If the clearances exceed the limit, remove the mast and repair or replace as necessary

Can the correction be made by adjusting the lift roller clearances?

If the correction can be made by adjusting the clearances, make the adjustment on vehicle

Measure the electrolyte specific gravity

Insert the hydrometer nozzle into the filler hole, and draw out the electrolyte into the outer tube.

Float the hydrometer properly within the outer tube so that it is free and not touching the upper or bottom part of the outer tube.

After allowing the bubbles in the drawn out fluid to die out, read the graduation at the part protruding above the electrolyte as shown in the illustration.

After measuring, wash the inner and outer side of the hydrometer with clean water (preferably refined water) and wipe dry with a cloth before storing. Do the same with the thermometer.

Is the electrolyte turbid or contains impurity?

If defective, take proper measures in accordance with procedures in Trouble Shooting.
