MAINTENANCE

WARNING:

When servicing, use only identical replacement parts.

Use of any other parts may create a hazard or cause

product damage.

WARNING:

Always wear eye protection with side shields marked to

comply with ANSI Z87.1, along with hearing protection.

Failure to do so could result in objects being thrown into

your eyes and other possible serious injuries.

WARNING:

Before inspecting, cleaning, or servicing the machine,

shut off engine or motor, wait for all moving parts to stop,

and disconnect spark plug wire and move it away from

spark plug or disconnect from power supply. Failure to

follow these instructions can result in serious personal

injury or property damage.

GENERAL MAINTENANCE

Avoid using solvents when cleaning plastic parts. Most

plastics are susceptible to damage from various types of

commercial solvents and may be damaged by their use. Use

clean cloths to remove dirt, dust, oil, grease, etc.

WARNING:

Do not at any time let brake fluids, gasoline, petroleum-

based products, penetrating oils, etc., come in contact

with plastic parts. Chemicals can damage, weaken or

destroy plastic which may result in serious personal injury.

You can often make adjustments and repairs described here.

For other repairs, have the product serviced by an authorized

service dealer.

TINE MAINTENANCE

 Occasionally apply a few drops of oil to the shaft to keep

the tines free on the shaft.

 If tines are being replaced due to wear, all four tines

should be replaced as a set.

REGULAR TINE PATTERN

See Figure 6.

For most applications, the regular tine pattern will work best.

This is the pattern set by the factory.

NOTE: Pay attention to the hub position in relationship to

the tines.

NARROW TINE PATTERN

See Figure 7.

When tilling in confined areas or rows, a narrow tine pattern

may be required. For a narrow tine pattern:

 Remove hitch pin from each side of the tiller.

 Remove the left and right outer tines (A and D).

 Remove felt washers.

 Replace hitch pin in alternate holes on each side of shaft.

NOTE: Do not force the tines on or off the shaft. If you

experience difficulties when removing the tines, apply some

penetrating oil on the shaft. When reinstalling the tines, make

sure to clean and oil the shaft and the tine hubs.

STONY OR ROCKY SOIL TINE PATTERN

See Figure 8.

If you are tilling in stony or rocky soil and experience con-

tinual rock jams, there is an additional tine pattern that will

help correct the problem. In the stony soil tine pattern, the

center gap is wider than in the regular tine pattern. This will

require additional passes to till the area. For a stony soil

tine pattern:

 Remove hitch pin from each side of the tiller.

 Remove tines and felt washers from the shaft.

 Reinstall tines B and C on opposite sides of the shaft.

When facing the tiller attachment, tine B will now be on

the left and tine C will be on the right.

 Reinstall felt washers.

 Reinstall tines A and D. Tines D and B will now be on one

side, with tines A and C on the other.

 Replace hitch pins.

ATTACHING THE STORAGE HANGER

See Figure 9.

There are two ways to hang the attachment for storage.

 To use the hanger cap, push in the button and place the

hanger cap over the end of the attachment shaft. Slightly

rotate the cap from side to side until the button locks into

place.

 The secondary hole in the attachment shaft can be used

for hanging purposes as well.

STORING THE ATTACHMENT

 Store the attachment indoors in a well-ventilated place

that is inaccessible to children.

 Keep away from corrosive agents such as garden chemi-

cals and de-icing salts.
