There is one safety switch in the starting circuit of your unit: the brake pedal switch.
Make certain the actuator is fully depressing the button on this switch. The Operator
must be seated on the tractor in order to start the engine, also.
The battery must be installed with negative terminal attached to black ground wire.
Negative terminal is identified at the post by "NEG", "N" or "-". The positive terminal,
identified by "POS", "P" or "+", must be attached to the thick red wire which goes to the
solenoid.
Charge at six amps with a 12-volt automotive-type battery charger for one hour or until
fully charged.
Refer to operator's manual for fuse location. Replace fuse with automotive type fuse
of the proper amperage. Fuses seldom fail without a reason. The problem must be
corrected. Check for loose connections in the fuse holder. Replace fuse holder if nec-
essary. A dead short may be in the cranking or charging circuit where the insulation
may have rubbed through and exposed the bare wire. Replace the wire or repair with
electrician's tape if the wire strands have not been damaged.
Note: Look for a wire pinched between body panels, burned by the exhaust pipe or
muffler or rubbed against a moving part.
Refer to the OPERATION section of this manual for the correct position of the throttle
control and choke for starting.
Gasoline tank empty. Fill.
Fuel line or in-line fuel filter plugged. Remove and clean fuel line. Replace fuel filter
(if so equipped) if necessary.
Spark plug lead disconnected. Connect lead. Using a spark tester, check for spark. If
no spark is present, have engine's magneto serviced by an authorized engine dealer.
If the air cleaner is dirty, the engine may not start. Refer to the engine manual packed
with your unit.
Check oil level.
Dipstick not seated or broken. Replace defective part.
Engine breather defective. Replace.
Stop engine immediately. Check all pulleys, blade adapters, keys and bolts for
tightness and spindle damage. Tighten or replace any loose or damaged parts.
Always replace damaged blade. Only use original equipment blades.
Throttle must be set at full throttle.
Use lower ground speed. The slower your ground speed, the better the quality of cut.
Raise deck.
Sharpen or replace blades (uncut strip problem only).
