Servicing The Engine Oil - Toro Z149 Z Master 74411 Operator's Manual

Installing the Filters
Important: To prevent engine damage,
always operate the engine with both air filters
and cover installed.
1. If installing new filters, check each filter for
shipping damage. Do not use a damaged filter.
2. If the safety filter is being replaced, carefully
slide it into the filter body (Figure 28).
3. Carefully slide the primary filter over the safety
filter (Figure 28).
Note: Ensure that it is fully seated by pushing
on the outer rim of the filter while installing it.
Important: Do not press on the soft
inside area of the filter.
4. Install the air cleaner cover with the side
indicated as UP facing up and secure the
latches (Figure 28).

off, and remove the key.
