SECTION 6: OPERATION
WARNING: Keep hands and feet away
from the chute area on cutting deck. See
Figure 1 in the Safety Section.
WARNING: The operation of any lawn
mower can result in foreign objects being
thrown into the eyes, which can result in
severe eye damage. Always wear safety
glasses or eye shields. We recommend
wide vision safety mask for over
spectacles or standard safety glasses.
NOTE: For shipping purposes your mower is set
with the wheels in a low cutting height position. For
best results raise the cutting position until it is
determined which height is best for your lawn. See
cutting height adjustment section.
GAS AND OIL FILL-UP
Service the engine with gasoline and oil as
instructed in the separate engine manual packed
with your mower. Read instructions carefully.
WARNING: Never fill fuel tank indoors,
with engine running or until the engine has
been allowed to cool for at least two
minutes after running.
BEFORE STARTING
1. Attach spark plug wire to spark plug. Make
certain the metal cap on the end of the spark
plug wire (inside the rubber boot) is fastened
securely over the metal tip on the spark plug.
2.Before each use, check for proper drive clutch
operation by performing the following procedure
before starting the engine.
With the drive clutch control released, push
mower forward. It should move freely. Pull
mower backward. It should move with only a
small amount of resistance.
If it does not and the rear wheels tend to
lock up, the clutch may not be releasing
completely. Do not start the engine until
corrections have been made.
Check the control cable for severe bend, kinks
and binding, or grass build-up around the belt.
Correct and adjust as required.
Refer to instructions under "Drive Clutch Control
Adjustment" in Adjustment Section for loosening
the drive belt.
