NOTICE
Make sure the vehicle battery power is disconnected while installing the lift. Connect the battery power to the lift only when the
installation is completed, or as required in the installation instructions.
Except for the support channels and bracing of the side steps, which are usually welded to the cross members of the auxiliary
chassis, DHOLLANDIA lifts are designed as a bolt-on system, and don’t require any welding. See Appendix 2 for
prescribed torque values.
Welding should be done by qualified personnel only, and only to the extent allowed by the vehicle manufacturer. Ensure that
the positive and ground cables are disconnected from the batteries, and that all vehicle electrical and electronic equipment is
fully isolated before welding.
ALWAYS keep the ground clamp as close as possible to the weld location.
CAUTION
Welding on galvanized parts can produce hazardous fumes. To avoid intoxication:
ALWAYS wear a suitable respirator.
ALWAYS provide good ventilation.
ALWAYS grind off the galvanization from the areas to weld.
Most lifts are equipped with thermoplastic hoses, that can be damaged by hot metal chips, welding sparks and slag.
Damage to a hose can lead to sudden loss of hydraulic pressure and an accidental drop of the platform.
The penetration of welding sparks and slag can also cause a flame flash.
Both types of incidents can put the welder or installer and any bystanders at great risk of personal injury or death. To avoid
these risks:
ALWAYS protect and cover thermoplastic hoses with a welding blanket, prior to grinding, drilling and welding.
ALWAYS inspect the hydraulic hoses at the end of the installation process. Make sure all hoses are undamaged,
replace them if required.
Welding can cause severe damage to the electronic components of the vehicle and lift. To prevent damage:
ALWAYS follow the instructions and precautions of the vehicle manufacturer.
DO NOT weld if this is not authorized by the vehicle manufacturer.
ALWAYS disconnect the battery and ground terminals from the battery.
ALWAYS connect the ground directly to the component being welded, as close to the weld as possible.
Welding should be done by skilled and qualified tradesmen only.

of a slow loss of hydraulic pressure.
See also terminology description above for differences between DH-P2 / PH2*
and DH-P1 / PH1*.
8
Main battery disconnect switch: switches the main power from the vehicle
battery to the lift on / off.
It will stop the lift in case of emergency involving hazard to the operator
or wheelchair occupant.
It will stop the lift and reduce the risk of a power pack burn-out if the
starter solenoid is stuck and the motor runs continuously (control button
or contact damaged, starter solenoid short circuited by low voltage).
9
Main battery fuse: a main fuse 100 –150A is supplied by the vehicle
manufacturer or by DHOLLANDIA. It protects the main battery cable from the
batteries to the power pack of the lift against short circuits and amperage peaks.

15A fuse: fuse is used to protect the control unit, associated wires and the printed
circuit against short circuits and amperage peaks.
11
Emergency descent button: manual back-up button to open (= DEPLOY) and
lower (= DOWN) the platform in case of an electrical power failure.
12
Hydraulic hand pump: manual back-up pump to lift the platform in case of an
electrical power failure (= UP).
13
Pressure relief valve: safety device integrated in the power pack, enabling the manufacturer and the installer of the lift to limit
the real lift capacity to the maximum rated capacity of the lift sold, and protect it against overload while lifting (= UP).
14
Pressure compensated flow valves: flow valves are integrated in the hydraulic circuits to ensure the platform lowers at a safe
speed, both empty and when fully loaded.
15
Decals: the lifts are supplied with a number of operation decals, load diagrams and safety decals. Some of these decals are
premounted by DHOLLANDIA on the lift. Some of these decals are supplied loose and shall be affixed by the installer near to the
lift at a location clearly visible to the operator.
The decals must be kept clean and legible at all times, and replaced whenever required.

7GETTING STARTED
Many vehicle manufacturers issue important instructions on various aspects of the lift installation, specific to the brand and type
of chassis. Examples:
welding instructions or the prohibition to weld
instructions on chassis drilling and bolt-on connections to the chassis
recommendations on the use of hydraulic stabilizing legs
guidelines on fuses, electrical interfaces, and the connection of battery and ground cables, etc.
NOTICE
ALWAYS verify and ensure compatibility between the lift and the vehicle.
ALWAYS ensure compliance with the fitting and body building instructions issued by the vehicle manufacturer.
Make sure planned modifications to the vehicle chassis and body will not adversely affect the strength and integrity of the vehicle.
If the instructions of vehicle manufacturer conflict with the installation instructions issued by DHOLLANDIA (e.g. on fuse ratings,
etc.), contact your national DHOLLANDIA distributor for further advice. See contact info on page 4
Verify if the installation kit is complete and that all parts needed to install the lift, are present.
Compare the voltage of the batteries with the voltage of the hydraulic power pack of the lift.
Compare the actual vehicle dimensions with the maximum installation parameters indicated in the technical documentation. If
the actual dimensions go outside of the maximum installation parameters, DON’T continue and contact your national
DHOLLANDIA distributor for further advice.
Verify and make sure that the vehicle chassis and body are strong enough to support the forces induced by the lift at its
maximum rated capacity. Refer to the instructions of the vehicle manufacturer for calculation and construction guidelines.
Execute the required stability and weight distribution calculations.
Make sure that the body is accurately fitted to the vehicle chassis.
Remove all objects that impede the installation of the lift (bumper bar, spare wheel carrier, pallet racks, tool boxes, etc.). If
necessary, consult with the vehicle manufacturer for replacement solutions (e.g. special spare wheel carriers, exhaust pipe
modifications, etc.).
Finish the lift in accordance with the road legislation of the country where the vehicle will be registered.
When connecting hydraulic fittings, make sure that the connections are clean, and that you don’t contaminate the hydraulic oil.
Grease all bearings and pins before putting the lift into service. Preferably, put grease in the bearings before mounting the
corresponding articulation pin.
After installation, work through the checklist of the Pre-Delivery Inspection (PDI). Make sure the final inspection is signed off
by an inspector who is not part of the installation team.
Do not pressurize any lift functions (OPEN / CLOSE) before the installation is fully finished.
During installation and testing, verify and make sure that the lift and its moving parts don’t interfere with any of the vehicle
systems (e.g. the suspension, braking system, hydraulic and electrical circuits, etc.), or cause damage to them.
