MAINTENANCE

▲c WARNING I

Disconnect spark plug wire and ground it against the engine before performing any repairs or maintenance.

ENGINE

Refer to the separate engine manual packed with your unit for all engine maintenance procedures. Read instructions carefully.

AIR CLEANER

The air cleaner prevents damaging dirt, dust, etc., from entering the carburetor and being forced into the engine and is important to engine life and performance.
Never run your engine without air cleaner completely assembled.
To service air cleaner; refer to the separate engine
manual packed with your unit.
Hold the blade retainer on the impeller assembly
5.
with an adjustable wrench to keep the blade from
turning as shown in figure 15.
6.
Remove the blade by removing the center bolt, lock washer and flat washer.
NOTE
LUBRICATION Wheels ' The wheels require no lubrication. Flails and Fingers - If the unit is disassembled for any
reason, lubricate the flails and fingers with a light oil (engine oil may be used).

CUTTING BLADE

The cutting blade may be removed for grinding or
replacement as follows.
1. Lower the upper guide extension.
2. Block up the housing. See figure 15.
3. Remove the four elastic lock nuts from the back of the housing using a 1/2" wrench. Refer to figure
13. Separate the shredder into two halves.
4. Remove the back-up plate. See figure 15.
NOTE
When reassembling, make certain the opening on the back-up plate is toward the bottom of the unit. The back-up plate may be reversed to provide a new cutting edge.
Use caution when removing the blade to avoid contacting the weld bolts protruding from the housing.
WARNING
Ai
The blade is reversible and can be assembled to the crankshaft with either side showing.
When sharpening the blade, follow the original angle of grind as a guide. It is extremely important that each cutting edge receives an equal amount of grinding tp prevent an unbalanced blade. An unbalanced blade will cause excessive vibration whèn rotating at high speeds and may cause damage to the unit.
The blade can be tested by balancing it on a round shaft screwdriver or nail. Remove metal from the heavy side
until it balances evenly. See figure 16.
When reassembling the blade, tighten to between 375 and 450 inch pounds, or lacking torque wrench, tighten securely.

FLAILS AND FINGERS

The flails and fingers may be reversed wher they become dull. It is suggested that this procedure be performed by your nearest authorized service dealer.
OFF-SEASON STORAGE
If the shredder is to be inoperative for a period longer than 30 days, the following precautions are recommended.
1. Working outdoors, drain all fuel from the fuel tank. Run the engine until it stops from lack of fuel.

WARNING
