1.2 Safety precautions and warnings
Please read this manual before you put the machine into operation for the first time, and observe the safety
instructions at all times. The most important instructions are marked with a symbol.
Any person in charge of the commencement of operation, the operation itself or the maintenance of the machine is
urged to carefully read and observe the following instructions.
1.2.1 Safety precautions
The following safety instructions apply to all types of WIFO Lifting masts. No distinction is made with regard to the
type of lifting vehicle used.
Operate the mast only from the driver's seat of the tractor. Ensure that there is adequate visibility of the
work activities from this position.
At all times make sure that everybody is out of range of the working range from the lifting mast and never
stand under the box/pallet or lifting mast. Please be aware of falling products.
Never transport people on/with the lifting mast.
This symbol is used for all important actions that should not be carried out under any circumstances.
Carefully observe these prohibitions.
This symbol is used for all important safety instructions throughout this manual. Carefully observe the
instructions and be very cautious.

You can only turn off the tractor when the lifting mast is in the lowest position. Ensure that the combination
cannot make any sudden movements, if the combination is not used. If the mast is removed and set aside, it
should be the supported by the support legs. Place the machine on a firm, flat surface.
Make sure the hydraulic hoses and any power cables do not get jammed when operating the lifting mast.
Make sure that when lifting or lowering the mast it doesn’t hit the tractor.
Make sure that the operating lever for operating the cylinder (s) may not be confused with other control
levers to prevent inadvertent tilting.
For lifting operations only use proper lifting pallets and boxes.
Place the forks as wide as possible in order to get the greatest possible stability of the load.
Load the pallet or box so that the load cannot fall off unexpectedly. Distribute the load as evenly as
possible on both forks. Keep the center of gravity of the load as close to the fork carriage.
Transport objects with the load as low as possible to keep the tractor as stable as possible. Ensure that
there is sufficient pressure on all 4 wheels of the tractor, also pay attention to the moving of the center of
gravity when lifting, lowering and other activities and especially pay attention to the rough terrain and
slopes when working. If desired, use counterweights and / or twin wheel. Or set the track width of the
tractor wider.

2.3.2 Commissioning of a HM/HMD lifting mast
1. Make sure that the drawbars of the three-point hitch of the tractor are at the same height. Connect the
lifting mast to the category II three-point hitch of the tractor. Use proper spring clips. Adjust the toplink in
such a way that the forks of the fork-lift mast are in a horizontal position. (See using a tilt cylinder / hydraulic
top link "accessories") The lateral movement of the mast in the linkage should be minimal. This is set with
the stabilizers of the linkage.
2. In case of a fork lift mast with a lifting height of 2 meters or more, it is a requirement by law to provide the
tractor-linkage with a blocking device in order to prevent tipping over of the fork lift mast.
3. Connect the hydraulic hoses. Make sure the hydraulic hoses are clean before connecting them to the rapid-
action couplings, to prevent any debris from entering the hydraulics of the machine.
4. Subsequently check that the hydraulic hoses can move freely and check that the system is not leaking oil.
5. Remove the support legs.
De WIFO lifting mast is now ready to be used.

15
2.4 Accessories
2.4.1 Sideshift
Purpose of use:
The lifting mast can be equipped with a sideshift to move the load from side to side. The tractor must be
equipped with an extra double action hydraulic installation or operation must be done via an extra valve
block. See also chapter 2.4.3.
Commissioning:
Tilt the fork lift mast and place the lift with the moving frame onto a level and firm surface in such a way
that the lower beam is within easy reach. Use suitable lifting equipment (minimum lifting capacity 500kg).
Loosen the cylinder bolt(s) and provide sufficient support for the cylinder. Loosen the bolts and remove the
lower beam. Fasten the ground plate for the sideshift (no. 40) with the bolts. Take care that the sideshift
cylinder ends up at the tractor side of the fork lift mast. Fasten the liftening cylinder(s) again with the
cylinder bolts and tighten them securely.
Place the lifting mast back on the tractor. Connect the hydraulic hoses. It is imperative here that the
shortcuts are clean so that no dirt enters the hydraulic system of the machine.
Manual:
Use the sideshift to keep the load as much as possible in the centre of the tractor. Take care that the
hydraulic hoses cannot become entangled. Take care that the operating handles for shifting sidewards
cannot become mutually entangled with other operating handles in order to prevent unintentional
operating.
Figure 2.4.1-Exploded assembly drawing for the sideshift

