Inspecting The Rotor Blades - Toro Power Clear 721 QZE Operator's Manual

Adjusting the Control Cable
1. Slide up the spring cover and unhook the spring from
the adjuster link (Figure

2. Z-fitting
Note: You can pull up the adjuster link and cable to
make unhooking the spring easier.
2. Move the Z-fitting to a higher or lower hole on the
adjuster link as needed to obtain the 1/16 inch to 1/8
inch (2 mm to 3 mm) gap between the control bar and
the handle (Figure
Note: Moving the Z-fitting higher decreases the gap
between the control bar and the handle; moving it
lower increases the gap.
3. Hook the spring to the adjuster link and slide the spring
cover over the adjuster link.
4. Check the adjustment; refer to
Cable (page 12).
Note: After extended use, the drive belt may wear
and lose its proper belt tension. If the drive belt slips
(continuously squeals) under a heavy load, disconnect
the spring from the adjustor link and move the upper
end of the spring to the hole that is further from
the pivot point in the control bar
connect the spring to the adjustor link and adjust the
control cable.

(Figure 27). Then
1. Remove the upper end of
spring from this hole.
2. Insert the upper end of
spring into this hole.
Note: The belt may slip (squeal) in wet conditions;
to dry out the drive system, start the rotor and run it
without a load for 30 seconds.

Inspecting the Rotor Blades

Service Interval: Yearly—Inspect the rotor blades and have
an Authorized Service Dealer replace the
rotor blades and scraper if necessary.
Before each session, inspect the rotor blades for wear. When
a rotor blade edge has worn down to the wear-indicator hole,
have an Authorized Service Dealer replace the rotor blades
and the scraper (Figure
1. The wear-indicator hole is
intact; you do not need to
replace the rotor blades.
