Be sure to memorize location of individual parts when 

disassembling generator so that generator can be 

reassembled correctly. Tag disassembled part with 

necessary information to facilitate easier and smoother 

reassembly.
For more convenience, divide parts into several groups 

and store them in boxes.
To prevent screws from being misplaced or installed 

incorrectly, replace them temporarily to their original 

position.
Handle disassembled parts with care; clean them before 

reassembly using a neutral cleaning 

fl

 uid.

Remove battery before disassembling generator. 

(Electric start models).
Be sure to attach foam rubber linings inside covers on 

their original position when reassembling generator. 

When deformation or damage of foam rubber lining is 

found, replace it with new part. Failure to do so will result 

in poor performance and durability of generator.
Tie wires and fuel hoses using cable ties as they were in 

original con

fi

 guration.

Remove Fuel Tank

1.  Close fuel valve and remove fuel hose from 

carburetor. Drain fuel into an approved container.

2.  Disconnect fuel hose from fuel valve.
3.  Remove screws from fuel tank, and remove fuel 

tank.

WARNING

Electrical Shock can cause injury.

Do not touch wires while generator is running.

Never operate generator in rain or snow.
Never touch generator with wet hands or electrical 

shock may occur.

NOTE:  When removing wiring terminals from wiring 

board, it may be helpful to document the order.

1.  Remove end cover.
2.  Disconnect wire connections from alternator.
3.  Remove wire terminals from wiring board.

 

WARNING

Before working on engine or equipment, disable engine as 

follows: 1) Disconnect spark plug lead(s). 2) Disconnect 

negative (–) battery cable from battery.
Do not allow children to operate generator.

Accidental Starts can cause severe injury 
or death.

Disconnect and ground spark plug lead(s) 

before servicing.

4.  Disconnect wiring from control panel to engine.
5.  Remove screws securing control panel to frame.
6.  To access inside control panel, remove screws 

securing control box to control panel.

Remove AVR

1.  Remove screws attaching AVR to rear cover and 

remove AVR unit.

Remove Brush Holder

1.  Remove screw attaching brush holder to rear cover 

and remove brush holder.

Inspection

1.  Inspect brushes for freedom of movement in brush 

holder.

2.  Check continuity between each brush tip and its wire 

terminal.

3.  Inspect brush-to-rotor contact surface for unusual 

wear or contamination.

4.  Check brush free length. Replace the brush 

assembly if the length is less than 3/16 in.(5 mm).

Remove Stator

NOTE:  Take care not to damage stator coil and rotor 

coil when removing/installing them.

NOTE:  Place stator core side down. Do not set stator on 

coil end. Coils may be damaged.

NOTE:  It may be easier in some instances to tip 

generator set on a side. Ensure oil is drained 

from engine prior to doing this.

NOTE:  Rear cover and stator are screwed together. Do 

not loosen or remove screws. Remove rear 

cover from stator after separated from alternator.

NOTE:  Stator is heavy; be prepared to handle the 

weight to maneuver for inspection and service.

1. Remove 

nuts 

fi

 xing rear cover onto rubber mounts.

2. Remove 

stator.

 

a.  Remove stater and rear cover as an assembly.

 

b.  Remove screws connecting rear cover and stator. 

3.  Remove rear cover.

Remove Rotor

1.  Remove through bolt of rotor.
2.  Place a wooden block or similar material under rotor 

to support weight as rotor is removed.

3.  With a rubber mallet, tap rotor a few times. Rotor
