7.20 CHECKING WEAR ON THE TELESCOPIC ARM SLIDES
‑ visually check the play on the extension arms.
‑ if the play exceeds 3 mm, adjust the plastic registers by screwing them tighter until they
rest on the arm (top) or reach around 1 mm from the arm (bottom). Check correct con‑
tact and distances by sliding the arm out and back completely.
‑ the slides must be replaced, where necessary, by an JLG authorised workshop.
7.21 CHECKING TIGHTNESS OF THE TURNTABLE BOLTS
Check the correct tightness of the top and bottom bolts on the turntable according to the
intervals specified in the routine maintenance table.
The bolts must be tightened to a torque of 248 Nm.
7.22 BATTERY: CHECKS AND MAINTENANCE THERMIC VERSION
‑ Do not use naked flames or produce sparks near the battery (explosive gases).
‑ The battery contains diluted sulphuric acid, which is highly explosive.
‑ Proceed with care, shielding your eyes and face.
‑ In case of accidental contact with the sulphuric acid, rinse immediately with plenty of
running water.
‑ Before working on the battery, ALWAYS disconnect the battery cutout switch.
7.22.1 CHECKING THE ELECTROLYTE LEVEL THERMIC VERSION
The battery does not need to be topped up.
However, if the electrolyte, with the machine on a level
surface, is below the minimum allowed level (MIN.), it is
possible to top up by removing the lid “A” and adding
distilled water without exceeding the maximum level
(MAX.). Only for no AGM technology battery (Absorbed
