Operating a hydraulic pump in
reverse, even for brief periods,
can cause permanent pump
damage.
Before securing the unit to the
floor, shim or grout the entire
base frame assembly.
Continuous base frame support
is essential for proper
installation.
SECTION 4. INSTALLATION INSTRUCTIONS
Floor mounted units:
1. Move the lift to the usage area, insure the floor is clean and level prior to final placement. If
slings are used, encircle the entire lift, not just the platform.
2. Apply proper voltage to the equipment, using the pushbutton control or footswitch, push the
“up” button in short jogs to see if the lift will rise.
If the unit does not rise, check the motor rotation.
On 3- phase systems, swap any two of the three
power wires to reverse the motor rotation.
3. Raise the lift halfway several times then fully
lower it, holding the down control an extra 10
seconds each time the lift is lowered to bleed air
from the unit.
4. Lag the unit in place using ½” x 5”, “Rawl-Studs” or wedge anchors in the holes provided.
5. Clean any debris or spilled fluid as they may later
be misinterpreted as mechanical trouble or a
hydraulic leak. While highly unlikely, it may be
necessary to tighten some hydraulic fittings due to
the rigors of shipping. Remove maintenance
device(s) and lower the unit.
6. Instruct user(s) in the proper operation of the lift,
safety precautions, and equipment capacity. Supply maintenance personnel with this service
manual.
Pit mounted units:
1. Check all pit dimensions for accuracy.
2. Attach a temporary electrical line through the pit conduit to the lift. Check for correct motor
rotation; (see paragraph 2 in “floor mounted installation”).
3. Using slings, encircle the entire lift, not just the platform and lower the lift into the pit,
centering it for 1” minimum clearance on all sides to the pit wall.
4. Raise the lift with the pushbutton or footswitch and remove the slings. Run the unit up and
down several times to remove air from the hydraulic system.
5. Level and center the lift by shimming and grouting the entire base frame, not just the
corners. Lag the unit in place using ½” x 5”, “Rawl-Studs” or wedge anchors in the holes
provided.
6. With the lift fully elevated, disconnect the main power and complete the permanent electrical
wiring.
7. Follow the instructions outlined in paragraphs 5 and 6 under “Floor mounted installation”. To
complete the installation.
P 4-1

SECTION 5. OPERATING INSTRUCTIONS
Hydraulic scissors lifts have an excellent safety record overall but as with all moving
equipment they can be dangerous. Operators must use common sense and take
responsibility for the safety of everyone near the lift. They must use the safety devices
provided and be careful not to surprise anyone in the area with the movement of the lift.
Pre-operational checks:
1. Check all electrical wiring and connections to be sure that they are completed
properly and are operational.
2. Check for obstructions or debris that may interfere with the safe operations of the lift.
3. Be sure that all personnel in the area are a safe distance away from the lift and
aware that you are about to operate it.
4. If there are any optional safety devices such as bellows or electric toe guards, check
them for proper operation.
Test operating the equipment:
1. Station yourself so that you will always see the equipment when it is in operation.
Never operate the equipment blind.
2. Raise the equipment and note that the control is a constant pressure, “dead-man”
type. When you release the up or down switch, the unit should stop moving
immediately and maintain its elevation. If it does not, contact your maintenance
personnel.
3. Cycle the equipment several times to be sure that it is operating smoothly with no
jerking or sudden movement. On initial startup, there may be some air in the lines or
the cylinders may be dry due to storage so it may take several cycles to smooth out
the operation. If the operation is not smooth after several cycles, contact your
maintenance personnel. Immediately stop using the lift if there is any evidence of
binding or scraping in the operation.
4. Check all safety devices for proper operation.
5. If you elect to test load the equipment be sure that you do not exceed the capacities
shown on the nameplate. Overloading may cause structural stresses that may not
show up for some time, but will diminish the life and capacity of the unit. If you have
any questions about testing the unit, call our customer service department at 1-800-
843-3625.
Daily operation:
1. All personnel shall be required to read the entire operating instruction sections
(Sections 3 & 5) of this manual prior to operating the lift.
2. Operators must know the capacity of the unit and be aware of any loads that may
exceed the capacity.
P 5-1

