OPERATING INSTRUCTIONS
4012/16 Gas, February 1998 21
BATTERIES (PERKINS BATTERIES ARE
SUPPLIED DRY CHARGED. SEE
INSTALLATION MANUAL TSL4200 )
Check the level of electrolyte in each of the
battery cells; it should be 8-16 mm above the
plates. Using a hydrometer, check that the
batteries are fully charged. A fully charged
battery will have a specific gravity of 1.27 to
1.285, assuming the air temperature is
below 32°C.
For higher temperatures the
specific gravity will be 1.24 to 1.255. When
topping up the batteries always use pure
distilled water and always replace the plugs
after filling.
FILLING THE COOLING SYSTEM
The use of plain drinking water is not
recommended owing to chemical reactions
which can result in corrosion and furring-up
of the cooling system. A solution of either
water and universal anti-freeze or water and
corrosion preventative must be used.
Refer
to page 17 .
After installation and before the first start
remove the radiator cap
Fig. 4 by rotating it
anti-clockwise. Fill the cooling system with
the required coolant. Should the engine be
fitted with water cooled exhaust manifolds
then
these may need bleeding (see
Workshop Manual Section F7 ) . Run the
engine off-load for one minute to ensure that
the system is completely filled, then stop the
engine and top up the system to 25 mm (1")
below the top of the filter neck then replace
the cap.
HAND PROTECTION
MUST BE WORN
WHEN CHECKING ELECTROLYTE
LEVEL IN THE BATTERY. INFLAMMABLE
GAS IS GIVEN OFF BY THE BATTERY.
DO NOT CHECK WITH A NAKED FLAME.
WARNING
NEVER CONNECT
A BATTERY INTO
THE SYSTEM WITHOUT FIRST
CHECKING THE POLARITY AND
VOLTAGE.
NEVER DISCONNECT THE BATTERY
WHILST THE ENGINE IS RUNNING.
NEVER FLASH CONNECTIONS TO
CHECK FOR CURRENT FLOW.
WARNING
THE COOLING
SYSTEM IS
PRESSURISED - DO NOT REMOVE THE
FILLER CAP FROM THE RADIATOR
WHILST THE ENGINE IS HOT. HAND
PROTECTION MUST BE WORN.
