Operating Instructions
GB
Vibrations There are no signicant vibrations as the machine is electrically
powered.
Disposal When disposing of the truck, the battery should be recycled. The
remainder of the truck should be disposed of by a scrap dealer.
WARNING
Moving parts
Take care not to allow people or objects to get
crushed when tipping the truck bed.
WARNING
Safety guards
When the truck is in operation, all safety guards must
be secured.
WARNING
Maintenance
Before starting maintenance work, bring the truck to a
complete standstill to ensure that there is no danger
of personal injury due to moving parts.
The truck speed should be adapted to the conditions, i.e. reduce
speed at corners and in narrow passages. There is a risk that the truck
may overturn when travelling on an incline. Never drive on an incline
of more than 20° across the direction of travel. When travelling fully
loaded down a steep hill, the truck must travel at very slow speed
(tortoise mode). If you drive too fast down a hill, the truck may (worst
case) run out of control. Make sure the brakes are in good working
order at all times.
Max. incline in direction of travel:
• about 40% over a distance of 0.5 metres
• about 20% over a distance of 1-2 metres
• about 15% over a distance of 3-5 metres
If the incline is steeper and the truck fully loaded, there is a risk that the
truck will stall on the incline and (worst case) may roll backwards.

WARNING
Risk of personal injury/death
Flames and sparks are not permitted in the vicinity
of the battery. Power down the mains supply contact
before releasing the charger clamp.
WARNING
Risk of personal injury/death
Some internal parts of the charger carry live current
and represent a risk of personal injury. The charger
frame must therefore only be opened by specially
qualied personnel.
COMMENT
Important information
The charger is not suitable for domestic use or for
use in ofces or similar electrical environments.
The battery charger is an automatic, microprocessor controlled
charging unit, which is intended specically to charge open lead-acid
batteries. Charging specications according to DIN 41774.
General comment
The charger must be located in a dry, well-ventilated space.
• The charger should be connected to the mains power supply It must be earthed and fused. Connect in accordance with the
specications on the charger type plate.

• Connect the battery. Switch on the mains supply. The POWER ON
diode is lit when the unit is charging.
• When the charging level reaches 2.43 V per cell, the charger
reduces charging to a pre-programmed voltage charge level and the
next diode lamp lights up. The charger charges at constant voltage
for about 60% of the main charging period.
• Then the pulsed maintenance charging phase starts. A green diode
lights up.
The battery is now fully charged.
Recharging
• If the battery does not reach 2,43 V per cell after 10 hours of
recharging, switch off the charger. The lower red diode lamp lights
up. The red diode lamp indicates that there is an error or that
charger safety is compromised.
• If the total charging time exceeds 16 hours, the charger switches
to maintenance charging.
• In the event of a power cut, the charging timer is interrupted. The
timer restarts when the power is resumed. The charger's charging
diode lamp is extinguished during a power cut.

COMMENT: NEVER add acid to the battery, only battery uid.
Do not store battery uid in a metal container. To top up, use equipment
made of plastic or other non-conductive material, which can also
withstand contact with water and acid.
If the acid level is too high, there is a risk
that it will spill over during charging, which
may damage the battery or underlay.
If the battery has toppled or if acid has
leaked from it, contact GMR maskiner a/s.
Always keep the battery clean and avoid
acid spills. If metal parts are tainted with
acid, clean them. To protect them from
further adverse effects, lubricate with
acid-free Vaseline.
Boards and separators must always be
covered by the acid. Never top up with
more battery uid than indicated on the

The battery lling system (BFS) caps work best when water pressure is
0.3-2.0 bar, which corresponds to water column pressure when pouring
from a height of 3-20 metres.
If the pressure is too low, the caps may fail to close at the correct level in
the cells and continue to ll. The battery will then overow, which affects
electrolyte density and may damage the battery box and underlay.
The canister must be placed at least three metres above the cell caps,
preferably higher.

Lithium batteries
Page 18
Operating Instructions
GB
The lithium battery pack contains a number of individual LFP cells. The
pack has a nominal voltage of about 3.3 V per cell. This is the safest
type of lithium battery on the market.
LFP batteries have a at discharge curve, i.e. the voltage remains at
about 3.2 V until the battery is about 80% discharged, after which the
voltage diminishes sharply. To minimise the risk of damage and prolong
the lifetime of the batteries, we recommend that they are never more
than 80% discharged.
LFP battery discharge curve at different temperatures
Voltage (V)
Discharged capacity (%)
LFP batteries have a longer lifetime than conventional lead-acid
batteries. They can withstand more than 3,000 70% depth of discharge
(DOD) cycles. The voltage of LFP batteries must not fall under 2.5 V
per cell. If voltage falls below this level, the cells may be irreparably
damaged.