Operators must be alert to personnel in the vicinity of the lift.
Avoid any surprises to these personnel in regard to movement
of or the position of the lift. Never operate unit if you cannot
see it and the personnel around it.
SECTION 5. OPERATING INSTRUCTIONS (CONTINUED)
Daily operation (continued):
3. On the first use of the lift each day, the operator shall check to see that the lift is
functioning properly and smoothly. All safety devices shall be in place and operating
correctly.
4. If the unit has a traveling electrical cord, the operator must insure that it is kept away
from the lift as it raises and lowers.
5. Loads shall be centered before raising or lowering the lift as this will help insure
even wear on all moving parts
P 5-2

SECTION 6. MAINTENANCE INSTRUCTIONS
General Information Notes:
1. Always remember that machinery with large moving parts can seriously injure you.
2. Read and understand this manual before attempting any service work.
3. Always use the maintenance device(s) when working on the unit in the elevated
position or reaching under the platform. (See photos 6-1, 6-2, 6.3 and 6.4 at the end
of this section for proper positioning and engagement of the maintenance device(s)).
4. When using the maintenance device(s), adhere to the following rules:
A. The unit must be unloaded.
B. Be sure the maintenance device(s) are properly engaged.
C. Depress the “Down” button or foot pedal for an extra 10 seconds when lowering
onto the maintenance device(s), to be sure that all the weight of the lift is on the
device and hydraulic pressure is relieved.
D. Disconnect and tag the electricity to the unit to prevent accidental movement of
the lift by other personnel. Follow all applicable lockout/tag out procedures.
E. Spend as little time as possible under the lift.
5. Only use replacement parts recommended by the manufacturer.
6. Do not let the equipment stay in disrepair; fix small problems before they become big
problems. A unit in disrepair can become a severe hazard if left unattended.
7. Inspect the equipment on a regular schedule, preferably monthly.
8. Never work on the hydraulics or electrical systems unless the unit is fully lowered or
properly sitting on the maintenance device(s).
9. Never apply a load to the equipment until the base frame is continuously supported.
10.The only safe way to hold a lift’s legs open is the factory designed maintenance
device(s).
P 6-1
Never expect to hold the leg assemblies open by simply lifting one end of a
platform. The roller end of most lifts is not “gibbed” or captured in any way.
Lifting the roller end will simply tilt the platform. Even if you raise the clevis
end of the platform, if the base frame is not firmly lagged to the ground or
held down by some other means, the legs will come up with the platform in
an unpredictable manner and could cause personal injury.

Before performing any service under
the lift, make certain the
maintenance devices are in place per
the instructions in this document.
SECTION 6. MAINTENANCE INSTRUCTIONS (CONTINUED)
Routine Maintenance: (All lifts)
Weekly: Raise the lift to its full height. This will get rid of cylinder oil seepage buildup
and lubricate the upper cylinder barrel. On all units, this fluid will be returned to the
reservoir via the breather lines.
Monthly:
1. Check the hydraulic fluid level.
When checking fluid levels, make
sure the unit is in the full-up position,
with the maintenance device(s) in
place.
2. Clean all debris from the vicinity of
floor and pit mounted units in order to avoid interference with the lift mechanism or
rollers.
3. Check for presence and proper seating of all snap rings and clips on all axles,
cylinder and rollers.
4. Check rollers, pins and bushings for any signs of wear such as flat spots, missing
fasteners, or dislodged bearing material.
5. Check the hydraulic fittings for cracks or leaks and clean up any weepage on or
beneath the cylinder.
6. Check hoses and electrical lines for abrasions or other abuse and check for snug
connections.
7. Operate the unit and check for any abnormal noise or vibrations.
8. Check all safety devices on the unit such as the condition of the pleated bellows or
smooth operation of the electric toe guards.
Seasonal or Semiannual Maintenance: Change hydraulic fluid for ambient
temperature change if appropriate or if there is any evidence of accumulated
condensation creating water contamination. See page P 6-1, “General Information
Notes” for more information on changing fluid.
P 6-2

Always use the maintenance device(s) for any service or maintenance. Never go or
reach under the lift unless the maintenance device(s) are securely in place and the
power to the unit has been disconnected to prevent others from operating the lift.
Never use the maintenance device(s) with a load on the platform.

