Full Product Manual

Never use a “pressure washer” to clean your unit.
Water can penetrate tight areas of the machine and
its transmission case and cause damage to spindles,
gears, bearings, or the engine. The use of pressure
washers will result in shortened life and reduce
serviceability.
Do not overfill. Too much grease can create pressure
which could damage seals.
ADJUSTING THE CABLE
To increase belt tension do as follows:
1. Loosen the jam nut A and jam nut B by turning them
with two 12mm wrenches at the same time. (See
Figure 12, Illustration 1)
2. Loosen jam nut A enough so the jam nut B can be
rotated. Then, screw the jam nut B up until desired
cable tightness is reached. (See Figure 12, Illustration 2)
3. Screw the jam nut A down to lock jam nut B. (See Figure
12, Illustration 3)
MAINTENANCE
Maintaining your YARDMAX front tine tiller will ensure long life
to the machine and its components.
PREVENTIVE MAINTENANCE
1. Turn off the engine and disengage all command levers. The
engine must be cool.
2. Keep the engine’s throttle lever in its SLOW position and
remove the spark plug wire from the spark plug and secure.
3. Inspect the general condition of the front tine tiller. Check
for loose screws, misalignment or binding of moving parts,
cracked or broken parts, and any other condition that may
affect its safe operation.
4. Use a soft brush, vacuum or compressed air to remove all
contaminants from the machine. Then use high quality light oil
to lubricate all moving parts.
5. Replace the spark plug wire.

LUBRICATION
Remove the tine assemblies to lubricate the tine shafts at least
once every season. The worm gear housing is pre-lubricated and
sealed at the factory. At the beginning of each season, make sure
enough lubricant inside the worm gear housing. Use portable tool
lithium #0 grease such as Lubricate 6300AA , Lubricate GR-132,
or Multifak, e.g. EP-O.
1. Remove right side tines and place the tiller on level surface.
Allow the transmission to cool before lling with grease.
2. Remove the grease tting screw and air vent screw to ll the
worm gear housing through the lower grease tting hole until
the grease begins to come out from the upper air vent hole.
(See Figure 11)
3. Reinstall the grease tting screw and air vent screw.
