Snapper SG 5000 - Maintenance and Storage

MAINTENANCE AND STORAGE
If the cutting mechanism strikes any foreign object or if your machine should start making an unusual noise
or vibrating, stop the engine, disconnect spark plug wire from the spark plug. Allow the engine to cool
before:
(a) . Inspect for obvious damage.
(b) Check for loose parts, bolts, or rods. Examine rotor visuaiiy for any obvious defects.
(1) Check the bearing coiiar set screws regularly to be sure they are tight.
(2) After every 100 hours of use, reiubricate the bearings (item no. 27) on both ends of the shaft with
a lithium base grease or a grease that is suitabie for ball bearings. Usuaily one or two pumps of
grease is adequate.
(3) When not in use, your machine should be stored out of the reach of children. Be sure there are no
gasoline fumes in the storage area. For long periods of storage (over winter), gasoiine should be
drained from the tank or add a gas stabilizer (ie. Stabii). Always allow the engine to cool before
storing.
(4) When the hard steel hammers become dull or round on the cutting edge, they may be reversed.
First remove the belt guard (item #26 on page 13) to expose the hammer rod access holes. One
hammer rod at a time can be removed through this side hoie and the hammers reversed as the rotor
is reassembied. Each rod is held in place by a pin (see page 17 for more information on removal
and reinstallation of pin). Extreme care must be taken to reinstall the spacers (items 6,7, & 8) in
exactly the same order as shown on the drawing. We emphasize this point. The spacers and
hammers must be reinstalled in exactly their original order (See page 14).
(5) You will find inciuded information referring to operation and maintenance of the shredder engine.
Look it over carefully. BE CERTAIN TO PUT OIL IN THE ENGINE BEFORE YOU START IT.
(6) When the steel chipping knife (item #9 page 14) needs repiacing or sharpening, remove the access
door (item 26) on the chipper side of the machine by removing (1) nut (item 40). Rotate rotor until
knife (item 9) is in the access opening. Use a 3/16" alien wrench to hold the flat head screw (item
10) on the knife side. Use 1/2" open end or box end wrench to remove the three Grip-co lock nuts
(item 25). To reinstali the knife reverse the above procedure.
(7) Care must be exercised when sharpening the blade to maintain the correct bevel and a straight
cutting edge.
