See E-1, Test or Replace the Hydraulic Oil.
Table C Procedures C-1 Replace
hydraulic hose
Maintain good hydraulic hose to normal and security
work machine is very important.If not found in using the
old,broken or leakage of hose may cause mot safe
operation conditions.
Clean the execution of the
program in any process of the hydraulic oil spill.
In the case that close machine
execution of the situation.
Table D Procedures D-1 Check the
Wear Pads and sliders
Maintaining the wear pads in good condition is
essential to safe machine operation. Don’t properly use
the slider gaskets or continuous use of old slider may
cause components and not safe operation of the case.
1 Lift up the platform,ensure the safety.
2 Measure each wear pad.
Specifications of slider:the thickness less than 10mm
3 Replace any wear pad if it is less than specification.
If a wear pad is not less than specification, shim as
necessary to obtain zero clearance.
4. Extending the work platform over the entire range of
motion and check the key parts that may lead to the
extended platform jammed.
Table E Procedures
E-1 Test or
Replace the Hydraulic Oil
Replacement or testing of the hydraulic oil is
essential for good machine performance and service
life. Dirty oil and suction strainers may cause the
machine to perform poorly and continued use may
cause component damage. Extremely dirty
conditions may require oil changes to be performed
more frequently.
Perform this procedure with the
boom in the stowed position.When remove the hose
and pipe fittings, the O-rings on it must be replaced. 1
Open the ground control box at the bottom 2 Remove
the cover of hydraulic oil-tank and drain hydraulic oil
into suitable container.
3 Disconnect and plug the suction tube. 4 Disconnect
and plug the oil-return tube beside the oil-return filter.
5 Disassemble the hydraulic oil-tank and oil-return
filter, then fasten the bolts
6 Remove the hydraulic oil-tank from the machine.
7 Remove the oil-return filter
8 Replace filter screen of oil-return filter
9 Clean the inside of the tank using a mild Solvent.
10 Install oil-return filter
11 Install the hydraulic oil-tank onto the machine 12
Install the hydraulic oil-tank and oil-return filter and
then fasten bolts
