Servicing Double-Insulated Mower; Servicing "On/Off" And Blade Brake System; Storage - Toro E120 Manual Del Operador

Note: For best performance, install new blade
before cutting season begins. During
the year, file down small nicks to
maintain the cutting edge.
POTENTIAL HAZARD
A worn or damaged blade could break and
a piece of blade could be thrown in
operator's or bystander's direction.
WHAT CAN HAPPEN
A thrown piece of blade could cause serious
personal injury or death to operator or
bystanders.
HOW TO AVOID THE HAZARD
Inspect blade periodically for wear or
damage.
Replace a worn or damaged blade.
4. REMOVING BLADE–Grasp end of blade using
a rag or thickly padded glove. Remove blade
bolt, washer and blade (Fig. 20).
5. SHARPENING BLADE – Using a file, sharpen
top side of blade and maintain original cutting
angle (Fig. 21). The blade will remain balanced
if same amount of material is removed from both
cutting edges.
IMPORTANT: Check balance of blade by
putting it on a blade balancer. An inexpensive
balancer can be purchased at a hardware
store. A balanced blade stays in a horizontal
position and an unbalanced blade settles to
the heavy side. If blade is not balanced, file
more metal off cutting edge on heavy end of
blade.
6. Reinstall sharp, balanced blade, washer and
blade bolt. Sail part of blade must point toward
top of mower housing to ensure correct
installation. Washer is curved and must be
reinstalled with curve side down as shown in
Figure 20. Tighten blade bolt to 45-50 ft-lb
(61-68 N m).

Servicing Double-insulated
Mower
In a double-insulated mower, two systems of
insulation are provided instead of grounding. No
grounding means is provided on a double-insulated
mower, nor should a means for grounding be added to
the mower. Servicing a double-insulated mower
requires extreme care and knowledge of the system,
and should be done only by qualified service
personnel. Replacement parts for a double-insulated
mower must be identical to the parts they replace. A
double-insulated mower is marked with the words
"DOUBLE INSULATION" or "DOUBLE
INSULATED." The symbol (square within a square)
may also be marked on the mower.
Servicing "On/Off" and Blade
Brake System
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 metal-to-metal noise
when the control bail is released, contact your local
Authorized Toro Service Dealer for proper "On/Off"
and blade brake adjustment or replacement.
