OPERATING CONDITIONS
Lift is not intended for outdoor use
and has an operating ambient temperature
range of
41°-104°F (5°-40°C)

1. Lift Location: Use architects plan when available to
locate lift. Fig. 1 shows dimensions of a typical bay layout.
WARNING
DO NOT install this lift in a pit or
depression due to fire or explosion risks. A forklift is
recommended to upright each column during installation.
Note: Installation tip - Upright each column after installing
column extensions, column ties, and overhead brackets.
Check to verify both columns are greased with Tuffoil
Lightning Grease at slider block points of contact inside
the columns (see greasing locations in Fig. 3). If columns
are not greased with Tuffoil Lightning Grease, apply at
greasing locations specified.

2. Lift Setting: Position columns in bay using dimensions
shown in Fig.1. Place column with power unit mounting
bracket on vehicle passenger side of lift. Both column
base plate backs must be square on center line of lift.
Notches are cut into each base plate to indicate center
line of lift.
Use appropriate equipment to raise carriage to first latch
position. Be sure locking latch is securely engaged.

Concrete and Anchoring: Drill (14) 3/4" dia. holes (7 per side) in concrete floor using
holes in column base plate as a guide. See diagrams for
hole depth, hole spacing, and edge distance requirements.
CAUTION
DO NOT install on asphalt or other similar
unstable surfaces. Columns are supported only by
anchors in floor.
Run nut down just below
impact section of bolt. Drive
anchor into hole until nut and
washer contact base.
Drill holes using 3/4” carbide
tipped masonry drill bit per
ANSI B212.15-1994 (R2000).

FOUNDATION NOTES:
1. THE FOUNDATIONS HAVEBEENDESIGNED BASEDON APRESUMPTIVE LOAD-BEARING VALUE OF 1500 PSF
PERIBC SECTION 1806. AN INSPECTOR OR SOILS ENGINEERSHALL VERIFY LOAD-BEARING VALUE CAPACITY.
2. FOUNDATIONS SHALL BEARON PROPERLY PREPARED AND COMPACTED SOILS CAPABLE OF SUPPORTING
ROTARY LIFT LOADS.
3. PROTECT EXISTING UTILITIES AND STRUCTURES (OVERHEADOR UNDERGROUND) WITHIN THE WORK
AREA AS WELL AS ANY EXISTING FOUNDATION SYSTEM(S).
4. FOUNDATIONS WERE DESIGNED UTILIZING KBCSECTION 1605 'ALTERNATIVE BASIC LOAD COMBINATIONS'
WITHOUT THE 1/3 INCREASEIN THE ALLOWABLE BEARING PRESSURES DUE TO SHORT-TERM LOADING.
5. FOUNDATIONS SHALL BE PLACED ACCORDING TO THE DEPTHS SHOWN ON THE DRAWINGS. SHOULD SOIL
ENCOUNTERED AT THESEDEPTHS NOT BE APPROVEDBY THE INSPECTOR OR SOILS ENGINEER,

NOTE: If more than 2 horse shoe shims are used at any of
the column anchor bolts, pack non-shrink grout under the
unsupported area of the column base. Insure shims are
held tightly between the baseplate and floor after torquing
anchors.
7. IMPORTANT: Using the horse shoe shims provided,
shim each column base 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 N774-1Shim). Recheck columns for
plumb. Tighten anchor bolts to an installation torque of 110
ft-lbs. Shim thickness MUST NOT exceed 1/2” when using
the 5-1/2” long anchors provided with the lift, Fig. 6.
If anchors do not tighten to 110 ft-lbs (149 Nm) installation
torque, replace concrete under each column base. See
Figs. 6a and 6b.
NOTE: FIG. 6a and 6b were taken from drawing SPEC0476.

A) To install cylinder, first slip dampening spacer over rod
with rod in retracted position as shown below, Fig. 16.
B) Put locknut on threaded shaft and run it down to the
dampening spacer.
C) Let rod extend and thread locknut down 1-1/2 more
turns.

locknut securely, Fig. 16.
E) Slide latch control plate into top cylinder Bracket
Clevis.
F) Insert Pivot Pin through hole in bracket and Latch
Plate. Install one clip ring on each side of Upper Pin.
G) Extend cylinder where column Pivot Bracket is to be
mounted.
Note: Absence of air filter/regulator/lubricator will
void the warranty on all pneumatic components.
H) Slide one side of lower Pivot Pin (pre-installed & fixed
in cylinder) into one half of the column Pivot Bracket.
Install Pivot Bracket into column using (2) 1/4"-20NC x
3/8" lg. PHMS, Fig. 16.
I) Install other half of Pivot Bracket the same way.
J) Install air lines from main air supply (with filter) to
latch release air valve. Install air line from lathch
release air valve to union tee then to the right column
air cylinder.
K) Install air line from union tee to left column air cylin-
der, Fig. 18.

Locking Latch Engagement Test:
A) Raise carriages past the first latch position and then

B) Check that the latches have fully engaged when the
release switch is not depressed.
C) Raise carriages fully off latches. Now depress release
switch and check that the latches have fully disen-
gaged.
D) Check for air leaks, make necessary adjustments or
repairs if required.
E) Install latch covers with 5/16"-18NC x 3/8" lg. PHCS, Fig.
17.
Note: Cut provided tubing with sharp blade to length
as required. Tubing must be cut square with no burrs.
To assemble air line tubing into fitting, use firm, manual
pressure to push tubing into fitting until it bottoms, see
below. If removal of the air line tubing from the fitting is
ever required, hold Push Sleeve in (against fitting) and
at the same time, pull out on tubing.

14. Electrical: Have a certified electrician run appropriate
power supply to motor, Figs. 19 and 20. Size wire for 20
amp circuit. See Motor Operating Data Table.
CAUTION
Never operate the motor on line voltage less
than 208V. Motor damage may occur.
IMPORTANT: Use separate circuit for each power unit.
Protect each circuit with time delay fuse or circuit breaker.
For single phase 208-230V, use 20 amp fuse. For wiring see
Figs. 19 and 20. All wiring must comply with NEC and all
local electrical codes.
Note: 60Hz. single phase motor CAN NOT be run on 50Hz.
line without a physical change in the motor.
15. Overhead switch: Check overhead switch assembly
to assure that switch bar is depressing switch plunger
sufficiently to actuate the switch. The overhead switch is
wired normally open, see Fig. 20. Lift will not operate until
weight of switch bar is depressing switch plunger. Verify
that Power Unit stops working when switch bar is raised,
and re-starts when the bar is released.
CAUTION
When bleeding, hold a shop cloth over
bleeder screw to buffer the air and fluid while bleeder-
valve is open.
16. Oil Filling & Bleeding: Use Dexron III ATF, or
Hydraulic Fluid that meets ISO 32 specifications. Remove
fill-breather cap, Fig. 20. Pour in (8) liters of fluid. Start
unit, raise lift about 2 ft. Open cylinder bleeders approx. 2
turns, Fig. 13.
Close bleeders when fluid streams. Torque values for the
bleeders are 15 ft. lb. minimum and 20 ft lb. maximum. Fully
lower lift. Add more fluid until it reaches fill line on the
tank. System capacity is (14) liters. Replace fill-breather
cap.
CAUTION
If fill-breather cap is lost or broken, order
replacement. Reservoir must be vented.
