ENGINE
Major repairs should NOT be attempted without a
thorough knowledge of all components of the
engine. Therefore, we strongly recommend having
service or repairs performed by an authorized
engine dealer.
General maintenance, filter changes, oil changes,
etc., should be performed as recommended by the
Briggs & Stratton Engine Operation and
Maintenance Manual (#67-945308). Use the engine
manual as a detailed guide for all matters
concerning the engine. The following is a
condensed version of maintenance procedures:
1. Check the engine oil level daily, when in use.
Make certain that proper oil level is maintained.
NEVER overfill. Use high quality detergent oil of
at least API (American Petroleum Institute)
service class SJ or SH. Select the viscosity
based on the air temperature at the time of
operation as shown in the following table.
NOTE: Using less than service class SF or SG
oil or extending oil change intervals longer than
recommended can cause engine damage.
