Bolens 12228 - Manual (Page 12)

12 Section 5: Maintenance
Before inspecting, cleaning or servicing the machine, shut off engine, wait for moving parts to stop, dis-
connect spark plug wire and move wire away from spark plug.
Failure to follow these instructions can result in serious personal injury or property damage.
WARNING
Replacing Worn Tine Sections
The tines are excessively worn if tilling
takes much longer than before and the soil
is not being mixed thoroughly enough.
1. Prop the machine forward so it rests on
the front of the tubular carrying handle.
The work surface should be flat and firm.
2. Remove the ring lock pin (A, Figure 12)
from both sides of the unit. Remove the
old tine sections and replace them with
new tine sections. Refer to Figure 12 and
the tine position shown in the Parts List
for tine positioning details. Insert the ring
lock pins through the rounded side of the
tine shafts and snap the ring over the shaft
(see DETAIL - Ring Lock Pin, Figure 10, in
Section 4).
STORAGE
IMPORTANT: It is important to prevent
gum deposits from forming in essential
fuel system parts such as carburetor, fuel
filter, fuel hose, or tank during storage.
Also, experience indicates that alcohol-
blended fuels (called gasohol or using
ethanol or methanol) can attract moisture
which leads to separation and formation of
acids during storage. Acidic gas can
damage the fuel system of an engine while
in storage.
Off-Season Storage
• Protect the engine and perform recom-
mended engine maintenance by fol-
lowing the engine storage instructions
found in the separate Engine Owner’s
Manual.
NOTE: Be sure to protect the fuel lines,
carburetor and fuel tank from gum
deposits by removing the fuel or by
treating the fuel with a stabilizer. See
Engine Owner’s Manual for more infor-
mation.
• Remove tines. Clean all soil and debris
from dust covers and tine shaft. Lubri-
cate tine shaft with light oil. Replace
tines.
• Cover engine and store equipment in a
dry, sheltered location.
• Never store the unit when there is fuel
in the fuel tank.
• Never place the unit near any source of
sparks or open flame (such as from a
hot water heater, a space heater or
clothes dryer).
Failure to comply can result in serious
personal injury or property damage.
