Removal (Fig. 33)
1. Before removing any parts from the hydraulic sys-
tem, park machine on a level surface, set brake, lower
attachment, and stop engine.
CAUTION
Operate all hydraulic controls to relieve system
pressure and avoid injury from pressurized hy-
draulic oil. Controls must be operated with the
ignition switch in OFF. Remove key from the igni-
tion switch.
2. Pivot seat up. Remove left and right side panels
from the machine. Remove left fender and seat (see Left
Fender (Seat Base) Removal in Chapter 6 – Wheels,
Brakes, and Miscellaneous).
CAUTION
The muffler and exhaust pipe may be hot. To
avoid possible burns, allow engine and exhaust
system to cool before working near the muffler.
3. Disconnect wire harness as follows: disconnect
blue wire from magneto terminal, disconnect blue wire
from voltage regulator, disconnect red/white wire from
fuel solenoid (Fig. 45).
4. Disconnect red positive cable cable (solenoid) from
the starter. Remove lock nut and cap screw securing
black ground wire and black battery cable (negative) to
the engine block. Pull cable and harness clear of the en-
gine (Fig. 47).
