Annual maintenance
1.
Turn the main switch off (Position "
OFF“) and
lock with padlock.
2.
Lubricate cross beam cable sheaves with
grease (Consistency classification II).
3.
Check Hydraulic cylinder and Hydraulic hoses
for leaks (visual inspection).
4.
Inspect electrical cables for damage
(visual inspection).
5.
Turn the main switch on again (Position "ON“).
6.
Check that control buttons and switches func-
tion properly.
7.
Replace illegible or missing labels on the post
lift. Re-order from the manufacturer.
8.
Conduct safety inspections
(
Chapter 2.7).
9.
Complete maintenance report and inspection
report from safety inspection (
Annex).
Depending on the level to which it has degraded
1.
Change the hydraulic oil (
Chapter 9.5).
9.4 Approved hydraulic oils
Important information
Only use hydraulic oils in accordance with DIN
51524 for the hydraulic system.
Only use biodegradable oils
(HEES-based on synthetic esters).
Use PTFE seals or foam elastomers if the water
content is high.
ATTENTION
Seals may be destroyed if the in-
correct hydraulic oil is used.
Do not use rapeseed based oils.
The water content of the hydraulic oil must not
exceed 2 %.
Do not mix bio-oils with mineral oils. Mixing
leads to foaming problems and corrosion
damage.
Make sure that the oil is not contaminated by
any other oil or water.
Use a proportionally lower viscosity bio-oil as
a replacement for mineral oil. This improves
the lubrication properties, reduces energy
consumption and generates less heat.
HEES32-bio-oils can, for example, be used as a
replacement for mineral oil HLP46:
PLANTOSYN 3268
BECHEM HYDROSTAR HEES 46 longlife
BP Biohyd 32
Mobil EAL Hydraulic Oil 32 and 46
Oils and grease
Only use consistency classification II oils and
grease.
Water pollutants
Oils and grease are water pollutants in terms
of the Water Management Act (WGH).
Always dispose of these in an environmental-
ly friendly manner in compliance with the ap-
plicable regulations in your country (
Chap-
ter 16. Disposal).
