BATTERY MAINTENANCE
Electrical energy for the motor is supplied by four 6 volt
batteries wired in series to give a 24 volts DC supply.
Proper care and maintenance of the batteries and motor
will ensure maximum performance from the work
platform.
Hazard of explosive gas mixture. Keep
sparks, flames and smoking materials away from
batteries
Always wear safety glasses when working
with batteries.
Battery fluid is highly corrosive. Rinse away
any spilled fluid thoroughly with clean water.
BATTERY INSPECTION AND
CLEANING
Check battery fluid level daily, especially if work platform
is being used in a warm, dry climate. If required, add
distilled water; use of tap water with a high mineral content
will shorten battery life.
If battery water level is not maintained, batteries will
not fully charge, creating a low discharge rate which
will damage Motor/Pump unit and void warranty.
Batteries should be inspected periodically for signs of
cracks in the cases, electrolyte leakage and
corrosion of the terminals. Inspect cables for worn spots or
breaks in the insulation and for broken cable terminals.
Clean batteries that show signs of corrosion at the
terminals or onto which electrolyte has overflowed during
charging. Use a baking soda solution to clean the batteries,
taking care not to get the solution inside the cells. Rinse
thoroughly with clean, warm water. Clean battery and
cable contact surfaces to a bright metal finish whenever a
cable is removed.
WARNING
CAUTION
Basic Rule for maximum duty cycle of deep cycle
traction batteries:
l
Use the machine until it shows signs of weak / slow
performance.
l
Allow the charger to charge the batteries until it
automatically shuts off.
l
Avoid intermittent charging as the batteries develop
a memory effect similar to Nicad batteries.
BATTERY CHARGING
Batteries do not have their full potential until they have
been through 50 charge/discharge cycles (however the
rate at which the potential increases is exponential, and the
batteries will normally have 95% potential after 15 charge/
discharge cycles). Hence do not use a new battery in a
battery pack that already has more than 15 cycles. Charge
batteries at the end of each work shift or sooner if
batteries have been discharged. A battery is considered to
have a faulty cell if it has less than 80% of the potential of
the other batteries in the pack while measured under load.
Charge batteries in a well-ventilated area.
Do not charge batteries in the vicinity of sparks or
flames.
Permanent damage to batteries will result if they are
not immediately recharged after discharging.
Never leave charger operating unattended for more
than two days. Keep charger dry.
Never disconnect cables from batteries when
charger is operating.
To ensure a proper charge several items must first be
checked.
1.
Correct voltage and current are available to charger.
2. Extension cord is in good condition, is no longer than
26 ft. (8 m) and is 12 ga (1.5 mm
2 ) or larger.
3. Charger will have an adequate time to allow a full
charge i.e. ensure that power supply will not be
switched off overnight.
4. A.C. Voltage Selector Switch (110/220V) is in the
correct position.
All UpRight battery operated Work Platforms, including the
TL33, are suitable for use in freezing and low temperature
conditions (to a value of -4ºF (-20ºC)). However for this
there are two provisions which must be met.
