OIL FILLER CAP
PROCEDURES
1. Position the blower so the engine oil drain plug is
the lowest point on the engine.
2. Place a two quart or larger container under the oil drain plug
for the oil to drain into.
3. Remove the oil drain plug and drain the used oil.
4. Install the oil drain plug and tighten securely.
5. Remove the oil filler cap and refill with the recommended oil
(refer to the Pre-Operation instructions in the Operations
section) and check the oil level.
AIR CLEANER
A dirty air cleaner will restrict airflow to the carburetor. To prevent
carburetor malfunction, service the air cleaner regularly. More
frequent service may be necessary when the blower is operated in
extremely dusty conditions.
CAUTION: DO NOT RUN THE ENGINE WITH THE
AIR CLEANER REMOVED. RAPID ENGINE WEAR WILL
RESULT FROM CONTAMINANTS, SUCH AS DUST AND
DIRT BEING DRAWN THROUGH THE CARBURETOR
AND INTO THE ENGINE.
CLEANING AIR FILTER ELEMENTS
Foam Element:
1. Wash the element in a solution of household detergent and
warm water, then rinse thoroughly. Allow the element to dry
completely.
2. Soak the element in clean engine oil, and squeeze out the
excess oil.
NOTE: the engine will smoke during initial start-up if too
much oil is left in the foam element.
Paper Element:
1. To remove excess dirt, tap the element lightly several times
on a hard surface or blow compressed air through the filter
from the inside out.
2. Do not try to brush the dirt off. Brushing will force dirt into
the filter fibers.
3. Replace the element if it becomes excessively dirty. You can
order/purchase paper elements through Tempest or your
local hardware home improvement store.

COOLING SYSTEM
Frequently remove dirt and debris from the cooling fins, air intake
screen, levers and linkage. This will ensure adequate cooling and
correct engine speed. Refer to the engine manufacturer's owner's
manual for additional cooling system information.
SPARK PLUG
A correctly firing spark plug is essential for the blower to operate
properly. Check the engine spark plug every six (6) months or
every 100 hours by following the listed procedures.
1. Clean the area around the spark plug.
2. Remove and inspect the spark plug.
3. Replace the spark plug if the electrodes are pitted, burned,
or the porcelain is cracked. Check the electrode gap with
a wire feeler gauge and set to the engine manufacturer's
specifications.
4. Make sure the spark plug washer is in good condition, and
start threading the spark plug by hand to prevent cross
threading.
5. After the spark plug is seated, tighten with a spark plug
wrench to compress the washer.
CARBURETOR
All carburetors comply with US federal & state regulations and are
preset by the engine manufacturer. Engine performance may differ
at various altitudes and climates. If you feel that the carburetor on
your blower needs adjusting contact Tempest or your local engine
dealer.
EMISSION CONTROL SYSTEM
US State regulations require that all manufacturers of gas powered
engines furnish written instructions describing the operation and
maintenance of the emission control systems. These instructions
vary depending on engine type. Please refer to your engine
manufacturer owner's manual for specific information and
instructions.
BELT ADJUSTMENT
The blower's drive belt has been adjusted at the factory prior
to delivery. However, the belt should be inspected and checked
after the initial three (3) hours of operation as it may require
retightening due to belt stretch. It should be inspected after every
20 hours of operating time. Operating the blower with a loose
belt will cause excessive wear and reduce performance. Follow the
procedures listed to properly adjust the drive belt.
1. Remove the eight bolts holding the front grille in place and
remove the grille. (Figure 1.1)
2. Remove the blade assemble (detailed instructions on how to
remove the blade assembly are available from Tempest).
3. Loosen the four front engine mount bolts. (Figure 3.1)
4. Use a lever to space or push the engine downward to tighten
the belt. (Figure 3.2) The belt(s) should be snug and have
very little play. DO NOT OVERTIGHTEN THE BELT.
5. Tighten the front engine mount bolts.
6. Reinstall the front grille and test the blower.
BELT REPLACEMENT
The belt on your belt-drive blower should be replaced a minimum
