column to the lowest available hole of the
column extension. Insert steel tubing end of the
Power Unit Hose into the extension (outside in)
and loosely connect to the tee. Leave the

FINAL ADJUSTMENTS
HYDRAULICS
68) Lower the lift to the floor and raise the lift
approximately one foot.
69) Start with Idler side first. Slowly and carefully
loosen the bleed plug on top of the cylinder just
enough to allow the entrapped air to escape.
Repeat for power side.
70) Raise lift 6 inches. Repeat step 69 until no air
comes out of cylinder.
71) Pressure test hydraulic system. Energize power
unit, raise lift to full rise and continue to run motor
for additional 10 seconds. (NOTE: pressure relief
will make a high pitch squeal sound for these 10
seconds.) Check hydraulic system for leaks.
72) Energize power unit again for 10 seconds. With a
clean rag, wipe down both cylinder rods. (The
cylinders are shipped with a small amount of clear
anti-corosive lubricant that will be forced out
through the wiper when the lift reaches full rise.)
If lubricant is not wiped clean from the
cylinder rod, the cylinder will apear to be
leaking.
SYNCHRONIZING CABLES
73) Raise lift and ensure carriages lower into same
lock position.
74) Adjust synchronizing cables so the tension is
equal in both cables and carriages are firmly
sitting on locks.
75) Cycle lift to ensure that latches operate
simultaneously. Adjust if necessary.
LOCK RELEASE
76) Lower lift to the floor and snap plastic cover over
Power Column lock assembly.
77) Pull and release Power Column lock release
handle while watching Idler Column lock. Adjust
lower threaded sleeve cable adjuster jam nuts on
Idler Column until Idler Column lock disengages
and engages fully. When properly adjusted, the
idler column lock should just come to rest against
the back of the column when engaged and fully
out against the tab when disengaged. Tighten
Idler Column lower tab jam nuts.
IMPORTANT: IF IDLER SIDE LOCK PAWL DOES NOT
FULLY DISENGAGE,DAMAGE MAY RESULT TO IDLER SIDE
CARRIAGE AND OR CABLE SYNCHRONIZING SYSTEM.
78) Tighten threaded sleeve cable adjuster jam nuts
and install lock release knob.
79) Tighten and trim wire ties.
80) Snap plastic cover over Idler lock assembly (align
release cable with notches in cover).
ARM PIN KEEPER INSTALL
81) Install the arm pin into the arm assembly and
carriage.
82) Raise lift high enough to gain access underneath
the carriage. Make Sure Lift Is In Locks Before
Proceeding.
83) Slide the provided washer onto pin up against the
inner bevel gear.
84) Install the provided retaining ring onto the pin with
tool, Fig 24.
Fig 24 –Arm Pin Keeper Install
FINAL CHECKOUT PROCEDURE
