NOTE: Do not crank engine continuously for more than 10 seconds. Allow a 60 second cool-down period between
starting attempts. Failure to follow these guidelines can burn out starter motor.
NOTE: If engine develops sufficient speed to disengage starter but does not keep running (a false start), engine
rotation must be allowed to come to a complete stop before attempting to restart engine. If starter is engaged
while flywheel is rotating, starter pinion and flywheel ring gear may clash and damage starter.
NOTE: If starter does not crank engine, shut off starter immediately. Do not make further attempts to start engine until
condition is corrected.
NOTE: Do not drop starter or strike starter frame. Doing so can damage starter.
Engines in this series use inertia drive or solenoid shift starters.
Troubleshooting-Starting Difficulties
Condition
Possible Cause
Conclusion
Starter does not energize.
Battery
Check specific gravity of battery. If low, recharge or replace
battery as necessary.
Wiring
Clean corroded connections and tighten loose connections.
Replace wires in poor condition and with frayed or broken
insulation.
Starter Switch
or Solenoid
By-pass switch or solenoid with a jumper wire. If starter cranks
normally, replace faulty components. Remove and perform
individual solenoid test procedure.
Starter energizes but turns
slowly.
Battery
Check specific gravity of battery. If low, recharge or replace
battery as necessary.
Brushes
Check for excessively dirty or worn brushes and commutator.
Clean using a coarse cloth (not emery cloth).
Replace brushes if excessively or unevenly worn.
Transmission
or
Engine
Make sure clutch or transmission is disengaged or placed
in neutral. This is especially important on equipment with
hydrostatic drive. Transmission must be exactly in neutral to
prevent resistance which could keep engine from starting.
Check for seized engine components such as bearings,
connecting rod, and piston.
