TILLER LUBRICATION
After every 10 operating hours, oil or
grease the lubrication points shown in
Figure 5-1 and described below. :
Use clean lubricating oil (#30 weight motor
oil is suitable) and clean general purpose
grease (grease containing a metal lubricant
is preferred, If available). y ::
• Remove the wheels, clean the wheel shaft
(A, Fig. 5-1) and apply a thin coating of :
grease to the wheel shaft : : : : : :
• Grease the back, front and sides of the
depth regulaior lever (B, Fig. 5-1).

• Remove the tines and clean the tine shaft
(C, Fig. 5-1). 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 install­
ing tines.
• Oi! the threads on the handlebar height
adjustment screws and the handlebar
attaching screws (D, Fig. 5-1). : : : : : : : : : : : : : :

CHECK FOR OIL LEAKS
Before each use, check the tiller for signs of
an oil leak — usually a dirty, oily accumu­
lation 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. How­
ever, if the oil drips overnight, then immO'
díate attention is needed. Ignoring an oil
leak can result in severe transmission
damafife/ ■ ■ ■ ■-

If a cover is leaking, check for loose :
screws. If the screws are tight, a new
gasket or oil sea! 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 fpr 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 af­
ter every 10 operating hours and tighten
or replace (as needed) before reusing
tiller/:: 7 :7 :'VV:/
Be sure to check the screws underneath
the tiller hood that secure the transmis­
Sion cover and the Depth Regulator Lever
to the transmission. -:
CHECK TIRE PRESSURE
(Models with pneumatic tires)
Check the air pressure In both tires. The
air pressure should be between 15 PSI
and 20 PSI (pounds per square i
Keep both tires equally inflated to help
prevent machine from pulling to one
side. ..... .. ■ .
TRANSMISSION
GEAR OIL SERVICE
Check the transmission gear oil level
after every 30 hours of operation or :
whenever you notice any oil leak. Oper­
ating the tiller when the transmission is
low on oil can result in severe damage.
A. To Check the Transtnission
Gear Oil Level:
1. Check the gear oi! level when the
transmission is cool. Gear oil will
expand in warm operating temperatures
and this expansion will provide an incor­
rect oi! level reading. : : : : : : : /
2. With the tiller on level ground, pull the
Depth Regulator Lever all the way up.
3. Remove the oil fill plug (A, Fig. 5-2)
from the transmission housing and look
inside the oil fill hole to locate the main
drive shaft situated below the hole.
