SECTION 9: TROUBLE SHOOTING GUIDE
NOTE: If the above steps fail to correct the problem, contact your local authorized service dealer for repair.
Trouble Possible Cause(s) Corrective Action
Engine will
not crank 1. Safety switch
button not
depressed.
2. Battery installed
incorrectly.
3. Battery is dead or
weak.
4. Blown fuse or
circuit breaker.
5. Engine ground wire
loose.
1. There are two switches in the starting circuit of your unit: the clutch
pedal switch and the deck lift lever switch. Make certain the actuator is
fully depressing the buttons on each switch.
2. 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 big red wire which goes to the solenoid. All batteries are
to be fully charged before installing. Refer to “Quick Start” battery guide
that came with the operator’s manual.
3. Check fluid level in battery. If fluid is low, fill to just below split rings with
water. Charge with 6 AMP charger until fully charged.
4. Refer to operator’s manual for fuse box location. Replace fuse with
automotive type fuse. Fuses seldom fail without a reason. The problem
must be corrected. Check for loose connections in the fuse holder.
Replace fuse holder if necessary. 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: Note: Look for a wire pinched between body panels, burned by the
exhaust pipe or muffler or rubbed against a moving part.
5. Engine should have a black ground wire running from engine to frame
or mounting bolt.

2. No fuel to the
carburetor.
3. No spark to spark

4. Faulty spark plug.
5. Dirty air cleaner.
1. Check operator's manual for correct position for throttle control and
choke for starting.
2. A. Gasoline tank empty. Fill.
B. Fuel line or in-line fuel filter plugged. Remove and clean fuel line.
Replace filter.
3. Connect lead. Hold spark plug lead away from engine block about 1/8".
Crank engine. There should be a spark. If not, have engine repaired at
authorized engine service dealer.
4. To test, remove spark plug. Attach spark plug lead to spark plug.
Ground the spark plug body against the engine block. Crank the engine.
The spark plug should fire at the electrode. Replace if it does not.
5. If the air cleaner is dirty, the engine may not start. Refer to the engine
manual packed with your unit.
Excessive

uncut strips 1. Engine speed low.
2. Cutting height set

2. Use lower ground speed. The slower your ground speed, the better the
quality of cut.
