SECTION 1
INTRODUCTION
The Presto XZ and TZ Series Lift models are designed for lifting and/or tilting and positioning a
wide variety of loads. Each lift is provided with an entrance ramp allowing easy access to the lift
and also acts as a safety toe bar for the operator during the lowering cycle. The XZ and TZ Series
Lifts are designed for indoor non-hazardous location use.
This manual provides information necessary for the safe and proper installation, operation and
maintenance of these lifts. It is important that this manual be read by all personnel involved with
the installation, maintenance or operation of the scissor lift. Where unique situations arise, which
are not covered in this manual, contact Presto Lifts, Inc. for further instructions. Additional manuals are available upon request.
The floor level lifts have a nameplate that provides the load capacity ratings, serial number and
model identification. Please refer to these numbers when ordering parts or requesting further information.
CAUTION!
Hazard or unsafe practice possibly resulting in personal injury or property damage.
SECTION 2
SAFETY
The XZ and TZ Series lifts are very powerful lifts capable of doing large amounts of work. They are hydraulically actuated and capable of causing serious injury or damage if adequate precautions are not taken.
DO NOT INSTALL OR OPERATE THESE LIFTS WITHOUT CAREFULLY READING THIS MANUAL. Presto Lifts, Inc. has identified certain hazards which may occur during the installation, maintenance
and use of these lifts.
The TZ Lifts are serviced or repaired in the collapsed position. The XZ lifts are serviced in a raised position supported by safety devices. When the maintenance is performed properly according to Sections 5
and 6, it will greatly reduce the possibility of injury. Both the XZ and TZ lifts have hydraulic safety fuses
attached to each cylinder. These will prevent the lifts from lowering in the event of a catastrophic hydraulic
pump or line failure.
DANGER – Immediate hazard that will result in severe personal injury or death.
WARNING – Hazard or unsafe practice that could result in severe personal injury or death.
CAUTION – hazard or unsafe practice that could result in minor personal injury or property damage.
In the interest of safety, please read the entire manual carefully. You must understand the material in this manual before you install, use, or service the unit. If you have any question about
any of the instructions in this manual, please contact Presto Lifts Inc. at 1-800-343-9322.

flat, stable, relatively smooth and free from dirt,
obstacles or surface defects.
b. Place the lift in the exact operating position using a
sling attached to all four lifting eyes.
CAUTION!
When moving the lift never ever attempt to pick
it up by the corners or the base. The lift should
be picked up only by the lifting eyes. The use of
a spreader strap/sling is suggested. Be sure that
the eye bolts are secured in place with locking nuts
prior to lifting.
INSTALLATION
c. Make sure that the complete base of the lift is in
contact with the floor. In order to provide complete contact with the floor, the base may be
shimmed or grouted.
A. INSPECTION:
Inspect the lift completely to determine if there is any
damage that occurred during shipment and that the
lift is complete. Do not use the lift if there appears to
be any damage. Check the following with the lift in
the collapsed position:
CAUTION!
Do not spot shim. The complete base must be in
contact with the floor. Shim to have continuous
contact of base and floor.
SECTION 3
1. Check for signs of damage to the electrical and hydraulic components of the remote power pack. Check
the hydraulic hoses going to the lift and the hydraulic
components on the lift.
2. Check all connections for tightness. Check for visible hydraulic fluid around all components of the lift
and power pack or on the floor nearby.
3. Check base frames for flatness and for bent or damaged metal parts.
4. Inspect the lifting eyes making sure they are completely threaded into the nuts provided on the lift and
the locking nut is secured.
d. The lift is provided with lag plates or brackets.
Place the lift in the exact operating position before spotting or drilling holes for the bolts. Bolt

C. ELECTRICALS:
1. The motors on the XZ and TZ power pack are intermittent duty motors with high pull up torque.
CAUTION!
All wiring must conform to local code and must be
performed by licensed electricians. The standard
AC single phase motor requires a 120 volt 20 amp
fused outlet, do not remove or replace the plug or
cord set provided. Do not use an extension cord.
2. The following chart recommends the power source
for various motors supplied with the XZ and TZ lifts:
AC Motor Size

