MAINTENANCE PROCEDURES
4012/16 Gas, February 1998 29
BATTERIES
Remove the plugs or 'quick fill' covers and
check the level of electrolyte. It should be
approximately 3 mm above the top of the
plates. If it is low, top-up with pure distilled
water. Replace the plugs and wipe the top
of the battery clean and dry
(see page 21
for fuller information) .
NOTE: Check the specific gravity (see
Maintenance Schedule ).
RADIATOR
If the engine is working in dirty or dusty
conditions check that the air passages in the
radiator are not becoming choked. They can
be cleaned out by blowing compressed air in
the direction opposite to that of the normal
air flow.
DRAINING WATER FROM THE SUMP
(FOR ENGINE OPERATING ON
LANDFILL GAS)
Unscrew the drain plug in the sump and
drain off the accumulated water content until
oil flows.
Tighten the plug, check the oil
level and add the required oil.
FENNER TAPE LOCK BUSHES
MAINTENANCE INSTRUCTIONS
Experience has shown that taper lock
bushes as fitted in the fan pulleys and battery
alternator driven pulley can work loose
shortly after being put into service. Check
using a hexagon wrench to tighten allen
screws (1)

until all are tightened to the required torque
(see Torque Settings on pages 11 - 13 ) .
