§7.8 - Importance of preventative maintenance
NOTICE
•
Competent and regular preventative maintenance is essential to the operational reliability of the liftgate as well as the safety of
the operator and all bystanders.
•
All maintenance and repair work must be performed by authorized DHOLLANDIA service agents, and using original
DHOLLANDIA replacement parts only.
•
Please consult the separate MAINTENANCE AND REPAIR MANUAL for specific instructions regarding periodic maintenance.
Make sure the platform surface is clean and can be accessed safely. Remove any snow, mud, dirt, debris, or slippery liquids.
Make sure you wear safety-toe shoes with a good non-slip sole.
Check the cylinder beam and optional tilt cylinders, their lock valves and fittings for visible oil leaks. Follow the hydraulic pipes
and fittings to the pump unit. Make sure all wires and hydraulic pipes are undamaged, not pinched or chafed anywhere, and
adequately secured with cable ties. Check for visible oil leaks.
Perform all movements with an unloaded platform several times with all available control units. Use the operation manual for
guidance.
Make sure all movements occur smoothly and quietly, without jerking motion or unusual noises. During LIFT and CLOSE
functions, only the sound of the electric motor in the pump unit should be audible.
Remember: if any part of the pre-trip inspection reveals a need for service or repair
→
DO NOT use the liftgate until it has been serviced or repaired by a qualified service technician.
→
Switch OFF power at the main battery disconnect switch or cabin switch
[see §9.5 on page 40].
→
Attach the 'WARNING. LIFTGATE OUT OF SERVICE. DO NOT ATTEMPT TO OPERATE' sign provided with the
liftgate in a clearly visible location
[see §10.2 on page 56].
•
If a liftgate cannot be repaired immediately in case of breakdown, it must be put out of operation and secured against
unauthorized use.
•
A liftgate put into its travel position with the help of external devices (forklift, gantry crane,…), is not supported by its hydraulic cylinders.
After releasing the mechanical platform lock, the platform and lifting mechanism will drop in free fall, without any possibility to stop the
fall by means of the regular controls.
Impact by a falling platform will result in serious bodily injury or death. To reduce the risk of injury:
→
Close the platform lock (if available), and apply additional means to immobilize the platform [see
Note below].
→
Attach the 'WARNING. LIFTGATE OUT OF SERVICE. DO NOT ATTEMPT TO OPERATE' sign
provided with the liftgate in a clearly visible location.
→
If you cannot locate this laminated sign, use an alternate method to signal the hazard clearly.
•
Note: examples of additional means are additional securing of the platform lock (if available), or securing the platform by means of
ratchet straps, hoists, etc.
•
To re-open the liftgate, use again an external device (forklift, gantry crane,…) for additional support. Or repair the breakdown
first, bring the hydraulic system under pressure, and release the platform locks after satisfactory testing of the hydraulic integrity.
Follow the MAINTENANCE MANUAL for all maintenance and repair works.
