2.
Brush or blow out debris from the inside of the belt
cover and around all the parts.
3.
Hold a feeler gauge set between 0.005 and 0.03 inches
(0.13 and 0.76 mm) against the wall and slide it down
behind the belt tension spring; refer to Figure 31.
Figure 31
Note:
If there is a visible gap between the gauge and
the spring, tighten the adjusting bolt and the nut until
the feeler gauge barely slides freely in and out of the
gap (Figure 30).
Important:
Do not overtighten the adjusting bolt.
This could damage the blade-drive belt.
4.
Install the belt-cover-access panel.
Servicing the Cutting Blades
Service Interval:
Before each use or daily
Important:
You will need a torque wrench to install the
blades properly.
If you do not have a torque wrench or
are uncomfortable performing this procedure, contact
an Authorized Service Dealer.
Examine the blades for sharpness and any wear or damage
whenever you run out of gasoline; refer to Inspecting the
Blades (page 20). If the blade edge is dull or nicked, have it
sharpened or replace it. If the blades are worn, bent, damaged
or cracked, replace them immediately with a genuine Toro
replacement blades.
DANGER
A worn or damaged blade can break, and a piece
of the blade could be thrown toward the operator
or a bystander, resulting in serious personal injury
or death.
•
Inspect the blades periodically for wear or
damage.
•
Replace worn or damaged blades.
Note:
Maintain sharp blades throughout the cutting season,
because sharp blades cut cleanly without tearing or shredding
the grass blades. Tearing and shredding turns grass brown at
the edges, which slows growth and increases the chance of
disease.
Preparing to Service the Cutting Blades
Tip the machine onto its side, with the air filter up in the air,
until the upper handle rests on the ground.
WARNING
The blades are sharp; contacting a blade could
result in serious personal injury.
•
Disconnect the wire from the spark plug.
•
Wear gloves when servicing the blades.
Inspecting the Blades
Service Interval:
Before each use or daily
1.
Inspect the cutting edges (Figure 32). If the edges are
not sharp or have nicks, remove the blades and have
them sharpened or replace them.

2.
Inspect the blades themselves, especially the curved
area (Figure 42). If you notice any damage, wear, or
a slot forming in this area (Figure 32), immediately
replace them with new blades.
DANGER
If you allow a blade to wear, a slot will form
between the sail and flat part of the blade.
Eventually a piece of the blade may break
off and be thrown from under the housing,
possibly resulting in serious injury to you or
bystanders.
•
Inspect the blades periodically for wear or
damage.
•
Never try to straighten a blade that is bent
or weld a broken or cracked blade.
•
Check for bent blades; refer to Checking
for Bent Blades (page 20).
Checking for Bent Blades
1.
Rotate the blades until they are positioned as shown
in Figure 33.
