The discharge status is indicated by ten red LED segments.
Battery discharge indicator
Only when the battery is properly charged, the most right LED lit. As the battery’s state-of-charge decreases, successive
LEDs light up, only one on at a time.
The 2
nd
from left LED flashes, indicating “energy reserve” (70% depth of discharge).
The 2 most left LEDs alternately flash, indicating “empty” (80% depth of discharge).
BATTERY CHARGING
Battery charging must comply with any instruction manuals provided by the battery and charger
suppliers.
Before charging, make sure the Emergency Stop switch are in the off position. Charge the battery in a dry
and air-circulated environment and keep away from fire sources. The battery should be charged regularly (once per month at a
minimum).
When the battery power is low, discontinue use and charge the battery immediately.
AUTOMATIC CHARGER
A fully automatic smart charger is included with the stacker. The charger indicator lights in red when the battery is
charging. The charger will automatically adjust the current flow according to residual capacity of the battery, which
ensures an optimum charge. When complete, the charger indicator lights green and the charger automatically stops. A full
charging course generally lasts 5-7 hours.
IMPORTANT:
Before charging, make sure no metal objects are on the battery. Check for any obvious faults on all cables
and plugs. Safety instructions, including common rules and battery charging preparation procedures, should be strictly
observed. During charging, cock caps for each cell should be opened to maintain air circulation conditions.
Maintenance
SAFETY OPERATION AND ENVIRONMENTAL PROTECTION
The instructions in this section should be performed based on the time intervals specified in the Maintenance List.
No part of the stacker, especially safety devices, may be changed without the manufacturer’s written
permission. All spare parts from the manufacturer are qualified by Quality Assurance Authorities. To ensure safe and
reliable stacker operation, only spare parts from the manufacturer should be used. Replaced parts, including oils and
fuels, must be disposed according to environmental protection regulations.
MAINTENANCE SAFETY RULES
MAINTENANCE STAFF
Repair and maintenance should only be performed by qualified professionals who have been trained by the manufacturer.
LIFTING THE STACKER
Hoisting equipment used to lift the stacker should be safe and reliable. When the stacker is lifted, necessary precautions
should be taken to avoid slipping or overturning of the stacker (a wedge block or wood block can be applied). The stacker
should be lifted only when the forks are fixed and adequately strong connecting cables are applied.
CLEANING
Using flammable fluids to clean the stacker is strictly prohibited. Before cleaning, safety measures must be taken to avoid
sparking (e.g. caused by short circuit). Battery work should only be performed after cutting off the power. Electric elements
and electronic assemblies should only be cleaned using compressed air or a nonconductive, anti-static brush.
If the stacker is cleaned with a high pressure washer, all electric elements and electronic assemblies
should be covered to avoid a functional fault. Cleaning with a steam nozzle is prohibited.
ELECTRICAL SYSTEM
Work on the stacker’s electrical system should only be performed by trained professionals. Protective measures should be
taken to avoid electric shock. Before beginning work, separate the battery socket to cut off power to the stacker.