Battery management
system
BMS = Battery Management
System
The lithium-ion battery pack is tted with BMS, a system which monitors
the voltage in each individual battery cell. A combined battery sensor/
balancing unit is tted to the top of each cell.
The PCB is tted directly onto the cell's + and - terminals and has two
functions:
1. The board constantly monitors cell voltage so that it remains within
the permitted range (2.6-4 V). If voltage is within the permitted
range, a green diode lamp lights up, The unit's output signals to the
main monitoring system that everything is in good working order.
2. The unit also helps to balance the cells while the battery pack is
recharging. When the charge voltage exceeds 3.6 V, the unit starts
to deduct balancing energy from + to - , increasing to 1 ampere
when maximum voltage (4.0 CV) is achieved. When the PCB is
balancing (deducting power), a red diode lamp lights up (at the same
time as the green one). The red diode lamp on the sensors does not
signal that there is an error.
Stama trucks with reset
button (until 2014)
The PCB outputs are daisy chained and monitored by a
micro-controller-based (MCU) monitoring system.
GMR maskiner a/s
STAMA Micro, Parker, Mini, Multi, Evo, Maxi EL
Lithium batteries
Page 20
Operating Instructions
GB
There are two diode lamps on the MCU:
The green diode lamp indicates that
there is a 12 V supply to the PCB.
As long as the monitoring circuit is intact, the MCU ensures that a small
12 V relay remains connected. The 12 V relay supplies all remaining
units which take energy from the battery, e.g. the key switches, main
and pump relays.
The MCU monitors the cell circuit. If the circuit is broken, the red diode
lamp ashes. After 10 seconds, the relay is disconnected and the red
diode lamp lights up.
The MCU is disconnected if the main switch is disconnected.
The red diode lamp indicates that the
monitoring circuit is broken, i.e. that
there is a problem with at least one of
the cells.
MCU diode lamps
A break in the MCU circuit can be caused by a cell with excessively
low voltage. If this is the case, recharge the battery. Press reset button
briey.
Resetting the MCU
Insufcient cell voltage
Open main switch If there is a break in the MCU circuit caused by the main switch having
been opened, just press the reset button briey. The truck does not
need recharging.
If the MCU is triggered during charging, the charging voltage may
be too high or the battery imbalanced. Try pressing the reset button
repeatedly.
If one of the red cell sensor diode lamps lights up much earlier than the
others, the voltage in this cell is too high. The cell may be damaged.
If the cell is damaged, contact GMR maskiner a/s.
Excessive charging
voltage or imbalanced
battery
Stama trucks with no reset
button (after 2014)
Stama trucks which do not have a reset button are tted with a simple
BMS, in which the MCU is replaced by a simple BMS relay, which
requires no resetting. If all the battery sensors light up green, the
BMS relay is activated and the machine can be started. If just one of
the sensors does not light up green, the relay is not activated and the
batteries will not be excessively discharged.

Lithium batteries
Page 21
Operating Instructions
GB
The battery charger charges all the batteries serially and
simultaneously to a charge voltage of 3.65 V per cell. The charger
charges constantly until the desired voltage level is achieved. Then the
charge voltage is reduced until full starting voltage is achieved. The
starting voltage is maintained until the charger is switched off.
Before the charge voltage is reached, all the cell sensors' red diode
lamps should light up.
The battery pack is fully charged in seven hours.
Lithium-ion batteries should not be subjected to charge voltage over
a prolonged period of time because constant high charge voltage
reduces battery capacity. Disconnect the charger when the batteries
are fully charged.
During storage, the battery discharges 3% a month and, to avoid
reaching full depth of discharge, it must therefore be recharged at least
every six months. Lithium batteries are maintenance-free.
Lithium-ion battery charger
Lithium batteries can withstand frost, and can be used down to minus
20 °C, though with reduced capacity.
Cold
• If they are corroded, clean cell terminals with a dry brush.
• Keep electrical connections dry at all times.
If you have a question or need more information material,
contact GMR maskiner a/s.
COMMENT
Important information
To avoid irreparable damage, NEVER allow lithium
batteries to discharge completely.
CAUTION
Damage to machinery or attachments
Do not open the cells as this can ultimately
(worst case) cause irreparable damage.
CAUTION
Damage to machinery or attachments
Lithium batteries must be at least +5 ˚C before
they may be recharged. If colder batteries are
charged they can be permanently damaged.
