SECTION 2. MAINTENANCE
The weather station has been engineered to provide many years of reliable service. Periodic
maintenance, however, is required to help insure that the system performs up to its potential.
The following maintenance schedule is
important in the effective continuous operation
of the weather station. Log notes are included
in order to track the progress of maintenance
and record any problems. If there are any
questions about the following schedule, contact
your Toro distributor for assistance.
2.1 WEEKLY
•
Visually inspect the weather station, and all
sensors.
•
Check all sensors for visible damage or
debris.
The solar sensor may obtain bird droppings
that may disturb the sensor readings. Be
sure to clean if necessary (Section 2.3.1).
Check the rain gage for debris inside the
funnel (Section 2.2.1).
•
Look for possible cable damage on any
sensors, and record all inspection findings
in log section 2.4.
2.2 MONTHLY
2.2.1 RAIN GAGE
Check the rain gage, funnel and tip mechanism.
Be sure screen inside funnel is clean from bird
nests or debris. Remove the rain gage funnel.
The rain gage is assembled in two pieces. The
top portion (funnel) can be removed by pulling
up on the sides. Remove the rain gage funnel.
Be sure that the funnel hole is not clogged with
debris. Observe the tipping mechanism inside
the can, and be sure there are no spider webs
or bugs that have caused the mechanism to
freeze in one position.

the site that the rain gage is level. Leave the
tipping mechanism to one side (note fig). Note
that the tips will be logged by the weather
station as rain.
2.2.2 SOLAR SENSOR
