Storage; Troubleshooting - Gravely Tratch-O-Matic Owner's/Operator's Manual

WARNING: AVOID INJURY. Read
and understand the entire Safety
section before proceeding.
Engine Maintenance
1. Be sure to keep the engine oil at the
proper level. Check the oil level each
time you fill the fuel tank.
2. Change the oil after the first five hours of
operation. Thereafter, change oil every
25 hours of operation.
3. The engine is air cooled and must be
kept clean. Do not allow dirt and debris
to cover the engine and clog the cooling
fans.
CAUTION: Do not operate the power
rake without the air cleaner installed
properly on the engine. Dust particles
in the engine will cause rapid wear of
the cylinder walls and piston rings,
and will result in a rapid loss of power.
LUBRICATION
1. Refer to engine manual for proper
lubrication of the engine.
2. Add a few drops of oil to wheel axles
between spacers and wheels to keep
wheels properly lubricated.
3. Occasionally add a few drops of oil to
the reel brake linkage.
CAUTION: Do not work on the
Thatch-O-Matic with engine running
or idling. Bring unit to a DEAD STOP.
Remove spark plug wire from the
plug.

TROUBLESHOOTING

PROBABLE CAUSE
1. No gas in the fuel tank.
2. Fuel shut-off valve closed.
3. Engine switch is in the
OFF position.
4. Build up of dirt and
residue around
governor/carburetor.
1. Fuel shut-off valve closed.
2. Contaminated fuel supply.
IMPORTANT: NEVER spray unit with high-
pressure water or store unit outdoors. Store
unit in a cool, dry, protected location.
Cleaning
NOTE: Allow unit to cool before cleaning.
Clean unit thoroughly with mild soap and low
pressure water. Brush off dirt and debris from
all surfaces. Touch up all scratched surfaces
to prevent rust. Matching touch-up paint is
available from your Dealer. Do not use
abrasives, solvents, or harsh cleaners.
Inspection
Inspect unit and repair or replace worn or
damaged parts to avoid delays when
beginning use again.
Regularly check all hardware and keep
fasteners tight. Know unit is in safe working
condition.
Engine
When storing unit for extended periods of
time, remove all fuel from tank and carburetor
(run dry). Refer to engine manual.
Fuel System
Gasoline left in the fuel system for extended
periods without a stabilizer will deteriorate,
resulting in gum deposits in the system.
These deposits can damage the carburetor
and the fuel hoses, filter and tank. Prevent
deposits from forming in the fuel system
during storage by adding a quality fuel
stabilizer to the fuel. Follow the
recommended mix ratio found on the fuel
stabilizer container.
To treat the fuel system for storage:
1. Add fuel stabilizer according to
manufacturer's instructions.
2. Run engine for at least 10 minutes after
adding stabilizer to allow it to reach the
carburetor.
NEVER store the engine with fuel in the fuel
tank inside of a building with potential
sources of ignition.
CORRECTION
1. Fill tank with clean, fresh gasoline.
Fill fuel tank (see FILLING FUEL
TANK on page
2. Open fuel shut-off valve.
3. Turn the engine switch to ON
position.
4. Clean area around
governor/carburetor.
1. Open fuel shut-off valve.
2. Replace with clean fuel.
