MAINTENANCE
AIR FILTER
Contaminated air filters cause a reduction in engine
performance and increase fuel consumption with more
pollutants in the exhaust gas. Engines are less likely to
start readily with a contaminated air filter.
As a basic principle therefore, the air filter should be
cleaned as follows before starting work, and
intermittently in very dusty conditions:
Before opening the air filter, close the choke to prevent
dirt entering the carburetor.
• Push tab (a) in, only slightly open air filter lid (11) and
remove by rotating gently back and forth.
• Remove foam filter (c) from the lid and clean the area
around the filter.
• Thoroughly clean air filter casing (d) and air filter
cover (11) on the inside, using a paintbrush or by
carefully blowing on them.
• Clean filter insert (c) by shaking it out or carefully
blowing on it.
If the filter insert is damaged or so contaminated that it
is impossible to clean, replace it with the original spare
part (part no. 20 48 406).
• Insert the new or cleaned foam filter into the
air filter lid.
• Position the air filter cover with both tabs (b) [inside,
opposite tab (a)] in the corresponding two pockets
(b') of the filter casing.
• Press air filter cover against the filter casing until tab
(a) clicks audibly into place.
SPARK PLUG
Check the spark plug annually.
• Engine must be cool.
• Press the top tab of the spark
plug cover (16) down (a),
push back (b) and remove.
• Disconnect the
spark plug cap.
• Unscrew the spark plug
and dry electrodes.
The spark plug should be replaced after 50 hours of
operation or if the electrodes are badly worn.
Do not turn the engine over while the spark plug has
been removed or the spark plug cap has been
disconnected from the ignition cable.
Use spark plugs with the following description:
BOSCH: Super R10 USR4AC (Original plug included,
gap .020 inch)
NGK: CMR6H or comparable (Replacement/
Service plug .025 inch.)
Only use spark plugs where the contact nut has been
firmly fitted. Loose connections may produce sparks,
which can cause fire. Before restarting the engine,
check the high-tension ignition cable for any damage to
it's insulation and ensure the cable is connected
securely to the spark plug cap.
• Insert the spark plug into the cylinder head and
tighten it.
• Push the spark plug cap firmly over the spark plug.
• Position the spark plug cover onto the housing by
aligning it with the guiding pins, push down and click
into place.
TRANSMISSION
Transmissions are maintenance free, they require no
adding of grease or checking.
SECURING YOUR AUGER DURING TRANSPORT
With your purchase of a StrikeMaster power auger, you
have acquired one of the world's best precision cutting
machines. A little prevention goes a long way. Whether
you transport this machine in a truck, snowmobile, ATV
or sled be sure to secure it down to prevent damage.
Because of today's fuels STRIKEMASTER cannot
guarantee results. For summer storage or any period of
time exceeding four weeks, the following steps should
be carried out:
WET/NORMAL STORAGE : (recommended)
• Empty fuel tank contents and dispose of properly
• Fill fuel tank to 1/4 capacity with fresh fuel,
oil and stabilizer
• Start and run engine for 2-3 minutes, varying throttle
input, then turn switch to the OFF positron
• If possible, run engine every 30 days for 2-3 minutes.
DRY STORAGE:
• Empty fuel tank contents and dispose of properly
• Fill fuel tank to 1/4 capacity with fresh fuel,
oil and stabilizer
• Start and run engine for 2-3 minutes, varying throttle
input, then turn switch to the OFF position
• Empty fuel tank contents
• Restart engine and allow engine to idle until engine
stalls (due to lack of fuel)
Suggested steps for general cleaning and storage:
.025 inch
• Spray WD-40 or apply oil onto the blades and blade
screws to reduce rust and corrosion
• Clean the engine thoroughly with a clean cloth
• Place a cover over engine assembly
• Store indoors in a well-ventilated low humidity area
• Store auger with blade guard attached
