2. Using the baseplate on each column as a guide,
drill each anchor hole approximately 4-1/2” deep
using a rotary hammer drill and 3/4” concrete bit.
( See Fig. 5 )
3. After drilling, remove dust thoroughly from each
hole using compressed air and/or wire brush. Make
certain that the columns remain aligned with the
chalk line. Always wear safety goggles.
4. Assemble the washers and nuts on the anchors
then tap into each hole with a hammer until the
washer rests against the baseplate. Be sure that if
shimming is required, enough threads are left
exposed. ( See Fig. 6 )
5. If shimming is required, insert the shims as
necessary under the baseplate so that when the
anchor bolts are tightened, the columns will be
plumb. ( See Fig. 7 )

safety lock failure. AIR PRESSURE SHOULD BE REGULATED TO 125 PSI MAX. ( See Fig. 13 )
Fig. 13

STEP 10
( Power-Unit Start Up )
1. Have a certified electrician run 208 - 230 volt
single phase 60 HZ power supply to motor. ( If you
ordered optional three phase power refer to the
data plate found on the motor for proper power
supply. ) Be sure to size wire for a 25 amp circuit.
RISK OF EXPLOSION!
This equipment has internal arcing or parts that
may spark and should not be exposed to
flammable vapors. Motor should not be located in
a recessed area or below floor level. NEVER
expose motor to rain or other damp environments.
DAMAGE TO MOTOR CAUSED BY WATER IS
NOT COVERED UNDER WARRANTY.
STEP 11
( Lift Start Up )
1. Make sure the power unit reservoir is full with
15 quarts of 10-WT hydraulic oil or Dexron-III
automatic transmission fluid.
2. Spray the inside of the columns where the slide
blocks glide with a light lubricant or WD-40.
3. Test the power unit by depressing the push-
button switch. If the motor sounds like it is
operating properly, raise lift and check all hose
connections for leaks.
IF MOTOR GETS HOT OR
SOUNDS PECULIAR, STOP IMMEDIATELY AND
RE-CHECK ELECTRICAL CONNECTIONS.
4. Once the lift starts to raise, simultaneously
press the power unit lowering handle at the same
time you are pressing the raise button. This will
allow any air trapped in the cylinder and lines to
escape and vent into the fluid reservoir.
5. Continue raising the lift slowly until all the slack in
the cables is taken out.
RAISE THE LIFT UNTIL
THE CYLINDER BOTTOMS OUT AND THE LIFT
STOPS. ADJUST EACH CABLE SO THAT THE
SAFETY LOCKS REST AT ONE INCH ABOVE
THE TOP SAFETY LOCK POSITION.
It may be
necessary to tighten or loosen each cable to reach
the proper height. The nylon cable nuts MUST be
tightened on each end until there is at least 1/4” of
threads through the nylon end of the nut.
STEP 12
( Installing Slack Safety Springs )
The following steps involve the SLACK CABLE
SAFETY DEVICE and MAIN SAFETY. Failure to
follow these steps could result in serious injury
or death in the event of cable failure.

on the REAR CROSS TUBE as shown. Make
sure spring ends are secure at both ends. ( See
Fig. 14 )
12
IMPORTANT NOTE:
DO NOT USE 110 VOLT POWER SUPPLY for
this power unit. damage to motor will occur which
is not covered under warranty. You must use a
separate circuit breaker for each lift.

13
2. Check all MAIN SAFETY LOCKS to make sure
they move freely and spring back to the lock
position when released.
3. Lubricate all SAFETY PIVOT points with
WD-40 or equal.
STEP 13
( Final Assembly )
1. Tighten the cable adjusting nuts on the top of
each column and at the cylinder flange until all
remaining safety locks raise to one inch above the
top lock position. This will ensure that the cables
are adjusted evenly.
The nylon cable nuts MUST be tightened on
each end until there is at least 1/4” of threads
through the nylon end of the nut. Failure to do
so could result in serious injury or death.
2. After connecting the air supply, press the PUSH
BUTTON AIR VALVE and check that all safety
locks are functioning properly, then lower the lift
by pressing the push button air valve and power
unit lowering valve simultaneously.
NOTE:
There will be some initial stretching of the
cables in the beginning. It will be necessary to
re-adjust the cables a week after first use, then
every three to six months thereafter.
3. Run the lift up and down a few times to insure
that the locks are engaging uniformly and that the
safety release mechanisms are functioning
properly. Re-adjust if necessary.
4. Install the front tire stops. ( See Fig. 15 )
5. Install the approach ramps on the entry side of
the lift. Drive a vehicle onto the lift making sure to
set the emergency before exiting the vehicle.
