PRIMARY MAINTENANCE
On 4-cycle engines with an oil
level plug, don’t be fooled onto
thinking the engine has
sufficient lubricating oil if you
can see “some” oil in the
opening – the level should
always be brought up to the
point of overflowing at the
top of the fill hole.
On 2-cycle engines, lubrication must be
provided by an exact mixture of gasoline
and 2-cycle air-cooled engine oil. A 2-cycle
engine that is mistakenly run on straight
gasoline will be ruined in less than 5
minutes! If you keep straight gasoline in
addition to pre-mixed 2-cycle engine fuel,
be sure the containers are clearly marked
to avoid mix-up.
Snapper 2-cycle engines require a 32 to 1
mixture of gasoline and BIA certified TC-W
oil such as Snapper’s 2-cycle engine oil.
Many of the 2-cycle engine oils on the
market today make fantastic claims, but for
the best performance and long engine life,
always use Snapper 2-cycle oil. Pre-mix the
fuel and always shake the container before
filling the tank.
Change oil at regular intervals using a high
quality oil such as Snapper’s small engine
formulated 4-cycle engine oil. Refer to the
engine owner’s manual for oil details.

Keep in mind that dirt is your engine’s
enemy #1 both internally and externally!
Internally, dirt will quickly ruin an engine
and externally it will cause overheating and
resulting internal damages. Damage caused
by improper lubrication, poor air cleaner
service or overheating due to dirt cannot be
covered under warranty.
It only takes a few moments to service the engine
(and equipment) on a routine basis but the rewards
will be a quick starting, responsive engine that will
provide long satisfactory service with minimum
maintenance cost. The pre-start checklist in the next
column and instructions in your Snapper Operator’s
Manual are designated to help you keep your Snapper
in top operating condition with minimum effort!
