Powermate PM0141200 - Manual (Page 13)

VALVE CLEARANCE
Intake — 0.08 mm - 0.12 mm (.003 inch - .005 inch)
Exhaust — 0.13 mm - 0.17 mm (.005 inch - .007 inch)
After the first 50 hours of operation, check the valve clearance in
the engine and adjust if necessary.
NOTICE: If unsure about doing this procedure or if the proper tools
are not available, take the generator to the nearest service center to
have the valve clearance adjusted. This is a very important procedure
to ensure longest life for the engine.
SPARK ARRESTER SCREEN
Remove screen every 50 hours for cleaning and
inspection. Replace if damaged.
Clean and inspect the spark arrester as follows:
1. Remove the screen retainer by removing the retainer clamp.
2. Remove the retainer screw from the muffler outlet tube.
3. Slide the spark arrester screen out from the muffler outlet tube.
4. Be careful not to damage the spark arresting screen. The spark
arrester must be free of breaks and holes. If screen is not
damaged, clean it with a commerical solvent.
5. Replace the screen and retainer and secure with retainer screw
and clamp.
GENERATOR: Brushes
The brushes in the generator should be inspected once every year
for chips and cracks. Brushes should be replaced when they are worn
to 1/4 inch (7mm).
NOTE: Replace brushes in sets only, never separately.
Replace only with brushes specified in parts list. Other brushes
may appear to be identical but may have completely different
mechanical and electrical characteristics.
INSPECTING THE BRUSHES:
1. Remove 2 screws (V) and end cover (W).
2. Remove screw (X) holding the brush module (Y).
3. Disconnect the blue (+) and yellow (-) brush wires from the
tabs.
4. Replace if worn to 1/4 inch (7mm).
5. Do not over tighten screw.
HEAT SHIELD:
Inspect to ensure that all heat shields and heat deflectors are intact
and in place. Do not remove any parts or modify parts. Removing or
modifying parts could cause serious
damage to the unit.
ENGINE: Carburetor Icing
During the winter months, rare atmospheric conditions may
develop which will cause an icing condition in the carburetor. If this
develops, the engine may run rough, loose power, and may stall. Call
Product Service for more information.
QUICK STARTING TIPS FOR UNITS THAT HAVE BEEN
SITTING FOR AWHILE:
If your unit has been sitting around for a long time period and is
hard to start, try doing some of these easy steps before calling the
Customer Hotline.
1. Check the oil level.
2. Replace the old fuel.
3. Change the spark plug.
4. Check the fuel lines. Make sure the fuel shut off valve is open.
5. Check all generator parts for integrity.
6. Clean the Carburetor.
INFREQUENT SERVICE
If the unit is used infrequently, difficult starting may result. To
eliminate hard starting, follow these instructions:
1. Run the generator at least 30 minutes every month.
2. Run the generator, then close the fuel shut-off valve and allow
the unit to run until the engine stops.
3. Move the engine switch to the “OFF” position.
LONG TERM STORAGE
When the generator set is not being operated or is being stored
more than one month, follow these instructions:
1. Replenish engine oil to upper level.
2. Run the generator, then close the fuel shut-off valve and allow
the unit to run until the engine stops.
3. Move the engine switch to the “OFF” position.
4. After the unit has cooled, drain gasoline from fuel tank, fuel line
and carburetor.
5. Pour about one teaspoon of engine oil through the spark plug
hole, pull the recoil starter several times and replace the plug.
Then pull the starter until you feel the piston is on its
compression stroke and leave it in that position. This closes
both the intake and exhaust valves to prevent the inside of the
cylinder from rusting.
6. Cover the unit and store in a clean, dry place that is well
ventilated away from open flame or sparks.
NOTE: We recommend always using a fuel stabilizer. A fuel
stabilizer will minimize the formulation of fuel gum deposits
during storage. The fuel stabilizer can be added to the gasoline
in the fuel tank, or into the gasoline in a storage container.
