Allow engine to cool before servicing spark arrestor!

Do not operate engine while servicing spark arrestor!

For machines with separate spark arresting unit:

Service the spark arrestor every 100 hours of opera- tion or twice a year, which ever occurs first.

Service as follows:

1.Stop engine and allow to cool.

2.Loosen clamp and remove spark arrestor from machine.

3.Remove locknut on top of spark arrestor housing and lift off cap.

4.Separate plates and clean if necessary.

5.Inspect plates and housing for holes or cracks. Replace spark arrestor if damaged.

6.Assemble spark arrestor using reverse order: step 3, then step 2.

For machines with integral spark arresting muf- flers:

Service spark arrestor every 250 hours.

Service as follows:

1.Stop engine and allow to cool.

2.Remove clean out plug from the side of the spark arrestor.

3.Without damaging the spark arrestor, gently tap on the shell near the clean out plug.

4.Once particles are removed, replace the clean out plug.

GFCI RECEPTACLE TESTING AND RESET- TING PROCEDURE

The GFCI receptacle should be properly tested at least once every month or whenever it is tripped. To proper- ly test and reset the GFCI receptacle:

•If the receptacle has tripped, first carefully remove any load and check it for damage.

•If the equipment has been shut down, it must be restarted.

•The equipment needs to be operating at high idle speed and any necessary adjustments made on the control panel so that the equipment is providing at least 80 volts to the receptacle input terminals.

•The circuit breaker for this receptacle must not be tripped. Reset if necessary.

•Push the "Reset" button located on the GFCI recep- tacle. This will assure normal GFCI operation.

•Plug a night-light (with an "ON/OFF" switch) or other product (such as a lamp) into the GFCI receptacle and turn the product "ON".

•Push the "Test" button located on the GFCI recepta- cle. The night-light or other product should go "OFF".

•Push the "Reset" button, again. The light or other product should go "ON" again.

If the light or other product remains "ON" when the "Test" button is pushed, the GFCI is not working prop- erly or has been incorrectly installed (miswired). If your GFCI is not working properly, contact a qualified, certi- fied electrician who can assess the situation, rewire the GFCI if necessary or replace the device.
