Safetyregulations
• Never walk under a raised load!
• Before lowering the forks, make certain that no foreign
elements can hinder the free lowering of the forks.e
• The Twin Stacker
isdesignedforuseonanevenandleveloor
• During transport the forks shall be raised as little as possible
• Transport with raised forks should be made over the shortest
possible distances and at low speed
• Check that the chains lift equally. They shall be equally tight when the forks
are loaded
• Chains and chain bolts must not be damaged.
Chains that have become permanently stretched (max. 2% of original length)
must be scrapped.

4.1Avoidoverloads
Maximum capacity in total 1800 kg
Capacity lowest forks: Up to 1800 kg
Capacity upper forks: Up to 800 kg
The maximum load must not be exceeded.
Remember, the pallet truck is designed for evenly
distributed load; - goods on pallets etc.
If the forks are point-loaded on one side, there is a risk of bending.

5.1Fuses-replacement
There are 5 fuses in the electrical circuit, located
behind the plate with this pictogram.
80 Amp fuse for driving motor
80 Amp fuse for lifting motor lowest forks
5 Amp fuse in the control current circuit
20 Amp fuse (built-in charger)
80 Amp fuse for lifting motor upper forks
Replacement:
The old fuse is to be removed and replaced by a new one of the same size.
Do not insert a larger fuse; the fuse acts as a protector for the pump motor.

5.2Wiringconnections
Manyoperationaldisturbancesarecausedbybadconnectionsinthe
electricalcircuit.Makesurethattheconnectionsareinorder.
Check connections regularly for damage at insulating caps or bad connections at
plugs etc.
Verdigris must be removed from cable plugs. Keep all screw/nut connections tight.

Regular inspection and the replacement of worn or defective parts in good time will
prolong the life of the Twin Stacker. “Prevention is better than repair”, therefore
ensure:
- Correct usage
- Regular cleaning
- Periodic safety and service inspection (see the back page)
- Due to safety reasons, the below points have to be checked every 3 months:
- Loose screws and nuts have to be tightened up.
- Breaches, cracks or deformations are not allowed on the load-bearing parts.
- Wearing parts, such as brakes, wheels and bearings, are to be adjusted
or changed continuously
- The lifting chains are to be checked
 6.1Lubricationandhydraulicoil
Under normal operation conditions the Twin Stacker requires no
lubrication.
All ball bearings are sealed and lubricated for life, and moving parts
have self-lubricating bearings or are treated with grease. The hydraulic system is
lledwithhydraulicoilofviscosityclassISOVG15.Anadditiveisaddedtothe
oil. The concentrate reduces friction and wear and protects against corrosion.
Pre-mixed hydraulic oil with additive is available from the dealer. To ensure that
the cylinder pipe is lubricated and thereby protected angainst corrosion, it is
important to lift the forks to top position frequently. The oil is suitable for use in the
temperature range -10° to +50° C. A thinner oil is recommended for temperatures
lower than -10° C (if necessary, contact your dealer).

6.2Adjustmentofsideplay
(Inthemastrollsoftheforkbracket)
1: Loosen nut (B) Screw. (A) is loosened counter-clockwise, until resistance
disappears.
2: Turn the screw clockwise, until resistance appears. The following 1.5 to 2.5 turns
of the screw will be a tightening of the spring (C).
3: When a larger resistance appears, make 0.25 turn counter-clockwise, and the
counter nut (B) will be tightened.
4: Pump the forks to its top position, and when lowering it has to slide to the bottom.
If this is not the case, loosen screw A, make c. 0.5 turn counter-clockwise and
repeat point 4.

6.3Forkadjustment
Two of the rollers on the fork bracket are
mounted on eccentric pins, so that they can be
adjusted. The adjustable rollers are at the top.
1. Loosen screw (pos. 91)
(key width 5 mm).
2. Eccentric pins (pos. 56)
(key width 8 mm) can now be
turned to give the necessary fork
adjustment.
3. Adjustment must be made on both
sides to ensure uniform loading of
the rollers.
6.4Adjustmentofliftingchain
The chains shall be adjusted so that:
• they lift equally
• they are equally tight
• The lifting movement has to stop in the cylinder, before the
mast rolls touch the top stop.
After adjusting, please check:
The nuts (pos. 18) are to be adjusted
(nut M12, key width 19 mm).

When the Twin Stacker is used every day, adjustments and the replacement of worn
parts might be necessary.
Adjustments and minor repair can easily be made on the spot. Major repairs should,
however, be carried through by the dealer who has a well-trained staff and the
necessary special tools.

7.1Remedy
1) Check that the key (1) is turned clockwise and that emergency stop (2) is not
activivated.
2) Charge battery - (see separate instruction manual for battery and charger).
Access to the battery is achieved by removing the battery lid (3).
3) Check switch (4). Check cable connections on switch.
4) Check control current fuse (6).
If the fuse is intact and the truck does not drive, contact the dealer.
5) Check main fuse for driving motor (7).
Check cable connections on drive motor and pump motor.
If no fault can be found and the truck does not drive, contact the dealer.
6) Check the wire connections between the battery cells, and to the battery. In case of
verdigris on the connections, these are to be cleaned.
Checkthatallcableconnectionsarexed.
7) Check the wiring loom on the side of the wheel motor. Check that the brake is
activated when the handle is activated. Check that the brake is adjusted correctly.
If no fault can be found and the truck still brakes, please contact the dealer.
8) Please contact the dealer for the adjustment of the controller parameters.
