counterclockwise. See Photo 2-13. Using a clean fun­

ing at the oil fill hole. ALWAYS MAINTAIN THE OIL
LEVEL AT THE POINT OF OVERFLOWING.
G. After adding oil, securely replace the oil fill cap or
the dipstick.

IMPORTANT
Check the oil level each time before starting the
engine and after each 5 hours of continuous opera­
tion.
Change the oil after the first 5 operating hours and
every 25 hours thereafter. Change the oil more fre­
quently in extremely dusty or dirty conditions.
Clean the air cleaner after every 25 operating hours,
or sooner under extremely dusty or dirty operating
conditions.
STEP 7: Attach Engine Throttle Control
A. Parts Needed: (1) 1/4"-20 x 1 1/2" long Hex Hd.
Screw, (1) 1 /4" Lockwasher, (1) 1 /4"-20 Hex Nut, (1)
Plastic Tie (for 24" Mower Only).
B. Uncoil the throttle cable and position the throttle
control on the inside edge of the left handlebar as
shown in Photo 2-14.
NOTE: On the 22" mower (5 HP engine) the throttle
cable should be routed above the tubular frame cross­
piece located behind the engine; on the 24" mower {8
HP engine) the cable should be below the crosspiece.
See Photo 2-15.
C. Insert a 1 1/2" long screw through the handlebar
and into the metal clamp that is attached to the throttle
control. Add a 1/4" lockwasher and hex nut and
tighten securely using two 7/16" wrenches.
D. On the 24" mower only, use a plastic tie to secure
the throttle control cable and the blade control cable
(the thick, black cable that is attached to the blade drive
control on the left handlebar) to the center handlebar
brace. Locate the tie approximately in the middle of the
center brace.