See Figure 9 for 208-480 Volts 3 PH
WARNING!
Do not tamper with or remove the cover for the
electrical junction box. Only authorized qualified personnel are allowed to service the electrical
system.
WARNING!
Failure to make electrical connections according
to nameplate ratings and wiring diagrams may
lead to pump and motor failure. The 3 phase
motor direction is most critical. The pumps can
not be run backwards or in reverse for more than
three (3) seconds. If lift does not rise immediately.
STOP. Inspect connections for correct wiring and
polarity.
D. HYDRAULICS:
with the vented plug provided. If the vented plug is
not installed, you may damage the pump. Note: If
the vented plug is not available, remove the solid plug
and drill a 1/8” diameter hole through the center of
the plug. Replace the plug.
2. Use hydraulic oil only for the lift. The lift has been
supplied with Conoco Super Hydraulic 32. Use only
the recommended oils lifted in the hydraulic schematic located in the rear of this manual in Figure 10.
WARNING!
Do not use automotive hydraulic brake or transmission fluids. They will destroy the pump and
cylinder seals. They pose a serious fire hazard.
3. External power pack units are shipped connected.
If disconnection is required during installations,
the lines must be blown out and bled prior to being
reconnected.
CAUTION!
The XZ and TZ lifts are designed for normal factory environments. Where below freezing temperatures sometimes exist, special oils must be used.
Contact Presto Lifts, Inc. for information and
recommendations when freezing conditions exist.
E. TESTING THE LIFT WITH NO LOAD:
1. Before testing the lift, clear the area of any loose
material. Be sure the lift has no obstructions above it
or on any side. Briefly operate the lift for 2-5 seconds. If the lift begins to rise with a humming sound
and functions properly, continue to the full upright
position.
WARNING!
If the lift does not rise immediately or there is any
operational problem, stop it. Before continuing,
check the rotatin of the motor and the voltage at
motor terminals. Again, briefly operate the lift. If
the lift does not move smoothly with the humming
sound, stop and review the procedures in Section
5C, Troubleshooting Maintenance.
1. Before using the lift, check the hydraulic oil level
and add oil if necessary. Check fittings for tightness.
Remove the solid plug on the reservoir and replace it
Page 6 — PRESTO OWNER’S MANUAL: XZ, XZT FLOOR LEVEL LIFTS & TZ FLOOR LEVEL TILTS
SECTION 4
OPERATION
A. METHOD OF OPERATION:
All XZ and TZ lifts are provided with a relief valve
and are factory preset to the maximum safe load
capacity of the lift. Activating and holding the
upswitch will energize the motor. The motor is attached to a positive displacement pump which draws
hydraulic fluid from the reservoir and transfers it
under pressure to the cylinders. This forces the ram
forward and raises or tilts the platform. Releasing the
up switch will stop the lift. A check valve built into
the pump holds the lift in position. Depressing and
holding the down switch of the switch will energize
a solenoid which allows the oil from the cylinder to
return to the reservoir through a pressure flow control
valve and the pump. This allows the lift to lower
smoothly and at a controlled factory preset speed.
WARNING!
Do not maintain the switches energized if the lift
does not move or has reached its up or down limits. This may cause damage to the motor, pump
and controls.
B. OPERATION PROCEDURES:
In order to operate the lift, follow these operating
procedures:
3. Operate the lift.
a. To raise the lift, press and hold the up switch.
b. To lower the lift, press the down switch.
c. Release the switch to stop the lift in either direction.
4. Wait until the lift has come to a complete stop
before loading or unloading.
5. All people and unrelated objects must stand clear
of the lift when operating in order to avoid personal
injury or property damage.
WARNING!
a. Do not load or unload a moving lift.
b. Stop immediately if the lift fails to move or
exhibits strange movements or sound. Do not continue to operate the lift until it has been checked
and repaired.
c. When operating the lift, stand clear of the scissor legs and the platform.
d. Obey all warning labels.
e. Do not stand near the tilting side when tilting
containers with loose parts. Parts may fall out of
the container and could harm the operator.
1. Read and understand all the instructions before
operating. If the lift has modifications or accessories,
read and understand their functions. Review Section
3E and Pinch Points figures 3, or 4 and 5.
2. Load the lift correctly.
a. Do not exceed the maximum rated load capacity.
The load capacity is marked on the data place on
the left.
b. Place the load in the center and at the very back of
the platform.
c. If the load is unstable or may become unstable,
fasten it into position.
d. Use additional precautions when tilting a load of
loose parts of the TZ lift. Excessive tilting can
cause parts to roll out.

Table 1 – Hydraulic Oil Specifications
If the lift will be used at normal ambient temperatures, Presto Lifts supplies the unit with
Conoco Super Hydraulic 32 oil. This may be replaced by any other good quality oil with
150 SSU at 100° F and rust and oxidation inhibitors and anti-wear properties.
If the lift will be used at ambient temperatures below 0°F, use aircraft hydraulic oil. Use
Type 15 aircraft hydraulic oil.
The following are equivalent to Conoco Super Hydraulic 32:
TYPE
MANUFACTURER
AW32 ................................. CITGO
DTE 24 ............................. EXXON/MOBIL
NUTO H32 ........................ EXXON/MOBIL
AMOCO AW32 .................. CHEVRON (AMOCO CO.)
CAUTION!
It is very important to keep the hydraulic oil free of dirt, dust, metal chips, water, and
other contamination. Most of the problems with hydraulic systems are caused by
contamination in the oil.
