Maintenance - EarthWise TC70016 Manual Del Operador

WARNING: Before carrying out maintenance operations, disconnect power supply.
Before each use check the extension cord for
signs of damage or ageing. Replace the cable if
it is cracked, split or otherwise damaged. Check the
condition of the tines and ensure that all threaded
connections are securely tightened. If the tines
become dull or blunt, sharpen or replace them. Call
our customer service help line at 1-800-313-5111
for assistance.
Once per season lubricate the tines and shaft. At
the end of the season, check the tiller/cultivator for
damage prior to storing. Repair or replace damaged
or broken parts.
CAUTION: Always clean the tiller/cultivator after
each use. Failure to carry out proper cleaning can
result in damage to the tiller/cultivator or result in
poor performance.
Clean the underside of the motor support plate and
housing around the tines with a scrub brush, and a
soft cloth dampened with a mild soap and water
mixture. Never use a water hose to clean the
tiller! To remove soil and debris from the transmis-
sion and tines, use a stiff brush or a dampened
cloth. Clean the vents on the motor housing and
remove any remaining grass or dirt. Once cleaned,
wipe the tines and shaft dry and apply a light coat
of oil to prevent rust.
Tines maintenance: Worn tines invite poor
performance and overload of the motor. Check tines
before each use. Sharpen or replace the tine
assemblies with new ones when necessary. Call
1-800-313-5111 for assistance.
WARNING: Injury can occur while working on the
tines. Wear protective gloves.

MAINTENANCE

Replace worn or damaged parts with original replace-
ment parts only. Parts from another tiller/cultivator may
not fit properly causing an unsafe situation.
Make sure all protective devices are secure and in
good condition. Repair or replace if necessary.
Lubrication (Fig. 11): The tines drive transmission
case has grease installed at the factory. It is not
required that the grease level be checked nor
recommended that grease be added during the first 2
years of use. After the second season of use, follow
the directions as described below:

Drain screw plugs are located on the right side of
transmission housing. Lay the tiller/cultivator on its left
side and clean the transmission of dirt and debris prior
to removing the drain screw plugs. If necessary,
remove tine assemblies to have better access to the
drain screw plug. Use a 5mm hex key to unscrew the
plugs.
Using a squeeze bottle or tube, add approximately 2.4
oz. (70ml) of auto gear lube. Do not overfill. When
completed, reinstall both drain screw plugs into the
transmission.
