ANNUALLY (BY SERVICE DEPARTMENT)

The lifting system must be inspected once a year by the service department of Stertil B.V. or by an agency approved by
Stertil B.V. A maintenance contract can be arranged for this annual inspection with the Stertil B.V. Service Department.
If no maintenance contract is entered into, the user himself should make an appointment each year for this inspection and
servicing.
This inspection is recorded on the inspection checklist (see page 43 or the ANSI/ALI ALOIM) and should include the
following checks.
- Daily and Monthly checks.
- Check the gas spring for its proper functioning.
- With the pallet mechanisms in the highest position, lift a vehicle of 8,800 lbs, or more,
approximately 4".
- Then check whether the back of each column rests on the floor.
- Check the general operation of the lifting columns.
- Take the locking device apart, clean its components, place it back and reset it.
- Check the hydraulic oil level.
- Every two years the hydraulic oil must be changed, even if the lifting system has not been used regularly.
- Set the lifting column at its lowest position. Remove the drain plug, from the bottom of the tank,
and drain the oil. Install the drain plug.
- Fill the system (capacity 7 litres) with UNIL HVC S15 filtered at 4 microns max.

Fig. 7.1, Mechanical safety lock adjustment
Set the lifting columns in the lowest position (if necessary, use the
internal switch SET+ and SET- in the control cabinet).
Raise the lifting columns to the first locking device and then lower
them into it. Check whether the adjusting nut of the solenoid has a
clearance of 1/8" - 5/32".
If not, adjust the adjusting nut at the back of the solenoids to 1/8" -
5/32" clearance.
Raise the lifting columns to the highest position and during raising
check clearance.
Lower the lifting columns form their highest position in the safety lock
and check for 1/8" - 5/32" clearance; adjust, if necessary.
Adjust the highest position stop, by means of the set pin of the
potentiometer, so that the locking pawl is placed 1 ½" to 2 ½" past the
last locking profile (see fig. 7.1)
