Toro 41568 Operator's Manual page 25

If you leave the key in the ignition switch, someone could accidentally start the engine and
seriously injure you or other bystanders.
Remove the key from the ignition and disconnect the wire(s) from the spark plug(s) before you
do any maintenance. Set the wire(s) aside so that it does not accidentally contact the spark
plug(s).
Jacking the Sprayer
Whenever the engine is run for routine maintenance and/or
engine diagnostics, support the rear wheels of the sprayer
1 inch (25 mm) off of the ground with the rear axle on jack
stands.
Danger
A sprayer on a jack may be unstable and slip off of
the jack, injuring anyone beneath it.
Do not start the engine while the sprayer is on a
jack.
Always remove the key from the ignition before
getting off of the sprayer.
Block the tires when the sprayer is on a jack.
The jacking point at the front of the sprayer is under the
front axle, directly under the leaf springs (Fig. 25)

Inspecting the Wheels/Tires
Check the wheels to ensure that they are mounted securely
after the first 1 to 4 operating hours and then every 100
hours thereafter. Torque the front bolts to 55–65 ft-lb
(75–88 N m) and the rear lug nuts to 85–100 ft-lb
(115–135 N m).
Check the tire condition at least every 100 hours of
operation. Operating accidents, such as hitting curbs, can
damage a tire or rim and also disrupt wheel alignment, so
inspect tire condition after an accident.
Servicing the Air Cleaner
Check the air cleaner body for damage which could
possibly cause an air leak. Ensure that the dust cap is
sealing tightly of the air cleaner. Replace a damaged air
cleaner body.
Squeeze the vacuator (Fig. 28) before each use to clear it of
dust and debris.
Service the air cleaner filter every 100 hours.
Note: Service the air cleaner more frequently if operating
conditions are extremely dusty or sandy.
