D. Cleaning/Replacing Air Cleaner
Your engine has an air cleaner which helps prevent
premature engine wear and failure. NEVER run engine
without complete air cleaner installed on engine. Your air
cleaner periodically needs to be cleaned or replaced.
NOTE
Contact your Authorized Tecumseh Servicing Dealer for a
Tecumseh Air Cleaner.
I. Servicing Foam Pre-Filter
Clean foam pre-filter every 3 months or every 25 operating
hours. Clean daily if used in extremely dusty conditions.
After removing the pre-filter, follow these cleaning
instructions below:
1. Wash in warm water and detergent solution then press
(DO NOT twist) until all dirt is removed.
2. Rinse thoroughly until water is clear.
3. Wrap in a clean cloth and press (DO NOT twist) until
completely dry.
NOTE
DO NOT oil foam pre-filter.
4. Replace foam pre-filter onto paper filter.
II. Servicing Paper Filters
Paper filters cannot be cleaned and must be replaced once
a year or every 100 operating hours; more often if used in
extremely dusty conditions. Replacement filters are
available at an Authorized Tecumseh Servicing Dealer.
NOTE
DO NOT put oil on or clean a paper filter.
III. Filter Removal/Installation
1. Remove wing nuts from air cleaner cover. See Figure 18.
2. Remove air cleaner cover while lifting upward then
outward.
3. Remove fasteners.
4. Remove and inspect filter(s) for discoloration or dirt
accumulation. If either is present, see "I. Servicing
Foam Pre-Filter" instructions on page 11. or see
"II. Servicing Paper Filters" instructions on page 11.
5. Clean inside of cover and body thoroughly.
6. Install paper filter (see equipment manufacturer’s
instructions).
7. Install fasteners.
8. Install foam pre-filter (see equipment manufacturer’s
instructions).
9. Install cover by pushing down onto body securely.
10. Install wings nuts and tighten securely.
E. Carburetor
If you think your carburetor needs adjusting, see your
nearest Authorized Tecumseh Servicing Dealer. Engine
performance should not be affected at altitudes up to 7,000
feet
(2,134 meters)
. For operation at higher elevations,
contact your Authorized Tecumseh Servicing Dealer.
F. Engine Speed
To avoid serious injury or death, DO
NOT modify engine in any way.
Tampering with the governor setting can lead to a runaway
engine and cause it to operate at unsafe speeds. NEVER
tamper with factory setting of engine governor.
Running the engine faster than the speed set at the factory
can be dangerous and will VOID THE ENGINE
WARRANTY.
G. Adjustments
DO NOT make any engine adjustments. Factory settings
are satisfactory for most conditions. If adjustments are
needed, contact your Authorized Tecumseh Servicing
Dealer.
