T o troubleshoot, tur n on the k ey without star ting
the engine . Identify the specific function that does
not w ork and w ork across the logic c har t. Inspect
the condition of eac h input LED’ s to ensure it
matc hes the logic c har t.
If the input LED’ s are cor rect, c hec k the output
LED . If the output LED is illuminated but
the device is not energized, measure a v ailable
v oltag e at the output device , contin uity of the
disconnected device , and potential v oltag e on the
g round circuit (floating g round). R e pairs will v ar y
de pending on y our findings .
Operating Tips
• Practice dri ving the mac hine before initial
operation because it has a h y drostatic
transmission and its c haracteristics are different
than some turf maintenance mac hines . Some
points to consider when operating the mac hine
and dec k are the transmission, engine speed,
load on the cutting blades , and the impor tance
of the brak es .
• T o maintain enough po w er for the mac hine
and dec k while mo wing, regulate traction
pedal to k ee p engine r pm high and somewhat
constant. A g ood r ule to follo w is: decrease
g round speed as the load on the cutting blades
increases; and increase g round speed as load
on the blades decreases . T his allo ws the
engine , w orking with the transmission, to sense
the proper g round speed while maintaining
high blade tip speed necessar y for g ood
quality-of-cut. T herefore , allo w traction pedal
to mo v e upw ard as engine speed decreases ,
and de press pedal slo wly as speed increases . By
comparison, when dri ving from one w ork area
to another -with no load and dec k raised-ha v e
throttle in F ast position and de press traction
pedal slo wly but fully to attain maxim um
g round speed.
• Another c haracteristic to consider is the
operation of the brak es . T he brak es can be
used to assist in tur ning the mac hine; ho w ev er ,
use them carefully , especially on soft or w et
g rass because the turf ma y be tor n accidentally .
T he brak es can be used to control the direction
of the dec k when trimming along fences or
similar objects . T he other benefit of the brak es
is to maintain traction. F or example; in some
slope conditions , the uphill wheel slips and
loses traction. If this situation occurs , de press
uphill brak e pedal g radually and inter mittently
until the uphill wheel stops slipping; thus ,
increasing traction on the do wnhill wheel. If
inde pendent braking is not desired, eng ag e the
lev er on left brak e pedal with right pedal. T his
pro vides sim ultaneous braking at both wheels .
• Before stopping the engine , diseng ag e all
controls and mo v e the throttle to the Slo w
position. Mo ving the throttle to the Slo w
position reduces high engine speed, noise , and
vibration. T ur n the ignition k ey to the Off
position to stop the engine .
