MAINTENANCE
CHARGING THE BATTERY
CONTROL PANEL
1. Daily Check and Maintenance - It is necessary to
check the stacker daily. Special attention should be
paid to the wheels and axles. Material may block
the wheels, forks, mast and chains. They should be
checked for blockage.
2. Hydraulic Oil - Check the oil level every six months.
The hydraulic oil can be ISO VG32, its viscosity
should be 32cSt at 104˚F, total volume is about 4 L.
3. Lubrication - Use motor oil or grease to lubricate all
movable parts.
1. Charge battery when its voltage is less than 10 volts.
2. Please check the battery liquid before charging; if
there is not enough left, add distilled water.
3. The charging location should be ventilated and
away from anything combustible.
4. If the stacker is not in use for a long period of time,
charge it no less than two hours every week.
5. The voltage of the indicator should not be over 15
volts when charging.
6. Do not use the stacker when charging.
1. Emergency Shut-Off - Press when you need to power
off the controls. Turn it clockwise to switch the
power on.
2. Battery Gauge - Indicates the voltage of the battery.
When its voltage is less than 10 volts, do not use the
stacker; you must charge it.
3. Lift/Lower Lever - The control stick controls the
lowering and lifting of the forks.

OPERATING ISSUE CAUSES RECOMMENDATIONS
The forks do not go up to the
maximum height. Not enough hydraulic oil.
Oil has impurities.
Pour in hydraulic oil.
Change the oil.
The motor does not turn on. Emergency Shut-Off is pressed down, the
power is cut off.
The voltage is too low.
Wire connections have come loose.
Connector to DC motor is bad.
Turn it clockwise, switch the power on.
Charge the stacker.
Check and reconnect any loose wires.
Replace with a new one.
The forks do not go down. Piston rod or mast is damaged resulting
from incorrect loading or overloading.
Fork was kept in the up position for a
long time and the piston rod rusted or is
jammed.
Release valve of the pump is not opened.
Replace with a new one.
Lubricate piston rod. Always keep the fork
in the lowest position when not in use.
Check it. If damaged, replace with a new
one.
Leaks. Seals are worn or damaged.
Piston parts are cracked or worn too small.
Replace with a new one.
Replace with a new one.
Forks descend without engaging
the lower lever. Impurities in the oil caused release valve
