Lift Table Operation
:
Take reasonable precautions to avoid the
obvious potential hazards
of using a cart:
1. Instruct other persons in the area to stand at a safe distance while raising or lowering the deck. Be certain no
part of any person, clothing, or object is under any part of the cart before lowering the deck.
4. DO NOT transport a load with the deck in the fully raised position. Always transport loads with the deck fully
lowered. Transport the load to the unloading point, and then raise the deck to the necessary height. After
unloading the cart, fully lower the deck.
5. Do not over-tighten the release valve!
To raise the deck:
1. Make sure that the release valve is closed by turning the release knob
clockwise until it is tight.
2. Step on the brake lever to apply the caster brake. (Fig. 9)
3. Put the load on the deck using the “L
OADING
” instructions on p. 10.
4. Turn the pedal to Position 2 (see below Fig. 9).
5. Pump the pedal with your foot and continue to do so until the deck reaches the
desired elevation. The table has an upper travel limit; the deck will not rise
above ~33 inches.
[NOTE: If the table is unloaded, you may use the high speed option for raising the
deck. Turn the pedal to Position 1; then pump the pedal until the desired deck
position is achieved.]
To lower the deck: slowly turn the release knob counterclockwise to open the release valve. The deck will lower
more rapidly the farther you turn the knob. Do not let the deck descend rapidly, but rather allow the deck to slowly
lower to the fully lowered position. Once the deck is fully lowered, close the release valve by turning the release
knob clockwise. [NOTE
:
The hydraulic system cannot pressurize, and the deck will not rise in response to
pumping the pedal, if the release valve is open. Always make sure to turn the knob clockwise after the deck is
fully lowered to close the valve.]
The cart is manually propelled. After loading the cart and properly securing the load to the deck, push the cart to
the desired location. Do not exceed a rate of two feet per second when transporting a load with the cart.
Hydraulic system operation:
Hydraulic components are all rated for 2,500 psi working pressure.
Key components and specifications of the hydraulic system include:
Check valve: prevents backflow of fluid through the pump. It allows the deck to hold a given elevation.
However, leaks in the system will cause the deck to lower over time.
Pressure relief valve: opens a path for fluid to follow to the reservoir if the fluid pressure exceeds a
threshold (maximum).
Safety velocity fuse: installed in the housing connected to the cylinder. It closes automatically if a
catastrophic hose failure occurs, and closing the fuse prevents the lift table from collapsing. The velocity
fuse is designed to slowly lower the deck by allowing gradual depressurization of the hydraulic system.
2 Pump Speeds: To raise the deck, pump the pedal with your foot. 2 speeds are available for raising the
deck. When the pedal is in position 1, the deck will rise at a faster rate; in position 2, the deck rises more
slowly. To switch between speeds, rotate the handle.
Release/Lowering Valve: turn the release knob to lower the deck.
2. DO NOT use the cart if:
(a) You notice any damage or hear
unusual noise(s) while raising or
lowering the deck;
(b) It requires maintenance or repairs;
- OR -
(c) The cart malfunctions in any way.
Tag the cart “Out of Service” and
immediately notify your supervisor or
maintenance personnel.
3. DO NOT park on or push the cart
across inclined surfaces. Drive the
cart straight up or straight down
inclined surfaces. The load may shift
while traversing an incline, so
secure the load to the deck, for
example with straps, BEFORE
attempting to drive the cart over the
incline. ALWAYS push the cart
up/down an incline.
