Maintenance
4.1 Daily visual inspections
Check functioning and completeness of the operating and safety devices.
Check that all warning and instruction labels are legible. Check for damage and
completeness of pins and check that pins are securely tightened. Check cylinders for
damage to/tightness of hoses, screw connections, and valves. Check warning lights for
damage and functioning.
Check functioning of battery master switch (optional equipment).
4.2 Annual inspection
After commissioning, the liftgate must be inspected at least once a year by trained
personnel. The results of this inspection must be entered in the inspection record book.
4.3 Care, maintenance, testing, and repair
Before starting maintenance, secure the liftgate against unexpected movement. Check
that all screw connections are tight.
Check that cables and hoses are able to move freely. Correct shearing and chafing
points on cables and hoses. Immediately replace damaged hydraulic hoses with new
hoses of the same quality and note the replacement in the inspection record book.
During cleaning, make sure that no moisture penetrates the power pack, control panel, or
handheld control. Do not clean the bearing areas with high-pressure or steam jets
because this may allow dirt and moisture to penetrate the bearing.
Check the hydraulic unit for leaks. With the liftgate lowered, check the oil level in the
unit’s reservoir (dipstick on the oil filler neck cover). If necessary, top up with hydraulic
fluid of class HLPD 22 (temperature range 5°F to +122°F).
The maximum oil level has been reached when the dipstick dips 3/8” into the oil.
Carry out an annual oil change and clean the suction filter. Carry out the oil change
before any period of frost, in order to prevent the hydraulic unit from freezing.
