Environmentally friendly oil
The environmentally friendly oils recommended for HIAB products are ester based synthetic
hydraulic fluids (synthetic ester).
CAUTION
Vegetable oils do not meet Hiab requirements and must not be used.
After filling the tank
1. Operate each crane function to its end positions.
2. Operate the crane to parked position.
3. Check and top up the oil tank to max level on the tank gauge.
4. Bleed the air from the hydraulic system.
8.6. Replacement of filters
Filter cartridges must be replaced by a Hiab authorised service workshop:
• After the first 50 hours operation
• Then after every 1000 hours operation
• Or at least once a year.
How do you verify if the filter needs a replacement?
The high pressure filter is on the crane base, connected to
the pressure line from the pump. It has an indicator (1) that
turns red when the replacement is needed.
The return oil filter is on the oil tank, and can have a
clogging indicator. This indicator turns red when needed. In
all other cases (if the filter time is expired or without
clogging indicator), you must follow the general
recommendations for its replacement.
There are other filters on your crane (the pressure-reducer filter (1) on remote-controlled cranes,
and the breathing filter (2) on the oil tank). These filters have no indicator and you must follow the
general recommendations for their replacement.
