Engine Maintenance
Servicing the Air Cleaner
This engine is equipped with a replaceable,
high density paper air cleaner element.
Check the air cleaner daily or before starting
the engine. Check for a buildup of dirt and
debris around the air cleaner system. Keep
this area clean. Also check for loose or
damaged components. Replace all bent or
damaged air cleaner components.
Note:
Operating the engine with loose or
damaged air cleaner components could allow
unfiltered air into the engine causing
premature wear and failure.
Note:
Service the air cleaner more often
under extremely dusty, dirty conditions.

Servicing Paper Element
Check the paper element every 25 hours of
operation (more often under extremely dusty
or dirty conditions). Clean or replace the
element as necessary. Replace the air
cleaner element yearly, or every 100 hours.
1. Remove the air cleaner cover (
Figure 22
).
2. Remove the air cleaner element with the
integral rubber seal (
Figure 22
).
3. Gently tap the pleated side of the paper
element to dislodge dirt. Do not wash the
paper element or use pressurized air, as
this will damage the element. Replace a
dirty, bent, or damaged element. Handle
new elements carefully; do not use if the
rubber seal or foam sleeve is damaged.
4. Clean all air cleaner components of any
accumulated dirt or foreign material.
Prevent any dirt from entering the
carburetor.
5. Install the air cleaner element with the
pleated side “out” and seat the rubber seal
onto the edges of the air cleaner base
(
Figure 22
).
6. Reinstall the air cleaner cover and secure
with the two knobs (
Figure 22
).
Servicing the Engine Oil
Check the oil level daily or after every 8
hours.
Change oil after first 5 to 8 hours of use, then
every 50 hours thereafter. Change oil every
25 hours when operating the engine under
heavy load or in high temperatures.
Oil Type: Detergent oil (API service SF, SG,
SH, SJ, or higher)
Crankcase Capacity: 2.0 qt (1.9 l) when the
filter is changed
Choose a viscosity according to the table
below.
