2. Air Filter Check and Change
Release the two spring clips. Pull off the end cover to reveal the filter element. The
element simply pulls out.
To fit the new element, slide the open end of the filter element into the main body.
Gently push the element until fully seated. Refit the end cover.
The air filter is constructed from pleated paper. Inspect it closely for dust or dirt. The
air filter cannot be cleaned and must be replaced when dirty. The engine requires
clean unrestricted air to run efficiently. Failure to maintain the air filter could result in
smoke, increased fuel consumption and ultimately engine damage.
3. Gearbox Oil Change
WARNING:
BURN HAZARD!
WAIT UNTIL THE GEARBOX COOLS SLIGHTLY BEFORE YOU
DRAIN THE GEARBOX OIL. HOT OIL MAY SPLASH AND BURN YOU.
Some engines will have a gearbox sump pump fitted. To change the oil in this
circumstance, follow the same procedures as were outlined for changing the engine
oil. For engines without a gearbox sump pump follow the procedure below.
Change the gearbox oil while it is still warm (Please refer to the gearbox manual for
more information).
Place a tray beneath the gearbox that will hold at least 2 litres.
Remove the drain plug and allow 5 minutes for the oil to drain thoroughly.
Replace the drain plug. Ensure that the sealing washer (if used) is still in place and in
good condition before tightening. Fit a new washer if required.
Refill the gearbox with oil to the upper mark on the dipstick. Screw the dipstick in fully,
to establish level. Refer to the PRM owner manual for more details.
Section 6
in this
manual
contains details of oil specifications.
Do not overfill the gearbox as this can damage the internal components.
