INSTALLATION
A. UNCRATING AND INSPECTION
Upon receipt of the Double Scissor Lifts, inspect the equip-
ment completely to determine if there is any shipping damage,
and that the lift is complete. Presto-ECOA tests and inspects
every piece of equipment prior to shipment. If damage is ap-
parent, a freight claim must be filed with the freight company.
Do Not use the lift if there appears to be any damage. With
the lift in a collapsed position, check the following:
NOTICE
Lifts with oversize table tops must not be over extended
since doing so may disassociate the cylinder base from
its socket. (See Section 5, Maintenance).
1. Check for signs of damage especially to the
electrical and hydraulic components.
2. Check all connections for tightness.
3. Check for any bent or damaged metal parts.
4. Check base frame for flatness.
NOTICE
When moving the lift, do not attempt to pick it up by the
table top. The lift should be picked up by its base only.
B. INSTALLING
Before starting, be sure that the electrical system is wired
and is in full compliance with local electrical codes and ordi-
nances. Read all of the instructions prior to starting the lift.
1. Handle Assembly
Portable lifts have the push handles removed for
ease of shipping. Handles should be inserted in the
holders until they bottom out then tighten set screws
on each holder with an Allen wrench.
2. Floor Installation
Electrical connections must be made according to
the electrical schematics and information contained
in Section 3C and in compliance to local codes and
ordinances.
C. ELECTRICALS
1. The motors on Double Scissor Lifts are special intermittent
duty motors with high pull up torques. These motors require
heavier duty electrical controls than standard motors.
2. Wiring circuits must conform to local codes and must be
installed by a licensed electrician.
3. Lifts are pre-wired at the factory for motor direction and
performance.
CAUTION!
All wiring must conform to local codes and must be
performed by licensed electricians.
WARNING!
Do not attempt to modify or change the electrical circuit.
Any alterations will cause damage to the pump and pos-
sible physical injury. Only authorized personnel should
service the electrical system.
4. For the XS, DXS or WXS Series Scissor Lifts, a dedicated
circuit of 20 amps or larger will suffice to operate the lift.
D. HYDRAULICS
1. Use only hydraulic oil for the lift. The lift has been supplied
with Conoco Super Hydraulic 32. When adding fluid, use only
the recommended oils. See Table 1.
2. Before using the lift, check the hydraulic oil level and add
oil if necessary. Check fittings for tightness. If the plug is not
installed, you may damage the pump.
NOTICE
Double Scissor Lifts are designed for normal factory en-
vironments. Where below freezing conditions may exist,
special fluid must be used. Contact Presto-ECOA Lifts
for further information 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 obstruction above it or on any side.
2. Using the controls provided, briefly operate the lift (5-10
seconds). If the lift begins to rise with a humming sound and
functions properly, continue to the full upright position.
NOTICE
If the lift does not rise immediately, or there is any op-
erational problem, stop it immediately. Before continu-
ing, check the rotation of the pump and motor and the
