Breaking in a New Machine
Service Interval:
After the first 100 hours—To provide
proper performance and long
sprayer life, follow these guidelines
for the first 100 operating hours:
•
Check the engine-oil and fluid levels regularly
and be alert for indications of overheating in any
component of the sprayer.
•
After starting a cold engine, let it warm up for about
15 seconds before accelerating.
•
To optimize the brake system, burnish (break in)
the brakes as follows:
1.
Load 454 L (120 US gallons) of water into
the tank.
2.
Move the machine to an open-level area.
3.
Drive the machine at full speed.
4.
Apply the brakes rapidly.
Note:
Stop the machine in a straight line
without locking up the tires.
5.
Wait 1 minute to allow the brakes to cool.
6.
Repeat steps
through
an additional 9
times.
•
Avoid racing the engine.
•
Vary the sprayer speed during operation. Avoid
fast starts and quick stops.
•
Refer to
Maintenance (page 41)
for any special,
low-hour checks.
Preparing the Sprayer
Selecting a Nozzle
Note:
Refer to the nozzle-selection guide that is
available through your authorized Toro distributor.
The turret bodies can accept up to 3 different nozzles.
To select the desired nozzle, perform the following:
1.
Stop the sprayer on a level surface, shut off the
engine, and engage the parking brake.
2.
Set the master section switch to the O
FF
position
and set the spray-pump switch to the O
FF
position.
3.
Rotate the turret of the nozzles in either direction
to the correct nozzle.
4.
Perform a flow calibration; refer to
the Sprayer Flow (page 27)
.
Selecting a Suction Filter
Standard Equipment:
50 mesh suction filter (blue)
Use the suction filter table to identify the screen
mesh for the spray nozzles you are using based
on chemicals products or solutions with a viscosity
equivalent to water.

*The mesh size of the suction filters in this table
are based on spray chemicals or solutions with the
viscosity equivalent to water.
Important:
When you spray with higher viscosity
(thicker) chemical products or solutions with
wettable powders, you may need to use an coarser
screen mesh for the optional suction filter; refer
to
.
