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.
Basic Rule
for maximum duty cycle of deep cycle
traction batteries:
z
Use the machine until it shows signs of weak / slow
performance.
z
Allow the charger to charge the batteries until it
automatically shuts off.
z
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 available to the charger.
WARNING
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
TL49, 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.
z
The ISO#46 grade of hydraulic oil normally used in
UpRight Work Platforms must be replaced with a
grade suitable for these low temperature conditions.
z
When ambient temperatures fall below 65ºF (18ºC)
batteries cannot deliver 220 Ampere hours and so
should be placed on charge as soon after use as
possible. Under such conditions a 4 hour equalize
charge once a week in the early afternoon will
improve state of charge and battery life.
Charging
1.
Check battery fluid level. If electrolyte level is
lower than 3/8 in (10 mm) above plates add
distilled water only. (
DO NOT OVERFILL
)
2.
Connect battery charger lead to properly
earthed outlet of correct voltage and frequency.
3.
The Charger will turn on automatically after a
short delay. The LED’s will indicate the rate
of charging.
4.
Charger turns off automatically when batteries
are fully charged.
HYDRAULIC OIL
With the Platform fully lowered i.e. stowed, oil should be
visible on the dipstick. If oil is
NOT
visible, fill the tank
until oil is then visible on the dipstick.
DO NOT
fill above
the upper line on the dipstick or when the platform is
elevated.
LUBRICATION
Refer to the Service & Parts Manual for the lubrication
chart and guidelines.
DECALS
Refer to Figure 9 on Pages 12 & 13 for the locations of the
Decals used on the TL49 Work Platform. These Decals
must be present and in good condition before operating the
Work Platform. Be sure to read, understand and follow
these Decals when operating the Work Platform.
