Hydraulic
Elevating Carts
Description
Portable ergonomic elevating carts minimize worker bending and lifting.
Materials can be easily loaded onto platform of cart, lowered to safe transporting
height, and raised to unload at destination. Moves easily on four polyurethane
caster; two swivel with brake and two rigid. All models feature a down speed
control valve, internal hydraulic velocity fuse in each cylinder and an exclusive
automatic two-speed manual hydraulic foot pump. All steel construction. Powder
coated red finish. Failure
to follow the proper operating instructions could result
in iajury.
After receiving a hydraulic elevating cart, visually inspect the frame components
and hydraulic
unit for damage. If damage is evident, notify delivering carrier
immediately and file necessary claims.
S Tcations and Dimensions
I
General Safety Information
1. Not a personnel lift. Keep clear
when operating.
2. Never go under platform if there is
weight on the unit.
3. Remove weight before working on
unit.
4. Use only maintenance parts
supplied
or approved by the
manufacturer.
5. Do not change pressure relief valve
setting.
6. Do not clamp cylinder in a vise as
you may distort barrel.
7. Never operate lift unless you are
watching it.
8. Load lift as uniformly as possible.
9. Consult factory for uneven loading.
10. Do
not continue to pump if unit is
not raising.
11. Relieve system pressure by slowly
operating pressure release
mechanism.
12. Consult
factory if any modifications
are going to be made.
.13. Do
not use brake fluids or jack oils.
Use AW-32 or hydraulic oils.
Assembly
TOOLS REQUIRED: (2) 9/16 in box end
wrenches
After unpacking the cart locate the
handle and the hardware to install it.
Line
up the mounting holes on the
handle with the holes in the frame and
install and
tighten the bolts. Your cart
is now ready for use.

Foot Pump Operation
Your new lift equipment has been
supplied
with our exclusive 2-speed
foot pump. The initial features of
your pump includes a primary
pressure relief, pressure compensated
return flow control valve, and an
integrated lowering valve.
Replaceable bushings, valve
components, and seals have been
utilized in the construction of the
pump in the event that replacements
are necessary.
Stay clear
of moving parts. The
platform will rise as the foot pedal is
pumped. Depressing the lowering
valve will lower the table at a
controlled rate of descent.
In
the event the platform has been
overloaded,
the pressure relief will
open because of excessive pressure
buildup in the hydraulic system. Oil
will bypass into the reservoir. NEVER
change the pressure relief setting. DO
NOT exceed
the rated capacity of your
lift equipment.
SPEED SELECTION FOR TWO-SPEED
PUMPS
This pump offers two "speeds".'The
low speed setting produces low
volume/high pressure. The high speed
setting produces high volume/low
pressure. The operator has the option
of selecting the optimum pump speed
for the application at hand. Pump
speeds are selected
by sliding the
"lock collar" (See below) in or out. An
occasional drop of oil will keep the
collar working freely.
AIR BLEED PROCEDURE
Whether your pump is a new
installation, or has been recently
serviced,
air has likely entered the
hydraulic system. The design of this
pump includes an "air bleed screw"
which will aid in the removal of
unwanted air from the foot pump area
of hydraulic system. Use the following
steps to remove this air from the
system.
1. Check all
fittings to be sure they are
tight. Ensure that the oil is filled to
within 1" of the top of the reservoir
when the lift is in the fully lowered
position.
2. Locate the "air bleed screw" (see
figure 3} and loosen approximately
1/2 turn counterclockwise. As soon
as you have loosened the screw,
slowly depress
the foot pedal. This
will force the air out of the pump
chamber. Before you let the pump
pedal return to the "up" or "home"
position, tighten the air bleed screw.
This
will prevent air from reentering
the pump chamber. Repeat the
above procedure until the pump
chamber is completely filled with oil
and a "spongy" feel is no longer
present. If the air bleeding
procedure has been successful, the
feel the of the pump pedal will be
firm and the complete stroke of the
pump will produce fluid flow.
LOAD COLLAR
LOWERING VALVE
Maintenance
AlI bushings and bearings are of the
pre-lubricated type and will last for a
long period of time without additional
lubrication. Tb increase bearing life, it
is recommended that a few drops of
light machine oil be applied at each
pivot point every 6 to 12 months.
DAILY
Visually check and do not use if any of
the following are visible:
1. Oil Leaks.
2. Structural deformation of legs or
frame.
3. Unusual noise or binding
4. Check casters for proper operation.
MONTHLY
1. Check for oil leaks.
2. Check clevis and pivot points for
wear.
3. Check rollers for looseness and wear.
4. Check for unusual noise.
5. Make sure all warning labels are in
place and in good condition.
6. Clean off dirt and debris.

YEARLY
Hydraulic
oil should be changed at
least once a year, or sooner if the oil
darkens or becomes gritty. Flush
reservoir
before refilling. Presence of
water is indicated if the oiI turns milky.
Recommended oil: AW-32 hydraulic
fluid or equal.
All maintenance
work must be
preformed by qualified personnel with
training in the repair of electrical and
hydraulic components.
NOTE:
If hydraulic oil is milky white in
color, water is in the hydraulic system.
Change
the hydraulic oil immediately.
TO FILL UNIT WITH OIL
1. Raise the platform and block the leg
assembly
in the fully raised position.
2. Remove the upper cylinder pin.
3. Loosen the set screw in the lowering
rod linkage.
4. Release the lowering valve.
5. Collapse the cylinder rod back inside
the cylinder.
6. Remove the oil fill plug.
7. With the cylinder horizontal, fill
with AW-32 grade hydraulic oil (or
equivalent).
8. Reinstall the fill plug, and then
reinstall the cylinder.
TO BLEED SYSTEM
1. Ensure
platform is in lowered
position.
2. Operate the lowering mechanism
and pump the foot control several
times slowly.
TO FILL WITH OIL LOW OIL
CONDITION
1. Raise the unit as far as it will go.
2. Remove the oil fill plug.
3. Add oil 1 oz. at a time.
4. Pump the foot control.
5. Repeat steps 3 and 4 until the unit's
maximum height is achieved.
6. Once the maximum height is
reached, add 1 oz. of oil and
reinstall the fill plug.
IF CART LEAKS
DOWN
1. Completely lower the platform. By
hand, grasp the deck at the hinge
end of the leg assembly. Raise the
deck as high as possible, then
3
carefully, while standing aside, allow
the assembly to drop. This procedure
draws oil through the load holding
check valve and "washes" debris (if
present) from the ball and seat of
the device. It may be necessary to
repeat this procedure a couple of
times to remove all debris from the
check valve thus, eliminating table
drift.
2. Check the oil level in the pump
assembly. The oil should be level
with the bottom of the hole with
the scissor legs in the lowered
position. (Deck tilts up).
NOTE:
If these steps fail to return the
unit to service, contact supplier for
further instructions.
