in the engine.

2. Slowly pour oil into the oil fill tube until the oil

Do not overfill. (Max. fill: 20 oz., type: SAE 30

Install the Recycle Plug or
Grass Bag
No Parts Required
Procedure
You must correctly install the recycle plug (for recycling
or side-discharging) or grass bag (for bagging) or the
engine will not start.
The mower has a safety switch, located at the bottom
of a channel on the top, right rear of the mower, that
prevents the mower from operating without a recycle
plug or grass bag. This prevents the mower from
throwing debris at the operator through the rear chute.
For the switch to detect the presence of the recycle plug,
the top of the recycle plug lever must lie fully in the
bottom of the channel (Figure 7).
1. Top of recycle plug lever in switch channel
1. Insert the recycle plug into the mower, if it isn't
already installed (Figure 8).
