Troy-Bilt 12157 - Manual (Page 16)

Remounting the tine gangs takes just a couple
of minutes. The Figures to the right show the
normal tine pattern where there is a narrow gap
between the center (inner) tines, and the special
stony soil tine pattern where the inner tine gangs
have been swapped in position. The stony pat­
terns creates a wider gap between the inner tine
gangs — rocks are much less likely to become
lodged between them and the tine hood.
IMPORTANT: Remember that when you
remount the tines on the tine shaft, they must be
turned in the direction that allows the curved por­
tions of the blades to enter the soil first! Don’t
turn the tines so they face backwards or tilling
will be very difficult. Figure 11D: Normal tine gang pattern.

Maintenance
ENGINE LUBRICATION
The engine on your tiller is a two-cycle (“two-
stroke”) engine. Engine lubrication is provided
by mixing the proper type and amount of two-
cycle oil with the gasoline. Refer to “The
Gasoline/Two-Cycle Engine Oil Mixture” for cor­
rect proportions and mixing instructions.
TRANSMISSION LUBRICATION
The transmission was factory-lubricated with
high-quality grease and should not require any
additional regular lubrication.
However, you should check for sufficient lubri­
cant after the initial five hours of operation, and
every twenty-five operating hours afterward.
If needed, use grease that is a high quality, au­
tomotive petroleum-base grease usually avail­
able at most hardware or auto parts stores.
To check the transmission:
1. Lay the machine on the left side so the tine
shaft is vertical.
2. Remove both right-side tines (see “Tine
Removal” this Section).
3. Clean any dirt or debris away from the trans­
mission so none will enter the housing.
4. Remove all three threaded plugs from the right
side of the transmission. See Figure 12 for their lo­
cations. Lubricant should be visible in the top two
holes. If so, replace the three plugs securely. If lu­
bricant is needed, see the following steps.
To lubricate the transmission:
5. Place the nozzle of a grease gun on the rim of
the middle hole. Push the nozzle firmly up
against the opening.
