4.
Clean the inside of the air-cleaner cover with
compressed air.
5.
Gently slide the primary filter out of the
air-cleaner body
Note:
Avoid knocking the filter into the side of
the body.
6.
Remove the safety filter only to replace it.
Inspecting the Filters
1.
Inspect the safety filter. If it is dirty, replace both
the safety and primary filters.
Important:
Do not attempt to clean the
safety filter. If the safety filter is dirty, then
the primary filter is damaged.
2.
Inspect the primary filter for damage by looking
into the filter while shining a bright light on the
outside of the filter. If the primary filter is dirty,
bent, or damaged, replace it.
Note:
Holes in the filter appear as bright spots.
Do not clean the primary filter.
Installing the Filters
Important:
To prevent engine damage, always
operate the engine with both air filters and the
cover installed.
1.
If you are installing new filters, check each filter
for shipping damage.
Note:
Do not use a damaged filter.
2.
If you are replacing the inner filter, carefully slide
it into the filter body
3.
Carefully slide the primary filter over the safety
filter
(Figure
40).
Note:
Ensure that the primary filter is fully
seated by pushing on the outer rim while
installing it.
Important:
Do not press on the soft, inside
area of the filter.
4.
Install the air-cleaner cover and secure the
latches

Servicing the Engine Oil
Service Interval: Before each use or daily
Every 100 hours (more often in dirty or dusty
conditions).
Every 200 hours—Change the engine-oil filter
(more often in dirty or dusty conditions).
Engine-Oil Specifications
Oil Type: Detergent oil (API service SF, SG, SH, SJ,
or SL)
Crankcase Capacity: 1.8 L (61 fl oz) without the oil
filter; 2.1 L (71 fl oz) with the oil filter
Viscosity: See the table below.
Note:
Although 10W-40 engine oil is recommended
for most conditions, you may need to change oil
viscosity to accommodate atmospheric conditions.
Using 20W-50 engine oil in higher ambient
temperatures can reduce oil consumption.
Checking the Engine-Oil Level
Note:
Check the oil when the engine is cold.
Important:
If you overfill or underfill the engine
crankcase with oil and run the engine, you may
damage the engine.
1.
Park the machine on a level surface, disengage
the blade-control switch (PTO), and engage the
parking brake.
2.
Shut off the engine, remove the key, and wait
for all moving parts to stop before leaving the
operating position.
Note:
Ensure that the engine is cool so that the
oil has had time to drain into the sump.
