Operating Precautions
■This Shindaiwa tiller/cultivator
attachment is specifically
designed for use on Shindaiwa
PowerBroom and Trimmers.
Installation and/or use on any
other model, brand or type of
power tool is not approved by
Shindaiwa. Attempts to use on
non-approved models can
damage the equipment and
cause accidents, serious injury
or death.
■Always make sure the Tiller/
Cultivator attachment is
properly installed and firmly
tightened before operation.
■Never use a cracked or warped
tine: replace it with a service-
able one and make sure it fits
properly.
■Never smoke or light fires near
the engine. Fuel is very flam-
mable and fire could lead to
serious personal injury or
property damage.
■Make sure there are no missing
or loose fasteners, and that the
stop switch and throttle controls
are working properly.
WARNING!
■Make sure there is always
good ventilation when operat-
ing this unit. Fumes from
engine exhaust can cause
serious injury or death. Never
run the engine indoors!
■Before starting the engine,
make sure the tines are not
contacting anything.
■Always stop the engine
immediately and check for
damage if you strike a foreign
object or if the unit becomes
tangled. Do not operate with
broken or damaged equip-
ment.
■Stop the engine immediately if
the unit suddenly begins to
vibrate or shake. Inspect for
broken, missing or improperly
installed parts or attachments.
■Never transport the unit or set
it down with the engine
running. An engine that’s
running could be accidentally
accelerated causing the tines
to rotate.
Always keep the unit as clean as
practical. Keep it free of loose
vegetation, mud, etc.
CAUTION!

Starting and Fueling
For detailed instructions on general
safety procedures, fueling, starting,
and stopping the Shindaiwa
PowerBroom or Trimmer, refer to the
appropriate Owner’s Manual for your
model.
WARNING!
KEEP CLEAR of tines during
starting operations! The tines may
rotate during startup.
General Operation
Your Shindaiwa Tiller/Cultivator's
reversible tines allow you to quickly
change from operation as a cultivator-
weeder to an aggressive tiller for
quickly digging a new garden or
landscaping plot. For best operation in
either mode:
WATER the area to be tilled at least
24 hours before your planned tilling
operation; then water again about 3
hours before the actual tilling.
PULL the tiller slowly toward you
when tilling or cultivating.
FOR DEEP TILLING (up to 10"
depth) use full throttle while slowly
rocking the tiller back and forth
over the work area.
SHALLOW WEEDING in soft soils
is easiest when the tines are
installed in the cultivating configu-
ration, with additional depth
available by using a gentle rocking
motion as described above.
HEAVY WEEDS or weeding in
harder soils may require reversing
the tines to the more aggressive
tiller configuration.
WARNING!
BURN DANGER! The gearcase
will become very hot during
normal operation.

the seal and lift the plate from the
gearcase. See Figure 17.
NOTE:
It may be necessary to use a heat gun
to soften the sealer material.
300-hour Maintenance
Gearcase Lubrication
The gearcase should be filled with 60
cc (2.0 fl.oz.) of Mobil SHC634
Synthetic Gear Oil. A maximum of 75-
80 cc can be used; but never to exceed
80 cc. Operation with excessive oil
level will result in high operating
temperatures. Do not overfill!
Figure 17
Fill to
this level
4. Turn the gearcase to the RH side
and and allow all used gearcase oil
to drain into a small container.
5. Place the gearcase on the LH side
and supported so the outer tube is
parallel to the ground. Refill the
gearcase with 60 cc (2.0 fl.oz) of
Mobil SHC634 Synthetic Gear Oil
to the bottom of the chamfer on the
output gear. The correct oil depth
is 0.60" (15.5 mm). See Figure 18.
DO NOT OVERFILL!
6. Inspect the sideplate for damage
and clean off all remaining liquid
gasket material with brake cleaner
or acetone. Coat the outer sealing
flange of the sideplate with Loctite
Ultragrey Silicon Sealant or
Threebond No. 1104 Liquid
Gasket.
7. Replace the cover and install the
four sideplate screws. Tighten
securely.
