I. GENERAL OPERATION
2. Read, understand, and follow all instructions on
the machine and in the manual(s) before starting.
3. Do not put hands or feet near or under the machine.
Keep clear of the discharge opening at all times.
4. Only allow responsible adults who are familiar
with the instructions to operate this machine.
5. Clear the area of objects such as rocks, wire, toys,

7. Do not operate machine barefooted or while wearing
sandals. Always wear substantial footwear.
8. Do not pull machine backward unless absolutely
necessary. Always look down and behind
before and while moving backward.
9. Never direct discharged material toward
anyone. Avoid discharging material against
a wall or obstruction. Material may ricochet
back toward the operator. Stop the blade
when crossing gravel surfaces.
10. Do not operate machine without the entire grass
catcher, discharge guard, rear guard, or other
safety protective devices in place and working.
11. Never leave a running machine unattended.
12. Stop the lawn mower and wait until the blade

operation and installation of accessories. Only
use accessories approved by the manufacturer.
19. The warnings and precautions discussed in this
manual cannot cover all possible conditions and
situations that may occur. It must be understood
by the operator that common sense and caution
are factors which cannot be built into this
product, but must be supplied by the operator.
20. Maintain labels and nameplates on the appliance.
These carry important safety information.

up and down. Exercise extreme caution
when changing direction on slopes.
2. Watch for holes, ruts, bumps, rocks, or other
hidden objects. Uneven terrain could cause a slip
and fall accident. Tall grass can hide obstacles.
3. Do not mow on wet grass or excessively
steep slopes. Poor footing could
cause a slip and fall accident.
4. Do not mow near drop offs, ditches,
or embankments. You could lose
your footing or balance.
III. CHILDREN
Tragic accidents can occur if the operator is not alert to the presence of children.
Children are often attracted to the machine and the mowing activity.
Never assume that children will remain where you last saw them.
1. Keep children out of the mowing area and
under the watchful care of a responsible
adult other than the operator.
2. Be alert and turn mower off if a child enters the area.
3. Never allow children to operate the machine.

Check their proper operation regularly. Never
do anything to interfere with the intended
function of a safety device or to reduce the
protection provided by a safety device.
3. Keep machine free of grass, leaves, or other debris
build up. Allow machine to cool before storing.
SAVE THESE INSTRUCTIONS.
5. Check grass catcher components and the discharge
guard frequently and replace with manufacturer’s
recommended parts, when necessary.
6. Mower blades are sharp. Wrap the blade or wear
gloves, and use extra caution when servicing them.

and warrants to the original purchaser that this product is free from defects in materials and workmanship for the
period of 90 days from the date of purchase. This warranty does not apply to damage due directly or indirectly,
to misuse, abuse, negligence or accidents, repairs or alterations outside our facilities, criminal activity, improper
installation, normal wear and tear, or to lack of maintenance. We shall in no event be liable for death, injuries
to persons or property, or for incidental, contingent, special or consequential damages arising from the use of
our product. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the
above limitation of exclusion may not apply to you. THIS WARRANTY IS EXPRESSLY IN LIEU OF ALL OTHER

To take advantage of this warranty, the product or part must be returned to us with transportation charges

If our inspection verifies the defect, we will either repair or replace the product at our election or we may
elect to refund the purchase price if we cannot readily and quickly provide you with a replacement. We will
return repaired products at our expense, but if we determine there is no defect, or that the defect resulted
from causes not within the scope of our warranty, then you must bear the cost of returning the product.
This warranty gives you specific legal rights and you may also have other rights which vary from state to state.
