Using the Table:
All loads applied to the tabletop 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 table appears on the data label of your unit
(see label 287 on p. 13). Capacity is the maximum
net
weight the table can
support. Exceeding the capacity might result in personal injury and/or the
table could be permanently damaged.
Elevate the tabletop by pressing and releasing the foot pedal. Pump the
pedal as many times as necessary to achieve the desired tabletop elevation.
Lower the tabletop by pressing the release lever. (See Autoshifter instruction
manual for detailed instructions about the operation of the foot pump). Elevate
the tabletop to an ergonomic height before removing loads or to work on an
item.
Bleeding Air from Hydraulic System:
If the tabletop lowers extremely slowly or not at all when the release lever is 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 tabletop
will not lower. To correct this issue, bleed air from the system. A bleeder screw is located at the top of the cylinder
(see appropriate “Exploded view” on pages 4-11). 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 tabletop and deploy the maintenance prop (see diagram in “Inspections and Maintenance” section).
2.
Lower the tabletop until it is entirely supported by the maintenance prop.
3.
Pump the foot pedal once.
4.
Slowly open the bleeder screw. 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 step
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.
Inspections and Maintenance:
Before putting the table into regular service, make a written record of its appearance and operation. Pay particular
attention to pivot points and pivot point hardware. Use the foot pump to cycle the tabletop up and down. Describe the
motion of the legs and rollers. Describe sounds heard as the tabletop moves. Also include a description of the
cylinders and pistons as they extend and retract. Each piston should extend and retract smoothly and at the same
rate as the other. Indicate how much force is required to pump the foot pedal and to press the release lever. 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 table unless it is in normal condition.
Before inspecting or performing maintenance on the table, immobilize the tabletop with the maintenance prop.
1. Unload the table.
2. Raise the tabletop to its maximum height.
3. Rotate the maintenance prop into contact with the
frame (see dotted arrow).
4. Press the release lever and lower the tabletop until the
maintenance prop presses against the end of the
frame.
(A) Before each use, check the table for any of the
following conditions.
Oil
leaks;
Pinched or chafed hoses;
Deformation of legs, frame, or tabletop;
Unusual noise or binding while elevating/lowering
the tabletop.
(B) Monthly inspections:
Check the oil level. Oil should be 1in. to 1
1
/
2
in. below the top of the reservoir/tank with the tabletop fully
lowered. Check for oil leaks. Resolve the issue as described in “Troubleshooting” on p. 13-14. Add oil, if
necessary.
