MANUAL CARTS (CART-LP-2000-####-FP)
USING THE CART (FP UNITS)
All loads applied to the deck must be centered and evenly distributed. Loads
should not overhang the deck, i.e. should be entirely contained within the deck area.
The capacity of the cart appears on the data label of your unit. See
label 287 on
. Capacity is the maximum
net
weight the cart can
support. Exceeding the capacity could result in personal injury and/or the cart might
be permanently damaged.
Elevate the cart by pressing and releasing the pump pedal. Pump the pedal as
many times as necessary to achieve the desired deck elevation. Lower the deck by
pressing the release lever. Transport loads with the deck lowered. Elevate the deck
to an ergonomic height when removing loads or working on an item. See Autoshifter
instruction manual for detailed instructions about the operation of the foot pump.
Apply the caster brakes whenever the cart is stopped. See diagrams in
INSPECTIONS AND MAINTENANCE (FP UNITS)
section on p. 8-9. Push down on
the brake lever to apply the brake. Lift the release lever to disengage the brake.
BLEEDING AIR FROM HYDRAULIC SYSTEM (FP UNITS)
If the deck lowers extremely slowly or not at all when the release
lever pressed, air might be caught in the cylinder. Air causes a safety
feature called a velocity fuse to close. When the velocity fuse is
closed, the deck will not lower. To correct this issue, bleed air from
the system. A bleeder screw is located at the top of the cylinder. The
bleeder screw includes a hose fitting for a small diameter hose. By
attaching a hose to the screw, any oil that escapes during the
bleeding process can be directed into a container for proper disposal.
To bleed air from the cylinder:
1.
Raise the deck. Deploy the maintenance prop.
2.
Lower the deck until it is supported by the maintenance prop.
3.
Pump the foot pedal once.
4.
Slowly open the bleeder screw by turning the hex head counterclockwise.
Pressure generated by pumping the pedal causes air and oil to flow out of the
bleeder screw. Pressure will drop as air and oil flow from the cylinder. To
repressurize the system, close the bleeder screw and pump the pedal just
once. Open the bleeder screw again to allow more trapped air to escape.
Repeat this process until air is completely removed from the cylinder (i.e. only
oil flows from the bleeder screw).
5.
Check all of the hydraulic lines for oil leaks.
6.
Close the bleeder screw and return the unit to service.
RECORD OF SATISFACTORY CONDITION (FP UNITS)
Before putting the cart into regular service, make a record of its appearance and operation. Pay particular attention
to pivot points and pivot point hardware. Cycle the deck up and down. Describe the motion of the legs and roller.
Describe the sound of the foot pump as it operates. Also include a description of the cylinders as they extend and
retract. Each CYLINDER should extend and retract smoothly and at the same rate as the other. Photograph the cart
from multiple angles. Include close range photographs of deck rollers, labels, casters, and the maintenance prop. This
record establishes normal condition. During future inspections, compare observations to the record to determine if a
component is in normal condition. DO NOT use the cart unless it is in satisfactory condition.
INSPECTIONS AND MAINTENANCE (FP UNITS)
Inspections and repairs should only be performed by qualified
persons. Compare the results of each inspection to the
SATISFACTORY CONDITION (FP UNITS)
. Do not use the cart
unless all parts are in satisfactory condition. Replace parts that are
not in satisfactory condition before returning the cart to service.
DON’T GUESS!
If you have any questions about the condition of
your cart, contact the
department.
The
phone number is provided on the cover page of this manual.
Never
make temporary repairs of damaged or missing parts
. Only use
manufacturer-approved replacement parts.
