Special Tools
Most repairs can be made using normal hand tools. However, the use of a powered screwdriver will prove
invaluable.
A volt/ohmmeter is necessary for troubleshooting the electrical system. A good digital meter will simplify taking the
necessary readings.
120 VAC models will require high potential testing after making repairs to the electrical components.

struck by the lawn mower blade can cause severe
injuries to persons.

rubber gloves and footwear is recommended
when working outdoors.
5. Keep all guards, shields, safety devices, side
discharge chute or optional grass catcher in place.
Repair or replace damaged parts, including
decals. Never tamper with safety devices. Check
their proper operation regularly.
6. The motor and blade are designed to stop within 3
seconds after releasing the control bail. Ensure
that the control bail functions properly before each
use of mower. If the blade does not stop within 3
seconds, or if there is a grinding or scraping

WARNING:
To prevent electric shock, use only
with an extension cord suitable for outdoor use,
such as SW-A, SOW-A, STW-A, STOW-A, SJW-
A, SJOW-A, SJTW-A, or SJTOW-A.
1 1. Extension Cord — Make sure your extension cord
set is in
good condition. When using an extension
cord, be sure to use one heavy enough to carry
the current your product will draw. Refer to
Extension Cord Chart, see page 3 - 1. An
undersized cord will cause a drop in line voltage
resulting in loss of power and overheating.
12. Properly connect extension cord to mower in order
to prevent disconnection of the cord (Figure 2).
Figure 2
0663-002
13. To reduce the risk of electric shock, this mower
has a polarized plug (one blade is wider than the
other) (Fi
g
ure 3) and will require the use of a
polarized extension cord. The polarized extension
cord receptacle will fit onto the mower plug only
one way. If the extension cord receptacle does
not fit fully onto the mower plug, reverse the cord
receptacle. If the cord receptacle still does not fit,
obtain a correct polarized extension cord. A
polarized extension cord will require the use of a
polarized wall outlet. The extension cord plug will
fit into the polarized wall outlet only one way. If
the cord plug does not fit fully into the wall outlet,
reverse the cord plug. If the cord plug still does
not fit, contact a qualified electrician to install the
proper wall outlet. Do not change the mower plug,
extension cord receptacle, or extension cord plug
in any way.

g or
balance.
8. Avoid dangerous environments. Never operate
mower in wet grass or damp locations. Do not

mower toward you. Before and while moving
backwards, look behind and down for small
children.
19. Since the blade rotates for a few seconds after the
control bar is released, stay behind the handle
until all movin
g parts stop.
20. After striking a foreign object or if mower vibrates
abnormally, stop motor and disconnect extension
cord. Check mower for damage and make all
repairs before using mower again. If major repairs
are ever needed or if assistance is desired,
contact your local Authorized Toro Service Dealer.
21. Do not operate mower if it has been dropped or
dama
ged in any way. Repair any damage before

cord or yank cord to disconnect it from receptacle.
Keep cord away from heat, oil, and sharp edges.
25. Stop the motor, wait for all moving parts to stop,
and disconnect extension cord from mower before
adjusting the height-of-cut.
26. Stop the motor when pushing the mower outside
the lawn area.
27. Stop the motor and disconnect extension cord
from mower before removing side discharge chute
or optional grass catcher.
28. Stop motor before leaving the operator's position

from mower if mower will be unattended.
29. If mower must be lifted to be transported, stop
motor, stay behind the handle until all moving
parts stop and disconnect extension cord from
mower.
Maintenance And Storage
1. Perform only those maintenance instructions
described in this manual. If major repairs are ever
needed or if assistance is desired, contact your

adjusted, stop motor and wait for all movin
g parts
to stop. Disconnect extension cord from mower.

condition, frequently check and keep all nuts,
bolts, and screws tight. Ensure blade bolt is
tightened to 45-50 ft.lbs. (61-68 N·m).
4. Always keep a sharp blade on your mower. When
servicing blade, refer to blade maintenance
section for correct installation and servicing
procedures. Use identical replacement blades

wear or deterioration. Replace with a new bag
when worn or damaged for your protection.
9. At the time of manufacture, the mower conformed
to the safety standards in effect for rotary mowers.
To assure best performance and continued safety
certification of the mower, use
genuine Toro