RELIEVE ALL HYDRAULIC PRESSURE
BEFORE DISASSEMBLING HYDRAULIC
COMPONENTS. THE SUDDEN
DISCHARGE OF HIGH PRESSURE OIL
COULD CAUSE INJURY.
SECTION 8. HYDRAULIC DETAILS
1. Weepage and Leakage:
A. All hydraulic cylinders will require the replacement of seals after a period of time
depending on usage and environmental conditions. It is considered normal
maintenance. However, maintenance personnel shall recognize the difference
between leakage and weepage.
B. Weepage is the normal accumulation of fluid that passes the seals in the course
of operations, as the hydraulic fluid properly performs its lubrication function on
cylinder walls and piston rods. It may be occasionally observed squirting from
cylinder breathers, but should stop squirting after several cycles of full stroke
when the small accumulation is cleared.
C. Leakage is the fluid, which leaks past worn or cut seals. It too may be observed
squirting, but does not stop after several cycles and the lift will probably not hold
position under load.
D. All units have breather lines that return any weepage or leakage of fluid from the
cylinder to the reservoir. It is important that the return lines do not get pinched or
kinked or they may dislodge from the fittings.
E. Always be careful when working around cylinders, not to nick the extended rod or
dent the cylinder housing, as this may cause damage to cylinder seals.
F. If you elect to repaint any part of the lift, cover exposed rods with plastic or
soluble grease, which can be removed after painting to insure that no paint sticks
to the rods and damages the seals.
2. General precautions:
A. Be sure that all pressure is
relieved from the hydraulic
system before disassembling
any components. Continue to
hold the “down” control for
several seconds after fully
lowering the unit on its maintenance device(s) or the ground, before opening a
hose line or hydraulic component.
B. Always be careful to avoid contamination entering the system. Be especially
careful with the ends of hoses, which may fall into oil dry, or dirt. If you suspect
contamination, flush the system and components.
3. Hydraulic fittings, sealant and torque’s:
A. Advance Lifts may be equipped with either NPT fittings (tapered), or SAE fittings
(with O-ring seals), or JIC fittings (37-1/2˚ tapered). Know the difference.
B. Be careful when tightening NPT fittings not to over-tighten and crack them.
Swivel fittings are especially vulnerable and shall only be tightened enough to
stop leaking.
C. If leakage persists after tightening the fittings fairly hard, inspect fittings for burrs
on the mating edges or the possibility of a 37-1/2˚ SAE fitting being mixed with
30˚ NPT fittings or either one being mixed with SAE 45˚ fittings.
P 8-1

SECTION 8. HYDRAULIC DETAILS (CONTINUED)
D. When using Teflon tape on NPT fittings, be sure the tape is started 1-1/2 threads
back from the leading edge and only use 2 wraps to be sure that tape does not
break off and contaminate the system. You may substitute pipe sealant with
Teflon paste from “Pro Lock” or “Loctite”, but again do not over apply. Never use
sealant or tapes on JIC, O-Ring Boss or swivel fittings.
E. Be extremely careful not to over-tighten ORB fittings, thread the fitting finger tight
and then tighten the jamb nut on the fitting.
F. Never reuse old Teflon tape. Once a connection has been opened, remove all
tape and apply fresh tape.
OIL RECOMMENDATIONS AND SEAL COMPATIBILITY
Fluids:
1. The current standard hydraulic fluid is a multi-viscosity ISO-46 group II base oil
hydraulic fluid. This is the fluid normally supplied by the factory and is suitable for a
temperature range of –10 to +100 degrees Fahrenheit. When replacing or adding
fluid to an Advance Lift, use only ISO 46 hydraulic fluid that is manufactured with a
group II base oil. ISO 46 hydraulic fluid is normally clear; we have the fluid dyed
purple for better visibility.
2. Unless approved by the Advance lifts, do not use any other fluid. Brake fluids and
other hydraulic fluids may damage the system’s seals or hoses. If it is required to
switch from one fluid to another, drain the reservoir and system completely, and then
refill with the new fluid.
3. Biodegradable and fire retardant fluids are available. Contact the factory for
specifications. It may be necessary to change some seals and/or hoses for total
system compatibility, depending upon the specific model lift and the requested fluid.
Options:
For extremely warm temperature ranges of 120º to 140º degrees Fahrenheit, you
may switch to 10W30 motor oil. If ambient temperatures are expected above 140º
degrees, consult the factory.
For extremely cold temperature ranges, Advance Lifts recommends the use of a fluid
heater, contact your distributor for more information and specifications.
Seals:
Generally, the seals in the unit are Buna-N-Nitrile and polyurethane. The hoses are
either PVC for suction lines or braided wire for pressure lines. Always call the factory
about special fluids rather than make assumptions on your own.
