Battery Maintenance and Safety Practices
ENSURE THAT BATTERY ACID DOES NOT COMES INTO CONTACT WITH
SKIN OR CLOTHING. WEAR PROTECTIVE CLOTHING AND EYEWEAR
WHEN WORKING WITH BATTERIES. NEUTRALIZE ANY BATTERY ACID
SPILLS WITH BAKING SODA AND WATER.
BATTERY ACID RELEASES AN EXPLOSIVE GAS WHILE CHARGING,
ALLOW NO OPEN FAMES, SPARKS OR LIGHTED TOBACCO PRODUCTS
IN THE AREA WHILE CHARGING BATTERIES. CHARGE BATTERIES
ONLY IN A WELL VENTILATED AREA.

SECTION 6 – GENERAL SPECIFICATIONS & OPERATOR MAINTENANCE
As with any wet cell battery, check the electrolyte level of the
batteries often, using the floats in the center of each cell filling.
Figure 6-4. Level Indicators
1. Float does not emerge - Insufficient Level
2. Float emerges - Correct Level
Add distilled water only when required.
ADD ONLY DISTILLED WATER TO BATTERIES. FILL BATTERIES ONLY
AFTER CHARGING (DURING CHARGE, ELECTROLYTE LEVEL INCREASES
AND CAN OVERFLOW).
- Fill the reservoir (1) with distilled water.
- Depress and hold the filling pump activation button (2).
- Release the button when the flow indicator (3) slows down.
- Ensure the level is correct in each cell.

Battery Voltage and Electrolyte Specific Gravity
NOTE: Voltage and specific gravity measures should not be per-
formed after battery cells have been filled. These measures must be done after a complete charge, once the
charger has been unplugged and after the battery has
been standing for at least 15 minutes.
- Open the filling cap of the cell on which the red cable is
connected (B+).
- Using the hydrometer (supplied with the machine), take a
quantity of electrolyte sufficient so that the float emerges.
Ensure that the float top does not touch the rubber bulb
or that the float does not stick by capillarity to the glass
wall.
- Read the value as indicated in Figure 6-8.
- Return electrolyte in the cell and record the value in the
battery service log.
- Measure the cell voltage and record the value in the battery service log.
- Repeat operation for each cell in sequence from B+ (Red
Cable) to B- (Black cable).
NOTE: If important disparities are noticed between gravity/volt-
age of different cells or if the gravity values are lower than
1.240kg/l (after a complete charge) contact JLG Product
Support.

SECTION 6 – GENERAL SPECIFICATIONS & OPERATOR MAINTENANCE
Filling System Maintenance
Batteries filling circuit must be serviced once a year. Cleaning
frequency must be increased in case of premature clogging of
the filter or a reduction of water flow.
- Disconnect and clean the filter (4) (See Figure 6-5.) by
reversing the water flow from the normal direction.
- Check hoses for flexibility. In case of hardening in the
connections area, replace the hose.
- Check every fittings and connections for leakage.
- Check the caps individually. Ensure perfect mobility of the
floats. In case of clogging, replace the cap.
- In any case, it is recommended to replace the caps every
2 or 3 years.
Use of a Battery in a Cold Environment
Low temperatures decrease battery capacity. The battery must
be fully charged when the machine is operated in a cold environment.
Battery Not Working Continuously or Inactive
Battery
A battery that is not used or used intermittently must be stored
charged in a dry area away from freezing temperatures. A
charge must be performed once a month.
- Disconnect the battery to insulate it electrically.
- Keep the top of the battery clean and dry to prevent selfdischarge.
IF THE BATTERY IS NOT USED CONTINUOUSLY, IT MUST BE
RECHARGED BEFORE USE AND AT LEAST ONCE A MONTH (EVEN IF THE
ELECTROLYTE SPECIFIC GRAVITY MEASURES ARE HIGH).
BEFORE RETURNING TO SERVICE A BATTERY THAT REMAIN INACTIVE
FOR A LONG PERIOD OF TIME, CHARGE THE BATTERY AND CHECK
ELECTROLYTE LEVEL IN THE CELLS.

6.7TIRES & WHEELS
Tire Wear and Damage
Inspect tires periodically for wear or damage. Tires with worn
edges or distorted profiles require replacement. Tires with significant damage in the tread area or side wall, require immediate
evaluation before replacing machine into service.
Wheel and Tire Replacement
Replacement wheels must have the same diameter and profile
as the original. Replacement tires must be the same size and
rating as the tire being replaced.
Use of genuine parts is recommended.
Wheel Installation
It is extremely important to apply and maintain proper mounting
torque.
WHEEL LUG NUTS MUST BE INSTALLED AND MAINTAINED AT THE
PROPER TORQUE TO PREVENT LOOSE WHEELS, BROKEN LUG NUTS,
AND POSSIBLE SEPARATION OF WHEEL FROM THE AXLE. BE SURE TO
USE ONLY THE LUG NUTS THAT MATCHED TO THE CONE ANGLE OF THE
WHEEL.
Tighten the lug nuts to the proper torque to prevent wheels from
coming loose. Use a torque wrench to tighten the fasteners.
Over-tightening will result in breaking the lug nuts or permanently deforming the mounting holes in the wheels. The proper
procedure for attaching wheels is as follow:
1. Start all lug nuts by hand to prevent cross threading. DO
NOT use a lubricant on threads or nuts.
2. Tighten lug nuts in the following sequence.
Figure 6-11. Wheel Lug Nut Tightening Sequence
31210088– JLG Lift –6-19
Page 90
SECTION 6 – GENERAL SPECIFICATIONS & OPERATOR MAINTENANCE
3. The tightening of the lug nuts should be done in stages.
Following the recommended sequence, tighten lug nut
per wheel torque.
