2. Place a block of sucient height under the left
rear corner of the deck housing to remove
tension from the left rear deck support chain.
Detach the left rear deck support chain by
removing the upper bolt from the height ad-
juster arm. Remove the block and let the deck
hang from the remaining three support chains.
3. Measure the side-to-side level of the deck by
measuring from the ground to the top of the
deck housing at the front corners of the deck
as shown in the DS60-3 Deck Leveling illus-
tration. The side-to-side measurements
should not vary by more than 1/8 in. (3 mm).
If necessary, raise or lower the left and/or right
front support chain clevises to level the deck.
4. Measure the front-to-rear level of the deck
using a straight edge as shown in the DS60-3
Deck Leveling illustration. The rear measure-
ment should be 1/4 in. (6 mm) to 3/8 in. (10
mm) higher than the front measurement. If
necessary, adjust the right side height adjust-
ment rod by lengthening it to lower the back of
the deck, or shortening it to raise the back of
the deck.
5. With the side-to-side and front-to-rear deck
level correct, reattach the left rear support
chain that was removed in step 2. Adjust the
left side height adjustment rod to equalize the
left rear and right rear support chain tension.
6. Assure that all fasteners are tight and replace
any guards removed during the leveling proce-
dure.
PREOPERATING CHECKLIST
Before operating the mower for the rst time, and
as a routine before daily operations, it is important
to make sure the mower is properly prepared and
ready for operation. The following is a list of items
to be checked. (For a mower with frequent opera-
tion, some of these items will not need to be
checked every day, but the operator should be
aware of the condition of each.)
For proper fuel and lubricants refer to Specica-
tions on page 3.
F FILL FUEL TANK
Fill the fuel tank using clean, fresh automotive
grade unleaded gasoline (87 octane mini-
mum, 10% ethanol maximum).
DANGER
Handle gasoline with care. Gasoline is
highly ammable and its vapors are explo-
sive. Use safe refueling procedures:
● DO NOT ll fuel tank with the engine
running.
● If the engine is hot, allow to cool before
refueling.
● Use an approved fuel container.
● Fuel the mower outdoors.
● DO NOT smoke while refueling.
● Avoid spilling fuel; use a funnel or
spout.
● DO NOT overll the fuel tank; ll up to
about 1 in. (25 mm) below the top of
tank.
IMPORTANT: DO NOT permit dirt or other
foreign matter to enter the fuel tank. Wipe dirt
from around the ller cap before removing.
Use a clean fuel storage container and funnel.
IMPORTANT: DO NOT mix oil with gaso-
line. Always use fresh, automotive grade
unleaded gasoline. DO NOT use gasoline
containing greater than 10% ethanol. DO
NOT use additives, such as carburetor clean-
ers, deicers, or moisture removing agents.
DO NOT use gasoline blended with methyl
alcohol.
F CHECK ENGINE CRANKCASE OIL LEVEL
Check the engine crankcase oil level before
use and after each 8 hours of continuous
operation. Refer to Checking Engine Crank-
case Oil Level on page 52.
F CHECK AND SERVICE ENGINE AIR CLEAN-
ER SYSTEM
Check condition, cleanliness, and security of
the complete air cleaner system (inspect air
lter paper element every 100 hours). For
detailed procedures, refer to Engine Air Clean-
er System on page 59.
