tightened in the upright position before starting
engine and do not operate the unit if the engine stop
lever is damaged or not functioning correctly.

optimum speed. It will also stop the engine and the
rotation of the cutting blades when released:
2.Engine On/Off Switch / Throttle Cable
The switch is connected to the ignition system with on
and off positions. The throttle is set up to provide the
optimum engine speed when the stop lever is fully
squeezed against the handle and stop the engine
when released –THIS CAN BE ADJUSTED USING
THE CABLE ADJUSTMENT:
Mower Operation
Make sure the ground is flat and clear of debris and
do not attempt to start on a sloped / inclined surface.
Make sure the fuel tank cap is properly installed and
tightened.
NOTE: FOLLOWING IS A SUMMARY OF THE

Mower Operation (continued)
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.Make sure the engine
stops completely when releasing the lever.
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. Avoid
operating 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):
If striking a foreign object,
stop the engine, remove wire
from spark plug, thoroughly
inspect mower for damage.
Repair damage before
restarting engine. Watch out
for traffic when working near
roadways.
For best performance, install
new blades before the cutting
season begins. Replace the
blades when necessary, with
replacement blades.
Stop the mower and allow the engine to cool before
making inspections or adjustments, and when
transporting. If the engine does not stop, move the
CHOKE lever to the starting (closed) position. Have
the unit immediately inspected by an Authorized
Service Dealer.
3. Cutting Height Adjustment
The unit’s cutting height is adjusted by removing the
cutting blade and placing the spacers on either side:
Tri-Blade Bar Blade**
Loosen and remove center bolt to disassemble the
components. Placing all the spacers above the blade
will provide the lowest cutting height; placing all the
spacers below will provide the highest cutting height.
IMPORTANT! Always install the tri-blade assembly with
flail blade mounting nuts facing upward (toward impeller
/ engine). The mounting components: hub, spacers, tri-
blade assembly / bar blade and flange, must be
installed, aligned, and seated properly before tightening
the bolt.
4. Transporting
An optional wheel kit (order #4041500) is available for
quick and easy transporting:
