Never leave the chipper run ning unattended.
Do not attempt alterations, r epairs, or adjustments while the ch ipper head is
turning. Always disconnect the PTO and stop the motor.
ALWAYS make sure the fee d roll drive-shaft and pivots are pro perly lubricated.
ALWAYS make sure the fee d roll clutch is properly lubricate d and the clutch
releases when the handle i s pushed toward the chute.
ALWAYS make sure the PT O shaft does not come apart or bo ttom out during
the normal lifting range.
Check the chip pile to see if the blades need to be serviced. L ong slivers in the
chip pile are a good indica tion that the blades are dull and need sharpening.
CAUTION: Turn the chipper head ov er by hand be fore applying power to
make sur e that the hea d is clear, all the bolts are clear and the knives clear the
case and cutter bar.
DRIVE-LINE SAFETY CHECKLIST

DRIVE-LINE SPECIFICATIONS The first step toward a safe application is

to specify and test the drive-line to make sure it operates properly

under expected field conditions.

Specify and test the proper siz e joints and telescoping members b ased upon the
power required by the impl ement, speed of rotation, joint angles, shock loads, and
expected life. More informa tion may be found in all drive-line man ufacturers’ catalogs.
Design and test the hitch angl e to prevent the drive-line from:
Extending beyond the recommended maximum length.
Bottoming out.
Reaching a position that allows joints to lock.
Exceeding the maxim um allowable angle for constant vel ocity (CV) joints.
Specify and test telescoping m embers to allow the lowest possibl e thrust loads,
considering the expected wo rking conditions.
Specify and test torque limiters t o control excessive shock loads. Where necessary,
specify and test overrunning c lutches to prevent inertial loads f rom overpowering the
tractor.
Specify and test torque limiters t o control excessive shock loads.
Where necessary, specify and t est overrunning clutches to prevent i nertial loads from
overpowering the tractor.

HAZARD REDUCTION The second step in specifying a safe drive-line

application is to eliminate as many hazards as possible.
