Servicing the Air Cleaner

Service Interval:

Every 25 hours/Yearly (whichever comes

first)—Check the air cleaner for dirty,
loose, or damaged parts, and clean or
replace them if necessary.

Every 100 hours/Yearly (whichever comes
first)—Replace the air-cleaner element (more
frequently when operating the machine in dusty or
dirty operating conditions).

1.

Perform the pre-maintenance procedures; refer to
Preparing for Maintenance (page 12).

2.

Press the button on the air-cleaner cover (Figure 18)
and open the cover.

3.

Remove the old paper element.

4.

Install the new paper element in the air-cleaner housing,

not

in the cover.

5.

Install the air-cleaner cover.

Note:

Ensure that the air-cleaner cover is fully latched

into place by pulling gently on the upper corners of the
cover. If the cover comes loose, repeat steps 4 and 5.

Changing the Engine Oil

Service Interval:

After the first 5 hours

Yearly

Run the engine a few minutes before changing the oil to warm
it. Warm oil flows better and carries more contaminants.

1.

Perform the pre-maintenance procedures; refer to
Preparing for Maintenance (page 12).

2.

Tip the machine onto its side, with the dipstick down,
to drain the used oil out through the oil-fill tube (Figure
19).

Figure 19

3.

Remove the dipstick.

4.

After draining the used oil, return the machine to the
normal operating position.

5.

Pour about 3/4 of the crankcase capacity of oil into
the oil-fill tube.

Note:

Max. fill: 0.59 L (22 oz), type: 10W-30 or SAE

30 detergent oil with an API service classification of
SJ or higher.

6.

Wipe off the dipstick end with a clean cloth.

7.

Insert the dipstick into the oil-fill tube, but

do not

screw it in.

8.

Remove the dipstick and read the oil level on the
dipstick (Figure 20).
