40 MAINTENANCE
9/235HA, 10/215HA
AIR FILTER ELEMENT
The air filter should be inspected regularly (refer to the SERVICE/
MAINTENANCE CHART) and the element replaced when the
restriction indicator lamp illuminates. The dust collector box(es) should
be cleaned daily (more frequently in dusty operating conditions) and
not allowed to become more than half full.
The safety element should be renewed every 2000 hours or every
other main filter element change, whichever comes first.
Removal
Clean the exterior of the filter housing and remove the filter element by
releasing the nut.
If the safety element is to be renewed, thoroughly clean the interior of
the filter housing prior to removing the safety element.
Inspection
Check for cracks, holes or any other damage to the element by holding
it up to a light source, or by passing a lamp inside.
Check the seal at the end of the element and replace if any sign of
damage is evident.
Reassembly
Assemble the new element into the filter housing ensuring that the seal
seats properly.
Secure the element in the housing by hand tightening the nut.
Assemble the dust collector box parts, ensuring that they are correctly
positioned.
Before restarting the machine, check that all clamps are tight.
VENTILATION
Always check that the air inlets and outlets are clear of debris etc.
COOLING FAN DRIVE
Periodically check that the fan mounting bolt in the fan hub has not
loosened. If, for any reason, it becomes necessary to remove the fan
or re-tighten the fan mounting bolt, apply a good grade of commercially
available thread locking compound to the bolt threads and tighten to
the torque value shown in the TORQUE SETTING TABLE later in this
section.
The fan belt(s) should be checked regularly for wear and correct
tensioning.
FUEL FILTER MAINTENANCE
1. Primary fuel filter / water separator (30 microns).
Primary fuel filter / water separator
The fuel filter water separator contains a filter element which should be
replaced at regular intervals (see the SERVICE/MAINTENANCE
CHART).
Unscrew the element from the head taking care not to spill fuel inside
the machine. Remove fuel sensor (where fitted) and re-fit to new filter
element.
Discard the old element into a suitable container.
Using a clean cloth, wipe the sealing face of the filter/separator head
to ensure correct seating of the sealing ring.
Fill the element/bowl assembly with clean fuel oil then apply a light coat
of clean engine oil to the new element sealing ring.
Screw the new element onto the head firmly by hand.
The engine has a self priming system that purges air from the fuel
system.
AUTOMATIC FUEL SUPPLY
The engine has an electric fuel priming pump. After a filter change, let
the lift pump run it’s 30 second cycle before cranking.
HOSES
All components of the engine cooling air intake system should be
checked periodically to keep the engine at peak efficiency.
At the recommended intervals, (see the SERVICE/MAINTENANCE
CHART), inspect all of the intake lines to the air filter, and all flexible
hoses used for air lines, oil lines and fuel lines.
Periodically inspect all pipework for cracks, leaks, etc. and replace
immediately if damaged.
CAUTION: Never remove and replace element(s) when the machine
is running.
CAUTION: If inspection reveals damage to the main element, the
safety element must be replaced.
CAUTION: Safety elements must not be cleaned or re-used.
CAUTION: NEVER clean by blowing air inwards.
