MAINTENANCE
Replacing the Air Filter
If the engine seems weak or runs unevenly, 
the air filter may be clogged. If run with a dirty 
air filter, the spark plug can become fouled.
For this reason, it is important to replace the air 
filter regularly (see the heading Maintenance 
Schedule for the proper service interval).
Check the air cleaner daily or before starting 
the engine. Check for build-up of dirt and 
debris around the air cleaner system.Keep 
this area clean. Also check for loose or 
damaged components. Replace all bent 
damaged air cleaner components.
Cleaning/replacing the air filter is carried out 
as follows:
Briggs and Stratton engine
The air filter is replaced as follows:
1. Remove the air filter cowling
2. Remove the filter cartridge.
3. Remove the foam filter (pre-cleaner). 
Clean the foam filter with liquid detergent 
and water. Squeeze dry in a clean cloth. 
Saturate with engine oil and squeeze it 
inside a clean absorbenth cloth.
4. Tap the paper filter against a fixed 
surface to remove dust. If the paper filter 
is still dirty, it must be replaced. 
5. Wipe clean the inside of air filter housing.
6. Refit the foam filter (pre filter). 
7. Mount the filter in the air filter housing.
8. Replace the cowling over the air filter 
housing.IMPORTANT INFORMATION
Operating the engine with loose damaged 
air cleaner components could allow 
unfiltered air into the engine, causing 
premature wear and failure.
IMPORTANT INFORMATION
Do not use compressed air to clean the 
paper filter.
Filters should not be oiled. They should 
be assembled dry.Remove filter8019-014

MAINTENANCE
To level deck
Adjust the deck while the mower is on a level 
surface. Make sure the tires are inflated to 
the correct pressure. See “Technical Data” 
under Transmission. If tires are under or over 
inflated, you can not properly adjust your 
deck.
NOTE:It may be easier to adjust the front lift 
linkages by removing the floor pan before any 
adjustments are made.
Side-to-side adjustment
1. Raise the deck into the four inch 4” 
(102 mm) cutting position.
2. Measure height from the bottom edge of 
the deck to the ground at both front 
corners. Distance “A” should be the 
same, or within 3/16” (5 mm) of an inch.
3. If adjustment is necessary, make 
adjustment to one side of the deck only
4. Remove the securing ring from the top 
pin and the bottom clevis pin. Push 
bottom clevis pin through deck lift 
connector while supporting deck. Adjust 
by moving the deck lift connector to a 
new hole to lower or raise that specific 
corner of the deck. The round hole 
closest to the long slot is the shorter 
length and will raise the deck, the round 
hole farthest away from the long slot is 
the longer of the two and would lower the 
deck when used.
5. Recheck measurements after 
adjustment.

MAINTENANCE
Front-to-back adjustment
To obtain the best cutting performance, the 
deck should be adjusted so the front tip of the 
blades are approximately 1/8 (3.2 mm) to 
1/4 (6.5 mm) lower than the rear tip. If the 
front tip is higher, this will create a poor 
quality of cut.
1. Check blade height with blade facing 
front to rear. Measure distance “B” at the 
front and rear tip of the blade.
2. Before making any necessary 
adjustments, check to make sure that the 
deck is level side-to-side. See “Side to 
Side Adjustment” in Maintenance 
section.
3. With the deck in the 4” (100 mm) cutting 
position, measure the front and rear tip of 
each blade while facing front to rear.
4. To adjust, loosen the jam nut on the 
yoke, remove the securing ring and push 
the clevis pin out while supporting the 
deck. To lower that specific corner, 
lengthen the rod assembly by turning the 
yoke counter clockwise. To raise that 
specific corner, shorten the rod assembly 
by turning the yoke clockwise.
5. Reinstall clevis pin and recheck 
dimension.
6. Once front to back adjustment is correct, 
reinstall securing rings and secure jam 
nuts.
IMPORTANT INFORMATION
Deck must be leveled side-to-side, prior to 
leveling front to back. If the following front 
to back adjustment is required, be sure to 
adjust both front and rear linkages equally 
so the deck will stay level side to side.
