5.8 Air Hose Connection
Connect air hoses according to the Fig. 5.
Adjust the air pressure regulator to supply 5 kgf/cm
2
of
compressed air to the lift.
Press the DOWN button of the big scissor to see if the
cover of safety ratchet can be pushed away by air
cylinder
6 Lift Adjustment
6.1 Preparation
Add 2# lithium lubricating grease on the moving surface.
Lubricate the interface evenly from left to right.
Add 2# lithium lubricating grease on each joints of the
machine.
Fill up the hydraulic oil tank with the hydraulic oil N32 or
mechanical oil N46.
6.2 Adjustment Procedure
Check if all the connection bolts are tightly fastened.
If there is air in hydraulic system due to new installation,
air bleeding performance is needed. The air in the
master cylinder can be bled after the platform goes up
and down several times. The air in the slave cylinder
can be bled by following steps:1) lift Master Platform
close to the maximal height; 2) close stop valve Z1/Z2
and open stop valve F1/F2; 3) press the UP button to
raise the Slave Platform reaches near the maximal
height, 4)press the DOWN button to lower Slave
Platform to the bottom. All the air in the slave cylinder
can be bled after the operation is repeated three times.
Level the two platforms by charging or discharging oil
and change the stop valve Z1/Z2, F1/F2 back to normal
lifting state.
Press the big scissor UP button to raise the platforms;
release the button to stop the platforms rising. Press
the big scissor DOWN button, the platforms rise a little
automatically to release from the safety ratchet, while
the air cylinders push the safety covers away, and the
big scissor platforms will lower down.
Press the small scissor UP button to raise the small
scissors platforms, release the button to stop the small
platforms rising. Press the small scissor DOWN button
to lower the small scissors.
Adjust the bracket of the limit switch to let the platforms
stop at appropriate height. This will cut off the oil
supply to the cylinder and protect the lift.
For the machine installation on the ground, install the
cover plate after the hoses are connected
The adjustment is completed.
Notice:
Attention should be paid to the position of oil pipes and
hydraulic hose when the platforms move to the minimal
height for the first time. Make sure they don not get stuck
with platforms moving downwards.
When bleeding the air in the slave cylinder, do not lift
Master Platform to the maximal height. Otherwise, the
limit switch is triggered, the power will be cut off and Slave
Platform can not move.
When bleeding the air in the slave cylinder or leveling the
two platforms, lift Slave Platform to 1.5m, and then insert
cardboard under the safety ratchet near the air cylinder to
keep the safety ratchet from becoming effective.
Otherwise the Slave Platform can not be lowered even
when the DOWN button is pushed. Remove the
cardboard after bleeding or leveling.
