CORDLESS Electric Mower Safety & Operating Instructions 6
Electronic Cut-Out Switches
Circuit Breaker
A circuit breaker is located to the left of the power
key on top of the mower. This breaker may trip
when cutting heavy or thick grass, or when a wire
short-circuits. You know the circuit breaker has
tripped if the mower will not run and the white
circuit breaker reset button is projecting up into the
transparent rubber boot
. If this happens, reset the
breaker by depressing the reset button (Figure 12) .
If the circuit breaker does not reset or if it trips
repeatedly under normal cutting conditions, call one
of our Customer Service Representatives
TOLL-
FREE 1(800) DR-OWNER(376-9637).
Note: If the circuit breaker trips during the operation of the mower, allow the electric motor to cool
for at least one minute before resetting the breaker.
Low-Voltage Cut-Out Switch
The motor is equipped with an electronic cut-out switch. This device stops the mower if the battery
charge becomes excessively low and the blade speed becomes slow after an extended period of
mowing. Before restarting the mower, replace the battery pack with a fully charged battery pack (the
discharged battery pack should be recharged immediately to avoid damage).
Cutting Height Adjustment
Adjust cutting height to cut 1" to 2" of grass at a
time. The cutting height adjustment handle is
located on the right side of the deck
(Figure 13).
The handle may be placed in one of five cutting
height positions. Pull the handle toward the wheel
and then either push it forward to raise the cutting
height or pull it back to lower the cutting height.
For rough or uneven lawns, move the height
adjustment handle to a greater cutting height.
