Operation
7. Turn off the fuel valve(s) and allow the engine to
run out of fuel. Failure to do this may cause the
engine to “ood” when re-starting.
8. Turn the ignition switch to the “OFF” position
once the engine has stopped.
9. Remove the key to prevent children or other
unauthorized persons from starting engine.
Important: There are NO adjustments
necessary for the LPG mower. Do Not make any
adjustments to the regulator or carburetor. If
the engine is not running properly, contact an
Authorized Service Dealer.
Driving the Machine
Drive Lever/Neutral Lock Latch Operation
To lock the drive levers in “neutral lock”, squeeze the
drive levers to the “neutral” position (Do Not squeeze
the drive levers all the way back as this will cause the
drive wheels to go into full reverse direction). See
Figure 5 position 1. Place thumbs on the inner lobe
of the neutral lock latches and rotate them under
the drive levers into the “neutral lock” position. See
Figure 5 position 2. Release the drive levers.
CAUTION
If the neutral lock latches are not completely
engaged the drive levers could unexpectedly slip
into the forward drive position. If the drive levers
slip into the drive position the unit could lurch
forward and cause injury or property damage.
Be sure the drive levers are past the roller and
securely seated at the bottom of the neutral lock
latches.
To place the drive levers in the “forward” position,
slightly squeeze the drive levers while placing thumbs
on the outer thumb lobe of the neutral lock latches
(or the index nger on the front lobe) and rotate them
from under the drive levers. Slowly and carefully
release the drive levers. See Figure 5 position 3.
To place the drive levers in the “reverse” position,
squeeze the drive levers past the neutral position. See
Figure 5 position 4.

Driving Forward
1. Release the parking brake.
2. With drive levers locked in “neutral”, shift speed
control lever to desired forward speed.
3. Slowly squeeze and hold both drive levers in
the neutral position and rotate both neutral lock
latches from the neutral lock position to the
forward position.
Note: Do Not squeeze both drive levers all the
way back. This will cause the drive wheels to
engage in the reverse direction.
4. To move forward in a straight line, smoothly
release both drive levers to engage drive wheels.
To turn left or right, squeeze the right hand drive
lever to turn right and the left hand drive lever
to turn left.
To make a “zero turn”, squeeze either the left
hand or the right hand drive lever back into the
reverse position while the opposite drive lever is in
a forward position at an equal but opposite speed.
Note: For smooth operation of this machine,
avoid quick, jerky movements of the drive levers.
Move the drive levers smoothly and deliberately.
To stop, squeeze drive levers back to the “neutral”
position. Move the neutral lock latches into the
“neutral lock” position and release drive levers.
Move the speed control lever to the neutral
position.
