Check Hardware; Tines - Champion 100379 Operator's Manual

100379 - FRONT TINE TILLER
Use clean lubricating oil (#30 weight engine oil is suitable)
and clean general purpose grease (grease containing a metal
lubricant is preferred, if available).
– Remove the wheels, clean the wheel shaft and apply a thin
coating of grease to the wheel shaft.
– Grease the back, front and sides of the depth regulator
lever.
– Remove the tines and clean the tine shaft. Use a file or
sandpaper to gently remove any rust, burrs or rough spots
(especially around holes in shaft). Apply grease to ends of
shaft before installing tines.
– Oil the threads on the handlebar height adjustment screws
and the handlebar attaching screws.
Check for Oil Leaks
Before each use, check the tiller for signs of an oil leak —
usually a dirty, oily accumulation either on the unit or on the
floor.
A little seepage around a cover or an oil seal is usually not
a cause for alarm. However, if the oil drips overnight, then
immediate attention is needed. Ignoring an oil leak can result in
severe transmission damage!
If a cover is leaking, check for loose screws. If the screws are
tight, a new gasket or oil seal may be required.
If the leak is from around a shaft and oil seal, the oil seal
probably needs to be replaced. See your authorized dealer or
contact the factory for service or advice.
IMPORTANT: Never operate the tiller if the transmission is low
on oil. Check the oil level after every 30 hours of operation and
whenever there is any oil leakage.

Check Hardware

Check for loose or missing hardware after every 10 operating
hours and tighten or replace (as needed) before reusing tiller.
Be sure to check the screws underneath the tiller hood that
secure the transmission cover and the Depth Regulator Lever to
the transmission.

Tines

The tines will wear with use and should be inspected at the
beginning of each tilling season and after every 30 operating
hours. The tines can be replaced either individually or as a
complete set. Refer to the parts list for tine identification and
part numbers.
A. Tine Inspection:
With use, the tines will become shorter, narrower and pointed.
Badly worn tines will result in a loss of tilling depth, and
reduced effectiveness when chopping up and turning under
organic matter.
B. Removing/Installing a Single Tine:
1. With the engine shut off and the spark plug wire
disconnected, remove the M10×25 bolt, lock washer, flat
washer and M10 nut that attach a single tine to a tine
holder. If needed, use penetrating oil on the nuts.
2. When installing a single tine, be sure to position it so that
its cutting edge (sharp) will enter the soil first as the tiller
moves forward. Hand tighten completely.
C. Removing/Installing a Tine Assembly:
1. A tine assembly consists of eight tines mounted on a tine
holder.
2. If removing both tine assemblies, mark them "left" and
"right" before removal. Remove (2) pins and (2) cotter
pins that secure the tine assembly to the tine shaft. If
necessary, use a rubber mallet to tap the tine assembly
outward off the shaft.
3. Before reinstalling the tine assembly, inspect the tine
shaft for rust, rough spots or burrs. Lightly file or sand, as
needed. Apply a thin coat of grease to the shaft.
4. Install each tine assembly so that the cutting (sharp) edge
of the tines will enter the soil first when the tiller moves
forward.
5. Bend cotter pins once inserted to prevent the pins from
coming out.
