9.6. CHECKING STORAGE BATTERY ELECTROLYTE LEVEL
Storage battery electrolyte level should be between MIN and MAX marks
(Fig. 9.6) on the semitranslucent battery housing and in case of their absence
— to the lower edge of the filler hole.

If the electrolyte level is below the standard it is necessary to remove cov

up to the re
quired level; then screw in plugs

having preliminary checked the vent holes
in them for cleanness and place back cover

. After that wipe the battery outer
surfaces with clean rugs soaked in 10% solution of ammonia spirit or sodium
bicarbonate.
Always keep the battery terminals and cable clamps clean as well as make
sure that they are securely tightened.
Care should be taken to ensure correct polarity when the battery is recon
nected after removal from the vehicle (positive terminal is bigger than nega
tive).
Prior to installation on the vehicle charge the battery bringing the density
up to 1.25–1.27 g/cm

. Depending on climatic zone of the vehicle operation
the electrolyte density should be corrected (see storage battery operating in
structions).
During the prolong parking of the vehicle disconnect the storage battery
from the vehicle frame to ensure fire safety precautions.

. To disconnect the storage battery during the prolong park
ing or the repairing of electric equipment the battery switch is installed under
the hood on the battery plate. It operates by short pressing on the button
