4.0 OPERATION
4.1 STARTING (TOWABLE MODEL)
Move machine to a clear level area outdoors before starting.
Do not operate machine on a paved, concrete, or gravel
surface. Do not operate in the vicinity of bystanders. Make
sure cutting chamber is empty before starting.
1. Before starting, check engine oil level and fill if neces-
sary. See engine owners manual for operation and main-
tenance instructions.
2. Before starting, fill fuel tank with fresh, clean unleaded
regular gasoline. DO NOT MIX OIL WITH GASOLINE.
3. Disengage clutch lever by pressing foot clutch pedal.
4. Place engine throttle lever at 3/4 - full open position.
Place engine choke lever to choke position.
5. Activate the starter switch. Release the key as soon
as the engine starts. Do not crank for more than 10
seconds. Repeat if necessary.
6. Move choke lever to run position after engine starts.
Some choke may be needed until engine is fully
warmed up.
7. Once engine is running and no choke is needed,
slowly let foot clutch pedal up. This will engage the
drive belt and the rotor will turn.
4.2 STARTING (PTO MODEL)
1. Start tractor engine and engage PTO drive clutch (See
tractor owners manual). Increase engine speed to
rated PTO RPM position.
4.3 SHREDDING
1. Place materials to be shredded (grass, leaves, garden
refuse, sticks and branches less the 1-1/2 inches in
diameter and 24 inches long, etc.) into the hopper.
2. If necessary, use a leaf tamper, branch or other
similar object to push material through the inlet
guards.
3. Feed material evenly into the shredder so that the
engine does not lug down or the shredder become
plugged. Attempting to use the clutch to clear a
plugged rotor will cause belt damage. Branches or
items that plug or cause the machine to stall should
be fed in more evenly or put through the chipper
chute.
Check oil level with each use. Some oil usage is normal.
NOTE
Handle fuel (gasoline) with care. It is highly flamable.
Always use an approved container and fill tank
outdoors. Never add fuel to a running or hot engine.
WARNING
If engine kills when engaging foot clutch pedal, either
use more choke or increase engine RPM. When the
clutch is engaged the foot pedal may vibrate or shake
until the engine and rotor have increased to full
operating RPM.
