lUbricaTion
After every 10 operating hours, oil or grease the lubrication points. Use
clean lubricating oil (#30 weight motor oil is suitable) and clean general
purpose grease (grease containing a metal lubricant is preferred, if
available).
• Remove the tines and clean the tine shaft. Use a file or sandpa-
per to gently remove any rust, burrs or rough spots (especially
around the holes in the shaft). Apply grease to the ends of the
shaft before installing the tines.
• Remove the belt cover and lubricate all the pivot points and
linkages with a light coat of oil. Keep the belts free of lubrication.
• The chain case is pre-lubricated and sealed at the factory and
requires no maintenance.
harDWare
Check for loose or missing hardware after every 10 operating hours
and tighten or replace — as needed — before reusing the tiller. Be
sure to check the screws underneath the tiller hood that secure the
transmission cover and the Depth Regulator Lever to the transmission.
Warning
Before performing any type of maintenance on the machine, wait for
all parts to stop moving and disconnect the spark plug wire. Failure
to follow this instruction could result in personal injury or property
damage.
belT rePlaceMenT
If the drive belt needs to be replaced, make sure you use only a
factory authorized belt listed in the Parts pages of this operator's
manual, as an "over- the-counter" belt may not perform satisfactorily.
The procedure requires average mechanical ability and commonly
available tools.
To replace the Drive belt, follow these steps:
1. Remove the belt cover from the left side of the tiller by removing
the two self tapping screws and hex stop nut and washer. See
Figure 27.
2. Remove the idler pulley bolt and move the belt from under the
idler pulley keeper. See Figure 28.
3. Remove the belt keeper assembly located behind the engine
pulley by removing the two hex bolts and lock washers. See
Figure 28.
4. Remove the old belt from around the transmission pulley and
install the new belt. See Figure 28.
5. Follow the instructions in reverse order to re-install the belt keeper
and idler pulley.
NOTE: Upon reassembly, make certain that the idler pulley keeper
is as shown in Figure 28. Take note of the notch on the bottom of the
keeper and the alignment when reassembling with the replacement
belt.
