Charger turns on automatically after a short delay, the
ampmeter will indicate DC charging current.
4. Charger turns off automatically when batteries are fully
charged.
BATTERY CELL EQUALIZATION
The specific gravity of the electrolyte in the battery cells
should be equalized monthly. To do this, charge batter-
ies as outlined in Battery Charging. After this initial
charge, check the electrolyte level in all cells and add
distilled water as necessary. Then, turn the charger on
for an additional eight hours. During this time, the
charging current will be low (four amps) as cells are
equalizing.
After equalization, the specific gravity of all cells should
be checked with a hydrometer. The temperature
corrected specific gravity in this state should be 1.260. If
any corrected readings are below 1.230, the batteries
containing such cells should be replaced.
Do not check the specific gravity in a cell to which
water has just been added. If there is not enough
electrolyte in a fully charged cell to obtain a sample for
the hydrometer, add water and continue charging for
one to two hours to adequately mix the water and
electrolyte.
4.4 Lubrication
STEERING LINKAGE
Apply two to three drops of oil to each linkage bearing.
Use a grease gun with multipurpose grease and apply
grease to the each zerk fitting at the steering pivots.
HYDRAULIC OIL TANK AND
FILTER (Figure 4-3)
Fluid Level
With the platform fully lowered, open the Left Module
and remove the reservoir breather/cap, oil should be at
the full mark.
Oil and Filter Replacement
1. Operate the work platform for 10-15 minutes to
bring the hydraulic oil up to normal operating
temperature.
The hydraulic oil may be of sufficient
temperature to cause burns. Wear safety
gloves and safety glasses when handling
hot oil.
2. Provide a suitable container to catch the drained oil.
Hydraulic tank has a 7 liter(7.4 quart) capacity.
3. Open Left Module Door.
4. Remove the drain plug and allow all oil to drain.
Dispose of hydraulic fluid properly, contact your
local oil recycler.
5. Reinstall the drain plug.
6. Unscrew the filter from the Filter Assembly.
7. Apply a thin film of clean hydraulic oil (ISO #46) to
the gasket of the replacement filter.
8. Screw the replacement filter onto the filter head
until the gasket makes contact then rotate the filter
3
/4 of a turn further.
9. Fill the hydraulic reservoir with ISO #46 hydraulic
oil until the oil is up to the full mark on the dipstick.
