Install the battery in the machine and connect the
battery cables; refer to Installing the Battery on

Note:
Do not run the machine with the battery
disconnected, electrical damage may occur.
Cleaning the Hopper Screens
For best clipping collection, maximum air flow through
the hopper is required. To provide maximum air flow, the
hopper screens must be kept clean.
1.
To clean the hopper screens dump the hopper to
remove grass clippings.
2.
With the door open, remove the knobs at the upper
front of the hopper and slide the screens out the rear of
the hopper (Fig. 99).

3.
Clean the screen by brushing off with your hand,
blowing with compressed air or spraying with a stream
of water.
4.
Replace the screens and secure with knobs (Fig. 99).
Close and latch the hopper door.
Cleaning the Hopper Full
Sensor
The hopper full sensor, inside the top right side of the
hopper, detects a beam of light from the transmitter to the
receiver. If the light beam is blocked the sensor buzzer
sounds. If the lenses are covered with clippings or debris it
may give false hopper full signals and needs to be
cleaned.
Note:
There are two different positions the hopper full
sensors can be mounted. The lower position will signal the
hopper full alarm earlier and prevent plugging of the chute
and blower.
1.
To clean the hopper full sensor dump the hopper to
remove grass clippings.
2.
With the door open, wipe off the lenses of both the
transmitter and receiver with a soft cloth or paper
towel (Fig. 100).
3.
To test the hopper full sensor for proper operation turn
the ignition key and PTO switch to on, but do not start
the engine. Place a piece of heavy cardboard in front
of the transmitter to block the light beam (Fig. 100).
The alarm buzzer should sound.
Note:
Do not use your hand to test for proper sensor
operation as the light beam may pass through or around
your hand and not properly activate the sensor.

Note:
Make sure the wire between receiver and
transmitter is tight. It can collect debris and give a false
hopper full signal.
