SECTION 6:   MAINTAINING YOUR TILLER
WARNING: 
Disconnect the spark plug
wire and ground it against the engine
before performing any repairs or
maintenance.
Engine
Refer to the separate engine manual for engine 
maintenance instructions.
Maintain 
engine oil
 as instructed in the separate 
engine manual packed with your unit. Read and follow 
instructions carefully.
Service 
air cleaner
 every ten hours under normal 
conditions. Clean every hour under extremely dusty 
conditions. Poor engine performance and flooding 
usually indicates that the air cleaner should be 
serviced. To service the air cleaner, refer to the 
separate engine manual packed with your unit.
IMPORTANT:
 Never run your engine without air cleaner 
completely assembled.
The 
spark plug
 should be cleaned and the gap reset 
every 25 hours of engine operation. Spark plug 
replacement is recommended at the start of each tiller 
season; check engine manual for correct plug type and 
gap specification.
Clean the engine
 regularly with a cloth or brush. Keep 
the cooling system (blower housing area) clean to 
permit proper air circulation which is essential to engine 
performance and life. Be certain to remove all dirt and 
combustible debris from muffler area.
Lubrication
Transmission
The transmission is pre-lubricated and sealed at the 
factory. It requires no checking. See an authorized 
service dealer for any service issues. 
Clutch Handle
Lubricate the pivot point on the clutch handle and the 
cable at least once a season with light oil. The control 
must operate freely in both directions.
Pivot Points
Lubricate all pivot points and linkages at least once a 
season with light oil.
Tine Shafts
Remove tine assemblies and lubricate the tine shafts at 
least once a season.
Wheel Shafts
Remove wheel assemblies and lubricate the axle shafts 
at least once a season.
Cleaning Tine Area
Clean the underside of the tine shield after each use. 
The dirt washes off the tines easier if rinsed off 
immediately instead of after it dries. Always towel dry 
the tiller afterwards and apply a light coat of oil or 
silicone to prevent rusting or water damage.
IMPORTANT:
 Never use a "pressure washer” to clean 
your tiller. Water can penetrate tight areas of the tiller 
and its chain case and cause serious damage to the 
unit.
Belt Replacement
Your tiller has been engineered with a belt made of 
special material (Kevlar Tensile) for longer life and 
better performance. It should not be replaced with an 
off-the-shelf belt. Order all belts through your 
authorized service dealer. 
Disconnect and ground spark plug wire against the 
engine.
Remove the two hex washer screws from the front 
of the belt cover and remove the lock nut and flat 
washer from the side of the belt cover.
Remove the belt cover. See Figure 11.
Figure 11
Remove the hex screw and idler pulley from the 
idler bracket assembly. See Figure 12.
Reassemble the new belt and reattach idler pulley 
to secure in place. 
Replace belt cover assembly and secure with the 
hardware removed earlier.
