Inspect the Hydraulic Tank Cap
Venting System
DINGLI requires that this procedure be
performed quarterly or every 250 hours,
whichever comes first. Perform this procedure
more often if dusty conditions exist.
A free-breathing hydraulic tank cap is essential
for good machine performance and service life.
A dirty or clogged cap may cause the machine
to perform poorly. Extremely dirty conditions
may require that the cap be inspected more
often.
1 Open the cover.
2 Remove the breather cap from the
hydraulic tank.
3 Check for proper venting.
⊙ Result: Air passes through the breather
cap.
¤ Result: If air does not pass through the cap,
clean or replace the cap. Proceed to step
4.
Note: When checking for positive tank cap
venting, air should pass freely through the cap.
4 Using a mild solvent, carefully wash the
cap venting system. Dry using low
pressure compressed air. Repeat step 3.
5 Install the breather cap onto the hydraulic
tank.
6 Install the cover.

Inspect the system of wire ropes
Maintaining the system of wire ropes in good
condition can reduce risk effectively after
chains break。
1 Raise the platform approximately 2 m
2 Visually inspect condition of every wire
rope and both ends：
Excessive corrosion or contamination
Untightened wire ropes
Deformed seat plates
Missing or damaged related
components
3 Inspect the chain terminations near the
bottom of each column to confirm that
each seat plate has a lock nut.
