8.2.1
If the pla�orm �lts fore-and-a� when li�ing, first check if vehicle is parked correctly; second check the
perpendicularity of post. Replace the rubber sliders if the pla�orm s�ll �lts a�er the above-men�oned works.
8.2.2
If the pla�orm �lts right-and-le� when descending, first check if the mechanical an�-falling locks are
unlocked correctly, make sure the wiring and related electromagnet works well if the locking block is locked.
8.2.3
If the pla�orm �lts fore-and-a� when descending, first check if vehicle is parked correctly; second check the
perpendicularity of post, if the pla�orm s�ll �lts a�er the above-men�oned works please replace the rubber
sliders.
8.2.4
Adjust the thro�le valve on the power unit, if the li�ing/descending speed is too fast or too slow.
8.2.5
Check if the emergency stop bu�on is open and air switch is closed, if pla�orms don’t move up when keep
turning UP.
8.2.6
Check if the solenoid valve is open, if the pla�orms only move up but not descends or don’t move at all when
keep turning DOWN.
8.2.7
Check if the electromagnet is working to unlock the mechanical locks, if pla�orms descend and stop on the
locking hole when keep turning DOWN.
8.2.8
Air in cylinder is to be eliminated through vent valve of the cylinder, if pla�orms jounce in the movement.

Maintenance and servicing of power pack
8.3.1
Inspec�on of power pack
■
8.3.1.1
Regular inspec�on
◇
8.3.1.1.1 Operate the parking li� for a c
ycle
to make sure it can be normally pressurized and
depressurized if needed.
◇
8.3.1.1.2 Any abnormal noise during opera�on should be checked.
◇
8.3.1.1.3 Working temperature of motor should be checked regularly to make sure it’s within normal
range (from -25
℃
to +60
℃
) .
◇
8.3.1.1.4 Check the possible leakage and abrasion at every oil hose connec�on. Fasten or replace the
sealing at oil hose connec�on and fi�ng if any leakage or abrasion found.
■
8.3.1.2
Monthly inspec�on
◇
8.3.1.2.1 Check and replace the oil hose if any crack
s
, abrasion or leakage
is
found.
◇
8.3.1.2.2 Check and replace the power line if any crack, abrasion or cut is found on insula�ng layer of
power line.
◇
8.3.1.2.3 Check
c
leanness
of
inlet filter and inside of oil tank. Clean or replace filter if
needed
.
◇
8.3.1.2.4 Check the oil level when the pla�orm is at lowest posi�on. Hydraulic oil is to be replenished if
lower than lowest oil level.
8.3.2
Maintenance of power pack
■
8.3.2.1
Make sure the power supply is cut off and pla�orm of parking li� is lowered down to ground before
maintenance.
■
8.3.2.2
Power line, oil hose or other component is to be replaced with the same specifica�ons.
■
8.3.2.3
The whole hydraulic system is to be depressurized completely before opened.
Note:
the life�me of
the
hydraulic system may be affected by environment, human factor or life�me of
hydraulic components. Proper and regular maintenance could lower probability of malfunc�on.
8.2
Servicing
8.1.13
An electromagnet with noise shall be replaced ASAP.
8.1.14
Any broken safeguards, warning signs, safety informa�on, markings and ligh�ng shall be replaced in �me.
