Mower Operation (continued)
1. Cold Starting
a. Set the on/off switch to “ON”
b. Press the primer bulb multiple times until fuel can
be see flowing through the return line to the tank
(clear flow with no bubbles).
c. Move the choke lever to the “CLOSED” position.
.
d. While standing on the right side of the unit, place
your foot on the edge of the deck while
simultaneously gripping the engine starter handle
and the engine stop lever against the handle to
hold the unit before pulling the recoil starter:
Mower Operation (continued)
Pull the starter rope out slowly about 6-8” before
beginning the full pulling motion and do not pull it all the
way out. After the engine has started, move choke lever
to the OPEN position, then carefully move behind the
unit while continuing to hold the stop lever against the
handle, adjusting your grip position using both hands.
Always maintain a firm grip on the handle and
engine stop lever and keep the unit in front of you.
If the engine does not start after 4-5 pulls, make sure
the on/off switch is on and repeat the priming steps.
If mower should vibrate abnormally, stop the engine
and check for the cause. Vibration is generally a
sign of an issue with the impeller fan or cutting
blade underneath the deck.
2. Mowing
Always use both hands when operating the unit.
Steep slopes are a major factor related to slip and
fall accidents, which can result in severe injury.
Operation on all slopes requires extra caution. Never
operate the mower at an angle greater than 45
degrees or above your position. If you feel uneasy
on a slope, do not mow it. Do not pull the unit
directly backwards when mowing.
•Always keep the unit below your position moving it
with side-to-side motion like a pendulum. Exercise
extreme caution when
changing direction on slopes.
•Watch for holes, ruts, bumps,
rocks, or other hidden objects.
Uneven terrain could cause a
slip and fall accident. Tall
grass can hide obstacles.
•Do not mow wet grass on
excessively steep slopes. Poor
footing could cause a slip and
fall accident.
•Take extra caution near drop-
offs, ditches, or embankments.
Wear shoes with traction as
you could lose your footing or
balance.
•When cutting steeper inclines from the top of the
slope and a longer reach is needed, never tie a rope
to the unit. Use the handle extension kit option
(order #4012561-M):