16
2.4.2 Hydraulic connections on the cart
Purpose of use:
The fork lift mast can be equipped with a hydraulic connection to the fork carriage to allow the connection of
ancillary hydraulic cylinders or hydraulic motors to the fork carriage. The tractor must be equipped with an
extra double action hydraulic installation or operation must be done via an extra valve block. See also
chapter 2.4.3.
Commissioning:
Make sure the mast and the fork carriage is in the lowest position. Loosen the chain (s) by slightly turning
the nuts on the chain tightener. Remove the bolt(s) in the hose roll and replace this (these) by M16x120
bolt(s) which fasten the hose roll and the bushes for the hose roll at the same time. Tighten securely. Place
the hoses on the roll. Mount the hydraulic connectors to the mounting plate on the fork carriage. Secure the
hoses to the forak carriage with hose clamps. Don’t tighten the hoses too tight. Connect the hoses to a
double acting hydraulic connection. It is imperative here that the shortcuts are clean so that no dirt enters
the hydraulic system of the machine.
Manual:
Take care that the hydraulic hoses cannot become entangled. Take care that the operating handles cannot
become mutually entangled with other operating handles in order to prevent unintentional operating.

2.4.3 Valve block
P1/P2: On-/Of drain
T/O: Lifting cylinder
C1/C2: Tilting cylinder
C3/C4: Sideshift/hydr. connection
Purpose of use:
The lifting mast can be equipped with an additional valve block so that the additional hydraulic function can
be centrally controlled and only two hydraulic connections have to be connected or disconnected in
attaching or taking off the fork lift mast. Connect lever (No. 69) on a double working valve of the tractor.
Commissioning:
Place the valve support (No. 65) in the tube provided on the outer frame. Connect the hydraulic hoses for
the various functions to the valves in pairs. Tighten the connections and swivels securely. Connect the inlet
and outlet hoses of valve block. Connect the inlet and outlet hoses of the valve block, taking care to use the
left hose (as seen in the driving direction) of the valve block as the pressure duct. It is imperative here that
the shortcuts are clean so that no dirt enters the hydraulic system of the machine.
When using a electro-hydraulic valve the switch should be mounted in such a position that the tractor driver
can access it easily from its operating position and make sure that the handle can't be confused with any
other controls to prevent unintentional operating.
Take care of the correct voltage of the tractor. The coil (no. 68) is only suitable for 12 volt. Connect a 2-wire
cable according to the diagram, consider adding an indicator light, fuse and / or socket on the circuit. Note: if
the valve block is placed in the tractor all hydraulic hoses factory performed are one meter longer than
specified in the parts list.
Manual:
Take care that the hydraulic hoses cannot become entangled. Take care that the operating handles cannot
become mutually entangled with other operating handles in order to prevent unintentional operating.

2.4.4 Tilting cylinder/hydraulic top link
Use of purpose:
The fork lift mast can be equipped with a tilting cylinder/hydraulic top link to facilitate leveling of the forks.
The tractor must be equipped with an extra double action hydraulic installation or operation must be done
via an extra valve block. See also chapter 2.4.3.
Commissioning:
Attach the tilting cylinder/hydraulic top link by means of the top pin and the securing clip 9x11. Connect the
hydraulic hoses. It is imperative here that the shortcuts are clean so that no dirt enters the hydraulic system
of the machine.
Manual:
Keep the load near the tractor during transportation, with the aid of the tilting cylinder/hydraulic top link.
When loading and unloading the forks keep them as flat as possible using the tilt cylinder/hydraulic top link.
Take care that while operating the fork lift mast the fork lift mast cannot touch the tractor. Take care that
the hydraulic hoses cannot become entangled. Take care that the operating handles for controlling the tilt
cylinder/hydraulic top link cannot become mutually entangled with other operating handles in order to
prevent unintentional operating.
