If consistent plugging occurs, it can be caused by one of several reasons:
1. The bale handlers do not feed the bales at a consistent rate and/or do not guide the bales properly
onto the power feed mechanism after they remove the strings or wires, leaving gaps in the stream of
bales or the bats lay flat on the tray.
2. The power band is out of adjustment, causing it to slip.
3. The clutch is out of adjustment and is slipping.
4. Check that the necessary beater chains are installed.
5. Operator is feeding the mulch material too fast and overloading the shredder housing. The blower
will only suck separated mulch fibers into the blower housing; this separation process takes longer
with wet and hard material than with dry mulch material.
HYDRAULIC SYSTEM:
The hydraulic system on your Finn Straw Blower consists of a pump, reservoir with suction strainer, oil
filter, and power feed hydraulic motor with flow control valve set to operate at 2000 psi (13790 kPa). The
most important maintenance areas are the hydraulic oil and filtration. The reservoir holds 8 gallons of ISO
Grade 46 Hydraulic Oil. Hydraulic oil should be replaced per the lubrication schedule or if the oil becomes
milky or gives off a burnt odor. Hydraulic oil filter must be replaced with a 25 Micron absolute filter – Finn
part # 021618. The following checks will keep your Finn Straw Blower in proper operating condition:
1. Check oil level once a week. Add additional oil when level goes down below 1-1/2" (3.8 cm).
2. Change oil filter on oil tank every 500 hours of operation.
3. Check and clean suction strainer once a year or whenever the oil is changed.
4. Change hydraulic oil whenever the color turns to milky white, (change is caused by water getting
into hydraulic system) or if oil gives off a burnt odor.
5. Keep all fittings and hoses tight and leak free.
6. Keep system clean at all times.
CAUTION: Do not start or run the engine without hydraulic oil in the res-
ervoir or with a closed reservoir ball valve as permanent dam-
age to the hydraulic pump will occur.
